About Hume AI

Hume AI on the GrabOn India coupon page covers the US-origin empathic voice AI and expression-measurement and text-to-speech SaaS platform operating under Hume AI Inc and headquartered in New York City. The company was founded in 2021 by Dr Alan Cowen, the Founder and CEO who came from a Google research background pioneering semantic space theory, a computational approach to understanding emotional experience and expression. Hume AI raised a USD 50 million Series B funding round in March 2024 led by EQT Ventures with participation from Union Square Ventures, Nat Friedman and Daniel Gross, Metaplanet, Northwell Holdings, Comcast Ventures, and LG Technology Ventures. The mission of the company is to build AI optimised for human well-being by aligning artificial intelligence with the proxies of human happiness.

Hume AI sits at the intersection of three product families. The Empathic Voice Interface (EVI) is the conversational voice-to-voice AI system powered by an empathic large language model (eLLM) that knows when the user is finished speaking and learns to generate vocal responses optimised for user satisfaction. EVI 3 is the latest version and the first speech-language model that can speak expressively with any voice (real or designed) without fine-tuning, available through the Hume API. The Octave Text-to-Speech (Octave TTS) is the first text-to-speech system that understands what it is saying with the ability to generate custom AI voices with adjustable emotions, ranging from a free 10,000 characters per month up to enterprise volumes. The Expression Measurement API provides APIs to measure hundreds of dimensions of human expression across audio, video, and text which distinguishes Hume from the competitor stack focused primarily on TTS generation.

The Hume AI pricing structure splits into seven primary plans. The Free plan covers the basic-evaluation workflow with limited monthly minutes. The Starter plan at USD 3 per month adds incremental usage and basic feature access. The Creator plan at USD 14 per month covers the indie-developer-and-creator workflow with the commercial-licence path. The Pro plan at USD 70 per month covers the higher-usage developer and team workflow. The Scale plan at USD 200 per month covers the production-deployment workflow with team-seat allocation. The Business plan at USD 500 per month covers the enterprise-evaluation-and-mid-market deployment workflow. The Enterprise plan carries custom pricing with the volume-tier rate on the EVI API as low as USD 0.02 per minute on the highest-volume application. The EVI 2 API is priced at USD 0.072 per minute (30 percent lower than EVI 1 at USD 0.102 per minute) with EVI 3 pricing TBA following the same usage-based-with-enterprise-discounts pattern.

Indian buyer profiles at Hume AI split into five cohorts. The indie-developer-and-creator buyer picks the Starter or Creator plan on the side-project, the prototype-and-demo, and the personal-creative voice-AI workflow. The startup-and-SaaS-team buyer picks the Pro or Scale plan on the in-product voice-AI feature embed workflow including the customer-support-voice-agent, the in-app-voice-feedback, and the voice-onboarding flow. The mental-health-and-coaching-app buyer picks the Pro or Scale plan on the expressive-voice-narration and the emotion-aware-conversation workflow that the Hume positioning specifically calls out (mental-health applications, expressive narration, character voices with consistent affect). The character-voice-and-game-studio buyer picks the Scale or Business plan on the consistent-character-voice-affect across the multi-character production workflow. The enterprise-customer-experience buyer (the customer-support, the IVR-replacement, the voice-assistant) picks the Business or Enterprise plan on the production-deployment with the volume-tier per-minute rate.

Hume AI Offer Types and Discount Tiers

The Hume AI coupons listed on the coupon page cluster into seven recurring offer types. Knowing which type applies to your cart helps pick the right code at checkout rather than trying every listed code in trial and error. The active codes refresh as the merchant launches new sale windows.

• Free plan with 10,000 characters per month (Free 10,000 characters per month on TTS plus limited EVI usage): Hume AI offers a Free plan with 10,000 characters per month on Octave TTS plus limited EVI usage suited to the evaluation, the prototype, and the side-project workflow. The Free plan does not require credit-card input at signup and supports the maiden-evaluation of the voice-quality, the emotion-control, and the API-integration workflow before committing to a paid subscription.
• Starter plan at USD 3 per month (USD 3 per month for incremental usage and basic feature access): Hume AI Starter plan at USD 3 per month is the entry-tier paid plan suited to the indie-developer, the student, and the side-project-creator on the basic voice-AI workflow. The plan covers a higher monthly usage allowance than the Free plan and a basic-feature-access bracket on Octave TTS and EVI.
• Creator plan at USD 14 per month with commercial licence (USD 14 per month including commercial licence and team seats): Hume AI Creator plan at USD 14 per month suits the indie-developer-and-creator buyer with the commercial-licence path which permits the use of the generated voice in revenue-generating products and content.

Suits the in-product voice-feature embed workflow at the production-evaluation stage.
• Scale plan at USD 200 per month for production deployment (USD 200 per month with production-deployment usage and team seats): Hume AI Scale plan at USD 200 per month suits the production-deployment workflow with the higher-volume Octave TTS and EVI API usage, the higher RPM limits, the team-seat allocation, and the production-priority access. Suits the SaaS-team, the mental-health-coaching-app, and the character-voice-studio buyer on the production-stage workflow.
• Business plan at USD 500 per month for enterprise evaluation (USD 500 per month with enterprise-evaluation-tier usage and advanced features): Hume AI Business plan at USD 500 per month suits the enterprise-evaluation-and-mid-market deployment workflow with the larger usage allowance, the priority-API-access, the advanced feature-set, and the team-seat allocation. Suits the mid-market customer-experience and the enterprise-pilot buyer cohort.
• Enterprise plan with custom pricing and volume discounts (Custom pricing with volume-tier rate as low as USD 0.02 per minute on the EVI API): Hume AI Enterprise plan carries custom pricing on the dedicated-sales-contact workflow with the volume-tier rate. EVI API pricing can land as low as USD 0.02 per minute on the highest-volume application versus the standard EVI 2 USD 0.072 per minute rate. Suits the high-volume customer-support, the IVR-replacement, the voice-AI-product-line, and the enterprise-deployment buyer.

Stacking rules to remember: the welcome code does not stack with sitewide percentage codes, prepaid order discounts stack on top of the active code on UPI and card payments, free shipping above the threshold runs automatically when applicable, and bank or card offers apply on the final billing amount after the coupon-code discount has been applied.

Categories and Catalogue Breakdown at Hume AI

The Hume AI catalogue covers a focused range of categories suited to its target buyer. Each category carries its own typical discount depth and bundle pricing pattern. Here is a category-by-category breakdown with the pricing band and the offer profile.

Empathic Voice Interface (EVI 3) Conversational Voice AI

The EVI 3 category covers the latest empathic voice interface that can speak expressively with any voice (real or designed) without fine-tuning, available through the Hume API. EVI 3 is the first speech-language model with this capability and supports the conversational voice-to-voice workflow with the emotion-aware response generation, the optimised-for-user-satisfaction speech output, and the end-of-turn detection. Suits the conversational-voice-AI use case across customer-support, voice-assistant, character-voice, and in-product voice-feedback workflows.

Octave Text-to-Speech (Octave TTS)

The Octave TTS category covers the text-to-speech model that understands the meaning of what it is saying with the ability to generate custom AI voices with adjustable emotions. Octave's outputs were rated favourably over ElevenLabs Voice Design in a blind comparison study with 180 human raters on audio quality (71.6 percent), naturalness (51.7 percent), and prompt-matching to the desired voice description (57.7 percent). Pricing is roughly half of the ElevenLabs equivalent service. Suits the narration, the audiobook, the podcast-voice, the character-voice, and the in-product voice-output workflow.

Expression Measurement API (Audio, Video, Text)

The Expression Measurement API category covers the multimodal APIs that measure hundreds of dimensions of human expression across audio (vocal expression and prosody), video (facial expression), and text (emotional valence and arousal). This product line distinguishes Hume from the TTS-focused competitor stack and supports the emotion-research, the customer-experience analytics, the mental-health-screening, and the user-research workflow.

Custom Voice Cloning and Voice Design

The Custom Voice Cloning and Voice Design category covers the rapid-custom-voice-creation workflow on EVI 3 and Octave TTS that lets the buyer design a custom voice from a text-description (voice design) or generate from a short audio sample (voice cloning). The custom voice can carry an adjustable-emotional-affect and serve as a brand-voice across the customer-touchpoint stack. Available across Creator, Pro, Scale, Business, and Enterprise tiers.

Conversational Voice Agent for Customer Support

The Conversational Voice Agent for Customer Support category covers the EVI-3-based voice-agent deployment for the inbound and outbound customer-support workflow with the emotion-aware response generation, the empathic acknowledgement, and the end-of-turn detection. Suits the customer-support-team, the IVR-replacement, and the voice-bot deployment on the SaaS-platform-or-mobile-app product. Production-deployment requires the Scale, Business, or Enterprise tier.

Mental Health and Coaching App Voice Layer

The Mental Health and Coaching App Voice Layer category covers the emotion-aware voice-AI integration for the mental-health-app, the coaching-app, the meditation-app, and the journaling-app workflow. The Hume positioning specifically calls out mental-health applications as a primary target use case for the empathic voice-AI capability. The product-stack supports the emotion-detection, the empathic-response generation, and the user-state-aware conversation workflow.

Character Voice for Games and Interactive Media

The Character Voice for Games and Interactive Media category covers the consistent-character-voice-affect across the multi-character production workflow for games, animation, interactive-fiction, and AR-VR. The expressive-speech and the consistent-emotional-affect across the character-arc-and-scene support the production-grade character-voice workflow. Available across Pro, Scale, Business, and Enterprise tiers.

API and SDK for Developer Integration

The API and SDK category covers the REST API for EVI 3, Octave TTS, and Expression Measurement plus the WebSocket connection for real-time voice-to-voice workflow, plus the JavaScript SDK, the Python SDK, the React SDK, the iOS SDK, and the Android SDK for the developer-integration workflow. Suits the startup-developer, the SaaS-team, the indie-developer, and the agency-developer buyer cohort.

Bank, Card, and UPI Payment Offers

Indian banks run instant discount, EMI conversion, and cashback offers on the Hume AI checkout during major sale windows. Stacking a bank offer on top of the active coupon code is the standard path to the deepest effective discount.

• International credit and debit card payment: Hume AI accepts Visa, MasterCard, American Express, and Discover credit-and-debit cards on the subscription billing workflow. The 3D-Secure-OTP-verification path runs on the Indian-issued international-enabled credit-card on the cross-border SaaS-subscription transaction.
• Annual billing for cash-flow stability: Hume AI supports the annual-billing-cycle path on the Starter, Creator, Pro, Scale, and Business plans which stabilises the per-month cost against any mid-year price adjustment. The annual-payment runs on the year-1 commitment with the renewal at the end-of-the-year on the auto-renewal workflow which the workspace-admin can disable from the billing settings.
• GST and Indian-tax-compliance invoicing: Hume AI issues the standard SaaS-subscription invoice with the company-billing-name and the subscription-detail. The Indian-buyer should account for the equalisation-levy or the import-of-services GST per the Indian tax-framework on the international SaaS-subscription import workflow.
• Enterprise plan invoicing on the custom-quote workflow: Hume AI supports the corporate-billing-and-purchase-order workflow for the Enterprise-tier organisation through the dedicated-sales-contact path. The custom-billing-cycle (monthly, quarterly, annual), the credit-period, and the purchase-order-acceptance run on the negotiated terms with the Hume AI sales team. The volume-tier per-minute rate on the EVI API can land as low as USD 0.02 per minute on the highest-volume application.
• USD-denominated subscription pricing: Hume AI prices subscription and API usage in USD which means the Indian-buyer should monitor the INR-USD exchange-rate during the year-long subscription cycle. The annual-billing-discount provides a partial-hedge against the mid-year FX fluctuation versus the monthly-billing path.
• Pay-as-you-go API usage above the plan-tier allowance: Hume AI supports the pay-as-you-go usage above the plan-tier monthly allowance on the EVI API and the Octave TTS API at the standard per-minute or per-character rate. The pay-as-you-go billing runs on the same payment-method on file at the end of the monthly billing-cycle.
• No India-specific UPI or net banking path on the subscription checkout: Hume AI does not currently support the Indian-domestic UPI or net banking on the subscription checkout. The Indian-buyer should use the international-card payment route for the subscription transaction.
• Refund and prorated cancellation policy: Hume AI supports the prorated cancellation refund on the unused subscription window per the standard SaaS-refund policy. Read the refund policy on the Hume AI terms-of-service page before committing to the annual-billing cycle.

Bank offer eligibility, minimum cart values, and discount caps vary by sale window. Read the bank offer terms on the Hume AI cart page before confirming the payment. UPI offers via NPCI are typically separate from card offers and can stack with both the sitewide code and the card offer where applicable.

Service Policies and Workflows

Understanding the service policies before placing the order avoids surprises later. Here is the policy framework for Hume AI.

• Free plan and evaluation workflow: Hume AI offers a Free plan with 10,000 characters per month on Octave TTS plus limited EVI usage suited to the maiden-evaluation, the prototype, and the side-project workflow. The Free plan does not require credit-card input at signup and supports the maiden-evaluation of the voice-quality, the emotion-control, and the API-integration workflow before committing to a paid subscription. The Hume Playground supports the rapid-prototype-and-iterate workflow for voice-design, emotion-control, EVI-conversation-flow, and Expression-Measurement testing.
• Annual billing discount and renewal workflow: Hume AI supports the annual-billing-cycle path on the Starter, Creator, Pro, Scale, and Business plans which stabilises the per-month cost against any mid-year price adjustment. The annual-billing cycle starts on the subscription-commitment date and renews on the same date the next year on the auto-renewal workflow which the workspace-admin can disable from the billing settings. The Enterprise plan carries custom pricing on the annual workflow.
• API key and usage management: Hume AI generates the API keys on the Hume Dashboard for the developer-integration workflow. The API key is used in the REST API, WebSocket connection, and the SDK initialisation across JavaScript SDK, Python SDK, React SDK, iOS SDK, and Android SDK. The usage-and-billing dashboard tracks the per-API-call consumption against the plan-tier allowance. The API key can be rotated and revoked from the dashboard on the security-incident workflow.
• Pay-as-you-go above plan-tier allowance: Hume AI supports the pay-as-you-go usage above the plan-tier monthly allowance on the EVI API and the Octave TTS API at the standard per-minute or per-character rate. The pay-as-you-go billing runs on the same payment-method on file at the end of the monthly billing-cycle. The usage-alert and the soft-cap configuration are available on the dashboard to prevent the runaway-usage-billing scenario.
• Data privacy and content policy: Hume AI runs the data-encryption-in-transit and the data-encryption-at-rest as standard across every plan tier. The audio-and-text-input data submitted through the API is governed by the Hume AI Privacy Policy and the Terms of Service. The voice-cloning workflow requires the buyer to have the necessary rights and consent for the source-voice. The character-voice and the commercial-licence rights are scoped to the Creator, Pro, Scale, Business, and Enterprise tiers.
• SDK, documentation, and developer support: Hume AI offers the comprehensive SDK across JavaScript, Python, React, iOS, and Android plus the REST API and the WebSocket connection for the real-time voice-to-voice workflow. The Hume Documentation, the API Reference, the example-app starter-kit, the Hume Playground, and the developer-community Discord channel support the developer-integration workflow. The dedicated-customer-success-manager assignment runs on the Enterprise-tier.
• Cancellation and refund policy: Hume AI supports the subscription cancellation through the billing-page workflow with the disable-auto-renewal toggle. The monthly billing cycle stops at the end of the current billing month on the cancellation-confirmation. The annual billing cycle supports the prorated cancellation-refund on the unused subscription window per the standard SaaS-refund policy. Read the refund policy on the Hume AI terms-of-service page before committing to the annual-billing cycle.

How It Compares With Competitors

Hume AI competes in the voice-AI and text-to-speech and emotion-AI category against the broader brand stack including ElevenLabs (the US-origin TTS leader on quality and voice-cloning), OpenAI TTS (the OpenAI text-to-speech with instructable-voice-character positioning), Cartesia (the US-origin real-time TTS), PlayHT (the US-origin TTS for narration and audiobook), Gemini TTS (the Google text-to-speech), Murf AI (the US-origin TTS for narration), Resemble AI (the Canada-origin voice-cloning), WellSaid Labs (the US-origin TTS for corporate narration), Speechify (the US-origin TTS for audiobook), Descript (the US-origin podcast-and-video editor with voice cloning), Synthesia (the UK-origin AI-video with voice), HeyGen (the AI-video with voice), Wavel AI, plus the conversational-voice-AI stack covering Synthflow AI (the Berlin AI voice-agent SaaS), Retell AI, Vapi AI, Bland AI, Air AI, Cresta AI, Replicant, PolyAI, Sierra AI (the Bret Taylor company), Cognigy, Kore.ai, Yellow.ai, Haptik, plus the Indian voice-AI stack including Smallest.ai (the Bengaluru sub-10B-parameter voice-AI), Sarvam AI (the Bengaluru USD 41M voice-AI), Dubverse, Vernacular.ai (now Skit.ai), Slang Labs, and the broader open-source-and-self-hosted stack including Coqui TTS, Tortoise TTS, Bark, OpenVoice, F5-TTS, plus the platform-stack from AWS Polly, Google Cloud Text-to-Speech, Microsoft Azure Cognitive Services Speech, IBM Watson Text to Speech. The brand differentiates on the Dr-Alan-Cowen founder-led New-York-City-headquartered semantic-space-theory-research-pedigree, the USD 50 million Series B funding from EQT Ventures and Union Square Ventures and Nat Friedman and Daniel Gross and LG Technology Ventures, the empathic-voice-interface positioning specifically for mental-health and expressive-narration and character-voice-with-consistent-affect use cases, the EVI 3 first-speech-language-model-with-any-voice-without-fine-tuning capability, the Octave-TTS first-text-to-speech-system-that-understands-what-it-is-saying positioning, the Octave-vs-ElevenLabs blind-comparison study showing 71.6 percent audio-quality preference and 57.7 percent prompt-match preference, the Octave-pricing-at-roughly-half-the-ElevenLabs-equivalent-rate, and the seven-tier pricing structure spanning Free, Starter USD 3, Creator USD 14, Pro USD 70, Scale USD 200, Business USD 500, and Enterprise custom with the volume-tier as low as USD 0.02 per minute on the highest-volume EVI deployment.

Coupon Not Working: Troubleshooting

Codes occasionally fail to apply at the Hume AI checkout. Walk through this checklist before assuming the code is dead.

• Check the cart minimum. Most Hume AI codes require a cart value of Rs 299 to Rs 1,00,000 depending on the code. Add one more line item if you are just under the threshold.
• Confirm the category eligibility. Welcome codes target the full catalogue but some category-specific codes apply only to selected ranges. The coupon card details the scope.
• Verify the user eligibility. Welcome codes work only for first-time buyers on the registered account. A repeat buyer trying a welcome code will hit a usage block.
• Confirm the expiry window. Codes carry expiry dates. The coupon card flags expiring-soon codes with an orange tag.
• Check payment method restrictions. Prepaid order discounts require UPI, net banking, or card payment. COD orders will not trigger the prepaid stack.
• Refresh the page or restart the cart. Sometimes the cart session times out. Refreshing or clearing the cart and rebuilding it can reset the eligibility check.
• Look for a bank offer overlap. Bank instant discount offers occasionally conflict with sitewide percentage codes. Try the bank offer or the coupon code separately to see which path gives the deeper effective discount.
• Reach Hume AI support. If the code is listed as verified but consistently fails, contact Hume AI customer support through the site chat or email with the screenshot. Support typically responds within 24 hours on weekdays.

Verdict

Best for

Indie-developer-and-creator buyers picking the Starter or Creator plan on the side-project, the prototype-and-demo, and the personal-creative voice-AI workflow, startup-and-SaaS-team buyers picking the Pro or Scale plan on the in-product voice-AI feature embed workflow including the customer-support-voice-agent and the in-app-voice-feedback and the voice-onboarding flow, mental-health-and-coaching-app buyers picking the Pro or Scale plan on the expressive-voice-narration and the emotion-aware-conversation workflow that the Hume positioning specifically calls out, character-voice-and-game-studio buyers picking the Scale or Business plan on the consistent-character-voice-affect across the multi-character production workflow, and enterprise-customer-experience buyers picking the Business or Enterprise plan on the production-deployment with the volume-tier per-minute rate (as low as USD 0.02 per minute on the highest-volume application).

Be careful if

Welcome-credit and trial-extension codes work only for new accounts not on the existing-paid-subscriber path. The Free plan covers a 10,000-characters-per-month TTS allowance plus limited EVI usage which fits the prototype workflow but will exhaust quickly on the production-deployment workflow. The Indian-buyer should account for the equalisation-levy or the import-of-services GST per the Indian tax-framework on the international SaaS-subscription import workflow. Hume AI does not currently support the Indian-domestic UPI or net banking on the subscription checkout which means the Indian-buyer should use the international-card payment route. The subscription pricing is denominated in USD so the Indian-buyer should monitor the INR-USD exchange-rate during the year-long subscription cycle. The voice-cloning workflow requires the buyer to have the necessary rights and consent for the source-voice. EVI 3 pricing is TBA at the time of publication so the production-budget-planning buyer should confirm the per-minute rate with the Hume sales team before the production-deployment commitment.

Best saving move

The single deepest saving move on Hume AI is to start on the Free plan to validate the voice-quality and the API-integration workflow on a maiden-prototype, then commit to the annual-billing cycle on the Pro or Scale plan once the production-readiness criteria are met for the saving on the per-month cost through the GrabOn-listed coupon path. For the high-volume customer-support or the IVR-replacement deployment, the deepest move is the Enterprise-tier custom-quote workflow with the volume-tier per-minute rate (as low as USD 0.02 per minute versus the standard EVI 2 USD 0.072 per minute rate) on the dedicated-sales-contact path. For the indie-developer-and-creator on the commercial-monetisation workflow, the deepest move is the Creator plan at USD 14 per month with the commercial-licence path that permits the use of the generated voice in revenue-generating products and content.

What is the difference between Hume AI EVI 3, Octave TTS, and Expression Measurement API?

Hume AI offers three primary product families. EVI 3 (the Empathic Voice Interface) is the latest version of the conversational voice-to-voice AI system powered by an empathic large language model that knows when the user is finished speaking and generates vocal responses optimised for user satisfaction. EVI 3 is the first speech-language model that can speak expressively with any voice (real or designed) without fine-tuning. Octave TTS is the first text-to-speech system that understands what it is saying with the ability to generate custom AI voices with adjustable emotions. The Expression Measurement API measures hundreds of dimensions of human expression across audio, video, and text which distinguishes Hume from the TTS-focused competitor stack.

What is the Hume AI pricing structure for developers?

Hume AI offers seven primary plans. The Free plan covers 10,000 characters per month on Octave TTS plus limited EVI usage. The Starter plan is USD 3 per month for incremental usage.

How does Hume AI Octave TTS compare with ElevenLabs?

In a blind comparison study with 180 human raters, Octave outputs were rated favourably over ElevenLabs Voice Design on audio quality (71.6 percent), naturalness (51.7 percent), and how well the generated speech matched the prompt-description of the desired voice (57.7 percent). Octave pricing is roughly half of the ElevenLabs equivalent service. The emotion-and-expression positioning of Octave specifically targets the use case where the emotional register has to land precisely (mental-health applications, expressive narration, character voices with consistent affect). ElevenLabs holds the lead on consistent clean output for narration and on voice-cloning depth across the competitor stack.

Does Hume AI offer SDKs for developer integration?

The Python SDK supports the data-science and the backend-integration workflow. The React SDK supports the front-end React-app voice-component workflow. The iOS SDK supports the native-iOS-app voice-integration workflow. The Android SDK supports the native-Android-app voice-integration workflow.

The Hume Documentation, the API Reference, the example-app starter-kit, the Hume Playground, and the developer-community Discord channel support the developer-integration workflow.

Can I clone or design a custom voice on Hume AI?

Yes, Hume AI supports rapid-custom-voice-creation through two paths. The voice-design path lets the buyer create a custom voice from a text-description on EVI 3 and Octave TTS without the source-audio sample. The voice-cloning path lets the buyer generate a custom voice from a short audio sample of the source-voice. The custom voice can carry an adjustable-emotional-affect and serve as a brand-voice across the customer-touchpoint stack. The voice-cloning workflow requires the buyer to have the necessary rights and consent for the source-voice. The character-voice and the commercial-licence rights are scoped to the Creator, Pro, Scale, Business, and Enterprise tiers.

What payment methods does Hume AI accept for Indian buyers?

Hume AI accepts Visa, MasterCard, American Express, and Discover credit-and-debit cards on the subscription billing workflow. The 3D-Secure-OTP-verification path runs on the Indian-issued international-enabled credit-card on the cross-border SaaS-subscription transaction. Hume AI does not currently support the Indian-domestic UPI or net banking on the subscription checkout which means the Indian-buyer should use the international-card payment route. The subscription pricing is denominated in USD so the Indian-buyer should monitor the INR-USD exchange-rate during the year-long subscription cycle. The Enterprise tier supports the corporate-billing-and-purchase-order workflow through the dedicated-sales-contact path with the custom-billing-cycle and the credit-period workflow.
