Best WhatsApp Business API Platform for Indian SMBs (2026)

The case for

• Pricing is published in rupees and the platform fee starts at 2,500 rupees a month, so an Indian SMB budgets without a sales call.
• Getting the WhatsApp Business API itself carries no platform charge, and service replies inside the 24 hour customer window stay free.
• Annual billing takes the chatbot builder plan to 2,250 rupees a month, a straight 10 percent cut with no seat minimum.

The catch

• The platform fee is only part of the bill, since Meta charges 1.09 rupees per marketing message and 0.145 per utility message to Indian numbers.
• Conversation credits are prepaid and non-refundable, so an unused balance or a misfired campaign spend does not come back.
• Meta bills per delivered template message (since 1 July 2025), and from 1 October 2026 it also charges service replies after 1,000 free per number a month, which raises the cost of chatty campaigns.

The case for

• Growth at ₹2,799 a month includes unlimited agent seats, so growing the support team does not change the subscription line
• Service conversations carry no template charge, so inbound customer replies within the service window cost nothing beyond the plan fee
• Interakt is owned by Jio Haptik and prices in rupees, so Indian buyers get a domestic GST invoice rather than a dollar card charge

The catch

• Interakt's own table lists per message template rates on Growth and Advanced but says Enterprise has no markup charges, confirming lower tiers carry one
• The real bill is subscription plus template charges above the free limit, so a marketing heavy month costs well beyond the ₹2,799 headline
• Every plan price is quoted plus taxes, so 18 percent GST lands on top of the ₹2,799 or ₹3,799 monthly figure

The case for

• Gallabox is a Chennai based company that publishes INR pricing, so Indian buyers pay in rupees rather than carrying forex markup on a USD invoice
• WhatsApp conversation charges are passed through at Meta rates with minimal markup, so message spend stays auditable against Meta published country rates
• Plan prices, included seats and per extra user rates are all published, so you can model a 12 agent rollout before contacting sales

The catch

• The Basic plan hard caps at 3 users with no seat add-on, so a fourth agent forces the jump to Essential at ₹5,599 a month
• Extra users cost ₹1,200 a month on Essential and ₹1,500 on Advanced, so seat growth outruns the plan fee quickly
• Meta has charged per delivered template message since July 2025, so broadcast spend bills separately and routinely dwarfs the subscription itself

The case for

• Pricing is published in rupees at ₹3,000 a month for five agents, which is rare among Indian WhatsApp API resellers
• Onboarding covering Facebook business verification and WhatsApp number registration is included free rather than billed as a separate setup project
• GST is stated up front at 18 percent on the plan price, so the invoice total matches what the pricing page implies

The catch

• Plans are billed yearly only, so the ₹3,000 monthly figure is a twelve month commitment settled as one annual invoice
• Meta conversation charges are billed on top of the plan, and the page does not disclose whether a markup is applied to them
• Starter bundles five agents and Pro ten, with each additional agent reported at around ₹500 a month beyond the included count

The case for

• Zoko passes Meta conversation rates through without a markup on the Plus, Elite and Max plans, so you pay WhatsApp rate card plus the flat fee
• The Starter plan at 49.99 dollars a month lets you add unlimited agents for free, which suits a small team fielding chats
• Eleven prebuilt ecommerce flows including abandoned checkout recovery and COD double confirmation are free on every plan, with 500,000 flow steps included each month

The catch

• Everything is prepaid. The monthly subscription is charged on day one of the billing period and you then top up credits before any conversation runs
• Zoko issues no refunds at all except for a positive prepaid balance when you close the account, and promotional credit is never refunded
• The 49.99 dollar Starter plan marks up every conversation to 0.015 dollars, so heavy senders pay far more than the 79.99 dollar Plus plan costs

The case for

• States explicitly that it is not a Meta BSP, rather than implying official status
• Publishes both monthly and full annual figures in rupees, so the annual saving is verifiable rather than advertised
• Razorpay and Cashfree payment links and Cal.com booking are native, not webhook homework

The catch

• Meta bills WhatsApp conversations separately, so the subscription is a floor and not the total cost
• The entry plan starts at Rs 2,999 a month, well above the Rs 199 to Rs 999 band common in India SMB tooling
• Whether the rupee figures include GST is left unsaid on the pricing page, leaving an 18% gap in any cost comparison
