If your business gets more than 30 to 40 WhatsApp enquiries a day, the free WhatsApp Business App starts breaking down. One phone, one login, no automation, no team inbox, and broadcast lists capped at 256 contacts. The WhatsApp Business API (Meta's Cloud API) removes those limits, but it is not something you download. You need a Meta Business account, a verified business, an approved display name, approved message templates and a platform to actually send and receive messages.
Doing business in Kolkata
Kolkata is the commercial gateway to eastern and north-eastern India. Its economy rests on trading houses, jute and tea companies with offices around Dalhousie and Park Street, the Kolkata Port, engineering and steel firms, and a large IT and BPO presence in Salt Lake Sector V and New Town Rajarhat. Burrabazar is one of the largest wholesale markets in Asia for textiles, spices, hardware and stationery, supplying Bihar, Jharkhand, Assam and Bangladesh trade. The city has strong publishing, education, healthcare and cultural sectors, and the Durga Puja season drives major retail, apparel and sweets business every year. Bengali is the language of everyday commerce, Hindi is common among the trading community and English is used in corporate offices. Businesses tend to be relationship driven and value conscious, and WhatsApp has become the default channel for orders and customer service.
What Kolkata businesses use whatsapp business api for
- Burrabazar wholesalers taking repeat orders and sharing dispatch photos with retailers in Assam and Bihar on WhatsApp
- Schools and coaching centres in South Kolkata managing admissions enquiries and fee reminders through WhatsPilot
- New Town and Rajarhat developers using Siteboard to manage broker networks and follow up on site visits
- Sweet shops and apparel brands running Durga Puja pre-order campaigns with automated confirmations
WhatsApp Business API for Kolkata's key industries
Wholesale trading, logistics & distribution
Distributors and logistics companies use the WhatsApp Business API to replace the daily flood of 'where is my consignment' calls. Each booking generates a template with the docket number and a tracking link, and delivery confirmation arrives with the POD image. Wholesalers send updated rate lists and scheme circulars to retailers who opted in, and take orders as replies. A transporter integrates its TMS with WhatsPilot so status changes push automatically. Bulk broadcasts must respect Meta's quality rating; a wave of blocks drops the daily sending limit. Measure customer service call volume per hundred consignments, order value received through WhatsApp and payment collection turnaround from retailers.
IT companies, SaaS & startups
SaaS companies and startups connect the WhatsApp Business API for OTP delivery, onboarding nudges and renewal alerts, usually from their own backend through the WhatsPilot API. A product with a fourteen-day trial would send a welcome template on signup, a feature tip on day three, and a renewal reminder with a payment link on day twelve. Authentication templates cost less than marketing ones, so classify them correctly. Founders sometimes route transactional and promotional traffic through the same template category and lose the lower rate. Measure OTP delivery time, trial-to-paid conversion and support tickets raised on WhatsApp against email.
Agriculture, agri-trading & food processing
Agri-input traders, dairies and food processors use the API to reach farmers and collection-centre staff in regional languages. A dairy cooperative sends a daily fat-and-SNF slip with the payment amount to each pouring member, while a seed distributor sends sowing-season stock availability to dealers. Hindi or Marathi templates get approved just like English ones when submitted with a clear category. Payments to farmers appear as a utility template with the bank credit reference. Do not push pesticide promotions to farmer numbers copied from a mandi register without recorded consent. Results are tracked as fewer payment-related calls at the collection centre, dealer order response time and read rates per language.
How pricing works with AICLEX
There are two separate bills. Meta charges per conversation, and those charges are billed to the payment method attached to your Meta Business account, at Meta's published India rates. We do not add a margin on top of Meta. The second bill is the WhatsPilot platform: Starter at Rs 1,599 per month for a single number with chatbot, broadcasts and a shared inbox, or Business Pro at Rs 3,999 per month for multiple agents, advanced flows, API access and CRM integrations.
Onboarding and verification assistance is included with an annual WhatsPilot plan. Custom chatbot flows beyond the standard templates start at Rs 15,000 one-time. Every invoice is a GST invoice from Aiclex Solutions Pvt. Ltd. so you can claim input credit.
What the WhatsApp Business API actually is (and is not)
The API is a server-side connection to WhatsApp provided by Meta. There is no app screen to type in. Every message goes in and out through software, which is why you need a platform like WhatsPilot on top of it. That is also why it can do things the app cannot: unlimited agents on one number, chatbots, CRM integration, bulk template sends to lakhs of opted-in contacts, and webhook events for delivery and read status.
Two facts trip up most first-time buyers. First, one phone number cannot be on the WhatsApp Business App and the API at the same time. Moving to the API means deleting the app account for that number, so we usually recommend a fresh number or a landline for the API and keeping the old number on the app during transition. Second, Meta bills by conversation, not by message. A 24-hour window opens when you send a template or a customer writes to you, and everything inside that window counts as one conversation of that category.
- Marketing conversations: promotions, offers, festive greetings. Highest rate.
- Utility conversations: order confirmations, delivery updates, appointment reminders. Lower rate.
- Authentication conversations: OTP and login codes.
- Service conversations: replies inside the 24-hour window after a customer writes to you. Free text, no template needed.
How we serve Kolkata
AICLEX works with Kolkata clients through Zoom planning calls and WhatsApp coordination, with Bengali, Hindi and English bot journeys and UPI payment links built in. Traders serving the eastern states benefit from catalogue and order bots, while Sector V IT firms use our Zoom licensing and automated webinar workflows.
Why Kolkata businesses choose AICLEX™
We own the platform
WhatsPilot is built and maintained by our team in Greater Noida. When you need a feature or a fix, you talk to the people who write the code, not a reseller ticket queue.
Meta charges passed through at cost
Your conversation charges are billed by Meta at official rates. Our revenue is the platform fee, so we have no reason to push you into unnecessary marketing sends.
Verification done with you, not to you
We sit on a call, screen-share your Business Manager and fix document mismatches before submission, which is where most self-service applications fail.
Chatbots and calling under one roof
Because we also build AI chatbots and the Zonvo voice agent, your WhatsApp number can escalate to an automated Hindi or English call when a lead goes cold.

Do I get a GST invoice and where is my data stored?+
Yes, every payment to Aiclex Solutions Pvt. Ltd. comes with a GST invoice. Messages travel through Meta's infrastructure and are end-to-end encrypted between Meta and the customer. WhatsPilot stores your contact and conversation data on servers hosted in India, and you can export or delete it on request.
Can I use my existing WhatsApp number on the API?+
Yes, but the number must first be removed from the WhatsApp Business App or personal WhatsApp, and chat history does not migrate. Many clients keep the old number on the app for a month while a new number goes live on the API, then let the old one go. We help you plan the switch so customers are not confused.
