Signs you have outgrown the free app

One phone, five peopleThe business WhatsApp is on the owner's phone or a shared handset, so staff wait to reply and nobody knows who promised what to a customer.

Outstanding payments pile upAccounts staff call debtors one by one and forward ledger screenshots, while dues of 60 and 90 days grow.

Broadcast lists hit their limitsThe app's broadcast lists only reach people who saved your number, and sending to more risks the number being banned.

Questions about WhatsApp Business API for small and medium businesses

When should a small business move from the WhatsApp Business app to the API?

Move when several people need to reply from one number, when you want invoices and reminders sent automatically, when your broadcasts outgrow the app's lists, or when you run Click-to-WhatsApp ads at volume. A single owner replying to a few customers a day can stay on the app.

Can I send payment reminders to my buyers on WhatsApp?

Yes. Overdue reminders that state the invoice, amount and due date are utility templates. They can be sent automatically from your accounting data, with a payment link and an Already paid button that routes the reply to your accounts team.

Does MsgClub work with Tally?

MsgClub's plugins for Tally, BUSY, Marg and Google Sheets were built for SMS. Our team will confirm whether your version can also send WhatsApp invoices or reminders; if not, Zapier or a small script calling the API and webhooks connects your software.

What does WhatsApp API cost a small business?

You pay Meta's per-message rates for templates, by category, plus service replies beyond 1,000 a month per number under Meta's current pricing, and MsgClub's platform fee. There is no setup charge from Meta. Most SMEs start small and grow; see WhatsApp pricing for how to estimate it.

Can several staff use the same business WhatsApp number?

Yes. On the API, the number is used through the MsgClub team inbox, where each staff member has a login on the web panel or mobile app. Chats can be assigned, labelled and transferred, and the owner sees every conversation.

Will my number get banned for sending bulk messages?

Not if you use the official API, send approved templates only to opted-in customers and keep quality high. Bans usually come from unofficial bulk tools or many users blocking and reporting your messages. Meta also sets a messaging limit that rises as you send good-quality messages.
