Questions about messaging for small and medium businesses

Which channel should a small business start with?

WhatsApp, if your customers already message you there, plus SMS for those who do not. Together they cover order updates, invoices and offers. Add an IVR when calls start going unanswered, and AI Voice when following up on leads or dues takes too much of your team's time.

Is bulk SMS still worth it for a small business?

Yes, for reach. SMS lands on every phone without an app, which makes it dependable for OTPs, order alerts and payment reminders. Promotional SMS needs DLT-registered templates and a numeric header, goes out only between 10 am and 9 pm and skips DND numbers.

Can we send messages from Tally or BUSY?

Yes. MsgClub has plugins for Tally, BUSY, Marg and Focus ERP, so invoices and payment reminders can go out from the accounting software you already use. Other systems connect through the API, webhooks, Google Sheets or Zapier.

Do we need a developer to get started?

No. You can upload contacts and send campaigns from the MsgClub web panel or mobile app, and use plugins or Google Sheets for simple automation. A developer helps only when you want your own software to trigger messages and calls through the API.

How do we keep messaging costs under control?

Match each message to the channel that does the job at the lowest cost. Under Meta's current pricing, WhatsApp service replies are free for the first 1,000 each month per business number, so encourage customers to message you first. Use SMS for short alerts and keep marketing to opted-in, segmented lists.

Does one account really cover every channel?

Yes. SMS, WhatsApp, RCS, IVR, voice broadcast, missed call and AI Voice run from one MsgClub account, with delivery and call reports in one place. You switch on only the channels you need, and each has its own setup, such as DLT registration for SMS or Meta approval for WhatsApp.
