WhatsApp marketing for restaurants, built into your billing

Most restaurants never see the same customer’s number twice. SwaadBill saves it at billing, records whether the customer agreed to receive WhatsApp messages, and lets you send them an offer in one tap when business is slow.

Why WhatsApp works for a restaurant

Your customers already use WhatsApp every day, so an offer lands where they will actually see it. There is nothing to install and no new account to create. Because the number comes from the bill, the list builds itself while you do your normal work.

How the customer list is built

  • You add the customer’s mobile number on the bill.
  • A consent box records whether the customer agreed to receive messages from you. It is never ticked for you.
  • The customer gets their bill on WhatsApp as a PDF.
  • Only customers who agreed are ever included when you send an offer.

Send an offer in one tap

Write the message, choose a percentage or flat-amount discount, and send. Every offer gets its own short code. When the customer comes in, you type the code at billing and the discount is applied to the bill, with GST calculated on the reduced amount.

See what actually worked

For each offer you can see how many messages were sent and how many customers redeemed the code. That tells you whether a Tuesday-lunch offer brought people in, so you can repeat what works and drop what does not.

A nudge when sales dip

SwaadBill compares today’s sales so far with the usual pattern for the same time of day. If sales are well below normal, it alerts you and drafts an offer. Nothing is sent automatically. You read the draft, change it if you like, and tap send yourself.

Offers that restaurants send

  • Slow Tuesday? Flat 20% off today till 10 PM, with a code to show at the counter.
  • We missed you. Come back this weekend and get ₹100 off.
  • New on the menu. Try it this week.
  • Thank you for dining with us. Here is your bill.

Rules we follow

  • Messages go only to customers who agreed to receive them.
  • Offer messages use a template approved by WhatsApp, so they reach customers reliably.
  • You stay in control: no offer is sent without you tapping send.
  • WhatsApp charges per message, so offers use a prepaid message balance. Ask us for the current rates.

Questions people ask

Is it allowed to message customers on WhatsApp?

Yes, when they have agreed to receive messages. SwaadBill records that consent at billing and only sends offers to customers who gave it.

Do my customers need to install anything?

No. They receive the bill and offers in the WhatsApp they already use.

Can I send an offer to any phone number?

No. Only customers saved from your bills who agreed to receive messages. This keeps your list clean and your messages welcome.

Will customers see my restaurant’s name?

Yes. Each offer carries your restaurant’s name and the offer code, so customers know who it is from.

Does this replace my billing software?

No. It is part of SwaadBill’s billing app, so the customer list and the offers come from the same bills you already make.
