At a glance
What the integration enables
Four use cases โ from immediate operational wins to long-term customer relationship building.
Digital receipts
Replace printed receipts
A customer pays, their WhatsApp number is on file, and the receipt lands on their phone within seconds. Reduces paper cost, reduces printer jams during peak hours, and gives the customer a permanent record.
Loyalty outreach
65โ85% message open rates
WhatsApp messages from opted-in businesses see open rates of 65โ85% โ 4โ5x higher than email. Your loyalty message actually gets read. A visit-based congratulation, a spend-milestone reward, a 'we miss you' after 45 days โ all triggered automatically.
Broadcast campaigns
Menu launches and promotions
New thali launched? Ramadan special menu? Live music Friday? Send a broadcast to your full opted-in customer list. KhanaOS customer data tells you who to target โ frequent lunch visitors, high-spend customers, customers who haven't tried a specific category.
Personalised CRM
Birthday, anniversary, milestone
Know a customer's birthday because you captured it at billing? Send a personalised WhatsApp offer in their birthday week. Anniversaries, visit milestones, spend thresholds โ automated, personal, and more effective than any blanket promotion.

App downloads needed
Customers already have WhatsApp
WhatsApp is where Indian consumers live โ it's the default communication channel for personal and business interactions. A loyalty programme built on WhatsApp meets customers where they already are, rather than asking them to download another app or check an inbox they've already tuned out.
Setup in 4 steps โ under 20 minutes
Connect WhatsApp Business API
Link your WhatsApp Business account via the KhanaOS integrations panel. You'll need a WhatsApp Business API provider โ KhanaOS supports Interakt and direct Meta API connections.
Configure message templates
Set up your receipt template, opt-in welcome message, and any loyalty trigger messages. WhatsApp requires pre-approved templates for business messages โ KhanaOS provides the standard templates.
Enable customer capture at billing
KhanaOS captures the customer's mobile number at the end of each transaction. Enable the WhatsApp opt-in trigger โ a message is sent to the number asking them to confirm opt-in.
Test and go live
Send a test receipt to your own number. Confirm the opt-in flow. Go live โ from this point, every transaction with a captured number triggers the receipt automatically.
