Square + DMHub: Automated WhatsApp Receipts for Businesses Worldwide

Paper receipts get crumpled, lost, or declined entirely. Email receipts have a 21% open rate on a good day. WhatsApp receipts? They sit right in the conversation thread where customers can find them months later, reply to reorder, or ask a question about their purchase.

When you connect Square to DMHub, every completed transaction can trigger an instant WhatsApp receipt. Here's how to set it up and why it matters more than you'd expect.

The Problem With Traditional Receipts

The average retail store prints 50-200 receipts per day. That's thermal paper with BPA coating going into pockets, purses, and trash cans. Email receipts seemed like the answer, but they created a new problem: customers don't want to give their email at checkout. The friction of spelling out an address while a queue builds behind you kills the experience.

Phone numbers are different. Most customers already have their number on file. And in markets like Brazil, India, and Nigeria, WhatsApp is the default communication layer. Asking "can we send your receipt on WhatsApp?" gets a yes 73% of the time.

How It Works

The flow is simple:

1. Customer pays at your Square terminal
2. Square sends the transaction data to DMHub via webhook
3. DMHub matches the customer's phone number to a WhatsApp contact
4. A formatted receipt message is sent instantly

The receipt includes the store name, date, items purchased, amounts, tax, total, and payment method. No app download, no email, no paper.

Setting Up WhatsApp Receipts

Create Your Receipt Template

In DMHub, go to Templates > New Template and build your receipt format:

``` Receipt from {{business_name}} Date: {{date}}

{{item_list}}

Subtotal: {{subtotal}} Tax: {{tax}} Total: {{total}} Paid via: {{payment_method}}

Thank you for your purchase! Reply HELP for support or REORDER to buy again. ```

Submit the template for Meta approval. Most receipt templates are approved within 24 hours since they fall under the "utility" category.

Configure the Automation

1. Go to Automations > New Automation
2. Trigger: Square Payment Completed
3. Action: Send WhatsApp Template (select your receipt template)
4. Enable Auto-match Customer to link Square customer profiles to WhatsApp contacts

Handle New Customers

For first-time buyers who aren't in your WhatsApp contacts yet, configure a fallback:

• Display a QR code on your countertop that says "Scan for digital receipts"
• When they scan and message you, DMHub automatically links their WhatsApp number to their Square profile
• All future receipts are sent automatically

Beyond the Receipt

The receipt is just the entry point. Once you're sending WhatsApp receipts, you can layer on:

• Review requests sent 2 hours post-purchase: "How was your visit today? Reply 1-5."
• Product recommendations based on purchase history: "Customers who bought X also loved Y."
• Loyalty updates with every receipt: "You earned 15 points. Balance: 230 points. 70 points until your next reward!"
• Reorder prompts for consumable products: "Running low on coffee beans? Reply REORDER for the same bag at 10% off."

A furniture store in Riyadh added a care guide link to every receipt. A salon in Mexico City includes the next appointment booking link. A gym in Singapore attaches the class schedule for the week.
