Why send invoices on WhatsApp?
98% Open Rate
WhatsApp messages are read within minutes. Compare that to email where 70-80% of invoices go unopened or land in spam folders.
Instant Delivery
Invoices arrive in your customer's WhatsApp chat in seconds. No spam filters, no promotions tab, no delays.
Read Receipts
Blue ticks confirm when your customer has seen the invoice. No more wondering if they received it.
2B+ Users Worldwide
WhatsApp is the most popular messaging app globally. Your customers already use it daily, especially in Asia, Africa, and Latin America.
Step-by-Step Setup Guide
Set Up WhatsApp Business Account
Download WhatsApp Business and register your business phone number. Then apply for API access through a Business Solution Provider (BSP) like Twilio, 360dialog, or MessageBird. This gives you programmatic access to send messages.
Complete Business Verification
Verify your business through Meta Business Manager. Upload your business registration documents and verify your phone number. This process typically takes 2-5 business days and unlocks higher messaging limits and the ability to use custom message templates.
Create Invoice Message Templates
In your BSP dashboard, create message templates for invoice delivery and payment reminders. Include variables for invoice_number, amount, and due_date. Templates must be approved by WhatsApp, which takes 1-2 business days.
Connect to Online Invoice Maker
Log in to your dashboard, go to Settings → Integrations → WhatsApp. Enter your BSP API credentials, select your approved message templates, and configure your sender phone number. Click Save & Verify.
Send Your First WhatsApp Invoice
Create or open an existing invoice, click Send, and choose WhatsApp as the delivery method. Enter your customer's phone number (with country code). They will receive the invoice summary and PDF attachment directly in their WhatsApp chat within seconds.
