“How to send an invoice via WhatsApp” is a high-intent search: you already have (or are about to create) the invoice and need the fastest delivery channel. Invoice Maker: Estimate Maker lets you share PDF invoices via WhatsApp, email, or SMS.
The simple method
Create or open your invoice in Invoice Maker: Estimate Maker, export/share as PDF, choose WhatsApp, pick the client chat, and send.
Send a WhatsApp invoice step by step
- Finish your invoice (client, items, tax, due date, payment instructions).
- Preview the template so totals and branding look right.
- Tap share / export and choose WhatsApp.
- Select the client conversation and send the PDF.
- Mark status later as paid when payment arrives.
Meet clients where they reply fastest
Email still matters—but many freelancers and contractors get faster replies on WhatsApp or SMS. Sharing a PDF invoice from your phone removes friction and shortens time-to-payment.
Combine WhatsApp sharing with unpaid/overdue tracking so you know who still needs a polite follow-up.
