Invoicing

Send a WhatsApp invoice without leaving the chat

Build an invoice on any conversation and 3650HQ renders it as a PDF and sends it straight to the customer over WhatsApp, or as an email attachment if you're talking to them on Gmail or IMAP. No separate invoicing tool, no copy-pasting a price into a text bubble.

1
Build the invoice on the thread
Add line items, quantities and prices. 3650HQ tracks a sequential invoice number for your workspace.
2
3650HQ generates the PDF
A clean, branded invoice PDF is created automatically.
3
It's sent in the same chat
The customer receives it as a WhatsApp document (or email attachment), no new app or tool involved.

What invoicing does and doesn't do

3650HQ generates and sends the invoice PDF and tracks its status (draft, sent, paid, void). Getting paid on it is a separate, connected step: see how in-chat payment collection works.

Frequently asked

Can I send an invoice on WhatsApp?

Yes. Build an invoice on any thread inside 3650HQ, and it's rendered as a PDF and sent to the customer directly in WhatsApp.

Does 3650HQ have an invoice generator for Nigerian businesses?

Yes. Invoices use sequential numbering per workspace, support multiple line items, and are priced in your local currency.

Can the AI draft an invoice for me?

Yes. 3650HQ's AI agent can draft an invoice from a conversation, which you review before it's sent.

What happens after I send an invoice?

It moves from draft to sent, and once the customer pays, it's automatically marked paid. See 3650HQ's in-chat payment collection.
