Contract Signed → First Invoice
The gap between 'contract signed' and 'first invoice sent' is where revenue quietly leaks — days pass, you get busy, and cash that should be in motion sits still. This workflow closes that gap automatically: the moment an e-signature completes, it generates and sends the first invoice with the right terms and logs it.
The contract gets signed, you celebrate, and then the invoice waits days while you finish other work. Your cash flow starts later than it should, every single time.
Signature complete → invoice out, same minute. The client's momentum carries straight into payment, and nothing falls through.
How it works
- 1Catch the signature — A webhook fires when the e-sign tool reports the contract fully executed — the trigger to start billing.
- 2Build the invoice — Generates the first invoice via your invoicing API with the agreed amount, terms, and due date pulled from the deal.
- 3Send to the client — Delivers the invoice to the right contact immediately, while the signing moment is still fresh.
- 4Log to your records — Writes the invoice and deal details to your Sheet/CRM so finance and delivery stay in sync.

Questions
Which e-sign and invoicing tools does it work with?
Any that emit a 'completed' webhook and offer an API — DocuSign, PandaDoc, Dropbox Sign on one side; Stripe Invoicing, QuickBooks, or your billing API on the other. Map the fields once.
Can it handle deposits vs. full invoices?
Yes. Branch on the deal type to issue a deposit, a first milestone, or the full amount with the right terms.
What's it tested on?
Tested on n8n v1.58+. You bring your e-sign webhook and invoicing API credentials.
