Zapier Integration: Automate Billed With 6,000+ Apps

Zapier is the connective tissue between apps that do not natively talk to each other. It works on a simple model: a trigger (something that happens) starts a Zap, and one or more actions (things Zapier then does) follow. For invoicing, the trigger is usually an event in Billed — a new invoice created, an invoice marked paid — or an event elsewhere that should create something in Billed, like a new client signing a contract.

The value is eliminating copy-paste. Most small businesses lose time moving the same data between tools: re-typing a new client into the invoicing app, manually pinging the team when a big invoice clears, updating a spreadsheet the accountant relies on. Each handoff is a few minutes and an opportunity to forget. A Zap does the handoff every time, instantly, without you remembering.

Because Zapier connects to 6,000+ apps, the integration is effectively open-ended. If a tool you use has a Zapier app — most do — you can wire it to your invoicing without waiting for a native integration to be built.

Start with the tasks you do most often, because those return the most time. A few high-value patterns:

Payment alerts: when an invoice is marked paid in Billed, post a message to a Slack or Teams channel so the whole team sees cash landing without checking the dashboard. Bookkeeping sync: when a payment is recorded, add a row to a Google Sheet or Airtable base your accountant uses, keeping a running ledger without manual export. Client capture: when a new deal closes in your CRM or a form is submitted, create the client record in Billed so it is ready to invoice. Follow-up tasks: when an invoice goes overdue, create a task in your project tool or a card in Trello to prompt a personal follow-up.

The discipline that matters: do not automate everything on day one. Pick one or two Zaps tied to a task you genuinely repeat daily or weekly, confirm they fire correctly, then expand. An automation you do not trust is worse than no automation.

You build Zaps in Zapier's visual editor, not in Billed. Create a Zapier account, start a new Zap, and choose your trigger app and event — for example, Billed as the trigger app and 'new payment' as the event. Connect your Billed account when prompted (Zapier walks you through authorizing it). Then add an action app — Slack, Google Sheets, your CRM — and map which fields go where, such as sending the invoice number and amount into the Slack message.

Test the Zap with a sample record so you can see exactly what the action produces before it runs live. Once it looks right, turn it on. From then, Zapier checks for the trigger automatically — in near real time on most plans — and runs the action without you touching either app.

No code is involved at any step; the entire flow is point-and-click. If you later need a multi-step Zap (one trigger, several actions, with filters or conditions), Zapier supports that on its paid tiers, but a single trigger-to-action Zap is enough to remove most repetitive admin.
