Frequently asked questions
Common questions about connecting Commas and FastBill.
Connect your Commas and FastBill accounts once, pick a trigger in one app and an action in the other, then map the fields so data flows automatically between them. [3]
Example: when Commas's "Watch Customers" fires, WEXTL can "Cancel an Invoice" in FastBill. Commas has 5 triggers (including Watch Customers, Watch Discount Codes, and Watch Events); FastBill has 33 actions (including Cancel an Invoice, Complete an Invoice, and Create a Contact). Add filters and transforms between steps when you need them. [1]
Yes — the integration works in both directions. Use each app's triggers to start a workflow and the other app's actions to update it. [2]
No. Commas-to-FastBill automations are built visually on the canvas. You can optionally add custom JavaScript with Functions when you need advanced logic. [4]
Yes. Trigger-based automations start the moment Commas (or FastBill) fires a new event — webhook-backed apps run within seconds, and polling-only apps re-check on a schedule you control. [7]
A first automation typically takes 5–10 minutes: connect each app's credential once, drop a trigger + action onto the canvas, map the fields, and turn the workflow on.
You can build your Commas + FastBill automation on a 3-day trial with every feature unlocked. Cancel anytime. For your protection, a small deposit is charged to your card when your trial starts. It counts toward your first payment and is non-refundable. [8]
