n-FreshBooks Has a Real API. Most Businesses Never Need to Touch It Directly.
FreshBooks exposes a REST API that lets you read and write clients, invoices, expenses, time entries, and payments programmatically, along with an app store of prebuilt connectors for the common pairings, Gusto for payroll, Shopify and a handful of CRMs, Zapier for simpler trigger-based automations. For anything outside that standard set, a specific CRM, a bank feed, a project tool that isn't on the app store, the API is where we build the connection FreshBooks doesn't ship on its own.
What connects natively, and where the API takes over
FreshBooks' app store covers the common integrations well enough for most freelancers and small service businesses: Gusto for payroll, a short list of CRMs, Shopify for e-commerce invoicing, and Zapier for lighter no-code automation between FreshBooks and a few thousand other apps.
Once a business needs something the app store doesn't cover, a specific CRM Zapier only partially supports, a bank feed with mapping logic that's specific to how the business categorizes expenses, a project tool that needs two-way sync rather than one-off triggers, the work moves to FreshBooks' own REST API.
The API covers the core objects a business actually needs to automate around: clients, invoices, expenses, time entries, and payments, authenticated through OAuth. It's a real, documented API, not a workaround, which makes most of what we build here straightforward custom development rather than anything fragile.
What we build through FreshBooks' API
A CRM or project tool connected properly, not just triggered
When Zapier's trigger-based automation isn't enough, a CRM deal closing needs to create the client and sync changes both directions, for example, we build the two-way sync directly against the API.
Bank and payment feeds matched automatically
Payments collected through a processor FreshBooks doesn't reconcile with natively get matched back to the right invoice and marked paid, instead of someone checking two systems side by side.
What's not connected to FreshBooks right now?
A CRM, a bank feed, a project tool, an accounts-payable process: name what's still manual and we'll take a look at what the API can do about it.
Hit a wall with FreshBooks' app store or Zapier integrations?
If Zapier's one-directional triggers aren't enough and FreshBooks' app store doesn't list what you need, that's exactly the gap the API closes. Tell us what you're trying to connect and we'll say what a real build against it would involve. And if FreshBooks isn't where your integration gap actually is, that's fine too, n-frames builds on top of whatever invoicing or accounting platform a business runs.
