Why integrate with FreeAgent
Common scenarios for SaaS companies building FreeAgent integrations for their customers.
Automate invoice creation from billing or CRM platforms
Subscription billing and CRM SaaS companies can automatically generate and mark invoices as paid in their users' FreeAgent accounts, eliminating manual double-entry and ensuring UK tax compliance stays up to date.
Sync expenses from spend management tools
Corporate card and expense management platforms can push categorized expense records directly into FreeAgent, mapped to the correct Chart of Accounts, so micro-business owners stop losing receipts and manually entering transactions.
Pull ledger data for advanced financial reporting
FP&A and advisory SaaS products can extract journal entries, account structures, and company info from FreeAgent to power cash flow forecasts, KPI dashboards, and scenario models that go far beyond FreeAgent's native reporting.
Keep customer and supplier records in sync across sales and finance
CRMs and field service platforms can sync contacts bi-directionally with FreeAgent so that customer records created by sales or operations teams are immediately available for invoicing without duplicates or stale data.
Map payroll and HR transactions to the correct ledger accounts
HR and payroll SaaS companies can fetch their users' Chart of Accounts from FreeAgent to accurately route salary, tax, and benefits entries to the right general ledger codes.

FAQs
Common questions about FreeAgent on Truto
Authentication, rate limits, data freshness, and everything else you need to know before you integrate.
What authentication method does FreeAgent use?
FreeAgent uses OAuth 2.0 for API authentication. Truto handles the full OAuth flow — including token refresh — so your end users connect their FreeAgent accounts without you managing credentials or expiration logic.
Which Unified APIs does Truto support for FreeAgent?
Truto maps FreeAgent to the Unified Accounting API (Accounts, Company Info, Contacts, Expenses, Invoices, Journal Entries) and the Unified User Directory API (Users). These unified models let you use the same schema across multiple accounting integrations.
Are there specific tools or proxy endpoints available for FreeAgent today?
FreeAgent does not have pre-built tools yet — they are built on request. Contact Truto to have any custom tool or proxy endpoint spun up for your specific workflow needs.
Does Truto handle FreeAgent's API pagination and rate limits?
Yes. Truto abstracts away pagination and rate-limit handling so you can fetch complete datasets — like a full contact list or journal entry history — without writing retry or cursor logic yourself.
Can I write data back to FreeAgent, or is it read-only?
The Unified Accounting API supports both read and write operations on supported models. You can create invoices, push expenses, and create or update contacts in FreeAgent through Truto's unified endpoints.
Is FreeAgent primarily suited for UK-based end users?
Yes. FreeAgent is heavily tailored to UK tax regulations including MTD for VAT and Self Assessment. It is offered free to NatWest, RBS, and Ulster Bank business customers, giving it deep penetration in the UK micro-SME market. If your users include UK freelancers, sole traders, or small limited companies, FreeAgent coverage is essential.
