- Early access to the sandbox, the full API reference and Unify Agents (MCP).
- A named engineer from the Technology Center for your first integration.
- Roadmap influence. Your platforms and objects move up the queue.
- Design-partner pricing, agreed up front and held for the first year.
Finance questions.
Which accounting systems do you cover?
The Accounting API is designed for QuickBooks Online and Desktop, Xero, NetSuite, Sage Intacct, Microsoft Dynamics 365 Business Central, FreshBooks, Zoho Books and more. Each integration page shows its current status, and the coverage matrix shows object-level read and write.
What about QuickBooks Desktop?
QuickBooks Desktop needs a small connector your customer installs once. The QuickBooks Desktop integration page shows its current status.
How do you handle multi-currency and multi-entity books?
Every amount carries its currency, and ERP objects carry subsidiary or entity ids. Exchange rates come from the source ledger, never recalculated by us.
Can we post journal entries?
Where the platform allows it, yes, with validation of accounts and periods before submit. Closed periods are rejected with a typed error.
How fresh is the data?
Sync-and-store objects refresh on a schedule you set per object, and webhooks fire on change. Pass-through reads are live.
