Talk to the Technology CenterAbout the Sage 50 integration
Sage 50 is Sage's desktop accounting software for small businesses in the UK, Ireland and North America. A desktop agent connects company data to the Unify Accounting API.
Sage 50 runs on the customer's own machine or network, and its local SDKs differ by edition (Sage 50 Accounts in the UK, Sage 50 in the US and Canada). Unify Int delivers it as a Technology Center build with an agent that reads accounts, customers, suppliers, invoices and payments on a schedule.

Why build Sage 50 on Unify Int
One data model
Sage 50 records arrive in the same Unify Graph shape as every other platform in the category, with the original record kept in raw.
Unify Connect
A white-label flow for your customers to authorize Sage 50. Tokens are stored and refreshed for you.
Custom fields and passthrough
Map Sage 50 custom fields per connection, and call any endpoint the model does not cover through passthrough requests.
Unify Monitor
Request logs, sync health and alerts for every Sage 50 connection, so support can see what happened.
