Sage Active is a cloud accounting platform by Sage for SMEs and accounting firms, available in France, Spain, and Germany. The platform supports invoicing, VAT handling, bank reconciliation, and financial reporting, with strong alignment to local compliance requirements across all three markets.
Integrate Sage Active alongside dozens of other accounting and ERP systems through Maesn Unified API.

































Sage Active does not provide a free sandbox directly. Maesn provides one at no additional cost, so you can start building and testing your Sage Active integration from day one.
Every Sage Active integration requires a mandatory post-authentication step to fetch and store the correct company identifier per tenant. Maesn handles this entirely during onboarding. No extra setup required on your side.
Building directly on Sage Active means learning GraphQL, Hot Chocolate conventions and complexity limits before writing a single line of business logic. With Maesn, you start with a clean REST API from day one.
Clockin helps small and mid-sized businesses digitize time tracking. From work hours to project times. User log everything via app or terminal, even offline, eliminating paper-based processes entirely.
"We use Maesn to successfully leverage integrations and partnerships as a key driver for lead generation and expansion into new markets and customer segments. By connecting Clockin to our customers' accounting systems, project data flows directly into their existing tools, ensuring a smooth, reliable data exchange with the systems they already use."

Sage Active uses cursor-based pagination. You cannot jump to specific pages. Maesn exposes standard offset-based pagination and handles all cursor traversal inthe backend.

Sage Active does not offer webhooks natively. Maesn fills this gap with synthetic webhooks, covering every object and every event in a normalized payload, consistent with every other system in your stack.
