What is Busy software integration?
Busy software integration connects Busy accounting with other systems such as ecommerce, CRM and sales apps so invoices, parties and items sync without retyping. Because Busy's integration options vary by version, Stack18 confirms what is supported first and uses supported import and export methods.

Busy Software Integration questions.
Does Busy have an API?
Integration options depend on your Busy version and set-up. We confirm what is supported in discovery and use supported import and export methods.
Is it safe for our books?
We validate data before posting, test on a copy and agree a go-live and rollback approach with your accountant.
Can we move from Busy to another system later?
Yes. We design with clean masters and mappings so migration stays possible.
Do you integrate Tally as well?
Yes. See our Tally integration page for that approach.
Who maintains the integration?
You own it. We provide documentation and can support it annually.
