From our users

After the first BAS

"I love the reconciliation and sample testing it does...how it brings to the front any weird supplier names used and you can bulk run BAS. Can get them going across all available clients at the same time instead of one at a time."

"Not having to pull reports from Xero, copy, paste and update spreadsheets is amazing. The dynamic job summaries, and bulk processing is changing our business. We have so much more capacity."

Questions

The things firms ask first.

No. Every reconciliation, check and calculation runs through deterministic rules. Same inputs, same output, every time — so when you sign off, you know exactly what was checked and you can prove it.
