Accounting sync should be debuggable

Accounting sync is where small assumptions become expensive. Category mapping, vendor matching, tax treatment, and reconciliation rules all need to be understandable.

When sync logic is hidden, debugging becomes a support process. When sync logic is visible, debugging becomes engineering work that can be reviewed, tested, and improved.

An open integration layer also makes it easier to support different accounting systems without forcing every team into the same workflow.

Parowin’s open-source positioning makes accounting sync part of the product surface developers can inspect instead of a black-box export.
