Accounting

Wave

Exchange accounting data with TPP.

Import / Export OnlyImport / Export

Wave's public developer API has been limited to invite-only/legacy partners in recent years.

How the connection works

Data moves between TPP and this service via file export/import rather than a live, continuous connection.

Wave no longer offers general public API access for new third-party integrations. TPP supports CSV/PDF import and export instead.

What syncs

Available via file exchange.

Wave doesn't offer a live connection, but you can move data in and out of TPP for it today.
