If I change/ignore an invoice or bill in Float will it change data in my accounting platform? – Float

The short answer is no.

The flow of data between Float and your accounting platform is one way only. This means we can take data from your accounting platform but don’t send anything back.

As a result any changes you make in Float will remain in Float only and won’t alter the data that is held in your accounting software.

Changes that are made in your accounting software to the due dates or expected dates of bills and invoices will flow through to Float and overwrite any changes that have been made in Float.
