Opening balances and masters are not imported as an opaque all-or-nothing operation.
With Fastbooks
The controlled result
Structured adoption exposes debit, credit, difference, blockers and readiness before canonical apply.
Demonstration sequence
Show the workflow from evidence to outcome.
A feature page should make the user action, product transformation, review decision and accounting consequence visible in order.
1
Select a representative opening workbook
2
Inspect parsed rows, blockers and debit-credit difference
3
Correct or explicitly resolve invalid rows
4
Apply through the canonical adoption owner
End on the retained accounting or review outcome, not on a decorative success screen.
Evidence gate
What must be proven before broad advertising.
Implementation is not the same as commercial proof. These checks define what representative validation must support.
Excel, XLSM and CSV representative files
Blocked-row and difference calculations
Safe apply and retry behavior
Opening reports agree after restart and restore
Fastbooks product doctrine
Prepare intelligently. Review explicitly. Keep one accounting authority.
Fastbooks may capture, classify and prepare work from different sources. Official numbering, posting, correction, reversal and reporting must still pass through the existing canonical owners and permission boundaries.
