I'm the first to admit I should've checked this before now. In my defence I say I was preoccupied with getting a functioning payroll and same day super working.
My data was migrated across from Reckon Desktop. The starting point was 01/07/24. The first invoice should've been Inv00367 but the Reckon One data has it as Inv00370. It was corrected, if that's the right word, by renaming subsequent invoices. For example, what is, and should be, Inv00394 on 7/01/'25 is titled Inv00367 in Reckon One. Inv00411 became Inv00368 on 29/04/'25 and Inv00431 became Inv00369 on 16/09/'25. At least after that invoice numbers in Reckon One matched those recorded in Desktop.
Can I manually change the invoice numbers prior to 16/09/'25 so they match existing records?
