There are certain transaction types that Sage Accounting does not allow us to convert. We try to create transactions in Sage Accounting that match as closely as possible the transactions in the original software, although sometimes we have to use a different transaction type.
One example is Xero’s prepayment transaction type.
It’s not possible for us to represent Xero prepayments in the same way they are in Xero.
We’re planning some improvements to this, but in the meantime, you are likely to see differences between Xero and Sage for the duration a prepayment remains unallocated. Allocating the prepayment does correct the balances from the date the allocation is made.
