For our monthly management accounts I use exported data from our Customers and Suppliers to create our aged debtors and creditors, pushing unallocated credits and debits into the correct part of the aged report.  This can, and does, lead to some customers/suppliers ending up in both parts as there are unallocated invoices and payments (mostly because they have been forgotten to be matched - it is a useful tool in that respect).

I'm not sure it would be possible.  Sage holds the transactions of the memorandum sales/purchase ledgers (Customers/Suppliers) in the relevant control accounts.

What you are suggesting seems to be a double control account for [summarising] your memorandum sales/purchase ledgers - one which holds all the invoices and the other which holds all the payments, and then someway of removing (from the totals) those which are matched off; I know of no accounting software (or practices) which do this (in the nominal ledger), perhaps you know differently?

At year end we do a correction (for the accounts and auditors) by putting through correcting journals (on the last day of the financial year, which auto reverse on the following day at the start of the next financial year) moving supplier debits and customer credits from the relevant control account to the relevant BS nominal (and back again).

In my point of view, sage should do this automatically. Accounting rules must be respected. Simples as that! PA payment on account ( payment in advance ) should go through  asset account and the allocation as well. Aged report will be result of two accounts, one from trade creditors and other from supplier deposits in Asset(advance payments). On the other hand, same happens with deposits in advance from costumers, credit balance in liability. I think people from Sage should change that. The system is prepared to save our operational time not otherwise!

Hi Deyvis, appreciate your comments, I can see that you've submitted this to the ideas board as well, thank you.
