Good morning, 

We have recently implemented the accounting version of Odoo v13 for our company and so far so good, there is how ever a few questions that I need help with please. The go live date for Odoo was 1 September 2020 - all balances was imported from the previous accounting system. 

I have picked up an error whereby my TB and trade debtors amounts on 31Aug2020 doesn't match. 

A client paid on the 1st of September, but this was part of the opening balance and I match the payment to an open entry. when I extract the trial balance and debtors age at 31 Aug 2020 there is a difference of the amount the client paid on 1 Sept 2020. If I run the age for 1 Sept and TB for 1 Sept these amount are in balance.

I need help please to fix this that the total between age debtors and TB on 31.08.2020 is in balance?

Thank you, 

Liesl
