Worse, they were going to void the sales document after sending to the client, calculate the amount of the hold back, enter invoice 1 as 90% of the original and then enter invocie 2 as the 10%. Then if the client paid the full amount, apply the payment to both. Works but, lots of work - we are not talking about 1 invoice a day.
Not sure they had considered how they were going to deal with the potential they would never get the hold back paid - that would have been interesting as well, I am sure that there accountant (external) whose wonderful idea this was - would have figured out a complicated way to force that back to being a problem that the software is not capable of solving.
Sounds like an accountant who is not going to have such a fat cash account when it comes to this 'now clean audit'
Just saying.
