hello what should I do if I have a customer invoice that is spread over 12 months and that in my old legacy system I recognized 3 months. How should I do in netsuite for this history (we do revenue recognition at the invoice level)

are you saying that you have a $120 invoice, that you used to bill and recognize $40 per month and now you bill/recognized $10 per month?

no no the duration is the same , just how to explain to the system that 3 months have already been recognized?

oh. is this about data migration?

Yes

aah, fun! all you have to do is to upload only nine months left. Alternatively you can do the full 12 months transaction and then recognize 3 months and then reverse it with a JE, on invoicing side you want to also upload three invoices issued (and probably payments received)
