We have several customers in our Sage 50 US edition, which we've been using since 2013.

ONE of the customers have many thousands of invoices, which is cause problems with our network client machines trying to work with that customer's invoices.

So the question is, how do you ARCHIVE INVOICES for ONE CUSTOMER?

Notes:

• We are NOT trying to troubleshoot the original issue - we've already spent 8+ hours with Sage support.
• This is not a networking question.
• This is not a licensing question.
• This IS a question about archiving old invoices for ONE customer.
• We JUST want to archive old invoices, without affecting reports.

Thanks in advance for the help.
