We are to migrate our legacy transactions such as invoices from our newly acquired subsidiary to NetSuite. Is it better to temporarily turn on Allow Override of the Auto-generated numbers, so that we can use the legacy document numbers in the Invoice No. field or is it better to store them in a custom field? We're asking because we realized that it affects our customer statements in NetSuite. If we store them in a custom field, then they don't show up by default in the customer statements (unless it's a custom field). If we turn on the Allow Override of the auto-generated numbers, then there's inconsistency. Just want to weigh the pros and cons especially the ones that we are not yet aware of.

If the numbering scheme of your newly acquired subsidiary is different from yours then I would recommend allowing override of invoice numbers and using the legacy number Or if that would cause duplicates then add a dash abbreviation to the end. That is usually pretty understandable to most companies

can you not set numbering to behave on a per sub basis and define the "start" number and just do the import and turn it on after you're done?

Thanks!
