Will inactive customers and vendors convert from Sage 50 to QuickBooks?
Yes, inactive customers and vendors convert to QuickBooks, and you can decide whether to bring them over during the migration.
Yes. Inactive customers and vendors in Sage 50 carry over to QuickBooks in a Sage 50 to QuickBooks conversion, and QuickBooks keeps them marked inactive. You can also choose to leave them behind before the file is built, which many businesses do to keep the new list clean.
How inactive records come over
When we convert a Sage 50 company file, the customer and vendor lists are copied as they stand. A customer flagged inactive in Sage 50 arrives in QuickBooks as inactive, not as an active record. The flag is one of the list fields we map across, along with names, addresses, terms, tax codes, and open balances. Historical transactions stay attached to those names just as they were in Sage 50.
If a vendor or customer was never used but still sits in Sage 50, it converts too. We do not silently drop dormant records. If a name has no transactions and you no longer need it, we can omit it from the target file during the conversion. That requires a clean mapping, and it is worth doing for lists with hundreds of dead entries.
Deciding what to keep
QuickBooks has its own “inactive” check box on each customer and vendor. After a conversion, a converted inactive record appears with that box checked in the QuickBooks list. You can still view it by toggling the list to show inactive names, and you can reactivate it later if a dormant customer returns.
Why does this matter? Inactive lists can slow down name lookup and make reports longer to scroll through. For businesses with thousands of old customers, a conversion is a good moment to separate what you truly need from what is only history. We can include every inactive name, exclude the ones with no transactions, or move only the last few years of names if the file allows it. What is possible depends on the Sage 50 file itself, so we check the file before we set the scope.
If you want to trim the list
Tell us before the conversion starts whether you want every inactive name included. When the file is large, our engineers can produce a list of inactive customers and vendors with their transaction counts so you can decide in concrete terms. We have done this for companies moving from Sage 50 to QuickBooks, and it is a normal step in our conversion workflow.
If you are unsure what your file contains, send us a copy of your Sage 50 backup and we will list every inactive customer and vendor before anything is built.
