Will customer deposits and vendor prepayments convert from Sage 50 to QuickBooks?

They usually arrive as credit memos or liability balances rather than active deposits, so each unapplied amount should be verified after conversion.


In most cases, yes, but not in the form you expect. The money converts and your customer and vendor balances arrive intact. What usually changes is the transaction type: QuickBooks does not reproduce a Sage 50 customer deposit or vendor prepayment as the same record. Depending on how each amount was booked in your Sage file, it typically lands as a credit memo, a vendor credit, or a balance in a liability account. The exact result depends on the file, so it is worth confirming before you commit.

Where do the balances land in QuickBooks?

A customer deposit in Sage 50 is money received before an invoice exists. Some companies hold those amounts in a customer deposits liability account; others post them straight against the customer. After conversion, the amount normally appears as a credit on the customer, ready to apply to a future invoice. Vendor prepayments mirror that: a vendor credit or a prepayment balance carried on the vendor. Either way, each customer’s and vendor’s running balance should match the Sage 50 figure on your conversion date.

How do you verify the unapplied amounts?

Print the aged receivables and aged payables reports from Sage 50 on the day before you switch, and note every name carrying an unapplied deposit or credit. Then, in QuickBooks, pull the customer balance and vendor balance reports and compare them line by line. The totals for those names should agree. Next, open the liability accounts and check that the amounts sitting there match your notes. A difference usually means a deposit was booked in a way the conversion mapped differently; it rarely means the money is missing.

Prepare the file before you convert

Apply whatever you can inside Sage 50 first. A deposit applied to an invoice before the move is one less unapplied balance to chase afterward. Keep a dated copy of the deposit and prepayment registers with your closing records. If a customer holds several deposits against open orders, note how you plan to apply them in QuickBooks, because the conversion cannot read your intent.

Our engineers review these balances as part of every Sage 50 to QuickBooks conversion, and we flag anything that will need manual attention once the file is open in QuickBooks.
