Will my open customer invoices and unpaid vendor bills convert from Sage 50 to QuickBooks?

Yes. Open customer invoices and unpaid vendor bills convert as open QuickBooks invoices and bills, with due dates and aging carried across.


Yes, they do. In a Sage 50 to QuickBooks conversion, open customer invoices come across as open invoices in Accounts Receivable. Unpaid vendor bills come across as unpaid bills in Accounts Payable. Each document arrives still owing, so your receivable and payable totals carry over as live, collectible amounts rather than a single summary entry.

How do due dates and aging carry across?

Due dates travel with each invoice and bill. Aging in QuickBooks is computed from those due dates, so the buckets on an aging report in QuickBooks line up with the aging you last printed from Sage. The open balance per customer and per vendor carries as well, which is what lets the two systems agree on who owes what.

What about partially paid invoices and credits?

An invoice that is partly paid converts with the payment applied, leaving only the remaining amount open. Credits have direct equivalents in QuickBooks, and the aim is to keep them attached to the right names so net balances match. Exactly how these land depends on how payments and credits were recorded in your Sage file, so we confirm that during the evaluation rather than assume it.

The details that depend on your file

Not every Sage file converts identically. Very old open items, heavy job tracking, unusual account mappings, or a file with damage can change what comes across cleanly and how much cleanup follows. Our engineers look at the file first, then tell you what to expect before anything runs. If you are planning the move, see our Sage 50 to QuickBooks conversion service.

A check worth running after the move

Print or export the A/R and A/P aging summaries from Sage as of the conversion date. Then run the same reports in QuickBooks and compare totals, plus the balance for each customer and vendor. They should agree. When a line differs, it is usually one document that did not land as open, and it is far easier to fix while the Sage reports are still in hand.

The useful next step is a free evaluation. Send us a backup of the Sage file and we will report exactly which open invoices and bills will convert. We will also flag anything that needs a decision and quote the job before work begins.
