How do I handle Sage 50 retainage and progress billing data in QuickBooks?
QuickBooks has no native retainage feature, so Sage 50 retainage typically converts to invoices plus journal entries or a clearing-account workaround.
QuickBooks Desktop and QuickBooks Online do not have a built-in retainage function the way Sage 50 handles it, so retainage and progress billing data cannot be converted as a native “retainage receivable” line. It depends on your file, but in practice the data maps to standard invoices with the held-back portion tracked through a clearing account or journal entries, and our engineers set this up as part of the conversion.
What happens to retainage during conversion
In Sage 50, retainage is usually stored as a withheld amount on each progress invoice, with the receivable split between what is billable now and what is held back until the contract completes. When that data moves to QuickBooks, there is no matching field, so the held-back amount has to be represented another way. The two common approaches are:
- A retainage receivable clearing account. Each progress invoice is entered in QuickBooks for the full contract value of the billing period, with the retainage portion posted to the clearing account instead of Accounts Receivable. When the retainage is released at the end of the job, an invoice pulls the amount back out of the clearing account.
- Journal entries. If historical retainage balances are all you need, a single journal entry per customer or per contract can establish the outstanding retainage as of your conversion date, and you bill releases from there.
Which approach fits best depends on how much open retainage exists in your Sage file and whether you need transaction-level history or just the balances.
Progress billing
Progress billing itself converts more cleanly. Each Sage progress invoice becomes a QuickBooks invoice, and if you use percentage-of-completion style billings, QuickBooks progress invoicing from estimates can reproduce the pattern going forward: an estimate holds the contract value, and each invoice draws a percentage of it. Historical invoices carry over as regular invoices; whether the underlying estimate linkage can be reconstructed depends on the file and is something we evaluate before converting.
What we recommend
For open contracts at conversion time, decide per contract whether to (a) bring the full history across and rebuild the retainage tracking, or (b) start the contract fresh in QuickBooks with an opening journal entry for the outstanding retainage. Option (b) is often cleaner for long-running jobs with many small billings.
If you have open retainage on active contracts, send us your Sage 50 file for a free evaluation. Our engineers will review how your retainage and progress billings are structured and tell you exactly what can be converted, what needs the clearing-account workaround, and what the conversion will involve, with a no-obligation quote before any work starts.
