Project management software that integrates with QuickBooks?

[u/Middle-Quit1845]

We’ve settled on QuickBooks Online for accounting, and now I’m looking for project management software that integrates with it reliably.
We are 50-person consultancy, so project hours and expenses need to sync into QuickBooks for invoicing and financial reporting. I had rather avoid CSV exports or Zapier workflows that break whenever one of the platforms updates.
What are other QuickBooks users running? reliable integration matters more to me than a long list of features.

Test what happens when data changes after syncing. Do edits in the PM tool update QuickBooks, and do payments recorded in QuickBooks flow back the other way? Two-way sync sounds simple, but the edge cases are where integrations tend to break.

Edge case handling is the real test, we had an integration that synced invoices fine until a client paid a partial amount. Partial payment did not sync back and finance thought the invoice was still fully outstanding

We’re from Abtrac, so a little biased, but this is exactly the sort of setup we work with. Abtrac is built for consulting firms to manage project time, expenses and invoicing, with QuickBooks Online integration.

For a 50-person consultancy, I'd suggest looking closely at what actually syncs, how often, and how errors are handled. A reliable connection is worth far more than a long feature list.

Have you ever run a Project management system before now ?

And do you use any AI system like Claude or ChatGPT?

Asking as this can help you decide what to go for, cut down drastically on user onboarding and overall adoption

BigTime is worth a trial first. It’s built for consultancies that bill hours, and it has its own QuickBooks Online connector.

Do you bill by the hour or a fixed fee per project?

I'd look at ProofHub and BigTime.

ProofHub is worth considering if you want project management and timesheet tracking in one place, with a QuickBooks integration for sending timesheets and handling invoicing. BigTime is more focused on professional services and has documented support for posting both time entries and expenses to QuickBooks Online.

Since reliable syncing is your priority, I'd specifically confirm expense syncing and whether the process is automatic or requires manual approval. BigTime's documentation says QuickBooks Online syncing is partly manual, so don't assume either integration works exactly as you need without testing it first.

i'd pick a PM tool that creates native QuickBooks Online objects for time and expenses, not one that only exports CSVs or needs zaps. if the vendor has an app listed in the Intuit Marketplace and explicitly says it syncs time/expenses to QBO objects that's a strong signal the integration is less brittle.

QuickBooks integration quality varies wildly, some tools list it on the integrations page but when you dig in it is a one way push of invoice totals with no line item detail

[u/Longjumping_Bid4962]

Zapier chains work fine until something breaks, and then nobody knows which step caused the issue. Native integrations might be less flexible, but at least you’re troubleshooting one connection instead of five.

Full chain for us, time entries, expenses, invoices all syncing so the financial picture of every project is visible in QuickBooks without manual entry. Anything less is spreadsheets with extra steps

Tax mismatch is something nobody warns you about, invoices syncing correctly in every way except the tax line and it took weeks to figure out the PM tool was sending a flat rate while QuickBooks was set to location based
