How to connect QuickBooks to construction project data

Connecting QuickBooks to project data means every invoice, bill, and timesheet carries a job and a cost code, one system owns each record, and a monthly check proves the project side and the books agree.

To connect QuickBooks to construction project data, first set up each job as a project (or customer and sub-customer) in QuickBooks and agree on one cost code list used by both QuickBooks and your project software. Then decide which system is the source of truth for each record (customers, vendors, invoices, bills, payments, time), connect the two through a direct integration, and make sure every bill, invoice, and timesheet is tagged to a job and cost code. Finish with a monthly reconciliation so job cost in the project system matches job cost in the books. Without that last step, you have two sets of numbers that slowly drift apart.

QuickBooks is good at accounting. It is not built to run a construction project: change orders, schedule of values, retainage by line, committed costs, RFIs, and daily logs. That is why most contractors on QuickBooks pair it with project software. The connection between the two is where job costing succeeds or fails.

What QuickBooks Online can track by job

Intuit's help documentation says QuickBooks Online Plus and Advanced include Projects, which track income and costs for specific projects. You assign estimates and invoices to a project in the Customer field, and bills, checks, and expenses in the Customer/Project field, with a billable checkbox for costs you want on a future invoice. For Advanced users, Intuit says you can track estimate versus actuals on the project dashboard and reports. Intuit's pricing page, checked in October 2026, listed project profitability tracking on Plus and Advanced, and a construction financials feature on Advanced. Features and plan names change, so confirm on Intuit's site for your subscription.

What QuickBooks does not do on its own is the construction workflow: committed costs from subcontracts and purchase orders, pay apps with retainage, change order approval, and cost-to-complete. Those live in project software and need to feed the books cleanly.

How to connect QuickBooks to project data in 7 steps

  1. Set up jobs the same way in both systems. One project per contract in QuickBooks, with the same job number and name in your project software. Decide how you handle change orders (same project) and service work (separate customer or project).
  2. Build one cost code list. Use a short list that matches how you estimate. Map it to QuickBooks items or classes consistently. See how to build a construction cost code structure.
  3. Pick a source of truth for each record. A common split: project software owns budgets, commitments, change orders, and pay apps; QuickBooks owns the chart of accounts, payments, payroll, and bank activity. Write it down.
  4. Connect through an integration, not exports. A direct connection syncs customers, vendors, invoices, and bills without retyping. Test it on a sandbox or a copy of your company file first.
  5. Tag every transaction to a job and cost code. Sub invoices, supplier bills, credit card charges, and timesheets. Untagged costs are invisible to job cost.
  6. Handle labor carefully. Time entered in the field by cost code should flow to payroll and job cost with burden. See how to calculate labor burden.
  7. Reconcile monthly. Compare job cost by job in the project system to QuickBooks. Investigate any job that differs. See how to reconcile job costs with QuickBooks.

Worked example: a drywall sub getting job costing right

Say a drywall and framing sub doing $3.5 million a year runs QuickBooks Online Plus. Bills are entered by the bookkeeper, and about a third of material bills are not assigned to a project. The owner's job profit report shows one $410,000 job at a 31 percent margin, which seems too good.

They connect project software to QuickBooks. Jobs are created in the project system and synced to QuickBooks as projects. Supplier bills are uploaded, approved by the PM, coded to job and cost code, and synced. Field time comes in by cost code. At the first monthly reconciliation, they find $46,000 of board and metal stud bills for that job sitting in general expense. Once corrected, the job's margin is about 20 percent. Lower, but real, and now the PM knows the remaining budget for material is tighter than he thought. These figures are illustrative, but uncoded material is a common reason a job report looks better than reality.

Desktop vs. online

The steps above assume QuickBooks Online, because cloud integrations are simpler to connect and keep in sync. If you run a desktop version of QuickBooks, ask each project software vendor exactly how their connection works: whether it needs a connector installed on the computer that hosts the company file, how often it syncs, and what happens when that computer is off. Some contractors use a software change as the moment to move their books online, which is a decision to make with your accountant.

Mistakes to avoid

  • Different job names in each system. "Smith Medical" and "Smith Med Office Bldg" become two jobs in a sync. Use job numbers.
  • Too many cost codes. A 200-line list means nobody codes correctly. Start smaller.
  • Two-way editing of the same record. If both systems can edit an invoice, they will eventually disagree. One owner per record.
  • Ignoring committed costs. QuickBooks shows costs when bills arrive. Without committed costs from subcontracts and POs, job cost lags reality. See how to track committed costs.
  • Skipping the monthly reconciliation. Sync errors are small when caught monthly and painful at year end.

Tools and next steps

If you are evaluating whether QuickBooks is still the right fit, see QuickBooks for contractors alternatives. For the bigger picture, read how to set up job costing for a construction company. Smart Business Automator connects to the accounting tools contractors already use and keeps budgets, commitments, change orders, invoicing, and job costing and WIP views on the project side.

Frequently asked questions

Can QuickBooks do job costing for construction?

QuickBooks Online Plus and Advanced include Projects, which track income and costs by project, and Intuit says Advanced adds estimate versus actuals. Construction-specific items such as committed costs, retainage by line, and change order workflow usually need project software connected to QuickBooks.

Which QuickBooks Online plans include projects?

Intuit's help documentation lists Projects for QuickBooks Online Plus and Advanced. Check Intuit's current plan pages, since features and plan names change.

Should project software or QuickBooks be the source of truth?

Split it by record. Project software usually owns budgets, commitments, change orders, and pay apps. QuickBooks usually owns the chart of accounts, payments, payroll, and bank activity.

Why doesn't my job cost in QuickBooks match my project software?

Common causes are bills not assigned to a project, mismatched cost codes, timing differences between committed and invoiced costs, and records edited in both systems. A monthly reconciliation by job finds them.

Is exporting CSV files between systems good enough?

It works for very small volumes but invites retyping errors and missed records. A direct integration that syncs on a schedule is more reliable once you have several active jobs.
