If you run a contracting business, your accounting software is not just where the taxes get done. It’s where job costing lives, where you find out whether last month’s kitchen remodel actually made money, and where payroll either runs clean or eats your Friday afternoon. QuickBooks and Xero are the two names that come up most for shops your size, and they take genuinely different approaches to the same job. Here’s an honest head-to-head. Whichever you pick, one number feeds both systems: your real labor cost. Our free true labor cost calculator adds the burden — taxes, insurance, and comp — to the wage, so job costing starts from the truth.
What Each One Is
QuickBooks Online
QuickBooks Online is the default small-business accounting platform in the US, and that default status matters. Most bookkeepers and CPAs your shop might hire already know it. It handles invoicing, expense tracking, bank feeds, sales tax, and payroll through its own add-on payroll service. The contractor-specific value is in its project and job costing features on the higher tiers: you can tag income and expenses to a project, track labor and material costs against it, and see profitability by job instead of just by month.
Xero
Xero came up through Australia and New Zealand and built its reputation on a cleaner interface and strong bank reconciliation. It does the core accounting job — invoicing, bills, bank feeds, expense claims — and handles multi-currency better than most. Its project tracking exists but is lighter: Xero Projects lets you track time and costs against a job, but it’s a simpler tool than what QuickBooks offers on its top tiers. Xero does not run its own US payroll; it relies on integrations with third-party payroll providers.
Job Costing: Where Contractors Should Decide
This is the category that matters most for a contractor, and it’s where the two separate.
QuickBooks Online’s project costing lets you pull labor (through its time tracking and payroll), materials, subcontractor bills, and overhead allocations into one job view. If your bookkeeper keeps it current, you can answer the only question that counts: did this job make money, and where did it leak? The catch is tier — the real project profitability tools sit on the higher-priced plans, so check current pricing and which tier includes projects before you commit.
Xero’s job costing is serviceable for simple tracking — assign costs to a project, see a basic summary — but it wasn’t built around construction-style job costing. Shops that need work-in-progress (WIP) reporting, retainage tracking, or percentage-of-completion views will end up bolting on a construction-specific app either way. To be clear: neither QuickBooks nor Xero does true construction WIP the way a dedicated construction accounting system does. If your bonding or bank requires formal WIP schedules, your CPA is building that in spreadsheets regardless of which of these two you pick.
Payroll and Integrations
Payroll
QuickBooks offers its own payroll product that runs inside the same system — hours flow into job costs without an export-import dance, and tax filings are handled in-house. For a contractor paying field crews, that tight link between payroll and job costing is a real operational advantage.
Xero routes US payroll through integration partners. That works fine, and some of those partners are excellent, but it’s one more login, one more bill, and one more place for a sync to break. If your payroll includes certified payroll reporting for prevailing-wage work, you’ll be evaluating the partner apps carefully on either platform — neither core product makes that paperwork disappear.
Integrations
Both connect to the apps contractors actually use — estimating tools, field documentation, payment processors, and your CRM. QuickBooks has the edge in the US contractor ecosystem simply because it’s the bigger target: most construction apps build their QuickBooks integration first. Xero’s app marketplace is large and well organized, but check your specific stack — your estimating or project management tool may sync more completely with one than the other. Do this check before you choose, not after.
Day-to-Day Use
Xero’s interface is the cleaner of the two. Bank reconciliation is fast, the dashboard answers “who owes me and who do I owe” at a glance, and non-accountants tend to dislike it less. QuickBooks Online has improved over the years but still buries common tasks under menus, and its layout changes often enough to annoy long-time users.
Support and the local ecosystem tilt the other way. Finding a bookkeeper who knows QuickBooks takes one phone call in most US markets. Finding one who’s deep on Xero is getting easier but is still a smaller pool, and Xero’s US presence — particularly around sales tax and state-specific quirks — has historically been thinner than its international game.
On pricing: both use tiered monthly subscriptions that change regularly, and both gate the features contractors need most (projects, job costing) behind higher tiers. Don’t budget off a blog post — check current pricing on both sites and price the tier that actually includes job costing, plus payroll, before comparing totals.
The Pick
For most US contractors, QuickBooks Online is the pick. Not because it’s better software in the abstract — on pure interface, Xero wins — but because of the three things that decide accounting software in practice: job costing depth on the higher tiers, native payroll that feeds those job costs, and the fact that every bookkeeper, CPA, and lender in your world already works in it. When your accountant asks for access at tax time, there is no conversion conversation. That ecosystem gravity is worth real money.
Pick Xero instead if: your jobs are simple enough that basic project tracking covers your costing needs, your bookkeeper already runs Xero, or you do meaningful work billed in other currencies. If your office manager hates QuickBooks so much that the books stay two months behind, a cleaner tool that actually gets used beats a deeper tool that doesn’t — an accounting system nobody updates is worse than a simpler one that’s current.
Skip both if: you’ve outgrown small-business accounting — multiple entities, heavy WIP and retainage reporting, bonding requirements. That’s construction-specific accounting territory, and forcing QuickBooks or Xero into that role costs more in workarounds than the dedicated tools cost in subscriptions.
The Bottom Line
Choose based on job costing and who has to live in the system. QuickBooks Online for most US contracting shops; Xero for simpler operations with a Xero-fluent bookkeeper. Either way, the software is the smaller half of the job — the bigger half is the discipline of coding every cost to a job, every week, so the numbers mean something when you read them.
Not Sure Your Systems Are Set Up Right?
Accounting is one piece of the puzzle. If your estimating, follow-up, and job tracking don’t talk to each other, the numbers never add up no matter which platform you pick. We help contractors sort out the whole stack — what to buy, in what order, and how to get it working together.
