Both are mature cloud accounting packages and both handle purchase invoices perfectly well. Comparisons that declare a winner overall aren't much use, because the answer depends on where you are and what your paperwork looks like.
This is narrowed to purchase invoice processing — getting supplier bills in, coded, approved and paid.
Terminology, because it causes real confusion
In Xero, a supplier invoice is a bill. "Invoices" means sales invoices you issue.
In QuickBooks, a supplier invoice is also a bill, and suppliers are vendors in US versions and suppliers in UK ones.
Guidance about "importing invoices" very often means the sales kind. The field layouts are different, and this is the most common cause of a botched first import in either system.
Where they genuinely differ
Geography. Not a feature, and usually the deciding factor. Xero is dominant in the UK, New Zealand and Australia, with deep local tax handling and the accountant ecosystem to match. QuickBooks dominates the US. Whichever your accountant uses well is worth more than any feature on a comparison table.
Built-in capture. Both include it. Xero's is Hubdoc, bundled with most plans; QuickBooks has receipt capture in-app. Both are competent at header data — supplier, date, total — and both are shallow on line items. If you code a whole invoice to one account, that's fine. If you split across accounts, VAT rates or jobs, the work stays with you either way.
Approval workflows. QuickBooks has more built-in approval routing on higher tiers. Xero leans on the app ecosystem for anything beyond basic. If approval routing matters, check the tier you'd actually buy rather than the feature list.
The app ecosystem. Xero's is larger and more mature, particularly in the UK. This matters more than it sounds: most businesses end up wanting something the core product doesn't do, and the question becomes what's available and how well it connects.
Multi-currency. Both handle it; both restrict it to higher tiers. Check which tier if you buy from abroad.
Tracking dimensions. Xero allows two tracking categories. QuickBooks has classes and locations. Similar capability, different names, both adequate for most small businesses.
What isn't a real difference
Core bookkeeping. Both do double entry properly. Neither will let you down on the fundamentals.
Bank feeds. Both good, with the same occasional connection irritations.
Bulk import. Both take a file. Both are unforgiving about supplier names matching exactly, and both will happily create a new supplier from a trailing space.
Price. Close enough that it shouldn't decide it. Compare the tier you'd actually need, not the entry tier.
How to choose
Four questions, in order of how much they matter:
- What does your accountant use? If they're fluent in one, that's worth more than any feature difference. Ask before shortlisting.
- Where are you? UK, NZ or Australia leans Xero. US leans QuickBooks. Not absolute, but it decides the ecosystem and local tax depth.
- Do you need line-item detail? If you split invoices across accounts or jobs, neither built-in capture will get you there and you'll be adding something. Factor that into the real cost of both.
- What else needs to connect? Payroll, expenses, stock, e-commerce. Check your specific combination exists and is actively maintained — an integration with no updates in two years is a liability.
The honest summary
For purchase invoice processing specifically, they're closer than the marketing suggests. Both capture headers competently, both stop short of line-item depth, both rely on a third party for approval workflows of any sophistication.
If you already have one, the case for switching on invoice processing grounds alone is weak. Migration costs a period end and a reconciliation, and the gain is marginal. If you're choosing fresh, pick on geography and your accountant, then solve capture depth separately.
Cribble posts bills directly into Xero. For QuickBooks it exports CSV — a direct integration is planned but isn't live today, and it's worth knowing which you're getting from any capture tool, including this one. Either way it reads to the line item, which is the gap both built-in tools leave.
