Procore × Xero integration.

A custom-built sync between Procore and Xero. Project budgets, commitments, invoices, contacts, and payments move bidirectionallybetween Procore’s REST API and Xero’s Accounting and Projects APIs — covering the gaps Procore’s native connector leaves open. Multi-currency aware, retainage handled, code lives in your repo.

01. What syncs, what doesn’t

Specific objects. Specific directions.

Generic “syncs financial data” language is how integrations end up broken. Below is the actual object map for a typical Procore × Xero build. Direction is configurable per object during the audit. Anything not listed stays manual on purpose.

What stays manual: chart-of-accounts changes, year-end adjustments, opening-balance entries, and journal entries originated in Xero. The integration writes transactions and reads state. Structural Xero changes flow through the controller, not the sync.

Already on Procore’s native Xero connector and hitting its limits?

The 14-day audit maps exactly which objects the stock connector covers and which it can’t — budgets, prime contracts, project-specific cost codes — and produces a written plan for the custom layer that fills the gaps.

02. The boundary problem this solves

Xero wasn’t built for construction WIP.

Construction firms that grew up on Xero end up double-keying project commitments because Xero’s Projects module wasn’t built for construction-grade WIP accounting. There’s no native concept of cost-to-complete, no retainage primitive, no commitment vs. actuals tracking against a Schedule of Values. So the project manager works in Procore and the controller works in Xero, and the two reconcile in a spreadsheet on Friday.

The integration closes that gap without forcing either side to learn the other’s mental model. The project manager keeps working in Procore. Budget changes, commitments, change orders, billings. The controller keeps working in Xero. Bank rec, AR aging, AP runs, multi-currency revaluations. The connector handles the translation in both directions, and the two systems show numbers that reconcile without a Friday spreadsheet.

This is the integration we get asked about most often by mid-market GCs and specialty contractors that already run on Xero and don’t want to migrate to a heavier ERP just to plug into Procore.

The Procore × Xero integration isn’t about replacing the controller’s tooling. It’s about making sure the controller and the project manager see the same project without anyone re-keying numbers.

03. How we build it

Public APIs on both ends. No middleware platform.

The Procore side runs on the Procore REST API v1.0 with OAuth 2.0 for the company-scoped token and webhook subscriptions for change events on budgets, commitments, invoices, and contacts. The Xero side runs on the Xero Accounting API and, where relevant, the Xero Projects API, also via OAuth 2.0 with tenant-scoped tokens and the Xero webhooks for contact and invoice changes.

The transformation layer is a small Node service that holds the field-mapping config, the direction rules, and the reconciliation jobs that catch what webhooks miss. Scheduled jobs sweep budgets nightly and reconcile payment status hourly. Errors land in a queue with a manual-approval UI for the controller; we don’t silently overwrite Xero records when something looks off. Code lives in your repo, infrastructure in your cloud, OAuth tokens in your secret store. If you ever switch vendors, the integration goes with you.

04. Where this fits in our engagement model

Three modes. Pick where you are.

— DIAGNOSE

The 14-Day Audit

Fixed fee · 14 days

We map the Procore × Xero surface end-to-end. Which objects sync, in what direction, what stays manual. Output: a written 90-day plan with the data flow diagram, the field mapping, and a real estimate. More on the audit →

— BUILD

The Build Engagement

Scoped quote · 8–12 weeks

The implementation. OAuth flows, the transformation layer, the reconciliation jobs, the controller-facing exception UI. Tested against your actual Procore project data and your Xero tenant. Shipped to production with monitoring.

— EMBED

The Retainer

Capped hours · Monthly

Both Procore and Xero ship API changes. We retain a fractional engineering presence to handle version updates, new object mappings, and the controller’s next request. Capped hours, monthly billing.

Want to see the sync running against your actual chart of accounts?

15 minutes with a Procore developer — we’ll walk the object map against your Xero tenant and your Procore project structure, and tell you straight whether the native connector covers you or you need the custom layer.

05. Frequently asked

Procurement-stage questions we get on this one.

Doesn't Procore already have a built-in Xero connector?

It does. Procore's ERP Integrations program includes a first-party Xero connector that exports cost codes, projects, vendors, commitments, purchase orders, commitment change orders, and subcontractor invoices to Xero, and imports job costs and bill payments back. For a straightforward operation, start there — it's included. Our work is what the stock connector explicitly can't do: it doesn't sync budgets, prime contracts or prime-contract invoicing, project-specific cost codes (it uses one company-wide list), custom WBS segments, or sub jobs, and it caps you at one Xero organization per Procore company. If you run multiple entities, bill from prime contracts, or have a cost-code structure the connector can't represent, that's the custom build — and we design it to run alongside the native connector, not rip it out.

Can we sync project budgets bidirectionally?

Yes. Procore's budget line items map to Xero tracking categories or to Xero Projects depending on how your accountants run WIP. Bidirectional sync is possible but rarely correct — most operators want budget as a read from Procore and actuals as a read from Xero, with a reconciliation report that highlights drift. We design the direction during the audit so you don't end up with a feedback loop between two systems updating each other.

What about multi-currency projects?

Xero handles multi-currency natively on its Premium plan. The integration carries currency context on every line and uses Xero's rate at the document date for postings into Procore. For Procore-side budgets in a non-base currency, we hold the conversion at the project header so reporting stays consistent across the controller's view and the project manager's view.

How do retainages flow between Procore and Xero?

Retainage isn't a first-class concept in Xero the way it is in Procore. We model it as a retainage liability account in Xero plus a tracked category for the held-back amount, and the integration writes the retention release as a separate invoice transaction at the milestone Procore marks it released. Construction firms running on Xero usually want this; firms doing light commercial often don't bother and we leave it manual.

Will this work with the Xero Projects module or only the Accounting module?

Both. The Accounting module is mandatory for the invoice and contact sync. Xero Projects is optional. If you're already running Xero Projects for time and expense capture, we map Procore project IDs to Xero project IDs and keep the labor cost flow bidirectional. If you're not on Xero Projects, all project context lives in Procore and Xero sees only the financial transactions.
