Xero for NZ Construction Companies: Connecting the Field to Your Accounts
Most NZ construction firms run Xero. Very few connect it to what actually happens in the field — so the office re-keys timesheets into payroll, codes supplier invoices by hand, and finds out a job lost money three months after it finished. Here's what field-to-Xero integration should look like in 2026.
1. Timesheets → payroll without re-keying
The crew's approved hours — with rates and Holidays Act loadings applied — should flow to Xero as a ready-to-run pay item file. Fieldlink's Friday pay run does this in three clicks: pick the week, approve, export.
2. Supplier invoices coded to jobs automatically
The PlaceMakers slip your foreman grabs at the counter has a job number written on it. Fieldlink's AI scanner reads the photo, finds the job number, records the cost against the job and matches it when the monthly statement lands in Xero. No more shoebox of receipts.
3. Customer invoices tracked, not lost
Progress claims and cartage invoices raised from job data sync to Xero as draft invoices, then Fieldlink watches payment status — so overdue payments show up on your dashboard, not in a year-end surprise.
4. Real back-costing
- Labour: hours × cost rate from timesheets
- Plant: machine hours × internal charge rate
- Materials: scanned supplier invoices
- Result: live cost-vs-quote on every job, matching what Xero sees
What to check before connecting any tool to Xero
- Certified Xero API integration (OAuth, not password sharing)
- You control which invoices sync and when
- Mapping to your existing chart of accounts and tracking categories
- NZ GST handled correctly on every line
