The Client's Problem

A mid-sized Brisbane residential builder was losing money between site and office. Supervisors captured photos, dockets, and variations in the field, but admin manually re-entered everything into Xero and project management software — delaying invoicing, hiding budget blind spots, and compounding costly errors across every job.

The OceanSoft Solution

Built a custom API integration with Microsoft Power Automate and Python to bridge field software directly to Xero. Site approvals now automatically generate draft invoices and update project budgets in real time — no manual re-entry, no chasing paperwork.

The Measurable Outcome

Eliminated all double-handling of financial data and cut the client invoicing cycle by four days. Delivered as a one-off bespoke integration with no ongoing subscription fees, no retainer, and full ownership from day one.

The Site-to-Office Gap

Field supervisors were doing the right work on site — photos, dockets, variation approvals — but finance only saw it after admin re-keyed data into Xero and their project system. Variations sat in inboxes, budgets drifted unnoticed, and invoice runs slipped by days on every project.

Integration Flow

We connected the field platform to Xero with a Power Automate orchestration layer and Python micro-services for validation and mapping logic:

  1. Approved site dockets and variations trigger a webhook from field software
  2. Python normalises line items, cost codes, and GST treatment against business rules
  3. Power Automate creates draft Xero invoices and posts budget actuals to the project ledger
  4. Exceptions (missing PO, rate mismatch) route to a single admin queue — not full re-entry

Supervisors keep their existing mobile workflow; finance gets structured data the moment work is approved on site.

Real-Time Budget Visibility

Project managers see committed and actual costs update when variations are signed off — not at month-end reconciliation. That closed the blind spot that had been letting margin erosion go unnoticed until jobs were nearly complete.

Engagement Model

One architectural delivery: integration design, deployment, runbook, and handover. No retainer, no per-transaction SaaS middleware fees — the builder owns the integration and the Microsoft/Xero accounts it runs on.
