Six Sites. One Centralized Number. No More Phone Calls.

Project-Based Odoo ERP with Real-Time Procurement-to-Payment Visibility

"What does this site actually owe?" It used to take a morning of phone calls to find out. Now it's one screen, always current.

In construction, the same failure shows up on almost every multi-site operation: each site keeps its own numbers, and Head Office finds out what's owed only after someone goes looking for it. A short delivery gets lost in the shuffle. A subcontractor's claim turns into a week of back-and-forth over retention and past payments. Withholding tax gets calculated differently depending on who's doing the math that day.

For one multi-site contractor, that gap closed entirely — down to a single live number, read the same way from a site office or Head Office. Here's exactly how, and what it took to get there.

The Problem

Day to day, this is what the gap looked like

  • Every site kept its own records — one tool here, spreadsheets there, paper somewhere else — none of it talking to Head Office.
  • A short delivery could sit unresolved for days because nothing flagged it.
  • A subcontractor's claim meant re-arguing retention and past payments from scratch, every time.
  • Withholding tax landed differently depending on who processed it and when.
What Changed

What changed

We built one Odoo-based system, live for every site and Head Office at the same time. Every request — from a purchase at a site to a payment released at Head Office — moves through the same five-step chain and lands in the same books:

1
A short delivery opens a backorder automatically — it's tracked, not forgotten.
2
A subcontractor's claim is certified through an IPC that nets retention, backcharges, and past payments against the BOQ on its own.
3
Material handed to a subcontractor posts its own accounting entry the moment it happens — and reverses itself if it comes back.
4
Withholding tax calculates at exactly one point, when Finance releases payment.

The Outcome

The outcome

The same number — what a site owes, right now — reads the same whether it's pulled up on-site or at Head Office. Live in production today across three active sites, with the same system ready to switch on for the next one.

Running more than one site and still chasing this answer by phone?

Let's map where your sites and Head Office lose visibility — and what it takes to close the gap.
