A paper trail for every supplier invoice.
We check supplier invoices line by line — across suppliers, branches and sites — and write up what was overcharged, what was queried and what came back. You stay in control of the supplier relationship; we hand you the evidence.

What you get
Checks you can file, not just savings you can mention.
Every line, every branch
Quote vs invoice across your suppliers and their branches. Price jumps, list-price charges where a discount usually applies, and lines that drifted since the order — flagged with the numbers behind them.
A paper trail your QS will read
Each query is written up: what was charged, the range firms near the site pay, what we suggest asking, and what came back. An audit trail, not a spreadsheet of hunches.
A roll-up across sites
A monthly summary across sites and suppliers — where money leaked, what was recovered, which accounts are worth renegotiating. Reporting you can forward upwards as-is.
Worked example
One delivery, three lines queried, £412 documented.
The write-up names the lines, the quoted prices, the invoiced prices and the regional range — so the query stands up when the supplier pushes back, and so the file shows why it was raised.

How the site invoice file is written up.
The site-manager workflow is built around an audit trail a QS, contracts manager or director can read later. We separate the invoice evidence, the supplier question and the outcome, so the file shows why the query was raised instead of just showing a savings total.
The worked example on this page is illustrative. We need a consented firm example before using a named recovery, supplier response or measured savings claim as citation evidence.
How it starts
One site, one month, no rollout.
- 01
Send one month from one site
Invoices from a single site, however they arrive — PDFs, photos, a statement export. No system to roll out, nothing for the site team to learn.
- 02
We check and write it up
Every line against regional ranges and your own quotes. You get the queries drafted, with the evidence attached, ready for your letterhead.
- 03
You decide what goes out
Queries go to the supplier from you, not us — your account relationships stay yours. If the month is clean, we say so and you've lost nothing.
We’re three founders, pre-launch.
The first firms get us directly — a real conversation about your sites and suppliers, not a sales sequence. If what we do isn’t worth the money for your setup, we’ll tell you that too.
