Start with the free check: have you paid any supplier twice?
Drop in an export of your supplier invoices or bills (CSV or Excel, from Xero, QuickBooks, Sage or a spreadsheet). The check runs entirely in your browser: your file never leaves your computer. You see the result in seconds, compared with published benchmarks.
The free check looks for possible duplicate payments. The full review also checks prices against orders and contracts, quantities against deliveries, missed price rises, expired discounts and unbilled work.
To build fair benchmarks, the check keeps only anonymous totals (number of lines, share of possible duplicates, sector). Never names, invoice details or amounts. See our privacy notice.

Money slips out at four points between doing the work and banking the cash
Tap each leak to see what it usually looks like. Most businesses have at least one and don't know it, because nobody's job is to look.

- Unpaid findings and your records are deleted after 30 days.
Supplier savings: our fee is based on the savings we find
We find where your business is paying more than it needs to and show you exactly how to save. If you want, we then put the savings in place for you.
We assess your costs from your records and documents, then send you a written proposal with our initial findings and the full terms.
You see the proven total and one saving in full first. The detailed report shows every saving, the evidence and how to achieve it.
Optional. Our procurement specialists negotiate with your suppliers, and every offer comes back to you to accept or decline.
- “Proven” means backed by written quotes, your own records or published benchmarks. Estimates are shown but never charged for.
- We take on work where we expect at least £2,000 a year in savings. Energy contracts are signed directly between you and the supplier, and insurance work is limited to reviewing your cover.
- Ask for it from your report after a full review, or email hello@sidraadvisory.com. Full terms are in clause 14 of our terms.

The experience behind every Sidra Advisory review
Over 10 years of recovering revenue, checking supplier spend and tightening contracts for public bodies, healthcare providers and major projects sit behind every review. Choose a result to see how it was done, or read every case study.
See what a review could be worth to you
Enter your revenue and your own guess at the leak. The chart shows what a three-year review could find and how it would split. If we confirm nothing, you pay nothing. Older items can fall outside the time limit for claims, so the sooner you look, the more you can usually claim.
Example figures using the 25% standard fee (20% if you unlock within 7 days). This calculates your own assumption; it is not an estimate. A review is how you find the real figure.
Who owes the money decides what you get
| Who owes it | Typical examples | What your report gives you |
|---|---|---|
| Your suppliers | Duplicate payments, charges above the agreed rate, credit notes never received | The evidence for each item and a draft claim letter for each supplier, ready for you to send |
| Your customers | Extra work never invoiced, price rises not applied, discounts that should have ended | The amounts to invoice and a covering note for each customer. You send them, so the relationship stays yours |
Before you start
What happens if you find nothing?
You pay nothing. The free check and the full review cost nothing. You only pay if we confirm findings and you choose to unlock them.
Why do I pay before I see the details?
Because the details are the product. Before you pay you see the confirmed total, the breakdown by type and supplier initials, and one finding in full with its evidence, so you know the rest is real. If a supplier shows a finding was wrong, we refund the fee for that finding.
How is my data handled?
The free check runs in your browser and your file is not uploaded. For the full review, files are used only for your review under a data processing agreement and deleted on a fixed schedule. Only anonymous totals, such as the share of payments that were duplicates, are kept to build benchmarks. See the privacy notice.
Can you help us pay suppliers less from now on?
Yes. Every full review includes a free spend analysis: the same item bought at different prices, price rises from the same supplier, and where your spend is concentrated, all worked out from your own invoices. If you want to go further, we assess your costs and prepare a savings report showing every proven saving, the evidence and how to achieve it. Our fee for the report is 20% of the proven annual savings. If you would like us to put the savings in place, our procurement specialists negotiate with your suppliers for a fixed fee, and every offer comes back to you to decide.
Will you contact my suppliers or customers?
Not about the findings: those are yours to act on, with the evidence and draft letters in your report. We contact suppliers only if you ask us to negotiate prices for you, and only with your written authority.
Is this advice?
No. It is analysis of the records you give us. We are not your lawyers or accountants, and you should check each finding against your own records before acting. See our terms, which limit our liability.
How far back do you look?
As far back as the records you send, usually up to six years. Each finding shows the date after which a claim may be out of time, so you can act on the oldest first.
How long does it take?
The free check takes seconds. Confirmed findings from the full review usually follow within three working days of your upload.
