Most business owners feel it for years before they have documentation. We built a forensic system that finds the overcharges, builds the proof package, and makes your supplier unable to argue with the numbers.
GraphLedger translates any document corpus into a live knowledge graph — then runs deterministic Python models across every node and edge simultaneously. Most clients start with supplier accountability. Where you go next is up to you.
They knew something was off. The invoice volume was too high, the job pace too fast to check line by line. That is exactly the condition this pattern requires to survive.
Here is what we found and why it matters. When we compared invoices to quotes, the same thing kept appearing. The item on the invoice looked almost identical to the item on the quote — same product, same manufacturer, same description. But the SKU was slightly different, and the price was dramatically higher.
Schedule 40 PVC quoted. Schedule 80 PVC invoiced. Description similarity: 99%. A human reviewer sees the same product. Our system saw a different SKU, a different grade, and a price multiplier that in one documented case reached 29.23× the quoted price — $0.87 quoted, $25.31 billed, on a commodity fitting ordered ten at a time.
What made this finding decisive was consistency. The same substitution logic appeared across 8 of 14 job sites. A fulfillment error appears once. A pattern that replicates across 153 instances is either a system or a policy. That distinction matters enormously in what comes next.
46 units. $518.10 uplift on a single line item. Description similarity: 99%. Nobody checked — each one was just a few dollars.
Three characters different in the description. 29-fold price multiplier on 10 units. Similarity: 94%.
Both grade and size stepped up simultaneously. $266.83 uplift on 10 units. Repeated across multiple job sites.
Every finding is documented with the source quote, the source invoice, the exact discrepancy, and the dollar amount. Everything the client needs to present to their supplier without dispute. The supplier knows the numbers are wrong. The client just never had the proof before.
Client identity protected under NDA. Supplier identity withheld pending engagement resolution. The forensic record has been delivered. What happens next belongs to the client.
Three steps. No technical knowledge required. You run your business — we watch your documents.
Send us 30–60 days of supplier invoices and the quotes you received. We set up a private encrypted document channel on first contact. That is all we need to begin.
Every document translated to linked data. Every node cross-referenced — prices, quantities, SKUs, patterns across time. The full history held simultaneously. No human review matches this depth or speed.
A findings report with complete documentation. Every discrepancy sourced and provable. Your supplier cannot argue with the numbers. Credits applied to your account.
Most overcharges are quiet patterns compounding invisibly over months and years — impossible to catch without the right instrument.
Invoiced price above what was quoted. Small per unit — massive in aggregate over 12 months.
99% description similarity, completely different SKU, 6× to 29× the quoted price. The exact pattern documented above.
Billed for 120 units when you ordered 100. Manual verification cannot catch this across thousands of line items.
Same item charged twice across different invoices. Hidden in volume, compounding silently every billing cycle.
Small incremental increases compounding over months. Your gut has felt it for years. The system finds and documents it.
Items delivered with no agreed price — supplier sets it unilaterally. 74.9% of one contractor’s spend had no quoted reference.
Select your situation and see the real numbers side by side.
GraphLedger translates every document into linked data and runs deterministic Python models across every node and edge simultaneously. What takes an accountant days takes the system minutes.
What manual review misses across six months of invoices — like 153 instances of SKU substitution across 8 job sites — the system flags in a single pass. Not because the accountant isn't skilled. Because the volume and complexity is not humanly manageable at the precision required.
Every finding traces to a source document, a line item, and a timestamp. The supplier cannot argue with provenance.
No packages. No tiers. Your situation is yours — and the first conversation is always free.
We talk. You tell us what you're feeling in the numbers, which supplier relationships feel off, how long it's been going on. No forms. No obligation.
We map your situation together — suppliers, quotes, invoice history, what you have and what you don't. We tell you exactly what each scenario makes possible.
Exactly what we can find, what we need, and what a realistic outcome looks like. If this isn't the right fit, we'll tell you that too.
We scope it, open your secure document channel, and begin. First findings in 3–5 business days. Every discrepancy sourced, documented, and ready to present.
Most clients have felt something was off for months — sometimes years — before they had the documentation to act on it. That gap between the feeling and the proof is exactly what we close. Tell us what's happening and we'll tell you honestly what we can do about it.
The free audit costs you nothing. If we find overcharges you decide what to do. If we find nothing — you sleep better knowing your suppliers are clean.
