Find the money hiding in your business.
Right now, a supplier is probably overcharging you — a price that crept up, an invoice paid twice, a rate off contract. You don't have time to catch it. That's what we're built for.
How a hidden price rise shows up.
You earned it. You just gave it away.
This is the kind of money that hides in overpayments and billing errors across supplier spend. It's an estimate until we see your data — but it's rarely zero.
The stuff your invoices won't tell you.
Every bill and contract, checked against what you actually agreed to pay. Here's the kind of thing that turns up.
Nobody has time to read every line.
Overpayments don't hide in one big red flag — they hide in the hundredth receipt in the pile, the invoice nobody double-checked. CostWarden reads every single one, so your team doesn't have to.
How much could you get back?
Move the slider to your annual supplier spend for an estimate of your addressable savings — the money most likely hiding in overpayments and leakage.
Based on spend patterns typically associated with cost leakage. Your actual opportunity depends on your data — the free Cost Control Assessment gives you the real number.
