What we do
CheckMySupply is an invoice watchdog for plumbing, HVAC, and electrical shops. We read every supplier invoice — catching price creep, billing errors, and duplicates before you pay — and draft the polite credit request for every finding. Prices drift, systems slip, we catch it, you collect.
- Unit prices compared against what you paid in March — on every SKU, every invoice
- Quotes checked against the counter ticket and the final invoice
- Quantities checked against packing slips
- Duplicate invoices caught before they're paid twice
Start with the free first look
Forward the invoice email, or snap a photo — crumpled is fine. That's the whole job. You get back a report of what drifted, what slipped, and what to ask credit for, receipts attached. Free, either way.

Pricing is on the site — about half an hour of billable time a month. No contracts, and if you cancel, you keep your price history.
