dueproof

Find what your client agreements say you can bill — and aren't.

For US managed IT providers. We compare three of your client agreements with three months of your invoices and seat counts, and name every term you are not billing.

What the check finds

Every finding names the contract clause and the invoice behind it, and is classed as recoverable now, fixable going forward, or needs evidence first. The classes are never added into one headline number.

How it works

  1. You email three client agreements, three months of invoices, and your seat or device counts.
  2. We build a term sheet from your agreements — every price, minimum, increase and billing clause, with its clause number — and you approve it.
  3. You get a written report within five business days.

Price and refunds

$500 for one check: three agreements, three months.

You pay by link once we confirm your files are complete.

What we don't promise

That any money will be recovered, or that you are legally entitled to bill any amount. The report compares your documents with your invoices; it is not legal or accounting advice. Check any finding against the cited clause before you bill a client. Everything is by email — no calls or meetings.
