Pre-launch · free for UK builders
Upload one invoice. We’ll check every line.
A recent invoice, quote, or matching pair — PDF or photo. We check what moved, what looks fair, and what’s worth asking your rep about. No login, no supplier contact.
Upload one document
A recent invoice, quote, monthly statement, or quote-and-invoice pair from any builders' merchant.
We check it ourselves
Quote-vs-invoice mismatches, price jumps, branch differences, list-price charges — checked by one of us, not a bot.
You get the wording
A short readout plus a relationship-safe note you can send to your rep yourself. We never contact your supplier.

How we check the first invoice.
The free check is a human review of one supplier document or one quote-and-invoice pair. We look for line-level differences and relationship-safe questions; we do not contact the supplier, negotiate on your behalf, or give tax, accounting or legal advice.
Uploaded files are handled under the privacy policy. Ask us to export or delete the file by email.
What comes back
A useful first reply, not another login.
Line by line, in plain English, with the numbers that matter. Like this:
- PIR board 100mm ×14£38.90 → £44.20
- C24 timber 47×100£4.12/m → matched
- Plasterboard 12.5 ×30£9.80 → £11.45
After the first one, ask us for the WhatsApp number.
Builders who want the easier ongoing flow forward invoices by WhatsApp during the pilot. Email works fine for the first check.
