Purchase orders raised against the job they belong to
Materials bought without a PO are materials nobody costed. Gaffer raises a numbered purchase order against a job and a supplier, emails it, and tracks it from sent to received — so what you committed to spend is attached to the work it was spent on.
Replaces a separate invoicing app and a folder of unpaid PDFs. Money arrives in days rather than weeks, and nobody has to make the awkward phone call.

Invoice from the driveway. Get paid before you leave it.
One tap turns the job into a branded invoice with a Pay Now link — card, Apple Pay, Google Pay or Direct Debit. Reminders chase politely on your behalf. Xero or QuickBooks are updated for you.
Debtor days drop from weeks to days, and nobody has to make the awkward phone call.
- Supplier name and email, with orders sent by email from Gaffer
- Linked to the job the materials are for
- Line items with a calculated total
- Status tracked with sent and received timestamps
- Notes carried on the order for delivery instructions
- Feeds job costing so committed spend shows against the job
Step 05 of the job: invoice
Marking the job complete raises the invoice from the accepted quote, nets off the deposit, attaches the certificate and sends it with a Pay Now link — before the van has left the drive.
Purchase orders is one part of that step. The rest of the job — quoting, scheduling, certificates, invoicing and payment — runs in the same system, on the same record. See the whole job →
