Fill in the delivery, drop in the mill certs, and download one signed PDF that goes out with the parts. No more copying last week's Word file and hunting for 3.1 certs.
Open last week's certificate, change the PO, miss the drawing revision. It happens to every shop.
Heat numbers on one sheet, certs in an email, a scan on someone's desktop. The pack takes longer than the paperwork should.
A missing cert or wrong heat number and the delivery sits in quarantine. Your invoice waits with it.
Customer, PO, part numbers, quantities, material and heat numbers. Saved parts and customers fill themselves in.
Drop in mill certs, test reports or a phone photo of a cert. PDF, JPG or PNG.
One signed PDF: your CofC first, every cert after it, each page numbered and stamped with the CofC number.

Type a part number and the description, drawing, revision and material fill in.
Pick the customer, the address is already there.
Draw it with a mouse or finger, or upload an image. It goes on every certificate you sign.
Find any certificate by PO, part or heat number when a customer comes back with a query.
The PDF is built on your computer. Mill certs and drawings are never uploaded.
Log in from the office, the shop floor PC or a tablet. Nothing to install, nothing to update.
