Your paper job sheet, rebuilt for the phone.
Every trade has its own sheet: the checks you tick, the readings you record, the declarations the customer signs. 1 Sign doesn't make you fit someone else's form — you rebuild your own in the visual form builder, or clone one from the library and tailor it.
Drag-and-drop builder
Add sections, text fields, yes/no checks, dropdowns, grids and repeatable blocks — no code, no spreadsheet gymnastics. Upload a photo of your paper form as a guide while you build.
See how it worksStart from the library
General job sign-off, commercial door check sheet, window and composite door installation — clone a ready-made sheet and change what you need.
Capture signaturesCarries through to the certificate
Whatever your form captures appears on the branded PDF, laid out cleanly, with empty sections left off. Past sign-offs always keep the layout they were signed on.
Branded PDF certificatesBuild your own forms, done properly
Off-the-shelf job sheets never quite fit. The gas engineer needs appliance readings, the door company needs closer speeds and gap checks, the installer needs a per-window spec. With 1 Sign your engineers see the sheet your business actually uses — the same sections and wording they know from paper — just faster to fill in and impossible to lose.
Forms are built once from your control panel and are instantly available to every engineer. Repeatable sections handle multi-item jobs ("add another window"), and save-as-draft lets a sheet be finished over several visits before the customer signs. Form building is included on every paid plan; the free demo uses the ready-made library.
