Your scope, in
black and white.
Show exactly what you quoted, what you finished, and what was a variation - marked on the boat’s arrangement, exported as a PDF that settles it.
One colour per commercial status
9 colour slots - rename them to match your own paperwork. The legend exports with the PDF.
For getting paid for what you did
The drawing is the argument you do not have to have.
Quoted versus done
Two colours, one drawing. The gap between them is the conversation, and it is now a short one.
Variations, visible
Mark extra work in its own colour as it happens, so a variation is documented on the day rather than reconstructed at invoicing.
Professional output, no designer
A clean legended PDF with your project name on it. It looks like the work of a bigger outfit than one van.
Multiple boats, separate files
Every vessel is its own project. No mixing up which yacht had the transom issue.
Nothing to set up
No setup fee, no implementation, no account for the client. Open it and mark up a drawing.
Works on the boat
Offline-capable and tablet-friendly, because the place you need it is exactly where the signal is worst.
