For Builders
Tools we built for our own jobs.
We write software for the problems we run into on site. These are the tools we use at Marblehead Carpentry, open to anyone in the trades.

Invoice and estimate in minutes
Professional PDFs with your logo, line items, tax, credits, and receipt photos. Duplicate any document into a new draft.
Optional job-site time tracking
Turn on a geofence at the client address and billable labor rolls into the invoice as man-hours. Location stays on your iPhone.
Bulk materials from receipt photos
Import a stack of supplier receipts at once. On-device OCR groups them by day, applies optional markup, and merges them into line items.
Books that stay tax-ready
Transactions, chart of accounts, mileage, profit and loss, and categories mapped to common tax lines.

Job walkthroughs
Scope Capture
A scope of work is only as good as the walkthrough behind it. Scope Capture turns a site visit into a numbered, photographed, measured document before you are back in the truck.
Start a project
Name the job and add the client and address.
Capture each item
One scope item per repair or build, each with its own photos.
Mark measurements
Draw a line on the photo and label it with the dimension.
Dictate the notes
Talk through what you see instead of typing on a ladder.
Stair Calculator
From total rise to a cut stringer.
Type measurements the way you read them off the tape. Get a drawing to scale, the framing square settings, and a check against Massachusetts or IRC limits.
