The client says "while you are here, can you also...". Now you can price it, show it and get a signature before you pick up a tool.
Write the slip
- One ticket per extra: a short title, who asked for it, a reference (RFI, PO or change number) and what was done.
- Add labor, material, equipment and other lines with quantity, unit (hr, day, ea, m, ft, m2, ft2, kg, lb, L, gal, lot) and rate.
- Markup and tax are worked out for you. Set the usual percentages once per job and change them on any ticket.
- Up to three photos per ticket, with arrow, circle and pen markup.
Get it signed
- The client or general contractor signs with a finger on the phone. Your foreman signs too.
- Mark the ticket Draft, Sent, Signed, Approved or Rejected so the whole job board shows where the money is.
Send a clean PDF
- One page per ticket with your lines, totals, photos and signatures. Share it with any app on the phone.

Not legal or accounting advice
ChangeSlip helps you write down and price extra work. Check your contract for how change orders must be written, approved and billed. A finger signature on a phone may or may not be accepted under your contract.
Where it lives
Jobs, tickets, photos and signatures stay in this app's private storage on the phone. No ads, no accounts, no analytics. A PDF or spreadsheet leaves the phone only when you tap Share.
