Built for how contractors work

Deposits and stage payments

Split an estimate into a deposit and milestones. The schedule always adds up to the total.

Accepted online, billed on the spot PRO

Your client accepts the estimate on its web page and Sumocat creates the deposit invoice.

Materials as expenses

Scan the supply store receipt and the amount, store and date fill in, so job costs stay with the job.

Questions

Something else? Write to support@sumocat.app.

Can I take a deposit before starting a job?

Yes. Add a payment schedule to the estimate with a deposit due on acceptance, then milestones for the rest. Each part becomes its own invoice when it is due.

Can my client sign off on the estimate online?

With Sumocat Pro, your client opens the estimate link and taps Accept. Sumocat records the date and time and creates the first invoice.

Does Sumocat handle change orders?

Edit the estimate before it is accepted, or add a new invoice for extra work. Accepted estimates are locked so the agreed scope does not change under anyone.

Add it up. Send the invoice.

Sumocat is free on iPhone, with no account needed to start.
