Open the job
The estimate you already sent lives on the job. Tap convert, and the invoice is built with the same line items and totals the client approved.
Invoicing
Invoice software built for contractors in the field.
Send the invoice before you leave the driveway. Crewkat turns your approved estimate into a clean, professional invoice — and keeps track of who has paid and who hasn't.

What it does
From finished job to sent invoice in about a minute.
Most contractors invoice at night, from memory, days after the work is done. Crewkat keeps the numbers with the job, so the invoice practically writes itself — line items, totals, tax, and discounts already added up, ready to send as a polished PDF or a link your client opens on their phone.
- Convert an estimate to an invoice in one tap. Everything the client approved carries over — no retyping, no mismatched totals.
- Professional PDFs. Clean, branded templates that look like they came from an office, not a truck cab.
- Payment tracking. Record payments as they come in — cash, check, or transfer — and see the remaining balance at a glance.
- Know where every dollar stands. Sent, viewed, partially paid, overdue: invoice status is always one glance away.
- Client link included. Clients open their invoice from a secure link — no account, no app to install. See the client portal.
How it works
Three steps, standing in the driveway.
Adjust and send
Add a final line, a discount, or tax if the job changed. Send the PDF or share the client link — your customer sees a clean invoice with your business name on it.
Record the payment
When the check lands or the transfer clears, record it against the invoice. Partial payments show the balance still due, so nothing slips through the cracks.
Built for small crews
Made for the way contractors actually bill.
Progress payments on a remodel, a deposit at signing, the balance at completion — Crewkat handles partial payments without a workaround. Duplicate an invoice when the same client books the same work again, and keep every invoice tied to its job so the paper trail is never a scavenger hunt.
If the scope grows mid-job, the estimate's optional add-ons your client ticked flow straight into the invoice — the agreed price and the billed price match, every time.
Fewer awkward calls
Clients always know what they owe.
Your client gets one link where the invoice, the amount, and the balance are plain to see. When they ask "what's left on the Johnson job?", the answer is on your phone in seconds — no digging through texts or a glovebox full of carbon copies.
Estimates, invoices, and signed contracts all live in the same place, so the whole money story of a job stays together.
Common questions
Invoicing, answered.
Can I invoice from an estimate I already sent?
Yes — that's the normal flow. Open the approved estimate, convert it, adjust anything that changed, and send. The optional add-ons your client accepted are included automatically.
How do clients pay?
Clients pay you the way they already do — check, cash, or transfer — and you record the payment in Crewkat to keep the balance current. Invoice links are for viewing and approving documents.
Is invoicing included in the free plan?
Yes. The free plan includes 3 documents a month; Premium removes the limit for $19/month. See pricing for the full comparison.
