Invoice HopA water heater call, invoiced in one sentence
You finish a tank flush and a new anode rod at 4:40 PM. Before you start the truck, you hold the mic and say the job. The draft comes back with labor and parts on separate lines.
- Say: “Invoice Mike Johnson, 3 hours labor at 95 plus 62 in parts, due in two weeks.”
- Check the yellow fields. Add a photo of the old rod and a note about the parts warranty.
- Tap Send and pick Text. The message goes from your own phone.
| Item | Qty | Amount |
|---|---|---|
| Labor | 3 hr × $95.00 | $285.00 |
| Parts | 1 × $62.00 | $62.00 |
| Total | $347.00 |
Example only. Your rates and items come from what you say and your saved list.
What plumbers use most
The parts of Invoice Hop that match how a service call actually goes.
Saved items with units
Keep your service call, hourly labor and common parts in a list with units like hr and ea. Start typing and the price fills in.
Estimate to invoice
Send an estimate on the first visit. After the job, one tap turns it into an invoice with the same lines.
Photos and signature
Attach up to 10 photos and get the customer’s signature on your phone when the work is done.
Common invoicing mistakes on service calls
- One line for everything. “Repair: $347” invites questions. Split labor and parts so the customer sees what they paid for.
- Waiting until evening. Invoices sent from the job get looked at while the customer still remembers the work.
- No way to pay on the invoice. List every method you take. A Zelle address with a Copy button gets used more than “call to pay.”
Plumbing invoice questions
Can I invoice labor by the hour and parts separately?
Yes. Each line has a quantity, unit and price, so labor can be hours times your rate and parts can be listed one by one. Save common parts and service calls to your item list to reuse their prices.
Can I turn an estimate into an invoice after the job?
Yes. One tap turns an estimate into an invoice with the same customer, items and prices. Change anything that came up during the job before you send it.
Can I add sales tax?
Yes. Set your tax name and rate once, and choose whether tax applies to the whole invoice or only to some lines, such as parts. Tax rules vary by state, so check with your accountant.
Can I attach photos of the repair?
Yes. You can add up to 10 photos to an invoice, for example the old part next to the new one.
