A simple invoice app, for the way you actually bill

How it works for your kind of work

Same app, different jobs. Each of these covers what that trade actually puts on an invoice, and where the sharp edges are.

• House cleanersRecurring clients, one-off deep cleans and add-ons priced separately — billed before you leave the driveway.
• HandymenLabor plus materials, small jobs that stack up in a day, and the ones you have to look at before you can price.
• ContractorsPriced scope up front, a deposit on the invoice, and documents that still line up when the job changes halfway through.
• FreelancersBilling clients who have an approvals process, a PO number, and a payment run you have to fit into.
• PhotographersA quote before the date is held, a deposit that shows on the final invoice, and line items that separate shooting from everything after it.
• PlumbersCall-out fees that convert into the job, parts off the van, out-of-hours rates, and three faults at one address on one document.
• ElectriciansFault-finding billed by the hour, installation billed per device, and staged jobs where rough-in and trim are months apart.
• LandscapersA month of visits on one document, seasonal work priced whole, and materials that arrive by the yard rather than the item.
• PaintersPriced by the room and the surface, with prep as its own line, a materials deposit up front, and the balance at the end.
• TutorsSessions billed by the month or bought as a block, taught to a student and paid for by a parent, with the cancellation rule on the document.
• ConsultantsThe invoice is an artefact of the engagement letter — phase, days, cap, and reimbursable expenses kept separate from fees.

If you got here by ruling something out

Plenty of people arrive at this looking for what an invoice app doesn’t make them do.

• Invoicing on iPhoneWhat an invoice app built for a phone — rather than a shrunken web app — actually feels like to use.
• Without accounting softwareWhere the line between “I need to bill someone” and “I need a bookkeeping system” actually falls — and how to tell which side you are on.
• Without payment processingWhat it means for an invoicing app to have no processor attached, and when that is the right trade.
• Without invoice limitsWhy the free tier of almost every invoicing app stops at three or ten invoices a month, and what to check before you accept one.

If you would rather read about invoicing itself than about the app, the invoicing guides cover what goes on an invoice, how to number them, and what payment terms mean. Our review research covers what people actually write about the apps in this category, including ours.

If the job is narrower than choosing an app — you have one invoice to write today — the invoice templates set out what goes on the document for a given kind of work, and how to make an invoice on your iPhone covers every realistic way to produce one on a phone, app or no app.
