Invoice Maker - Invoice Fly

Review by eFreeware

Most invoicing tools assume you are sitting at a desk with a laptop open. Invoice Fly is built around the opposite idea: you write the invoice on the phone you already have in your pocket, send it, and get told when the client opens it. The developer, Labhouse Mobile, lists it under Business on Google Play and describes it as being for small businesses, freelancers and contractors.

That framing is the whole pitch, and it is a narrow one on purpose. If your billing happens in the field, at a client's address, or in the gap between two jobs, the appeal of assembling and sending a document without going back to a computer is obvious. The app has been installed more than a million times and holds a 4.7 average from 137,490 ratings, which suggests the basic job is being done well for a lot of people.

It is free to download, carries no ads, and offers in-app purchases. It was released in late December 2022, and the most recent update, from early October 2026, brought interface work and general performance fixes rather than new features.

What goes into an Invoice Fly document

The core of the app is a form that flexes to fit the job. The developer says you can configure as many details as you need, and the list is longer than a bare invoice usually carries: payment information, taxes, withholding, due dates, discounts, extra images and a signature. A cleaner can bill an hourly rate with tax added per line; a contractor can attach a photo of completed work and a signed sign-off.

Discounts and taxes can be applied either per item or to the total, which matters more than it sounds. Plenty of small businesses mix taxable materials with non-taxable labor on the same document, and having that choice per line rather than only across the whole invoice saves a second pass with a calculator.

There is a short four-step flow the developer lays out: create the invoice, pick the client from your contacts, add items and prices, then save and send. The claim is that an invoice takes under a minute to produce. I would treat that as the target rather than a promise, since the time depends on how much detail a given job needs, but the shape of the process is genuinely simple.

Templates are part of the setup, so the document that reaches your client can look like it came from a business rather than a phone.

Estimates that turn into invoices

The feature I find most useful in principle is the estimate-to-invoice conversion. You quote a job as an estimate, the client agrees, and the developer says you can generate the invoice from it with a tap. Anyone who has retyped the same line items twice, once to quote and once to bill, will recognize why that matters.

It also keeps the two documents consistent. When the invoice is built from the accepted estimate rather than written fresh, the prices the client already saw are the prices on the bill, which removes a common source of awkward back-and-forth.

The same machinery covers bills and receipts, so a single app can handle the paperwork on both sides of a transaction rather than just the outgoing invoice.

Sending, tracking and knowing it arrived

Invoices can be shared or printed straight from the phone. Sharing covers the usual routes a small operator would use to get a document to a client, and printing matters for anyone who still hands over or mails paper copies.

The tracking side is where the app tries to do something a PDF attachment cannot. The app can tell you once a customer has opened your invoice, according to the developer. For a freelancer chasing a late payment, knowing the document was opened is a different kind of information from knowing it was sent, and it changes how you word the follow-up.

Clients are pulled from your phone's contact list, which cuts down on typing and on the small errors that come from entering an email address by hand.

Reports, syncing and support

Income tracking is handled through reports. That is a modest version of bookkeeping rather than a replacement for accounting software, but for someone who wants a running view of what has been billed without exporting anything, it is the right scope.

Signing in with the same account syncs the app across your devices, so a phone used on site and a tablet kept at home see the same records. That matters for anyone who does the work in one place and the admin in another.

Support is available around the clock. Since the app is free with optional purchases inside it, that is a reasonable thing to weigh when comparing it with paid tools that charge a monthly fee and may or may not answer quickly.

The latest release notes mention interface improvements, performance upgrades and bug fixes, so the current version is a maintenance pass on an app that has been out for a few years rather than a rebuild.

What the app asks of you

The trade-offs here are mostly about scope and cost. Invoice Fly is a phone-first tool for producing and sending documents, not a full accounting system, so anyone expecting ledgers, bank feeds and year-end reporting will be working outside what it is built to do. The reports cover income, which is the part a solo operator checks most often, and that appears to be where it stops.

The app itself is free and shows no ads, but it does offer in-app purchases. It makes sense to treat the free download as a look at the workflow and check the current options in the app before committing to it as your main billing tool.

The tracking notification, by definition, depends on the client's side of the exchange happening.

There is also a small learning curve in the detail the app exposes. Per-item taxes, withholding and discounts are exactly the options that make the output correct, and they are also the options that take a few minutes to set up the first time you use them.

Who gets real use out of it

The clearest fit is someone who bills clients directly and does the paperwork themselves: a freelancer, a contractor, a tradesperson, a consultant. The estimate-to-invoice path, the contact-list client setup and the open notification all point at a workflow where one person handles quoting, billing and chasing.

Small businesses with a handful of people sending invoices from their own phones are the other obvious group, particularly where the same account is used across devices so the records stay in one place. The template and signature options mean the output can carry a company's identity without a separate design step.

Where it fits less well is in a business with a bookkeeper, an accountant and a formal chart of accounts. Income reports are useful, but they are not a general ledger, and the app is not presented as one.

A phone-first billing tool worth trying

Invoice Fly does one thing with more care than most general-purpose document apps: it gets a professional invoice out of a phone quickly, with the tax, discount, signature and attachment detail that makes the document stand up, and it tells you when the client has seen it. That combination is why the install count and the 4.7 average are where they are.

The caveats are worth stating plainly. It is free with purchases available inside, and the reporting stays at the income level rather than reaching into full accounting. It suits freelancers and small businesses that want to send invoices, estimates, bills and receipts and keep an eye on income.

For a freelancer or contractor who wants to quote a job, convert it to an invoice, send it from the phone and know when it landed, it is a straightforward install. The free download makes that an easy thing to judge for yourself.
