If you run a small trade or a one-person business and your billing lives in a notebook or a word processor, Invoice Maker - InvoiceBase is the sort of app that fits the gap. The developer, Gulooloo Tech Co., Ltd., built it for freelancers, contractors and small business owners, and it covers the basics of quoting a job, turning that quote into a bill and keeping track of who has paid. It has been installed over a million times and holds a 4.9 average across more than 63,000 ratings, which suggests it lands well with the people who use it.
What I like about the premise is that it treats the estimate and the invoice as two stages of the same job rather than two separate documents. You quote, the client agrees, and the quote becomes the bill without retyping anything. For anyone who sends a handful of invoices a week, that alone is the reason to consider it.
From quote to bill without retyping
The feature the developer leads with is the estimate maker, and the way it pairs with the invoice side is the most useful part of the app. You can build an estimate, send it to a contractor or client, and then convert it into an invoice once the work is agreed. That flow matters for trades where the price is settled before the job starts and the bill follows weeks later.
The app also handles the arithmetic. The developer says it does the complex calculations for you, which is the sort of thing you want from a billing tool: line items, quantities and totals worked out without a spreadsheet open in another window. There is a real-time preview while you build a document, so you can see the finished layout as you go rather than exporting to check it.
The three-step description the developer gives is short: create the invoice, add the details, save and send. That is the right shape for an app like this. If you can fill in a form, you can produce a bill.
Templates, statuses and the paperwork around them
Presentation is handled through a set of invoice templates, and you can add your company logo and website so the finished document carries your branding rather than looking like a generic form. For a sole trader who wants to look established, that is worth the few minutes it takes to set up once.
Payment tracking is the other half of the job, and the app gives each invoice a status you can change as money comes in. At a glance you can see what is outstanding and what has been settled, which is more reliable than remembering which client paid last month. The developer describes this as clear status for each document, and the overview is the part I would lean on most once a few jobs are in flight.
Around the document itself there are the details that decide whether an invoice is usable: multiple currencies, and control over number and date formats, so a bill reads correctly for the client receiving it. You can add a signature to an invoice, which suits trades and services where a signed acceptance is part of the deal.
When the document is ready, you can export it as a PDF or an image, print it, or send it by email from the app. Saved clients and frequently used items can be reused, which cuts the repetitive typing on repeat jobs.
What it expects from you
It does offer in-app purchases, so the app is not entirely without cost if you decide you want more than the free experience provides. The free download is the starting point, and you can decide from there.
The requirements are modest. You need the client details and the line items to put into a document, which is the same information any invoice needs. There is nothing here that asks for an accounting background, and the app is built for people who bill occasionally rather than for a finance department running a ledger.
The recent update added country-specific invoice adaptations for India, the UK, Canada, Germany and France, along with email sending templates. If you bill clients in one of those markets, that is a meaningful addition; if you do not, it changes little for you.
Getting the most out of it
The habit that pays off with an app like this is setting up your reusable pieces early. Enter your logo, website and the items you bill for most often, and the work of creating an invoice drops to picking a client, choosing the items and adjusting quantities. On a repeat job, that is a couple of minutes rather than a fresh document each time.
I would also use the estimate stage properly rather than treating it as a formality. Sending a quote first, then converting it, gives you a record of what was agreed and saves you rebuilding the same information when the invoice goes out. For contractors who quote regularly, that is the workflow the app is designed around.
Keeping statuses current is the other habit worth forming. The overview is only as useful as the updates you make to it, so marking an invoice as paid when the money lands keeps the picture honest and saves you chasing a client who has already settled.
If you bill in more than one currency or send documents to clients in different countries, set the currency and format per document rather than leaving a default in place. The app supports that, and it avoids the awkward follow-up email about a bill that reads oddly.
A billing tool for people who bill on the move
Invoice Maker - InvoiceBase is a focused app. It creates estimates and invoices, converts one into the other, tracks payment status and gets the document out as a PDF, an image or an email. It does not try to be a full accounting suite, and for a freelancer or a small trade that is usually the right scope.
The combination of a free download, no ads and a strong rating makes it an easy one to try if you are currently producing invoices by hand. The in-app purchases are the one thing to keep in mind, since the app is not a purely free product.
If your billing is occasional and your needs are simple, this looks like a good fit. If you need inventory, payroll or detailed books, you are looking at a different class of software.
The short verdict
A focused, ad-free invoice and estimate maker that suits freelancers and small trades who bill clients from a phone.
