Invoice Maker - MobileBiz Pro

Review by eFreeware

Most invoicing apps assume you have a signal. MobileBiz Pro takes the opposite approach: the developer says no internet connection is needed to create an invoice or reach your records, and the business data stays on your phone rather than in the cloud. That single design choice shapes everything else about the app, from the way it handles backups to the kinds of workers it suits.

It is built for people who bill for their time and materials away from a desk. Electricians, plumbers, HVAC technicians, landscapers, cleaners, IT consultants, auto detailers and independent designers all appear on the developer's own list of intended users, and the feature set reads like it was assembled with those trades in mind. If your working day happens in a basement, a rural lot or a client's garage, the offline angle is the reason to pay attention.

The app has been around a long time, first released in November 2010, and it currently sits at a 3.6 average from just over 2,000 ratings with more than 10,000 installs. Those numbers describe a mature, modestly sized tool rather than a breakout hit, which is roughly what I would expect for software aimed at working tradespeople.

Where it fits in a working day

The core loop is familiar: build an estimate or quote, get the job, then turn that estimate into an invoice. The developer describes the conversion as a single tap, which matters when you are standing in a driveway writing up a job you just finished. Digital signatures can be captured on site, so a customer can approve work before you pack up.

Once the invoice exists, you can send it by text message, or email and print it as a PDF if you have the Plus tier. Chasing late payers through statements is a Plus feature. Recording payment is more open: cash, check, card and bank transfer are all supported, and you can put a PayPal link on an invoice so a customer can pay online.

Repeat clients are handled with recurring invoices, and aging reports at 30, 60 and 90-plus days give you a running view of who owes what. For a one-person operation, that combination covers most of the administrative work that otherwise ends up on a kitchen table at the weekend.

The app is available in English, Spanish, French, Italian, German and Portuguese, with other languages possible through editable templates.

Products, stock and price levels

Inventory is treated as a first-class part of the app rather than an afterthought. Barcodes can be scanned for item entry and stock takes, and stock levels adjust automatically as sales are recorded. That is aimed at anyone who sells parts or materials alongside labor.

Price levels for wholesale, retail or VIP customers let you keep separate rates without maintaining duplicate product entries. The app also tracks customer balance, invoice cost and profit, so a job's margin is visible rather than something you reconstruct later.

For someone running a small distribution or retail operation alongside a service business, this is the section of the app that earns its keep. For a pure consultant who bills hours, it is there if needed and easy to ignore.

The reporting side

Ten reports are built in, covering sales by period, item and customer, plus customer profitability, aging, payments, inventory, out-of-stock, monthly tax and profit and loss. Reports can be exported to CSV or to QuickBooks for an accountant, and customer and product data can be imported from QuickBooks or CSV files.

The developer also promises no record caps: unlimited invoices, estimates, customers, products and reports, with no transaction fees, so payments you collect stay with you. That is a notable position for an invoicing tool, where per-invoice limits are a common frustration.

Customization runs deeper than most small-business apps bother with. PDF templates take your logo, fonts, colors, page sizes and watermarks; custom fields cover data the standard forms do not; and tax handling supports single tax, dual tax or tax-inclusive pricing, along with multiple currencies and date formats.

Multiple businesses can be run from the same install, each with its own customers, products, invoices, reports and settings. That is a genuine convenience for anyone operating two or more ventures under different names.

What the app costs

The app is free to download and carries no ads. It does offer in-app purchases, and the developer has moved the product to a subscription model, explaining that the change funds ongoing development, faster fixes and support. The app has been maintained by the same team for over fifteen years, with no stated plan to stop.

A Plus tier sits above the free experience. Plus brings PDF invoices by email or print, statements, emailed receipts, report PDFs and payment-portal links, along with receipt-photo expenses, invoice attachments, Drive backup, QuickBooks export, income statements and photo sync across devices.

Since the business data lives on your device rather than in the cloud, keeping a backup routine running is the sensible habit regardless of which tier you use.

Recent updates have added advanced CSV export for sales transactions, separate PDF filename settings for each sale type, and a fix for signatures not appearing on receipt printouts.

How it compares with the alternatives

The obvious comparison is a cloud-first invoicing service, the kind that syncs everything to a browser dashboard and charges a monthly fee. Those tools tend to be stronger for teams and for anyone who wants to check figures from a laptop. MobileBiz Pro trades that reach for local ownership and offline reliability.

A general accounting package is the other direction. It will go further into bookkeeping, payroll and year-end work, but it is heavier than most field workers need on a phone. MobileBiz Pro stops at invoicing, estimates, sales orders, payments, inventory and reporting, which is a deliberately narrower scope.

Spreadsheets remain the free option, and they are flexible. A dedicated invoicing app makes sense when the paperwork has to happen in the field, not at a desk.

A practical pick for trades that bill on site

MobileBiz Pro is a mature, focused tool for getting invoices out of the way while you are still on the job. The offline design, the estimate-to-invoice conversion, on-site signatures and the breadth of the reporting make it a strong fit for contractors, field service workers and small operators who bill for labor and materials.

The trade-offs are real. Some of the most useful sending and expense features sit behind the Plus subscription, and the app's data lives on your device, which puts the responsibility for backups on you. The 3.6 rating suggests a user base that is satisfied but not ecstatic, which is worth weighing if you are choosing between this and a cloud service.

If your work happens where the signal does not reach, or if you would rather your client records stayed on hardware you control, this is one of the more complete options in its category. For the solo operator or small crew, MobileBiz Pro covers the ground.
