Overview

Smart Profit: Invoices & Estimates, found at smartinvoices.app, is an AI-powered invoicing app for iOS and Android. It helps freelancers, contractors and small businesses create invoices and estimates and keep their finances organised. The same developer also offers a Smart Receipts app.

Free online invoice maker

The website includes a free invoice generator that creates professional PDF invoices instantly with no sign-up. You add your logo, signature and line items, then download the invoice in seconds. This is handy when you need to bill a client quickly from a computer.

The mobile app

The app lets you create, organise and send invoices, track which invoices are paid, and manage digital records. The site says it also helps with tax preparation by keeping invoices organised. AI features help create invoices faster and keep finances in order.

Why choose it

The site lists four reasons: simplicity and speed, with an interface anyone can use regardless of technical skills; flexibility; automation; and data security.

Pricing

The online invoice maker is described as 100 percent free. The mobile apps are free to download from the App Store and Google Play; check the store listing for any in-app purchases or subscriptions.

Who it suits

It suits freelancers, tradespeople and small business owners who send a modest number of invoices and want a quick, simple way to produce them on a phone or in the browser, without full accounting software.

Things to consider

Make sure your invoices include the details required in your country, such as tax numbers, VAT rates and sequential invoice numbers, as a generic template may not cover local rules. If you use an accountant, check that the app's exports work with their tools. For growing businesses, full accounting software may eventually be needed to handle bookkeeping, payroll and tax filing. Read the privacy policy, since invoices contain client data. The free web generator is an easy way to test the layout before installing the app.

For people who only need to bill a few clients a month, a simple free tool like this can be enough. It removes the need for spreadsheets or word processor templates, and keeps all invoices in one place for later reference.
