It effectively combines professional invoicing with a high-tech receipt scanner, making it ideal for self-employed professionals today.

Stintly - Invoice & Expenses’ setup process requires no account creation or subscription to get started.

Get into the details fast

Stintly - Invoice & Expenses’ clean UI helps you navigate quickly between time tracking and expense logs. Its receipt scanner uses a local Large Language Model to pull data instantly, while the voice entry feature allows you to record expenses hands-free. These features, combined with the recent addition of 85 global currencies, make it a versatile companion for digital nomads working worldwide on the go.

Beyond simple billing, it provides solid 1099 tax tools that estimate quarterly liabilities in real time. It automatically maps expenses to Schedule C categories, simplifying the preparation for tax season. You also benefit from the on-site signature capture for project estimates, allowing for a professional workflow that bridges the gap between digital management and real-world interactions with clients at any location in the field.

However, the offline-first model presents some clear hurdles for users who prefer working across multiple desktop systems. It lacks a web-based version, which limits its utility for those who handle complex bookkeeping on a larger screen. Additionally, the heavy reliance on local AI processing may drain battery life faster on older devices, and the manual backup requirement is quite risky for forgetful business owners.

Great in many aspects

Stintly - Invoice & Expenses is a fantastic tool for freelancers who want to manage their finances securely without worrying about monthly fees. Its offline functionality and user-friendly interface make it convenient for those on the go. While it lacks a web version and requires manual backups, its focus on privacy and powerful tax features make it an excellent choice for self-employed professionals.
