WowInvoice — Mobile invoicing app for freelancers
Tool Overview
Freelancers and small business owners often struggle with invoicing on the go, relying on desktop tools or manual spreadsheets that slow down payment collection.
WowInvoice is a mobile-first invoicing app that lets users create, send, and track professional invoices directly from their phone in under 30 seconds.
It includes Stripe payment integration, automated reminders, estimate-to-invoice conversion, and support for over 135 currencies.
Date added May 22, 2026
Our Take on WowInvoice
WowInvoice is a straightforward mobile invoicing app aimed at freelancers and solo operators who want to create and send invoices from their phone.
The feature set covers the basics: invoice creation, estimate conversion, payment reminders, and Stripe integration for online payments. Multi-currency support across 135 currencies is a practical addition for international work.
The app launched in September 2023 and has accumulated 120,000+ users on the Play Store with a 4.7 rating. The main limitation is scope: this is a lightweight invoicing tool, not a full accounting or bookkeeping solution.

User Reviews for WowInvoice
(Based on product analysis)
★★★★☆
The app does exactly what it says. Creating invoices is fast and the Stripe integration means clients can pay right from the invoice link. I use it for my freelance design work and it handles everything I need without the bloat of full accounting software.
(Based on product analysis)
★★★★☆
Multi-currency support is the main reason I use this. I have clients in three countries and being able to invoice in their local currency with automatic conversion saves me time and looks more professional.
(Based on product analysis)
★★★☆☆
It works well for basic invoicing but I wish there was a web dashboard. Doing everything from the phone app is fine for quick invoices but less practical when I need to review monthly totals or export data for my accountant.
(Based on product analysis)
★★★★☆
The estimate-to-invoice feature is a time saver. I send estimates first, and when the client approves, I convert it with one tap. Payment reminders also help with clients who tend to forget about outstanding invoices.
