FAQ
Common questions
Is Invoice Master free?
Yes. The app is free to download on iPhone, iPad and Android and includes a free plan for invoices and estimates. The online invoice generator on this page is completely free with no account. An optional Pro subscription — monthly, yearly or a one-time lifetime purchase — removes limits and unlocks premium templates, multiple business profiles, multi-currency and advanced reports.
Is there an app for iPhone and Android?
Yes. Invoice Master is on the App Store (iPhone and iPad) and Google Play (Android). The app adds saved clients, a product catalog, estimates, payment tracking, reminders and reports.
Can I send invoices as PDF?
Yes. Every invoice and estimate in the app exports as a PDF you can share by email, WhatsApp or any messaging app. On the web, use 'Print / Save PDF'.
Does the app work offline?
Yes. Your data is stored on your device, so you can create and manage invoices without an internet connection, with optional external backup.
Is my invoice data private?
The web generator runs entirely in your browser — no invoice data is sent to our servers. The mobile app stores everything locally on your device.
Which languages are supported?
English, German, Spanish, French, Italian, Japanese, Portuguese and Chinese.
