EasyInvoice: Invoice Generator by Felix Brix is an iPhone application designed for freelancers, consultants, and small business owners to produce branded invoices and estimates on the go. The app generates PDF invoices and converts tracked time and scanned expenses into billable items, while supporting European e‑invoicing formats for compliant exports. Built-in OCR receipt capture, VAT per-line calculations, multi-currency handling, and iOS contacts import make it a compact mobile-first invoicing solution for solo professionals.

What is EasyInvoice used for in a working day?

EasyInvoice positions itself as a mobile invoicing and bookkeeping aid for individual professionals, with core functions that include PDF invoice and estimate creation and a client database import from iOS contacts. The dashboard gives revenue, profit, and open receivable analytics, which supports short reporting cycles. These elements suit solo contractors who need to prepare client-ready invoices and track outstanding receivables without switching to desktop software.

How does the app turn tracked work and expenses into billable output?

The app includes an integrated time tracker and expense manager that convert entries into invoice line items, and its OCR receipt scanner extracts vendor, amount, date, and tax automatically. Tax math is performed per line, with automated VAT, subtotals, and totals, so invoices reflect correct tax treatment. These mechanisms reduce manual entry when turning project hours and receipts into final PDF documents.

Is EasyInvoice compatible with professional invoicing standards and cross-border needs?

EasyInvoice supports electronic invoicing standards required in business-to-business scenarios, specifically ZUGFeRD and XRechnung, and it generates SEPA EPC QR codes and Swiss QR-bills for client transfers. Multi-currency support is built in. The app therefore fits workflows that must produce compliant e-invoice exports and provide QR-based transfer references for European and Swiss clients.

Does the app fit into existing iPhone workflows and what is the learning curve?

The app runs natively on iPhone, iPad, and Mac and requires modern OS levels, which places it firmly in the Apple ecosystem. Importing clients from iOS contacts and on-device OCR reduces setup time, while the dashboard centralizes analytics for quick checks. The developer actively maintains the app and adds features like product catalogs and improved e-invoice compatibility, so users benefit from ongoing refinements without complex onboarding documentation.

Best for mobile-first solo professionals who accept an account-gated feature set

EasyInvoice suits freelancers and small business owners who prioritize on-device invoicing, short reporting loops, and standards-compliant exports; advanced capacity is concentrated behind a Pro access tier, which can constrain high-volume workflows; choose the app when mobile convenience and Apple-native integration matter, and consider alternatives if team-level account controls or enterprise workflows are required.
