Most invoice apps make a pretty PDF. Pay Day makes one your tax authority's system can actually read.
The EU is switching to mandatory electronic invoicing. Belgium requires every VAT-registered business to send and receive structured e-invoices over Peppol since 1 January 2026, with fines for a plain PDF. France went live on 1 September 2026, and small businesses must issue e-invoices from 1 September 2027. Germany follows in 2027 and 2028, and EU-wide cross-border e-invoicing arrives in 2030. A normal PDF is no longer enough. Pay Day is built for exactly this moment, on your iPhone, with no desktop software and no monthly bookkeeping suite.
FREE, AND GENUINELY GENEROUS
- Unlimited invoices and estimates. No per-document limit, no watermark, no "upgrade to export."
- Unlimited clients, your logo, and multi-currency with European Central Bank reference rates.
- A real EN 16931 VAT engine: standard rates, intra-community reverse charge, zero-rated and exempt lines — with a correct, properly rounded VAT breakdown on every document.
- Works fully offline. Bill from a job site, a train, anywhere.
- No account required to start. Open the app and you're invoicing.
- Your country's e-invoicing rules on the dashboard: what is mandatory, since when, and what to set up.
PRO — REAL E-INVOICE COMPLIANCE, NOT JUST A PDF
- Factur-X / ZUGFeRD e-invoices: a single hybrid file that looks like a clean invoice to your client and carries embedded EN 16931 data a tax authority's system can read automatically. Independently validated as a valid PDF/A-3 with valid EN 16931 XML.
- Peppol delivery: send your invoice straight into your client's accounting system over the EU's official network — no email attachment, no portal logins.
- Recurring invoices: set it once, get paid every month.
- Your branding: logo, accent colour, and templates that look like your business, not a template.
- Live VAT validation: check every client's VAT ID against the EU VIES service before you issue.
CREDIT PACKS — PAY ONLY FOR WHAT YOU SEND
- Top up with consumable credit packs that cover each Peppol network send (we pass through the real per-send cost rather than padding a subscription).
- The same credits power optional AI helpers: snap a photo of a quote or receipt and turn it into line items, type a rough description and let it draft the lines, or generate a tactful payment-reminder email for an overdue invoice. AI actions cost a few credits each and are entirely optional — the app is complete without them.
WHO IT'S FOR
Freelancers, consultants, designers, developers, and small businesses across the EU who invoice other businesses and need to be ready for e-invoicing mandates — without paying for a heavyweight accounting platform.
HONEST PROMISE
The free app is a complete invoicing tool, not a trial. We only ask you to pay where it genuinely costs us or genuinely earns you compliance: structured e-invoices, network delivery, automation, and AI. No fake urgency, no nagging, no surprise limits.
Pay Day Pro is an auto-renewing subscription, monthly or annual with a 7-day free trial. Peppol network sends are metered separately via consumable credit packs on every Pro plan. Payment is charged to your Apple ID; subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel anytime in your Apple ID settings. Credit packs are one-time purchases.
