## What is Pay Day?

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 for all businesses (2026), with Germany, France (2027), Poland and more rolling out next. That means 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.

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.
