PYMNTS hierarchy of convenience · prime 383 · v1.0

You already sent the invoice. It's sitting in someone's AP queue. fallap rewrites it as a one-click-pay landing page — the format that gets paid first. Paste the invoice below, hit rewrite, email the result as an HTML attachment.

This is what AP sees when they open the file you email them. One screen. One button. Pre-populated amount and reference. Email it as an attachment, host it anywhere, or paste the link into WhatsApp.

Architecture · sovereign single-file · doctrine ▾

◊ One HTML file · <400KB · vanilla JS · no frameworks · no build step · works from file://

◊ Storage: IndexedDB primary · localStorage fallback · drafts of rewritten invoices and your payment-method settings stay on this device

◊ PDF parsing: minimal vanilla text extractor — pulls BT...ET blocks from PDF content streams. Lossy for image-based PDFs (most modern ones are). Falls back gracefully to paste-text.

◊ QR code: inline ~2KB vanilla encoder (no qrcode.js bloat) · numeric / alphanumeric / byte modes · ECC-L · version 1-10

◊ Mesh: BroadcastChannel('fall-signal') · prime 383 · emits invoice_rewritten events for fallcore / fallmesh consumers

◊ Konomi shim: free = 3 rewrites/month + watermark · Pro = unlimited + branded landing + bulk + API hook

◊ Companion to fallinvoice (generates new) · fallap rewrites what you've already sent
