POS External Card Payment Logger for EU Cash Register Compliance
The Opportunity
A Shopify POS companion app that lets staff record external card payments cleanly when using third-party bank terminals. It creates a dedicated payment method label, keeps card and cash transactions separated, and helps maintain audit-friendly records for European retail compliance needs.
"Shopify POS users in Europe cannot reliably record manual 'Card' payments when using external terminals, making bookkeeping messy and creating concern about cash-register compliance and transaction clarity."

Detailed Analysis
Proposed Solution
Offer a POS app or POS extension that adds custom tender types such as 'External Card,' syncs them with orders and reports, supports region-specific receipt labels, and exports clean transaction logs for accounting and compliance workflows.
Target Audience
Brick-and-mortar Shopify merchants in Europe, especially France and other markets using external payment terminals and POS compliance requirements
Competitive Landscape
Custom payment methods in Shopify POS, accounting/POS workaround apps, some POS integration tools
Implementation Notes
Use Shopify POS UI extensions or POS app capabilities to add custom tender buttons, persist payment metadata to orders, support external terminal reconciliation, generate reports that separate cash and card, and provide localized naming for EU workflows; verify compatibility with regional POS constraints and receipts.
