Practical writing for people who pay and get paid on a phone: mobile money, QR payments, cards, remittance costs, agents and how your money is protected.
A till does three jobs: add up the parts, get the tax right, produce a receipt both sides accept. None of them need hardware. Line items, VAT per line, a total nobody types, and staff logins that do not hand over the business.
Every failed checkout loses a customer who had already said yes. Instead of listing eight logos and hoping, the page works out which rails can complete this payment, for this payer, at this minute — and shows only those.
