Permanent QR Codes sells each editable code as a perpetual licence: paid once, no renewal date, no scan or edit cap, and transferable to another account. It is built for things that are printed at scale and stay printed — product packaging, equipment nameplates, manuals and books — and its tooling shows it, with EPS print files, a quiet-zone check before export, CSV bulk updates and a REST API.
Its own comparison of pay-once tools says plainly that QRever costs less for a single code or a small batch. That holds up to 66 codes. Past that, its volume packs fall to a few dollars a code and QRever’s packs don’t, so the answer to “which is cheaper” depends almost entirely on how many codes you’re buying.
