The website is designed for straightforward licensing, not surprise fees. Product tiers, purchase links, and prices are still decisions to finalize.
For people who want the essentials of organizing and maintaining book records.
Core catalog-focused capabilities
For independent booksellers managing shelves, receiving, sales, and shop operations.
Expanded bookstore workflows
A transition plan must honor the functionality users already purchased. No silent loss of access.
A temporary outage must not unexpectedly erase entitlement to locally available paid tools. Exact rules remain to be defined.
Future Stripe integration would charge for ISBN Manager licenses, not payments collected by bookstores from their customers.
Final pricing for the proposed website and expanded bookstore offering has not been set here. The pricing page is a structural concept and contains no live checkout.
Preserving existing customers’ purchased functionality is a product requirement. Exact migration, upgrade eligibility, and license rules must be written and verified before commercial launch.
Offline continuity for paid features is a design requirement. The eventual implementation will need locally verifiable entitlements and carefully defined grace/expiry rules. This website concept does not implement or certify that behavior.
