Free: manual recent/historical reports and continuation, product/order/refund cost review, manual payment/shipping expenses, simple global defaults, checks, reviewed manual imports and guarded undo. Pro: reusable conditional payment/shipping expense rules. Saved rule configuration is retained when Pro is absent; recorded snapshots keep identical arithmetic. Unrecorded expenses needing unavailable rules require manual review. Install Free 1.10.18 before Pro 1.10.18 without uninstalling. No grandfathering.
