Show Cash on Delivery only when it makes sense

COD refusals are expensive: the courier round-trip, the restocking, the fraud. Most merchants want COD sometimes — under a threshold, in certain cities, for known customers. Native Shopify is all-or-nothing.

Drydock's payment rules share the same condition engine, simulator, versions, and rollback as its shipping rules — one safety workflow for every checkout surface.

Test first. Undo after. Always.

Drydock runs every draft rule against a synthetic checkout — real products, any address, any customer — and shows a trace of every condition with the actual values compared. Save good scenarios as test cases and they re-run on every publish, so a rule that changes an outcome gets flagged on the publish screen instead of at your checkout. Every publish is an immutable version with a diff, and restoring a previous version is one click.
