Marketplace seller software selection: five UK compliance gates, covering CMA consumer rules, product safety, HMRC VAT records, cloud security and data exit.
No marketplace seller software tool is ranked here. A named candidate pool must clear six gates: entity, offer data, privacy, security, contract and exit.
Use ninety days as reversible marketplace planning checkpoints for evidence, synthetic tests, specialist gates, rollback and a bounded decision.
Plan marketplace seller software in England around one merchant job, using GOV.UK order duties, VAT invoice rules, OPSS safety checks and NCSC access tests.
