Settings drift. Staff leave, carriers change, apps come and go, and the admin keeps every old choice. These are the areas worth a yearly review, and the ways each one quietly costs money.
Domains and sender email. Every domain you own should redirect to one primary domain. Order emails should come from an address on your own domain, authenticated in your DNS, so mailbox providers trust them and customers recognise the sender.
Staff and collaborator access. Former employees and agencies keep access until someone removes it. Review who holds which permissions, turn on two-step authentication for every account, and make sure the owner account belongs to someone at your company rather than a contractor.
Notifications and policies. Order and shipping emails often still carry template wording and a support address nobody reads, and staff order alerts go to whoever set the store up. Policies generated from a template can promise returns terms your team doesn’t honour, and customers will quote them back to you.
Checkout and payment capture. Manual capture with nobody assigned to it lets payment authorisations expire, and those orders go unpaid. Required fields you don’t need add friction for every shopper.
Shipping zones. Weight-based rates only work when every product has a weight; a variant saved at zero ships at your cheapest rate. One flat “rest of world” price can lose money on every order to a distant country.
Taxes. The review checks that collection is switched on where you’re registered. Deciding where to register, and filing, belongs to a tax specialist.
