01An admin panel your team works in
One screen for the people who run the business. The record, and the buttons that change it, in the same place — refund the customer, resend the invoice, approve the artwork, mark it shipped. Not a report that tells somebody to go and do it somewhere else.
02Controls your customer service team can actually use
The things support gets asked for twenty times a week, made into buttons a non-technical person can press safely: reissue a receipt, extend a trial, correct an address, look up what was really sent and when. The alternative is a developer doing it by hand in a database, which is slow on a good day and a disaster on a bad one.
03A portal for your customers
The same system seen from the other side, with its own login and nothing else visible. They approve the proof, ask for the change, see where the order is, download the receipt — instead of calling to ask, which is a job for somebody either way.
04The back end underneath both
Payments, invoicing, email that sends reliably, files stored where they can be found, a log of who did what and when. The unglamorous half, and the half that decides whether the rest can be trusted.
