The systems, running.

A website chat widget and the support inbox that answers it, with typing indicators, read receipts and canned replies.

Filterable photo gallery with a full-screen viewer, drag-and-drop upload and drag-to-reorder.

Customers pick a free slot, longer appointments need back-to-back free time, and a slot can never be booked twice.

Ask a question in plain words and get the answer quoted from your own policies, with the source shown.

Card, bKash and Nagad checkout with card checks, one-time-code verification, declines handled and a receipt.

Fill in the details, see the invoice update as you type, then save it as a PDF. Switch it to a receipt once it is paid.

Every payment in one list. Refund all or part of one and the balance, the status and the double-entry ledger all update together.

Every branch and the warehouse on one screen, updating as sales happen. Reserve for pickup, watch stock run low, and send a transfer before it runs out.

What the customer sees from checkout to doorstep, and the dispatch board behind it. Rider location, arrival time, SMS updates and failed deliveries handled.

Traffic, error rate and response time for every service, live. Break something on purpose and watch the alerts fire and clear.

The same application form twice: the way many systems still ask for it, and the way we rebuild it. Try filling in both.

Upload a messy Excel or CSV file. Columns are matched, phone numbers, dates and amounts are cleaned, duplicates merged, and problems flagged before anything is saved.

Sales arriving as they happen: revenue, orders and conversion updating live, by channel and by city.
