- Helpdesk
Ticketing system in Excel: a help desk tracker that works, where it breaks, and what replaces it
A help desk ticket tracker built the right way in Excel or Google Sheets — tickets, an activity log, routing rules and SLA targets — the five places every one of them breaks, and an honest look at the three ways out.
- Retail POS
We had three AI models build the same point-of-sale system. The sale was easy. The refund wasn't.
One twenty-capability POS planner, three frontier coding models, identical brief. All three could ring up a sale. What separated them was everything that happens after it: returns that undo what the sale did, approvals nobody can give themselves, and a production build that actually builds.
- Online store
We had three AI models build the same online store. Taking the order was easy. Taking the money exactly once wasn't.
One fifteen-feature storefront planner, three frontier coding models, identical brief. All three took a real order end to end. What separated them was the money: charging once, never selling the last item twice, and never counting cash that hasn't arrived.

We had four AI models build the same restaurant system. The screens matched. The workflows didn't.
One sixteen-feature restaurant planner, four frontier coding models, identical brief. Three of the four looked finished on day one. We drove all sixteen workflows end to end — selling a dish, splitting a table, refunding a bill, clocking in — and the scores spread from 96 to 58.
- Fleet

- Online store
B2B ecommerce platform: the seven things a consumer store cannot do
B2B ecommerce is not a consumer store with a login on it. Customer-specific pricing, quotes, purchase orders, approval chains and account-scoped catalogues are structural differences, not add-ons — here is what each one requires and why the workarounds fail.

- Accounting
Construction accounting software: why generic books fail a builder, and what to do about it
Generic accounting answers how the business is doing. Construction needs to know how job 214 is doing, and that is a different question. The six requirements no general ledger ships by default, why the workarounds fail, and the four honest routes including building your own.

Open source help desks beat paid ones on some capabilities and lose badly on others — and the split is consistent enough to predict. What the counted evidence shows, and when self-hosting is the wrong answer.
- Learning management
Open source LMS: what self-hosting actually costs, and when to build instead
Self-hosted learning management systems are free to license and expensive to run. The real operating cost, the plugin trap, when open source is clearly right — and the third option between adopting one and paying a vendor.
- Booking

Room and desk booking looks like appointment scheduling and isn't. What you can drop, the four things that actually decide whether people use it, and why internal scheduling is one of the strongest build cases in business software.
