Counted, not guessed.
What real products in each market actually ship — and the failure modes AI coding agents hit every time. Build guides, cost breakdowns, and the evidence behind the planners.
- Booking
Salon and spa booking system: the gap-filling problem nobody prices
A salon's booking system is a revenue tool, not a calendar — and the capability that matters most appears in only 13 of 92 live booking systems. What personal services need beyond the floor, why processing time breaks generic schedulers, and what to specify if you build.
- Booking
Patient appointment scheduling software: what a clinic needs that a booking link doesn't do
A booking link and a clinical scheduler look identical and are not. The counted core from 92 live booking systems, the six things clinical scheduling adds, why double-booking is a correctness problem rather than a UX one, and what to specify if you build.
- School
Web-based student information system: hosting, access, and who can see a child's record
Almost every school system is web-based now, so the word has stopped being a distinction. The three hosting shapes and what each means for your IT lead, the access model that actually matters, what breaks specifically in browser-delivered school software, and what building one really involves.
- Learning management
Training tracking in Excel: a template that works, where it breaks, and what replaces it
A training tracking spreadsheet built the right way — people, requirements and a completion log — the five failures that end every one of them, and an honest look at the three ways out when the matrix stops being trustworthy.
- School
Student information system: what an SIS is, what it isn't, and what it has to include
The counted feature list from 46 real school systems, the SIS-versus-LMS distinction that causes most of the wasted money in this market, the guardian data model that quietly breaks migrations, and how to scope one that finishes.
- Restaurant
Restaurant management system: what it includes, and why it isn't one product
The counted feature list from 59 real restaurant systems, the eight venue shapes that need genuinely different software, the three design decisions that quietly decide whether it works in service, and how to scope a build that finishes.
- Retail POS
POS system for small business: what actually matters, counted across 60 real products
Small-business POS is sold on hardware and monthly price, and neither decides whether it works for you. The counted feature list from 60 real POS products, the two controls a small shop needs most and gets marketed least, and the money-path tests to run before you commit.
- Accounting
Nonprofit accounting software: fund accounting is the whole difference
Nonprofit accounting is not ordinary bookkeeping with donations added. Money arrives with conditions attached, and the balance that matters is per fund rather than per account. What that requires, why the class-and-tag workaround fails an audit, and the four honest routes.
- Helpdesk
Using Jira as a ticketing system: what works, what breaks, and when to stop
You already have an engineering issue tracker, so do you need a separate support desk? The five structural differences between tracking work and handling requests, the seat problem nobody costs, and an honest line for when staying put is right.
- Helpdesk
IT ticketing system: what it has to do, counted across 18 real help desks
What a ticketing system is for, the counted feature list from 18 real help desk products, the tell that separates a serious desk from a cheap script, and the three failures that kill self-hosted and self-built desks — email intake, portal spam, and exports you cannot leave with.
- Retail inventory
Inventory management system database design: the schema, and the one column that ruins it
A working database design for an inventory management system — the movement ledger, derived on-hand, PO and stocktake state, and transfers — with the DDL, the constraints that enforce it, and how to migrate a schema that already has a quantity column.
- Learning management
Features of a learning management system: the counted list from 38 real platforms
Not a vendor feature grid — a tally of what 38 real LMS platforms actually ship, ranked by frequency, with the difference between the real version of each feature and the decorative one, and a test you can run in any demo.
- Retail inventory
Custom inventory management software: what you're actually paying for, and when it's the wrong answer
What a development quote for a custom inventory system is really priced on, the operational shapes that genuinely justify one, the questions that separate a good agency from an expensive one, and what changed when coding agents collapsed the typing cost but not the knowing cost.
- 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.
- Restaurant
Cloud-based restaurant POS: what 'cloud' buys you, and what happens when the Wi-Fi drops
Three different architectures all call themselves cloud-based, and they behave completely differently when the connection fails mid-service. What each actually means, the offline test to run before you sign, and what it takes to build one that degrades honestly.
- Retail POS
Cash register vs POS system: the honest line between them
A cash register counts your money; a POS knows what you sold. Which one you need comes down to a single question, plus the four triggers that move a shop over the line, what upgrading really costs beyond the price, and why the register-plus-spreadsheet middle fails.

WMS, inventory management and order management get sold interchangeably and solve different problems. What each actually does, how to tell which you need, and the number that decides it.
- Retail POS
POS system cost: the line that isn't the software
Point-of-sale pricing is quoted as a monthly fee, but the monthly fee is rarely the expensive part. How to work out your real three-year cost, and the number that decides whether building is rational.
- Helpdesk
Open source ticketing system: what you gain, what you give up, and what to check
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
Meeting room booking system: why it needs a fraction of a booking app
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.
- Retail inventory
Inventory management in Excel: a working template, where it breaks, and what comes next
A spreadsheet inventory system that actually works, the five failures that end every one of them, and an honest look at the three ways out — keep it, buy software, or build the real thing.
- Helpdesk
Free ticketing system: where the free tiers stop, and how to test one properly
Free IT ticketing systems are capped on agents, not tickets — which is the cap that matters. What disappears at the free tier, a one-afternoon test protocol, and the point where free becomes expensive.

The honest decision framework — when Square/Lightspeed-class SaaS is the right call, when owning your stock system pays off, and what AI coding agents actually changed about the math (they collapsed the typing cost, not the knowing cost).
- Online store
Why AI coding agents over-build your app — and how to stop it
Left to guess, coding agents bolt on features no real product ships, then ship a toy where it counts. The pattern, the two failure modes, and the fix: frequency data from real products.

What a real school management system includes — the complete module checklist
A deep, opinionated spec of every module a school management system actually needs: the core that's non-negotiable, what each module must do (not just exist), the optional ERP layer to defer, and the cross-cutting things that decide whether a school keeps the software.
- School
How to build a school management system: the practitioner's guide (2026)
A deep, build-order guide to a school management system that survives a real school — the data model, the roles matrix, fees with installments, year-end promotion, migration, and the traps that turn AI-built systems into demos that die in production.
- School
What breaks when you build a school management system — the failures that show up every time
Every school runs on software everyone hates, so people build their own — and it falls apart in the same eight places. A deep look at the failures, why an AI agent walks into all of them, and what a system that survives a real school does instead.
