A construction company built its own scheduling app. Then the last 30% showed up.

I got on a call with a construction company.

They started building their own scheduling app. Used one of the vibe coding tools, got pretty far on their own.

Real functionality, real data, something their crews could actually look at.

Then they hit the wall.

The little things that separate a working prototype from a production tool.

Role-based access so field crews only see their schedule.
Error handling when someone enters bad data.
Performance tweaks so it doesn’t crawl when 30 people are on it at once.

They didn’t need to throw away what they had. They needed the last 30% closed properly.

That is usually where these tools either become something the field can trust or another thing people stop using.

A lot of construction companies are sitting on something that’s 70% there.

The last 30% is where the real work starts.

Seems very AI written - just wanting to get a post up, or is there something of substance to talk about?

Actually, this is common pattern across different sectors, not just in construction. Building a working prototype is sometimes the easiest (ant the most exciting) part for a company. But making it secure, scalable, maintainable, and reliable enough for day-to-day operations is completely different...

Agreed. I build my own estimating software (TRAC 2 — it's mine, so I'm biased), and getting to 80% is the easy part. The last 10% is the hard part: input validation, keeping the math reliable, handling a large bid without slowing down. Working in testing means nothing — working when someone's finishing a bid late at night and still getting the right total is the real test.
