A plant room takes eleven weeks, four trades and a commissioning certificate. Your business runs on a spreadsheet, three apps and an engineer's memory. 8nterp puts the whole job — survey to service contract — on one spine.
Watch a commercial system go in. At every stage the steel behaves exactly as designed — and a piece of information falls on the floor. That information is your margin.
An engineer walks the building, measures the loads, and prices the job. Heat gain, duct routes, plant space, access. The quote goes out at six days of labour and a fixed equipment schedule.
The quote lives in a document. Nothing connects it to the hours worked against it — so an overrun is invisible until the job is closed and the money is already spent.
Condensers land on the roof, the air handling unit is craned in onto anti-vibration mounts. Filters, preheat coil, cooling coil, reheat coil, fan. Serial numbers, refrigerant charge, warranty terms.
Serial numbers go on a photo in someone's phone. Warranty registration is a task nobody owns, and the F-gas charge log is a spreadsheet the auditor will eventually ask for.
Supply runs the riser and out along each floor; return comes back to the plant. Hung, sealed, pressure-tested. This is where the eleven weeks go: four trades sequencing around each other in one ceiling void.
Hours are written on paper and typed up on Friday, badly. Van stock walks. The variation the client asked for on Tuesday is agreed verbally and never priced.
Cassettes and diffusers go into the ceiling grid, drains fall correctly, condensate is proved. The part the client will actually look at every day for fifteen years.
Snags are captured on WhatsApp. Which of forty terminals was replaced under warranty in month three is a question no system can answer.
Airflows balanced, temperatures proved, controls strategy demonstrated, certificate issued, O&M manual handed over. The job is done — and the most valuable part of it has not started.
The service contract. The recurring revenue that makes this business worth owning is tracked in a calendar reminder, and it quietly lapses.
Nobody buys a platform because the tabs are nicer. Move the two sliders and see what the gaps cost you in a year. The assumptions are printed underneath — change them in the meeting if you disagree.

Assumptions: 1,500 billable hours per engineer per year; 4% of worked hours never reach an invoice; 3% of project value lost to un-priced variation and undetected overrun; 8% of the service base lapses at renewal; €900 of van stock per engineer written off. Conservative against published field-service benchmarks, and every one is arguable — bring your own.
A twelve-engineer contractor is leaking €0 a year.
Most contractors bolt a customer portal onto the side and reconcile it nightly. There is nothing to reconcile here. The client's project view and your job record are the same row, filtered — so the moment you move a job to Commissioning, their screen says Commissioning.

Not a discount bundle. The nine of 8nterp's sixteen modules that a climate contractor actually runs on, pre-configured to the way the work already happens — sharing one customer, one product list, one ledger.
Stage 01
The survey, the load calculation and the quote become the same object the job is later measured against.
Stage 01–05
Programme, trades, dependencies. The eleven weeks, visible while they are happening.
Stage 02
Serial numbers, refrigerant charge and every part booked to the job it went into.
Stage 02
Crane slots, deliveries and engineer routing, against the programme rather than beside it.
Stage 03
Hours captured on the phone at the job. Timesheet, payroll and invoice are the same number.
Stage 03
Variation priced when it is agreed. Cost and revenue on the job while it can still be steered.
Stage 04
Certificates, O&M manuals, F-gas logs and warranties, filed to the asset and findable in a year.
Stage 05
Every commissioned system becomes a renewal with a date and an owner — never a calendar reminder.
All stages
Margin per job, per engineer, per client. Which work to stop taking, in a number.
Every path lands on an annual agreement plus a one-time implementation. Land on the modules that hurt most; expand when the first ones have paid for themselves.
Option A
Take one. Most contractors start where the bleeding is worst.
Option B · recommended
The nine modules above, pre-configured to the five stages, implemented against your live jobs.
Option C
Three, six, nine, twelve or all sixteen, with volume pricing.
So do not run one either. We survey your business the way your engineers survey a building: measure what is actually happening, price the gap, and show you the number before you commit to anything.
Ninety minutes, on your own jobs and your own figures. You leave with the leak quantified whether or not you ever buy a licence.
