OAK & NINE
HomeBy industry/for-construction
For contractors, sub-contractors & modular builders

Nobody can tell you what the job has cost until it’s too late to act.

Tender to site to final account, run across drawings, variations and a dozen sub-contractors, with the real position living in one QS’s spreadsheet. Capture how your jobs actually get delivered, connected from estimate through to retention, and see the margin while you can still protect it.

Built around how your world works.

The connected picture across your functions is live today. Sector-specific benchmarks and templates are on the roadmap.

01
Tender to final account

One connected view from estimate through site to retention, so the job you priced and the job you built can finally be compared.

02
Variations that get paid for

Instructions, delays and extras captured as they happen, while the evidence is still to hand.

03
Cost to date, today

See what a job has cost without waiting on a valuation cycle. The delay is where the margin goes.

04
Sub-contractor dependencies

Know which trades, suppliers and approvals a programme actually hangs on, and which of them nobody has a second option for.

Across the seams

The job on paper and the job on site drift apart daily.

The estimate assumes a programme site can’t hold. Site takes instructions the commercial team never sees priced. The final account argues over what happened nine months ago. Oak & Nine connects what each part of the job knows into one base, so the commercial position moves at the same speed as the build.
