Construction software for builders and contractors

Yes. Estimark computes a live cost position for every job from three feeds: the cost ledger, timesheets, and purchase orders as they are received.

• Cost is split across six categories — labour, materials, plant, subcontractor, preliminaries and other.
• Labour actuals come from timesheet hours multiplied by the rate held on those hours.
• Materials come in as purchase orders are receipted, pro-rated by the quantity actually received.
• Committed cost is the VAT-exclusive value of issued orders not yet received, so it is never double counted against the receipted figure.
• Budget is your active budget baseline if you have set one, or the job’s estimate line items if you have not — and the position tells you which of the two it used.

NoteTimesheets and purchase-order receipts feed cost automatically. Everything else is a cost ledger entry you post yourself.

Yes — a genuine cost value reconciliation, per job and as a whole-portfolio pack, exportable to CSV.

• Every row carries contract value, approved variations, revised contract value, value certified, actual cost, committed cost, cost to complete and forecast final cost.
• Margin to date is value certified minus actual cost. Forecast margin is revised contract value minus forecast final cost.
• Revised contract value includes approved variations, so the CVR is never silently run against the original order value.
• A separate WIP report shows certified value against invoiced value, with retention held.

Yes. Estimark computes the statutory dates from the application date and refuses a pay less notice served too late.

• Due date defaults to 30 days after the application date.
• The payment notice deadline is 5 days after the due date, under section 110A.
• The final date for payment defaults to 14 days after the due date.
• A pay less notice must be served at least 5 days before the final date for payment. Serve it later and Estimark rejects it, quoting the deadline and stating that the notified sum remains payable in full.
• Retention defaults to 5%, is taken off the gross cumulative valuation, and a release at practical completion or defects-period end raises its own invoice.

NoteThese are the standard JCT-style defaults. They are not yet configurable per contract.

Estimark deducts on labour only — excluding materials, VAT and plant hire — uses the 6th-to-5th tax month, and records the CIS300 with both statutory declarations. It does not file to HMRC for you.

• Rates are 0% for gross payment status, 20% for a verified and registered subcontractor and 30% for unverified or unmatched.
• Verification is a real call to HMRC when you have supplied HMRC credentials. With no connection it refuses rather than inventing a verification number.
• The monthly return is due by the 19th of the month the tax period ends in, and Estimark flags it overdue past that date.

Yes. Site clock-on can be gated on three checks — site induction, an in-date CSCS card and acceptance of the current RAMS version — each set independently to off, warn or block for that job.

• A blocked clock-on is refused outright and names the check that failed. Warn lets the operative on and records the warning.
• All three gates ship off by default; you switch them on per job.
• The QR scan is geofenced, 100 metres by default and configurable from 10 to 5,000 metres.
• A live muster roll lists everyone currently clocked in — the list a fire marshal reads at the assembly point.
