Contract work, priced, certified and costed in your till

For builders, civil contractors and plant hire businesses. Bills of quantities, certificates, plant and job costs live in the same till and the same books as your shop.

Bills of quantities

Price the job from your own rates

Build a bill or import one from Excel. Rates are built up from your price list of materials, labour and plant, so a change in the price of cement moves every rate that uses it.

A bill of quantities for a clinic: its bills, sections and amounts, carried to summary. Demo data.
Price list and rate build-ups

One price list behind every rate

  • Materials, labour and plant priced once
  • Measuring sheets, provisional sums and prime cost sums
  • Tenderers' bills compared line by line, with arithmetic errors found

Contracts and certificates

Certified, invoiced and in the books in one step

The bill is locked at contract prices. Each valuation becomes a payment certificate, invoiced on the till's own fiscal invoice, with retention held and released and withholding tax recorded both ways.

Valuations and certificates on a clinic contract: four interim payment certificates with gross valuations, retention and amounts certified. Demo data.

Variations

Variations priced from the bill's own rates and approved before they count.

Retention

Held on each certificate and released at practical completion and at the end of defects liability.

Withholding tax

Tax withheld from you, and tax you withhold from subcontractors without a valid tax clearance, both tracked.

Plant and equipment

Know where every machine is

Each item on a QR label. Dispatch notes and return notes, signed on the site phone, say where it is; hire is charged to the day, the week or the month, or by the hour meter.

The equipment register: excavator, roller, mixer and scaffolding, with where each item is and when it is due back. Demo data.
Job costs

The bill is the budget

Stock issued from your shop to a job at cost, site labour by grade, plant and subcontractors, all set against each bill, so you see the margin while there is still time to act.

Job costs on a clinic contract: budget, spent and committed against each bill, with warnings. Demo data.
Tender pack

Never miss a tender for a lapsed paper

CR14, CR6, tax clearance, NSSA and PRAZ registration with their expiry dates. Each tender is a checklist, saved as one folder when it is ready.

The tender pack: company documents with their expiry dates, and tenders as checklists. Demo data.
Reports

Every report agrees with the books

Contracting reports: the contracts schedule with work in progress, retention, withholding tax and site labour, each tied to its account. Demo data.

The site phone

With Decima Launcher on a site phone, the team records dispatch and return notes with photos and signatures, meter readings and the site register, and the till checks each one.
