Control contractor margin from estimate to final payment.
Estimation, BOQs, labour, project P&L, IPCs, retention, advance recovery, PDCs, and billing — connected in one contractor-focused ERP built around margin control.
Marina Tower — Interior Fit-Out
Stop pricing from memory. Stop running projects from Excel.
Most contractors lose margin not on site, but in the gaps — between the estimate, the contract, the certificate, and the collection.
Pricing from memory and old spreadsheets
Priced from a live rate library, per project
Project profit only known at the end
Project P&L tracked against the bid, live
IPCs, retention and advance in side files
Certified in one place, deductions built in
PDCs and collections a monthly surprise
Cheque maturity and cashflow visible ahead
Every stage of the job, under one roof
From the first estimate to the final retention release — connected, not stitched together.
Estimation & BOQs
Build estimates from a live schedule of rates. Import BOQs, flag rate gaps, and carry margin through to the tender.
Project P&L
Track committed cost, actual cost, and certified value against the bid — so margin erosion shows up early, not at handover.
Labour & attendance
Site attendance and crew productivity connected to project cost and progress, not stranded on paper.
IPCs & progress billing
Certify interim payments with retention, advance recovery, and previous certificates handled automatically.
Contracts & variations
Awarded contracts, variation orders, and their commercial impact tracked against the original scope.
Procurement & inventory
RFQs, supplier prices, purchase orders, and site material consumption tied back to the project budget.
Priced BOQs in, certified payments out
The same structured data flows from the bill of quantities through to the interim payment certificate.

What contractors ask
Specific answers for estimating, commercial, and finance teams.
Yes. Estimates are built from your rate library and BOQ codes. You control the structure; Zenith keeps it priced, versioned, and connected to the project.
Retention percentages, advance recovery, and previously certified amounts are applied automatically when you certify an interim payment — no side spreadsheet.
Project P&L compares committed and actual cost against the bid in real time, so a slipping package is visible while you can still act on it.
Customer and supplier post-dated cheques are tracked through their full lifecycle with maturity alerts, feeding directly into project cashflow visibility.
