Construction Management SoftwareDevelopment
Compare budget with actual cost per project and per cost code while the work is still underway, not after the last payment.
Construction Management Software Development: what the work involves
Construction margins are made or lost on site, in the small decisions: material ordered twice, a subcontractor paid for work not yet measured, a variation agreed on the phone and never billed. Contractors who keep cost records in several notebooks and a Excel BOQ learn the real project cost only when it is finished. By then a loss-making job has already consumed the cash the next one needed.
DevKey builds construction systems around the project, its bill of quantities and cost codes. Budgets are set per code; purchase requests from site become approved orders; material receipts are recorded at the project store; subcontractor measurements generate certified bills with retention; and variations are logged as change orders. Site engineers enter progress and material use from a phone, while head office sees committed cost, paid cost and forecast against budget for every project.
Core features
BOQ and project budgets
Import or build a bill of quantities, assign cost codes, and track budget against committed and actual cost per item.
Site purchase requests
Engineers raise requests from site, head office approves and converts them to purchase orders, and receipts close the loop.
Project store and material use
Stock at each site store, issues to work areas, returns and wastage, so consumption can be compared with the BOQ norm.
Subcontractor measurement and bills
Measured work, rate, retention and advance recovery produce a certified bill that cannot exceed approved work orders.
Variations and change orders
Extra work and client-requested changes are logged with approval status and priced, so they reach the invoice instead of being absorbed.
Progress and cash-flow reports
Physical progress against plan, cost to complete, client billing status and payables due, per project and in total.
What we get right before launch
Site connectivity and discipline
Sites have poor signal and busy engineers. Mobile screens must be short, work offline for entries, and sync later, otherwise data stays in notebooks and the system stays empty.
Measurement disputes
Bills turn on measured quantities. Measurement sheets, dates and approver names are stored with each certificate so a disagreement can be traced to the agreed figure.
Retention and advances
Retention held and mobilisation advances recovered are easy to mishandle. We track them as running balances per subcontractor with a clear statement on each payment certificate.

Common questions, answered
Can we import our existing BOQ from Excel?
Usually yes. We map your BOQ columns to item, unit, quantity and rate, assign cost codes, and load it into the project budget. Irregular sheets need some cleaning first, which we do together with your quantity surveyor.
Can site staff use it on phones with weak signal?
Site screens are designed for phones, and we can queue entries offline and sync when a signal appears. That keeps daily material and progress entries flowing even from basements and remote locations.
Does it control subcontractor payments?
Bills are checked against work orders, measured quantities and rates, and payments need the approvals you define. The system shows retention, advances and what remains payable, so over-payment is caught before cash leaves.
Can it work alongside our accounting software?
Yes. Approved bills and payments can post to your accounting system by export or API, and cost codes map to ledger accounts. We agree the mapping with your accountant so project cost and books reconcile.
