Cloud-based Cost Management Software for Construction
Commercial control. In real time.
Chalkstring’s Cost Management module gives you a live, 360° view of every project’s commercial position — from procurement to final account.
Track cost, revenue, margin and cost-to-complete in one connected system. No spreadsheets, no surprises — just total control from day one.
Built for specialist contractors.
Chalkstring was built by people who know what it's like to run specialist contracting businesses. Every feature reflects the real challenges you face — from pricing work to tracking profit.
Whether you're in interiors, facades or beyond - or in a small or large business - we’ve designed a cost management system with the specialist trades in mind.
All the features you need
Post Tender Review
Reality-check the scope, pricing and assumptions before delivery begins — and lock in margin with a clean, structured commercial baseline.
Plant management
Track hired plant day-by-day, avoid hidden charges, and see real-time costs reflected in your live project performance.
Labour
Approve hours against live scope and mark up drawings with what’s been done and issue certification— progress, cost and performance all stay aligned.
Cost reports
See a live picture of your cost, revenue and margin position for all projects— with breakdowns by zone, package or cost type. No spreadsheets. No guesswork.
Procurement
Raise and manage material orders directly from your live scope. Log deliveries & reconcile invoices easily.
Variations
Track and price changes as they happen, not after the fact. Maintain a clear audit trail and protect your margin from scope creep.
Valuations
Log site progress accurately and build structured applications for payment — using live scope, variations and cost data. Nothing gets missed, nothing slips through.
Accounts integration
Integrates directly with Sage 50 and Xero, sending cost, invoice and payment data, with batch export options for other systems

Before Chalkstring

✕ Variations are buried in emails or tracked in separate files
✕ Valuations are slow, inconsistent and error-prone

✕ Forecasting cost-to-complete is manual guesswork
✕ Everyone’s working in different spreadsheets and systems
