What is construction project management software?
Construction project software tracks budgets, bills of quantities, site material, subcontractor work and running-account bills in one system so project cost is visible against budget. Stack18 builds it for contractors and developers with site mobile apps and approval workflows.

Construction Project Software questions.
Can site staff use it without good internet?
We design the site app to capture data offline and sync later. We confirm the offline scope for your sites in discovery.
Do you support RA bills and retention?
Yes. Running-account bills are built from certified measurements, with retention, TDS and other deductions configured per contract.
Can we link it to Tally?
Yes. We can post vouchers to Tally so accounts keep their existing flow.
Is it for contractors or developers?
Both. Contractors focus on measurement and billing, developers on budgets, vendors and sales. We tailor scope in discovery.
How do we start?
With a two-week Discovery Sprint on one live project, then roll out to other sites in phases.
