The Field Reality
Construction project profits are won or lost in the field. When your sites rely on paper sign-in sheets, unlogged WhatsApp messages, and disconnected store notebooks, margin slippage is inevitable.
Paper muster rolls are easily manipulated, prone to buddy clocking, and vulnerable to phantom casuals added to weekend pay sheets by corrupt site intermediaries.
Contractors routinely lose 10% to 18% of their weekly labor budget to fraudulent attendance claims.
Mid-week cash advances ("sub") given out on scrap paper get forgotten by Saturday payroll, leading to worker disputes, supervisor stress, and negative payouts.
Unreconciled cash advances wipe out supervisor accountability and cause painful weekend wage delays.
Cement, steel rebars, timber, and fuel arrive on site with paper delivery notes that get stained, misplaced, or unrecorded in physical store registers.
Unaudited store disbursements mean materials vanish without vouchers, driving up procurement costs.
Complete Field Suite
Every feature in Constructa was crafted specifically for real-world job sites where speed, mobile accessibility, and strict financial controls matter most.

Disburse worker wages via M-Pesa or bank transfer using print-ready PDF master rolls, and review real-time stock balances to prevent site work stoppages.
Enterprise-Grade Peace of Mind
Your project finances, wage rates, and material records are safeguarded with institutional security protocols.
