How this record moves
The anti-leakage inventory control chain
From supplier weigh ticket to completed structure
- Starts with
- Receipt and weigh ticket scan
- Leads to
- Real-time over-consumption alert
In West African construction, material waste and theft represent 4% to 8% of total site cost. GestraPro locks canonical units, controls every delivery ticket, and secures inter-site transfers.
How this record moves
From supplier weigh ticket to completed structure

Strict canonical units
No arbitrary conversions
Scanned weigh tickets
Double-check receipt verification
Per-site isolated depots
Tracked inter-site transfers
Anti-leakage 4% to 8%
Theoretical vs actual matching
Cement disappearing faster than concrete advances, rebar diverted, sand billed but never delivered. Industry research attributes 4% to 8% of construction cost overruns to material losses. GestraPro transforms stock management into an unbroken chain of custody.
A core catalog of reference materials maintained by the platform with strict canonical units (50kg bag, m³, ton, liter, piece, bundle). Unit integrity is enforced at the schema level: no arbitrary conversions allowed. Each enterprise extends this catalog with private items.
Chain of trust
The event is logged with its site, timestamp, and operational context.
Geotagged photos, weigh tickets, and signed manifests remain immutably attached.
Project manager or leadership reviews variances and steers margin.
Project manager or leadership reviews variances and steers margin.
Upon every delivery of cement, sand, or aggregates on site, the storekeeper records the supplier weigh ticket, photos the signed delivery receipt, and confirms actual weight. Short deliveries are caught and contested before payment.
Each construction site maintains its own dedicated depot and local ledger. When trucks transfer rebar or cement from Site A to Site B, the movement requires origin dispatch validation and destination receipt sign-off: no materials vanish in transit.
The reconciliation engine compares quantities of cement and steel logged in the daily log against the theoretical volume of completed work (m³ of poured concrete, m² of blockwork). Any abnormal variance triggers an instant alert to the project engineer.
Periodic physical stock counts reconcile theoretical and actual stock with full audit trails. The supply price is frozen upon depot receipt for each batch, guaranteeing exact job cost calculations across geographic regions (Ouaga, Bobo, Abidjan).
100% offline-first operation with local sealed SQLite database, mobile-data frugal differential sync, native FCFA currencies, regional Mobile Money integrations, and SYSCOHADA (OHADA AUDCIF) cost accounting.
Materials track raw physical inputs; heavy equipment and fuel tracking secures the second major operational cost center.
The pilot is designed to produce useful evidence with your team, not to walk through an abstract demonstration.
