From a site requisition to a material issue — a closed chain
The most expensive leak in contracting is not the price. It is the material issued with nobody knowing to which project, and the subcontractor paid beyond what they executed. Here the chain is closed: requisition, approval, purchase order, receipt, issue — each step attached to a project item.
The questions it answers
Questions usually discovered after the money has left.
"Which project was that material issued to?"
An issue from stores must name a project, and the cost moves from stores to the project in the same movement.
"Who asked for this and who approved it?"
The request starts at site with its justification and passes an approval chain before the purchase order. No order without approval.
"How much did this subcontractor actually earn?"
A subcontract certificate on executed quantities, less retention, less the materials you supplied them — computed, not estimated.
"Stores is short — why?"
A stocktake compares physical to book, and an adjustment requires a reason and an approval. So a shortage becomes a written decision rather than a disappearance.
What is inside
Four modules that complete each other.
How it connects to the rest
No module works alone. These are the links that keep the numbers consistent.
Project costing
Purchases, issues and subcontract work are all cost lines on the project — they enter the margin immediately.
Finance
A supplier invoice posts with its account and tax; a payment voucher allocates it.
Stores & estimating
The item’s average cost from your actual purchases feeds item pricing in new quotations.
Approval
Every step involving money has an amount threshold and a matching approval chain.
Try it on one store
One store and its items, and a full cycle: requisition → purchase order → receipt → issue against a project.
