Material Requisition in Construction: The Workaround Problem
Material requisition in construction is meant to be the first step in a controlled procurement process. In reality, it is often the step that site teams skip.
The logic is very simple from the site manager's perspective. A material is needed. The formal requisition process involves logging into a desktop system, filling out fields, waiting for office-based approval, and chasing confirmation. A phone call to the supplier takes three minutes. The material arrives the next day. The requisition is never raised.
This is a design problem more than a discipline. Research consistently shows that up to 40% of construction workers' time is non-productive; spent waiting for materials, approvals, or instructions. When the requisition process adds to that wait rather than reducing it, site teams find a faster path. And every time they do, the procurement and cost control framework loses visibility over what has been committed and why.
Let's go through what happens when material requisition in construction is too slow or too complex for site teams to use; and what purchase requisition software for construction does to fix it.
Why Site Teams Work Around the Requisition Process
The workaround is always rational from the site team's point of view. A foreman responsible for keeping a programme on track cannot afford to wait two days for approval on a material request that is needed tomorrow. If the formal process cannot move at the speed of the site, the site moves without it.
The most common workarounds in construction are:
- Verbal requests to the site manager or procurement team, followed by informal confirmation
- Direct supplier contact, bypassing the internal procurement system entirely
- Borrowing from another project without raising a transfer record or getting approval
- Using contingency or day-works to cover material costs rather than raising a proper requisition
- Retrospective requisitions raised after the fact to legitimise a purchase already made
Each workaround is individually minor. Cumulatively, they create a procurement record that does not reflect what has actually been committed. The project cost report becomes unreliable. Budget overruns are discovered late. Audits reveal gaps that nobody can explain. And the procurement team tasked with controlling costs, is managing a process that has been systematically bypassed by the people who need it most.
The retrospective problem
Retrospective requisitions are the most common workaround and the most damaging. When a material has already been ordered, delivered, and used before the requisition is raised, the approval process becomes a rubber stamp. The budget check happens after the commitment. The cost code is assigned by memory. The audit trail shows a timestamp that does not match reality. This is not a process failure on the site team's part, it is evidence that the material requisition process was not designed for how construction sites actually work.
What It Costs When Material Requisitions Are Not Raised
The immediate cost of a missed requisition is visible: a material is purchased without a budget check, a cost code is missing or wrong, and procurement loses the audit trail for that transaction. The downstream costs are less obvious but more significant.
Budget overruns that appear without warning
When material requests bypass the requisition process, committed costs are invisible to the procurement and finance teams until an invoice arrives. On a large project with multiple site teams, the cumulative effect of informal purchases can represent a material budget overrun that only surface at month-end, which is too late to take corrective action.
Duplicate procurement and over-ordering
Without a central requisition record, different site teams or project managers may order the same materials independently. Over-ordering consumes budget, creates excess stock that is difficult to account for, and often results in materials being transferred between projects informally, compounding the visibility problem.
Inter-project transfers that distort cost records
When materials are borrowed from one project to cover a shortage on another, a common consequence of missed requisitions; the cost typically stays with the originating project unless a formal transfer record is raised. In practice, informal transfers are rarely documented. The originating project absorbs a cost that belongs elsewhere, and the receiving project shows a lower cost position than it should. Both project accounts become unreliable.

Supplier relationships outside the approved supply chain
Direct procurement by site teams often involves suppliers that have not been through pre-qualification, are not on approved supplier lists, and do not carry the required insurance or compliance documentation. Each informal purchase creates a compliance gap; and in the event of an incident or dispute, those gaps carry real legal and financial exposure.
The cost of waiting
A study on construction inventory management found that a 10 to 12% reduction in labour cost can be achieved simply by eliminating non-productive idle time caused by searching for materials or waiting for new arrivals. When the material requisition process is the bottleneck that delays material availability, it is not just an administrative problem, it is a direct driver of the labour cost overruns that erode project margins.
What the Material Requisition Lifecycle Should Look Like
Understanding where the process breaks down requires clarity on what it should look like when it works. A material requisition in construction moves through four distinct stages:
Stage 1 - Request
A site team member identifies a material need and raises a requisition; specifying the item, quantity, required delivery date, cost code, and project. In a well-designed system, this takes under two minutes and can be completed from a mobile app on site.
Stage 2 - Approval
The requisition is routed automatically to the appropriate approver based on value threshold, project, or material category. The approver reviews, approves or queries, and the system notifies the requester. A live approval ageing view ensures that pending requisitions do not go unnoticed.
Stage 3 - Procurement
An approved requisition triggers the procurement workflow: a request for quotation if a supplier is not already selected, or a purchase order raised directly against an approved supplier and linked to the project budget. The requisition and PO are linked; creating a traceable record from request to order. For more on how this fits into the end-to-end procurement workflow in construction, see our dedicated guide.
Stage 4 - Receipt and Closure
When materials arrive on site, the delivery is checked against the original requisition and purchase order, a Goods Receipt Note is raised, and the requisition is closed. Closure confirms that the need has been met, the cost has been posted, and the commitment is settled. A closed requisition is a complete record.
When all four stages run in sequence, the procurement team has a live view of what has been requested, what is approved, what is on order, and what has been received. The finance team has an accurate committed cost record. And the site team gets materials without bypassing the system, because the system moves at the speed they need.
Material Requisition Form for Construction: What It Should Contain
Whether your team uses a paper form, a spreadsheet, or a digital workflow, every material requisition in construction should capture the same core information. The fields below represent the minimum required for a requisition to be actionable; meaning it can be approved, procured, received and cost-posted without anyone chasing missing details.
Why paper forms and spreadsheets fall short
A paper or spreadsheet-based material requisition form captures the fields above, but it cannot route the form for approval, check available stock, trigger a purchase order, or update the cost record automatically. Each of those steps requires a manual handoff. And manual handoffs are where construction requisition processes break down: fields are left blank, forms are lost, approvals sit in email inboxes, and by the time the procurement team acts, the site team has already called the supplier directly.
In Xpedeon, the material requisition form is a structured digital workflow; the same fields, raised from a mobile device on site, with automatic approval routing, live inventory checking, and direct connection to the purchase order and cost record. The form does not change. What changes is everything that happens to it after it is submitted.
How Xpedeon Solves Material Requisition for Construction Site Teams
Most requisition processes in construction were designed for office environments and not for site teams working from vans, scaffolding, or temporary site cabins with intermittent connectivity. Purchase requisition software for construction must meet the site team where they actually are. Xpedeon’s mobile-first approach is built around how construction sites actually operate: fast, role-appropriate, and connected to the procurement and cost control framework from the moment a request is raised.
Mobile Requisition from Site: Where the Process Breaks Without It
The most common reason site teams bypass the formal requisition process is that it cannot be done from the site. The most important single capability in purchase requisition software for construction is the ability to raise a requisition from a mobile app; with the same project linkage, cost code assignment, and approval routing as a desktop submission. If the mobile experience is a simplified version of a desktop form, site teams will still work around it. Xpedeon’s mobile app is a genuinely fast, role-appropriate interface; and data syncs in real time with the core Xpedeon system, so procurement sees the request the moment it is raised, not when someone gets back to the office.

Role-Based Access: Site Teams See What They Need
A site foreman does not need to see the full procurement workbench. In Xpedeon, each user sees only the modules and views relevant to their role. A site team member can raise a requisition, track its approval status, and confirm when it is on order, without navigating a system built for the commercial team. This role-based design removes the friction that drives workarounds without removing the control that procurement needs.
Approval Workflows That Move at Site Speed
If a material requisition requires three approval levels with a 24-hour window at each stage, the process is slower than a supplier phone call. Xpedeon’s approval workflows are configurable by value threshold, project type, and material category; so routine, low-value requests can be approved with a single sign-off, while larger commitments follow the full matrix. Approval ageing reports give procurement teams live visibility into any requests sitting idle before they become a workaround.
Inventory Integration: Check Stock Before Raising a PO
Before a requisition triggers a purchase order, Xpedeon checks live inventory levels across the project and connected warehouses. If the required material is already in stock or available from another site, the system surfaces this automatically, reducing duplicate orders and enabling a controlled internal transfer rather than a new external purchase through live construction inventory management data. This is what prevents the duplicate ordering and informal borrowing that emerge when requisition and inventory systems are separate.
Issue and Transfer Requisitions with Full Traceability
For materials already held in stock, site teams can raise issue and transfer requisitions through the mobile app; linked to activity, asset, or cost code with the same approval and documentation discipline as a purchase requisition. Every material movement is recorded, posted to the correct project account, and traceable. No informal transfers. No cost miscoding. No audit gaps.

Full Lifecycle Visibility from Request to Closure
Procurement teams using Xpedeon’s construction procurement software have a live view of every requisition across all projects: raised, pending approval, approved, on order, and received. Every material requisition in construction generates a traceable record: who raised it, when, what was requested, who approved it, what was ordered, when it arrived, and how the cost was posted. This audit trail is the foundation of accurate cost reporting, budget control, and compliance documentation; from the original request through to GRN completion and cost posting.

From Workaround to Workflow: What Changes When the System Works
When site teams work around the material requisition process in construction, they are not being undisciplined. They are responding rationally to a process that was not designed for how construction sites work. The workaround is a signal that the process has a friction problem; and friction problems in procurement do not stay contained. They spread into the cost record, the budget, the audit trail, and eventually the project margin.
The evidence for what happens when that friction is removed is increasingly clear. What changes when the system works is not the behaviour of site teams; it is the conditions they are working in. Xpedeon customers across regions describe the same shift: from chasing approvals and working around the system, to a procurement process that moves at the speed of the site.
Lovell Homes reduced manual procurement effort by 85% and cut their payment cycle from four days to one and a half days; the kind of visibility gain that makes the formal requisition process faster than the workaround. DMU, a real estate developer, achieved 40% faster approvals, directly eliminating the bottleneck that most commonly drives site teams to call suppliers rather than raise a requisition.

Purchase requisition software for construction that meets site teams on their mobile devices with fast approval workflows, live inventory visibility, and full traceability; removes the incentive to work around the system. When the formal process is faster and easier than the informal one, site teams use it. And when site teams use it, procurement has the visibility it needs to protect both schedule and margin.
Every informal material request that bypasses the requisition process is a commitment your procurement team cannot see and a cost your finance team cannot account for.
