  • Project Requisitions and Inventory Allocation: Avoiding Duplicate Purchasing

    A project requisition should not automatically become a purchase order. The first question is whether the required material already exists in stock or has already been allocated to the project.

    Demand starts with the requirement

    The requisition records what the project needs, when it is needed and for which activity or cost code. That demand can come from an estimate, bill of quantities, work package or field request.

    Check availability before procurement

    An integrated system can compare the requirement against available stock, reserved stock and material already committed on open purchase orders. Items on hand can be allocated; only the shortage should move to procurement.

    Allocation is not the same as physical issue

    Allocation reserves material for a project without necessarily moving it. Issue or consumption occurs later when the item physically leaves stores or is installed.

    Why this matters

    Without allocation logic, different projects may believe the same stock is available or buyers may order items that already exist. Linking requisitions, inventory and purchasing reduces duplicate procurement and improves cash control.

  • GRN and Partial Receipts Explained: Connecting Procurement to Inventory and Invoices

    A Goods Received Note (GRN) records what was actually received against a purchase order. It is a key control point between procurement, inventory, project delivery and supplier invoicing.

    Why partial receipts matter

    Suppliers often deliver purchase orders in stages. A useful GRN process therefore records line-level quantities received, accepted, rejected and still outstanding rather than simply marking the whole PO as complete.

    Stock items vs project items

    Stock items may increase warehouse inventory, while project-specific items can be received directly against a project or designated storage location. The accounting and ownership logic should remain traceable.

    Three-way matching

    Many organizations compare the purchase order, goods receipt and supplier invoice before payment. The PO shows what was ordered, the GRN shows what arrived, and the invoice shows what is being billed.

    Data quality

    Item code, unit of measure, quantity, project, supplier and PO reference should remain consistent through the process. Good master data reduces manual corrections later.

  • PR → RFQ → PO → GRN → Invoice: The Procurement Workflow Explained

    Digital Engineering Guide

    A controlled procurement workflow separates the request for something from the commercial commitment, physical receipt and financial liability. Understanding each stage makes automation and approvals far easier to design.

    PR — Purchase Requisition

    The requisition records the internal need. It should identify project or cost center, item, quantity, required date, specification and requester. Approval confirms that the organization authorizes procurement to proceed—not that a supplier has already been selected.

    RFQ — Request for Quotation

    The RFQ communicates the requirement to potential suppliers. Commercial comparison can evaluate price, lead time, payment terms, compliance, warranty and other criteria.

    PO — Purchase Order

    The purchase order is the formal commercial commitment to the selected supplier. It should preserve approved quantities, prices, taxes, delivery terms and project/cost allocation.

    GRN — Goods Receipt Note

    The GRN confirms physical receipt. Partial deliveries should be recorded against the PO without falsely closing the balance. Inspection or quality status may be separate from simple receipt.

    Supplier invoice

    The invoice creates the payable subject to validation. A three-way match can compare PO, GRN and invoice to identify quantity or price differences before payment.

    Why the workflow matters for project control

    The PR shows demand, the PO shows committed cost, the GRN shows received value and the invoice/expense supports actual cost. Linking those stages to the project gives management a much clearer picture of budget exposure.

    Frequently asked questions

    Can a requisition become a PO automatically?

    It can be automated after required approvals and supplier/commercial rules are satisfied, but control design should prevent unauthorized commitments.

    What happens with partial delivery?

    The GRN should record only the received quantity and leave the remaining PO balance open.

    Why is three-way matching useful?

    It helps prevent payment for quantities not ordered or not received and highlights pricing differences.

    Practical example

    Project-oriented systems such as PSEMIC ERP can link requisition, purchasing, receiving and project-cost reporting in one workflow.
