Procurement for clinic groups: from requisition to 3-way match

Healthcare procurement for a clinic group works best as one chain: requisition, request for quotation (RFQ), purchase order (PO), goods received note (GRN), then a 3-way match of PO, GRN and supplier invoice before anyone pays. Each step has an owner and an approval. Run it in healthcare procurement software that shares a ledger with finance, and every dirham spent has a paper trail.

This guide walks through each step, the controls that matter, and how to set tolerances for the match. It is written for finance leads and operations managers in multi-branch clinics, day-surgery centres and pharmacy groups.

Why clinics need a procure-to-pay process

Single clinics often buy by phone and WhatsApp, and pay whatever invoice arrives. That works until it does not: a supplier bills for a full carton when half arrived, a price creeps up without anyone noticing, or two branches order the same item from two suppliers at two prices. A written process is not bureaucracy. It is how you know that what you paid for is what you ordered, and what you received.

The chain, step by step

1. Requisition

A requisition is an internal request: “Branch B needs 200 units of this item by next week.” It should name the item from the item master, the quantity, the store and the reason. Approval goes to whoever owns the budget. Templates for routine orders save time and reduce errors.

2. RFQ and supplier selection

For items without a contract price, ask more than one supplier. Compare price, lead time, minimum order and shelf life on delivery (a cheaper product with short expiry can cost more in waste). For repeat items, negotiate a contract or blanket order so branches order at the agreed price without a new RFQ every time.

3. Purchase order

The PO is your commitment: item, quantity, price, delivery location and terms. An approval matrix by value keeps small orders fast and large ones reviewed. Changes after approval should create an amendment with a history, not an edit.

4. Goods received note

When stock arrives, the store records what was actually received against the PO: quantities, lot numbers, expiry dates and any items rejected for damage or short expiry. For clinics, this is also where FEFO starts: lots recorded here are the lots issued later. Our clinic inventory and FEFO guide covers that side.

5. The 3-way match

Before paying, accounts payable compares three documents: what was ordered (PO), what arrived (GRN) and what the supplier billed (invoice). If quantities and prices agree within tolerance, the invoice is approved for payment. If they do not, it is held for review.

• Price variance: the invoice price differs from the PO price.
• Quantity variance: the invoiced quantity differs from what was received.
• Total variance: the invoice total differs from the expected total.

6. Debit notes and returns

When goods are short, damaged, rejected or overpriced, raise a debit note or a return to vendor. It reduces what you owe and leaves a record for supplier performance reviews.

Setting tolerances

Tolerances decide how much difference you accept before a person has to look. Too tight, and your team drowns in exceptions over rounding. Too loose, and real overcharges pass. Start tight, watch how often invoices fail, and relax only where the exceptions are genuinely trivial. Many teams keep tighter tolerances for high-value items and trusted-supplier tolerances for low-value consumables. Whatever you choose, write it down and review it quarterly.

Where procurement usually breaks in clinics

Most clinics do not lack a process on paper. They lose control at a few predictable points:

• Orders placed outside the system. A doctor or nurse calls a supplier directly for an urgent item, and the invoice arrives with no PO to match.
• Receiving without checking. The delivery is signed for at the door and counted later, or never. Short deliveries and short-dated stock go unnoticed.
• Free-text items. The same product exists under three names, so usage and price comparisons are meaningless.
• Invoices paid from email. Accounts payable pays what arrives because nobody can quickly see the PO and the GRN side by side.
• Credits never chased. A shortage is noticed, a phone call is made, and the credit never arrives because nothing was raised in writing.

Each of these has a simple rule as the fix: no PO, no payment; nothing is received without a GRN; every item comes from the item master; every shortage becomes a debit note. The rules only stick if the system makes the right way the easy way.

Central vs branch purchasing

Most groups settle on the hybrid: head office negotiates contracts and approves large orders, branches requisition and receive, and finance matches and pays centrally. See how that fits into the wider structure on our multi-branch groups page.

How Helix handles procurement

Helix runs the full chain: requisitions with approval, RFQs with evaluation and award, purchase orders with amendments and an approval matrix, blanket orders and supplier contracts, GRNs that capture lots and expiry and can reject goods on receipt, a side-by-side 3-way match with configurable price, quantity and total tolerances, debit notes and returns to vendor. When a GRN rejects goods, Helix drafts a debit note for review; nothing is posted until someone approves it.

Because procurement and clinic accounting share one ledger, a matched invoice lands in accounts payable without re-typing, with the cost center and branch already set. Supplier scorecards and price-drift checks help at contract renewal. For how branch costs roll up, read multi-branch clinic accounting.
