How to Stock a Walk-in Clinic: Supply Budget and Inventory Plan

15 août 2026

When a walk-in clinic in Surrey, BC, opened last January, the owner handed me a first-year budget built around one number: 1,000 patient visits a month. Not square footage, not headcount. Visits. In a fee-for-service clinic, every consumable you buy traces back to how many exam rooms you turn over per day.

This article shows how that clinic built its supply budget, how you can build the same model, and where the numbers usually break down.

Start with cost per visit

Budget from visits, not from last year's spreadsheet. Pull three months of purchase orders, divide each category total by visits, and average. New clinics can use the ranges below.

Category	Cost per visit
Gloves	$0.45 - $0.70
Masks and PPE	$0.15 - $0.25
Exam table paper	$0.05 - $0.10
Other disposables	$0.40 - $0.80
Sharps and waste	$0.20 - $0.35

The monthly budget formula

The math is plain: monthly budget = visits per month x cost per visit, summed across categories.

For the Surrey clinic at 1,000 visits: gloves at $0.55 = $550, masks at $0.20 = $200, exam paper at $0.07 = $70, other disposables at $0.60 = $600, waste at $0.25 = $250. That comes to roughly $1,670 a month, about $20,000 a year before HST. Two adjustments matter: flu season runs 20-30% above baseline from November to February, and new clinics overshoot the model by 10-15% in the first 90 days.

Inventory turns

Turnover rate = annual cost of goods used divided by average inventory value on hand.

A walk-in clinic should run 8-12 turns a year on high-volume disposables. Under 6 turns means too much cash in cardboard; over 15 means you are one shipping delay away from running out of gloves mid-shift. At $20,000 annual spend and 10 turns, you hold about $2,000 in stock and reorder every five weeks.

Safety stock and order cycles

Safety stock covers the gap between ordering and delivery. From McKesson or Medline warehouses in Western Canada, lead time is 2-5 business days; Cardinal Health runs similar. Buying direct from overseas stretches that to weeks, so safety stock has to grow. Rule of thumb: safety stock = average daily usage x (lead time in days + 3). At 1,000 visits a month you use about 40 boxes of 100-count gloves; at a 5-day lead time, hold 11 boxes as buffer.

Supplier agreements: negotiate volume, not price per box

McKesson, Medline, and Cardinal Health all quote tiered wholesale discounts. The real lever is order frequency. Consolidate weekly orders into monthly ones and commit to a quarterly volume to unlock 5-15% off list on many SKUs. Ask for net-30 terms and a written 90-day price lock - disposables have been inflationary since 2021. Keep one backup supplier on file even if you rarely use them; when a distributor back-orders a SKU, a standing account elsewhere is the difference between a quiet week and a scramble.

Expiry waste: the cost nobody budgets for

Most clinics find expired stock during the annual deep clean. Gauze, tape, and sterile dressings have shelf lives; nitrile gloves age too, especially stored warm. Three habits keep write-offs near zero: first-in-first-out rotation, labelling shelves with the delivery month, and capping slow movers at a 60-day supply no matter how good the volume discount looks. If write-offs exceed 2% of annual spend, your ordering cadence is the problem, not your staff.

A sample first-year plan

Back to the Surrey clinic at $20,000 a year:

Gloves: $6,600. Buy in case lots of 10; per-box pricing drops about 12% at that volume. Use CliniEco 4mil nitrile gloves.
Masks: $2,400. ASTM Level 1 covers most walk-in visits. CliniEco ASTM Level 1 procedure masks fit the exam room.
Exam table paper: $850. A 21-inch roll at 125 feet covers roughly 35-40 exams. CliniEco 21-inch exam table paper fits standard tables.
Other disposables and waste: $10,150.

That plan holds about $2,000 in average inventory, turns 10-11 times a year, and leaves a 5% contingency for flu season.

Health Canada checks at the purchasing desk

Medical gloves are Class I or II devices under the Food and Drugs Act and need a Health Canada licence number - an MDEL or device licence - on the box or in the importer's paperwork. Procedure masks for medical use are the same. If a distributor cannot produce it, walk away. For the CRA, hold supplier invoices for six years, and a clean inventory log makes HST input tax credit claims straightforward.

Start from visits, hold 8-12 turns, keep safety stock at lead time plus three days, and treat expiry waste as a metric. If these numbers feel off for your clinic, recalibrate after your first quarter.
