Is Switching to a 3PL Actually Cheaper? How Canadian E-Commerce Owners Can Do the Math
To know if a 3PL is truly cheaper, you need to calculate your all-in cost-per-order today — including labour, warehouse space, packaging, and your own time — then map every 3PL fee (receiving, storage, pick-and-pack, shipping, returns) against that number. Most owners discover their current cost is higher than they thought, or that the 3PL's hidden fees close the gap fast.
Build Your Baseline First — What Does Fulfillment Actually Cost You Right Now?
Before you can compare anything, you need one number: your true cost-per-order today. Most owners underestimate it because the costs are scattered.
Add up everything that touches fulfillment over a typical month:
- Labour — wages (or your own hours × a realistic hourly rate) spent picking, packing, and shipping
- Warehouse or storage space — your rent or a fair allocation of it if you're using your own premises
- Packaging materials — boxes, tape, void fill, mailers, inserts
- Shipping costs — what you actually pay carriers, minus any discounts
- Returns processing — time and materials to inspect, restock, or discard
- Overhead — insurance, equipment, any software you use only for fulfillment
Divide the total by your monthly order volume. That's your current cost-per-order. Write it down. It often surprises people.
Now Decode the 3PL's Pricing
3PL quotes look confusing because they're modular — you're essentially seeing a restaurant menu, not a set meal price. Here are the line items to request and understand:
| Fee Type | What It Is |
|---|---|
| Receiving fee | Charged when your inventory arrives at their warehouse (per pallet, per unit, or per hour) |
| Storage fee | Monthly charge per bin, shelf, or pallet position — this scales with your SKU count and velocity |
| Pick-and-pack fee | Per-order charge, sometimes with a per-item add-on after the first unit |
| Packaging materials | Some 3PLs include standard boxes; custom packaging is almost always extra |
| Shipping | Usually passed through at their negotiated carrier rate — this is often where 3PLs win on cost |
| Returns/reverse logistics | Per-return fee to receive, inspect, and restock |
| Account minimums | Some 3PLs charge a minimum monthly fee regardless of volume |
Ask for a sample invoice based on your actual order profile — SKU count, average units per order, monthly volume, average package weight. Any reputable 3PL will run this for you.
Do the Apples-to-Apples Comparison
Once you have the 3PL's estimated monthly cost, calculate their cost-per-order and put the two numbers side by side. Then adjust for a few things most owners miss:
What gets cheaper: 3PLs often have significantly better shipping rates than a small business can negotiate alone — sometimes 30–50% less on common courier lanes. That alone can flip the math.
What gets more expensive: If your SKU count is high but your order volume is low, storage fees accumulate fast. A 3PL is generally more cost-effective when you have high volume and a tight SKU range.
What you're not counting: Your time. If you're personally packing boxes at 10 p.m., that time has a real value — it's just not showing up on any invoice. A 3PL can hand that capacity back to you.
The Number That Actually Matters
The goal isn't to find the cheapest fulfillment option in isolation — it's to find the option that costs the least per dollar of revenue you can generate. If a 3PL frees you to focus on customer acquisition or expanding to a new sales channel (say, adding Amazon to your Shopify store), the ROI calculation changes entirely.
This is the kind of multi-variable cost analysis — across platforms, across cost centres — where having a clear financial picture of your business pays for itself. Knowing your true margin per order, per channel, before you sign a 3PL contract is how you negotiate from a position of strength, not guesswork.
Frequently asked questions
What is a typical pick-and-pack fee at a Canadian 3PL?
Pick-and-pack fees at Canadian 3PLs typically range from $2.50 to $5.00 per order for a single-item shipment, with an additional $0.50–$1.50 per extra item. Rates vary by provider, volume, and whether you supply your own packaging.
At what order volume does a 3PL usually start making financial sense?
As a rough benchmark, many 3PLs become cost-competitive for Canadian e-commerce businesses shipping 200–500+ orders per month, especially if you're currently paying retail shipping rates. Below that threshold, the monthly minimums and storage fees can outweigh the shipping savings.
Will a 3PL's shipping rates actually be cheaper than what I'm paying now?
Often, yes — 3PLs consolidate volume across many clients and negotiate deeply discounted rates with carriers like Canada Post, Purolator, UPS, and FedEx. If you're shipping under your own account without a negotiated rate, the 3PL's rates can be meaningfully lower, sometimes enough to offset the pick-and-pack fees entirely.
How do I handle GST/HST on 3PL fees?
3PL services provided in Canada are generally subject to GST/HST, which means you'll pay tax on their invoices. As a GST/HST-registered business, you can typically claim those amounts back as an Input Tax Credit (ITC). Make sure your 3PL's invoices clearly show their GST/HST number — this is required for you to claim the ITC.
What questions should I ask a 3PL before signing a contract?
Ask for: a sample invoice based on your actual order profile, a full list of fees including minimums and surcharges, how storage is calculated (per bin vs. per pallet), their process and fees for returns, any setup or onboarding fees, and what happens if you want to exit the contract early. Getting a detailed quote in writing before you commit is non-negotiable.
Every business's cost structure is different — run these numbers against your own order profile, and talk to your accountant before making a major fulfillment decision.
