Amazon FBA can remove some of the work of fulfilling orders. It does not remove the need to choose a viable product, manage inventory and understand the margin. The useful question is whether the service fits your product and operating model.
Evaluate FBA at product level before committing a large quantity of stock. A business can increase sales and still earn less if fees, returns and advertising absorb the contribution.
What Amazon handles through FBA
Under the programme, sellers send eligible inventory to Amazon, which provides fulfilment services including storage, picking, packing and shipping, with customer service and returns under its terms. Review the current Amazon Canada FBA description for details.
You still need to handle the seller’s wider responsibilities, including product selection, sourcing, funding and applicable requirements. An agency may support defined marketplace work; it is separate from Amazon’s fulfilment operation.
Build a cost model for the actual item
- Product acquisition or manufacturing cost.
- Preparation, packaging and inbound transport.
- Selling-plan and referral fees as applicable.
- Fulfilment, storage and potential additional inventory charges.
- Advertising, agency support and other operating costs.
- Returns, damage, removals or other relevant allowances.
Amazon’s Canadian pricing page explains the fee categories. Rates depend on the product and programme details and can change, so use the current Revenue Calculator with accurate dimensions, weight and category instead of copying a generic fee into your plan.

A hypothetical CAD example
| Illustrative item | Per unit |
|---|---|
| Sale revenue before applicable tax | $40 |
| Product cost | −$12 |
| Allocated selling, fulfilment and storage costs | −$11 |
| Preparation and inbound transport | −$3 |
| Advertising allowance | −$6 |
| Returns and other variable-cost allowance | −$2 |
| Illustrative contribution | $6 |
These are invented planning inputs, not Amazon’s quoted fees or a forecast. They exclude fixed overhead and any unlisted costs. A small change in advertising expense or returns would materially affect the result. Get appropriate tax advice for your situation rather than treating this example as a tax calculation.
Compare fulfilment options honestly
Compare FBA with fulfilling orders yourself or using another provider. Include your labour, service expectations, delivery coverage and inventory visibility. Bulky, slow-moving or low-margin items may need a different approach from compact items with predictable demand.
Model a slower sales case as well as the expected case. Stock held longer than planned ties up cash and can create additional costs. Do not use a sales forecast as a guarantee of sell-through.
Start with a controlled operating test
Verify product eligibility, listing accuracy, preparation and replenishment responsibilities before sending inventory. Monitor actual fees, returns, contribution and stock movement. Set a limit for the test and a decision point for replenishment.
