Start with the business model
Ecommerce covers several quite different models — holding your own stock, selling through a marketplace, or dropshipping where a supplier ships goods you never handle — and each has different capital requirements, margins and failure modes. A useful course says which one it teaches and where the margin comes from after product cost, shipping, payment fees and advertising. Material that moves straight to store setup has skipped the arithmetic that decides whether the business works.
Supplier sourcing
Look for a stated method: how suppliers are shortlisted, how samples are ordered and assessed, what lead times and defect rates look like in practice, and what happens when a supplier fails mid-order. A list of directory links is not a sourcing process.
Store setup and daily operations
Check that the course covers the platform you actually intend to use, and that it goes past installing a theme — product pages, shipping zones, tax settings, and the order admin you will be doing every day once sales start.
Fulfilment and delivery expectations
Orders have to reach customers, and delivery windows on cross-border shipping are frequently longer than a storefront implies. Good material covers how orders route to suppliers, what timings are realistic, and how those timings are communicated before someone buys.
Customer acquisition
Many ecommerce courses lean heavily on paid advertising and little else. Check which platforms are covered, whether the material reflects how those ad products work now, whether organic and retention channels get any attention, and whether it deals honestly with testing budgets and with campaigns that simply do not work.
Unit economics and ongoing costs
This is the section that matters most and is most often thin. Look for a worked example: product cost, shipping, transaction fees, advertising spend per order, refunds and returns, and what is left. Separately, check whether platform subscriptions, app fees and any recommended tools are disclosed as costs.
Returns, refunds and chargebacks
Returns are the part most courses skip, and they get harder the further the stock sits from you. A course worth buying covers the policy you publish, who pays return shipping, how a refund is reconciled with a supplier or marketplace, and what a chargeback actually involves.
Whether the material is current
Ad platforms, supplier tools and marketplace policies change constantly, and a course recorded three years ago may teach interfaces that no longer exist. Check when the material was last updated, and treat guaranteed income, fixed timelines and earnings screenshots as warnings rather than as selling points.
