E-commerce Models: Stock, Dropship, Print-on-Demand

Before you choose products or build a website, you need to decide how your store will actually get goods to customers. That decision, your fulfilment model, shapes how much money you need to start, how much profit you make per order, how much control you have over quality and delivery, and how much work you do every day. The three most common models for new stores are holding your own stock, dropshipping and print-on-demand. Many successful stores use a mix.

Model 1: Holding your own stock

You buy products in advance, store them, and pack and ship each order yourself or through a fulfilment partner.

• Advantages: higher margins because you buy in bulk; full control over quality, packaging and delivery speed; you can bundle products and create your own brand.
• Disadvantages: you need cash up front; you carry the risk of unsold stock; you need space and systems to track inventory.
• Best for: proven products with steady demand, local delivery businesses, and brands where the unboxing experience matters.

Model 2: Dropshipping

You list products on your store, and when a customer orders, you forward the order to a supplier who ships directly to the customer. You never hold the stock.

• Advantages: very low starting cost; you can test many products quickly; no warehouse needed.
• Disadvantages: lower margins; less control over quality, packaging and delivery times; long delivery times if the supplier is overseas; you are still responsible to the customer when things go wrong.
• Best for: testing demand before committing cash, and niches where customers accept longer delivery times.

Model 3: Print-on-demand

A specialist printer produces items such as T-shirts, mugs, tote bags or posters with your design only after a customer orders, then ships them. It is a form of dropshipping focused on custom designs.

• Advantages: no stock risk; you sell your own designs; easy to add new designs.
• Disadvantages: higher cost per item than bulk printing; limited control over print quality; success depends heavily on design and marketing.
• Best for: designers, creators and communities with a strong identity, such as a church group, a sports club or a local brand.

Worked example: comparing models for one product

Wambui wants to sell branded water bottles to gyms and fitness fans in Nairobi. She compares the models using hypothetical figures, for a bottle that sells at KES 1,500.

Holding stock gives almost double the profit per sale of print-on-demand, but needs KES 275,000 before a single sale. Wambui decides to start with a local dropship supplier to test which designs and sizes sell, then move her best-sellers to bulk stock once she has three months of sales data. This hybrid approach is common: test with low-risk models, scale with stock.

Questions to help you choose

1. How much cash can you commit before your first sale?
2. How fast do your customers expect delivery?
3. How important is quality control and packaging to your brand?
4. Do you have space and time to pack orders?
5. Is the product proven, or do you still need to test demand?

Common mistakes to avoid

• Choosing dropshipping because it seems easy, then losing customers to slow delivery and poor quality.
• Buying large quantities of stock before testing whether people will buy.
• Comparing models on product cost alone and ignoring delivery, packaging, returns and payment fees.
• Assuming you are not responsible for a supplier's mistakes. To the customer, your store is the seller.
• Never revisiting the model as volumes grow and margins could improve.
