Digital income
E-Commerce With Outsourced Fulfilment
Selling physical goods someone else stores and ships — third-party logistics, print-on-demand, or dropshipping.
How the money actually reaches you
A customer buys from your storefront or a marketplace listing and pays by card. The processor or marketplace takes its fee and settles to you on a rolling or monthly schedule, holding a reserve where dispute risk is high. The order routes to whoever actually holds the goods: a third-party logistics warehouse you have already paid to stock, a print-on-demand supplier who manufactures per order, or, in the dropshipping version, a supplier who ships directly to the customer and bills you the wholesale cost. Your gross margin is the spread between the retail price and the landed cost of goods, fulfilment and payment fees. The customer-facing obligations — delivery times, returns, refunds, chargebacks — remain entirely yours, no matter who packs the box.
The customer, directly. A payment processor or a marketplace stands between you and the money and takes a fee for it; an app store or platform takes a commission set in its developer terms. What you actually sell may be a file, a licence, access, a physical parcel someone else ships, or the right to call an interface.
Fastest of the three. Card money typically settles to the processor within days and is paid out on a rolling schedule, minus a reserve on new or high-risk accounts. Marketplaces and app stores pay monthly, in arrears, after their own hold period.
Read the payer, the intermediary and the schedule before anything else. Who pays, who sits in the middle taking a share, and how long after the work the money arrives explain most of the difference between these fourteen businesses.
The structural facts
Six lines, in two halves. The first three are what the model takes — money up front, waiting time, and the rhythm of work it never stops needing. The last three are what happens once it earns: how the income fades if nothing new is added, what stops it growing past a point, and what, if anything, stops the next person copying it. A model with no answer to the last two can still pay; it just does not compound.
- Capital to start
- Wide range. Print-on-demand and dropshipping need very little inventory capital; stocked third-party fulfilment needs working capital tied up in goods before a single sale. Every version needs advertising money.
- Time to first dollar
- Fast — a store can be live and taking orders in days. Fast to a first sale is not the same as fast to a profitable one.
- Ongoing effort
- Daily operations: customer service, supplier problems, returns, disputes, and advertising that has to be watched constantly because it is spending money in real time.
- How it decays
- Ad-driven rather than content-driven. Creative fatigues, auction prices move, and performance degrades within weeks unless someone is actively working on it.
- What caps it
- Advertising economics. Scale is bought, and the cost of buying it rises as you go further from the easiest customers, so growth compresses margin instead of expanding it.
- What stops a copycat
- Brand, an owned customer list, exclusive or genuinely differentiated product, and supplier terms competitors cannot match. Reselling a catalogue anyone can access has no moat whatsoever, which is precisely the structural problem with generic dropshipping.
What it costs to run
- Cost of goods and, for stocked models, inventory capital
- Fulfilment, pick-and-pack and shipping
- Advertising, usually the largest line by far
- Storefront platform subscription and apps
- Payment processing, chargeback and dispute fees
- Returns, refunds, damaged goods and customer service
How it typically fails
- Advertising cost per acquired customer exceeds gross margin per order, and volume makes the loss bigger rather than smaller.
- Returns and chargebacks run higher than assumed, and the processor imposes a reserve or terminates the account.
- Long supplier shipping times generate disputes, negative reviews and refunds.
- The product is a generic catalogue item, so competitors appear immediately and compete on price.
- Sales-tax registration and collection are ignored until they become a liability with penalties attached.
Does it sell?
Whether a business can be sold is the plainest test of whether it is an asset or a job. A buyer pays for income that continues without the person who built it, which means verifiable revenue, a customer relationship that transfers, and a distribution channel that does not walk out of the door with the founder. This section describes whether that market exists for this model — not what anything is worth, which no honest public source can give.
Stores trade actively through online-business brokers and marketplaces. Buyers underwrite gross margin after advertising, repeat-purchase rate, supplier contracts and whether the traffic is bought or owned. A store whose revenue disappears when the ad account is switched off is valued as an advertising operation, and it shows in the terms.
