First Sale Fees / Field guide
A practical budget for your first digital product
Write down the costs that happen before the first sale and the costs that grow with every sale.
Keep three totals
Launch cash is what you must spend before opening. Monthly commitments are what you owe even in a month with no sales. Per-sale costs grow when customers buy.
| Cost type | What to enter | Question to ask |
|---|---|---|
| Before launch | Only tools or assets you must buy upfront. | Can I launch a smaller version with what I already have? |
| Every month | Platform, email, video hosting and other fixed subscriptions. | Would I keep paying if next month had no sales? |
| Every sale | Platform percentage, processing, any fixed payment charge. | What fee base and currency does each charge use? |
A worked example
Suppose a creator sells a $25 workbook to 20 customers. Product revenue is $500. In a hypothetical setup with no subscription, a 5% platform charge costs $25. An example processor charging 2.9% plus $0.30 per payment costs another $20.50. That leaves $454.50 after these modeled fees.
That $454.50 is not profit. The example leaves out refunds, taxes, currency conversion, the creator's time and any other purchases. If the creator adds a $15 monthly tool, the modeled amount falls to $439.50. Use your actual quotes instead of these illustrative rates.
Build the smallest saleable version
A first version needs a clear product, a way to buy it, a way to deliver it and a way to answer a customer's question. Add subscriptions when they solve a problem you have actually encountered. A large software stack is not evidence that a product will sell.
Before accepting orders, check the payment provider's country support and account requirements, the platform's rules for your product, and the delivery flow. Keep some room in the budget for refunds instead of treating every incoming payment as money immediately available to spend.
Review with real numbers
After a month, compare the worksheet with actual charges and sales. Replace estimated processor fees with the amounts on the statement. Note why customers needed help. That gives you a better basis for the next tool purchase than an optimistic sales projection.
