## What you need to know

### How should ecommerce platform costs be compared?

Compare the same requirements and operating scenario across subscription, transaction, payment, app, development, labor, infrastructure, risk and exit costs.

### Monthly fee vs total cost: which matters more?

Total cost matters for the decision; the monthly fee is only one visible component and can be lower while operating cost is higher.

### How do transaction fees affect platform cost?

Apply fee rules to expected transaction mix, revenue and payment route, including thresholds and exceptions, rather than comparing headline percentages alone.

### How do payment fees affect platform economics?

Payment costs affect contribution and may vary by method, country, currency, disputes, refunds and provider arrangement.

### How do app costs affect platform economics?

Apps add license and usage cost plus integration, administration, data, performance and dependency cost.

### How do development requirements affect platform cost?

Custom gaps create discovery, implementation, testing, deployment, and maintenance costs that must be included in the platform scenario.

### How does operational complexity affect platform cost?

Complex configuration, fragmented tools, and weak workflows increase training, error, support and change cost even when software fees remain unchanged.

### A quick store check

Compare two platform scenarios using the same order mix, payment methods, apps, development, and operating workload.
