## The plan is only one line item

A subscription or hosting package is the starting point. Your actual costs depend on payment processing, extensions, themes and the help you need to build and maintain your store.

## Separate setup from ongoing costs

List design, migration and development separately from monthly software, maintenance and processing. Include internal time so a low software bill does not hide a large workload.

## Model your own sales

Use your expected order count and average order value to estimate variable fees. Ask providers for terms that apply to your country, currency and payment method.

## Check the assumptions

Confirm billing frequency, tax treatment and renewal terms directly with the provider. Test more than one sales scenario before committing to a long contract.
