Build a complete Shopify budget covering setup, recurring software, transactions, fulfilment, support and acquisition.
Use three cost layers
Separate one-off setup costs, fixed monthly costs and variable per-order costs. This prevents a low subscription price from hiding development, apps, payment, shipping, returns and marketing expenses.
Platform and plan costs
Compare plans using required staff access, reporting, checkout and international capabilities rather than price alone. Record billing frequency, taxes and promotional conditions. Verify current regional pricing before publication or purchase.
Theme, design and development
Budget for theme licensing, brand assets, content production, configuration, custom sections, data migration and quality assurance. Include future maintenance; a store that only the original developer can update carries an operating risk.
Apps and integrations
For each app, document the business requirement, monthly fee, usage-based charges, permissions, data flow and replacement plan. Include integration monitoring and troubleshooting, not only installation.
Payment and transaction costs
Model payment processing, currency conversion, chargebacks, refunds and any third-party transaction charges. Use the expected payment mix and order value for each target market.
Fulfilment, returns and support
Include storage, pick and pack, packaging, shipping, duties handling, returns, replacements and customer service. International returns can change the economics of a product even when the gross margin appears strong.
Acquisition and cash flow
Advertising, creative production, email tools and promotions should be modelled alongside payment and supplier timing. A profitable order can still create cash pressure when inventory and acquisition are paid before settlement.
Evaluate contribution per order
Calculate revenue minus product cost, discounts, payment, fulfilment, expected returns, variable software and acquisition. Use low, expected and high-cost scenarios before scaling.

Common questions
Is the subscription the main cost?
Often it is not. Acquisition, fulfilment, payment, development and apps can be larger.
Should annual billing always be chosen?
Only after confirming the platform and plan fit. Lower effective monthly cost should not replace validation.
How often should the budget be reviewed?
Review after major app, market, payment or fulfilment changes and compare forecast with actual monthly costs.
