Shopify's subscription is only one line in a store budget. Payment processing, apps, stock, fulfillment, and returns can matter more than the plan price. The useful question is how much cash your particular store needs to open and keep taking orders.
This guide separates seven cost categories and shows how to put them in a budget without counting the same expense twice. Use the free Shopify startup cost calculator alongside it. Examples below are planning assumptions, not Shopify quotes or typical merchant results.
Which Shopify costs belong in your budget?
| Cost | When cash leaves | What to check |
|---|---|---|
| Store subscription | Billing renewal, or upfront annually | Country, currency, billing cycle, end of promotion |
| Payment processing | As payments settle | Percentage, fixed fee, card type, refund treatment |
| Additional transaction fees | Depending on payment setup | Provider eligibility and exclusions |
| Apps and services | Their own renewal or usage cycle | Usage bands, minimums, external subscriptions |
| Domain and theme | Purchase and relevant renewals | Introductory versus renewal price |
| Inventory and fulfillment | Often before customer payout | Supplier terms, packaging, labels, replacements |
| International selling and exceptions | Per order or incident | Conversion, disputes, tax tools, duties and returns |
Shopify's billing documentation distinguishes recurring, usage-based, and one-time charges. A budget needs a place for all three.
1. Subscription price and payment timing
Record the actual quote in your admin, including the billing currency. An annual price displayed as a monthly equivalent does not mean twelve small monthly payments. Keep the upfront annual payment in your cash calendar and the monthly equivalent in your operating model.
Separate introductory offers from the ordinary renewal cost. A trial can help you evaluate the platform, but it cannot tell you whether the business works at full price. Our plan and pricing guide explains the broader selection process.
2. Payment processing on each order
A percentage fee and a fixed fee have different effects on a small order. In an illustrative model using 3% plus $0.30, a $10 payment costs $0.60 to process; a $100 payment costs $3.30. Those represent 6% and 3.3% of the respective payments.
Use your provider's actual fee base. Shipping, taxes, international cards, and the payment method can affect the amount charged. Do not copy one advertised domestic card rate across every transaction.
3. Additional transaction fees and exceptions
Payment processing and Shopify's third-party transaction fee are separate concepts. Shopify's third-party provider guidance explains that additional fees can apply; with Shopify Payments activated, PayPal and manual payments are excluded from those third-party fees. Provider charges can still exist. Check your country and specific integration before budgeting.
There is no universal rule that every PayPal order attracts an extra 2%, or that turning on Shopify Payments removes all fees from every other provider. Use the payment setup comparison to identify your actual combination.
4. Apps that grow with usage
Ask each app vendor what changes the bill: contacts, orders, messages, revenue, locations, or an advanced feature. Estimate the bill at your current activity and at twice that activity. A low starting price can be less useful than a predictable total.
Assign an owner and a review date to each subscription. Compare its job with Shopify's built-in capabilities before adding another tool.
5. Domain, theme, and setup purchases
Keep domain renewal, business email, design help, and theme purchases separate. A free theme can be sufficient; buy a paid one because a tested requirement justifies it. A screenshot is not a requirement. Write down the exact behavior you need and test whether your existing theme can deliver it.
6. Inventory, shipping, and returns
Suppose a $50 order has $18 product cost, $2 packaging, $6 shipping, and the example $1.80 processing fee. It contributes $22.20 before fixed expenses and returns. A hypothetical $2 return allowance reduces this to $20.20. With $250 fixed monthly costs, you need 13 comparable orders to cover those costs.
Initial inventory also requires startup cash. Do not deduct that entire purchase again from monthly profit after already accounting for the product cost of units sold. Payout delays and supplier prepayments can create a cash shortfall even in a profitable month.
7. International costs and unusual events
Obtain country-specific quotes for conversion, shipping, duties, tax services, and payment disputes. Treat a refund, a chargeback, and a lost parcel as separate scenarios. They do not necessarily return the same fees or consume the same staff time.
A 15-minute cost review
Gather the current subscription quote, two supplier quotes, the payment fee schedule, and your app list. Enter fixed monthly costs and one representative order in the calculator. Then reduce expected sales by half and add a replacement shipment. If the cash reserve is inadequate, change the launch scope before committing more spending.
Keep the completed worksheet and review it after your first actual bills arrive. The purpose is a budget you can reconcile, not an impressively low opening estimate.
Choose the next practical step
Before selecting a plan, compare Starter and Basic against the selling workflow you need. Then use the trial evaluation scorecard to test that workflow before a longer commitment. For a small catalog, the Big Cartel comparison provides another platform decision to consider.
