The useful question is what your business will pay to run the store it actually needs. Platform fees are one part of that decision. Apps, integration support, migration work and the people maintaining the experience need their own lines.
This guide helps you build a budget from evidence. It does not present an agency-wide average, a client invoice or a guaranteed saving.
Start with the contract, including the currency
Checked on 7 October 2026, Shopify advertises Plus starting at USD $2,300 a month on a three-year term or USD $2,500 on a one-year term. Its pricing page also describes variable platform fees for more complex, higher-volume businesses. Get the actual proposal for your entity and business model. Check Shopify's current Plus pricing.
For an Australian budget, record the billing currency, exchange-rate assumption, tax treatment, term, renewal date and who is approving it. Keep payment processing and any transaction charges separate. A universal revenue percentage or fee cap should not replace the terms Shopify offers your business.
Build a cost register your team can maintain
| Cost line | Evidence to collect | Decision to make |
|---|---|---|
| Platform and payments | Written contract and processing terms | What applies to each brand, store and sales channel? |
| Apps and external tools | Shopify bills, vendor invoices, usage tiers and renewal terms | Which capabilities does the business need, and who owns each? |
| Integrations | Connector contract and a map of orders, stock, returns and customer data | Who handles failed syncs and changes to either system? |
| Build or migration | Agreed deliverables, data scope, testing and handover | What is included once, and what becomes ongoing work? |
| Support and improvement | Written scope, priorities, response terms and reporting | Who agrees the next change, tests it and approves release? |
| Internal operations | Actual time spent on merchandising, content, support and exceptions | Which tasks are owned internally and which need specialist help? |
Keep one-off costs, recurring costs and usage-based charges apart. An annual subscription is a cash payment and a renewal commitment; dividing it by twelve helps comparison but does not turn it into a cancellable monthly expense.
Review apps without breaking the operation
Compare the installed app list with actual charges. Some tools bill outside Shopify. A tool with no visible widget may still synchronise inventory, create shipping labels, manage subscriptions or support reporting. Record dependencies before deciding that two apps overlap.
Use the Shopify app billing and dependency checklist. A potential saving stays a proposal until the owner approves the change, dependent journeys still work and a subsequent bill confirms the reduction. This review does not authorise deleting an app.
Compare options over the same period
Put staying on the current platform, improving it and migrating into the same worksheet. Use the same currency, tax basis and planning period. Include transition work, overlapping contracts, training and the team needed after launch. Document unknowns instead of filling them with a supposed market average.
Separate a financial scenario from a forecast. If your spreadsheet assumes more orders after a rebuild, identify that assumption and calculate a case without it. A platform move can be worthwhile for operational reasons without a measured revenue uplift.
Turn the budget into an agreed next step
Bring your current bills, the integrations that must keep working and the most important customer journey to the conversation. We can help scope Shopify design and development, maintenance and support or an agreed programme of ongoing Shopify improvement through Snowball.
Our 12 Boards consolidation story illustrates delivery work that belongs in a scope. It does not supply a universal migration price or prove savings for another store.
