A useful platform comparison starts with the work your business needs to do. Your current bills, supplier proposals and operating responsibilities give that comparison a foundation. A platform subscription is one cost; the people, apps, integrations and changes needed to run the store belong beside it.
Use the same scope, period, currency and transaction assumptions for each option. Shopify's current pricing page is a starting point for platform terms. Confirm the applicable country, contract, fees and inclusions in your own offer. Use actual written proposals when comparing another platform or delivery partner.
Build a worksheet that someone can check
| Cost area | Evidence to collect | Question to settle |
|---|---|---|
| Platform and payment processing | Current contract, statements, settlement currency and volume assumptions | Which charges are fixed, variable or conditional? |
| Build and migration | Accepted requirements, written scope, data inventory and testing responsibilities | What is included, and which dependencies need separate work? |
| Apps and integrations | Invoices, installed services, integration owners and renewal terms | Which jobs must continue, and what would replacing them require? |
| Internal staff time | Observed tasks, frequency and time records | Which workload might change, and how will that be measured? |
| Ongoing operation | Support agreement, change capacity, monitoring coverage and release process | Who keeps each part working, and when can work be delivered? |
| Future change or exit | Known roadmap, ownership terms, data export needs and separately priced scenarios | What would trigger additional work? |
Mark each line as verified, quoted, estimated or unknown. Give estimates a source and an owner who will resolve them. Keep alternative assumptions visible instead of hiding them inside a single five-year total.
Keep cash reductions, time and future revenue separate
A cancelled subscription becomes a cash reduction only when billing has actually stopped and its required job remains covered. Moving advertising budget elsewhere is a reallocation. A shorter staff task can release capacity, but it does not automatically reduce payroll. Record those as separate outcomes.
Additional orders belong in a scenario until measured. Document the baseline, denominator, margin, comparison period and relevant trading conditions before claiming a commercial result. A conversion-rate movement cannot be multiplied by existing revenue without a valid model of the underlying traffic, orders and order value.
The Shopify app-waste checklist helps inventory existing app jobs and dependencies. The Working with Sonder planner keeps illustrative cash and staff-time figures separate. Validate its inputs against your own records.
Evaluate AI sales channels as a defined requirement
Shopify's agentic storefronts guide describes eligible stores, channel controls and different buying journeys. ChatGPT discovery leads customers to the online-store checkout; direct checkout on other supported channels depends on activation. Review eligibility and applicable terms before changing settings.
For your cost model, identify the actual channel, required product and policy data, customer support process and reporting available. Discovery or activation does not guarantee demand. Price any missing work explicitly and measure channel-attributed orders separately from general store activity.
Compare ownership before choosing a rebuild
Ask each option to demonstrate the same representative tasks: finding a product, completing an eligible order, reconciling stock and handling a return. Include the awkward cases your team deals with today. Record what the platform handles, what an app handles and what a person still needs to do.
Ongoing care can reduce avoidable drift when its responsibilities are clear. It cannot establish that future rebuild costs are zero. Agree priorities, capacity, delivery timing, monitoring coverage, approvals and escalation arrangements. Custom integrations, headless engineering or broader acquisition work require their own agreed scope.
Our Czarina case describes delivered navigation and contact refinements. Use concrete delivery records like that alongside your own cost evidence. A Shopify Plus requirements review or conversion audit should identify the decision to make, the evidence needed and the next useful action.
