Total cost of ownership is useful when the comparison includes the work the business will actually pay for. A large hypothetical enterprise invoice is not evidence of your future costs.
Define the same scope for each option
Compare staying and improving, upgrading and migrating against the same catalogue, integrations, customer requirements and planning period. Record the currency, tax basis and contract terms. Exclude speculative revenue gains from the confirmed-cost total.
Use source records for every cost line
- Platform contract and payment processing terms.
- Actual Shopify and external app invoices.
- Connector licences, integration maintenance and exception handling.
- Implementation, data preparation, testing and handover.
- Internal merchandising, support and operations effort.
- Overlapping contracts and the ongoing support scope after launch.
Shopify publishes starting Plus pricing and describes variable fees for more complex businesses. The actual proposal remains the commercial source for your business. Shopify Plus pricing.
Keep assumptions visible
A saving based on cancelling an app is a proposal until dependency checks, owner approval and the later bill confirm it. A staff-time estimate is an estimate until it has a work record. A scenario with improved conversion is separate from a measured result.
This guide does not claim a proprietary invoice dataset, universal platform cost, forecasted revenue loss or guaranteed migration payback.
Use the comparison to choose one next action
If the unknown is a contract, get the proposal. If it is an integration, prove a representative data flow. If it is customer experience, review the actual journey. A smaller improvement may resolve the issue without a platform move.
The practical cost register provides the worksheet fields. Explore Shopify design and development once the scope is clear, and use the 12 Boards delivery story as context without treating it as a financial benchmark.
