What would switching actually save?

Compare the same sales on two platforms. The starting numbers are an illustrative example, not a quote.

Use the same currency for every amount. Changing the currency label does not convert your numbers.

Total percentage fee = platform fee + payment processing percentage. If processing is included, count it once. Include fixed processing fees in the per-order field.

Switching costs & ongoing work

Extra work can be negative when work decreases. Lost contribution covers an assumed fall in sales or conversion after moving; 0 means no loss assumed. Unknown costs should not be treated as zero.

Positive = lower modeled cost after moving. Time value is not cash income. Taxes, refunds, disputes and other costs are excluded unless you include them in your inputs.

Check the practical fit

How the example works

40 orders × 50 = 2,000 in monthly sales. Current costs: 29 + (2,000 × 8%) + (40 × 0.30) = 201. Candidate costs: 17 + (2,000 × 3%) + (40 × 0.30) = 89. Monthly cash-cost saving: 112.

One extra hour of admin valued at 25 reduces the monthly economic saving to 87. Six months gives 522, less 50 in setup cash and 150 in setup time: a modeled difference of 322. If extra work rises to five hours per month, the economic saving turns negative.

The candidate’s 17 monthly subscription uses the USD Startup figure in systeme.io’s official pricing FAQ, checked September 13, 2026. All other example figures are assumptions. They are not a current rate quote for a named competitor or processor.

Compare equivalent responsibilities

A storefront, marketplace and merchant-of-record service may handle different work. Check who handles customer tax charges, refunds, support, traffic and subscriptions. Include added work in the calculation and verify regional payment eligibility before moving.

Calculation formulas

Monthly cost = subscription + order value × orders × total percentage fee / 100 + orders × fixed fee. Candidate cost also includes extra monthly cash costs.

Economic saving = current cost − candidate cost − extra monthly hours × hourly time value − assumed lost monthly contribution. Period difference = economic saving × months − setup cash − setup hours × hourly time value.

Cash payback = setup cash / (monthly cash-cost saving − lost contribution). Time-inclusive payback also counts setup and recurring time value. No positive ongoing saving means no payback from that modeled saving.
