How New Zealand Payment Providers Change Shopify Profit

Every example and amount on this page is illustrative. It shows the method and is not a benchmark, a quote or advice.

What this payment-provider profit measure actually captures

The payment-provider profit measure isolates what accepting a completed New Zealand order costs you. It starts with the revenue from delivered orders, then attributes the charges created by processing that payment. Those charges can include the provider’s percentage fee, fixed per-transaction fee, currency-conversion or cross-border charge where applicable, and any Shopify charge that is triggered by the payment route. The result is the order value left after payment collection, before product cost, advertising, shipping, returns overhead, wages, software and other operating costs.

The comparison must be made on the same basis for every provider. Use the provider actually used for the order, the transaction currency, and the fee that was actually charged rather than a headline rate. A New Zealand store may offer cards, bank-based methods, wallets or buy-now-pay-later options, each with different commercial terms and settlement behaviour. The measure therefore answers a narrow question: how much profit did this payment route retain from revenue that was successfully realised?

It should not count cancelled orders or returned orders as realised sales. Refund value still matters, however: a refund can reduce revenue while some payment costs remain incurred. That effect belongs in the reconciliation of the order and refund, rather than being hidden by comparing provider fees with gross checkout value.

This is a payment-cost view, not the store’s complete profit figure. Wider Shopify profit analytics needs product cost, gross profit, advertising contribution, returns, inventory and operating expenses. It may also need customer and collection analysis: a more expensive method could be relevant if it serves a customer group with different repeat behaviour, but this measure does not claim that a provider caused conversion or future demand. Keeping the payment result separate makes those wider profitability decisions auditable.

The formula is simpler than the fee schedules

Convert every fee into an amount attached to the same set of delivered New Zealand orders. The calculation is:

Payment-provider profit = delivered-order revenue − product cost − fulfilment cost − payment-processing fees − Shopify transaction fees − refunds − other provider charges.

Use gross revenue captured from delivered orders, then subtract refunds as a separate line. If your source already reports revenue net of refunds, do not subtract the refund value again. The same rule applies to fees: use the fee actually charged for those orders, rather than a headline rate that ignores fixed charges, minimums or adjustments.

Product cost is the cost assigned to the units sold. Fulfilment cost covers the order-level costs of picking, packing and delivery. Payment-processing fees are what the payment provider charged to authorise and settle the transaction. Shopify transaction fees are a separate line where they apply. Other provider charges can include an attributable chargeback, payout or currency-conversion charge; include it only when it belongs to this order set.

This is a contribution measure, not full business profit. Leave out costs that do not arise from accepting and delivering these orders: rent, salaries, general software, accounting, income tax and other unrelated overheads. Advertising should also remain outside this specific calculation unless the analysis explicitly defines a wider contribution measure.

For margin, divide the result by the same delivered-order revenue base and multiply by 100. Keep the currency consistent throughout. A fee shown in another currency must be converted using the rate and accounting treatment used in your records before it enters the formula. This structure makes a provider’s fee schedule comparable with the actual economic cost of the orders it processed.

Separate Shopify Payments from third-party costs

Keep Shopify Payments and external gateways as separate cost lines. With Shopify Payments, the processor’s percentage fee and fixed per-transaction fee belong against the delivered order. With an external gateway, record that gateway’s processing fee separately, then add any Shopify third-party transaction fee that applies to the store’s plan and payment setup. Do not assume the gateway’s advertised rate is the full cost.

Card surcharges need their own treatment. If the customer pays a surcharge, record the surcharge as order revenue and the related processing cost against the same order; if the surcharge is absorbed, record only the cost. A percentage fee applies to its defined base, which may include shipping, tax, or the surcharge depending on the provider’s terms. A fixed fee applies once per transaction, so splitting one order into multiple payments can change the result even when the order value does not.

Currency conversion can affect both the fee and the amount you actually retain. Separate the customer’s transaction currency, the provider’s converted settlement amount, the conversion spread or fee, and any payout or withdrawal charge. Reconcile the provider payout to the delivered order rather than treating the payout as revenue. ORVX keeps a merchant’s trading currency intact and does not mix currencies in one figure, which makes these adjustments easier to inspect in Shopify profit analytics.

• Shopify Payments: processor percentage fee, fixed fee, conversion cost where applicable, and payout charges.
• External gateway: gateway percentage fee, gateway fixed fee, Shopify third-party transaction fee where applicable, conversion cost, and payout charges.
• Customer card surcharge: include it in revenue only when charged, then match the fee to the same transaction.
• Provider comparison: assess total retained amount, settlement timing, supported payment methods, and conversion performance—not the headline processing rate alone.

A worked New Zealand order with real numbers

Use one delivered order and keep every amount in NZD. Assume the customer pays NZD 150.00, including NZD 12.00 shipping. The merchant’s tax calculation identifies NZD 19.57 as GST, so realized revenue before costs is NZD 130.43. Assume the order contains NZD 54.00 of product cost and the carrier charges NZD 9.00. Shipping therefore contributes NZD 3.00 before payment and Shopify charges.

For a concrete fee illustration, assume the payment provider charges 2.00% plus NZD 0.30 on the NZD 150.00 processed amount, and Shopify charges 1.00% on that same amount. The payment fee is NZD 3.30: NZD 150.00 × 0.02 = NZD 3.00, plus NZD 0.30. The Shopify charge is NZD 1.50. Combined payment-related cost is therefore NZD 4.80. These are scenario inputs for the arithmetic, not a quoted New Zealand tariff; replace them with the rates in the merchant’s agreement.

The order’s calculation is then: NZD 130.43 realized revenue minus NZD 54.00 product cost equals NZD 76.43 before delivery; minus NZD 9.00 carrier cost equals NZD 67.43; minus NZD 4.80 in payment and Shopify charges leaves NZD 62.63. Against the NZD 130.43 realized revenue, that is a 48.01% margin, rounded to two decimal places. The NZD 19.57 GST amount is not added back as profit, and the NZD 12.00 shipping receipt is not treated as free revenue: NZD 9.00 is consumed by the carrier, leaving only NZD 3.00 before the fee deductions.

The fee base is an important edge case. If the provider excludes shipping, the percentage portion would be calculated on NZD 138.00 rather than NZD 150.00, changing the result; the contract and settlement report decide which version is valid. Likewise, a cancellation or return should not remain in this delivered-order example. In Shopify profit analytics, the useful comparison is the same calculation across delivered orders, products, and collections, so a favourable average is not hiding orders whose shipping or fee structure absorbs their margin.

The mistakes that make the number wrong

The first error is applying the percentage fee to the wrong total. A provider may calculate its percentage on the amount actually processed, while your internal profit calculation may use product revenue only. If a customer pays NZD 150, including NZD 12 shipping, a 3% fee on NZD 150 is NZD 4.50; a 3% fee on NZD 138 is NZD 4.14. That NZD 0.36 difference is small on one order but material across hundreds. Check whether the fee base includes shipping, discounts, tax, tips and any other amount sent through checkout.

Do not omit the fixed charge because it looks insignificant. A fee of 2.5% plus NZD 0.30 costs NZD 3.30 on a NZD 120 payment. The percentage alone produces NZD 3.00, understating the cost by 30 cents. That distortion grows when your average order value falls, and it can make a low-value product or campaign appear more profitable than it is. Calculate the fixed component per completed payment, then confirm how the provider treats multiple payment attempts or split payments.

GST creates another mismatch. Comparing a GST-inclusive customer total with a GST-exclusive fee, or treating GST on a provider fee as profit, mixes unlike figures. Keep the revenue basis, fee basis and tax treatment explicit. For example, label each input as GST-inclusive or GST-exclusive before calculating the margin, and use the treatment that matches your accounting records. Do not remove GST from only one side of the calculation.

Refunds also invalidate a simple order-count calculation. A returned order should not remain in realized revenue, while the payment fee may be fully, partly or not at all returned. Record the original charge, refund amount and any fee reversal separately. Otherwise, you can either charge the business twice for one transaction or assume a fee disappeared when it was retained. A refund report that shows both refund value and the affected revenue is more useful than a net payment total alone.

Finally, do not copy the headline rate into your model without reading its conditions. Advertised pricing may depend on the Shopify plan, payment method, domestic versus international card, online versus in-person use, transaction volume, currency conversion or whether the provider is connected as a third-party gateway. Apply the rate to the orders that actually qualify, and include any monthly, setup or gateway charges. Reconcile the result to a provider payout statement in the same trading currency; otherwise, a plausible-looking Shopify profit figure can still be wrong.

Use the result to choose and monitor payment options

Compare payment options by order type, not by one blended fee rate. Split New Zealand orders into low-, mid-, and high-value baskets, plus any materially different payment methods, currencies, devices, or customer groups. Fixed fees matter more on a NZD 30 order than on a NZD 150 order. Also separate new and repeat customers if the checkout experience affects conversion. A provider that costs less on a high-value order may still produce less profit on smaller baskets if it reduces completed checkouts or approvals. In practice, calculate contribution for each cohort with the provider attached. If a NZD 30 order would produce NZD 26.40 before payment costs, a NZD 1.20 realised cost leaves NZD 25.20; a NZD 0.80 cost leaves NZD 25.60. That NZD 0.40 difference is small per order but meaningful when multiplied across the cohort, provided refunds and approval rates remain comparable.

Set a decision threshold before reviewing results. For illustration only, require at least NZD 25 contribution after payment costs and a 15% contribution margin for each order cohort. A provider passes only when its realised result clears the threshold over a meaningful volume, not because one week contains a favourable mix. Include refunds, failed payments, chargebacks, and any Shopify or gateway charges that are allocated to the transaction. Review the same measures by week or month, while recording order count, average order value, approval rate, refund value, and chargeback value beside the result. A falling average cost can be misleading if the provider is receiving more high-value orders or if failed payments are excluded.

Use the threshold as a monitoring rule rather than a one-time selection exercise. Flag a cohort when its contribution falls below the threshold, when approval performance changes, or when refund and chargeback costs alter the realised result. Then investigate the affected method, device, customer group, or basket range before changing providers. If two options both pass, compare the profit retained after accounting for completed orders, not merely the fee on successful transactions. The calculation identifies which option produced the stronger realised economics for the observed period; it does not by itself prove that the provider caused a change in conversion or customer behaviour. Keep the cohort definition and allocation rules unchanged between reviews so that movement in the result remains interpretable.

A New Zealand payment provider changes Shopify profit through more than its headline card rate. Calculate the full cost per order, keep GST treatment consistent, include Shopify’s own transaction charge where applicable, and compare the result with approval rates, conversion and payout reliability. The right choice is the provider that produces the strongest dependable contribution margin for your actual order mix, not simply the lowest advertised percentage.
