Truck Accessories Payment Fees in New Zealand: Their Effect on Margin

The parts of a payment fee

A payment fee usually has more than one line item. The percentage-based charge is calculated by applying the provider’s stated rate to the transaction value. A fixed per-transaction charge is added once to each payment, regardless of the order value. Together, these are the variable costs to assign to each paid order.

Gateway or platform charges are separate when the provider documents them, and may be charged per transaction, per month, or under another stated billing basis. Include only additional costs that appear in the provider’s terms; do not estimate undocumented charges. Check whether listed fees include GST. GST in New Zealand is charged at a rate of 15% (Inland Revenue (Te Tari Taake): https://www.ird.govt.nz/gst) (Source: Inland Revenue (Te Tari Taake)).

Why low-value orders suffer most

A fixed payment charge takes the same dollar amount from every eligible order, so it consumes more of a low-value sale. Assume a $0.30 fixed charge and a 2% percentage charge. On a $40 truck accessory order, the percentage component is $0.80 and the total fee is $1.10. That equals 2.75% of the order value; the fixed charge alone represents 0.75%.

On a $200 order, the percentage component rises to $4.00, while the fixed charge remains $0.30. The total fee is $4.30, or 2.15% of the order. The dollar fee is higher on the larger order, but the fixed component has become a much smaller share of revenue. The percentage charge scales with order value; the fixed charge does not.

This matters when customers buy small brackets, fittings or replacement items rather than a larger bundle. If both orders have the same product margin, the smaller order loses more margin proportionally to payment fees. Use a profit margin calculator to test several order values and identify where a low-value sale leaves too little contribution after its fee.

How to read the worked example

Read the worked example from the transaction value down, keeping each line separate. The order value is the customer’s sale amount before the payment deduction. Apply the provider’s percentage rate to that value to identify the percentage fee; this shows the variable part of the charge. The fixed fee is the separate per-transaction amount, regardless of the order value.

Add the percentage fee and fixed fee to get the total payment fee. That total is the amount removed from the order economics for payment processing, not an additional product cost. Finally, compare it with the margin before payment fees. Subtracting the total fee gives the remaining margin available from the order.

When checking the example, confirm that the percentage rate was applied to the correct order value and that the fixed charge was added once, not multiplied by the order value. Also check whether the example presents fees including or excluding GST, since New Zealand GST is charged at 15% according to Inland Revenue (Te Tari Taake). You can test the same sequence with the profit margin calculator (Source: Inland Revenue (Te Tari Taake)).

Refunds, chargebacks and currency

When an order is refunded, check whether the provider returns the percentage fee, retains the fixed fee, or applies a separate refund charge. Confirm whether the customer receives the full order amount while your store absorbs part of the original processing cost. Compare the retained amount with the order’s gross profit, not just its sales value. ORVX reports refund value against revenue and return rate by units, helping identify whether refunds are eroding particular product or collection margins.

For a chargeback, check the dispute fee, when it is charged, and whether it is reversed if you successfully challenge the claim. Also check whether the original payment fee remains retained, and whether a partial dispute creates a different calculation. A $1,200 accessory order with a $40 gross profit can become loss-making if the provider retains transaction costs and adds a dispute fee.

For another currency, check the conversion rate, any foreign-exchange markup, and whether the rate is set at authorisation, settlement, refund or chargeback. A refund may convert at a different rate, creating a currency gain or loss. Record the provider’s terms and keep currencies separate; ORVX keeps each merchant’s trading currency and never mixes currencies in one figure.

Compare providers on the same order mix

To compare payment providers fairly, give each the same order mix rather than comparing headline rates. Build a test period using identical order values, such as a set of low-, mid- and high-value truck accessory orders, then apply the same payment-method split to every provider. Keep the trading currency in New Zealand dollars and do not combine NZD results with another currency.

Use the same assumptions for refunds, partial refunds, chargebacks and failed payments. State whether each quoted fee is GST-inclusive or GST-exclusive; Inland Revenue (Te Tari Taake) says GST in New Zealand is charged at 15%. Compare the same reporting period and include every applicable percentage fee, fixed fee, currency conversion charge and refund-related charge documented by each provider (Source: Inland Revenue (Te Tari Taake)).

Report total fees, fee dollars per completed order and fees as a percentage of processed sales. Total fees show the cash impact for the period; fee per order exposes the effect on typical baskets; the percentage helps compare periods with different sales volumes. Use the measure that matches the decision, without treating any single measure as a provider ranking.

Turn fee differences into margin decisions

Turn fee data into a pricing input, not a standalone verdict. If a $120 order costs $2.70 to process, the payment cost is 2.25% of sales. Use that realized percentage when checking whether a product or collection still meets its target margin; do not treat it as the product’s full cost. A profit margin calculator can help model the effect alongside product cost and selling price.

Payment-method settings and order minimums address different problems. Compare each payment method’s fee dollars, approval rate and customer use before changing which options are available. A minimum order can reduce the impact of fixed fees on small baskets, but test it against lost conversion and shipping economics. Payment fees should remain separate from freight, packaging, product cost, advertising and other operating expenses, so a change in one does not appear to fix another.

For finance reporting, show payment fees as their own expense and keep revenue on a consistent GST basis. Inland Revenue (Te Tari Taake) states that GST in New Zealand is charged at 15%. Report gross margin before payment costs, then contribution or net margin after them, with the period and order population stated. This makes provider, pricing and minimum-order decisions traceable in your store’s own numbers (Source: Inland Revenue (Te Tari Taake)).

A useful comparison starts with the fee components that actually apply to each transaction, then tests them across the order values and payment outcomes your store handles. Reading percentage and fixed charges separately makes their effect on margin visible without confusing provider pricing with product or fulfilment costs.
