The real cost of card processing for Shopify merchants

See what card processing really costs Shopify merchants — domestic and international — and how much Quidkey Pay by Bank can save at A$50k to A$500k a month.

The real cost of card processing for Shopify merchants

Most merchants know card processing fees exist. Few have sat down and calculated what they add up to across a year.

The number is usually larger than expected. And for Shopify Plus merchants selling internationally, it's often significantly larger.

We built the Quidkey Shopify Fee Calculator so you can see your exact number in 30 seconds. But before you do, here's what the maths looks like at different sales volumes — and why Pay by Bank makes such a difference for high-volume stores.

The card processing rates for Shopify Plus in Australia

For Shopify Plus merchants in Australia, card processing costs are:

Transaction type
Rate
Domestic
1.2% + A$0.30 per order
International (all-in, including 2% FX conversion)
5.0% + A$0.30 per order

With Quidkey Pay by Bank on Shopify, those rates can become:

Transaction type
Rate
Domestic
0.5% + A$0.30 per order
International
2.0% + A$0.30 per order

As an approved Shopify payment partner, Quidkey integrates directly into your existing checkout. Pay by Bank sits alongside cards, and customers who want to pay by card still can.

What the numbers look like in practice

Example 1: A$50,000/month in domestic sales

A store with A$50,000 in monthly domestic sales and an average order value of A$100 (500 orders/month):

Monthly fees
Annual fees
Card processing
A$750
A$9,000
Quidkey Pay by Bank
A$400
A$4,800
Saving
A$350
A$4,200

Example 2: A$200,000/month in domestic sales

A store with A$200,000 in monthly domestic sales and an average order value of A$150 (approx. 1,333 orders/month):

Monthly fees
Annual fees
Card processing
A$2,800
A$33,600
Quidkey Pay by Bank
A$1,400
A$16,800
Saving
A$1,400
A$16,800

Example 3: A$400,000 domestic + A$100,000 international/month

A store with A$500,000 in total monthly sales, split A$400k domestic (2,000 orders) and A$100k international (500 orders), at an average order value of A$200:

Monthly fees
Annual fees
Card processing
A$10,550
A$126,600
Quidkey Pay by Bank
A$4,750
A$57,000
Saving
A$5,800
A$69,600

The international volume is where the gap really widens. At 5% all-in versus 2%, switching even a portion of international orders to Pay by Bank has an outsized impact.
