Looking to Boost Revenue? Check Your Checkout for Margin Leaks First

Most growth conversations start in the same place: how do we get more customers through the door? More ad spend, more channels, more traffic.

It's a fair instinct. But before you pour budget into acquisition, it's worth asking another question: is your checkout leaking margin on every single order you already have?

Because if it is, scaling up doesn't just grow your revenue. It grows your losses too.

The Cost Hiding Behind Your "Flat Rate"

Most merchants think their payment processing cost is one simple number, the flat rate their provider quotes them. In reality, that sticker price is only part of the picture.

We call the real number your Actual Transaction Cost (ATC), and it's made up of far more than the fee you signed up for:

• Sticker price – the flat gateway rate you were quoted
• Interchange and scheme fees – costs paid to card issuer banks and networks like Visa and Mastercard
• Unrecovered return costs – gateway, processing, and fraud fees that don't get refunded when an order does
• FX and cross-border surcharges – extra costs on international transactions
• Point-solution subscriptions – separate tools for fraud prevention and chargeback management

Individually, these look like rounding errors. Added together, they quietly chip away at every order you process, whether it converts, returns, or gets disputed.

Why This Matters More as You Scale

Here's the part that catches most merchants off guard: these hidden costs don't stay flat as you grow. They compound.

A 0.8% leak on your current volume might not seem worth chasing. But run the same leak across double, triple, or ten times the orders, and it becomes a serious drag on your margin, one that gets harder to shift the bigger you get.

Put another way: how many extra units would you need to sell, and how much extra revenue would you need to generate, just to have the same impact on your bottom line as closing that leak today?

Fixing your checkout economics now means every future sale is more profitable, not just more numerous.

Where Trustap Fits In

Trustap Checkout unifies payments, fraud prevention, fulfilment protection, and chargebacks into one transparent, flat fee, cutting ATC by 0.5–4%. No separate subscriptions stacking on top of your processing costs. No surprises buried in your statement.

A few things worth knowing if you're weighing it up:

• Card payments only. Trustap replaces your standard credit and debit card option. Express checkouts like Shop Pay, Apple Pay, Google Pay, and Klarna stay completely untouched.
• Fast payouts, no delays. Built for high-velocity ecommerce, so your cash flow keeps moving exactly as you'd expect.
• No lock-in. Toggle Trustap off directly from your Shopify dashboard.

But Won't an Extra Step Hurt Conversion?

It's the question we hear most, and a fair one to ask. The data says no.

Trustap's ecommerce merchants currently see an average checkout conversion rate of 72%, well above the industry average. An extra step to a secure payment page, similar to how PayPal works, doesn't meaningfully affect whether a customer completes their purchase. What actually drives cart abandonment is unexpected costs, unclear delivery timelines, and forced account creation, not one extra click in a smooth, transparent flow.

The Bottom Line

Every cent you save on transaction fees drops straight to your bottom line as pure profit. Before you spend another pound acquiring new customers, it's worth checking whether your checkout is already costing you more than it should.

Work smarter, not harder. Fix the leak, then scale.
