Checkout optimization agencies

How much of checkout you can change

On most hosted platforms, checkout is deliberately constrained. Depending on your plan and platform you may be limited to branding and a handful of extension points, with deeper changes requiring an enterprise agreement. Agencies that promise a fully custom checkout on a standard plan are describing either a different platform or a workaround that the platform will eventually close.

So the real work is usually upstream of checkout — on the cart, the shipping estimate, the account prompt — plus careful use of whatever extension mechanism your platform exposes. Ask an agency to name the mechanism. The answer tells you whether they have done this on your platform recently.

What actually moves completion

The consistent findings across stores are unglamorous: show the total cost, including shipping and duty, before the customer has invested effort. Do not require an account. Offer the payment methods your customers already use, which varies enormously by market. Make the error states survivable — a declined card should not empty a cart.

Novel checkout designs rarely beat conventional ones. The wins are in removing surprises, not in invention.

Questions worth asking

• What is the mobile completion rate now, separately? It is almost always materially worse and is where the recoverable money is.
• Which payment methods are missing? This is a market question, not a technical one, and the answer changes the number more than layout does.
• What does the tax and duty line say for international orders? “Calculated at checkout” is the phrase that loses the order.
• Is the abandonment flow counted as part of this? It often is, and it is a different discipline — that is email work.

What it costs

A cart-and-checkout review with a prioritised list is commonly $2,000–$6,000. Implementation of the findings, within platform limits, typically runs $5,000–$25,000. Where a genuinely custom checkout is in scope, the platform licence is usually the dominant cost and the build is quoted against it.
