Shopify Checkout Customization: 7 Changes That Added $130K a Month

One month, a Shopify Plus brand I worked with made $400,000. The next month: $530,000. That’s 32% more. The only big thing we changed was the checkout.

In this article I’ll show you exactly what we changed, element by element, what a good checkout drop rate looks like, what a few points of improvement are worth for a store doing $100,000 a month, and whether Shopify Plus is worth paying for just to get this.

An honest note: this is a month-over-month comparison (the month after launch versus the month before), not an A/B test, and other things can change between two months. That’s exactly why, at the end, I explain why you should test one change at a time.

Every step of the funnel matters; today it’s checkout

Every online store is a funnel: homepage, collection page, product page, cart, checkout, purchase, and what happens after. Every step loses people, and every step multiplies the next one. I covered the whole funnel in Shopify funnel analysis. Here we zoom in on one step.

Why the checkout? Because it’s the most painful place to lose someone. They found the product. They wanted it. They typed their email, maybe their address. And then they left, one click away from paying. You already paid to get them there, so every person you lose at checkout is ad money you’ve already spent.

The number to watch: checkout drop rate

Your checkout drop rate is the share of people who start checkout but never pay. In Shopify Analytics, compare sessions that reached checkout with sessions that completed checkout.

Checkout drop rate	Rating
40–45%	Excellent
46–55%	Good
56–65%	Average (most stores)
Above 65%	Poor

So even a great checkout loses almost half the people who start it. That’s normal. But the difference between average and excellent is huge.

What a few points are worth

Take a store doing $100,000 a month with a $100 average order: 1,000 orders a month. With a 60% drop rate, 2,500 people start checkout every month and only 1,000 finish.

Improvement	Extra orders / month	Extra revenue / month	Extra revenue / year
−2 points (60% → 58%)	+50	+$5,000	+$60,000
−3 points	+75	+$7,500	+$90,000
−4 points	+100	+$10,000	+$120,000

Same traffic, same ad budget, same products. Just fewer people leaving at the last step.

Shopify vs Shopify Plus: is it worth it for the checkout?

Here’s the catch. On standard Shopify you can’t really touch the checkout. You can change your logo and colours and add things to the thank-you page, but you can’t add your own elements inside the checkout steps, where people actually type their card. That’s only possible on Shopify Plus.

The honest math: Plus starts at about $2,300 a month, roughly $2,000 more than Advanced, so about $24,000 a year. Back to our $100,000 store: two points bring $60,000 a year in extra revenue. Even after paying for the products you sold (at a ~40% margin that’s about $24,000 of profit), that covers Plus. At three or four points, Plus pays for itself and makes money on top. And the bigger the store, the faster it pays back: at $300,000 a month, the same two points are worth $180,000 a year.

Most Shopify experts say Plus starts to make sense at around $1 million a year. My math lands in the same place. My rule of thumb:

• Below about $80,000 a month: wait. Fix product pages and cart first; you can do that on any plan.
• Around $100,000 a month: Plus is worth it, if you’ll actually test your checkout.
• Above $200,000 a month: even a one-point improvement pays for it.

The 7 checkout changes, element by element

Here’s everything we added to the checkout page, from top to bottom.

1. Social proof right next to the logo

A real number of happy customers at the top. The first thing people see on the payment page is that hundreds of thousands of people already bought here, and it went fine.

2. A real reservation timer

“Your items are reserved for 14 minutes.” This only works if it’s true: the items really are held for them. A fake countdown that resets destroys trust. A real one gives people a reason to finish now, not later.

3. One-click add-ons

Two matching products, 20% off, with one Add button each. This raises order value. But be careful: anything before payment can also distract people from paying. So this one you always A/B test, and judge on revenue per visitor, not clicks.

4. No surprises

A short line saying the total already includes duties and taxes, with no extra charges on delivery. Unexpected costs are one of the biggest reasons people leave a checkout. Answer that fear before they have it.

5. Take the risk away

“Less than 1% of customers return their order”, plus 30-day money-back returns. People are about to pay. Show them that almost nobody regrets it, and that if they do, they’re covered.

6. Trust badges right above the Pay button

Returns, free shipping, years in business, ethically sourced. And we removed the long legal text that used to sit next to the button. The last thing people read before they pay should make them feel safe, not make them read terms and conditions.

7. Fast ways to pay

Express checkout buttons for people on their phones, and no forced account. Every extra field is one more reason to stop.

The result

The month after the new checkout went live:

Metric	Change
Visitors	−2%
Orders	+36%
Revenue	$400,000 → $530,000 (+32%)

Why you test one change at a time

These results aren’t a guarantee. Every store and every audience is different. What worked on this checkout might do nothing on yours, or even hurt. That’s why I always say: test one change at a time with an A/B test. Half your visitors see the old checkout, half see the new one, and the numbers decide.

Here’s why it matters. On one store, we added customer reviews inside the cart drawer. It sounds like an easy win: more trust, right? Fewer people bought, so we paused it. (That test is here.)

Now imagine we’d launched that review together with five other changes. The total might still look fine, or slightly worse, and we’d never know which change was hurting us. That’s the real risk of changing everything at once:

• one bad element can quietly cancel out three good ones;
• you can’t tell what worked, so you can’t repeat it;
• if sales drop, you don’t know what to roll back, so you throw away the good changes with the bad one.

When you test one change at a time, the wins stack. Three wins of 5% don’t just add up to 15%; they compound to almost 16%. And every test teaches you something about your customers that you can use in the next one.

How to start

1. Find your checkout drop rate in Shopify Analytics.
2. Compare it with the benchmarks above.
3. Pick one change, A/B test it, keep it only if it wins, then move to the next one.

Start with “no surprises” and trust above the Pay button: they’re usually the safest wins.
