You've already paid to win the customer. Now you want the second order, so you reach for the tool every brand reaches for: a promotion. A sitewide sale, a win-back code, a 20% off email to the whole list.
Orders come in, and you report more repeat revenue at the end of the month.
It's all too common to see brands count a $100 repeat order as $100, no matter what it took to get it.
That's an expensive habit. What you keep depends on how much you gave away.
In What is LTV?, we defined LTV as the margin a customer brings in over the whole relationship, after what you spend to win, serve and keep them. That relationship starts with the first order, and the first order matters. (A bad first delivery can cost you the second one. More on that in a later post.)
This post covers one of the five levers from that piece: discounts. Specifically, what you give up to bring a customer back for the orders after the first. You take every dollar of discount on those orders straight off that customer's LTV.
Two customers, two codes, one $100
Picture two customers placing their second order in the same week. (They're illustrative, but you've seen both.)
Sam has a 10% off code from your win-back email. Jordan has 20% off from your sitewide sale. Both check out at $100.
In Shopify, they look identical: two repeat customers, $200 in revenue. On your retention report, they're the same.
But to land at $100, Jordan put $125 of product in the cart. Sam only needed $111. You paid to make every dollar of that product, whether it sold at full price or not.
So you booked the same revenue from both orders and kept different amounts from each.
You kept less on the 20% order
Here's the math. Say your product costs you 40% of its full price. Gross margin is what you keep after product cost and discounts.
Two illustrative repeat orders, each $100 at checkout, for a brand whose product costs 40% of full price. Rounded to the nearest dollar.
Six dollars sounds small. Multiply it out. Across 10,000 repeat orders, it's more than $55,000 in gross margin. And you still pay for shipping, payment fees and everything else out of what's left.
Count the gap one customer at a time
Say Jordan comes back twice a year, and you bring them back with 20% off instead of 10% both times. You keep about $11 less from Jordan every year, from the discount alone. (Still illustrative.)
That's $11 a year off Jordan's LTV, and Jordan didn't spend a dollar less. You gave it away.
On your revenue report, you see discounted gross sales (what customers paid after the code). Put gross margin right next to it. Watch that number if you want to know what a repeat order added to a customer's LTV.
Where you lose margin on repeat orders
Customers often need a reason to come back, and a good offer can be that reason. You lose margin when the offer is bigger or broader than the job needs.
You pay customers who were coming back anyway. When you run a sitewide sale, everyone gets the code, including customers who already planned to reorder. You pay the discount on their orders too.
Customers learn to wait. Send a 20% off email every few weeks, and customers hold off until the next one arrives. You end up discounting orders you could have sold at full price.
So ask a better question about every repeat order: what's the smallest incentive this customer will still come back for?
Three ways to give customers a reason to come back
Repeat-purchase incentives fall into three groups. Each one does a different job.
Brand-funded promotions are the fastest to launch and the easiest to overdo, for the reasons above.
With a loyalty program, you reward the relationship instead of a single purchase. Customers engage most when they can see a reward within reach.
With a customer-funded upgrade, the customer pays a little extra at checkout for something they want, like protection on their order. You use that payment to fund a reward toward their next purchase. When they come back, they're spending something they earned, not answering a promo you sent to everyone.
Customers spend earned rewards differently
Across the brands we work with, we see a pattern. When customers come back to spend CashBack they earned, they buy at better margins than when they come back for one of the brand's own promotions.
It comes down to how the customer thinks about it. A customer with credit in their account thinks, "I earned this. I want to use it." A customer reacting to a sitewide sale is responding to whatever landed in their inbox that week, so you have to set the discount high enough to get noticed.
You can see it at each stage of the customer journey:
At checkout. Everlane customers whose first order included the upgrade spent 11.5% more on repeat orders than those whose first order didn't. They came out ahead in 11 of 12 monthly cohorts.
The reason to come back. Pashion Footwear gives repeat shoppers 10% back in store credit on their next order, a lighter incentive than most sitewide sales, and reports 11.8x ROAS on CashBack-driven revenue.
The repeat order. CANN customers used store credit on 3,400 repeat purchases and spent about $6 for every $1 of credit they redeemed. Customers who started with the upgrade were worth $273, against $218 for those who didn't.
Your repeat-order margin playbook
You don't need new tools for this. You need to see what each repeat order kept, not only what it brought in.
Put gross margin next to revenue. For every repeat order, report what the customer paid and what you kept. If you only look at revenue, Sam and Jordan look the same.
Compare discount depth by source. Group repeat orders by what customers came back for: sitewide sales, win-back codes, loyalty rewards, earned credit. Compare the average discount on each.
Test a smaller offer. Send your usual promotion to one random group of customers and a smaller one to another. If nearly as many customers come back for the smaller offer, the difference is margin you've been giving away.
Mark who pays for every incentive. For each offer, note whether the cost comes out of your margin, the customer's pocket or a partner's.
Cut what doesn't earn its keep. If customers don't come back meaningfully more often for your deepest promotions than for your lighter ones, scale those promotions back.
How Onward helps you keep more of each customer's LTV
Onward is a customer LTV platform. Here's where we pull on the discount lever, and a couple of others it sits next to.
Bring customers back with a smaller discount. Checkout+ is a customer-funded upgrade. Shoppers who opt in get protection on their order, a 90-day satisfaction guarantee and CashBack toward their next one. When they come back to spend it, they buy at better margins than on spray-and-pray promotions sent to the whole list.
Pay for less of the incentive. The customers who opt in pay for Checkout+, so you pay zero SaaS fees. In many cases, we also sponsor part of the CashBack your customers redeem.
Stop losing margin out the back door. With customer scoring and claims automation, you can catch fraudulent protection claims before you pay them.
Let customers fix their own problems. With order editing, order tracking and returns, customers can change an order, check where it is or start a return without contacting support. You handle fewer tickets, and customers who get answers fast are more likely to buy again.
A sale is a sale, until you count what you gave up to get it.
Give up less.
