Cost-plus pricing adds a markup to your cost and calls that the price. Competitive pricing looks at what rivals charge and sets the price against them. Most guides frame these as rivals and tell you to pick one — cost-plus for simplicity, competitive for the market. That's the wrong question. They don't do the same job: cost-plus tells you the lowest price you can afford, competitive tells you the price that wins the sale. The strongest setup isn't either/or — it's cost-plus as your floor, with competitive pricing working the range above it.
Both strategies are genuinely useful, and both have a blind spot that the other covers.
Cost-plus guarantees you make money but ignores the market — you can be the most profitable retailer with no sales because you're priced above everyone.
Competitive pricing wins the sale but ignores your cost — follow rivals far enough down and you're selling below profit without noticing.
Read as a fight, that's a stalemate. Read correctly, it's a division of labour.
Here's how each works, and how they fit together.
Competitive pricing, discount campaigns and insights in one system.
Strip both to their core and they're answering two different questions about the same product.

Cost-plus starts inside your business.
Add up the landed cost of a product — materials, manufacturing, shipping, handling — and add the markup you need.
It's simple, transparent, and it guarantees that every sale, in isolation, makes money. Its weakness is that it's deaf to the outside world: a cost-plus price can land well above what competitors charge, leaving you profitable on paper and invisible in the market.
Competitive pricing starts outside your business, with what rivals charge for the same product, and positions you against them.
It keeps you in the running where customers compare — which, on the comparison engines that sort by price, is most of the market.
Its weakness is the mirror image of cost-plus: it can follow a competitor down past the point where you still make money, because it isn't looking at your cost at all.
The advice to choose one strategy and commit fails because each one's blind spot is exactly what the other sees.
Go pure cost-plus and you're setting prices as if competitors don't exist.
In a category where shoppers compare — which is every category Reprice's customers sell in — that's not simplicity, it's a slow leak of sales to rivals whose prices you never looked at.
Go pure competitive and you've handed your margin to the market: the moment a desperate competitor cuts, you match it, and nothing stops the slide before it reaches your cost.
Neither failure is hypothetical.
They're the two most common ways e-commerce pricing loses money without anyone noticing.
The teams that price well don't resolve this by choosing.
They resolve it by giving each strategy the job it's actually good at.
Here's the setup that uses both.
Cost-plus sets your floor — the lowest price you'll ever sell a product for, calculated from its real cost plus the minimum margin you need.
Competitive pricing then works freely in the range above that floor, positioning you against rivals wherever it makes sense to.
The floor is the one line competitive rules can never cross.

This is the best of both and the weakness of neither.
You're always competitive where it counts, because the competitive rules are free to track the market.
And you can never sell below profit, because cost-plus has drawn a line underneath that no competitor move can push you through.
When a rival cuts to a price below your floor, you simply stop following at the floor — you don't win that particular race to the bottom, and you shouldn't want to.
It's the same principle as setting pricing rules that protect your margin: the floor is cost-based and fixed, everything above it is competitive and dynamic.
The reason most teams don't run both isn't that they disagree with the logic — it's that doing it by hand is impossible at scale.
A cost-plus floor is only as good as the cost data behind it, and competitive positioning means checking rivals constantly.
Maintaining both across thousands of products in a spreadsheet means one of them is always out of date.
That's what price optimization software is for.
In Reprice, every product carries a cost-based floor and a set of competitive rules at the same time.
The rules keep you positioned against the competitors and products you choose; the floor is checked on every price change before it publishes, so a competitive move can never breach it.
Cost-plus and competitive pricing stop being a choice and become two layers of one system — which is how the best-performing teams in our Black Friday research stayed both competitive and profitable at once.
