Case study: how we automated an ecommerce's pricing on Shopify
Selling branded products with tight margins is hard: undercut the market and you lose money, price too high and you don't sell. We solved it with automated pricing on a Shopify store that adjusts prices by itself to protect the margin. This is what we built and what we learned along the way.
The challenge: branded products, thin margins
The client sold premium branded goods in a competitive market. Set the price too high and the sale walked away to a cheaper rival; set it too low and the margin vanished. Doing it by hand across the whole catalog, every day, was simply not realistic.
The solution: Shopify plus automated pricing
We set up a system that scrapes the manufacturer's reference prices, compares them with the Spanish market and adjusts each product's price automatically to keep around a 20% margin. When the market moves, the price moves with it, up or down, without anyone touching it.
The store runs on Shopify because the goal was simple: get selling, with control over the numbers and no fragile setup to babysit.
1. Reading the manufacturer's prices automatically
The brand was a premium German cutlery and outdoor manufacturer. The system reads the up-to-date prices on its website for every reference, so when the manufacturer changes a price list, the store knows straight away.
2. Comparing them with the Spanish market
Those prices are then compared with what the Spanish market charges for the same products. That tells the store where it can sit and still be attractive to the buyer, without starting a race to the bottom.
3. Adjusting each price to hold the margin
With both data points, the system raises or lowers each price until it finds the point that keeps the 20% margin without falling out of the market. No spreadsheets, no reviewing references one by one: the catalog regulates itself.
The result: from 0 to ~€3,000/month
From launch to ~€3,000/month in under a year
With a margin that holds on its own, because the pricing adjusts to the market instead of going stale.
In under a year the store went from zero to around €3,000/month, holding its margin without manual price-watching. The owner stopped worrying about being undercut, because the system reacts to the market faster than a person ever could.
What we learned
- Automating pricing frees up the part that actually matters: strategy and product, not chasing competitor prices all day.
- The margin has to be designed in, not hoped for. Once the rule is clear, the machine enforces it every single day.
- It scales. The same logic works for 50 products or 5,000.
Automated pricing vs. dynamic pricing
The two terms get mixed up, but they aren't the same. Basic pricing automation applies rules you define: a margin floor, a position relative to the market, a maximum change per day. Dynamic pricing goes a step further and lets algorithms change prices based on demand, time of day, stock levels or customer behavior, the way airlines and large marketplaces do.
For most stores selling third-party brands, a rules-based pricing strategy is the right starting point. It's predictable, easy to explain to the business and it protects profit first. Demand-driven algorithms only pay off with high sales volume and enough data to learn from; without that, they make decisions on noise.
When automating your pricing makes sense
It's worth it if one or more of these describes your store:
- You sell many references and reviewing every price by hand isn't realistic.
- Your purchase prices or market prices change often.
- You work with tight margins, where a badly set price means losing either the sale or the profit.
- You depend on a manufacturer or supplier whose price lists change.
If you already review prices manually and margin still slips away, automating will probably pay for itself.
How to set it up without losing control
The software and tools are the easy part. What makes a pricing system work is the business logic you put into it before switching it on.
- Calculate the real margin: start from the full cost of each order, including shipping, payment fees and taxes, not just the purchase price.
- Set a floor and a ceiling: a minimum price the system can never go below and a maximum it can't exceed, so one wrong data point doesn't wreck a product.
- Choose reliable data sources: supplier price lists or feeds where they exist, and market prices only from sources you can read consistently.
- Get alerts for big changes: if a price moves more than you'd expect, someone should review it before it goes live.
- Keep the feeds in sync: if you advertise on Google Shopping, the price in your product feed has to match the one on the page, or Google can disapprove the products.
On Shopify you can do this with a pricing app or with a custom integration through the Shopify API, which is what makes sense when the rules are specific to your business. Either way, the rules matter more than the tool.
If you sell in a price-sensitive market, automated pricing is one of the highest-leverage moves you can make: you protect the margin without living glued to your competitors' prices. It's part of what we do inside ecommerce SEO and Universo Ecommerce.
Frequently asked questions
Yes. With the right setup, prices adjust on their own based on market and margin rules, so you don't have to monitor competitors manually or update prices one by one.
The system compares your cost and the market reference, then sets a price that keeps your target margin. When the market moves, the price moves with it, up or down, automatically.
No. Shopify makes it convenient, but the same pricing logic can be applied to other platforms. What matters is defining the margin rule clearly.
It depends on the source and on how it's done. Reading prices that are publicly displayed is common practice, but the site's terms of use, the volume of requests and data protection rules all matter. We assess that case by case before building a system like this. And when a supplier offers price lists or a product feed, using them is simpler and more reliable than scraping their website.
No. Automated pricing protects the margin on every sale, but it doesn't bring buyers to the store. Sustained growth comes when you also work on acquisition (SEO, content and ads) in a connected way. In this case, the pricing system worked because the catalog, SEO and measurement were already in good shape. A good price only sells if someone sees it.
