You sell on Allegro, orders keep coming, but at the end of the month you look at your margin and a big chunk of it sits with Allegro, not with you. Commission, subscription, paid promotion of listings - it adds up fast. At the same time you're scared to drop Allegro, because that's where your traffic comes from, and a brand-new store starts from zero with no customers. This isn't an either/or call. Allegro vs your own store is the wrong framing - the answer is both at once, wired together through the API, where Allegro stays a sales channel and your store builds your brand and your customer base.
What Allegro actually costs you
Allegro doesn't charge one simple fee. It's several layers that together chew through your margin.
The sales commission depends on the category and usually lands somewhere from a few to low double-digit percent of the order value. On top of that comes the Allegro subscription (business packages, for example), fees for highlighting and promoting listings, and the cost of the Smart program, where you often end up funding the "free" delivery the buyer sees. Put real numbers on it: at 30,000 zł monthly turnover and a combined Allegro cost of 11-13%, you hand the platform 3,300-3,900 zł every month. Over a year that's well past 40,000 zł.
But the commission isn't the expensive part. The expensive part never shows up on the invoice: the person who bought from you is not your customer. They're Allegro's customer. You don't have their email, you can't remarket to them, you can't send a newsletter about a new collection. Next time, Allegro will show your listing next to three cheaper rivals, and you'll pay commission again for "your own" buyer.
What you don't own when you only sell on Allegro
On Allegro you build turnover, not a company. You're missing three things that actually decide what your business is worth.
- A brand. The customer remembers "I bought it on Allegro," not the name of your shop. You can't sell that, and you can't build loyalty on it.
- A customer base. Emails, phone numbers, purchase history - all of it stays on the platform's side. Without it there's no newsletter, no promo notification, no abandoned-cart recovery.
- Cheap traffic channels. On your own store you do SEO, Facebook remarketing, an email list. Every repeat purchase from the same customer costs you close to nothing. On Allegro you pay commission again on every single order.
Your own store flips this logic. The first sale can be pricier than on Allegro, but the second, third and tenth are cheaper, because you already hold the customer's contact and your own channel.
The fix: a store wired to Allegro through the API
I'm not telling you to kill Allegro overnight - that would be shooting yourself in the foot, because you'd lose your traffic before you've built your own. I do it differently: I set up your own store and connect it to Allegro through the API, so both run as one organism.
In practice it looks like this: one stock, one panel. Inventory syncs automatically - a sale on Allegro instantly removes the item from the store and the other way round, so you never sell the same unit twice. You update listings and prices in one place. Orders from both channels land in a shared view. Allegro stays a machine for acquiring new buyers, while the store takes over the people who already know you and grows your base.
I build the store on WooCommerce (fast start, plenty of ready Allegro integrations, BLIK, InPost Paczkomaty) or on Next.js headless when you need speed and custom logic at larger scale. How that works technically and what it costs is laid out in my online store service.
When the store pays off - the math
Numbers instead of theory. Say you hand Allegro 3,500 zł a month in commission and fees.
Your own store with Allegro integration costs from €2,500 (about 10,700 zł) for a solid WooCommerce start, up to €4,000 and more for a headless build. Add hosting and a domain (roughly 300-400 zł a year) plus a payment-aggregator fee on transactions in your own store.
Now the payback mechanism. Assume that after six months 25% of the sales you'd make anyway shift from Allegro to your own store - because returning customers buy directly from your newsletter and remarketing. Out of that 3,500 zł in commission you then genuinely save around 875 zł a month on that slice alone, not counting new sales Allegro would never have handed you. At that pace the store roughly pays for itself in about a year, and from then on it's pure saving plus a growing customer base that's yours forever.
The timeline is predictable: I build the store and wire it to Allegro in 3-4 weeks, the first sale from your own channel usually lands in the first month (if we run ads), and SEO and the email list compound over 2-4 months.
The most common mistake: treating it as a revolution
I've seen it a few times: someone reads about the fees, gets angry at Allegro and switches the account off, expecting customers to find the new store on their own. They won't. With no traffic, a new store is a shop on an empty side street.
The sane order is calm. First we set up the store and sync it with Allegro so nothing gets lost. Then on every Allegro order we slip in a flyer or a discount code for the next purchase in your own store - that's how you legally pull the customer onto your channel. In parallel we start the email list, remarketing and SEO. Allegro keeps working until your own store has grown enough that you decide how much you still want to leave there. It's evolution, not a leap into the void.
If you sell on Allegro and feel the fees are eating your margin while the customers aren't yours - I'll build you an online store wired to Allegro through the API, with BLIK, Paczkomaty and stock sync, so both channels play together. Write to me on the contact page and I'll calculate, on your own numbers, when that store pays for itself - quote in 24 h, free.
FAQ
Allegro vs your own store - which one pays off? Owning both pays off most. Allegro gives you ready traffic and new buyers but cuts your margin with fees and never hands you the customer's contact. Your own store builds a brand, a customer base and cheap return channels (newsletter, remarketing). Wiring the two through the API gives you Allegro's traffic and ownership of the customer at the same time, with no risk of losing sales.
What does selling on Allegro really cost? The cost stacks up from the sales commission (a few to low double-digit percent depending on category), the subscription, paid listing promotion and the Smart program. Together it often lands at 10-15% of turnover. At 30,000 zł monthly sales that's 3,000-4,500 zł a month, over 40,000 zł a year. The most expensive part is that the buyer stays Allegro's customer, not yours.
Can I keep Allegro and have my own store at the same time? Yes, and that's how I usually do it. I wire the store to Allegro through the API: shared stock, automatic inventory sync, one order view. A sale on one channel instantly updates the other, so you never sell the same unit twice. Allegro stays an acquisition channel while the store takes over returning customers.
How long until my own store pays for itself? A store with Allegro integration costs from about 10,700 zł (WooCommerce) upward. If you hand Allegro around 3,500 zł in monthly fees and gradually shift part of your sales onto your own channel, the store typically pays off around the one-year mark. After that it's saving on commission plus a growing customer base that's already yours.
What's better to build the store on - WooCommerce or Next.js? For most sellers WooCommerce is enough to start: fast launch, ready integrations with Allegro, BLIK and Paczkomaty. I pick Next.js headless when you need serious speed, custom logic, or you've grown enough that a standard platform starts to limit you. I match the platform to your scale and plans, not out of habit.
