In short
Base.com, still known as Baselinker, raised its prices three times: at 1,000 orders a month the Business plan costs 1,269 PLN, 84% more than in mid-2024.
Sellasist is the closest like-for-like replacement, Apilo makes sense with Shoper, xSale suits a company built around Comarch ERP, and SellIntegro is an ERP connector rather than a full OMS.
Migration has its own price: remapping listings, rebuilding automations and running two systems in parallel, so check coverage, what travels with you and the price at next year's volume first.
Base.com, still widely known by its old name Baselinker, is the integrator most Polish sellers run their orders and listings on. It plays the role Channable or plentymarkets play elsewhere in Europe.
Its price list has risen three times in two years, and that is what sends most teams looking for a replacement. The four platforms below are the ones that come up in that search.
All of them are built for the Polish market, so they carry Allegro, which dominates e-commerce in Poland the way Amazon does further west, along with local couriers and Polish invoicing.
Start from the number you are trying to beat. December 2024 took the paid plan to 99 PLN a month plus 0.69 PLN per order, December 2025 to 149 PLN plus 0.79 PLN, and the 2026 list stands at 279 PLN (approx. €65) plus 0.99 PLN per order.
At 1,000 orders a month that comes to 1,269 PLN (approx. €295). The same volume cost 689 PLN (approx. €160) in mid-2024, so the bill is 84% higher two years on.
| Integrator | How you pay | At 500, 1,000, 2,000 and 5,000 orders a month | What to watch |
|---|---|---|---|
| Base.com Business (Baselinker) | 279 PLN a month plus 0.99 PLN per order | 774, 1,269, 2,259 and 5,229 PLN (approx. €180, €295, €525 and €1,215) | Above 5,000 orders or 1 million PLN (approx. €230,000) of monthly GMV the published price ends and Enterprise terms are agreed individually. |
| Apilo | Subscription plans, nothing per order | Flat inside a plan, you move up when a plan limit binds | Owned by Shoper since 2024 and now part of the cyber_Folks group, with more than 650 integrations. Plans cap the number of offers, so measure the cap against your catalogue rather than your order count. |
| Sellasist | Subscription plans | Flat inside a plan | The warehouse module (WMS) is licensed separately. Support runs through a form staffed between 8am and 4pm, so the entry plan carries no phone line. |
| xSale | Subscription quoted per implementation | Depends on the quote | The contract runs for 12 months, so the choice binds you for a year. It comes from Futuriti, a Comarch implementation partner, which shows in how far the ERP support goes. |
| SellIntegro | Licence per connector | Depends on how many connectors you need | It links your ERP (Subiekt, Comarch, WAPRO, enova) to sales channels rather than replacing the integrator. The product that stands in for Base.com one for one is SellRocket, from the same company. |
Base.com scores 2.2 out of 5 on Trustpilot across about 700 reviews, and the split is telling: 57% one star, 36% five stars. The complaints are about price, the praise is about stability and support.
Trial periods differ too. Base.com gives 14 days, Apilo 21 and Sellasist 30, which is usually enough to run one channel end to end before you commit.

Apilo, Sellasist, xSale and SellIntegro publish no per-order rate, so their columns describe the billing model rather than a figure. Amounts in zloty are converted at approximately 4.3 PLN to the euro.
Sellasist has grown popular for its feature set and pricing. It is the closest thing to a like-for-like replacement for Base.com. Highlights:
xSale is another platform with a broad e-commerce toolkit. It suits companies looking to automate their sales processes and run several channels at once. It comes from Futuriti, a Comarch implementation partner. Its main points:
We implement Base.com as a partner
We configure the Base.com integration, automations and modules around your marketplace sales process.
Apilo has been owned by Shoper since 2024 and now sits inside the cyber_Folks group, so the “new player” label it carried a few years ago no longer fits. It offers more than 650 integrations and pairs naturally with a Shoper shop, which is the case where it saves you the most configuration.
The main features of Apilo:
The name is worth getting right, because a garbled version of it circulates online. SellIntegro connects ERP systems with marketplaces, shops and couriers, so it fills the gap between your accounting and your sales channels.
That makes it a different kind of product from the three above. It works best where the ERP is the centre of the operation:
If you want a one for one replacement for Base.com from the same company, that product is SellRocket.
Migration has a price of its own. You remap listings, rebuild automations, move order history and run both systems in parallel for a few weeks, which means a month of double cost and a team doing the work twice.
Three things decide whether that is worth it:
One threshold has no way back. Once you pass 5,000 orders or 1 million PLN (approx. €230,000) of monthly GMV on Base.com, you move to individually negotiated Enterprise terms, and from there you no longer have a public price list to compare against. That comparison is easier to make before you cross the line.
Sellasist is the closest like-for-like replacement. Apilo makes sense when you already run Shoper, xSale suits a company built around Comarch ERP, and SellIntegro answers a different question, the one about the gap between your ERP and your channels.
If the plan is to stay on Base.com and pay for it with fewer hours instead, the setup is described step by step in Base.com from scratch. The wider field, IdoSell included, is in e-commerce integrators in Poland. To check whether a channel carries its own cost at all, use the ROI calculator.
