Baselinker is the switchboard of Polish e-commerce: store, marketplaces, couriers and invoicing all plug into one place - the only question is whether your scale justifies the subscription. For some stores it is the tool they cannot imagine a working day without; for others it is a monthly cost they never use half of. This piece is meant to help you work out which side you are on.
How it works
Baselinker sits in the middle of your sales as an integrator: on one side you plug in the sales sources (a WooCommerce store, Allegro, Erli, Empik, Amazon and so on), on the other the handling tools (couriers, label printers, invoicing software, warehouse). Orders from every channel land on one list, where the automations do their job: status paid, book a courier, print the label, send the invoice, push the tracking number back to the sales channel. The listing manager publishes products from the store onto marketplaces with category mapping; the warehouse module makes sure stock drops everywhere at once.
In practice that means one thing: the packer and the support team do not log into five panels. The whole day happens in one.
What it costs
The pricing is subscription-based and grows with scale - the components are the number of orders per month, the number of sales channels and the modules you use. Always check the current rates on Baselinker’s own site, because they change; the largest players have enterprise tiers negotiated individually. On top of that, one-off: configuration time. Signing up is quick, but a sensible rollout (mappings, automations, testing) is days of work.
The payback maths is mundane: count the hours of manual order handling (retyping, booking couriers, issuing invoices, correcting stock) and multiply by your rate. The more sales channels you have and the more orders pass through human hands, the faster the subscription pays for itself several times over; with a handful of orders from the store alone you are probably paying for a Swiss Army knife to open your post.
Baselinker, a plugin, or a custom integration
- A store-to-Allegro plugin is enough with one marketplace and small scale - I laid out the comparison of the routes in the piece on integrating Allegro with WooCommerce
- Baselinker wins when there are more than one or two channels, or when order handling and shipping are the bottleneck
- A custom integration or ERP makes sense when the processes are unusual and the heart of the company is a stock system - Baselinker can then be a third wheel; I write about that setup in the piece on ERP and e-invoicing integration
These options do not exclude each other, by the way: a common mature setup is an ERP as the source of truth for stock plus Baselinker as the marketplace and shipping layer.
What helps: before you decide, write out your process for handling a single order step by step and count how many steps happen by hand. Baselinker (and every integrator) earns its keep by deleting exactly those steps - if the list is short, you do not need it; if writing it out alone makes you hold your head, the decision made itself.
Frequently asked questions
Does Baselinker replace an online store? No - it is an operations panel, not a shopfront. The store (with your brand, your SEO and margin free of commission) stays your asset; Baselinker handles it. Selling only through marketplaces without your own store is a strategy where the entire customer base belongs to the platforms, not to you.
Can I test it before paying? There is a trial period - use it to connect ONE channel and push real orders through it, not to click around the panel. A dry run tells you nothing.
Who should configure it? You will handle the basics yourself from the vendor’s materials. The automations, the mappings and the link to invoicing under KSeF are worth doing with someone who has seen a dozen or so such rollouts - mistakes in shipping automations cost real money in labels and returns.
