A BaseLinker Alternative: What to Look For When Choosing an Online Sales Management System

For years, BaseLinker was the default choice for sellers who wanted to tie Allegro, their online shop and couriers together in a single panel. Once the pricing shifted to a base fee plus a commission on every order model, more and more shops began to work out what that convenience really costs them — and to look for a solution whose price doesn’t grow in lockstep with their sales.

This guide is a practical checklist. We’ll walk through six criteria that genuinely decide whether a migration pays off or ends in yet another compromise.

Why sellers look for an alternative

There are usually three reasons, and they most often appear together:

• Cost grows with volume. A commission on every order means the better you sell, the more you hand back — and margins in e-commerce are thin to begin with.
• You pay for features you never use. A sprawling system comes with dozens of modules, of which you might use five. The rest is cost and noise in the interface.
• Lock-in to a single vendor. Your whole operation runs through one panel, so every change to pricing or terms hits you immediately and in full.

An alternative only makes sense if it solves all three at once — rather than moving the problem somewhere else. That’s why it’s worth checking the criteria below before you decide.

1. Pricing model: do you pay for scale or for every order?

This is the key question: how does the bill grow as sales grow?

• Per-order — you pay for every order. Convenient at the start, painful at volume and unpredictable in peak season.
• A package with a limit plus overage — a flat fee with a generous order allowance included, and only above that a small top-up per additional order. The cost is predictable and doesn’t scale linearly with turnover.

Rule of thumb: if your margin per order is low, a per-order commission eats into it faster than you’d expect. Work out the cost at your target volume a year from now, not at today’s.

Watch out for hidden costs too: fees for extra user accounts, for integrations, for API calls, or a commission calculated on the value of your sales. With the Sellaro pricing you pay a flat rate with an order allowance included, we bill any overage at a single low per-order rate, and we take no commission on sales value.

2. Integrations: do you have everything you need — today and tomorrow?

A good alternative has to cover your channels now and the ones you’ll add later:

1. Marketplaces — Allegro (often several accounts), Amazon.
2. Shops — WooCommerce, PrestaShop, Shopify, Sylius.
3. Couriers — InPost, DPD, DHL, Orlen Paczka.
4. Accounting — automatic invoices (Fakturownia, wFirma).

The most important question isn’t “how many integrations do you have”, but “will you add the one I’m missing — and on what terms?”. Every vendor’s connector catalogue is finite; the difference lies in whether they’ll build the missing integration and what it costs.

With us, the integrations catalogue grows around real customer needs — some connectors work today, others arrive as ready-to-install modules, and a missing integration we add free of charge as part of your package.

3. Automations that actually save time

The panel isn’t everything. What counts is how much repetitive work the automation takes off your hands:

• automatic order status changes based on events,
• generating courier labels and invoices once an order is paid,
• email and SMS notifications to the customer after purchase and at dispatch,
• “if event, then action” rules (webhooks to external systems).

Check whether the automations are flexible (your own rules) or rigid (a handful of ready-made scenarios). A flexible event engine grows with your process; a rigid one soon starts to chafe.

4. Inventory and stock synchronisation

The most common pain in multichannel sales is selling a product that’s already out of stock. It happens when every channel keeps its own stock level and knows nothing about the others.

A good system maintains a single, shared stock level and pushes it out to every channel before overselling can happen. When choosing an alternative, ask about:

• synchronisation frequency (hourly or real-time),
• stock reservation at order time (before it drops to zero),
• variant support (size, colour) and multiple warehouses.

A stock overview alone isn’t enough — what matters is how quickly a change in one channel reaches the others.

5. Security and data isolation

With any SaaS it’s worth asking where and how your data is kept. In a shared-database model, every customer’s data sits in one table, separated only by an identifier — which can be risky if a query goes wrong. Isolation at the level of a separate database schema for each customer is a standard not every vendor offers at the base price.

Sellaro keeps each customer’s data in a separate database schema — physical isolation is part of the standard, not an enterprise surcharge.

6. Migration: how long switching really takes

Even the best alternative is pointless if the migration blocks your sales for a week. Ask directly about:

• data import (products, historical orders, customers) and its format,
• the transition period in which both systems run in parallel,
• onboarding support — will the vendor guide you through the process, or leave you with the documentation.

The safest scenario is to connect the new system in parallel, in read-only mode, and switch channels one at a time — so you can back out at any moment.

Frequently asked questions

How does an OMS differ from BaseLinker?

BaseLinker is a specific product that ties sales, inventory and shipping together. An OMS (Order Management System) is the broader category of order-management software — BaseLinker is one of them, but there are also alternatives that differ in pricing model, breadth of integrations and how they store data. When you choose an alternative, you’re comparing different OMS platforms against each other.

How much does a BaseLinker alternative cost?

It depends on the model. In a per-order model you pay for each order, so the cost grows with turnover. In a package model you pay a flat fee with an order allowance included and a low top-up for any overage. At higher volumes the second model is usually cheaper and more predictable — run the numbers for both at your own order count.

Is migrating from BaseLinker difficult?

It doesn’t have to be. The safest approach is to connect the new system in parallel, in read-only mode, and switch channels one at a time — so you can back out at any moment. Ask the vendor about importing products and historical orders, and about onboarding support.

Does a cheaper system mean a worse one?

Not necessarily. A high price often comes down to the model (a commission per order) or to features you don’t use. A cheaper alternative can cover exactly what you need at a predictable cost. What matters is the fit with your process, not the price alone.

Summary: how to make the decision

When choosing a BaseLinker alternative, don’t compare the price on the home page — compare the total cost at your target volume, the range of integrations (and their readiness to add missing ones), the automations that genuinely help, the quality of stock synchronisation, how data is isolated, and a realistic migration plan.

Make a simple table with these six criteria and score each candidate from 1 to 5. The winner is rarely the cheapest on paper — it’s usually the most predictable at the scale you want to operate at a year from now.
