PIM system comparisons online are usually written by the vendors of those systems. This one is different - I write it as someone who implements them for clients and lives with the consequences of bad architectural choices. I evaluate UnoPIM, Akeneo CE, Pimcore, AtroPIM and LibrePIM from the perspective of implementation cost, infrastructure requirements and e-commerce integration realities.

I explain exactly what you need, what architectural decisions to make before installation, and where the traps are that you only find in production.

PIM in B2B e-commerce - when Excel stops being enough and what replaces it

B2B is not B2C with hidden prices. A wrong product description in a consumer store means a 30 PLN return. A wrong technical datasheet in an industrial tender means losing a 200,000 PLN contract. I break down what PIM actually solves in B2B - and what it will not solve, no matter what the agency promised.
