For companies with partner sales, the request often sounds simple: we need a B2B portal, an external API, and order in product cards.
A platform will not help if the landscape is not defined
Then the discussion brings in PIM, MDM, 1C or ERP, an integration bus, API Gateway, a partner portal, order statuses, documents, stock, prices, and access control.
The mistake starts when this set is immediately turned into a platform selection.
In practice, first you need to understand which business scenario must work without a manager, what data it needs, which system is the master system for each domain, and where responsibility boundaries lie.
Otherwise, PIM starts storing what should live in the accounting system, the B2B portal takes on integration-layer functions, and the external API becomes a collection of exceptions that nobody can maintain.
A pre-project assessment in this landscape is needed not for the sake of a large document.
Its task is to provide a management basis for the next decision:
- what to implement
- in what order
- which architecture to defend
- which risks to accept
- which budget to estimate
