How to combine price lists and balances?

Question

Database

Good afternoon, how to combine 20-50 price lists and balances into a single database (reference book), given that the same product has different names, the article is not registered for everyone, i.e. there is no explicit criterion for linking goods to each other.
Is there any cloud solution or services for combining price lists, balances?

Answer 1

Answer 2

The second round - other bees (more or less owning the subject area), which will verify all this and add all sorts of grouping features.
The first stage can abstractly be assigned to something like AI, but then this will load the second stage a little more ...
