How to automate price list processing in OpenCart?

Question

opencart

Good day, colleagues!
I am looking for a solution that will automate the processing of the supplier's price list on CMS OpenCart 1.5.6.1.
The supplier changes information about the availability of goods several times a day.
The provider makes it possible to receive data in csv. The missing product from the price list is removed.
The bulk of the item has already been added.
When processing the price list, it is required to compare the supplier’s article with the article in the store and, if there is a product, then leave it. If not, then turn it off in the store. If a new one is added, then add it.
And I want to do all this automatically, without manual work.
The volume of the price list is 11-13 thousand positions.
Who can advise?

Answer 1

At one time, I was actively looking for free options for solving this problem, but all modules had certain drawbacks. One, for example, every time stupidly deleted and re-created the product, instead of updating, resetting meta tags and so on, the other could not be friends with the timeout and as a result, every attempt to update the catalog simply crashed the server.
As a result, I had to buy a module (I personally took the first option):

The Pricedata service allows you to update prices / availability of goods in Opencart with minimal server load. You can have several suppliers with different price structures, you can set up automatic updates from mail / FTP / supplier's website. If the price list for some reason has ceased to be updated, a notification will be sent.
