Development of a web service for generating price lists for marketplaces in UkraineProject Description A simple web service (personal account) needs to be developed that will automatically generate price lists for various marketplaces in Ukraine based on one main procurement price list. The goal is to eliminate the need for me to manually create Excel files for each marketplace.Input Data There is one main Excel/CSV price list with procurement prices. It contains approximately: Article Name Brand Category Procurement Price Availability Product Code Barcode (if available) Other fieldsRequired Functionality1. Price List Upload Button Upload Price List Supported formats: Excel CSV After uploading, the system should save the data.2. Price List Generator There should be a list of marketplaces. For example Rozetka Epicenter Prom Kasta Hotline Allo MAUDAU EVA Bigl.ua (the list will expand) Next to each, a button Generate or better if it updates automatically via API every hour3. For Each Marketplace Separate rules with markups according to their commission tables For example Rozetka its own columns its own order its own field names its own price formula Epicenter other fields other columns Prom different template that is, each marketplace has its own export template.4. Price Formation A rules editor needs to be created. For example Procurement × 1.15 or Procurement + 800 UAH or Procurement × 1.18 + 200 UAH or if the price is up to 5000 UAH then markup 20% from 5000 to 15000 15% over 15000 10% that is, everything should be according to their tables5.

Hosting is slowing down the websites. (I have 2 websites) The hosting provider writes the following message: The hosting account consumes more than 100 CPU minutes per day and creates problems for other websites on the server. Exceeding the load violates clause 5.2 of the service provision rules To reduce the negative impact of the load on other users' websites, restrictions may be applied to the hosting account. To analyze the causes of the load, you can use the statistics and graphs from the "Web Server Load" section, as well as reports and statistics for the websites in the "My Websites" section. Additionally, we recommend checking the access logs of the websites in the "My Websites" section, as the load may be caused by a large number of requests from bots. Please take measures to optimize the load on the hosting. For this, we recommend contacting your website developer. What options for solving the issue are there? How exactly can you help?
