How do you handle the routine of an online store? Your experience is needed

Hi all! I work with automation in e-commerce and want to understand what tasks online store owners and managers have that consume the most time and nerves. From what I see most often: - manually download and update products; - monitor the balances and prices of suppliers; - notify customers about orders; - generate documents and reports. I want to ask you: 1. What exactly would you like to automate in your store first? 2. Have you tried any ready-made solutions? What did you like and what did you not? 3. Is the speed of work more important to you or the ability to customize everything “for yourself”? I am testing different automation scenarios in parallel and can share my developments. If you are interested, I can show an example or do a small test directly on your task. Very interesting to hear your experience!
