Hello!
We develop Store Manager for PrestaShop and Automated Product Import addon.
Using them it is possible to set up cron import and update your database every recurring period (for example every night).
All data can be imported automatically. As for the adjustments you have mentioned:
- "the images are located on an external server (the url is in the csv file)"
not a problem , the application handles local as well as remote images
- "in the csv file are about 60.000 products"
Ok, we can set up import to run locally and then to be applied to your live store to avoid server overload. You need to have in the file image URL then.
- "The other functionalities, like mapping the fields, multiply the imported price with a percentages, etc. will be the same."
The application has mapping feature, ability to create price price mark-ups, add missing data on-the-fly etc.
In case you have any questions, you can ask me here or you can Google for the solution and find out more about it (on the site we also have live chat support).
