Data updates within Sellics occur in different cycles for all the different features:
Profit - Live
This data is transmitted by Amazon's MWS API and is live.
Keyword Rankings - Daily
For all monitored keywords the rankings will be crawled on a daily basis for your "Monitored Products", as well as for all "Other Products".
Reviews - Daily
For all Monitored Products Sellics will crawl all reviews on Amazon daily at night.
Prices, Salesranks, Buybox status - Daily
This data is retrieved daily at night via Amazon's API for all Monitored Products.
Spy Sales (Stock Levels) - Daily
The Spy will crawl the stock levels and thus sales for all tracked products on a daily basis.
Product Texts (Title, Bulletpoints, Description) - Daily / After New Order
For all Monitored Products in the Cockpit and under Rankings this information is updated daily at night.
For the "Other Products", as well products in Profit and Inventory, this content will be updated as soon as Amazon's API transmits a new order.
Inventory - Daily
Inventory levels are updated live via the orders transmitted to the Profit dashbaord.
There can be minor synchronisation differences for uncompleted orders between Seller Central and Amazon's API though. The actual inventory level is transmitted via the API on a daily basis, so that these differences will constantly be corrected.
PPC Manager - Daily
The main data (ie. sales, costs & co.) is transmitted by Amazon's Advertising API on a daily basis for the day prior to today. This is also why you will never see PPC costs in the Profit dashboard when looking at "today".
New campagins will also appear on the next day - if they already generated impressions.
Changes in Keyword Structures (eg. moving Keywords between adgroups) and Bids should be synchronized each hour, at the latest though on a daily basis. It is recommended to make all changes within Sellics though, so that they appear within the Analyze section and Change Log.
Performance - Daily
This data is registered daily from the Seller Central business reports for the day prior to today.
Product Detector - Every 3-4 Months
This database is usually updated (crawled) every quarter of the year.
Due to highly complex restructuring work on a new international database, this has been postponed for quite some time now and will presumably be updated again in Q2 2018 in a new version.
