Syncee counts the file's product numbers.
We do not count how many variants you have, just the product numbers.
If the task contains 6000 products
and you filter these products in your task to 5000
Syncee will count 5000 products. So you will need to purchase a Syncee subscription that allows you to upload 5000 products.
If the task is contains more products than your plan does, the task will NOT be run.
