When you turn on the blender, everything gets mixed up anyway, so it doesn't matter in which order you fill it. Or? That's not quite right: Liquids first, then light ingredients, and heavy ingredients last (for example, Juice - spinach leaves - banana pieces + frozen). This way, everything will be well chopped and won't splash onto the lid when your blender is at full power. PS: With the stand mixer, it is precisely the opposite since it mixes, so to speak, "upside-down."
