Shall I start with yaballe?

I found yaballe and it looks good, shall I start with a free plan to get used to it and then proceed to a paid plan? is there any better alternative software? do you have to pay for the most expensive plan in order to make serious sells?

Yaballe is great, it's one of the most reliable platforms and is the most affordable on the market. Has all the features you need. They also support multi-variations

You might not get far with a free plan though, you need more items
