When you make money, we make money, through the transaction fee.

The transaction fee charged my Simplero is on top of what your payment processor charges, and it's our way of ensuring that our interests are aligned, so our success is tied to your success.

Transaction fees start at 2% and go down all the way to 0%.

They're calculated based on your invoices, which you can find in the left side of your main navigation.

Any negative invoices (credit notes) are deducted from the amount that the transaction fee is calculated on.

However, we do not actually pay you money in any given period, so if your net income in a given 30-day billing period was negative, the negative transaction fee from those credits are lost.

In other words, if in period one you make $130 in sales and then credit $30 of those, and you're on a plan with a 1% transaction fee, you'll pay $1 in transaction fees for that period.  Say in the next period, you only make $10 sales, but you end up crediting $20, that's net revenue for the period of -$10. In that case, we're not going to refund you the $.10 in transaction fee. Sorry.

Generally, though, as long as you have a steady flow of business, this works itself out nicely, and any credit notes will offset the transaction fee on your income.
