Being in the ecommerce space and a possible end user of the product I would charge based on the size of the deal without a monthly fee. The idea being to reduce friction even more than the 30 day free trial. For example: widget costs $20 dollars if 50 people buy and take a percentage of the total so 1% (I would a/b test the percent and possibly ad a flat rate fee per an offer) would be 10 dollars. I think this would align your interests more with the end user. The more they use your product, the more they pay you.
