Hey guys, I just joined. I was wanting to see if anyone has worked with the afterpay payment gateway before? A client wants to integrate it onto their site which I can do and have found what I need off github in order to install it. However, I'm not sure what I should charge for this service. Does anyone have a 'rule-of-thumb' when it comes to quoting new enhancements that you're not familiar with? Any help would be greatly appreciated.
