Both of these are often line-item budgeted at 15–20% of the core contract value for the product. So … You probably can't charge another 15–20% for services and implementation and training for a $99 a month product. Well, maybe you could, but it's probably unprofitable and not worth it. But, as soon as the sale gets into the five figures, consider adding 15–20% for services. You'll probably get it. And plan for charging, and delivering, additional services in mid-five-figure and larger deals. The customers are happy to pay, and in fact, will expect it.
