Annual subscription with changing user counts?
Has anyone had any experience with actively managing their monthly subscription size on an annual subscription? For example, let's say on May 1, I set my subscription size to 1 and check Auto Increase Subscription Size. I have 15 people log in and submit expense reports. Will my June 1 bill for May be 135 (15 * $9)? What happens if I lower the subscription size to 1 for June and do the same process? Ignoring the unbundling fee.
I ask because our expense reports are very cyclical. Some months we have as low as 10 people submitting, others we have 70. I don't want to have to pay for 70 users a month when my real number is usually quite lower.
