Thanks for your question. A 30-day free trial is available before putting any card details into the system, so you can get a feel for how Current RMS would work for your rental business. When you convert to a paying plan after the free trial, there are two options - pay monthly (£35 for the first user, £15 for each additional user) or annual payments. So if you wanted, you could just pay month by month and if you felt Current was unsuitable for your business, you could just cancel your paying account and no more payments would be made to us. I hope this answers you question, thanks.
