Everything about this booking system has been amazing, from its simple design to ease of use! There have also always be great customer support if I need them too when things go wrong (and trust me they do). The only thing i dislike sometimes with Fastbooking it can take some days for my transactions get approved/refunded by banks or credit card companies but otherwise everything else was perfect!! Try out fastBookings first because there are no hidden costs like other competitors offer which may come as surprise at end user level unless stated so far we haven't had any major issues using their platform in terms off refunds etc.. As mentioned above nothing really except taking time before bank approvals gets processed takes more than usual amount of times compared others platforms where payments usually goes trough very quickly after receiving money into our account.
