If you own an accommodation rental business, then you need a reliable reservation system. InnHand is a free Internet reservation system for B&Bs, Inns, Guesthouses and other small accommodation. innHand is completely cloud based and so it requires no updates, storage, backups or any other maintenance. In the free version, functionality is limited to basic bookings but the full version includes the possibility to make offline bookings with a dynamic, constantly updated booking calendar for any period. innHand makes it easy to add your accommodation descriptions and of course supports pictures, room descriptions and varying rates with application restrictions such as minimum stay, number of guests, season, sales period etc. If you need something more sophisticated, it's worth upgrading to the full version as it allows you to add invoices, send emails and check-out guests. The main disadvantage of an online booking system such as InnHand is that if the system goes down, your booking system obviously goes offline. The other issue to consider is that most serious businesses will need to upgrade to the full version to offer customers a professional service.
