The platform

202 features. One quiet tool.

OpenSlot replaces the diary, the client book, the till, the inbox and the website — without becoming the kind of bloated suite you have to learn for a month. Everything below is checked against what actually ships.

Everything, listed

202 features. No asterisks.

Every one of these was checked against the shipping product before it went on this page. 196 are included free, 2 are charged on what you use, and 4 are honestly marked as not ready yet.
