Most venues do not set out to run on six different systems. It happens gradually: a till goes in, then a stock spreadsheet, then a booking tool, then a website built by someone else, then a reporting dashboard that only the owner ever opens.
Each one works on its own. The difficulty is the space between them. A menu change has to be made in several places. Yesterday's takings have to be exported before they mean anything. A new starter learns four logins instead of one.
ManageHex covers ordering, the kitchen and cashier, stock, events and your customer website together, so an order taken at the table carries through to the kitchen, the bill and the day's figures on its own.
If you are weighing up new software, it is worth counting not only what each tool costs, but how much of your team's time goes on keeping them in step.
