Why one flat price
Most software in this game charges per user, or sells the useful bits as add-ons. Looks cheap at two staff. Then you hire, and the bill grows every time your business does — a tax on your own growth.
Do the maths at five or six staff and "from $30 a month" isn't $30 anymore. TidyOps is $350 + GST whether you've got three on the tools or thirty. Hire freely. The bill doesn't move.
And $350 a month is about $81 a week. One saved double-booking, one invoice that didn't slip through — that's the week's bill covered.
