Each stands on its own. None of them needs the others, and none of them needs a Treepie account.
Treepie also makes seven products for companies — sales, delivery, support, people, finance, marketing and the assistant that reads across them. Those are shared systems. They are priced per person per month because the whole value is that several people see the same record, and somebody has to keep the server running underneath.
These three are the opposite argument. There is no shared record, because there is nobody to share it with. The work happens on one machine, so that is where the software runs and where the data stays. Nothing is synchronised, nothing is administered, and the price is a price rather than a rate.
If you hire someone and two of you need the same contact record, the honest answer is that you have outgrown a personal tool. That is what Treepie Flow is for, and we would rather say so here than sell you a single-user app twice.
One payment buys the app and you own that version permanently. The first 12 months of updates and support are included. After that a renewal — around 40% of the original price — keeps new versions coming. Renewal is optional. Let it lapse and the app keeps working — you simply stop receiving new versions.
14 days to try it before paying, 30 days to change your mind afterwards. All the prices are on one page.
