It's a shame. They tried to increase our prices about 800%. I actually liked the software and used it for over 15 years across a couple of services businesses.
They do have this "usage based pricing" where you pay them for each user, but then also for each project and customer, and then a percentage of your billings. It's completely absurd to be paying them a percentage when you receive payments by wire and all they're doing is emailing an invoice.
Anyhow caveat emptor. Looking at their website they do not show the actual pricing. They just say it's "starting from" $9/seat or $14/seat, but you only pay that if you don't use the software at all.
As far as I can tell, what Bending Spoons has figured out is that they can raise prices 8-10x, but only maybe 60-80% of their customers will cancel because it's a big hassle, and so the profits go up massively for a while. They will probably even retain a hard core of say 10% of their original userbase for some time.
If they are taking a percentage of billings, that dwindling 10% will just be the smallest customers.
