Since it seems like there was an update to the pricing/licensing I purchased on Thursday. (Basically, deselecting subscripions didn't increase price by 10€ again and more importantly, licensing isn't limited to 1 machine anymore.)
@Andavari As a software vendor you have to make a tough choice on the licensing model:
Real Subscription Model - low monthly or yearly fee (e.g. Office 365)
Major Relases with upgrade path = V14 costs e.g. 30€ and the upgrade to V15 50% off => 15€ (old versions only receive essential support, like Parallels Desktop)
Major Releases without upgrade path but limited support for older Versions (like Office 2013, 2016 standalones receive only bugfixes, no new features)
Stupid cloud based model to justify annual subscriptions with 100% renewal price (RealVNC went down that road).
Purchase of current release with free upgrades for 12 month (Piriform) - common, but renewal is often discounted. E.g. even on Antivirus the extension for another year is 30-50% off.
Of course, these choices highly depend on the amount of potential customers - in case of Piriform every Windows user. So, the customer base is not a problem for Piriform. What is, is the question if the amount of paying customers would double if the price would get reduced 50%. Or, in software market, where production cost is not related to amount of units sold: Dumping the price to afraction of the current license and almost everyone buys the software. For the latter of course, it needs to become some really essential tool. (Ín case of CCleaner I would try to greatly expand the "Tools-Section"... there's a lot of potential, e.g. scripts to deal with common sync-issues (OneDrive/GDrive Reset for example), trigger Windows 10 clean shutdown [basically a "shutdown -s -t 0"] and so on of which most are simple command-lines, registry settings or GPOs.)
