I have been looking for answers to these but haven't been able to find anything.
1) Is there a way to set default pricing so I don't need to re-enter for each new client?
2) If there is a way to set a default can a fixed figure be used for PAYG and a percentage for the subscription plans?
3) Can a price update be applied to every client (or selected clients)?
Hi there ZeroGravity, while there isn't a way to set "defaults" for client accounts in the app at present, there is a useful integration that can help you with this - MyCMSetup. I believe it's still free to use, so give it a try and let us know how you go.
I'll also add your vote internally for an update like this, it sure could come in especially handy for folks who regularly create client accounts :)
