Good article with some good comments. Seems especially relevant to TF.
I’d be interested to know how many people use what they purchase here from for a client vs for personal?
Additionally, how often are you upfront with your client when you do purchase something that’s not directly on their behalf (or is not purchased directly through their own Envato Account)?
Unless a potential client comes to me with a specific request either way, I tend to just give them the options and let them decide.
I’d never use a theme, not tell the client, and charge them bespoke prices, but I’ve no problem saying something along the lines of “you might want to consider a theme modification to get a top quality site within your budget and timescale”. Plus smaller jobs are less stressful, and these things often turn into ongoing work.
