Your switch to monthly plans during my project just cost me a lot of money. I'm going back to iStock. Ciao.
Sorry to hear that you are facing issues with Adobe Stock services.
Can you please elaborate on your issue so that we can further assist you?
Sure, I signed up for the monthly because I'd already presented images that the client approved. However, I use about 1-2 image a month. Not enough to sign up for even the smallest plan.
It's just not flexible enough for me. The $9.99/image was great because I can bill clients by the image easily.
I understand your requirements for the image purchase but we don't have any plan for single images or on-demand purchases separately for standard assets.
You can definitely try our Credit packs offerings which might suit your needs as mentioned here: Adobe Stock pricing and membership plan | Adobe Stock
