I ran out of credits to make selections and use the replace tool

I got an error regarding the replace tool last Thursday, and I was told that the reason it wasn't working was because I ran out of credits. I was also guided by my clientto "select object" rather than "select subject" to isolate pattern heavy garments as a time saving maneaver. (the subject is pre-selected and backgrounds scrubbed by another service). I use generative crop on most images–so they can appear square and place on a grid.

On average, I'm responsible for at least 177 images a week–which is too slow for the client, they want me to get up to 100/day and then have time for revisions after (many meetings about how I can speed up the the time, the select object tool was the topic of our last meeting). They would up it another 100 or so images a week if I could handle it.

And then generative crop has a hard time following suggestions–they'll add brick walls, windows, staircases, vignetting (which I'll have to either paint out or do a second generative fill to remove), ect. We've gone back and forth on how to word it (make plain white wall to match), (extend white wall without vignetting-a total loser), (expand white wall to match, expand plain white wall to match–these commands added windows, banistairs, corners, etc).

For the attached series, I got one image that worked. The prompt was "make plain white wall to match"
