OK cool
> But now my domains linked to a Google Workspace are being migrated and the billing goes through Squarespace as well. I assume I cannot move Google Workspace billing to Cloudflare?
What? Do I get it right if you're asking if you can keep your Google Workspace but give the money to Cloudflare instead of Google...? (No, Cloudflare is not a financial services company last I checked)
And what does this have to do with migrating your domains..? (After migrating domains you can just delete your Google Workspace if you don't need it anymore = no Google billing consideration)
Seems your post is missing some detail or I'm misreading
