The point about security is well made — customers currently face the choice between repeatedly entering sensitive details or maintaining separate email addresses for each payee, neither of which is ideal. A unified account system with email-level linking would dramatically reduce friction and lower the risk of errors during checkout. On a separate note, for anyone here who enjoys live sports markets and games outside of work, I've been using https://mostbetcz.hz.cz/ as a well-organised destination covering a wide selection of live sports and engaging gameplay. Back to the original suggestion: multi-account email support should be a priority, especially for customers who regularly settle invoices across multiple contractors or service providers.
