How to see who's invited you
Open Settings → Invitations to see any pending organization invitations sent to your email (this is the general team-invitation list shared across the whole Sparky suite — not the invoice-specific invite you accept via a one-time email link the first time a business sends you an invoice; see Invoices for that).
