Qally's is the research consultancy which I founded and where I am employed. It has already received payment from 3 sources (2 clients, 1 me); when will it receive payment from 4, 5, 6, or 7 sources in total?

Receive payment = money confirmed in main business bank account as judged by receipt date on bank statement. Donations, grants, and invoices count, return transfer for overpayment would not count.
