My husband and I own a small decorating company and have a selection of clients who we regularly do work for. One couple who are retired in their 70s we did some work for on monday. They generally pay about 2 days later by bank transfer, I think it's a case of when the husband checks his emails and sees the invoice. Anyway, it's now Thursday and we haven't received payment. AIBU to text with a polite reminder or should we wait another day or two?
