How long do you guys recomend to wait from doing job to chasing up unpaid payment. I realise that people are often not home when i mow there lawn and i say to them i will leave invoice with bank details payments are due in seven days. ive got some 3 weeks late now last time i got cranky and had some 6 weeks old and i sent an email saying i was raising prices if accounts where not up todate and had all accounts paid with in 2 days. What do you guys think should i ring people that are 2 weeks old. some ill be there to mow there lawn again next week.
