How many of you operate a text service for your customers before you show up? I've been doing this so far but I've been thinking that I might now start informing any new customers, via a letter I give them on their first clean, that I will be back in 4/6/8 weeks time. Im thinking I tell them the frequency in the letter and the week number it starts on and then, just rock up, do the job and leave a slip. I've only been thinking this because a couple of customers have messed me about lately by texting me back once I've sent them the reminder and giving me reasons why they can't: i.e 'they're pretty clean at the moment, maybe next month' or 'I've had a lot of bills this month and can't afford it'. Don't get me wrong 95% of my customers don't do this. I just want to eliminate the chances of this sort of thing happening again. Your thoughts?
