why lie to them A/J WCLEANING?no need for an explanation!just tell em they will be going up as they are underpriced for ur own price structure!if they dont like it they can find someone else to clean their windows.custys DONT KNOW what it takes to run a successful window cleaning business.the overheads,no sick/holiday pay etc.
im in business to make money and provide a cleaning service!thats it!
if ur regular,reliable,do a good job,friendly and have been cleaning for them for years u should have v.few problems if its a small prudent prise rise.the others ive put up £4/£5 i start with the line "ill have to stop cleaning ur windows unless i put them up considerably as they are v.underpriced!these i hate doing so im not bothered if i lose them but IVE NOT LOST ONE!i now enjoy cleaning them now!!
i will be increasing a lot of my custys every year by a small amount from now on.
