hi ive a couple like that,i know its hard to knock on the door but youve done the job that they wanted ! if they have not complained they must be happy with the results ! therefore they have to pay, you are not a charity ! its not even about the money,its the priciple.
i leave a statement of account first then if nothing comes in the post i , go back in the evening when the lights are on, as i know there in,when they answer the door,i say hello ! window cleaner i was just passing saw your lights on and wondered if i can collect payment.
basically what your doing is putting them in an embaressing situation,you just need to have bigger balls than them ! i dont let any debt go,without giving me best shot to get money owed.even if its through the small claims court.
you cant get goods from a shop without paying ! and i fee lthe same about my business.
dont let anyone take the pixx good luck,really does my head in when they think they can get somthing for nothing. im off my soap box now,good luck
