Generally collection letters should be short, but customer should get clear idea about the bill for
which collection is being done. So the bill Number, Amount due etc. should be mentioned. Mentioning all this details is not possible in a very short letter. over and above this, the letter should also mention the problem seller is facing due to non receipt of payment and letters should also mention the steps to be taken by seller on non receipt of payment. Thus, collection letters can not be very short.
