We use this one. Of all the versions I've tried this gets the best results (edit as required):
Dear
At your request and in accordance with our quotation which you accepted we commenced providing our window cleaning services at your property on the 28th April 2014.
Our terms as stated were £12 per visit on a 4 weekly basis and our payment terms were as standard, i.e. within seven days of service provision.
We only ever received payment for the first visit, your windows have been cleaned a further 4 times, on the 30th May for which £12 is still outstanding and following a ‘skip’ at your request in July, on the 4th August, 2nd September and 6th October, all priced at £7 each as there was no access to the rear, despite us having texted you (as agreed) the previous evening to ensure this. The total outstanding is £33.
My franchisee Mr … suspended the service pending payment of the outstanding amount. Despite numerous requests for payment via phone, letter and in person none has been received.
I have to advise you that if payment of the full amount of £33 is not received within 14 days of the date of this letter we will, without further warning, take one of the following options:
1. We will make application to the Small Claims Court – this could incur additional costs
for you as well as adversely affecting your credit rating.
2. We will pass the account to our Debt Collection agency who will pursue you for the full outstanding amount, plus their and our additional costs.
3. We will put the matter in the hands of our solicitors to take whatever steps they deem necessary.
If you wish to avoid incurring the considerable extra costs any of the above will involve you must pay the full amount as stated above.
Please pay by BACS, send a cheque or deliver cash by hand to Mr …. at …..
Yours sincerely,
Ian Lancaster
