Hey all....I am looking for some advice on how to deal with a situation...

I have an existing daycare family for 8 months now (when I opened). I am introducing a contract starting January 2012. I am increasing the rate and (finally) going to be charging for stats and sick days. Also, I am requesting payment in advance instead of after care is provided. I am asking for payment on every other Fridays.

Daycare mom read the contract and sent it back to me with her "comments". She said her and her husband are not comfortable paying in advance, and instead they are willing to pay weekly, and if cash if I would like.
I really dont want this because then I will have 4 families paying in advance and one paying after the fact and it just looks like a headache all round. I like all my pay on the same day.

Any ideas why this would be a problem for them? (We are on great terms and have a great relationship and I have never given them a reason for them to think I would take their money and run LOL)

How could I position this back to them and what reasons would you say that you need payment in advance?

Any input or thoughts on thsi matter would be appreciated! Thanks girls!
