I, the undersigned, understand and agree that payment is due as services are rendered. If for any reason an unpaid balance remains on my account, after 30 days a finance charge will be applied. The finance charge is computed by a periodic rate of 1.75% per month, which is the annual percentage rate of 25%. I am also aware that if this account should be come delinquent, the same shall be responsible for the collection agencies fees. A $15.00 fee will be charged for each returned check.
