All sums due from any person, firm or corporation by reason of licensing fees imposed by this chapter shall be recoverable at the suit of the city brought against such person in any court of competent jurisdiction. In such suit, in addition to the fee, the city shall be allowed to recover interest at the maximum allowable rate permitted by state law upon all sums due by way of fee, from the date of accrual thereof, any penalty, and all costs of collection, judicial or otherwise, including reasonable attorney fees. Prosecution for an offense against the city arising out of the failure to pay a fee levied by this chapter, regardless of the outcome or its continued pendency, shall not constitute a defense or a bar in any manner to the collection of any fees and penalties, if any are due, as herein provided.
