Cash payments can be placed in an envelope with the client's name along with the invoice number or dates of service, and then dropped off at the office's mail slot. Reception is available in the office three days a week, and during that time, we check mail, including any billing information. While we do have cleaning staff entering the office daily, it's important to note that, as with checks, there is always a risk of loss or theft. Therefore, we do not recommend mailing cash as a payment method. For secure transactions, consider other payment methods offered by Tiny Steps Developmental Services.
