FAQs
Need more information about your billing? Check the frequently asked questions below.

If your questions were not answered below, please contact an account representative

1. Can I pay my bill online?
Yes. Click on the Log In link at the top of the page to access your account and pay your bill safely and securely online.
2. Can I have my recurring charges automatically paid via Credit Card or ACH (Automated Clearing House)?
Yes.  Click to complete a Direct Pay Plan Application.
3. Will I be charged extra if my payment is late?
Yes. A 1.5% late fee will be assessed if payment is not received by the due date on the balance due each month.
4. Why is my most recent payment not reflected on my current month invoice?
Your payment has probably not reached our bank and been applied to your account after the present invoice was created and mailed. If the payment you have sent equals the Balance Forward, simply remit payment for the current charges.  If the payment you have sent does not equal the Balance Forward, please call a billing account representative to resolve any differences on your account.
5. Why did I receive an invoice for service or installation when I paid your technician when he was here?
Your payment may have reached our bank after the present invoice was generated.  Please disregard any previous balance if you have already made a payment and remit for any current charges that have not yet been paid.
6. Am I billed for services in advance?
Yes. Interface and its associated companies bill and require payment prior to providing the services.
7. Why am I not receiving my recurring invoice?
You are likely taking advantage of the Direct Pay service or the billing address is incorrect. Please contact a billing account representative as soon as convenient.
8. Why am I charged for a permit fee?
Certain municipalities require security companies to collect alarm permit fees from their residents and remit the fee to the city. This is similar to sales taxes.
9. Why has my auto-payment not been taken and applied to my account?
Your credit card or ACH was declined. The likely reasons are the account is overdrawn/over its limit or the credit card has expired.
10. If my due date shows Due Upon Receipt, what is the actual due date?
Payment is due once the USPS carrier delivers it to your mailbox.  However to avoid late fees, it is recommended to remit payment by the invoice date.
11. When I received my first invoice, the recurring monthly charges were less than my contract amount. Why is there a difference?
You will see a partial month charge for your monthly services based on the prorated period listed on your invoice.
12. Will I receive a charge if my payment is declined due to Non-sufficient funds, I put a stop payment on a check, or I close my bank account before payment is made?
Yes. You will receive a $20 charge for any of the above.
