To keep things simple for our bookkeeper (and hopefully for you too), we only accept credit and debit cards.
The way it works is that we bill your card the Tuesday after your service has been performed. After your card has been billed, we will email you the paid invoice for your records. Also, it is worth mentioning that your card information is completely secure and we never actually see your credit information beside the last 4 digits.
P.s. We recommend getting an Air mile or Cashback credit card. That way you can have all the convenience of paying with your card and score a sweet vacation and/or cash back too!
