Credits are stored in your account and are deducted automatically at the next service visit. So if you have $50 credit stored, and your service visit costs $30, you will have $30 deducted from your credit automatically after the visit, leaving you with $20 in credit remaining for the next visit.
Credits can be earned by inviting friends and neighbors to ezhome. You can refer friends or neighbors by sharing your referral link, or by sending them a postcard or an email. If your friend signs up using your referral link, you will each get credits added to your accounts. You can track the status of people you’ve referred in the Credits & Referrals page of your account.
