Log in to your account to see and manage a Synergy Business subscription you bought yourself on our website: Your account
Bought through one of our account managers? Your account manager manages your subscription with you: changes to seats, payment, renewal or cancellation go through them, not the account page. If you're not sure who that is: Contact our business team
See your subscription
The Subscriptions list shows each subscription's Product, Amount per year, Next billing date and Status: Active, Trial, Past due, Paused or Canceled.
Change the card you pay with
Click Update payment method beside the subscription and enter the new card on the page that opens. Past due means the last payment didn't go through; update your card, or contact us if you need help: Contact support
Cancel your subscription
Click Cancel beside the subscription and confirm on the page that opens. The subscription stops renewing, and the license it pays for stops working when the subscription ends.
Enter your new serial key after each renewal
Each year the subscription renews, your account gets a new license with a new serial key. Your old key keeps working until the end of the term it was issued for, so enter the new key in Synergy 1 or Synergy 3 on each computer before then. For Synergy 3, see: Enter or change your serial key in Synergy 3
For Synergy 1, see: Enter or change your serial key in Synergy 1
Need more seats?
On your account page, under Licenses, click Add more seats to open the Synergy Business page. Not sure which option fits? Contact our business team
Perpetual license showing Maintenance expired?
A perpetual Synergy Business license keeps working when its maintenance ends; only software updates and technical support stop, and you can still download any version released before your maintenance ended. To renew, click the Maintenance expired label beside the license, then Renew your maintenance.
