Switching from another CSS provider
If you're coming from another CSS provider, the process is the same — the switch just doesn't take effect immediately. After your confirmation, a grace period of up to 14 days runs before it becomes effective. Your current provider can shorten or waive it (Google: moving merchant accounts between CSSs).
What happens during this time
- Your ads keep running as before. You don't need to pause anything.
- The advantage only applies once the switch is effective.
- You cancel with your old provider afterwards, not before.
Don't cancel with your old provider first. If that assignment ends before ours takes effect, your account temporarily falls back to Google Shopping — with the margin that is deducted from your bid there.
