You can switch your plan and billing term (monthly/ yearly) at any time in your dashboard. Log in to your account, go to the Plans & Billing page, and find the “Plans & Pricing” section.
If you upgrade, you’ll only be charged a prorated amount for the difference between your current and new plan, so you won’t be charged twice. If you downgrade, you’ll receive a credit to your Onerep account for the unused time remaining on your current plan.
