To enable your members to override the default membership start date when purchasing a membership go to Settings> Membership Plans and edit the relevant membership plan.
Scroll down to the the section called Default Start Dates for Memberships
When a member purchases a membership via an online form or the member app, the start dates for their membership will default automatically to the date of purchase/approval.
Here, you can tick a box to allow your members to override the default start date when purchasing through the mobile app.
You can limit how far the start date can be moved into the future. To do this, simply enter several days, weeks or months.
Members can choose their membership start date when purchasing memberships through the App, Member Portal or via a Waiver.
