A purchase flow defines the way you bill users, when they create a booking or purchase an item through the sign-up page or the e-shop. In OfficeRnD, you can configure how different member groups (active vs drop-ins) purchase any service available for them.
Hint: We recommend unchecking all options for active members. Why? Usually, active members are invoiced once per month with the automatic/manual bill run. If the purchase flow also generates invoices, they will receive multiple invoices throughout the month for every paid booking they make or new service they purchase.
