laravel spark not charging per member after owner send invitation

I want to charge the owner of the team for the per member, who is joining the team via invitation. I have done everything that spark documentation have and its working fine but I found a problem where if owner invites a user before buying subscription, spark charge per member but after that, if the owner adds more user after buying a subscription then spark does not charge for that user at that particular time, but charges them only in the next subscription. Is there any way, provided by spark, to charge them as they come in the team.

Spark::teamPlan('popular', 'someplan-id')
            ->price(100)
            ->features([
                'Everything'
            ]);
