Each time you conduct a paid call, the earnings from that Magnifi transaction will accumulate in your Stripe account. You can check your Stripe account balance within the Stripe Dashboard by going to the Balance side-menu.
Stripe bundles each of your transactions into payouts, which are generally deposited weekly to your bank account on a rolling basis (see Stripe's Payout schedule documentation for country-specific terms). This happens automatically - you do not need to manually retrieve funds from Stripe for your own bank account.
Check out the Balance section to see when payouts will be made to your connected bank account.
The Payouts section (Stripe Dashboard -> Balance -> Payouts) shows a history of payouts made to your account. You can click on any payout to see a detailed list of the transactions comprising that particular payout.
