Laravel and Stripe expert required

Our Laravel application manages subscriptions, creates invoices and then allows the user access to the service in the platform. Users should then be able to manage their payments etc. This all mostly works but we have a handful of bugs where payments are not being marked as paid in our platform when the payment has been received and also some single payment products being shown as subscription products. The only complexity is that SOME of the payments in our application (it's a marketplace) go to the vendor through Stripe connect. We need someone to look at these bugs and help us resolve them ASAP.
