Subscription with Stripe on WordPress (similar to Rentola)

RENTORRA SUBSCRIPTIONS Brief

What we already have

• The Paid Member Subscriptions (PMS) plugin is used with the Stripe Connect payment gateway.
  
  

• For subscriptions, the following are set up:
  
  

  • Sign-up Fee (for example, 10 zł) — charged immediately.
    
    

  • Free Trial (daily trial).
    
    

  • Recurring Price (for example, 100 zł/week), which automatically starts after the trial.
    
    

• Everything works technically: Stripe receives the correct sign_up_fee, the subscription is created correctly.
  
  

• However, Apple Pay (Stripe Checkout) displays not the sign_up_fee amount, but the total subscription cost (Recurring Price), which misleads users (shows "100 zł" instead of "10 zł"). This is a known bug — PMS is aware of it.
  
  

Task

Goal: ensure the correct display of the first payment amount in Apple Pay/Stripe Checkout

1. Problem, briefly:

In the current version:

  — the user pays 10 zł (sign_up_fee), this happens correctly.

  — but Apple Pay shows the amount of 100 zł (recurring price), which scares the UX.

Root of the problem:

  — Stripe Checkout is formed on the PMS server and shows the subscription `amount`, not the `sign_up_fee`.

  — JS workarounds do not help — Apple Pay is already initialized with the wrong amount.

2. Proposed solution:

Plugin fix

• Add dynamic determination of the amount in create_payment_intent() (in class-payment-gateway-stripe-connect.php).
  
  

• If the current payment is indeed sign_up_fee, pass it to amount instead of the regular amount.
  
  

That is:

 if ( $is_first_payment ) {

    $args['amount'] = $this->process_amount( $subscription_plan->get_sign_up_fee(), $currency );

}

• And so that Stripe Checkout shows exactly this amount: Apple Pay will start displaying 10 zł, as intended.
  
  

3. Alternative path (as on https://rentola.bg/):

• The user enters email → Stripe Checkout immediately displays the amount of 10 zł — without plan selection and Apple Pay.
  
  

• After payment, a subscription is automatically created for them (via PMS API).
  
  

• After 3 days — a second payment is created, or they are transferred to a full plan.
  
  

• This is much simpler from a UX perspective and bypasses Apple Pay issues.
  
  

Summary

1. Fix the Apple Pay amount display: show sign_up_fee, not recurring price.
   
   

2. Or replace the flow with: email → instant 10 zł → trial → automatic transition to subscription.
