# Troubleshooting

**Cannot Create Invoices**

**Issue:** "Create New" button is disabled or unavailable

**Solutions:**

* Ensure PCC settings are configured for your organization
* Verify your billing details have been submitted
* Wait for CEE Travel Systems finance department verification (1-2 business days)
* Contact TCP support if verification takes longer than expected

***

**Subscription Not Renewing**

**Issue:** Subscription expired despite having credits

**Possible Causes:**

* Marketing wallet credits have expired (check expiration dates)
* Insufficient combined credit in both wallets
* Payment processing issue

**Solutions:**

* Check Balance tab to verify available credit
* Top up Organization Wallet by creating and paying a new invoice
* Contact TCP support if credit should be sufficient

***

**Cannot Access Application**

**Issue:** Application shows "subscription required" message

**Solutions:**

* Check subscription status in Organization Management > Subscriptions
* Verify subscription hasn't expired
* Start a trial or purchase a subscription
* Contact TCP support if you believe subscription should be active

***

**Trial Not Available**

**Issue:** "Not eligible for trial subscription" error

**Reason:** Your organization has previously had a paid subscription for this application. Trials are only available once per organization per application.

**Solution:** Purchase a paid subscription instead

***

**Credit Transfer Not Working**

**Issue:** Cannot transfer credits

**Check:**

* Do you have the correct admin role (Country Admin, Root Admin, or Organization Admin)?
* Is there sufficient credit in the source wallet?
* Is the destination organization ID correct?
