1. Volopay cards are preloaded, meaning you can only pay for transactions whose value is lesser than the funds loaded on the card, so please check the 'Card balance for month/Recurring amount every month' balance on your card. If there isn't enough money on your subscription card, your payment may have been refused.
Go to Cards, select the appropriate Card and click on Settings to update balances.
In this case, we advise you to: Check that your current subscription plan isn't above the price set on the budget for your recurring payments card. If not, the payment will fail.
2. You should also check if main Card Balance has enough money for the transaction to go through.
If you have sufficient balance and yet the payment is declined, check our article which helps you to pay with Paypal using Volopay cards.
