We have what we call Auto Pay or thru bank payments. For some, they use Credit Cards.
For Auto Pay, I believe that it will be automatically deducted from your registered card on a given specific date. Advantages are you don't need to worry about late payments because it's automatic and no need to confirm the said payment because it's automatic.
Bank payments are okay as well. You can check if your bank offers online bill payment services. If they do, you can use and process online. Advantages are it's easy to process and won't take long.
However, Disadvantages for both methods are:
For Auto Pay, If you are no longer subscribed to a said product or service they will still deduct the amount registered because if you are no longer a subscriber you need to cancel your online transaction.
Another thing is if there were technical errors they could deduct twice of the amount that you are not aware of.
For Bank payments, If you lose the mobile number registered for the card used, It will be hard to make transactions.
You cannot be sure of safety as well since hackers online are getting better as well.
