How do you add a payment method to your panel?

More sales are lost on the payment screen than anywhere else in a panel. The customer likes the service, comes to top up their balance, and leaves if the method they use is not there. That makes payment infrastructure a revenue question, not a technical detail.

Which method suits which audience?

Method	Audience	Fee	Note
Credit and debit card	The widest	Around 2-4%	Instant top-up, highest conversion
Bank transfer	Consistent, high value buyers	Low	May need manual approval
Crypto	International and privacy minded buyers	Network fee	Irreversible, no chargeback risk

For a panel selling into Turkey, cards are mandatory and bank transfer is a strong complement. Crypto makes the difference with overseas customers and reseller purchases.

Card infrastructure, setting up PayTR

PayTR is the most widely used option in Turkey. The step most often skipped during setup is the callback address. PayTR sends a notification to your panel when a payment completes. If that address is not defined, the payment goes through but the balance is not credited, and the customer opens a ticket saying their money is gone.

Your panel's payment settings show a notification address specific to you. You need to paste it into the PayTR merchant dashboard under Support and Setup, then Settings, then Notification URL Settings. That single step removes most setup problems.

Build the fee into your price

If the card fee is 3% and your margin is 15%, your real margin is 12%. If you do not account for that gap, you end up working on thin margins on services you thought were profitable.

There are two common answers, build the fee into the price or give a bonus to people who pay by bank transfer. The second one saves you the fee and pushes customers toward higher top-up amounts. The usual practice is 2-5% extra balance on bank transfer top-ups.

Crypto, stay non custodial

If you are going to take crypto, the thing to watch is where the money sits. Solutions that keep the private key with a third party carry risk. A setup where you register your own wallet's public key (xpub) and a new address is derived for each payment means the money comes straight to you, with nobody holding it in between.

Three settings that stop you losing conversions

1. Keep the minimum top-up low. A first time customer wants to start small.
2. Add preset amount buttons. An empty box makes the decision harder.
3. Be clear about where they land after payment. A blank page after payment is the fastest way to lose trust.

Once the payment setup is done, always run a small test top-up with your own card and watch the balance land.
