Will create a membership system just like the one you are seeing here, will integrate it with a credit card payment module like PayPal or Stripe. I recommend stripe.com and my second option is PayPal. This is great if you have any kind of membership services and want to charge recurring monthly fee to a customer. They register once, add their credit card info. & the system charges them monthly. This is great and will help you organize your new and future customer's. All you need to do is sit and relax while the system does all that hard work for you. You will require to have a WordPress website, will add a membership payment system for you. You also need SSL certificate on your site. This system also accepts a onetime payment of monthly or yearly membership system.
This monthly charge helps with maintaining your site, changes to the system, upgrading, this system needs to be maintained because it is very delicate and has to be secured for all your billing transactions. Plus secured and just updated every often. The membership helps that we give you all the help needed to run properly and any changes needed.
You will also need a SSL Certificate on your site. SSL will be needed if you are doing credit card transactions, this makes your website more secure and your client more secured and happier. SSL is extra on our website, separate fee's.
If you own a website and want to charge them via a credit card payment system, this is the best option you have. Each customer will need to sign up and create a credit card transaction, payment to your account and then transferred to your bank account.
