Consultation / Confirmation of development requirements

We will consult with you to gather the information required for the services you wish to introduce, such as billing / settlement methods, development requirements, and vetting / estimates. If you are using (or planning to use) an e-commerce shopping cart or e-commerce site building package, please see to the page below.

Billing Methods (one-time billing, recurring billing)

The two types of billing methods available are one-time billing, which charges a customer each time they purchase a product, and recurring billing, which charges on a regular basis. We will confirm the billing methods needed according to your business’ services.

One-time billing: A billing method that makes charges every time a product is purchased
Recurring billing (simplified): A billing method in which a specified amount is continuously charged on a billing date set by us, such as for monthly usage fees and monthly flat-rate purchases.
Recurring billing (fixed term/pay-as-you-go): A billing method in which you specify the billing dates and amounts for recurring billings.

If you would like to know more about the billing methods, please see the page below.

Settlement Methods (automatic sales, designated sales)

You can choose between the automatic sales and designated sales settlement methods.

Automatic sales: Sales are automatically processed immediately after the customer completes the purchase
Designated sales: Sales are processed by you at your discretion

Payment System Connection Methods (Link type, API type)

Merchants can select the method of connecting their system with our payment systems.

Linked type: Merchants will be redirected from their system to our payment screen to process the payment.
Merchants do not need to prepare their own payment screen.
API type: Payment information is sent between the merchants’ system and our servers to process the payment. Merchants can make payments through their system.

*With our API type connection, you can use credit card payments safely by using our Token Functions, which converts credit card numbers into another string of character. Click here for more information.

If you would like to learn more about our payment system connection methods, please see here.

In principle, any programming language can be used as long as it supports sending and receiving HTTP GET / POST requests.
System specifications for developers and development contractors can be found on the Developer Console technical support site.

Once the above system connection is complete, you will be able to accept payments through the payment methods introduced.
