Frequently asked questions
Find information for getting started and using the service.
If I build a PG, can I also use the merchant app?
A merchant app supports manual-entry payments, transaction history, deposit tracking and settlement requests. We agree on interfaces, operating systems and PG integration to include with your implementation.
How long does it take to build a PG?
Timing depends on payment methods, development, migration and testing scope. Share your target launch date and current systems so we can outline implementation, testing and migration stages.
How is the PG implementation cost determined?
Quotes reflect the base solution, additional capabilities, integrations and infrastructure and data migration. Implementation costs are distinguished from post-launch operating costs.
Which express checkout services can be integrated?
We support integrations including Samsung Pay, Naver Pay, Kakao Pay, PAYCO, Toss and KB Pay. External payment provider integration is distinct from building your own branded checkout, and remains subject to the selected PG and partner contracts.
For what services is prepaid payment used?
Use prepaid balances for payments in your app, website and stores. Alongside top-ups, balance management and refunds, the system supports automatic top-ups, member transfers and merchant settlement.
How do I start using wiezon Cloud?
After contracting, we configure payment, prepaid, merchant and settlement settings and issue user accounts. The base platform needs no separate development; optional features and external integrations are scoped separately.
How are cloud usage fees determined?
Fees reflect your service environment, transaction and sales volumes, and required functions. Base fees are distinguished from optional features and integration costs.
Can I add or cancel features while using the cloud?
You can add or cancel optional features even after signing the contract. Functions requiring additional development will be discussed separately, and changes to the application schedule and usage fees will be notified in accordance with the contract terms.
How do wiezon Solution and wiezon Cloud differ?
A PG implementation delivers a dedicated payment system into your environment. Wiezon Cloud provides payment, prepaid and management functions as a cloud service. Choose between starting with existing capabilities and building a dedicated system.
