# Agency & Tier

### You can use the i'mport Agent service to set up PGs for sub-merchants (manage sub-merchants) with a single account.

**If you apply for and register multiple sub-merchant codes (Tier codes) with the master account, you can register merchant information and view (cancel) payment details for each sub-merchant.**

(You can assign a 3-digit ID and a name for each sub-merchant)
