How to issue

Seller fills out required values of e-Tax invoice and issues it making e-Signature by proper certificate. At the same time, a notification mail is sent to customer(buyer). Issued e-Tax invoice is going to be filed to NTS in accordance with NTS filing policy user set.

Notices

  • - Prior to test the process of issuing e-Tax invoices, a user(seller)'s certificate must be registered in POPBiLL Test-bed.
  • - In Test-bed, issued e-Tax invoice isn't filed to NTS actually. Process 'File to NTS' is a kind of mock process so only filing result is going to be changed to 'Success'.
  • - Even in Test-bed, the notification mail is sent to a customer(buyer) actually. Must use another e-mail address for the issuance test.

Flow Chart

Invoicer(Seller) saves the information of e-Tax invoice and issues it calling 'RegistIssue' API. User can get a filing result within 20 minute(Maximum : 30 min) from the time the filing started. To cancel the e-Tax invoice is available only before the filing starts and to issue a revised invoice is required to cancel or modify after the filing starts.

Identification Numbering System

Identification numbering system is designed for management of e-Tax invoices. First, the user configures 'Seller Invoice ID'(invoicerMgtKey) and sends invoice data with it to POPBiLL. Then, POPBiLL assigns 'POPBiLL Invoice ID(itemKey)' matching with 'Seller Invoice ID'. When the e-Tax invoice is issued, POPBiLL do assigns 'NTS Confirm Number'(ntsCofrimNum) to file to NTS and it is used for searching in NTS.
