Determine the issuer's legal form, tax status and current obligation before assigning an electronic route. This review does not publish a fresh individual-business turnover threshold from an old English overview. NTS operating guidance distinguishes electronic tax-invoice issuance from a simple message announcing that an invoice exists. A link or SMS alone does not complete issuance in the circumstances described; signing and delivery through the specified mechanism matter. [NTS electronic invoice guidance](https://www.nts.go.kr/nts/cm/cntnts/cntntsView.do?cntntsId=7789&mi=2458) B2B tax invoices, consumer cash receipts and card evidence are distinct processes. B2G purchasing references add another layer. Cross-border services and exports require separate VAT and document decisions rather than automatic treatment as ordinary domestic electronic invoices. ### Invoice lifecycle and data NTS published provider registration and electronic tax-invoice standard certification rules dated 11 May 2026, covering issuance, transmission and operating responsibilities. An integration should therefore be assessed against current technical governance, not merely a vendor's claim to produce invoice files. [NTS 2026 system-provider notice](https://g.nts.go.kr/nts/na/ntt/selectNttInfo.do?mi=2205&nttSn=1351085) Record issuer and recipient business identifiers, document type, supply date, tax values, signing mechanism and NTS transmission result. Keep recipient delivery evidence separate from tax transmission and commercial acceptance. A successful email should not automatically close the NTS reporting queue. For corrections, preserve the original invoice relationship and use the applicable modification reason and supported issue process. A customer's refusal to pay is not by itself evidence that the fiscal document should disappear. ### ERP implications Ask the implementer to demonstrate the exact domestic service, permissions, certificate management and acknowledgement mapping. Test expired credentials, rejected tax identifiers and a correction linked to an original document. For incoming invoices, match both document identity and supplier identity before posting. Maintain a queue for invoices visible in the tax system but not yet approved against a purchase order or receipt. Accounting should explain timing differences instead of using tax-system availability as payment approval. For retail operations, document the separate cash-receipt or card process and prevent the same sale from becoming duplicate revenue when several evidence feeds arrive. ### Sources and evidence limits The Korean-language operating page and 2026 provider notice were directly readable on 17 October 2026. The copy deliberately leaves current threshold calculations, exceptions and exact transmission deadlines to an entity-specific legal check. It does not claim a tested ERP connection or universal domestic schema for overseas transactions. **Limitations:** Current individual-business threshold and universal transaction deadlines not independently established.
