01 — Local economy
Samsung, Hyundai Motor, LG and SK steer their business groups from Seoul, while Yeouido concentrates banks, brokerages and broadcasters. Internet and game companies such as Naver, Kakao, Nexon and NCSoft cluster in Pangyo just south of the city, K-pop agencies including HYBE and SM Entertainment run studios and merchandise operations, and Coupang and other e-commerce firms have built dense same-day delivery networks across the capital region.

What an ERP, billing system or AI agent has to respect here.
| Indirect tax | VAT, standard rate 10%VAT is 10% on most supplies, and the tax invoice is the core document for input-tax credit, with card sales and cash receipts also reported to the National Tax Service (NTS). |
|---|---|
| E-invoicing | Mandatory · Electronic tax invoice (NTS Hometax)Corporations and individual businesses with prior-year supply value of KRW 80 million or more (threshold in effect since 1 July 2024) must issue electronic tax invoices in the NTS XML format with a certificate-based signature and transmit them to the NTS within strict deadlines. |
| Data protection | Personal Information Protection ActStrict and actively enforced by the PIPC; a February 2026 amendment raised maximum penalty surcharges to 10% of total revenue for serious repeat or large-scale violations and broadened incident-reporting duties. |
| AI rules | The AI Basic Act took effect on 22 January 2026 with transparency and labelling duties for generative and high-impact AI and a domestic-representative requirement for certain foreign providers; the government has deferred most fines (up to KRW 30 million) for at least one year. |
| Systems we migrate from or connect to | Douzone Bizon, ECOUNT ERP, Younglimwon Soft Lab, SAP Business One, Oracle NetSuiteMasters, ledgers, stock and open balances move across and are reconciled before cutover. |
| Payment rails for web apps and SaaS | Toss Payments, KG Inicis, NHN KCP, Naver Pay, KakaoPay, Samsung Pay |
| Also worth knowing | Tax invoices carry the 10-digit business registration number, and local ERP buyers expect Hometax integration (e-tax invoices, cash receipts) and Korean certificate-based authentication. |

You choose: your own cloud account in a region that suits you, or your own servers. Access inside the system is role-based, and during development we work on test or masked data wherever possible. Strict and actively enforced by the PIPC; a February 2026 amendment raised maximum penalty surcharges to 10% of total revenue for serious repeat or large-scale violations and broadened incident-reporting duties.
Yes. Masters, ledgers, stock and opening balances move across and are reconciled with your accountant before cutover, ideally at a year-end or quarter-end.
Yes. Current language models handle Korean and English well, including mixed-language messages. We still test an agent in each language your customers use before it goes live, and route anything it is unsure about to your team.
Usually one module that fixes the most expensive problem first. For electronics & electricals that is often bOMs with alternate parts and reel, lot & serial tracking. It goes live early, and the rest of the system follows in two-week increments while your team is already using it.
