Our verdict on SmartBill
SmartBill is a Korean electronic tax invoice service for businesses that issue and manage sales and purchase records. It covers creating, issuing, amending, and viewing invoices, with mobile issuance and lookup alongside its web service. Its scope is particularly relevant to Korean businesses that need tax-invoice workflows connected to the National Tax Service, rather than companies seeking a general-purpose invoicing tool for multiple regions.
Workflow depth is a defining part of the product. Businesses can use bulk invoice workflows and CSV upload, request reverse-issued invoices, and transmit invoices to Korea’s National Tax Service before looking up transmission results. The API supports issuance for taxable, zero-rated, exempt, and consignment invoices, plus invoice status lookup. ERP systems are the stated integration fit. This makes SmartBill more suitable for teams coordinating invoice processing with existing records or systems than for businesses that only need occasional single-invoice creation.
Pricing is usage-based, with postpaid and prepaid options. The published plans show a starting price of KRW 11,000 for 50 invoices; postpaid charges KRW 220 for each invoice beyond the included monthly allowance, while prepaid balance decreases by KRW 1,100 per invoice. Rates include VAT, and the prepaid figure reflects the smallest displayed package. API integration and on-premise deployment are custom quoted. Phone support and documentation are available, but support is not listed as 24/7. Choose SmartBill for Korean tax-invoice compliance workflows and API or bulk processing; businesses needing broader geographic or invoice-format coverage should consider alternatives.
