WEHAGO T (Douzone Bizon) AI features and pricing (October 2026)

WEHAGO T is Douzone Bizon's cloud ERP for Korean tax and accounting firms. It covers bookkeeping, tax filing, payroll and client collaboration, and adds AI bookkeeping, big data client reports and the ONE AI agent.

The base modules cover financial accounting, VAT returns, corporate and personal income tax filing, automatic and manual collection of qualified receipts, bulk submission to the four social insurance agencies, payroll and withholding tax. Around them sit messenger, mail, web office, a client portal (T edge), the employee app NAHAGO, a filing status board fed from Hometax and a workload checklist per client. Douzone Bizon is a Korean ERP and groupware vendor with offices in Seoul and a campus in Chuncheon. Since March 2026 the investment firm EQT has held about 90 percent of its shares; its ONE AI assistant runs on Microsoft Azure.

• Posts receipts automaticallyQualified receipts are collected every midnight or on demand, and AI with big data posts them based on each client's past accounting. Tax firm staff check the result instead of typing every voucher.
• Starts bookkeeping from the trial balanceSpeed bookkeeping begins in the AI trial balance menu rather than in voucher entry. For small clients without special issues, staff can finish the books from a proposed trial balance and adjust only exceptions.
• Writes client business reportsA big data comparison with companies in the same industry produces financial health ratios, detailed analysis and improvement points. Tax firms can hand clients an advisory report without building it by hand.
• Prepares filings proactivelyWEHAGO T AI Edition, launched in April 2026, pre-drafts corporate tax returns for finished clients, generates missing withholding reports and compares payroll with financial statements to flag missing entries. Staff start from a prepared draft.

• Built for Korean tax offices, with Hometax filing status, social insurance bulk submission and client portals in one system.
• The ONE AI agent works with retrieval-augmented generation and function calls inside Douzone's access controls.
• Clients without their own accounting system connect through the free T edge portal and the NAHAGO app.

Douzone Bizon is based in Seoul and Chuncheon. WEHAGO T is built for Korean tax firms and connects to the Hometax portal and the four Korean social insurance agencies.

WEHAGO T only makes sense for firms that prepare Korean tax filings: the interface is Korean and the workflows follow Korean tax and social insurance rules.
