Zeimee is a monthly accounting AI agent for tax accounting firms and accounting practices, developed by Zeimee Inc. (incorporated under the name Vibe Coding Lab Inc.). It takes transaction records from your accounting software plus supporting documents arriving by file, LINE, or email (invoices, receipts, and so on), and has AI generate candidates for journal entries, document linking, and reconciliation — all gathered into a single review screen. Candidates produced by the AI are never registered directly into the accounting software: the design requires a staff member to review, edit, reject, or approve each one before it is reflected. It supports freee Accounting and Money Forward Cloud Accounting. Early access began in May 2026, and by August full-scale adoption was underway at Seiwa Tax Corporation (Hiroshima Prefecture), a firm with over 2,000 client companies — one sign of how validation in real practice is spreading. For that validation, the development team spent a full month embedded on-site at a tax firm, building features around how the staff actually work — the kind of patient, hands-on customer development that doesn’t scale easily.
Key Features
- AI journal entries: Proposes account and tax classification candidates based on bank and card statements
- AI document analysis: Reads invoices, receipts, and other supporting documents, then creates candidate links to transactions
- AI reconciliation: Matches billing against incoming and outgoing payments, organizing discrepancies for review
- Monthly checks: Automatically checks balances, anomalies, and missing documents
- Client communication: Organizes candidate lists of missing documents and open questions, supporting decisions about what to request from clients
- Task management: Tracks progress and outstanding items per client in a single list
Note that expanded accounting-software integrations, a client portal, automatic reminders, monthly report output, per-staff KPIs, and AI check-rule management are listed on the official site as features planned for future release.
Pricing
The official site (zeimee.com) has no pricing page; pricing is handled through individual quotes and inquiries. According to Nikkei reporting as of August 2026, there are three plans tiered by client-base size, at levels reported to run from just under ¥40,000 to a bit over ¥130,000 per month, with firms handling 81 or more clients moving to a fully custom quote. That said, official plan names and the criteria for each size tier aren’t publicly confirmed, so if you’re considering adoption, it’s best to inquire directly through the official site.
Pros and Cons
✅ Pros
- Consolidates journal entry, document analysis, and reconciliation candidates into one review screen, cutting down on switching between multiple tools
- AI output isn’t registered as-is — staff can review, edit, reject, or approve, which limits the risk of incorrect entries
- Supports major accounting software including freee Accounting and Money Forward Cloud Accounting
- Has a real adoption track record, including full-scale validation at a tax corporation with over 2,000 clients (Seiwa Tax Corporation)
⚠️ Cons
- Supported accounting software centers on freee Accounting and Money Forward Cloud Accounting; others such as Miroku Joho Service (MJS) remain at the validation stage
- No price list on the official site — pricing runs through inquiries and custom quotes
- A very new service, incorporated in March 2026 with early access starting that May, so both track record and feature set are still developing
- Assumes the firm handles operations; the document-submission flow from clients themselves still needs to be set up separately

Zeimee differs from freee’s own AI agent platform for tax and accounting firms, “freee Agent Hub,” and from “freee-MCP,” the MCP server for operating freee’s core functions. Its position is to span freee Accounting and Money Forward Cloud Accounting, consolidating journal entry, document, and reconciliation review into a single screen.
Who It’s For
- People at tax firms and accounting practices with many clients who want to streamline the monthly work of bookkeeping, document verification, and reconciliation
- Firms that want to standardize bookkeeping work where judgment varies by staff member, and level out processing quality across offices
- Firms that want to serve more clients with limited headcount while holding down hiring and training costs
- Accounting firms interested in generative AI but unsure how to fold it into actual workflows
Summary
Zeimee is a monthly accounting AI agent that streamlines bookkeeping, document verification, and reconciliation at tax and accounting firms through a division of labor: AI drafts the candidates, staff approve them. Though very new — incorporated in March 2026 with early access starting that May — validation in real practice is steadily advancing, including full-scale adoption at a tax corporation with over 2,000 clients and a runner-up finish at “JAFCO SEED Pitch 2026,” a startup business-plan competition. Pricing is undisclosed and quote-based, which is a real constraint, but for tax firms looking to bring bookkeeping, documents, and reconciliation together into one review screen, it’s worth reaching out to confirm the specifics.
