Sumary

• Running the same month-end close checklist across a firm's bookkeeping clients so accountants only review exceptions and approve
• Preparing VAT returns with every transaction checked against the applicable European VAT rules before the return is filed from the firm's existing tool
• Preparing year-end numbers and working papers before the firm finishes the statutory accounts
• Catching miscodings and wrong VAT treatment during the month and fixing a repeated error across many invoices with one approved draft journal
• Drafting a monthly management pack with commentary for each client from a saved template
• Consolidating a group whose entities run on different ledgers and currencies, with intercompany eliminations proposed

Sumary's pitch is that an accounting firm's bottleneck is preparation, not judgment, and the product is built around that idea. Firm-wide workflows, steps that cannot be skipped, two-approver sign-off and draft-only write-back fit a firm whose partner signs the final numbers. Checking every transaction against country VAT rules, rather than sampling, matters most to European practices with large VAT client books. The other finance agents listed here mostly target one company's in-house team or US audit work; Sumary instead targets bookkeeping and compliance preparation across many clients on Xero, QuickBooks and Business Central. The open questions are the usual ones for a young, sales-led product. Pricing, models and documentation are not public. Direct ledger coverage is narrow, and NetSuite is still in beta. The current Workflows product shipped in November 2026, and the time savings come from Sumary's own figures. A firm should pilot it on one standard workflow, such as monthly VAT for a group of Xero clients, and measure review time against its own baseline before rolling it out across the practice.

About Sumary

Sumary is a Copenhagen-based company (Sumary ApS) that sells what it calls an AI operating system for accounting work. The core is Workflows: a firm builds its month-end close, VAT and year-end workflows once, from the checklists and working papers it already uses, and pushes them to every team and client, with local changes where a client needs them. Scheduled agents then run each step daily, weekly, monthly or yearly: payroll journals, the AP sub-ledger tie-out, accruals, prepayments, deferred income, depreciation and bank matching. Each task comes back done or waiting for review. When an agent is unsure it asks the accountant and reuses the answer the next month, and a firm's methods can be saved as named skills. Control is the main design constraint. A month stays open until every required step has run and been approved, with up to two approvers per task. Nothing is written to a ledger without approval, approved journals arrive in the ledger as drafts, and every agent action is logged. Around the workflows sit three other modules. Anomaly detection checks every transaction against VAT rules (Sumary says the rules for every European country and US sales tax are built in as decision trees), the client's own coding history, supplier contracts and the firm's own rules, and drafts a correction for each flag. Reporting builds management and board packs from a prompt and consolidates groups across different ledgers and currencies. The AI CFO assistant answers questions about a client's numbers with the transactions behind each answer, and can be reached from Claude, ChatGPT or Copilot through an MCP server. What sets Sumary apart from in-house close tools is the multi-client model: one standard applied across a firm's whole client base, client-versus-client benchmarking, and VAT checking built for European practices. Firms get forward deployed accountants who sit in on the first closes. Sumary does not replace the final step: it prepares the numbers and working papers, and the firm still finishes statutory accounts and files from its existing tools. The tradeoffs are typical of a young, sales-led product. There is no public pricing, documentation or API. Only four ledgers connect directly, and NetSuite is marked beta. The AI models are not disclosed. Sumary 2.0, which turned close management into general Workflows, shipped on November 9, 2026. Sumary names the Nordics and the UK as its current markets, with Benelux next.
