The self-driving accounting practice
Numira pulls the data, reconciles the books, files the returns and surfaces the advisory across every client, then gets smarter with every correction. Eighteen autonomous agents and an AI voice team, on EU/NL-sovereign infrastructure.

The platform
Most software hands you another dashboard to check. Numira does the work, spanning the entire workflow, from pulling a ledger to filing a return to flagging the risk before it bites. Three capability layers, every one autonomous.
Run the practice
Numira connects to your clients' books and handles the routine: pulling ledgers, reconciling banks, reading documents, and chasing what's missing before you notice it's late.
File everything
From BTW to the annual accounts to the Vpb return, Numira prepares it, cross-validates it, and routes it straight through the Belastingdienst (SBR via Digipoort) and the KvK, with a human approval gate before anything is submitted.
Advise proactively
The work that wins fees but never gets time. Numira watches every client for distress, forecasts their cash, models their tax, and benchmarks them against the book, surfaced before the client asks.
Watch it run
This is the actual pipeline: the named agents, the models each task routes to, and the one gate that is always human. Follow a single client’s month through it.
Receipts photographed at a kitchen table, PDFs from suppliers, a till CSV. OCR reads every line; duplicates are fingerprinted and caught at the door.
Model router · right brain, right task
Audit trail · every decision logged
23:41 · intake: 14 docs parsed, 2 rejected as duplicates
The model router sends each task to the lightest model that can do it: learned rules and on-box models first, Claude Haiku for routine classification, Sonnet for document reasoning, Opus for judgment calls. Your AI bill stays proportionate to the work.
An illustrative run with representative figures, but every agent, model route and approval gate shown here is the shipped system, not a storyboard.

The engine
Numira isn't a dashboard you check. It's a roster of autonomous agents that run on a schedule and react the instant data changes. Each one runs the same loop, logs every decision with its reasoning, and learns from your corrections.
01
Watches data freshness, spots missing documents, chases automatically.
02
Tracks every BTW, loonaangifte, Vpb and KvK-SBR deadline under the uitstelregeling, and plans escalation.
03
Reconciliation anomalies and P&L trend analysis across the book.
04
Pre-checks returns, checks verlegging, ICP and KOR, and catches suppletie cases.
05
Ages invoices, chases payment, drives lock-up days down.
06
Verifies Numira and the client ledger stay in sync, both ways.
07
Assembles BTW, Vpb and the jaarrekening as SBR and files them through Digipoort to the Belastingdienst and KvK, then reconciles the receipt.
…and eleven more: payroll, onboarding, document chase, audit trail, Belastingdienst correspondence, working papers, property and trust. The full roster ships on every tier.
The moat · smarter every day
Numira doesn't just do the work. It watches how you work. Every correction, every preference, every client quirk becomes a permanent rule. The result is a system shaped entirely around your practice: the longer it runs, the further ahead it gets, and the harder it is for anyone to replace.
The compounding edge
The flywheel
You correct it once
A category, a BTW treatment, a tone of voice, flagged in a click.
It writes a rule
After two identical corrections the rule is locked in, with your reasoning attached.
It never asks again
The rule is consulted before every future decision, for every client.
Your edge compounds
Two years in, you’re running a system no competitor can buy off the shelf.
What no one else can give you
Agents observe, plan, act and learn, logging every decision with its reasoning and confidence. Not a chatbot bolted on.
Every correction becomes a permanent rule. Numira learns your house style and each client’s patterns, and locks it in. Your edge compounds the longer it runs.
A natural-voice receptionist answers, triages and routes client calls, then briefs partners with a Monday-morning replay.
One isolated, encrypted, firm-branded instance per firm. A signed licence and bytecode-only build, so your data never mingles.
While you sleep
While the office is dark, the agents work the books: reconciling, chasing, reading documents, filing, watching for risk. You walk in to a Monday-morning brief, not a backlog.

The Numira Fleet Cortex
Each Numira instance learns your firm privately: your rules, your tone, your clients. Opt in to the Fleet Cortex and the anonymised lessons travel: a categorisation pattern proven at one firm, a BTW edge case caught at another, benchmarks drawn from the whole fleet. Every firm that joins makes every agent sharper.
Opt-in, firm by firm
Fleet learning is off until you switch it on. Leave any time; your firm’s private rules stay yours either way.
Rules travel. Data never does.
What’s shared is the anonymised pattern: a rule, a threshold, a benchmark. Never a client name, a transaction or a record. Your numbers never leave your instance.
Compounding for everyone
A correction made at one practice becomes a candidate rule for the fleet, reviewed, anonymised and distributed. The agents get smarter every month, everywhere, at once.

Integrations
Numira sits on top of the client's existing ledger, so nobody has to switch software. It pulls trial balances, bank transactions and invoices on demand, then pushes back draft bills, categorisations and journals, with drift detection that keeps both sides honest. Beyond the ledger it plugs into the tools your firm already lives in, from Teams and Gmail for approvals and chasers to Zoom for meeting notes.

The frontier · 2026–2027
Numira ships on a roadmap sequenced in waves, each compounding the last. This is where it stops being software you operate and becomes capability that operates for you, and why the lead only widens.
Conversational AI
Ask Numira anything about a client’s numbers, in plain English or by voice. Plain-language accounts, a live tax-scenario simulator and verified self-service put answers in clients’ hands, 24/7.
Real-time assurance
Every transaction reviewed the moment it lands, exceptions surfaced for partner attention, live what-if modelling. The point where Numira becomes staff, structurally impossible for SaaS rivals to match.
Your judgment, scaled
An AI trained on your senior partner’s historical decisions: reviewing working papers by vision, narrating the year-end in your firm’s own voice, and applying your house style everywhere.
It drives the tools
Numira navigates the Belastingdienst, KvK, Digipoort, Exact and Twinfield itself (filing BTW, Vpb and the jaarrekening as SBR, and depositing accounts at the KvK), doing the clicking your team does today, on your behalf.
Why now
AI has crossed from novelty into genuine capability, and Numira is built by AI engineers who have pointed that leap squarely at running an accounting practice. It pairs frontier models with a Firm Brain that learns your firm and an opt-in Fleet Cortex where anonymised lessons travel between practices, so every firm that joins makes every agent sharper: a shared, compounding intelligence that legacy practice software cannot retrofit. And because the models Numira owns and tunes keep getting better, for everyone at once, the lead does not just hold; it widens. Sign up now and you are not buying today’s software; you are compounding an advantage.
Trust & security
Handing the grind to software is only worth it if you can trust it with your data and your reputation. Numira is built risk-first: EU/NL-sovereign, isolated, fully auditable, and a human signs off before anything ever reaches a regulator.
Nothing reaches the Belastingdienst or KvK without a partner’s sign-off. Numira prepares and cross-validates; you approve. The autonomy stops at the regulator’s door.
Hosted in the EU/NL: a dedicated VPS on OVHcloud (EU region or an NL datacentre, AVG-compliant, no US CLOUD Act exposure) or an isolated Cloud instance. Never a shared multi-tenant database.
Data is encrypted at rest with a key derived from your RSA-signed licence. No valid licence, no data, and every firm is its own island.
Each deployment learns only from your firm, and your records never leave it. Fleet learning is strictly opt-in and carries anonymised rules: patterns, never data.
Every action, agent or human, is logged with a timestamp and its reasoning. Defensible, inspector-ready, and yours to export.
The deployment ships compiled, with a SHA-256 integrity manifest verified at startup. Hardware-bound licensing, MFA, rate-limited auth throughout.
Why switch
Staff chase documents and key in data by hand.
Agents pull, read and chase, automatically, overnight.
You pay per seat; every hire raises the bill.
Priced per client; every partner and staff member free.
Compliance eats the week; advisory never happens.
Compliance runs itself; advisory is surfaced for you.
Deadlines live in spreadsheets and someone’s memory.
Every deadline watched; a human approves before filing.
Write-offs and lock-up quietly bleed margin.
Under-billing surfaced; debtor days cut.
Software you have to operate.
Capability that operates for you, and learns your firm.
