AI accounting services: we set up AI inside your finance team.

We run our own practice on AI every day, so we know what works, what breaks and what must stay human. We set up the AI, the safety rules and the playbooks in your systems, then train your people to run it.

Two ways to get AI accounting into your business.

Own the system yourself, or let us run it for you. The safety rules are the same.

AI for your own finance team.

You want to keep accounting in-house and make your team faster. We build the same system we run on, inside your company, and hand it over.

See how the setup works

AI-powered accounting, run by us.

You would rather hand over the books. Our accountants run your bookkeeping and month-end close with AI doing the repetitive work, and sign every number.

Books closed by business day 10, guaranteed from month three
Every number checked and signed by a senior accountant
One predictable bill instead of new hires

Bookkeeping and monthly close

What we set up when we bring AI into your accounting.

The tool is the small part. These six things are what make it safe and useful.

The rulebook

One file of numbered rules the AI reads every session: honesty, verification, and what needs approval.

The permission layer

What the AI may read, what always asks first, and what it can never do. Payments and deletions always need a person.

Read-only connections

Links to NetSuite, QuickBooks, Excel and mail. Every connection is listed with what it may and may not do.

Playbooks

Step-by-step procedures for your close and reconciliations. Each step produces one thing you can verify.

The mistake log

Every correction becomes a lesson, and standing lessons become rules. It is the asset most teams skip.

Training

Your people learn to brief the AI, check its work and correct it. No coding needed.

How we set up AI accounting in your finance team.

Small steps. Each one is checked against your own numbers before the next begins.

Week 1Assess
We look at your close and pick the two or three jobs where AI saves the most hours.

One workflow, in your systems, read-only. Results are checked against your own numbers.

Your team runs it. We stay on call and review the mistake log with you.

AI accounting safety: the four rules our AI never breaks.

These come from running AI on real books every day. Every one of them exists because something once went wrong.

AI safety check

Read-only accessThe AI reads your systems. It never sees a password and cannot move money or post to your ledger.
The human keeps the last clickSubmit, send, pay, post, upload. A person does it, and the review happens there.
A block ends the turnIf any control says no, the AI stops and reports. It does not try again another way.
Missing input stops the stepNo placeholders and no invented numbers. A finished-looking job with a hole is worse than no job.

AI accounting results from our own engagements.

106 of 106invoices matched to the penny against a customer's own records, proving billing was never the problem.

~$23Kin checks that never arrived, traced to a wrong mailing address. 19 checks reissued with zero disputes.

~$93Kmissing from a bank import that silently dropped 7 rows. Our process caught it, and the check became a written rule.

Real engagements, anonymised. Figures are rounded.

Hundred MS elevated our month-end close game by implementing AI into all our financial operations, super seamlessly. I was skeptical in the beginning. Now we have a faster close, cleaner books and schedules. Super happy about that.

Hundred brought significant accuracy and stability to our internal accounting processes, and I trust them very much.

Accountants who run on AI every day, with a technology adviser beside them.

We are not an AI vendor. We are a finance team that had to make AI safe enough for our own clients' books first. You get that system, with the scars already in it.

AI accounting services: questions, answered honestly.

1Is my data safe with an AI doing the work?

Yes. The AI works inside your own systems with read-only access. It never sees a password: a person logs in, the AI reads. It cannot move money, post to your ledger or send anything outside. Every sensitive step needs a human.

2Does the AI make mistakes?

Sometimes, like any tool. That is why nothing ships on the AI's word alone. Every number must tie to a source document, every schedule must reconcile to the live ledger, and a person checks the result. When something slips through, it becomes a written rule so it does not happen twice.

3Will AI replace our accountants?

No. It replaces hours, not people. The mechanical work (pulling data, matching, tying out, drafting) goes to the AI. Judgment, policy and accountability stay with your people, who move from doing the work to reviewing it.

4Which AI tools do you use?

Mainly Claude from Anthropic, and OpenAI models where they fit better. The tools will change. The rulebook, the permissions and the playbooks are what stay, and they belong to you.

5Do we need NetSuite for this?

No. We set it up around the system you already have: NetSuite, QuickBooks Online, Sage or Excel.

6What does it cost?

The price depends on your systems and volume. You can work with us on a project, monthly or hourly, and the discovery call ends with a written scope and quote within two days.
