01
You stay in charge
You own the system. We build it, hand over the code and the credentials, and step out. No subscription that suddenly gets more expensive once you are dependent.
Bookkeeping that
runs itself.
You started the business to do what you are good at. Not to photograph receipts on Sunday evening, guess VAT codes, and pay for systems that still send you a monthly invoice.
Built to stop costing after delivery.
The big bookkeeping platforms live on monthly fees. We do the opposite. You pay once, you own the system, and we are out. No lock-in, no price hikes, no vendor panic.
02
Built for how small businesses actually work
No accounting consultant required for daily use. We set it up, we explain it in plain language, you use it. Works for a consultant with 30 receipts a month as well as a small company with 300.
03
Pay once, own it
Project deliveries are the default. Fixed price, working system, no monthly fees. Optional support if you want it. You can walk away whenever.
04
SIE export and BAS accounts
Standard formats your accountant already knows. Everything is exportable, everything is auditable, no one needs to learn new software. Built on the BAS chart of accounts, not on a black box.
Three steps. No surprises.
From first email to a finished system. No subscription, no vendor lock, no thirty page proposal. You see the whole road before you step on it.
01
We talk for 30 minutes.
Tell us what eats your time around bookkeeping. We listen, we ask, and you get a written answer with three things we would change first.
02
We build it in 14 to 30 days.
Mostly hands off for you. We check in twice along the way so nothing goes in a direction you did not ask for.
03
You own it.
No subscription. We hand over the keys, the code and a short walkthrough. Optional support if you want it.
Four results we are building toward. No tech jargon.
These are the results we are building the system for. SiffrAI is in a pilot phase during 2026 and none of this is in operation at any customer yet.
Receipts in the picture, booked in 30 seconds.
Take the photo, type the amount if it is hidden, done. Account, VAT and supporting docs are filled in by the AI. You verify. No Excel, no folder of 200 papers in January.
VAT returns that prepare themselves.
The period's data is gathered and reconciled continuously. When the deadline comes, you press a button. No panic the day before, no retroactive hunt for invoices.
Reminders to late customers without lifting a finger.
Due dates are tracked. Friendly reminder on the day. Firm reminder after seven days. Collections notice after thirty. You get the alert when someone actually pays, not when you have to nag.
Year end without three days of evening work.
Accruals, depreciations and reconciliations happen continuously. By year end, 80 percent is already done. You and the accountant spend time on what actually requires you, not on hunting receipts.
Real work, real numbers.
We only talk about clients who let us put their name on a page. SiffrAI is in pilot during 2026. The first company's case will appear here once it is in production.
The first pilot company
We are looking for a Swedish sole trader or small company tired of their current solution, or the latest price hike, willing to test the concept with us at cost. In exchange for a documented case afterwards.
Frequently asked questions
Does SiffrAI keep the books in line with the Swedish Bookkeeping Act for a sole trader?
SiffrAI is an AI-assisted bookkeeping system that Wilhelmsson Labs builds for sole traders and small companies in Sweden. It is in a pilot phase during 2026. Under the Swedish Bookkeeping Act (1999:1078) the company is always the one responsible for its books, regardless of the tool used. The AI suggests the posting and you review and approve every voucher.
How does AI bookkeeping work for a sole trader?
With SiffrAI you will be able to photograph a receipt, and the AI then reads the amount, date, supplier and VAT rate and suggests a posting that you approve before anything is booked. Invoices are handled the same way. You own the system. We are currently looking for the first pilot company.
Can AI suggest the right BAS account for receipts in a sole trader business?
Yes, SiffrAI is being built to suggest a BAS account based on your chart of accounts and earlier bookkeeping, but you always review and approve the suggestion. If a receipt lacks a VAT breakdown, the system is meant to flag it.
What does SiffrAI cost for a sole trader?
SiffrAI costs SEK 19,000 as a one-time fee plus SEK 590 per month for operation, support and updates in Tier A, where we run the system. In Tier B the system is installed on your own server for a one-time fee of SEK 39,000 plus about SEK 100 per month in server costs to the server provider. The one-time prices include VAT. Tier C and all terms are on siffrai.se/priser.
Does SiffrAI replace bookkeeping software such as Fortnox or Bokio?
Yes, SiffrAI is meant to be your own bookkeeping system that you own, instead of a subscription. Existing history can be imported as a SIE 4 file, and all bookkeeping can be exported as SIE 4 at any time if you want to switch software.
Is SiffrAI only for sole traders, or also for small companies?
SiffrAI is built for both sole traders and small companies, and the same system is offered in a tier for consultancies with several clients. That tier, Tier C, includes iXBRL export of annual reports to the Swedish Companies Registration Office.
