Hong Kong firm hits 98% accuracy on 36 sets of books

The old software worked. That was the frustrating part.

It worked once someone from IT had set it up. Then a new client arrived, and it needed setting up again. Which fields to read. Where each line should go. All of it written from scratch, with an IT person on the call, and sometimes it still failed and someone had to ask for help.

Monx signs new clients almost every day.

A little bit of everything

Paola Marchisio does a little bit of everything at Monx. That is her phrase. Her title is Global Chief Operating Officer. Her days are accounting.

Monx is an accounting and corporate services firm. Head office in Hong Kong. Offices in Singapore, Thailand, China, Italy, the UK, Dubai and among other countries. The core work is bookkeeping for companies with no accountant of their own. Around it sit company registration, tax, payroll, and work visas.

Two heads of accounting run the books, one national and one international, with a floor of accountants under them. Both heads use Tofu. So do their teams. "We are a big user," Paola says, "because we don't only use it for ourselves but for our clients. Most of our clients."

Was she nervous about AI in the ledger? "No, no, no. Absolutely not." She had used two tools before this one. Both helped. Neither finished the job.

Two tools, two gaps

Her first tool read invoices. It also left fields blank. Every invoice needed a look, and a few fields typed by hand, before it could move to the books. "Faster than doing normal bookkeeping," she says. "But still a little bit time consuming."

The second tool was stronger once it was running. It was also the one with the setup problem. Each new client meant new instructions, written from scratch, with IT on the line. "It was complicated," she says. "Not user friendly."

For a firm that adds clients most days, that is not a software problem. It is a growth tax. Every win at the front door became a project at the back.

Then, last year, Paola met Cristina from Tofu, in Hong Kong.

If you see this, do this

Cristina showed her how Tofu takes instructions. There is no rule builder. There is a place to write a sentence. If you see this, do this.

Paola wrote hers. So did her head of accounting. When a new client comes in now, the accountant on that client writes the notes for that client. No ticket. No IT. "It was a big change for us."

Most days the sentence is not even needed. Tofu learns from what the accountant did last time. "Once Tofu has learned, if you process two or three invoices of the same supplier, it gives you exactly the correct account where you need to book the cost."

We will come back to the accounts. First, the part nobody else asked for.

The sales side

Most firms only need help with bills. Sales invoices come out of the accounting software already made. Monx is different. It bills from a separate system, sends the invoices out as PDFs, and issues a lot of them. So its own sales invoices needed reading too.

Paola made that a condition. She would switch, but the sales side had to work as well as the bills. Tofu at the time was strongest on bills, the harder half of most firms' work. "My case was quite peculiar," she says.

By December, her sales invoices were flowing into Xero. Since then, 1,300 of them have gone through. That is the group's own paperwork. Client books came on top.

Every line to its own account

Now, the accounts.

A Monx invoice might carry accounting, audit, and consulting on one page. In the ledger, each must go to its own revenue line. Accounting fees to accounting sales. Audit to audit. Consulting to consulting. Her earlier tool was less precise on the split, so she checked every line.

Tofu, with a first script Bianca from Tofu's customer team helped write, splits the page. "It's not just the amount and the generic sales account," Paola says. "It's broken down in several accounts, and it's almost never wrong."

That is the moment for her. Not speed. Trust. "It's fast, reliable, and precise. I can trust that the system is really helping me, because I don't have to check as many things as I was checking before."

Upload. Extract. A glance. Approve. "If I upload 100 invoices, it takes me five minutes to upload them all." She expects the glance to go too. "I'm sure I will arrive at a point where I don't even need to look at anything. Just approve and send."

The one that tripped it up

Not everything was perfect on the bills side, and Paola says so. Some Monx bills arrive as a photo of a cheque laid over the invoice it pays. Early on, Tofu read the cheque's date instead of the date underneath. Bianca tuned it, and the cheques now read clean. "It's a very small problem," she says. "Where all the invoices are standard invoices, there are no mistakes."

Accuracy, in her words: "100%? Maybe not. But 98%."

What the team did with the time

No resistance from the accountants. "Everybody was extremely happy." Two or three meetings with Tofu, the head of accounting in the room, and from then on he showed the others.

The time went where time goes in a growing firm. "There are a million other things to do." Her accountants carry more clients each. "Instead of maybe handling 10 or 15 clients, they can do more of their job."

The numbers, checked

Everything above is Paola's account. These figures come from Tofu's own records, pulled on 17 August 2026.

Monx's own Hong Kong books: 1,300 sales invoices and 969 bills posted into Xero through Tofu since November 2025. About 250 documents a month. The sales invoices code out across 13 revenue accounts. One in six splits across more than one account, and the longest runs to eight lines. Two in three of those sales invoices went into Xero with no human edit at all. The rest had a field or an account nudged before approval.

The group and its clients together: 10,000 documents verified in Tofu across 36 sets of books, 5,977 of them posted straight into Xero or QuickBooks. Twenty-two Monx staff use it.

The extra mile

Ask Paola what she would tell a firm that feels the way she did, and she answers with the software first and the people second.

"Among all the software we have been using, it's the best that I have. I don't know if there is something on the market even better than Tofu. But I'm not looking for it."

Then Bianca. "She's not only very quick in answering. She's always going the extra mile. Sometimes she tells me things before I even notice." Last week Paola made a mistake and asked for help. The reply came back: if you are too busy, I can fix it for you.

"For me as a user," she says, "that is a big plus."
