Bob & Co Case Study: 1,400 SME Clients, One AI Switch

Xero once tried to buy something from Bob Ng.

He said no.

Not a company. Not a client list. A set of financial-statement templates one of his managers built after hours, in a small Singapore firm most of the industry had never heard of. The software giant his whole practice ran on came asking, checkbook open.

"It was blood and sweat from my managers. I wouldn't let go of it."

To understand the no, you have to understand how Bob Ng builds things.

The secret firm

For six years, his accounting firm was a moonlight job.

Days belonged to his employer. Nights belonged to the company he registered in 2013 and ran from home, one ledger at a time. Accounting is the family trade: his parents ran their own small practice in Malaysia, and when Bob left for Singapore twenty years ago, their firm wound down. The trade didn't.

By 2018, the night job out-earned the day job. That same year, still an employee, he pitched a government-linked company and walked out with the books of twenty companies. One question followed him home: if nights and weekends could win that, what could full attention win?

In 2019 he went to find out.

The clients nobody fights over

You know the clients Bob chose, because they're the ones most firms don't chase. The five-person trading company. The family F&B outfit. The contractor whose shoebox arrives in February.

"I'm an SME myself," he says. "There's not enough respect given to SMEs. They can't pay top dollar. But it doesn't mean they're not contributing to the nation building."

He doesn't pick clients by industry. He picks them by mindset. "If you can improve their bookkeeping from very manual in the first year, and it gets better and better, that's the client you want. We clinch small wins every single year."

Today that philosophy employs about forty-five people across Singapore, Malaysia, Cambodia, and the Philippines serving what Bob puts at 1,400 to 1,500 clients, with a corporate secretarial line so strong that most corp-sec clients hand him their accounting too.

But respect, it turns out, has a math problem. We'll get to it.

The comfortable trap

Bob's firm went cloud before it was fashionable. When COVID emptied every office in Singapore, his was one of the few already built for it. "We really grew during COVID. We were one of the very few using cloud accounting at that point."

Then came the templates Xero wanted, and the no.

Ask him where the streak comes from and he gives you the sentence he runs the firm on:

"If you get too comfortable, things never grow. To move forward, we always have to put ourselves in a position that is always uncomfortable."

He aims that sentence at himself first. He'll admit the firm coasted for a stretch, and that the last six months have been deliberate catch-up: an in-house server now drafts corporate secretarial documents with AI, financial statements are next, and his corp-sec manager Paul, a technology man by background, drives it.

Which brings us back to the math problem.

The forty-cent wall

Bob tried document AI before most firms would touch it. His first tool charged by the scan. Thirty to forty US cents, every page.

Do the arithmetic he had to do. A client paying a small annual fee, sending a year of receipts. At forty cents a scan, serving them with AI meant serving them at a loss. "We couldn't have all our clients using it. We would be making losses. Only the clients with good fees."

Read that again. The tool worked. The math didn't. The clients his whole mission existed for, the small ones, the disrespected ones, were priced out of the automation built for them.

A second tool followed. His review is the quietest execution in software: "Good to have. But we don't lose that much if we don't use it."

And beneath both sat a gap nobody touched: a firm his size runs stacks of Xero Ledger subscriptions, the low-cost plans for small and annual clients, and no automation vendor catered to Ledger at all.

For seven years, the wall held.

"I was totally mind blown"

Then a pricing page from a company called Tofu landed in front of him.

"I was mind blown, man. Totally mind blown. I knew it was going to be a game changer. I told all my managers: literally all the clients, small, large, anything, we could all transition."

Bob has a rule about buying software. "There are only two reasons I buy. Either the salesperson is amazingly good, or the product is so good I can't resist." He laughs about which one applied.

Then the vendor did something vendors had never done for him: they built for him. His Xero Ledger problem became Tofu's manual journal feature and pre-coded templates. "Tofu is probably the only software right now that caters for Ledger subscriptions. It's a game changer for us."

The clients nobody could afford to serve properly now pay for themselves. The math finally matches the mission.

The logic, for the skeptics

Sixty-nine client companies live. Close to three thousand documents processed in July alone, and climbing. Four document types running: bills, sales invoices, expenses, bank statements. The whole team on it, down to the ten-person Cambodia office, where, Bob says, "when we show them data entry can be done just by scanning, people are mind blown."

Against 1,400-plus clients, the migration has barely begun. "Eventually, we will move everyone into it."

What a firm does with its hands free

The next uncomfortable position is already chosen. A Malaysia subsidiary, months old, taking a decade of Singapore lessons to a market of thirty-three million. A joint venture building corp-sec software to Bob's own specification. And a target that reverses his oldest habit: after years of hiring four to six people annually just to grow, he wants the next thirty to fifty percent of growth on the same headcount. Technology carries the difference. People carry the judgment.

Would he recommend Tofu? "One hundred percent. To anyone willing to take the first step in changing how they do data entry."

His parting words to the team building it: "Please continue doing whatever you guys are doing. I do believe you guys can change the industry."

Some things Bob Ng won't sell. Comfort is one. His managers' templates are another.

The hours his people spent typing? Those, he was glad to lose.
