When Your Bank Becomes Your Accountant

Why pay exorbitant accounting fees when the dataโ€™s already right there on your bank statements? This local startupโ€™s unlocking Xero-style bank integration at 1/3 the priceโ€ฆ

Few companies start big. Most of SAโ€™s 3 million MSMEs are scaling hobbies or founders just testing an idea (too early to formalise). So most begin as a sole proprietor, trading in their own name (often using their own bank accounts).ย 

The problem is that when the business starts working, founders get busy and then things move fast. And thatโ€™s when accounting and bookkeeping often get left behind.

But itโ€™s important to formalise

Thing is, you need good bookkeeping to apply for funding, access loans and financial tools, register for VAT once you hit R1mil in annual revenue, etc. Not to mention knowing how your business is doing is obviously super important as a founder.

In fact, research shows that nearly half of a small businessโ€™s chances of survival come down to how well it manages its finances. Which was an important problem to solveโ€ฆ

The opportunity at the early stage

Anyone whoโ€™s ever used an accountant will tell you the hardest part of the job is just reconciling all the lines on bank statements โ€“ sorting what withdrawals/deposits are for the business and which are personal.

Itโ€™s not new information; your bank already has it, which is what many cloud accounting software packages offer โ€“ direct bank integration, to make recons easier for accountants.

The only problem? Entry-level packages are quite expensive, and in most cases, the software is built for accountants, not entrepreneurs. Leaving room for a founder-focused, more affordable South African playerโ€ฆ

The local startup making your bank your accountant

stub is a cloud-based accounting package thatโ€™s built with founders as the primary user in mind: integrating with your bank accounts (just like Xero), but with a much simpler setup and interface, free tier and the full package at just 33% of the price (R150 gets you all set!).

It helps you auto-categorise transactions, making bookkeeping a breeze even for founders who want to stay hands-on with their business finances (instead of leaving it all to an accountant). Not to mention it integrates with local tools entrepreneurs already use.ย 

A recent Capitec tie-up hooks up transactions directly from a business owner using their personal account (with business accounts on the way), meeting small businesses where they actually bank.ย 

We chatted to stub Co-founder Tayla Dandridge, who told us stub's API makes it easier to integrate with more tools and that the stub team also likes building what their users need, so if youโ€™ve got a tool you like working with and would like stub to integrate with it, theyโ€™re open to chatting.ย ย 

With more and more local tools being built for how South Africans actually run our businesses, the global players might just have some stiff competition on their hands.

UP OR DOWN?

A graph that matters

SAโ€™s biggest data centres show the coming crunch in AI-era power demand.

Via The Outlier

South Africa has 56 data centres with a combined 350MW load, and 10 of them now account for nearly 80% of it:

๐Ÿ’ก Teraco dominates with the top three spots, including its Isando campus at 70MW and 32'000mยฒ, making it the largest in the country.

๐Ÿ’ก These top 10 centres alone represent 278MW of load capacity, showing how quickly demand has concentrated at the top.

๐Ÿ’ก Only five centres are currently AI-capable, meaning South Africa holds just 1% of global AI data centre capacity, compared to the US, which hosts over 40%.

As demand surges (especially from power-hungry AI workloads), operators are already moving upstream. Teraco, for instance, is building a 120MW solar facility in the Free State to secure future energy.

AROUND THE WEB

Bored? Give these a spinโ€ฆ

๐ŸŽฌ Tool to Try: Sora Watermark Remover erases text overlays and logos from videos.

๐Ÿฆฃ Thatโ€™s Interesting: A small group of woolly mammoths were still alive long after the pyramids were built.

๐Ÿ”ง Hack: You can locate an annoying rattle in your car without driving by using a tone generator app.
