Second Banana - Bookkeeping & Advisory Hi, I'm Katrien. At Second Banana, I help health professionals and clinic owners with proactive financial support. From bookkeeping to advisory.

Specialized in supporting clinics using QuickBooks and Jane App. Bookkeeper, mom, wife, engineer, and a lover of Tai Chi and rainy days โ˜”

โ€‹After a decade in corporate finance, โ€‹I started Second Banana to give small business owners - the First Bananas - more than just bookkeeping. They get a partner who handles their books, but also looks out for them and actively helps them grow their business. I work 1-on-1 with each client, knowing every detail of their finances and tailoring my support to their specific needs. I provide services in English, French or Dutch. My goal with Second Banana is simple: giving entrepreneurs more time and headspace, knowing their finances are fully handled. I genuinely hope to be the last bookkeeper you'll ever need to hire. If that sounds like what you need, feel free to connect. Let me be your Second Banana.

Your bookkeeper should do more than just record what you give them; they should be looking out for you and your business.

In my latest blog post, I share how a few simple questions saved my client $1700 a year. But more importantly, they gave her the confidence of knowing someone was keeping an eye on her business.

Enjoy the read:

The real value of bookkeeping isn't just recording transactions, it's asking the right questions so you can save your client some money. In this post, I share two simple observations that ended up saving one client about $1'700 a year.

"I'm thinking of incorporating"

It's a sentence I hear frequently from clinic owners.

It sounds simple. Revenue goes up โ†’ I'm growing โ†’ I'm going to incorporate.

But, it's really important to talk to your accountant AND bookkeeper before you move forward. There are a lot of things to consider (new HST account, new QuickBooks account, new bank accounts, possibly new Stripe account, extra monthly costs, new insurance policy, asset rollover, update contract with your subcontractors, ...)

I'm currently writing an article / e-book about what to do and what to know when you incorporate from a sole proprietorship, specifically for therapy, chiro, and wellness clinics.

Stay tuned. Although it can take another while ๐Ÿ˜

(PS. Feel free to share questions you have about this topic.)

Nothing puts me more in my element than a rainy day (no kidding!) and starting the morning with a lovely Google review.

Very grateful for the kind people I get to work with every day! Rain or shine ๐Ÿ˜

How many software subscriptions do you have? ๐Ÿง

I recently wrote a short blogpost on how to avoid paying too much for them.

A simple 20-minutes-per-year check can easily save you lots of money.

Read it here:

Are you paying for software you no longer use? Many business owners have more subscriptions than they realise. This simple 10-minute check helps you spot unused tools, reduce costs, and bring clarity to your finances without giving up what you actually need.

Many clinic owners choose subcontractors because it feels easier than hiring employees.

And it is... if you do it the right way.

I wrote a new blog for coaches, therapists and other clinic owners on how to properly work with subcontractors and avoid stress at tax time.

๐Ÿ‘‰ Read it here:

Hiring subcontractors can be a beautiful thing. For coaches, therapists, and other health professionals running a clinic, subcontractors often mean: โ€ข A VA who keeps things moving โ€ข A marketing specialist โ€ข Another practitioner โ€ข An IT professional โ€ข A bookkeeperIt feels strategic and flex...

If youโ€™re a coach or therapist and your revenue has picked up lately, this is for you.

I often hear, โ€œIโ€™m under 30K this year, so I donโ€™t need to worry about HST.โ€ But the 30K rule is based on four consecutive calendar quarters, not your fiscal year.

If your growth pushes you over the threshold and you donโ€™t register in time, you still owe the CRA the HST from that date, even if you never charged it to your clients.

One 10K month without charging 13% means $1'300 coming ๐—ผ๐˜‚๐˜ ๐—ผ๐—ณ ๐˜†๐—ผ๐˜‚๐—ฟ ๐—ผ๐˜„๐—ป ๐—ฝ๐—ผ๐—ฐ๐—ธ๐—ฒ๐˜, plus possible interest and penalties.

If youโ€™re close to 30K, make sure you understand how the rule works or get proper advice.

Growth is exciting. Tax surprises are not ๐Ÿ˜

We often expect bookkeeping to deliver constant insights and big โ€œahaโ€ moments.

In reality, when itโ€™s done well, it feels boring in the best possible way: calm, predictable, and reliable ๐Ÿง˜โ€โ™‚๏ธ

I wrote a new blog about what that should feel like for business owners who donโ€™t love admin.

Read it here ๐Ÿ‘‡

Good bookkeeping doesnโ€™t create excitement. It creates calm, confidence, and predictable numbers you can trust, without needing to be an admin person.

If youโ€™re a coach or therapist working with subcontractors, make sure to have them invoice you for their sessions.

Some practices only use compensation reports to support the payouts to their subcontractors, but the CRA prefers invoices.

Two reasons:
1. Invoices clearly support the payout expense.
2. They help show that the subcontractor is working as a self-employed and not as an employee.

A small step that keeps your books clean and defensible.
