For Ontario business owners

Know your numbers. Stay tax-ready. Run your business with confidence.

Monthly bookkeeping, tax support and a real person who explains what your numbers mean. So you stop guessing and start making decisions based on facts.

Request your Coffee & Clarity Call See how it works

Service in English and Spanish. Servicio en español.

Within 90 days, you will:

Have clean, up-to-date books every month
Know exactly where you make and lose money
See your cash flow before it becomes a problem
Stop worrying about CRA deadlines and surprises

You did not start a business to do bookkeeping

But here you are. Sorting receipts at night. Wondering if you can afford to hire. Bracing for tax season. Not sure if the business is really making money, or just busy.

You are not bad with numbers. You have just outgrown doing it yourself.

Who we work with

Established, incorporated Ontario businesses, usually with $250K or more in revenue, that need more than a once-a-year cleanup.

Construction and trades

Real estate investors

Restaurants

Consultants and service businesses

Most bookkeepers send you reports. We explain what they mean.

Three parts, every month, working together.

1

Monthly bookkeeping

Your books, done accurately and on time every month in QuickBooks Online. No more year-end scramble.

2

Tax guidance

HST, payroll and corporate tax handled with you, not after the fact. You know what is coming before CRA does.

3

Clarity meetings

We sit down together, walk through your numbers in plain language, and talk about what to do next.

What changes for you

Freedom to grow

Hire, invest and take that vacation based on facts, not guesses. Stop living in reactive mode.

Peace of mind

Your books are organized, accurate and current. Nothing is being missed, and tax season stops being scary.

More money kept

Better cash flow, smarter tax planning, and fewer costly penalties and interest charges from CRA.

Your evenings back

No more weekends spent chasing receipts. More time for your clients, your team and your family.

Your first 90 days

A clear path from overwhelmed to in control.

Month 1

Control

We get your books clean and current, set up a simple monthly routine, and flag any CRA deadlines or risks.

Month 2

Clarity

Your first clarity meeting. We walk through your profit, cash flow and taxes so you know exactly where you stand.

Month 3

Confidence

You make decisions with real numbers: pricing, hiring, spending and planning for tax. Then we keep it going every month.

Choose your level of support

Simple monthly pricing. No surprise invoices.

Dayani Castro, founder of D. Castro

Hi, I'm Dayani

I founded D. Castro to give Ontario business owners what most of them never get from a bookkeeper: someone who explains the numbers and helps them decide what to do next.

My team and I handle the bookkeeping, payroll and tax work. You get calm, clarity and the confidence to focus on growing your business.

We work in English and Spanish.

Common questions

My books are a mess. Can you still help?

Yes. Most new clients start there. We do a one-time cleanup first so your monthly numbers are accurate from day one.

Do I have to switch software?

We work in QuickBooks Online. If you use something else, we will move you over as part of getting started.

What happens on the Coffee & Clarity Call?

It is free and there is no pressure. We look at where you are, what is worrying you, and whether we are a good fit.

¿Trabajan en español?

Sí. Puedes trabajar con nosotros completamente en español.
