Your first 90 days in business: A guide for new owners

Starting a business comes with an ever-growing to-do list — and somehow, everything can feel urgent at once. The first 90 days are a good time to focus on the things that will give your business a solid foundation, from getting your finances organized to finding your first customers.

As your business gets moving, keep an eye on your cash flow, plan for taxes, build a financial cushion and review your progress against your goals. Avoid common pitfalls like mixing personal and business finances, spending money set aside for taxes or focusing on growth. Whether you’re a new sole proprietor, incorporated founder or side-gig operator, here are some steps to consider when you’re ready to take that new business to the next level.

While not everyone can (or should) take the exact same approach, this guide can help you get organized, stay focused and understand what you need to kickstart real progress — instead of playing whack-a-mole with urgent must-dos and surprises.

Before you formalize the business: take stock of where you are

Before you jump into a plan, you’ll need to have the basic building blocks in place. Here’s a list of the first steps you need to cover before you can kick things into motion.

• A business idea: Have a concrete concept.

• A basic budget: Have at least a general sense of start-up costs and monthly expenses, plus how much time you’ll need to commit.

• Documents and paperwork: You may need government ID and other information to register or incorporate your business, open a business bank account and register for GST/HST or other sales taxes, depending on your situation and location.

• A way to organize business finances: Know how you’ll keep business money separate from your personal finances from day one.

Days 1 to 30: Build the foundation

Now it’s time to get serious. The first few weeks can feel like a lot. There’s paperwork to tackle, customers to find and plenty of decisions to make. You don't need everything figured out on day one. Focus on getting the basics in place, then build from there.

Set your 90-day goals

Create a business plan one-pager that concisely but clearly outlines the basics: what you’re selling, who (and where) your customers are, plus some measurable targets for the quarter, such as revenue, units sold, number of customers or another product-related milestone.

Choose a business structure

Essentially, this means deciding whether to operate as a sole proprietorship or partnership, or incorporate your business. A sole proprietorship is an unincorporated business owned by one person, while a partnership involves two or more people or entities. A corporation is a separate legal entity from its owners. Each structure has different legal, tax and administrative implications, so consider talking with an accountant or lawyer before deciding which is right for you.

Register your business

The specific registration requirements depend on your province or territory and your business structure. The federal and provincial or territorial governments provide resources to help you determine what registrations, tax accounts, permits and licenses you may need. Start by exploring the “Registering your business with the government” page on the Canada Revenue Agency (CRA) website.

Set up bookkeeping and banking

For the former, a basic system (like a spreadsheet) can help you track every dollar that comes in and goes out; you can always upgrade to a paid accounting tool later. For the latter, consider using a dedicated business bank account to keep your business and personal finances separate and make record-keeping easier.

Test your idea with some real clients

A good way to see if your idea has potential is to start with a minimum viable product (MVP) and test whether there's genuine customer interest before investing heavily in the business. This can be as simple as creating a landing page with a “Join Our Waitlist” button, publishing an introductory post on platforms like Substack and speaking directly with potential customers to gauge demand and gather feedback.

Days 31 to 60: Find customers and get paid

To earn revenue, you need customers. That starts with building a brand and brand presence so people can look you up and find you. Once you’ve settled on a business name (which might require registering a trade name), consider creating or setting up:

• A simple logo or visual identity

• A one-page website where people can learn more

• A presence on the social platforms your customers actually use

Remember, the goal is customers and income, not flash and polish. Focus on must-haves, direct outreach and building customer loyalty rather than overspending on branding and marketing before you have the budget for it.

And don't forget about taxes. If your business earns net income, you’ll generally owe income tax on it, so it’s a good idea to start setting money aside early. Consider setting aside money as you go for income tax and sales tax obligations, so you don’t have surprises when payments are due.

Also, if you make taxable sales, you may also need to register for GST/HST. Generally speaking, registration becomes mandatory when taxable supplies exceed $30,000 over four (or fewer) consecutive calendar quarters or in a single calendar quarter (although the rules may be different depending on your situation). If your income is below that threshold, you may be able to register voluntarily. This can allow you to claim input tax credits on eligible business expenses. Check out the CRA’s detailed guidance on GST/HST registration and collection requirements to learn more.

Finally, set aside some time to research whether you need business insurance and how much you would need. Each business is different, so this would be a good time to get a personalized answer from a professional.

Days 61 to 90: Review, buffer and plan ahead

By this point, the excitement of getting started may be competing with a growing to-do list. This is a good time to step back, look at the numbers and see what's working and what’s not.

First, go back to your math. Compare your actual revenue, expenses and cash flow with the goals you set on day one, and decide if you need (or want) to cut any expenses or tweak how you’re managing your cash flow.

Once that’s in place, figure out how you’re going to build a business buffer: think of it as an emergency fund for your business (ideally kept in a separate, interest-bearing account) that helps you cover expenses during slow months or pay for lump-sum costs. This might mean keeping more of the business's cash in the business until you've built up a cushion.

Next, make sure you’re on track for tax season, so filing time is pain-free.

Finally, plan out your next 90 days. Refresh your goals (or set new ones) and decide which tasks you might be able to hand off to someone else — including to a bookkeeper or accountant, who can help you stay on track financially and help you understand your tax obligations and potential deductions.

Common first-90-day mistakes to avoid

As you work on your 90-day plan, keep in mind these common mistakes Canadian business owners make:

1. Mixing personal and business money. Keeping finances separate can make bookkeeping, record-keeping and tax reporting easier. Have a dedicated business bank account and keep things in two channels from the start.

2. Spending your tax money. When you collect GST/HST or other sales taxes, remember that you may have an obligation to remit those amounts to the appropriate tax authority. Be sure to set aside money as you collect it, so you have the cash available when payments are due.

3. Chasing growth before setting foundations. Make sure you've addressed the basics — such as any required registrations, bookkeeping and building a financial cushion — before pushing your business to the next stage.

4. Lack of focus. Trying to attack your list at once often means you get nothing of substance done. Instead, follow a phased plan like outlined above.

Keep your business moving forward

The first 90 days of starting a business can be a whirlwind, but they don’t have to be chaotic. With a smart strategy in place, you can work through your to-do list methodically, no stress needed. From naming, branding and registration to tax planning, keeping your business books in order and opening a dedicated business savings account, your 90-day plan will help you get your business up and running with fewer surprises — and help you be ready for what comes next.
