First Month Bookkeeping: Recording Your Initial Transactions
Don’t let the paperwork pile up. We’ll walk you through documenting every dollar that comes in and goes out during your first month.
Why Your First Month Matters
The first 30 days of your business sets the tone for everything that comes next. You’re making equipment purchases, maybe taking on your first client, possibly investing your own money to get things rolling. It’s easy to think “I’ll sort this out later” — but later becomes complicated fast.
Here’s the reality: good bookkeeping isn’t about being perfect. It’s about being consistent. You don’t need fancy software or an accounting degree. You just need a system that actually works for how you operate. And you need to start it now, not three months in when you’re trying to remember which invoice was for that web design project.
Setting Up Your First Transactions
When you open a business bank account, that’s your starting point. Your first entry is simple: the money you’ve put in. If you invested $5,000 of your own funds, that’s your opening balance. Write it down. Date it. This becomes the foundation for everything else.
From there, you’re recording three types of transactions. Money going out — your startup expenses like office supplies, equipment, or that domain registration. Money coming in — your first revenue, whether it’s from a client or a service you delivered. And transfers between accounts if you’ve got more than one. That’s it. You’re not doing anything complicated yet.
The Three Transaction Types
- Expenses: Equipment, supplies, software subscriptions, registration fees
- Revenue: Client payments, service income, product sales
- Owner investment: Your personal money going into the business
Keep Your Receipts and Documentation
This isn’t thrilling advice, but it’s the most important part. Every transaction needs proof. That receipt from the office supply store, the invoice you sent your first client, the bank transfer confirmation when you deposited your startup funds. If the CRA asks about a $200 expense six months from now, you’ll need to show what it was for and when it happened.
You’ve got options here. Some people scan receipts and store them in a folder. Others take photos on their phone and upload them to a cloud service. You don’t need an expensive system — just something consistent. We’ve seen businesses use everything from Google Drive folders to a simple envelope system. The method doesn’t matter. Following through does.
When you record a transaction in your bookkeeping system, reference the receipt or invoice number. If you spent $150 on a laptop, write down which receipt that came from. This takes 10 extra seconds and saves you hours of digging later.
Categorizing Your Transactions
You don’t need a complicated chart of accounts in month one. Keep it simple. Most startups use 8-12 basic categories to start, then expand later when they understand their spending patterns better.
Office & Supplies
Everything for your workspace. Desks, chairs, stationery, office software. The things you use to actually operate day to day.
Equipment & Technology
Computers, servers, tools, machinery. Items you’ll use for multiple years that cost more than regular supplies.
Registration & Licenses
Business registration, domain names, permits. One-time setup costs that get you officially started.
Professional Services
Accounting fees, legal advice, consulting help. Money you pay to other professionals.
Travel & Transportation
Mileage, gas, parking, travel for business purposes. Keep track of the business reason.
Service & Subscription Revenue
Money coming in from clients or customers. Track this separately so you know your actual income.
A Practical Recording Routine
Don’t wait until the end of the month. That’s when details get fuzzy. Instead, spend five minutes every Friday reviewing the week’s transactions. It’s not painful, and you’ll actually remember what each expense was for.
Here’s what that looks like: You’ve got your bank account, you’ve got your receipt pile or your phone photos, you’ve got your spreadsheet or accounting software open. Go through your bank statement for the past week and match it up with your receipts. Date, amount, category, description. That’s one line per transaction. Some weeks you’ll have three transactions. Some weeks you’ll have fifteen. Either way, it takes maybe ten minutes.
Why Friday? Because it’s the end of the week but you’re still in work mode. You haven’t mentally checked out yet. And it keeps everything current. By the time you need your numbers for tax time, everything’s already organized.
Common First-Month Mistakes
We’ve seen enough startups through this phase to know where things usually go sideways.
Not Recording Personal Expenses Separately
That coffee you bought while meeting a client isn’t the same as the coffee you buy for yourself. Keep business and personal spending separate. If you mixed them together, your numbers won’t be accurate when tax time comes.
Forgetting the Receipt
You remember spending $50 on something, but you can’t find the receipt. This happens. Don’t try to recreate it from memory. If you don’t have proof, you might not be able to claim it as a deduction. Be strict about this now.
Waiting Until Month-End to Record Everything
By day 28 of the month, you’ve forgotten what that expense from day 3 was actually for. Small, consistent recording beats one huge session where you’re trying to remember details.
Using Vague Descriptions
Don’t just write “Office” or “Misc.” Write what it actually is. “Desk lamp for workspace” or “Domain registration for company website.” Future you will be grateful.
Tools That Actually Work
You don’t need expensive software in month one. A spreadsheet is completely legitimate. Google Sheets is free, accessible from anywhere, and lets you create formulas that do the math for you. Start there if it’s comfortable.
If you want something with more structure, Wave Accounting is free for Canadian businesses and handles invoicing too. It’ll automatically pull transactions from your bank account once you connect it, which saves time. You’re still doing the categorizing and checking, but the data entry is mostly automatic.
Whatever you pick, the most important thing is that you’ll actually use it. Pick something that doesn’t feel like a burden. If you’re someone who likes spreadsheets, use a spreadsheet. If you like a cleaner interface with fewer options, try Wave. The tool matters way less than the consistency.
Informational Purpose
This guide is for educational purposes and provides general information about bookkeeping practices for new Canadian businesses. It isn’t a substitute for professional accounting or tax advice. Tax regulations vary by province, business structure, and individual circumstances. Consult with a qualified accountant or tax professional to ensure your bookkeeping system meets CRA requirements and your specific business needs.
