Building a startup is hard enough — your finance stack shouldn’t slow you down. Whether you're still validating your idea or already raising your seed round, having the right finance tools in place from day one can save you hours of pain (and thousands of dollars) later.
In this post, we’ll walk you through how to build a modern, scalable finance stack — starting with just the essentials and layering in tools as your startup grows. Best tools for startup finance stack to scale
Why Your Finance Stack Matters (Even Early On)
When founders hear “finance stack,” they often think it’s something they’ll need later — once there's a CFO or revenue or investors. But the earlier you put the right systems in place, the easier it is to:
✅ Track your burn and runway
✅ Stay investor-ready at all times
✅ Avoid costly tax and compliance mistakes
✅ Scale your ops without financial bottlenecks
A modern finance stack should be lean, automated, and modular — able to grow with your company without forcing you into expensive legacy systems.
The Core Stack: What Every Startup Needs
At a minimum, here’s what your initial setup should include:
1. Xero – Your Accounting Hub
Think of Xero as your financial command center. It’s where all your numbers come together: revenue, expenses, payroll, taxes, and more.
Why Xero?
Built for small businesses and startups
Bank feeds = no manual data entry
Clean interface, easy to use (even if you're not a numbers person)
Scales well as your needs evolve
👀 Pro Tip: Set up your chart of accounts properly from the start so you can track burn, cost centers, and funding sources.
2. Dext – Your Expense Manager
Dext makes it dead simple to manage receipts, invoices, and bills — all from your phone.
Why Dext?
Snap a photo of any receipt, and it auto-syncs to Xero
Extracts data using OCR, reducing manual entry errors
Helps you stay audit- and tax-ready
📦 Use Dext to build a clean paper trail. No more chasing receipts at tax time.
3. Payroll – Paying Yourself & Your Team
Startups often make the mistake of treating payroll as an afterthought. But paying yourself properly (salary vs. dividends), issuing T4s, and staying compliant with CRA matters more than you think.
Recommended Tools:
Wagepoint – Friendly for Canadian small businesses
Deel or Remote – For distributed/global teams
Payworks – If you're scaling a Canadian in-house team
💡 Ask your accountant to help you set up tax-efficient owner compensation from day one.
The Next Layer: As You Grow
Once you’re generating revenue or have external funding, it’s time to layer in the next level of tools.
4. Cash Flow & Forecasting Tools
No founder should be flying blind on cash. As you scale, forecasting becomes mission-critical.
Tools We Like:
Float – Real-time cash flow forecasting that connects to Xero
Fathom – Visual reports and KPIs for investor updates
LivePlan – Great for business planning + budgets
📈 Set up monthly dashboards to track actuals vs forecasts — it’s what smart founders do.
5. Integrations That Save You Time
The magic of modern tools is in how they connect. Don’t make your stack harder than it needs to be — automate wherever possible.
Smart Integrations:
Stripe or Shopify → Xero (via native or tools like A2X)
Gusto or Wagepoint → Xero for payroll
Dext → Xero for expenses
Hubdoc or Google Drive → Cloud storage for receipts
Zapier → Automate finance workflows
🛠️ Build your stack around Xero as the hub, and everything else will fall into place.
A Sample Stack at Different Stages
Stage | Tools |
Pre-Seed | Xero, Dext, Wagepoint |
Seed | Add Float (cash flow), basic payroll, reporting dashboards |
Series A+ | Layer in Fathom, Gusto/Deel, bill pay automation, controller/CFO support |
Final Thoughts: Keep It Lean, But Don’t Wait
Your future self (and your investors) will thank you for getting this right early. A messy back office can derail a deal, waste your team's time, and cost you credibility. But with the right tools, your finance stack can become a growth enabler instead of a drag.
