Please Code Your Expenses to the Department Level | SaaS Metrics School | SaaS Coding
Greetings, SaaS founders! Ben Murray here, bringing you another crucial lesson from SaaS Metrics School. In this episode, I tackle one of the most foundational yet often overlooked aspects of SaaS financial management – coding expenses to the department level.
Whether you're just starting out or scaling your SaaS company, this is a Day One exercise that will save you countless hours of frustration and prevent costly mistakes down the road. Proper expense coding lays the groundwork for understanding your gross profit, COGS (Cost of Goods Sold), and operational expenses (OPEX). It helps you answer critical questions like:
How much are we spending on R&D, Sales, Marketing, and G&A?
Are we over-invested or under-invested in key areas?
Where are we burning cash, and where should we make adjustments?
Having poorly organized financials is a challenge I see all too often with the SaaS companies I work with. Many founders think that since they are just starting out, it’s not necessary to code expenses to the department level. But the reality is that this is exactly when you should start! From the first day of your SaaS journey, every contractor, employee, and vendor should be coded according to their department – whether they’re working on R&D, Sales, Marketing, or General & Administrative (G&A) tasks.
This level of organization will become incredibly valuable when you need to scrutinize your financials, prepare for board meetings, or improve sales and marketing efficiency metrics. Without this structure in place, you'll waste time guessing where the money went, digging through your QuickBooks P&L, Xero P&L, or whatever accounting software you're using. By the time your general ledger is full of expenses, it's much harder to allocate them to the right departments.
So, what's the key takeaway? From day one, work with your bookkeeper to ensure that your accounting software is set up to track spending by department. Code every contractor, employee, and expense to the right department. This might seem like overkill early on, but it’s critical to building a solid financial foundation. Down the road, you’ll thank yourself for setting up this structure, as it will allow you to:
Analyze your spending trends
Improve forecasting accuracy
Understand your company’s financial profile
Make data-driven decisions about where to cut costs or invest more
Feed critical data into your SaaS metrics like sales and marketing efficiency
For a SaaS company, your main departments fall into two categories: Cost of Goods Sold (COGS) and Operating Expenses (OPEX). In COGS, you’ll have departments like Tech Support, Customer Success, DevOps, and Professional Services (if applicable). In OPEX, the main departments include R&D (or Development), Sales, Marketing, and G&A (General & Administrative). G&A covers functions like Finance, Accounting, HR, IT, and Executive roles like CEO, CFO, and Founder.
Why is this so important? Because when your expenses are coded correctly, you can quickly see where you're over-invested, under-invested, or aligned with your financial goals. This leads to better budget management, clearer insights into your profit margins, and more confidence in your numbers when presenting to your board or investors.
To make this process easy, your accounting software (whether it's QuickBooks, Xero, or another tool) should allow you to set up these department codes from the beginning. Work closely with your bookkeeper or accountant to create a system where every expense is tracked by department. This will help you avoid the common pitfall of lumping all expenses into one big bucket, making it impossible to tell where your money is going.
Once your coding system is in place, you’ll be able to analyze important financial data like:
Gross Profit: The revenue left over after COGS
Departmental Investment: How much you’re spending on R&D, Sales, Marketing, G&A, etc.
Cash Runway: Are you at risk of running out of cash? Where can you cut back?
Forecast Accuracy: How much of your spending is aligned with your forecasts?
This structure will also feed into other key SaaS metrics like sales and marketing efficiency, and it will simplify your life when it’s time to close the books each month or prepare financial reports.
So if you want to build a healthy, scalable SaaS business, don’t skip this important step! Start coding your expenses to the department level today, and set your company up for success as you grow. Whether you're using QuickBooks, Xero, or another accounting platform, the key is to get organized early and stay on top of your numbers.
Thanks for watching, and as always, keep building those SaaS metrics foundations strong!
