Bookkeeping for Your SaaS Business

A bookkeeper is responsible for keeping accurate and up-to-date information on the financial health of your business.

Although bookkeepers and accountants share some duties, for example preparing tax returns or producing the end of year financial statements, a bookkeeper’s main duty is keeping the basic, daily finances in order.

This is usually accomplished with the double-entry system of accounting discussed below.

Bookkeeping: What not to do

When I first started my online B2B business, my “bookkeeping” consisted of keeping all invoices in a pickle jar along with an apology to my accountant every year.

Not only did this mean a stressful April, but it also meant that I missed valid expenses, had no idea how much money I was spending day to day, and had no actionable data on my company that could be used for strategic planning. Obviously, I don’t recommend this, even if a gherkin is still a great snack.

I was rescued (forcibly) by a banker. They told me bluntly that my “system” of bookkeeping would result in a denial of my bank loan in the short term and the potential for tax trouble in the long term.

Afterall, well-maintained books are the only antidote to a tax audit.

Along with recommendations for bookkeeping software packages available, my favorite advice from them was to take the receipts out of my pickle jar weekly, record all the information into a spreadsheet, write a number on the top of the receipt for easy cross-referencing and then stick the receipt in a photo album as back up.

(Hint: use a code that includes letters indicating the type of expense, the date, and a number starting 0001 for ordering them during the year.)

Of course, there are apps you can use to upload images of your receipts to keep all files digital, but I would discuss this with an accountant before discarding the original receipts.

Before we get into why you need bookkeeping, let’s look at some of the basic terminology used in bookkeeping. Regardless of whether you are thinking about taking a bookkeeping course, pursuing a bookkeeping job, or just want to organize your business, the following are terms that you will encounter regularly and should understand.

Key Bookkeeping Terminology

• Accounts Payable is the account used to track all of the money that you owe to vendors. This is typically a very short-term debt, usually to be paid off within 90 days or less depending on the contract by either longer-term debt (a line of credit) or an asset (cash). A personal example is your credit card: you can pay for a new desk with your credit card today, and then pay it off from your checking account next month.

• Accounts Receivable is conversely the account of all the money that is owed to you by customers. Depending on your billing cycle, whether you use a third-party app to process payments, etc., this is typically money that you can expect to land in your checking account within the next month or two. Accounts receivable of one company are the accounts payable of another. While you record the cost of that desk in your accounts payable, the bank is recording your credit debt in their accounts receivable.

• Assets are everything your company owns. This can be anything from a commercial building to paper clips, from the accounts receivable above to any intellectual property you’ve created. Assets can be purchased with your investments and profits (equity) or loans (liabilities), hence Assets = Liabilities + Equity.

• Balance Sheet: The balance sheet is one of the four main accounting statements, along with the income statement, cash flow statement, and statement of shareholders’ equity. It details the financial situation of your business at a moment in time. The balance sheet helps to show what your business owns and owes, with your assets on the left and the liabilities and equity on the right.

• Capital is all of the company’s assets currently available to invest, spend, etc. It can be used to understand the financial health of your company as more capital helps your company be agile when facing new market conditions.

• Cost of Goods Sold is how much your product costs directly. This includes the labor and materials you put into each product, but not all of the indirect costs such as for distribution and sales.

• Current Assets are all of your cash and anything that can be turned into cash quickly. This includes cash, investments, inventory, and accounts receivable.

• Current Liabilities are all of your debts that need to be paid in the near future. This includes short-term loans from the bank and accounts payable.

• Depreciation is the decrease in an asset’s value over time due to wear and tear, or simply age.

• Double-Entry Accounting is a system that allows you to keep track of all assets, liabilities, and equity. The bookkeeper records every transaction twice in two different journals, once on the left (“debit”) and once on the right (“credit”). In addition to preventing mistakes, the reason each transaction is written twice is to give you a more honest view of your company. If you spend $300 on a credit card to buy a new lighting set up to take photos of your products for your online shop, then your company isn’t magically worth $300 more. It has a $300 new asset to place on the debit side of one account, but it also has a matching $300 liability to place on the credit side of another account.

• Equity is all of the money you invest in the company and all the accumulated profits (that is, the profit you don’t pay yourself to live). Along with liabilities, it is the core way you finance your business activities. Your total equity is approximately how much money you would gain if you liquified your inventory, sold all your assets, and settled all debts.

• Expenses are all of the things you spend money on to operate your business. This can include rent, utilities, wages, and even the interest on your debts.

• Income Statement: The income statement is one of the four main accounting statements along with the balance sheet above. Unlike the balance sheet, which is a snapshot of your company’s financial health, the income statement covers a period of time. It shows all of your revenues and expenses during that time, and (hopefully) the positive difference between them, which is your income.

• Inventory includes all of the items you have purchased for resale but not yet sold.

• Journals are used by bookkeepers to record all of the daily transactions. Each account, for example the accounts payable and receivable mentioned above, has its own journal. These are used by the bookkeeper when performing double-entry accounting.

• Liabilities are just the debts you owe. These range from accounts payable due in the next few days to mortgages you’ll pay off for decades (and student loans forever).

• Payroll is the way you pay your employees, if your company has any. This is a major work function of the bookkeeper because they need to keep track of not just the money owed to employees every Friday, but also the amount that has to be withheld for the government, and all of the other money owed to the government as well. This is a major tax and compliance issue and should be done with care.

• Revenue is the money collected from selling your goods and services. Revenue is one of the major sections of the income statement.

• Trial Balance is a way to test whether your books are in balance before drafting the financial reports and closing the books.

The importance of bookkeeping for your small business

Whether you take on the responsibility of bookkeeping yourself, contract bookkeeping services locally or online, or hire a bookkeeper to handle this work, there are numerous benefits bestowed on your company.

• Foremost, this is the best way to prevent an audit as well as successfully deal with one if a tax authority decides to look more deeply into your company.

• Once up and running, bookkeeping saves you time by putting all the key financial information in one place and in a readable way.

• It will make tax season stress-free (no more stress-eating pickles).

• You can find seasonal or other patterns in your revenue.

• Sudden changes in spending habits are immediately clear.

• The key metrics of your financial health are more visible, including revenue, expenses, profitability, etc.

Putting your bookkeeping data to work

Once you have your books in order and are comfortable with day-to-day bookkeeping, you can unlock the full potential of the information in those spreadsheets through data visualization.

Finding hidden patterns in your sales, seeing the growth potential, and knowing which product is poised to be the star of your marketplace can all be done through using Baremetrics. Data collecting and collating are only the first steps, with data analytics being a necessary next stage to maximize sales and keep on top of those past due accounts receivable.

Frequently Asked Questions

• What is bookkeeping for a SaaS business and how does it differ from standard small business accounting? SaaS bookkeeping applies standard double-entry accounting to subscription revenue models, where recurring billing, deferred revenue, and churn make financial tracking more complex than in a product or services business.In a traditional business, revenue is simple: you sell something, you record the income. In a subscription business, money often hits your account before the service is delivered, which means you carry deferred revenue as a liability until it is earned. You also need to track metrics like monthly recurring revenue (MRR), customer lifetime value (LTV), and churn rate alongside the usual accounts payable, accounts receivable, and payroll. Getting this right matters beyond tax season. Accurate books let you spot spending patterns, model growth, and give investors the clean financial picture they expect from a SaaS operator.
• How do I track recurring revenue and churn in my SaaS bookkeeping without manually updating spreadsheets? Connect your payment processor directly to a subscription analytics platform so MRR, churn, and expansion revenue update in real time without any manual data entry.Spreadsheets work when you have a handful of subscribers, but they break down fast as your subscription business scales. Manual entry introduces errors, and a mistake in your accounts receivable or revenue recognition can distort every downstream metric. Baremetrics connects to Stripe, Braintree, and Recurly and turns that billing data into live dashboards covering MRR, churned MRR, contraction MRR, and LTV, so your subscription KPIs stay in sync with your books automatically. This frees your finance lead to focus on analysis and forecasting rather than data hygiene.Real-time MRR and ARR trackingAutomatic separation of new, expansion, contraction, and churned revenueNo setup or data migration required
• What is the difference between bookkeeping and accounting for a subscription business? Bookkeeping is the daily recording of financial transactions, while accounting uses that recorded data to produce reports, file taxes, and inform strategic decisions for your subscription business.Think of bookkeeping as the foundation and accounting as the structure built on top of it. A bookkeeper keeps your journals current, reconciles accounts payable and receivable, and runs payroll. An accountant takes that clean data to prepare your income statement, balance sheet, and tax returns. For a SaaS founder, both functions matter: without accurate bookkeeping, your accountant cannot produce reliable revenue forecasts or advise on pricing strategy. The distinction also has hiring implications. Many early-stage subscription businesses start with bookkeeping software or a part-time bookkeeper, then layer in an accountant as MRR grows and financial complexity increases.
• When should a SaaS founder switch from spreadsheets to dedicated bookkeeping or subscription analytics software? Move off spreadsheets when manual tracking starts introducing errors, when you have more than a few dozen active subscribers, or when investors ask for clean MRR and churn data you cannot produce quickly.The pickle-jar approach to receipts and the spreadsheet approach to revenue both share the same flaw: they do not scale and they hide problems until those problems are expensive. For subscription businesses, the earliest warning signs are a mismatch between bank deposits and your expected MRR, uncertainty about your actual churn rate, or no clear view of which customer segments are driving expansion revenue versus cancellations. Baremetrics is built specifically for this transition, connecting directly to your existing payment processor and surfacing the subscription metrics, benchmarks, and forecasting dashboards that a spreadsheet simply cannot maintain at volume.
• How can I use subscription analytics to reduce involuntary churn caused by failed payments in my SaaS business? Automated failed payment recovery retries declined cards on an optimised schedule and sends targeted dunning emails, recovering revenue that bookkeeping alone will never catch.Involuntary churn, where subscribers cancel not because they want to leave but because their payment failed, is one of the most preventable revenue leaks in a subscription business. It rarely shows up clearly in standard bookkeeping records until the MRR drop is already baked in. Baremetrics Recover automates the retry logic and customer communication needed to recapture these payments before the subscription lapses. Tracking failed payment recovery alongside your churn analytics gives you a cleaner picture of true customer retention versus billing friction, which matters when you are benchmarking your churn rate or presenting cohort data to investors.Automated smart retries for declined cardsDunning email sequences triggered by payment failureRecovery revenue tracked separately from organic MRR growth
