What it means
For non-finance managers, understanding billings is essential because money requested does not always equal money earned. When you send an invoice to a customer, you create a billing.
However, accounting rules often require you to spread that income over time as you actually deliver the work. This creates a gap between your billings and your revenue.
Why does this matter? Billings are a vital indicator of your sales activity and short-term cash flow expectations.
If your billings are growing, it means your sales team is actively closing deals and issuing invoices. Yet, relying solely on billings can be dangerous.
If you bill a customer upfront for a year-long service, that money sits on your balance sheet as deferred revenue until you actually perform the work each month. In practice, subscription businesses and agencies track billings closely to measure immediate customer demand and cash collection velocity.
By comparing billings to revenue, you can spot potential cash flow crunches before they happen. If billings outpace revenue growth, you have cash coming in, but you also have a growing obligation to deliver future services.
Billings are like handing someone a restaurant bill at the end of the meal. Revenue is the actual eating of the food.
You might hand them the bill all at once, but they digest the meal course by course over an hour.
In practice
Real-world examples
Example 1
A digital marketing agency sends a client a single invoice for $12,000 upfront for a year of website hosting. The total billings for that month equal $12,000, even though the earned revenue is only $1,000. The remaining $11,000 sits as deferred revenue and is released month by month.
Example 2
A manufacturing SME delivers $50,000 worth of custom machinery to a buyer and issues an invoice immediately. Here, the billings and the revenue match closely because the product exchange happens instantly. There is no deferred balance to track.
Example 3
A software company closes an annual enterprise contract worth $24,000, billed quarterly at $6,000. The quarterly billing drives the cash collection schedule, regardless of how intensely the customer uses the software. Revenue, by contrast, is recognised at $2,000 every month.

Formula
Calculation
Deferred Revenue at Start + Total Billings - Revenue Earned = Deferred Revenue at End
Example: A consulting firm starts the month with $5,000 in deferred revenue, issues $20,000 in new billings, and earns $15,000 of revenue by completing projects. Ending deferred revenue is 5,000 + 20,000 - 15,000 = $10,000.
A second angle is to rearrange the formula to find billings from reported figures: Billings = Revenue + Change in Deferred Revenue. If a software firm reports $200,000 of revenue for the quarter and its deferred revenue grew from $80,000 to $110,000, the change is $30,000. Billings are therefore 200,000 + 30,000 = $230,000, which is $30,000 higher than revenue and signals strong prepayments from customers.
Billings also let you track momentum. If the same firm billed $200,000 in the previous quarter and $230,000 in this one, billings grew by (230,000 - 200,000) / 200,000 = 15%. If revenue grew only 5% over the same period, the gap tells you the business is collecting cash ahead of delivery, and that the delivery team will need the capacity to honour those commitments.Case study
Seen in the real world
GreenLeaf Consulting, a fictional environmental advisory firm, experienced rapid sales growth in the spring. To secure upcoming project capacity, the firm required clients to pay 50% of their project fees upfront upon signing contracts. In May, GreenLeaf issued $100,000 in total billings. The founders celebrated this milestone as record-breaking income. However, their accountant quickly pointed out that the actual revenue earned in May was only $40,000, because most of the consulting work had not yet begun.
The remaining $60,000 was logged as deferred revenue, a liability representing the obligation to deliver future advisory services. By tracking billings separately from revenue, GreenLeaf avoided spending cash they had not yet earned, ensuring they had enough working capital to pay their consultants over the summer months. The accountant then built a simple monthly schedule showing how the $60,000 would convert into revenue as projects progressed, for example $20,000 each in June, July and August. This gave the founders a clear view of future earnings and a realistic basis for deciding when to hire an extra consultant.
Watch out
Common mistakes
- Treating billings as equal to revenue, which leads to overspending cash before work is actually performed.
- Failing to track unbilled work, which means missing out on sending invoices for completed tasks.
- Ignoring deferred revenue liabilities when calculating short-term financial health and operational capacity.
Questions
People also ask
Are billings the same as cash collected?
Not necessarily. Billings show the amount you invoiced, but customers might pay late or not at all, which creates bad debt.
Why would billings be higher than revenue?
This happens when you collect payment upfront for services that you will deliver over several months in the future.
Which is more important for a business, billings or revenue?
Both matter equally. Billings show short-term sales momentum and cash flow potential, while revenue shows true long-term business performance.
