Unplanned expenses are expenses that often arise during the implementation of work, projects or business operations. To manage them well, leaders at all levels need to understand where the unplanned expenses come from and how to manage them effectively.
In this article, Bizzi will provide comprehensive information and perspective regarding the costs incurred.
Definition of incidental costs
Incurred expenses are actual expenses that a business must pay or record during the course of business, production or operation – whether paid or not.
Examples of incidental costs:
- Purchase of raw materials and goods
- Pay employees
- Electricity, water, internet, office rental costs
- Advertising and marketing costs
- Cost of machinery repair and equipment maintenance
- Travel, business, and entertainment expenses
Characteristics of incidental costs:
- Actual occurrence at a given point in time (whether money has been spent or not)
- Is the basis for recording in accounting books, helping to determine business results.
- Can be fixed costs (like office rent) or variable costs (like the cost of purchasing raw materials)
- Must have valid documents such as invoices, contracts, acceptance reports... to be legally recorded.
Impact of incidental costs on the company's financial situation
Unexpected costs are an inevitable part of business operations, but if not effectively controlled, they can negatively impact a company's profits, cash flow, and ability to grow sustainably.
Direct impact on profits
The more expenses arise → profit after tax decreases if revenue does not increase accordingly.
- If costs exceed plan → Business may lose money
- If cost control is good → Maintain or increase stable profits
Impact on Cash Flow
Incurred costs, whether paid or not, impact:
- Cash outflow: when making immediate payment
- Expected cash flow: when expenses are incurred but not yet paid (must be paid in the future)
If not managed well, businesses can easily fall into the following situation:
- Cash flow shortage
- Inability to pay wages, taxes, debts
Impact on cost structure and operating efficiency
The costs incurred reflect:
- Where do businesses spend the most (marketing, production, human resources...)?
- High or low cost/revenue ratio → affects operating efficiency
Impact on financial statements and financial ratios
Incurred costs are a factor that affects many key indicators, like:
Index | How affected |
Gross profit margin | Input costs increase → Margin decreases |
Net profit | Operating costs increase → Net profit decreases |
ROA / ROE | Costs increase → Return on assets / capital decreases |
Cost/Revenue Ratio | Increase if not well controlled |
Pressure on management and investment decisions
- Drain the budget
- Impact on expansion plans, new investments
- Leading to the postponement or cancellation of important campaigns

The role of accounting in identifying and tracking costs incurred

How to record costs effectively
Record incurred costs is the accounting or financial management process of recording actual expenses that have occurred during the operation of a business, whether or not the expenses have been paid. This is an important step to accurately reflect the financial situation and operating performance of the business.
Here are ways to record expenses:
Recorded at the right time
- Apply the accrual accounting principle: costs are recorded when incurred, not when paid.
- For example, a service invoice for March, even if paid in April, must still be recorded in March.
Clear cost classification
Cost Type | Typical example |
Production cost | Raw materials, labor, machine wear and tear |
Cost of sales | Advertising, commissions, shipping |
Business management costs | Office supplies, office staff salaries |
Financial costs | Bank interest, exchange rate difference |
Proper classification helps businesses easily track, analyze and evaluate the effectiveness of each department.
Attach costs to each department, project, product
- Set up separate cost codes for each unit or project.
- Helps to retrieve costs by item → evaluate specific performance.
