Match The Following Overhead Costs With Their Source Documents.

Let's unravel the connection between overhead costs and the essential source documents that provide their validation and tracking. Accurately matching overhead costs to their source documents is crucial for robust financial reporting, informed decision-making, and efficient cost management. This process forms the backbone of managerial accounting, allowing businesses to understand the true cost of their products or services and improve profitability.

The Significance of Source Documents in Overhead Costing

Overhead costs, by their very nature, are indirect. They are the expenses incurred to support the overall operations of a business but cannot be directly traced to a specific product or service. Examples include rent, utilities, administrative salaries, and depreciation. Without proper source documents, allocating these costs accurately becomes a challenge, leading to potentially skewed financial data and flawed strategic decisions.

Source documents serve as the audit trail for overhead costs. They provide verifiable evidence that a cost was incurred, its amount, and its purpose. They're essential for:

Accuracy: Ensuring the reliability of cost information.
Transparency: Providing a clear record of how overhead costs are allocated.
Compliance: Meeting regulatory requirements and internal control standards.
Decision-making: Enabling informed decisions about pricing, production, and resource allocation.
Auditing: Facilitating internal and external audits of financial statements.

Common Overhead Costs and Their Corresponding Source Documents

To effectively match overhead costs with their source documents, it's important to understand the types of costs typically classified as overhead and the documentation generated when these costs are incurred. Here's a detailed breakdown:

1. Rent/Lease Payments

Overhead Cost: The cost of renting or leasing the facilities used for production, administration, or storage.
Source Document: Lease Agreement. The lease agreement outlines the terms of the lease, including the monthly rent amount, the duration of the lease, and any other relevant conditions. Rent Receipts or Bank Statements serve as proof of payment, confirming that the rent was paid as agreed upon.

2. Utilities (Electricity, Water, Gas)

Overhead Cost: The cost of electricity, water, gas, and other utilities used in the business operations.
Source Document: Utility Bills. These bills detail the consumption of each utility, the billing period, and the amount due. These bills are usually accompanied by consumption reports which further shows the amount of utility consumed during the period.

3. Depreciation

Overhead Cost: The allocation of the cost of a tangible asset (e.g., machinery, equipment, buildings) over its useful life.
Source Document: Depreciation Schedule. A depreciation schedule outlines the cost of each asset, its useful life, the depreciation method used (e.g., straight-line, declining balance), and the annual depreciation expense. The original Purchase Invoice for the asset provides the initial cost basis.

4. Salaries and Wages (Indirect Labor)

Overhead Cost: The salaries and wages of employees whose work supports the production process but who are not directly involved in creating the product or service (e.g., supervisors, maintenance staff, administrative personnel).
Source Document: Payroll Records. Payroll records include employee timesheets, payroll registers, and pay stubs. These documents detail the hours worked, the pay rate, and the gross pay for each employee. Labor Distribution Reports summarize labor costs and allocate them to different departments or cost centers.

5. Insurance

Overhead Cost: The cost of insurance policies that protect the business against various risks (e.g., property damage, liability).
Source Document: Insurance Policies. Insurance policies outline the coverage provided, the policy period, and the premium amount. Invoices from the insurance company and Proof of Payment (e.g., cancelled checks, bank statements) verify the premium payments.

6. Maintenance and Repairs

Overhead Cost: The cost of maintaining and repairing equipment, machinery, and facilities.
Source Document: Maintenance Work Orders. These documents describe the work performed, the date of the service, the materials used, and the labor hours involved. Invoices from the maintenance service provider and Material Requisition Forms (for materials used from inventory) provide further details.

7. Supplies (Indirect Materials)

Overhead Cost: The cost of materials that are used in the production process but are not directly incorporated into the finished product (e.g., cleaning supplies, lubricants, office supplies).
Source Document: Material Requisition Forms. These forms authorize the withdrawal of materials from inventory. Purchase Invoices for the supplies and Inventory Records provide information on the cost and quantity of supplies used.

8. Property Taxes

Overhead Cost: Taxes levied on the value of the company's property (e.g., land, buildings).
Source Document: Property Tax Bills. These bills state the assessed value of the property, the tax rate, and the amount due. Payment Records (e.g., cancelled checks, bank statements) confirm the tax payments.

9. Advertising and Marketing

Overhead Cost: The cost of promoting the company's products or services. Note: some advertising can be directly attributable, but often, broader campaigns fall under overhead.
Source Document: Advertising Contracts. Contracts with advertising agencies or media outlets outline the terms of the advertising campaign, including the cost, duration, and reach. Invoices from the advertising agency and Proof of Performance Reports (showing ad impressions, website traffic, etc.) provide supporting documentation.

10. Research and Development (R&D)

Overhead Cost: The cost of activities aimed at developing new products or improving existing ones. (Note: Some R&D may be capitalized rather than expensed, but the portion that is expensed falls under overhead).
Source Document: Project Budgets. These budgets outline the planned expenses for each R&D project. Time Sheets for R&D personnel, Purchase Orders for materials and equipment, and Lab Notebooks documenting experiments and findings provide detailed cost information.

11. Quality Control

Overhead Cost: Costs associated with ensuring the quality of products or services.
Source Document: Inspection Reports. These reports document the results of quality control inspections, including any defects found and corrective actions taken. Equipment Calibration Records ensure that testing equipment is accurate. Employee Timesheets for quality control personnel track labor costs.

12. Training and Development

Overhead Cost: Costs associated with training employees to improve their skills and knowledge.
Source Document: Training Schedules. These schedules outline the dates, times, and topics of training sessions. Attendance Records verify employee participation. Invoices from training providers and Employee Timesheets (if internal trainers are used) document the costs.

Establishing a System for Matching Overhead Costs with Source Documents

Effectively matching overhead costs with their source documents requires a systematic approach. Here are key steps to implement:

Develop a Chart of Accounts: Establish a comprehensive chart of accounts that clearly defines each overhead cost category. This provides a standardized framework for recording and classifying expenses.
Implement a Document Management System: Implement either a physical or electronic document management system to organize and store source documents. Electronic systems offer advantages such as improved searchability, security, and accessibility.
Establish Clear Procedures: Develop written procedures for processing and approving overhead cost invoices and other source documents. These procedures should outline the roles and responsibilities of different departments and individuals.
Train Employees: Provide training to employees on the importance of accurate record-keeping and the proper procedures for submitting and processing source documents.
Regularly Reconcile Accounts: Regularly reconcile overhead cost accounts with supporting documentation to ensure accuracy and identify any discrepancies. Investigate and resolve any discrepancies promptly.
Utilize Accounting Software: Leverage accounting software to automate the process of matching overhead costs with source documents. Many accounting software packages offer features such as document scanning, automated data entry, and electronic workflow.
Perform Internal Audits: Conduct periodic internal audits to assess the effectiveness of the overhead cost management system and identify areas for improvement.
