What a hiring manager scans for in 15 seconds

Hiring managers want to see that you understand the core billing concepts and can apply them to real-world situations. They’re looking for someone who can protect revenue, manage costs, and communicate effectively with stakeholders. Here’s what they scan for:

Understanding of revenue recognition: Can you explain how and when revenue is recognized on a project?
Knowledge of contract terms: Do you understand the payment terms, milestones, and penalties in a contract?
Ability to manage change orders: Can you handle scope changes and their impact on billing?
Experience with different billing methods: Do you know the difference between fixed-price, time-and-materials, and cost-plus billing?
Ability to forecast revenue: Can you accurately predict future revenue based on project progress?

The mistake that quietly kills candidates

The biggest mistake is using jargon without understanding it. It’s obvious to hiring managers when you’re just regurgitating definitions. What’s worse, it’s a red flag to the client when you can’t explain a billing term in plain English. Instead, show that you understand the practical implications of each term.

Use this line to show your understanding: “When we talk about ‘accrued revenue,’ we’re really talking about work we’ve already done but haven’t billed for yet. It’s important to track this closely because it impacts our cash flow and revenue forecast.”

Glossary of Billing Manager Terms

Accrued Revenue

Accrued revenue is revenue that has been earned but not yet billed to the client. For example, if a project is 75% complete but only 50% has been billed, the remaining 25% represents accrued revenue. Accurately tracking accrued revenue is critical for forecasting and financial reporting. Example: A software development project with a total contract value of $500,000 is 80% complete. The company has billed $300,000 to date. The accrued revenue is $100,000 (80% of $500,000 = $400,000 earned – $300,000 billed).

Allowance

An allowance is a specified amount included in the contract to cover certain costs. For example, a construction contract might include an allowance for unforeseen site conditions. If the actual costs exceed the allowance, a change order may be required. Example: A renovation project includes a $10,000 allowance for plumbing upgrades. If the actual plumbing costs are $12,000, a change order for $2,000 would be necessary.

Billing Cycle

The billing cycle is the regular interval at which invoices are sent to clients. Common billing cycles include monthly, quarterly, or upon completion of specific milestones. The billing cycle should be clearly defined in the contract. Example: A marketing agency bills its clients monthly, sending invoices on the last day of each month.

Change Order

A change order is a formal amendment to a contract that documents changes in scope, schedule, or cost. Change orders are typically required for any work outside the original agreement. Example: A construction project requires additional electrical work due to a client request. A change order is issued to cover the additional costs and extend the project timeline.

Cost-Plus Billing

Cost-plus billing is a method where the client is charged for the actual costs incurred, plus a markup for profit. This method is often used when the scope of work is uncertain or difficult to estimate upfront. Example: A consulting firm charges its clients for the actual hours worked by consultants, plus a 20% markup for overhead and profit.

Fixed-Price Billing

Fixed-price billing is a method where the client is charged a predetermined amount for the entire project, regardless of the actual costs incurred. This method provides cost certainty for the client but requires accurate estimation and risk management by the service provider. Example: A web design company charges a client $10,000 for a website redesign, regardless of the number of hours required to complete the project.

Invoice

An invoice is a formal request for payment sent to the client. It should include details such as the services provided, the amount due, and the payment terms. Example: A freelance writer sends an invoice to a client for $500 for writing a blog post.

Milestone Billing

Milestone billing is a method where the client is billed upon completion of specific milestones in the project. This method helps to align payments with project progress and provides transparency for the client. Example: A software development project is divided into three milestones: requirements gathering, development, and testing. The client is billed 30% upon completion of requirements gathering, 50% upon completion of development, and 20% upon completion of testing.

Progress Billing

Progress billing is a method where the client is billed periodically based on the percentage of work completed. This method is often used for long-term projects where it’s impractical to wait until completion to bill the client. Example: A construction company bills its client monthly based on the percentage of the building that has been completed.

Retainer

A retainer is an upfront payment made by the client to secure the services of the service provider. The retainer is typically applied to future invoices. Example: A law firm requires a $5,000 retainer from new clients, which is then applied to their hourly fees.

Revenue Recognition

Revenue recognition is the accounting principle that determines when revenue should be recognized in the financial statements. Generally, revenue should be recognized when it is earned and realized or realizable. Example: A software company sells a subscription license. Revenue is recognized ratably over the subscription period, not all at once when the license is sold.

Time-and-Materials Billing

Time-and-materials billing is a method where the client is charged for the actual time spent on the project, plus the cost of materials. This method is often used when the scope of work is uncertain or difficult to estimate upfront. Example: A repair technician charges the client for the actual hours worked, plus the cost of any parts used.

How to Communicate Billing Terms to Stakeholders

The key is to avoid jargon and use plain language. Explain the concept in simple terms and provide real-world examples. Here are some phrases you can use:

Instead of saying: “We need to recognize the revenue.”
Say: “We need to record the revenue we’ve earned.”
Instead of saying: “We need to issue a change order.”
Say: “We need to formally document this change in scope and its impact on cost and schedule.”
Instead of saying: “This is a fixed-price contract.”
Say: “The total cost of this project is $X, regardless of how many hours we work.”

Use this email to explain a change order:

Subject: Change Order Request for [Project Name]
Hi [Client Name],

As discussed, the recent request for [Specific Change] will require a change order to the original contract. This change will impact the project cost by [Dollar Amount] and extend the timeline by [Number] days. Please review the attached change order document and let me know if you have any questions.

Thanks,
[Your Name]
