Billable expenses like travel, meals, client entertainment, and project supplies could add up quickly, and someone may need to track, categorize, and determine whether those costs may be passed along.
But processing billable expenses doesn’t have to be a hassle. With the right tools and processes in place, handling billable expenses may feel more manageable. Better visibility, automated tracking, and clear guidelines may help limit time spent chasing receipts and keep cash flow easier to manage.
What Is a Billable Expense?
A billable expense is a cost a business pays while doing work for a client, and then passes along to that client for reimbursement. If the expense is related to a client’s project, it may be billable.
For example, imagine you’re working on a client project that requires travel, special materials, or third-party services. If those costs were incurred to support that client, they may be billable.
Examples of Billable Expenses
Billable expenses may vary by business and may include:
- Client travel costs, such as flights, hotels, or meals
- Materials or supplies purchased for a project
- Shipping or courier fees tied to client work
- Fees for subcontractors or specialists
- Project-specific software, licenses, or stock photography
These expenses may be listed on an invoice so clients may see exactly what they’re paying for. However, what qualifies as “billable” may depend on the client agreement or contract.
Billable vs. Non-Billable Expenses
One simple question may help clarify the difference between billable and non-billable expenses: Would this cost exist without the client?
If the answer is no, it may be billable.
If the answer is yes, it may be non-billable. Everyday costs — such as rent, utilities, insurance, software subscriptions, and employee salaries — support overall business operations and may not be passed along to clients.
What Is the Difference Between Billable and Reimbursable Expenses?
Billable and reimbursable expenses could be closely related but may play different roles in how costs are tracked and recovered.
Reimbursable Expenses
Reimbursable expenses are costs employees or contractors pay upfront and are later paid back by the company. These are internal expenses and usually don't directly involve the client. Common examples may include:
- Meals during business travel
- Hotel stays for work-related trips
- Taxi, rideshare, or public transportation costs
The employee or contractor submits the expense, it’s reviewed and if approved, the company reimburses them.
Billable Expenses
Billable expenses, on the other hand, are costs incurred specifically for a client and charged to that client, typically through an invoice. Examples may include:
- Travel costs to attend a client meeting or work on-site
- Software or tools purchased for a specific client project
- Courier or shipping fees for client deliverables
Reimbursable expenses may feed into billable ones. For example, an employee may pay for a business lunch with the client, be reimbursed by the company, and then that cost is included on the client’s invoice. Internally, it’s reimbursable. Externally, it’s billable.
What matters may be the purpose of the expense. If the cost exists to serve a client and aligns with the agreement in place, it may be considered billable — regardless of who paid first.
Why Billable Expense Management Matters
When billable expenses aren’t tracked carefully, businesses may end up absorbing costs that could have otherwise been reimbursed. Over time, small, missed expenses could snowball and put pressure on project margins.
Clear, consistent tracking could help support accurate invoicing, faster reimbursements, and fewer misunderstandings. A carefully considered expense management system could also help save time, support transparency, and build stronger client trust.
Best Practices for Managing Billable Expenses
Managing billable expenses doesn’t have to be complicated, but it may benefit from consistency, coordination, and collaboration across teams. Consider these tips:
1. Set clear rules up front.
Before a project starts, consider defining which expenses are billable or reimbursable, how they should be documented, and when they’ll be invoiced. Setting expectations early on may help reduce confusion (or avoid the need for uncomfortable conversations) later.
2. Communicate expectations clearly.
Consider sharing expense guidelines with both clients and internal teams to help ensure everyone is on the same page. For clients, billable expense terms may be outlined in contracts or written agreements, while employees may benefit from written expense policies and training.
3. Require documentation.
Receipts, notes, and descriptions may be used to help support accurate records, speed up approvals, and provide transparency for clients.
4. Keep billable expenses separate.
Consider keeping billable, reimbursable, and non-billable expenses separate. Separating these from the get-go may help streamline expense report integration and help ensure eligible costs make it onto client invoices.
5. Track and invoice promptly.
Encouraging timely tracking of costs may help keep records accurate and organized. The same may also help for invoicing. Sending bills sooner rather than later could help improve cash flow and minimize back-and-forth “what’s this for?” conversations with clients.
6. Tap into technology.
Spreadsheets and email chains could slow things down and leave room for error. Expenses might get buried in inboxes, specifics might get missed, and time that could go towards actual work could end up lost to follow-ups and fixes.
That’s where technology may help automate the process. Expense management tools could be used to centralize tracking, categorization, reporting, and invoicing, potentially making costs easier to organize and review.
Technology could also help support more complex needs, such as partial billing, splitting expenses across clients or cost centers, tagging expenses accurately, and keeping documentation tied to each charge.
A Proactive Approach to Managing Your Billable Expenses
Billable expenses don’t have to be a source of stress or guesswork. With clear policies, better communication, and the right tools and technology, expense management may even feel more streamlined. This could mean fewer missed charges, faster reimbursements, and more confidence in your accounting systems.
Once billable expenses are under control, it may be time to take a broader look at business spending and consider how to manage everyday costs more effectively. Learn more about common business expenses and using credit cards to help manage them.
