Building a spend policy that doesn’t feel bureaucratic

An employee spending policy should bring order to company finances. But, too often, it does the opposite. For instance, over 80% of employees struggle with travel expenses, with about 20% stating they’re unsure which expenses are reimbursable, according to an industry report. This likely isn’t the employee experience you’re looking to deliver, but it’s all too common.

Many spend policies read like they were written for large corporations, full of clauses and approval ladders that slow teams down. The result? Employees find workarounds, finance teams lose visibility, and spending turns into a guessing game. And running a business without a spend policy at all is just as risky. Surprise expenses pile up, reimbursements become inconsistent, and accountability fades as the team grows. 

A good employee spending policy strikes a balance between clarity and autonomy, offering guidance that keeps things fair, efficient, and aligned with your goals.

This guide shows how to build in more balance to your employee expense policy. You’ll learn what makes a healthy spend policy, how to write one that people will actually respect, and what mistakes to avoid. The goal is to create a shared understanding, so everyone can move fast and spend wisely.

Startups often pride themselves on speed, flat structure, and trust. Formalizing an employee expense policy can feel like you’re betraying that culture or signaling that you’ve gone corporate. But a policy doesn’t have to mean hierarchy or distrust. Done right, it actually can build trust by making expectations clear.

Without a written employee spending policy, teams rely on assumptions, and those assumptions may differ. For example, one person might think client dinners are reimbursable; another might assume they’re not. Some might front large expenses without realizing how long repayment takes, and others may avoid necessary purchases to stay “safe.” Over time, this inconsistency breeds inequity, resentment, and confusion.

Informality also hurts financial visibility. When everyone uses personal cards or submits receipts on an ad-hoc basis, finance teams spend hours untangling transactions. That’s time better spent forecasting or managing cash flow.

A thoughtful employee spending policy is about alignment, not control. It clarifies what’s OK to spend money on, who approves what, and how decisions tie to company goals. It also makes cash flow more predictable and avoids budget surprises. For employees, it removes guesswork and awkward moments of second-guessing.

Done well, your policy becomes a safety net that protects both your company culture and your runway, giving everyone more confidence to make good decisions.

A strong employee expense reimbursement policy gives teams clarity, without overcomplicating how they work. It should be simple enough to skim, but detailed enough to guide real decisions.

What types of expenses are covered

Start by outlining what the company will and won’t pay for. Be explicit about categories, such as travel, meals, software, client entertainment, and education. If you reimburse software licenses and other tools, note how to request them.

Instead of vague language like “Travel expenses must be reasonable,” define what that means, whether that’s economy flights under a set amount, mid-range hotels, or daily meal limits. When people understand what “reasonable” means, they can spend with confidence.

Who can spend what (and when)

For effective allocation of resources, define spending limits by role, team, or project. Some companies prefer dollar-based thresholds. (For example, managers can approve up to $1,000.) Others use pre-approved budgets or corporate cards. If you use virtual cards, explain how employees access and manage them.

Good policies balance flexibility and trust. Approvers should feel empowered to make judgment calls, not boxed in by rigid rules.

How approvals and reimbursements work

Even the clearest employee expense policy can fail, if people don’t understand the process. Lay out how expenses are approved and reimbursed, and what documentation is required. Do receipts need to be uploaded? Should expenses be submitted through a specific tool? How long do reimbursements take?

Automation can simplify this. Modern tools, including Mercury’s spend management features, allow you to create card-level controls, assign budgets, and review transactions in real time.

If you offer reimbursement for out-of-pocket purchases, keep the process fast. Long waits for repayment can erode trust, especially among early employees who are personally covering costs. A clear employee business expense reimbursement policy ensures fairness and prevents financial strain for your team.

Too many spend policies read like legal documents and seem designed to catch mistakes, rather than prevent them. The goal is to write something people understand and trust.

Use clear, friendly language

A conversational tone feels approachable and shows respect for your employees’people’s time and judgment. 

Avoid the urge to sound overly official. Corporate jargon creates distance, whereas plain language builds connection. For example, instead of stating, “Employees are required to obtain prior authorization for discretionary expenditures exceeding the allocated threshold,” try saying something more direct, like “Get approval from your manager before spending more than $500.” 

Avoid a tone that feels mistrustful

A policy full of warnings and penalties creates tension before anyone even submits an expense. Instead, assume good intent. Frame your rules around empowerment and protection. Phrases like, “Use your best judgment when spending company money,” acknowledge trust while still setting expectations. When people feel trusted, they’re more likely to act responsibly and transparently.

Offer examples or scenarios for clarity

Policies work best when they help people think, not just comply. Short “if this, then that” examples help employees reason through spending decisions. 

For example:

• “If you’re traveling for a client meeting, book the most direct economy flight available.”
• “If you need new software, check whether we already have a tool that does the job before buying another license.”

TL;DR: Writing a policy people will actually follow

Keep it simple, human, and helpful. Use plain language instead of jargon, assume good intent, and frame rules as guidance, rather than restriction. Give real-life examples that show how decisions should be made in context, and make the policy document easy to scan. 

When people understand the “why” behind your policy and can find answers quickly, they’re more likely to trust and follow it.

Even when written with the best intentions, a spend policy can turn into a source of frustration if it’s not designed thoughtfully. As your company grows, try to maintain a structured approach without compromising flexibility.

Making it too rigid or punitive

A strict policy can slow people down and signal a lack of trust. Employees may hesitate to spend or find ways around the rules. Keep the focus on clarity and empowerment. Instead of long lists of forbidden expenses, emphasize principles like “Spend company money as carefully as you would your own.”

Creating too many approval layers

Requiring multiple sign-offs can create bottlenecks. When approvals are slow, teams may resort to using personal cards or delaying purchases, which creates additional accounting work later. Set clear thresholds for approval and automate the rest.

Not revisiting the policy as the team grows

A policy that works for 10 people won’t always work for 50. As new teams form, spending habits change. Review your policy every six to 12 months. Gather feedback from managers and employees who use it most often. This process will help catch gaps early and show your team that the policy is a living document, not an inflexible rulebook.

Ignoring employee feedback

Your team interacts with your policy on a daily basis., and they know where the friction points are. Maybe they feel the frustration of slow approvals, unclear categories, or confusing reimbursement steps. Ask for their input through quick surveys or regular check-ins with team leads. Small changes can make a big difference. When people feel heard, they’re more invested in following and improving the policy together.

An effective employee spending policy is clear and fair, giving your team the confidence to move faster. Instead of seeing your spend policy as red tape, think of it as infrastructure. The right structure helps everyone make better decisions with less friction. When done well, it will foster shared trust and accountability that keeps your company agile as it grows.

Expense management will always be part of building a business. However, when expectations are simple, transparent, and backed by tools that make compliance easy, the conversation shifts from “What’s allowed?” to “What’s best for the business?” That’s how clarity becomes culture, and how smart teams stay nimble.
