How to Reduce Business Costs and Expenses

Here’s one of the clearest opportunities for finance leaders to improve margins without slowing growth: Build cost controls that hold up in day-to-day operations, not just during periodic cost-reduction pushes. The programs that last usually share the same foundation: better visibility, stronger controls, and systems that connect company policy to employee spending in real time.

Travel and expense (T&E) is one of the most visible and controllable categories within selling, general, and administrative (SG&A) costs. It also gives finance and accounting teams direct ways to improve outcomes through consolidation, real-time policy enforcement, and faster access to spending data. This guide covers seven strategies for reducing business costs associated with T&E, where finance and accounting teams have the most direct leverage and the most influence over whether savings last.

Where Durable Cost Control Starts

Durable cost reduction starts with operating systems and habits that hold up after the initial push. The real opportunity is building controls that continue to guide spending as teams return to their normal workflows.

T&E spending is a strong example of that opportunity. Organizations negotiate preferred rates with airlines and hotels, build approval workflows, and set per-diem limits, but the connection between those policies and actual employee behavior often needs to be stronger. The State of Corporate Travel and Expense 2026, a report from Skift and Navan, found that 80% of business travelers surveyed sometimes book off-platform because they believe they can find better prices or more convenient options elsewhere. When bookings move off-platform, negotiated rates may go unused, spending data may arrive later, and finance and accounting teams may have a harder time managing budgets in real time.

7 Strategies to Reduce Business Costs Without Cutting Growth

T&E cost gaps are largely a visibility and enforcement problem. When spend moves off-platform, policy violations surface weeks late, and negotiated rates go unused, it’s often because the issue wasn’t caught at the right moment. The seven strategies below address that problem at each level: how data flows between systems, how policy gets enforced at the point of spend, and how employees are motivated to stay on-channel.

1. Consolidate Travel and Expense Onto a Single Platform

Fragmented T&E management makes spending harder to control and more expensive to reconcile. When those tools live in separate systems, teams spend more time on reconciliation than on analysis. T&E managers recognize the problem. It’s why Skift and Navan’s 2026 State of Corporate Travel and Expense report found that 77% of managers surveyed prioritize an all-in-one T&E approach. Disconnected tools can create visibility gaps between bookings, spend, and reporting — those gaps make it harder to spot where costs are running high.

Consolidation can generate savings in two ways. First, it can help eliminate redundant software licensing and administrative overhead. It can also create a single source of spend data that makes patterns visible, such as which suppliers cost more than negotiated, which departments consistently exceed budgets, and which policy rules need updating.

That’s exactly what Navan’s consolidated approach can do. It brings travel booking, travel management, expense management, payments, corporate cards, and analytics onto one platform, giving finance and accounting teams a more complete view of T&E spending without manual data consolidation.

2. Enforce Spending Policies at the Point of Transaction

The best time to catch a policy violation is before money changes hands. Many organizations have detailed policies covering spending limits, preferred suppliers, and approval thresholds, but those rules create more value when they surface during the booking or payment workflow, before money has been committed.

The most effective enforcement happens upstream, but in two different ways.

• For travel booking: Platforms can surface compliant flight and hotel options first, flag exceptions in real time, and route out-of-policy requests to the right approver before travel is booked.
• For expense transactions: The expense policy system applies rules at the point of swipe, shifting more of the burden from post-trip auditing to proactive controls that can help prevent overspending at the source.

Navan applies configurable policy rules at the point of swipe, where transactions are auto-approved, flagged for review, or declined, helping catch out-of-policy expenses before they’re reimbursed.

3. Automate Expense Processing to Recover Productivity

Every expense report filed manually is a collection of steps that could largely be handled automatically. Employees often spend too much time on steps that could largely be automated:

• Sorting receipts
• Coding transactions to the right general ledger accounts
• Chasing missing documentation
• Correcting errors that can compound during month-end tasks

Automation can address each of these friction points. When expense data is captured at the point of transaction through corporate card feeds, receipt scanning, and automatic categorization, the manual steps that consume hours per week can largely disappear. In a Forrester Consulting Total Economic Impact™ study commissioned by Navan, organizations using Navan reported that employees save 24 minutes per expense report. That kind of time recovery can cut administrative work for employees while giving finance and accounting teams cleaner data to work with.

4. Audit Negotiated Rates to Recover Contracted Savings

Most companies already have strong supplier contracts in place, but negotiated rates only deliver savings when they’re actually used. The opportunity is in verifying whether those rates appear in bookings and invoices.

Those discrepancies show up in predictable ways:

• Data entry errors that applied a small discount instead of a much larger one
• Contracted rates treated as floors instead of caps
• Chain-wide hotel discounts that simply weren’t loaded correctly

Individual recovery amounts, just from contracts already in place, can be substantial.

Start by comparing what your preferred suppliers contracted to deliver against what your employees paid. If your booking platform doesn’t surface this data automatically, some portion of your negotiated savings may be leaking at the point of purchase.

5. Use AI to Flag Violations Before Funds Leave the Account

Traditional audit processes work by sampling, which means most transactions never get a second look. Instead of sampling a fraction of expense reports after reimbursement, AI tools can continuously review transactions as they happen, matching receipts, checking policy compliance, and surfacing anomalies before funds are disbursed.

The timing compounds the problem. By the time a sampled transaction surfaces an issue, the money has often already moved. With enough transaction context, automated review can help finance and accounting teams catch problems earlier and focus manual effort where it matters most.

Navan’s platform, for instance, captures 110+ data points per booking and 130+ per expense transaction, giving the solution’s Audit Agent the context to surface anomalies and out-of-policy spend that might otherwise require manual review.

6. Incentivize Employees to Book Within Policy

Travelers book outside the corporate tool when they believe they can find a better deal on their own. Policy compliance tends to improve when employees have a reason to follow the rules beyond “because the policy says so.” Financial incentives that reward under-budget bookings can help align traveler behavior with company cost goals.

Navan Rewards puts this principle into practice by giving employees a personal incentive, such as cash rewards for personal travel, when they book travel options below the company’s policy cap. Travelers still choose freely, with a reason to pick the lower-cost option. The result can be lower average trip costs without the friction that comes from hard spending limits.

7. Replace Periodic Cost Cuts With Continuous Cost Discipline

Periodic cost-cutting campaigns have a shelf life. The savings from an initial push tend to erode as teams return to familiar habits, unless controls stay active between reviews. The most effective programs treat cost and expense management as a permanent operating capability, running continuously rather than in cycles.

Building continuous cost discipline means:

• Investing in real-time visibility rather than monthly reporting cycles
• Setting up automated alerts when spending trends shift
• Reviewing policy rules against actual data rather than annual assumptions

When your T&E platform captures every booking and transaction as it happens, your finance team can shift from discovering problems during close to preventing them throughout the month. Every strategy above depends on one underlying condition: employees using the systems consistently enough to keep spending visible and on-channel.

Why Adoption Determines Whether Cost Reductions Work

Adoption is what turns policy, visibility, and automation into real savings. Every strategy above depends on whether employees use the systems you’ve put in place. A platform with strong policy controls, negotiated rates, and intelligent automation is still only as effective as its adoption rate. When travelers book off-channel, the gaps compound quickly. Visibility drops, negotiated rates go unused, and expense data arrives weeks late.

That pattern shows up consistently. A substantial share of business travelers, even those who know their company has a booking tool, still book outside managed channels. The reasons are practical:

• They believe they’ll find a better price
• They want to manage their travel preferences directly
• The corporate tool is slower than consumer alternatives

Improving adoption starts with removing those friction points. Booking needs to be as fast as a consumer app. Navan reports an average booking speed of 7 minutes compared to more than 45 minutes on legacy platforms. Support needs to be available around the clock, not just during business hours.

Change management matters, too. Organizations that treat technology rollouts as purely IT projects tend to underfund the employee impact of the change. Successful implementations typically include:

• Executive sponsorship from finance leadership
• Role-specific training for travelers and approvers
• Phased rollouts starting with high-travel departments
• Visible adoption metrics shared with department heads

Those steps reduce the organizational lift, but ease of use determines how much lift the organization needs in the first place. The Forrester TEI study highlights ease of use as an unquantified benefit — one that keeps adoption high well after the initial rollout.

From Cost-Cutting to Cost Control

If you want durable cost control, you need systems that keep policy, spend, and visibility connected in real time. When your T&E platform enforces policy at the point of booking, automates the manual work, and surfaces current spend in real time, cost management can shift from a periodic exercise to something that runs continuously.

That shift is what makes the strategies in this guide work together. Consolidate travel and expense data and you can see where money is going. That visibility makes earlier policy enforcement possible. Problems get caught before they show up in reports. Add consistent adoption, and your negotiated rates, budgets, and forecasts stay tied to what people are actually doing day to day.

What makes cost control last is a process your teams will keep using and a platform that keeps spending aligned with policy while decisions are still being made. When you close the gap between what your organization plans to spend and what it spends, cost control becomes more consistent, more durable, and easier to sustain without slowing growth.
