Navigating Sundry Expenses in Business Travel: The Hidden Costs of T&E

concierge service

Think about the last business trip you approved. You probably focused on the big ticket items like the flight across the country or the three-night stay at a downtown hotel. But travel costs are rarely that simple. It is the $5 tip for the hotel concierge, the emergency Wi-Fi access at the airport, or that double espresso during a long layover. These are Sundry Expenses in Business Travel. They are the small, often annoying costs that create a massive headache for finance teams when they go unnoticed.

Individually, these items look like nothing. But when you add them up across a whole department? They are surprisingly expensive. 

With global business travel spend projected to reach $1.48 trillion in 2024, unmanaged “miscellaneous” spending can quietly eat up a huge chunk of your T&E budget. For finance managers, the problem is not just the cost itself. It is the lack of visibility. You cannot manage what you cannot see.

TL;DR

  • The Gist: Sundry expenses are those small, irregular costs that do not fit into neat accounting boxes.
  • The Trap: In business travel, we are talking about tips, currency fees, and forgotten toiletries.
  • The Risk: If you treat the “sundry” ledger as a dumping ground, you risk tax compliance issues and audit failures.
  • The Fix: Don’t rely on manual entry. Automation is the only way to stop fraud in this category.
  • The Tool: Modern platforms like itilite auto-categorize these receipts so you don’t have to.

What Are Sundry Expenses in Business Travel?

If you want to control your budget, you have to define the edges of it. Sundry expenses in business travel are the miscellaneous, infrequent, and usually small costs that happen during a trip. They don’t fall under the major headlines like “Airfare” or “Client Entertainment.”

Because these expenses happen so irregularly, it makes no sense to create a specific General Ledger (GL) code for every single one. Yet, your travelers need them to keep things running smoothly.

Characteristics of Sundry Expenses

  • They are random: You cannot predict them like a monthly software subscription.
  • They are small: The dollar value is usually low.
  • They are necessary: Even though they are minor, the trip might stall without them.

Common Examples in T&E

  1. Gratuities: The cash tips for porters, housekeeping staff, or valets.
  2. Staying Connected: In-flight Wi-Fi charges or a day pass for an airport lounge during a delay.
  3. Bank Fees: The cost to exchange foreign currency or ATM withdrawal charges.
  4. Personal Care: Emergency laundry if a trip gets extended or toothpaste forgotten at home (depending on your policy).
  5. Paperwork: Visa fees paid on arrival or local tourist taxes.

Differentiating Sundry Expenses vs. General Expenses

It is vital for accounting teams to know the difference between a sundry expense and a general operating expense. If you mix them up, your financial statements get messy.

1. Sundry vs. General Operating Expenses

General expenses are the heartbeat of the business. They are recurring and predictable. We are talking about office rent, salaries, or the annual company retreat. You have dedicated GL codes for these because you know they are coming.

Sundry expenses are the odd ones out. They are too random to deserve their own category, but they are still legitimate business costs.

Think of it this way: A monthly retainer for a travel agency is a General Expense. A one-time fee to replace a lost passport while abroad is a Sundry Expense.

2. The “Petty Cash” Confusion

People often mix up sundry expenses with petty cash, but they are not the same thing.

  • Petty Cash is just a way to pay (usually a physical box of money).
  • Sundry is an expense category.
  • Note: You can pay for a sundry expense with a corporate credit card. It does not have to be cash.

3. Recording Sundry Expenses in Accounting

Just because you label an expense “sundry” does not mean you can ignore it. If you record these incorrectly, you might run into trouble during tax season.

The Importance of the “Sundry” Ledger Account

In your chart of accounts, you likely have a “Miscellaneous Expenses” or “Sundry Expenses” line. The danger is letting this account become a “junk drawer” for mystery spending.

  • Set a Limit: You need a threshold. If your “Sundry” account suddenly eats up more than 5% of your total T&E spend, that should trigger an immediate audit.
  • Watch the Taxes: Not every sundry item is tax-deductible. A baggage fee is usually fine, but if an employee categorizes a personal movie rental as “sundry,” that is a problem.

How to Record Them Efficiently

  1. Digital Trails: Even for small amounts, get the receipt. No exceptions.
  2. GL Coding: Accurate entries usually debit the Sundry Expense account and credit the Bank or Credit Card account.
  3. Regular Reviews: Look at the ledger every month. Sometimes a recurring cost, like a new SaaS tool subscription, tries to hide in there.

Challenges and Solutions in Managing Sundry Expenses

The biggest risk with sundry expenses in business travel is the lack of control. When employees realize there is a “miscellaneous” category, it can quickly become a hiding spot for out-of-policy purchases.

The Risk of Expense Fraud

Without someone watching closely, “sundry” is where expense fraud thrives. It starts small. A $20 charge here, a $15 charge there. It looks like nothing, but it adds up.

According to the ACFE’s 2024 report, expense reimbursement schemes account for roughly 13% of asset misappropriation fraud, with a median loss of $50,000. A vague “miscellaneous” charge could actually be a personal purchase, and these small leaks eventually sink the ship.

Automating the Process with itilite

Trying to track these small receipts manually is a waste of your finance team’s time. This is where you need automation.

itilite changes how you handle these loose ends:

  • Smarter Categorization: We don’t just dump everything into “Sundry.” itilite’s OCR technology scans receipts and suggests specific categories automatically.
  • Real Policy Checks: You can set hard rules, like “No miscellaneous expenses over $50 without a manager’s explanation.”
  • Ready for Audit: Every small receipt is digitized and stored. When tax season hits, you won’t be chasing paper scraps.

Conclusion

Sundry expenses in business travel might look small on their own. But if you ignore them, they turn into a significant financial risk. By defining them clearly, keeping them separate from general costs, and using automated tools to watch the ledger, you can turn a chaotic “miscellaneous” account into a clean part of your financial reporting.
