Travel Expense Receipts: What to Capture Before You Fly Home

Business travel generates more paper in five days than the rest of your quarter combined, and almost all of it is thermal paper that fades. The receipts you fail to capture on the road are the ones you quietly eat later. Here is what to grab, what to skip, and how to close out the whole trip before the wheels touch down.

The receipts that actually matter

Not every scrap in your pocket is worth filing, but a few categories are non-negotiable because they are the ones most likely to be questioned:

• Lodging. Always keep the itemized hotel folio, not the booking confirmation. The folio separates room rate, city and occupancy taxes, parking, and anything you charged to the room. Those lines often need different treatment in your books.
• Airfare and rail. The e-ticket receipt showing fare, taxes, and fees. Seat selection and bag fees are usually charged separately, so capture those confirmation emails too.
• Ground transport. Rideshare and taxi receipts are small individually and large in aggregate. They are also the first thing to go missing.
• Meals. Meals are treated differently from other travel costs in many jurisdictions, and business meals often need the attendees and purpose recorded. Capture the itemized receipt, not just the card slip, and note who you were with.
• Conference and registration fees. Usually a single large line, and usually easy to prove, so file it immediately and forget it.

What you can skip: anything already flowing through a corporate card feed with a full digital record, and anything purely personal. Filing personal spend just creates work for whoever reviews the report.

Foreign currency: capture the amount you were actually charged

This is where most travel reports fall apart. A restaurant receipt in Lisbon shows euros. Your card statement shows your home currency, at whatever rate your issuer applied, plus a possible foreign transaction fee. Those two numbers will not match, and reconciling them a month later is miserable.

The fix is simple: capture the receipt in its original currency as the source document, and let the card statement supply the settled home-currency amount when it posts. Keep both. If you are asked to substantiate the expense, the original receipt proves what you bought and the statement proves what it cost you. Do not try to convert by hand at the airport using a rate you found on your phone, because that number will be wrong by the time the charge settles.

One more habit worth building: when a card terminal abroad asks whether you want to be charged in your home currency, decline and pay in the local currency. Dynamic currency conversion at the terminal almost always carries a worse rate than your card issuer's.

Scan at the point of transaction, not at the gate

The single highest-leverage habit in travel expenses is scanning each receipt the moment it hits your hand. Thermal paper degrades with heat and light, and a receipt that spent three days in a jacket pocket in July may be genuinely unreadable by the time you get home. Beyond legibility, you lose context fast: on day one you know exactly why that dinner mattered, and by day five it is one of six dinners.

The practical routine looks like this:

1. Photograph the receipt at the table, in the cab, at the hotel desk. Curled and crumpled is fine.
2. Let the scan pull merchant, date, total, tax, and line items so nothing is retyped later.
3. Confirm the suggested category while the trip is still in your head, and add the business purpose or attendees if it was a meal.

Three seconds per receipt on the road replaces an hour of archaeology the following week. Because Expense Rabbit syncs one account across iPhone and the web, you can capture on your phone in a taxi and finish the report from a laptop at the hotel without moving anything by hand.

Close the trip out before you land

A flight home is dead time with no notifications, which makes it the best expense-filing window you will get all month. By then every receipt should already be captured, so the remaining work is review rather than data entry: check that each scan has the right category and confidence, add purpose notes to the meals, and flag anything personal so it never enters the report.

Then export a books-ready CSV and hand the whole trip off in one file. Your accountant or approver gets clean rows instead of a photo album, and you get to walk out of the terminal with the trip genuinely finished.

Keep the records longer than you think you need to

Travel expenses attract scrutiny because they mix business and personal life so easily. Retention rules vary by country and situation, but the common guidance runs to several years after filing, and longer in some circumstances. Digital copies cost nothing to store, so the low-effort answer is to keep every trip indefinitely rather than trying to remember which year you are allowed to purge. A searchable archive also means that when someone asks about a hotel charge from two Marches ago, you answer in ten seconds instead of ten minutes.
