Business travel invoices: what your company should keep

Every business trip produces a stack of documents: the agency invoice, the airline ticket, the hotel bill, the car rental receipt, taxi and meal receipts. When these papers are scattered across inboxes, wallets and phones, the cost shows up at month-end close: entries without support, hotel invoices issued in the traveler’s personal name and hours spent chasing documents from people who are already back at work.

Managing business travel invoices is less about bureaucracy and more about method. At ArrowTur, which has managed corporate travel in Brazil since 1989, we see that companies that close the month without surprises combine three things: few payment points, clear rules on the data each document must carry and a digital file linked to each trip. Here is how to set up that process.

Why travel documentation matters

A tax document proves that the expense happened, that it was incurred for the company and that it relates to the company’s business. Without it, the accounting entry is weak and may be challenged in an audit or a tax inspection. Documentation is also what lets you check whether the trip followed the travel policy, allocate the cost to the right cost center and negotiate better with suppliers based on real data.

The tax treatment of each expense (what is deductible, which credits can be used and how long each document must be kept) is set by law and depends on the company’s tax regime. In Brazil, most suppliers issue a “nota fiscal”, the official electronic invoice registered with the tax authorities. The golden rule is simple: agree with your accountants on what must be kept and turn it into a procedure in your travel policy.

Which document each expense generates

Each travel service has its own proof of expense. Knowing the difference avoids asking a supplier for a document it does not issue:

• Travel agency: issues an invoice detailing the services and a service invoice (nota fiscal de serviço) for its own fee, such as the service fee. Amounts passed on to airlines, hotels and car rental companies appear on the invoice, backed by each supplier’s documents.
• Airline ticket: the proof is the e-ticket, with ticket number, passenger name, flight segments and fares, plus the receipt or invoice from whoever sold the ticket.
• Hotel: issues a tax invoice for the stay and any extras. When the room is billed to the company, the invoice is issued in its name; when the guest pays at check-out, they must provide the company details so the invoice is not issued in their personal name.
• Car rental: the rental company issues the rental agreement and the corresponding tax document or invoice, with mileage, fuel and fees.
• Ride-hailing and taxis: receipts from the app or the driver. Corporate accounts on ride-hailing apps usually consolidate rides in monthly reports.
• Meals and small expenses: a tax receipt, with the company’s tax ID whenever possible, according to the reimbursement or per diem policy.

Data that must be correct

Much of the rework comes from documents issued with incomplete data. Before each trip, travelers should know exactly what to ask for:

• the legal name and tax ID of the company paying the expense (in Brazil, the CNPJ, the national company registration number), which may be a branch rather than the head office;
• the billing address and an e-mail address for invoices, when the supplier asks for them;
• the traveler’s name and travel dates, to link the document to the right trip;
• the request number or cost center, when the company uses that control.

A practical tip: put these details on a standard card or file sent with the travel itinerary, so the traveler does not have to remember anything at the hotel front desk.

Centralized billing reduces paperwork

The most efficient way to organize documentation is to reduce the number of payments made by the traveler. When flights, hotels and car rentals are booked through the agency and billed to the company, most documents arrive in one place, in the name of the right company and already tagged with the cost center.

What is left for the traveler are day-to-day expenses such as meals and local transport, which can follow a per diem, reimbursement or corporate card model. The smaller this share, the lower the risk of lost receipts.

How to organize the file

One record per trip

Instead of filing loose documents by supplier, keep one record per trip: request and approval, tickets, hotel invoices, agency invoice and expense report. When a question comes up, the whole history is in one place.

Digital and standardized

Brazilian electronic invoices come as an XML file and a PDF version. Agree with your accountants on which format to keep and use a simple naming rule with date, traveler and supplier. Photos of paper receipts should be legible and taken right after the expense, because thermal paper fades over time.

Deadlines

Set a short deadline for travelers to submit receipts after returning, such as five business days, and a deadline for finance to review them. Long deadlines push the trip into the following month’s close.

Common mistakes to avoid

• hotel invoices issued in the traveler’s personal name, which then have to be cancelled and reissued;
• expenses from the same trip paid through different channels, which leads to duplicates;
• documents kept only in the employee’s e-mail or phone;
• agency invoices reviewed without the travel report at hand, which makes discrepancies hard to find;
• documentation rules that exist but are not written into the travel policy.

Frequently asked questions

Does the agency issue a tax invoice for the full ticket price?

Usually not. The agency issues a service invoice for its fee, and the ticket price is supported by the e-ticket and the agency invoice. Check the proper treatment with your accountants.

What if the hotel invoice was issued in the traveler’s personal name?

Ask the hotel to cancel it and reissue it in the company’s name as soon as possible, with the legal name and tax ID. To avoid the problem, prefer stays billed to the company.

How long should the company keep receipts?

Retention periods are set by tax law and may vary by type of document. Your company’s accountants should define the period and the storage format.
