Mission trips can be one of the most meaningful things your church does all year—but behind every trip is a pile of logistics, and the financial side is often the trickiest to manage.

Between designated donations, participant payments, and receipts from every gas station between here and Honduras, it’s easy for things to get messy fast. But with a little prep and a few smart systems, your team can stay organized and make sure the funds are used the way they were intended.

If your church is looking for practical help with church financial management during missions season, this guide is for you.

1. Build a Budget That Includes Wiggle Room

Start by listing out every expected cost—airfare, transportation, lodging, meals, supplies, insurance, and anything else your team might need. Once that’s mapped out, build in a cushion for surprises. There’s always something you didn’t plan for, whether it’s baggage fees or a rental van breakdown. A small buffer (even 10%) goes a long way.

Having this budget written out from the beginning gives your church a clear picture of what the trip will actually cost—and helps you explain the financial needs to donors and participants.

2. Keep Mission Trip Donations in a Separate Bucket

Donations that come in for the mission trip should be treated as designated or restricted funds. That means they aren’t part of your general church budget, and they need to be used only for the trip.

It’s not just best practice—it’s also about honoring what your donors intended. If someone gave toward the mission trip, those dollars shouldn’t quietly disappear into the general fund after the team comes home. Keep everything separate in your church bookkeeping system, and label it clearly so you can track what’s been received and what’s been spent.

3. Track Donations by Donor

For every mission trip gift, make sure you’re recording the donor’s name, the amount, and that it was given specifically for the trip. This is helpful for your internal tracking, but it’s also essential when it comes time to issue year-end giving statements.

Even if your church doesn’t have a full donor management platform, this can be tracked inside QuickBooks Online for churches using classes or tags—or even a well-organized spreadsheet if you’re just getting started with faith-based bookkeeping.

4. Be Clear About What Participants Are Paying

If participants are covering part (or all) of their trip cost, make sure expectations are clear up front. How much is due, by when, and what does that payment actually cover?

We’ve seen plenty of confusion over whether a payment “counts” as a donation or just a personal expense. In most cases, if someone is covering the cost of their own travel and meals, it’s not tax-deductible—but if they’re contributing toward the trip as a whole, it might be. Check with a tax advisor or CPA familiar with bookkeeping for churches if you’re unsure.

5. Save Every Receipt

Yes, even the tiny ones. Every gas fill-up, baggage fee, and Chick-fil-A lunch should be saved and recorded. If it was paid with mission trip funds, you’ll want a receipt for it.

You don’t need a shoebox full of paper, though. We recommend using a receipt capture app like Dext or even a shared Google Drive folder where team leaders can snap photos of receipts and upload them while on the trip.

6. Stick to the Purpose of the Funds

This one’s important: if someone donates toward the mission trip, those funds need to be spent on the mission trip. If there’s money left over, it should stay designated for future trips or a related missions purpose.

The only exception? If donors have explicitly given permission to use leftover funds elsewhere. But unless that’s been clearly communicated, don’t move those dollars into the general fund or spend them on unrelated expenses.

7. Make Giving Statements Easy

When year-end rolls around, be ready to include mission trip donations in your giving statements. Donors appreciate having a record of their contributions, especially if they gave toward someone else’s participation or supported the trip directly.

This is one more reason why it’s worth tracking everything clearly as you go—so you’re not stuck in December trying to piece together who gave what back in June.

Wrapping Up

Mission trips are full of moving pieces—flights to book, supplies to buy, donations to track, and receipts to manage. When the financial side is handled well, it frees your team to focus on the real purpose of the trip: ministry. Clear records, designated funds, and good communication aren’t just best practices—they’re what make it possible to run the trip with integrity and confidence from start to finish.
