Stop Entering Expenses Twice: SplitterUp's Bank Import

Here's the thing about logging expenses: you already have all of them. Every purchase you made last weekend — the Airbnb, the group dinner, the tank of gas — is sitting in your bank app right now, with the exact amount and the exact date. Your bank recorded it the moment you paid.

So why do expense splitting apps make you type it all in again?

That's the friction point that kills most people's tracking habits. It's not that they forget to split expenses. It's that re-entering transactions you've already seen once — from your bank app into your expense app — is tedious enough that it stops happening. You tell yourself you'll do it later. Later doesn't come. The trip ends, the balances are murky, and settling up becomes a rough estimate instead of an actual number.

The Problem Isn't Forgetting. It's Double Entry.

Most expense tracking advice focuses on the wrong thing. "Log it immediately," people say. "Don't let expenses pile up." That's reasonable advice, but it misses the root cause.

The reason people don't log expenses isn't a discipline problem. It's that logging an expense takes real effort: open the app, tap to add, type in the merchant name (which you now have to recall from memory), enter the amount, select the right group, confirm. Meanwhile, your bank already did all of that automatically. The merchant name, the exact dollar amount, the date — it's already there.

Asking someone to do that data entry twice is a reasonable thing to ask exactly once. After that, the habit breaks.

What Bank Import Actually Does

Bank Import connects SplitterUp to your bank account so your real transactions show up inside the app. You browse them, select the ones you want to split, and import them. Each transaction becomes a pre-filled expense — merchant name, amount, date already filled in — ready to assign to a group and split.

That's it. No re-typing. No trying to remember whether dinner was $67 or $72. The number is right because it came from your bank.

The connection works through Teller, which supports over 7,000 US banks. If you have a bank account in the US, it almost certainly works.

One Small Detail That Makes a Big Difference

If you've ever looked at your bank statement closely, you know the merchant names are often unusable. "POS DEBIT 4829 THAI ORCHID #127" is technically correct, but it's not what you'd put in an expense tracker. "AMZN Mktp US*K39Z" is Amazon, but good luck deciphering it at a glance.

SplitterUp cleans these up automatically. That same "POS DEBIT 4829 THAI ORCHID #127" becomes "Thai Orchid" in the app. The cryptic bank codes get stripped, and what remains is a readable name you'd actually recognize. It sounds like a small thing, but it's the difference between an import that feels polished and one that just moves the mess from one app to another.

Batch Import for the Real World

Sometimes you want to import one expense. More often, you're back from a weekend trip and you have seven transactions that need to be split with the same group of people.

You can select all of them at once. One flow, one import, each transaction turned into its own pre-filled expense. You assign them to the right group, review any details you want to adjust, and you're done. What used to be ten minutes of manual entry takes about thirty seconds.

This is where the feature really pays off. Batch import isn't just a convenience — it makes splitting an entire trip's worth of expenses realistic without dreading the process.

On Privacy and Security

Connecting any app to your bank account requires some trust, so it's worth being clear about what's actually happening.

The connection is read-only. SplitterUp can see your transactions. It cannot move money, make payments, or touch your account in any way. That's not a policy — it's a technical constraint of how the connection works.

Your bank credentials go directly to your bank through Teller's encrypted connection. SplitterUp never sees your username or password, and they're never stored anywhere in the app.

If you disconnect a bank account, all imported transaction data from that account is permanently deleted. Not archived, not retained — gone. And if you delete your SplitterUp account entirely, everything goes with it.

You can link multiple accounts if you want — a checking account and a credit card, for example — and manage them all from one place. Connect, sync on demand, or disconnect anytime.

Who This Is For

Bank Import isn't for people who religiously log every expense the moment it happens. If that's you, you've already solved the problem and you don't need this.

It's for everyone else. People who split expenses regularly — roommates, couples, travel groups, friends who grab dinner once a week — but find that manual entry is just friction enough to skip. The moment you're back from a trip and you have to recall six days of expenses from memory, the system breaks down.

Bank Import works because the data is already accurate. You're not guessing at amounts or spellings or dates. You're just pointing at the transactions your bank already recorded and saying: split that one.

It's a small shift in workflow that makes a surprisingly large difference in whether the habit actually sticks.
