One of the benefits of Tiller is that you can link multiple financial accounts to one or more Tiller Sheets. However, having transactions from multiple accounts funneling into your Transactions sheet can get a little confusing if you use one account to pay off a balance or transfer money to another account, and both are linked to the same Tiller spreadsheet.
So how do we manage this without double counting that money? Usually, these kinds of transactions shouldn't be classified as spending or income. Instead they should use a "Transfer" category type.

What is a transfer?
A transfer is any movement of money between two accounts you have linked in Tiller. Common examples include:
Paying a credit card bill from your checking account
Moving money from checking to savings
Withdrawing cash from an ATM
Being reimbursed by your employer
When a transfer happens, it creates two transactions in your Transactions sheet:
A negative transaction (money leaving one account)
A positive transaction (money entering another account)
When you categorize both as a Transfer type, they cancel each other out by summing to $0, so your budget and cash flow calculations stay accurate.
Understanding the Transfer category type
The Categories sheet includes a default Transfer category out of the box. Any category assigned the Transfer type will be excluded from budget dashboards and cash flow calculations.
You can create additional Transfer categories to track specific types of transfers more granularly. To add a new Transfer category:
Open your Categories sheet
Type a new category name at the bottom of the list (e.g. Credit Card Payment, ATM Withdrawal, Reimbursement)
Set the Type column to Transfer
Assign it to a Group (e.g. Transfer)
Important: Always add new categories at the bottom of the list or type over existing ones. Do not insert rows in the middle as this can break dropdown menus and formulas in your Transactions sheet.
Transfer Category Type Use Cases
Paying a credit card bill
When you pay your credit card balance from a checking account, both transactions appear in your sheet:
A negative amount leaving your checking account
A positive amount entering your credit card account
Categorize both as a Transfer type category such as Credit Card Payment. This prevents the payment from being counted as spending twice.
Note: If you're actively paying down credit card debt and want to budget for those payments, treat them as an Expense instead. See When to use Expense instead of Transfer below.
Tracking cash withdrawals
When you withdraw cash from an ATM:
Categorize the ATM withdrawal transaction from your bank as a Transfer (e.g. ATM Withdrawal)
Manually add each cash purchase to your Transactions sheet and categorize it as the appropriate spending category (e.g. Groceries, Restaurants)
This way your cash spending shows up in your budget without double-counting the withdrawal itself.
Tracking reimbursements and refunds
Reimbursements: Create a Reimbursement Transfer category. Categorize each reimbursable purchase as Reimbursement, and when the reimbursement deposit arrives, categorize that as Reimbursement too. The two transactions cancel out.
Refunds: If you return an item, categorize both the original payment and the credit as a Refund Transfer category. Again, the two transactions cancel each other out to $0.
When to use Expense instead of Transfer
There are some cases where you might not want to use the transfer category for transactions where both accounts are linked because you want the outflowing transactions to show up on your budget.
Mortgage and asset loan payments
Mortgages and car loans are debts, but once they're paid off they're considered an asset. Even though these are technically transfers (money moving between accounts), we often also want to account for these payments as expenses in our budget.
Savings and investment contributions
If you want to budget for how much you're saving or investing each month, treat those contributions as an Expense type category (e.g. IRA Contribution, Emergency Fund). This ensures your savings goals show up on your budget dashboard.
How to Budget for Transfers
When you want a transfer to appear in your budget as an expense, but both the debit and credit transaction appear in your sheet, use this approach to avoid counting it as income:
Create a category for the debit transaction (money leaving) and set it as Expense type, e.g. Mortgage Payment, IRA Contribution
Create a separate category for the credit transaction (money entering the loan or investment account) and set it as Income type
On the Categories sheet, set Hide from Reports to Hide for the income category
Hiding the credit category from reports ensures that it's not being counted as actual income in your budget, and it won't affect your planned or actual cash flow, but allows you to categorize both transactions without having a transfer that doesn't ever sum up to $0.
Additional Advice
There really is no "right" way to use transfers and whether or not you need or want to budget for them is up to you and should be based on your financial situation.
