My customer paid there invoice through quickbooks online. i usually have a check mailed directly to me. i cant find the payment

I'll share information about invoice payments made through QuickBooks Online, @affordableaquari.

If the money is not in the Undeposited Funds account, it may mean that the deposit hasn't appeared in QuickBooks Online yet.

Bank deposits for credit card payments take 1-2 business days, whereas bank transfers (ACH) take 2-7 business days.

When your bank accepts the transactions, it will determine the deposit date. In this article, you can find additional information: QuickBooks Payments Deposits FAQ.

Meanwhile, you can track your transactions through the Merchant Service Center:

1. Log in to your Merchant Service account.
2. Click Activity & Reports and select Deposits.
3. Use the Date fields to filter the data.

You can also check if the payment is in undeposited funds account. Unless you physically deposit the fund to your actual bank, the Undeposited Funds account records payments in QuickBooks. Most of the time, banks aggregate all of your deposits into a single transaction. After you have your deposit slip and know which payments your bank combined, you can do the same in QuickBooks.

Additionally, if you want to utilize instant deposits, you'll have the ability to swiftly transfer funds into your bank account within less than 30 minutes. Then, you have the option to set up automatic scheduling for instant deposits. Note that you need a QuickBooks Payments account to get instant deposits.

For a one-time instant deposit, you can get your money on the same day if you request 3:00 PM PT. After that, it will be processed on the next day. You can request a deposit anytime.

You have the flexibility to utilize Instant Deposit up to a maximum of 5 times per day. Whether you wish to deposit as little as $1 or as much as $25,000 per day, the choice is yours. It's important to note that your limit resets daily.
