If you are migrating to Breezing from another subledger or starting your accounting partway through a wallet’s history, you do not need to pull in years of irrelevant historical transactions. Instead, you can simply inject an Opening Balance for a specific date (e.g., Jan 1st).

​
Method 1: Adding Opening Balances Manually

Best if you only have a few assets to start with.
  1. Navigate to the Wallets page and select the wallet you want to add balances to.
  2. Click Add Transaction.
  3. Fill out the transaction details:
    • Hash/ID: Type something clear like Opening Balance 2024.
    • Date: Select the start date of your accounting period (e.g., Jan 1, 2024).
    • Direction: Inbound.
    • Asset: The token ticker (e.g., ETH).
    • Amount: The exact token amount held on that date (e.g., 2.0).
    • FIAT Amount: Enter the exact historical fiat cost basis from your accounting system (do not rely on live spot prices for opening balances).
    • Type: Write Opening Balance.
  4. Click Add. The balance will immediately reflect in your wallet.

​
Method 2: Bulk Upload via CSV

Best if you have dozens of tokens or multiple wallets to initialize.
  1. On the Wallets page, click the wallet and select Upload CSV.
  2. Download the Breezing CSV template.
  3. Fill out the template rows for each asset you hold:
    • Date: 01/01/2024 (Ensure Excel formatting matches the template!)
    • Hash: Opening Balance 2024
    • Direction: IN
    • Asset: USDC, ETH, etc.
    • Amount: The token balance.
    • Amount FIAT: Your historical cost basis from your general ledger.
    • Type: Opening Balance
  4. Leave the fee columns blank.
  5. Save the CSV and upload it to Breezing.
Your wallet will instantly populate with all the correct opening balances and historical cost basis figures, giving you a clean slate to start calculating from!
All right, guys. So, in this video, we’re going to show you how to add opening balance. It’s pretty simple. Go ahead and click on the wallet you want to add an opening balance for. Let’s call it ops wallet. Just come down here. Go ahead and hit add transaction. You’re going to add add transaction here. You’re going to write things like opening balance 2024, let’s say. And I’m going to call this one ETH. And then I’m going to select, let’s say, the opening balance starting on January 1st, 2024. A second here. I’m going to select pretty much direction inbound the token. I’m gonna do ETH amount. I’ll do two ETH. I’m going to say they’re worth maybe 3500. Again, this is the amount that you have on January 1st, 2024. And it’s also this is the fiat amount that you typically have in your accounting system, not the one maybe in your other subleddger or where else you’re using. Choose kind of like the fee token. Just call it ETH. You can leave these as zero. And then type. You just kind of write opening balances. One second. And then once you’re done, go ahead and click add. and it’ll be added just right over here. And then you can kind of see here Ethereum you can update the token balance and it’ll be reflected e that token balance is now changed. If you have many let’s say um opening balance you need to book the best way to do is do it via CSV. Go ahead and click here upload CSV download it. Go ahead and open it up. Got to bring it over here. Again it’s kind of the same logic that you’re doing. You’re pretty much just selecting the date. Again you’re going let’s say 2024. Oh 01 01 you’re calling this one opening balance 2024 inbound ETH ETH again do two then here I would do 3500 which is the fiat amount you can leave these ones as blank and then kind of put this one as opening balance then go ahead and kill that like that you need one line you can add multiple now so you can go ahead and say okay now my next one I’m going to do USDC I had like 5,000 USDC and maybe my accounts in 5,000. So yeah, you kind of just do them all the way down pretty much until you have what you need. And then you just go ahead and uh make sure the uh the date also formats. So make sure you got this date format here. So go ahead and click that. Go ahead and pretty much just format the cells, throw in the date, go ahead and save the CSV, and then just upload away. There you go. It’s done. Let me know if that helps. Looking forward to kind of working with you more. Thanks.
