Mercury Books vs QuickBooks: what free through 2026 covers, and what it leaves out

Mercury Books costs $0 until 2027 and $35 a month after, against $38 to $340 for QuickBooks

From 2027 Mercury Books costs $420 a year, and QuickBooks costs $456 to $4,080 a year. QuickBooks also runs 50% off for the first 3 months, which this table leaves out.

Mercury Books keeps the books inside the bank account, and its AI asks before it changes anything

• It syncs every Mercury checking, savings and credit account, including closed accounts, and reconciles them continuously because they live in the same system as the books.
• It categorizes with AI, similarity matching and rules you define, on a double-entry ledger with cash or accrual basis.
• It connects other banks and cards through Plaid, plus Stripe, PayPal and Gusto, and it pulls in Mercury invoices and bills.
• It produces a Profit and Loss, Balance Sheet, Cash Flow and General Ledger that you can filter, drill into and export.
• Command, its AI assistant, answers questions and does bulk work such as recategorizing transactions and drafting journal entries. Launch coverage says each action needs your confirmation first.

The design choice is that banking data and books are one dataset, so Mercury's own accounts reconcile as transactions land instead of when you import a file.

What Mercury Books leaves out today, from Mercury's own support pages

Moving from QuickBooks is a cutover on a date you choose, not an import

1. 1

   Step 1: Pick a cutover date. The first day of a month is easiest, because reconciliation in Books runs on monthly windows.

2. 2

   Step 2: Close your last period in QuickBooks. Export the chart of accounts as a CSV, a trial balance as of the day before the cutover, and any reports you want to keep.

3. 3

   Step 3: In Books, import the chart of accounts during setup and set the entry start date under Settings > Books Details.

4. 4

   Step 4: Connect your Mercury accounts, other banks and cards through Plaid, and any Stripe, PayPal or Gusto account.

5. 5

   Step 5: Post one journal entry dated the day before the start date with your opening balances, then reconcile the first month.

Mercury suggests keeping QuickBooks until the first month reconciles, and says you will code every transaction twice during that month. Earlier periods stay in QuickBooks, so keep a full-history export before you cancel. To bring the whole history across instead, see how to switch from QuickBooks.

Choose Mercury Books if Mercury is your only bank; choose QuickBooks if you bank elsewhere or need history

• Mercury Books is better on price for 2026, on books that reconcile as transactions land, and on accountant seats, which have no cap.
• QuickBooks is better when you bank outside Mercury, when you need your past years in the same file, and when you want the inventory management, project profitability and workflow tools Intuit lists on its Plus and Advanced plans.
• QuickBooks is also the tool your accountant may already use. Ask before you switch, because Mercury's advisors join through your Mercury account.
• Mercury Books is two weeks old. Its price already changes on January 1, 2027, so budget for $35 a month and check mercury.com/books before you count on the free year.
