QuickBooks does not typically charge users on a per-transaction basis for standard accounting tasks such as recording income and expenses. Instead, QuickBooks offers various pricing plans and subscriptions that are based on the specific edition (QuickBooks Online, QuickBooks Desktop, or QuickBooks Self-Employed) and the level of functionality you need.

Here’s a general overview of QuickBooks pricing:

1. QuickBooks Online: QuickBooks Online offers several subscription plans with monthly fees. The pricing plans vary depending on your needs and the number of users. The plans usually include features for tracking income and expenses, invoicing, bank reconciliation, and reporting. There are often separate plans for self-employed individuals, small businesses, and larger businesses. Transaction volume is not a primary factor in determining pricing for QuickBooks Online.
2. QuickBooks Desktop: QuickBooks Desktop also offers different editions (Pro, Premier, Enterprise) with varying levels of functionality. You typically purchase a one-time license for QuickBooks Desktop software or pay an annual subscription fee. Transaction volume is not a significant factor in the pricing of QuickBooks Desktop.
3. QuickBooks Self-Employed: QuickBooks Self-Employed is designed for freelancers, contractors, and sole proprietors. It offers a monthly subscription fee and includes features for tracking income and expenses, calculating estimated taxes, and more. Again, transaction volume is not a primary pricing factor for this version.

While QuickBooks itself does not charge per transaction, there may be additional fees associated with payment processing if you use QuickBooks Payments to accept credit card payments or other payment methods. These fees are typically based on the payment method and the volume of transactions processed.

The specific pricing details for QuickBooks can change over time, and there may be promotional offers or discounts available, so it’s a good idea to visit the official QuickBooks website or contact QuickBooks customer support to get the most up-to-date pricing information based on your specific needs and location.
