# register POS + QuickBooks Online

## How register POS syncs with QuickBooks Online

If you're using QuickBooks Online and want a smooth, integrated customer [checkout](https://abilityregister.com/encyclopedia/checkout/) experience, [register by ability business](https://abilityregister.com/encyclopedia/register-by-ability-business/) is built just for that. Here’s how syncing works and what it means for your day-to-day operations.

## What does register sync with QuickBooks Online?

When you connect register to QuickBooks Online, several key data points are shared to ensure accuracy and consistency across your business systems:

**Item List:** Products and services set up in QuickBooks Online are synced into register, so you can ring up sales using your existing inventory and product catalog.

**Customers:** Your customer list is kept in sync between register and QuickBooks Online.

**Sales Transactions:** Sales (sales receipts, invoices, returns) recorded in register are automatically posted to QuickBooks Online, ensuring your books stay up to date without double entry.

**Chart of Accounts:** During your initial configuration, you can select default accounts that align with your business needs. When a transaction is completed at register, our app automatically records entries behind the scenes—ensuring they are posted to the appropriate accounts in QuickBooks Online.

**Note:** Sales transactions (such as sales receipts, invoices, and credit memos) created in QuickBooks Online do **not** sync to Register. To view a complete customer account history, including all transactions, refer to QuickBooks Online. register provides a simple, reliable [checkout](https://abilityregister.com/encyclopedia/checkout/) experience designed for front-end sales.

This syncing keeps your data aligned across platforms and eliminates repetitive tasks.

## One-Way and Two-Way Sync Explained

Understanding how the sync works will help you manage your data effectively:

**Items – One-Way Sync (QuickBooks Online → register)**Items flow from QuickBooks Online to register. This means you manage your product list in QuickBooks Online, and register automatically pulls that data in for selling. You cannot create or edit items in register — all changes must be made in QuickBooks Online.

**Customers – Two-Way Sync (QuickBooks Online ↔ register)**Customers can be added or updated **in either system**. If you add a new customer in register during a sale, that customer will sync to QuickBooks Online. Likewise, edits made in QuickBooks Online will sync back to register.

**Sales Transactions:**Sales completed in Register are automatically synced to QuickBooks Online. For each transaction, our app generates a general journal entry that:

- Moves the **asset value** of sold items from inventory to your **Cost of Goods Sold** (COGS) account
- Records the **sales revenue** to your designated **income account**
- Applies the **payment** to either **Undeposited Funds** or a specific account you selected during setup

This seamless automation ensures your books stay accurate and eliminates the need for double entry.

Each transaction is associated with the customer who made the purchase. If no customer is selected at [checkout](https://abilityregister.com/encyclopedia/checkout/), the transaction is tied to a default customer specified during your initial configuration.

For **on account** sales (when a customer chooses to pay later), the transaction is recorded as an **invoice** and tracked under **Accounts Receivable** in QuickBooks Online.

This hybrid approach keeps your workflows flexible and in sync with accounting.

## How Syncing Helps Your Daily Workflow

The register and QuickBooks Online sync is designed to simplify your day:
