How do I set up the online version to continue with my desktop PO, bill and invoice numbers?

You can enable the Custom Transaction Numbers feature in QuickBooks Online (QBO), afritze. This feature lets you apply the sales transaction numbers you want. I'll share further details on this matter.

When generating invoices or purchase orders, the system automatically designates transaction numbers to them. If you want to use a different sequence number, kindly turn on the Custom Transaction Numbers to carry forward the numbers from QuickBooks Desktop (QBDT). Here's how:

1. Click the Gear icon, then tap the  Sales menu.
2. Select the Sales form content tab.
3. Turn on the Custom transaction numbers option.
4. Tap Save, then Done.

Once done, you can enter the last number used in your QBDT when creating a purchase order or invoice to maintain the sequential order in your online version.

However, every time you create a bill, you'll need to enter the bill number manually. There's no option to continue its sequence number automatically.

You can also run reports to track your business's finances. Then, you can customize and memorize them to personalize the data and save the configuration settings.
