Bills maximum 1000 row , i want to increase this limit

Thanks for checking in with us, sibrahim-getduka.

The option to increase the bill's row limit is unavailable in QuickBooks Online (QBO). We can only adjust the rows by exporting them to Excel and modify the data from there. If you export data like report to Excel, we can get more data:

• Maximum of 1024 columns displayed (this is an Excel limit)
• Maximum 400,000 cells* with data
• Maximum 10 MB worth of data

Also, QBO doesn't have a limit on entries and transactions. The program can support as many line items on a sales form. However, there are chances that you'll experience minor performance issues as the number of lines increases. To avoid this, we can split it into multiple transactions. This way, the QuickBooks can easily load/send your transactions and help keep the program running at peak performance when we're processing a large volume. 

Also, there are various things you can do to ensure that you'll get the most out of your QuickBooks experience. Please check the pointers below:

• Ensure your web browser is up to date.
• Check to see if there are critical performance updates for your operating system.
• Run an internet speed test.
