Small to medium bundles - (e.g. 20–30 documents) typically generate quite quickly—often within seconds to a couple of minutes.
Larger bundles—those containing hundreds or thousands of documents—can take longer to generate. The system automatically handles indexing, pagination, sectioning, and hyperlinking, which adds to the processing time.
You don’t need to stay on the page while the bundle is generating as the bundle is generating in the cloud and will pop up on the screen once generated. You can even log out or turn off your computer as Bundledocs will also send you an email notification once the bundle is ready to download.
NOTE: A bundle limit of 5gb exists for each bundle on Bundledocs, and if your bundle is close to this limit it can take longer to generate.
To check your bundle size:
1. Go to 
Generate & Customise Bundle which is the 3rd icon located at the top left of your bundle.
2. Click Generate Stats, which is the i icon at the bottom left of Generate and Customise Bundle.
