It's slow to sync data or calculate my demand analysis. How can I speed this up?

It can take anywhere between a few seconds, or a few hours to re-sync your data and recalculate your order plans. It depends a lot on the amount of data, number of SKUs and how many BOMs you have.

This can be set to run overnight, in settings, you can select your 'Automatic update frequency' so that it's updated up to several times per week automatically. This way your order suggestions will always be accurate and up to date whenever you log in.
