How to set up multiple feeds to sum up quantity ?
This guide shows how to configure multiple feeds so their quantity values combine into a single total.
Key rule to remember:
- The first feed must use the Overwrite existing quantity option (the default) in the Quantity field’s smart settings.

- All additional feeds must be set to Add/Deduct with existing quantity (+)

- Enable a daily schedule for all three feeds. Set the first feed to run earliest, with the other two running afterward in sequence.
Following this ensures the total quantity is calculated correctly without overwriting or duplicating counts.
Why This Matters
If additional feeds stay on overwrite existing quantity, they will overwrite the first feed’s values, causing total quantities to be wrong.
Using Add/Deduct with existing quantity for following feed ensures each new feed contributes correctly to the final sum.
