Duplicate FBA orders

Hi all,

Any help greatly appreciated.

We have recently had a very odd problem in that Amazons API is duplicating some FBA orders when it reports back to our EPOS system… These seem to always be 2 weeks apart.

So the API gives us a sale on (say) 1st of June for £200 to Mr Smith.

Then 2 weeks later, it gives us another order, with the same order ID and product, but a different shipment ID.

This causes a second order to be recorded by our system - Amazon has 1 sale for £200, we record sales for £400.

We can’t restrict our system to ignore these as if a customer buys 2 products on FBA and they are shipped separately (so with different shipping IDs), each one needs to be imported separately so we have the full order recorded.

I appreciate we haven’t lost any stock, but obviously it’s over-recording our sales, and impacting out EPOS systems stock levels for FBA.

Anybody had a similar experience? We have made no changes to our logic for years now, so it’s almost certainly an Amazon API change, or an Amazon error.

Thanks,
