@Dreamscape-Studio and @aerides this is exactly what I did. I was not a handmaker but a small batch manufacturer, and every product was both assembled and created. My umbrella Company (LLC; manufacturer) invoiced my Store (DBA; sales).
Regardless, it’s this part that torpedoes ALL Sellers using FBA:
Your stickers, your outer packaging, your printing, your internal packaging, your individual shipping packaging, your shipment packaging, your (compliant!) inserts, your QA labor, your shipping labor, your shipping fees, and probably more–NONE OF THAT is reimbursed to Sellers, for Amazon’s errors.
So it almost seems like all FBA Sellers (who are concerned about reimbursement values) need to consider becoming brand registered (so your ASINs and private label/small batch/handmade products are yours only) and then invoicing yourself for THE COMPLETE PACKAGE that is shipped to FBA. All costs looped into that invoice and per-item cost.
Am I seeing this clearly?
