Hey Product Hunt! 👋 I'm the maker of BoxSplit. I built this tool because Amazon's Inbound Placement Service fees were eating into my FBA margins, and I couldn't find a free, simple way to calculate the optimal shipment split. Instead of guessing whether to ship to a single destination or split across multiple fulfillment centers, I wrote a Python script that uses a bin-packing algorithm to find the mathematically cheapest way to split your shipments based on box dimensions and weight tiers. I turned this script into a completely free, no-signup web tool so other sellers could use it too. No paywalls, no data collection, just the math to help you protect your margins. It supports US, UK, DE, FR, CA, AU, and JP marketplaces. You can even upload a CSV with hundreds of SKUs for instant optimization. I'd love to hear your feedback! What features would make this more useful for your workflow? Have you tried optimizing your FBA splits before? Thanks for checking it out! 📦
