Keepa is the reference for Amazon price history. But depending on your use case — multi-source sourcing rather than tracking a single product — an alternative or complement may fit better.
What Keepa does, and what it doesn't
Keepa excels at one specific thing: showing how an ASIN's price and BSR evolve over time. It's a verification tool, not a discovery one — it doesn't compare your suppliers against each other and doesn't calculate your net margin after fees.
What a good tracking/sourcing tool needs to do
- Reliable history of price and sales rank
- Multi-source comparison, not just multi-history
- Real margin calculation (fees, VAT, customs) rather than a gross gap
- Alerts when a net gap becomes attractive again
The criterion that changes everything: net margin, not gross price
A price history tells you *what happened* on Amazon. It says nothing about the real purchase cost at your supplier, nor the fees standing between the displayed price and the margin you actually keep. A complete sourcing tool needs to combine price history and multi-supplier purchase price to judge whether a gap is genuinely usable today.
How to choose
- Need to check a product before buying → Keepa remains relevant for the history.
- Need to find gaps across a whole catalogue → a multi-source comparison tool with net calculation fits better.
- Need both → combining the two remains the best option for now.
In summary
Keepa answers a specific question (a product's history) but not the question of sourcing at scale. ArbitragePro+ positions itself on that second question: continuously comparing hundreds of sources and showing only gaps that are already net profitable.
