Amazon Profitability Software
Looking for Amazon profitability software that shows contribution after fees and ads? Spillmark imports your reports and shows profit by channel.
- Profit after Amazon fees, product cost and ads
- Amazon, Meta and Shopify side by side
- Holdouts when you need caused Meta sales

What you get
Dashboard ($19/mo) covers report imports from Seller Central, Amazon Ads, Meta and Shopify, and profit by channel with the math behind every number.
Starter adds geo holdout tests when Meta credit is not enough. You approve every pause.
Built by a seller
Built by an Amazon seller, tested on our own brand. The dashboard shows the math behind every number so you can check the work.
When this fits
Use it when Seller Central and ad consoles disagree, or when TACoS looks fine but cash does not. It is not a keyword-harvesting PPC suite.
Questions
- Is this Sellerboard?
- Spillmark focuses on Meta → Amazon measurement and contribution profit. It is not a keyword-harvesting PPC suite or reimbursement tool.
- Do I have to run a holdout?
- No. Dashboard stands alone. Holdouts are on Starter and Growth when you want caused sales.
- Can I cancel?
- Yes. Cancel anytime from Settings. Cancel during the trial and you are not charged.
