Features
One catalog. Every platform.
Prices always in sync.
You updated your website prices but forgot Amazon. Or you updated both, but with different spreadsheets that were slightly out of sync. Or you skipped Amazon entirely because managing two sets of pricing is more work than the revenue justifies. PriceTool calculates platform-specific prices from a single source and delivers upload-ready files for each platform.

Not because they do not want to sell on Amazon. Not because they lack inventory. Because managing pricing across multiple platforms manually does not scale.
Here is what multi-platform pricing looks like without a managed service:
- You have a Harken price file with 2,000 products
- You apply your website markup formula in one spreadsheet
- You apply a different Amazon markup formula in another spreadsheet
- You export a file for your website. You export a different file for Amazon.
- A week later, Harken changes costs on 50 products. You update the website spreadsheet. You forget the Amazon spreadsheet until a customer complains about a price discrepancy.
Multiply this by every supplier and three platforms. The math does not work. So most marine retailers either avoid marketplaces entirely — leaving significant revenue on the table — or they sell on marketplaces with stale pricing and accept the margin erosion.
Neither option is acceptable.
Different platforms. Different economics. Different prices.
Amazon charges referral fees. eBay charges final value fees. Your own website has payment processing costs but no marketplace commission. Your margins are different on every platform — so your pricing should be too.
Per-Platform Markup
Set different markup percentages for each platform. Your website might use a 40% markup on Harken wholesale costs. Amazon might use 48% to account for referral fees. eBay might use 45%. All calculated from the same supplier cost, all updated when that cost changes.
Per-Platform Rounding
Your website prices might end in .95. Amazon prices might end in .99. PriceTool applies the rounding rule you choose for each platform independently — consistent, automatic, every product.
Per-Platform Product Selection
Not every product needs to be on every platform. Create platform-specific assortments from your master catalog. Sell Harken blocks on all three platforms but keep specialty Sta-Lok terminals on your website only.
Per-Platform Metadata
Product titles, descriptions, and categories can be customized per platform. Amazon product titles follow different conventions than your website. PriceTool manages both from a single master record.
Three-Tier Resolution
When PriceTool generates output for a specific platform, it uses a priority system for every field:
- Platform-specific override (highest priority) — what you set for this platform specifically
- Seller customization — what you set across all channels
- Supplier default (fallback) — what the supplier provided
This means your customizations persist through every supplier update. If you wrote a better product description for Amazon, it will never be overwritten by the next Harken file import.
A supplier cost changes. Every platform updates. Simultaneously.
When Ronstan raises their wholesale costs by 8%, PriceTool recalculates:
- Your website price for every affected Ronstan product
- Your Amazon price for every affected Ronstan product
- Your eBay price for every affected Ronstan product
- All variant prices derived from those products
All in the same processing run. No platform forgotten. No two-month gap between a cost increase and a price update.
Pricing cascade — one cost change, three platforms:
Ronstan wholesale cost: $25.00 → $27.00 (+8%)
Website (40% markup):
$35.00 → $37.80
Amazon (48% markup):
$37.00 → $39.96 → $39.99 (rounded to .99)
eBay (45% markup):
$36.25 → $39.15 (rounded to .95)
Every price recalculated from the same cost change. Every platform's rules applied independently. Every output file ready to upload.
Where your data goes.
PriceTool generates upload-ready files formatted to each platform's exact specification.

Important: PriceTool's core pricing engine works today regardless of your sales platform. The engine that reads supplier files, normalizes data, calculates prices, enforces MAP/MSRP, and generates change reports is production-ready. Platform exporters determine the format of the final output file. If your platform is not yet supported, PriceTool can generate a standardized flat CSV that you can map to your platform's import format.
You have the inventory. You have the catalog. You do not have the bandwidth.
Marine retailers who sell only on their own website are leaving marketplace revenue uncaptured. The sellers we researched with 6,000 to 100,000+ SKUs have the product depth to compete on Amazon and eBay — but the pricing complexity of multi-platform management keeps them on the sidelines.
The calculation is straightforward:
- A marine retailer with 10,000 SKUs selling only on their website
- Add Amazon as a second channel
- Even if only 20% of the catalog is competitive on Amazon (2,000 products)
- At an average selling price of $50 and even modest volume
That is revenue that requires no additional inventory, no additional warehouse space, and no additional product sourcing. The only barrier is pricing management — and that is exactly what PriceTool eliminates.
