Verified valuations that make every listing more credible.
Ownich brings certified appraisal data into your marketplace. Every listing with an Ownich certificate shows a verified valuation — giving buyers a trusted price reference, helping sellers justify their asking price and giving your platform the data to build authoritative market price indices.
Why appraisal matters for marketplaces
Price uncertainty is the biggest barrier to completing a transaction.
On most marketplaces, buyers and sellers negotiate blind. The buyer doesn't know if the asking price is fair. The seller doesn't know if they're leaving money on the table. The result is abandoned transactions, lowball offers and disputes that damage your platform's reputation.
Ownich solves this by surfacing certified appraisal data from the item's ownership certificate directly on the listing. Buyers see a verified valuation alongside the asking price. Sellers can justify their price with evidence. And your marketplace gets the data to build category price guides that attract serious buyers and sellers.

How it works
Appraisal data from certificate to listing
Ownich integrates with your marketplace platform to surface verified valuations on every listing that carries an Ownich certificate — without changing your core buying and selling flow.
Seller lists with their certificate
When a seller lists an item, they attach their Ownich certificate. The listing automatically displays the verified valuation from the certificate alongside the asking price.
Buyer sees the full price history
Buyers can view the item's original purchase price, every appraisal update and how the current asking price compares — all from the certificate, before they pay.
Transaction completes with confidence
With a certified valuation on the listing, buyers are more likely to complete the transaction. Fewer abandoned carts, fewer disputes, higher conversion rates.
Marketplace builds price intelligence
Every transaction feeds your marketplace's price index. Aggregate appraisal and transfer data to build category price guides and market trend reports.
Benefits
What verified appraisals do for your marketplace
Certified valuations on listings reduce friction, increase buyer confidence and give your platform the data to build authoritative market intelligence products.
Higher transaction completion rates
Buyers with a certified valuation to reference are more likely to complete a purchase. Verified listings convert better than unverified ones — consistently.
Fewer pricing disputes
A certified valuation gives both parties a neutral reference point. Fewer disputes, faster negotiations and less load on your support team.
Stronger seller positioning
Sellers with a verified appraisal on their certificate can justify their asking price with evidence — reducing lowball offers and time-wasting negotiations.
Trusted price reference for buyers
A certified valuation removes the guesswork. Buyers know they're paying a fair price — and are more likely to return to your marketplace for future purchases.
Platform-level price analytics
Aggregate appraisal and transfer data across your marketplace to build category price indices, trend reports and market intelligence products that attract serious traders.
Reduce fraud and misrepresentation
A certified valuation from the original brand or retailer is harder to fake than a seller's own estimate. Appraisal records add another layer of trust to every listing.
