Marketplace - User Guide
Overview
The Heratio Marketplace is an online buy/sell platform built for GLAM and DAM institutions (Galleries, Libraries, Archives, Museums, and Digital Asset Management). It enables institutions, artists, collectors, and estates to list items for sale, while buyers can purchase through three distinct sale types: Fixed Price, Auction, and Make an Offer.
The marketplace supports all five GLAM/DAM sectors, each with sector-specific categories tailored to the types of items that institutions and individuals typically sell.

Buying (Fixed Price)
On a fixed-price listing, click "Buy Now"
You will be directed to the purchase flow at /marketplace/buy/:slug
Review the order summary:
Item price
Shipping cost (domestic or international)
VAT (included in price)
Grand total
Proceed to payment via the configured payment gateway (e.g., PayFast)
After payment, the listing is marked as Sold and a transaction record is created
You will receive an order confirmation
Note: You must be logged in to make a purchase. Guest users will be prompted to log in first.
Making an Offer
On listings with "Make an Offer" available (offer-only or fixed-price listings with offers enabled), click "Make an Offer"
You are taken to the offer form at /marketplace/offer/:slug
Enter your offer amount
If the seller has set a minimum offer, your amount must meet or exceed it
Optionally add a message to the seller explaining your offer
Submit the offer
The offer status flow:
If the seller sends a counter-offer, you can:
Accept the counter-offer (proceeds to payment at the counter amount)
Withdraw your offer (cancels the negotiation)
Offers expire after the configured period (default: 7 days)
You can only have one pending offer per listing at a time
Bidding at Auction
On an auction listing, click "Place Bid" to open the bid form at /marketplace/bid/:slug
The form displays:
Current bid (or starting bid if no bids yet)
Minimum bid (current bid + bid increment)
Bid count and time remaining
Enter your bid amount (must meet or exceed the minimum bid)
Optionally set a maximum bid for proxy/auto bidding:
The system will automatically bid on your behalf up to your maximum
Auto bids are placed at the minimum increment above the previous bid
Your maximum bid is kept private
Submit your bid
Reserve Price
Some auctions have a reserve price set by the seller
If the highest bid does not meet the reserve when the auction ends, the item is not sold
The reserve price is not displayed, but you may see a "Reserve not yet met" indicator
Anti-Sniping Protection
If a bid is placed in the final minutes of an auction (default: last 5 minutes), the auction end time is automatically extended
Extensions add the configured number of minutes (default: 5 minutes)
A maximum of 10 extensions are allowed per auction
Buy Now in Auctions
Some auctions offer a "Buy Now" option at a set price
Click "Buy Now" to purchase immediately at the Buy Now price, ending the auction
This option may be available even while bidding is active
Monitoring Your Bids
Navigate to /marketplace/my/bids to view all your active and past bids
Each entry shows the listing, your bid amount, current highest bid, and auction status
You will see whether your bid is currently winning or has been outbid
Tip: Set a proxy bid (maximum bid) so you do not need to monitor the auction constantly. The system bids for you automatically.
