Configuring Product Auction For Shopify

The configuration of Product Auction is very simple and divided into 05 sections:

Auction Configuration
Widget Configuration
Mail Configuration
Label Configuration
Design Configuration
SMTP Configuration

General Configuration:

Enter your email and upload your shop logo in this section. The shop logo’s image dimension should be 197 x 52. Extensions Supported: jpg, jpeg, png, JPG, JPEG, PNG.

Auction Configuration:

Configure the auction/bidding configurations like enable/disable start auction automatically, send automatic emails to the bidders to notify their loss.

Restrict consecutive bidding

We have introduced a new feature that allows the Admin to restrict consecutive bidding in auctions. Another bidder must outbid a bidder before they can place a new bid.

Bidders are not allowed to place consecutive bids unless they have been outbid first.

For this kindly go to the Product Auction Admin panel >> Configuration >> Auction Configuration

Highlight Current Bid on Collection & Product Page

By enabling this configuration, you can customize the color of the “Current Bid” displayed on the collection and product pages based on the customer’s participation status in the auction.

You can configure separate colors for:

Customers currently leading the auction
Customers who have participated in the auction
Customers who have not yet participated in the auction

This feature helps customers quickly identify their bidding status and improves the overall auction experience on the storefront.

This is how it appears on the collection page of your store:

This is how it appears on the product page of your store:

Confirmation When Customer Places a Bid

Enable this configuration to display a confirmation pop-up whenever a customer places a bid on an auction product.

This confirmation message helps customers review and confirm their bid before it is submitted, reducing the chances of accidental bidding.

Enter Label

You can also configure a custom label/message for the bid confirmation pop-up according to your store requirements and auction workflow.

This is how the confirmation pop-up appears once a bid is placed.

Amount To Be Paid By The Auction Winner

Once the bidder wins the auction, it depends on admin how he/she wants the bidder to pay the winning amount.

The winner will either pay the auction winning amount or some percentage of the winning amount set by the admin.

If the admin selects the % of winning bid, he/she needs to enter the percentage amount. Admin can also enter the Capped amount if he/she wants the auction winner to pay the maximum amount.

“Capped Amount is the maximum amount to be paid by the auction winner”.

NOTE:-
In the case of % of winning bid:
-If Entered Percentage of (Auction winning amount)>Capped Amount
Then, the Auction winner will pay the Capped Amount.

-If Entered Percentage of (Auction winning amount)<Capped Amount
Then, the Auction winner will pay the entered Percentage of the winning amount.

Hide Buy Now Button for Purchasing Auction Products

In case you want to charge the winning amount outside the app, you can hide the “Buy Now” button for purchasing auction products of the winners.

Then, you can manually update the purchase status in the app.

To hide the option, You need to visit the Auction Configuration and enable the tab as shown in the below screenshot.

This way, no Buy Now button appears for the winners but, the purchase status can be update in the app once the payment is confirmed outside the app.

Mandate Customer Address and Phone Number

When the ‘Mandate Customer Address and Phone Number’ configuration is enabled.

Customers visiting the website who haven’t yet provided their address and phone number in their profile will be prompted to complete this information.

A pop-up form will appear when they try to place a bid. The form will require them to enter their name, address, and contact number, and then click “Submit” to save the information.

Once submitted, the provided details will be automatically updated in their account section.

If you enable another configuration under ‘Mandate Customer Address and Phone Number’, a validation check will be enforced on the website.

Any customer who tries to place a bid without having their address or phone number saved in their profile will encounter a validation prompt.

They will see a pop-up message:

“Phone number or address details are missing. Kindly fill in these details to place your bid.”

Upon clicking the “Click to enter these details” button in the pop-up, the customer will be redirected to their account page, where they can update and complete the required information.

Real-time Bid Update

The product auction app is now upgraded with the feature of real-time bid update.

So, from now onwards, once a bidder places a bid for a product, the bids will get updated on the auction window page for all the other bidders who are live on auction.

No need to refresh the page again & again to update the last bid placed for any item.

Proxy Bidding

The Admin can enable the functionality of proxy bidding using the Product Auction app on his Shopify store.

So to configure this, visit the Product Auction app from Shopify backend > Configuration > Auction Configuration.

You can notify customers once a proxy bid is placed. For this, you need to enable the settings from the Auction Configuration menu of the app.

Once enabled, you will get an option to configure the mail template on your own.

Allow Customers To Place Normal & Proxy Bid With A Single Button

You can now allow customers to place a normal and a proxy bid using a single button for an auction product.

If the bid amount is greater than Bid Price + 2*(Increment) then, it will be considered as a proxy bid.

Let’s take an example:-
If the current bid amount is 100 and the minimum increment allowed is 10, then if the customer places the bid for 120 [Bid Price + 2*Increment]

or more then it will be considered as a proxy bid for the auction, but in case the customer bids less than 120 then it will be added as a normal bid.

You just need to enable the option from the “Auction Configuration” menu of the app.

Enabling this option will let you choose whether you want to enable Proxy bidding for all the running & upcoming auctions OR only for newly created auctions products.

StoreFront View

Customers will place both normal & proxy bids with the same button.

NOTE:- If the bidding value is greater than and equal to Current Bid + 2*(minimum allowed bid- Current Bid) then, this will be placed as a proxy bid.

Default Bid Rule

Now, the admin can set the default bid rules for the auctioned products of his store.

From this, you can maintain the gap between the bidding amount.
If no specific rule is defined for a particular bid, the nearest applicable increment rule will be applied.

For this, visit Product Auction App > Configuration > Auction Configuration

Click on save the added bid rules, a dialog box will appear. Here, you can decide whether you want these bid rules to be effective on all the auctions or just on future auctions.

The added bid rules will be by default added to all your future auction. Moreover, you can alter the by-default bid rule for any individual auction while adding/editing it.

Here, we have provided the Ban bidder options for the admin –

Ban Bidder

The admin has the option to ban the bidders which he seem unfit to place bids on the auctions set up by them.

Current Bid as a meta field

Once you enable this configuration, the Admin’s store will create the current bid for the auctioned product as a metafield.

The Admin can view the meta field on their Shopify store

Once an auction ends the last current bid’s value for the auctioned product will be stored in the metafield.

When the system creates a new auction on a product, it updates the metafield value to the current bid of the new auction.

Purpose – This meta field can be used by the Admin to create a filter on the collection page.

Note – The functionality will exclusively cater to clients who are subscribed to the Shopify Plus plan and have opted for the pro plan of the Product Auction application

Bidder End

Any buyer can bid on a product when the store owner enables the auction, requiring only a buyer account to participate.

The bidder will see this auction window(ref below image) for the product on which the auction is enabled. The bidder will have to log in and start bidding.

A brief history of bids made can be viewed by the bidder by click on a number of bids section just above place my bid.

History of all the bids made by bidders can be viewed by visiting my account section of the eCommerce store.

Clicking on View your bids button on my account page of the customer will make him view the history of bids made along with current bids,

lost bids and won bids in separate dedicated sections.

Important Note

For the products on which store owner wants to enable auction,

the store owner will have to visit that product from Shopify backend’s product section and have to enable auction by clicking on the three dots on the top right.

Once the auction is selected, that product will start getting reflected in the product section of the Product Auction and the auction can be configured from there.

Refer to the image below:

Winning Flow

Winning flow is simple for a product auction product. As soon as the Auction is finished, the Winner is declared automatically based on the admin configuration.

Winner gets the automatic email from admin that “You have Won an Auction. Proceed further and buy this product”. Admin can modify winner email content from configuration.

As soon as the winner clicks on the ‘Buy Now’ button, they are redirected to their customer account page. From there, they can view the details of the auction they’ve won.

The ‘Buy Now’ button is displayed in front of the corresponding auction product, making it easy for the winner to proceed with the purchase.

Once the winner clicks the Buy Now button, the system redirects them to the cart page, where they can proceed with checkout.

Note: Winner Product at Shopify Back-end

When Admin creates the Auction Product, our app creates a product having the name Shopify Auction during initial configuration.

As an admin, you should never delete or move this product to the Draft state, as doing so will cause the Product Auction feature to stop working.

Additionally, this product must remain available on the Online Store sales channel at all times.

Moreover, if the product is not Active or is Disabled, auction winners will encounter an “Out of Stock” error on the checkout page.

The system creates the auction product as a variation but applies the auction widget to the actual product that customers see on the front end.

As a result customer placed the bid on the actual product and received an email if declared as the winner to buy a variation product.

Place bid on behalf of customers

Now, the admin can place bids on behalf of customers using a CSV file.
for this, go to the AUCTIONS section >> click on “Place bid”

Now, you will have the option to upload a CSV file to bid place on behalf of the customer and you will find an option to download a sample CSV file

but go through instructions for the CSV file then upload the CSV file to place a bid.

Restrict Consecutive Bidding

Now merchant can restrict consecutive normal and proxy bidding.

In order to enable this feature you need to navigate in product auction app configuration >> auction confiq >> restrict consecutive bidding

Reconcile Order

When an auction ends, the highest bidder is declared the winner. If the winning bidder successfully completes the purchase, the Product Auction app will update the status to ‘Purchased’ accordingly.

However, in some cases, even though the product status appears as ‘Purchased’ in the app, the ‘View’ button—which links to the order page—may not be visible in the Winner Details section.

If the ‘View’ button is missing, it indicates that the winner has purchased the product, but the order was not successfully synced with the user’s account or the store.

This may have occurred either because the customer used a different email during checkout, or possibly due to a sync failure resulting from some other issue..

As a result, the ‘Purchased’ status will not appear on the winner’s account, and the ‘Buy Now’ option will still be visible.

To resolve this issue, we have provided a feature called ‘Reconcile Order’ in the Product Auction app, which helps manually sync the order.

You can access this feature by navigating to:
Product Auction App > Auctions > Reconcile Action > Reconcile Orders

How it works:

When you click on ‘Reconcile Order’, a pop-up will appear where you can select the desired date range.

After clicking ‘Proceed’, the system will attempt to reconcile the order—provided that the product was indeed purchased by the winning bidder.

Once reconciliation is successful:
The product status will be marked as ‘Purchased’.

A ‘View’ button will appear in the Winner Details section. Clicking on this button will redirect you to the corresponding order for the product.

The order will also be reflected as ‘Purchased’ on the customer’s account page.
In addition, you will receive a confirmation email with a CSV file attached.

This file will contain the details of all reconciled orders, including the auction ID, the email of the customer assigned to the order, and the email used during checkout:

Auction ID

Customer Email (Assigned To)

Customer Email (Order With)

This process ensures proper alignment of all auction order records and effectively resolves any discrepancies between auction wins and order creation.

Manage Orders

If you want to manage orders either within the store or outside the store, we provide a ‘Manage Orders’ configuration in the Product Auction app, through which you can select your preferred option.

When you set ‘Manage Orders’ to Within the store, the winning product can be purchased directly through the store using the standard ‘Buy Now’ option.

In this case, Shopify will handle the order processing as usual.

However, when you set ‘Manage Orders’ to Outside of the store, the winner will purchase the product directly from the seller or admin outside of the app.

Please note that this feature is primarily designed for the Multivendor Marketplace.

In this kind of setup, individual sellers typically prefer to auction their own products and, furthermore, manage their sales independently.

In the ‘Outside of the store’ setup, instead of the ‘Buy Now’ button, the winner (customer) will see a ‘View Details’ button.

When clicked, it will immediately display the vendor’s details—such as name, email, phone number, and address—for quick reference.

We’ve introduced a new feature for upcoming auction products.

With this update, you can now display upcoming auction products on the checkout page. To learn more, check out our detailed blog here.
