Is free silent auction software really free?

Some platforms have no upfront software price but charge a percentage of funds raised, add optional donor tips, or reserve features for paid plans. Compare what your organization pays across the whole event, including platform fees, payment processing, branding, and support. The cost calculator models fixed software costs and percentage fees without treating payment processing as a PHP Pro Bid charge.

Running the same auction every year

Run each annual, seasonal, or always-on fundraiser on the same branded installation. Your bidder accounts and auction records stay in one place, and PHP Pro Bid does not add a new software fee each time you create an event.

Three plans

Choose for your team and expected traffic

Every plan supports silent auctions and nonprofit fundraising. Many lots increase the catalog work. Many guests bidding near the same closing time create the traffic peak.

Best for larger events

Managed VPS

£159 /month
Billed annually

We manage private server resources for you. This is the preferred hosted plan for larger catalogs or heavier simultaneous bidder traffic. Source code,* backups, Unbranding, and priority support are included.

Choose Managed VPS
Self-hosted

License

£399 one-time
No annual software fee

Install it on compatible hosting you control. Event capacity depends on that server. Support is included, and optional hosting and same-day installation are available.

Choose the License

Planning a large event? Tell us how many lots you expect, how many guests may be online together, and whether several lots will close within a short period. We can recommend Cloud or Managed VPS before you order.

*License and Managed VPS include the PHP source code. A small number of licensing and security files are encoded with ionCube.

Check the fit

What PHP Pro Bid does, and what it does not replace

This is auction software. It is not presented as a complete nonprofit-management suite.

PHP Pro Bid handles

  • Online and silent-auction catalogs
  • Bidder registration and bidding
  • Timed closing and bid extensions
  • Winner invoices and online payments
  • Your domain, logo, colors, and theme

Ask us to scope as custom work

  • Donor CRM or campaign-management integrations
  • Event ticketing, seating, or check-in tools
  • Tax-receipt workflows for your country
  • A particular bidder-data export
  • Other charity-specific workflows

These are not included as standard features. Our Custom Development service can scope new features or integrations. A branded iOS and Android app is available through our mobile app service.

Not sure whether it fits? Send us your event format, expected bidder count, payment gateway, required exports, and any missing workflow. We will separate what the standard platform already covers from any custom work before you order. Ask about your setup.

Common questions

Silent auction software FAQ

Do bidders need to download an app?

No. The auction works in a mobile browser. Guests visit your auction URL, register on your site, and bid without installing an app. A branded native app is available only as a separate custom development service.

How does payment collection work?

You connect your own PayPal or Stripe account. When a winner pays through your enabled gateway, the payment goes to your account. PHP Pro Bid takes no percentage, although your payment provider may charge its normal processing fee.

Can I use my charity's own branding and domain?

Yes. Every plan can use your domain, logo, colors, and theme. Unbranding removes visible PHP Pro Bid attribution. It is an optional paid add-on for Cloud and License, and it is included with Managed VPS.

Can I run a silent auction during a gala?

Yes. You can run a timed silent auction alongside your gala and manage it from the same admin panel. Guests bid from their phones, and you can stagger lot closing times through the evening.

How many auctions and lots can we run?

PHP Pro Bid does not impose a software limit on the number of auctions or lots. Practical capacity depends on the hosting, image sizes, and how many people browse and bid at the same time. Cloud removes the server-management work. Managed VPS provides private server resources and is the preferred hosted option for a larger catalog, heavier bidder traffic, or repeated events. License capacity depends on the hosting you provide.

Can we use PHP Pro Bid if we are not a registered charity?

Yes. Schools, PTAs, churches, sports clubs, community groups, foundations, and other organizations can use the platform for fundraising auctions.

What should we compare with a per-event fundraising platform?

Compare the full cost: per-event charges, platform percentages, payment-processing fees, hosting, setup, and optional branding. Also check browser bidding, invoicing, support, and data requirements. PHP Pro Bid charges no per-event fee and takes 0% of winning bids. Use the cost calculator to compare the three PHP Pro Bid plans.

What happens if a winning bidder does not pay?

You control the payment process. Winners receive invoices and payment instructions, and you can manage unpaid invoices from the admin area.

Is this suitable for a school PTA with a limited budget?

It can be. Cloud is the simplest starting option when nobody wants to manage a server. The £399 one-time License can suit a PTA with compatible hosting and technical help. Neither option adds a fee for each auction.

Is PHP Pro Bid free for nonprofits?

No. PHP Pro Bid is paid software. Choose a one-time £399 self-hosted License, Cloud from £63/month, or Managed VPS from £159/month when billed annually. There is no per-event PHP Pro Bid fee and no PHP Pro Bid percentage on winning bids.

Can we run repeat or year-round charity auctions?

Yes. PHP Pro Bid does not impose a software limit on the number of auctions you run. You can create each fundraiser on the same branded installation, keep bidder accounts and auction records in one place, and pay no additional PHP Pro Bid fee for each event. Hosting and payment-processing costs remain separate.

Who controls our bidder data?

Your bidder accounts and auction records are your organization's data. With the self-hosted License, the database sits on your server. If you need a specific export format or retention process, ask us to confirm it before ordering.
