Migrate from HiBid/Proxibid to Custom Auction Platform

You built the auction business. You source the lots, cultivate the bidders, run the events. But HiBid takes a cut of every transaction. Proxibid owns your bidder relationships. LiveAuctioneers controls your SEO. AuctionWorx locks your lot history behind their export limits.

Every month you pay platform fees, per-event charges, and 2.5–3.5% transaction fees on revenue you generated. Over time, that adds up to a second business—one that belongs to someone else.

We build custom auction platforms on Next.js and Supabase that you own completely. Your bidder database. Your lot history. Your domain authority. Your margins.

The Real Cost of Auction SaaS Lock-In

Auction SaaS platforms sell convenience. What they don't advertise is the compounding cost of dependency:

Per-Event and Transaction Fees Eat Your Margins

HiBid and Proxibid charge per-event fees ($100–$500 per auction) plus percentage-based transaction fees. If you're processing $500K+ annually, you're sending $15K–$25K/year to your platform provider before hosting, add-ons, or webcast upgrades. That's a custom platform amortized in 2–3 years.

Your Bidder Database Isn't Yours

On HiBid and LiveAuctioneers, bidders register with the marketplace—not with you. If you leave, you lose direct access to those relationships. Your carefully built audience becomes someone else's retention metric. Try exporting your full bidder history with contact details, bid patterns, and lifetime value. Most platforms make this deliberately painful.

Lot History and SEO Equity Are Trapped

Years of past auction results, lot descriptions, and realized prices live on HiBid's domain, not yours. Every backlink pointing to your HiBid-hosted catalog belongs to them. When you migrate without a redirect strategy, you start from zero.

Feature Requests Go Nowhere

Want custom bid increments for specific lot categories? A different commission structure for consignors? Integration with your existing CRM? On SaaS platforms, you submit a feature request and wait. On your own platform, you ship it next sprint.

What a Custom Next.js + Supabase Auction Platform Gives You

This isn't about reinventing auction software. It's about rebuilding the parts that matter on a stack you control.

Real-Time Bidding That Actually Scales

Supabase Realtime runs on PostgreSQL's built-in replication. Every bid, every proxy bid update, every countdown timer syncs across all connected clients via WebSocket subscriptions. No polling. No third-party WebSocket service. Sub-100ms latency for live bidding events with hundreds of concurrent bidders.

Server-Rendered Auction Catalogs for SEO

Next.js server-side rendering means every lot page, every past auction result, and every category landing page is fully indexable. Googlebot doesn't need client-side JavaScript to see your content. Your auction results become long-tail SEO assets that compound over years.

Full Ownership of Bidder Data

Supabase Auth handles registration, email verification, and session management. Your bidder table lives in your PostgreSQL database. You control the schema, the export format, and the retention policy. Connect directly to HubSpot, Mailchimp, or your own email pipeline.

Proxy Bidding, Timed Auctions, and Live Webcast

We implement proxy bidding logic at the database level using PostgreSQL functions and triggers—not application code that can be bypassed. Timed auctions with anti-sniping extensions, buy-now options, and reserve prices are all first-class features. Live webcast integration connects via your preferred streaming provider.

Consignor Portals and Commission Management

Give consignors self-service access to track their lots, view realized prices, and download settlement reports. Custom commission structures—flat fee, percentage, sliding scale, buyer's premium splits—are built into the data model, not bolted on.

Our Migration Process

Migrating from an auction SaaS platform to a custom build requires precision. Bidder trust, lot history integrity, and search rankings are all at stake.

Phase 1: Data Extraction and Audit (Weeks 1–2)

We extract everything the platform will give us: lot history (descriptions, images, bid history, realized prices), bidder profiles, consignor records, and transaction logs. Most platforms support CSV or XML exports. For platforms with limited export tools, we use API access or authorized scraping to capture complete records.

We audit the data for integrity—duplicate bidder accounts, orphaned lot records, missing images—and build a clean canonical dataset.

Phase 2: Platform Build (Weeks 3–8)

We build your auction platform on Next.js with Supabase as the backend. The core deliverables:

• Auction catalog with lot detail pages, image galleries, and condition reports
• Bidding engine with proxy bidding, timed auctions, and real-time updates
• Bidder registration and authentication with email/SMS verification
• Admin dashboard for lot management, auction scheduling, and reporting
• Consignor portal for self-service lot submission and settlement tracking
• Payment integration via Stripe for buyer's premium and invoice processing
• Search and filtering with full-text search across lot descriptions and past results

The frontend deploys on Vercel's edge network. Supabase runs on managed infrastructure with automatic backups and point-in-time recovery.

Phase 3: Data Import and URL Mapping (Weeks 7–9)

We import the cleaned dataset into your Supabase PostgreSQL database. Every lot, every bidder, every past result gets a new canonical URL on your domain.

Then we build the redirect map. Every indexed URL from your old HiBid, Proxibid, or LiveAuctioneers presence gets a corresponding 301 redirect to the equivalent page on your new site. This preserves your search rankings and ensures bidders who bookmarked old lot pages land in the right place.

Phase 4: Testing and Parallel Run (Weeks 9–10)

We run the new platform alongside your existing SaaS setup. Test auctions with internal bidders validate the bidding engine, payment flow, and notification system. Load testing simulates concurrent bidding at 2–3x your peak historical traffic.

Phase 5: Cutover and DNS Migration (Week 11)

DNS switches to the new platform. 301 redirects go live. We monitor Search Console for crawl errors, indexing issues, and ranking changes for 30 days post-launch. Your old SaaS account stays active in read-only mode as a fallback.

SEO Preservation Strategy

Auction platforms accumulate significant organic value through past results pages. Our SEO preservation approach:

• Complete URL mapping: Every indexed page on the old platform maps to a new URL via 301 redirect
• Structured data: Lot pages include Product and AuctionEvent schema markup for rich snippets
• Past results as content: Historical auction results become permanent, indexable pages—not gated archives
• XML sitemaps: Auto-generated sitemaps for active lots, past results, and category pages submitted to Google Search Console on day one
• Canonical tags: Prevent duplicate content issues across catalog views, search results, and category filters
• Core Web Vitals: Next.js SSR + Vercel Edge delivers sub-300ms TTFB and 95+ Lighthouse scores out of the box

Timeline and Pricing

A typical auction platform migration runs 10–12 weeks from kickoff to cutover.

Standard migration (timed auctions, proxy bidding, bidder/consignor portals, payment integration, data migration, 301 redirects): $65,000–$120,000 depending on data volume and custom feature requirements.

Enterprise migration (live webcast integration, multi-location support, advanced analytics, custom commission structures, API integrations): $120,000–$200,000.

Ongoing hosting and infrastructure costs run $200–$800/month on Vercel + Supabase Pro, replacing $1,500–$3,000+/month in SaaS fees and transaction charges. Most clients hit positive ROI within 18–24 months.

The Math Is Simple

If you're running 50+ auctions per year and processing $500K+ in annual GMV, you're paying your SaaS platform $20K–$40K annually in fees. A custom platform pays for itself, then keeps paying you back—every year, forever. And you never have to ask permission to build the features your business needs.
