Bidstrap.

Pricing

Pricing rebuilt around the bidder networkyou didn't have to build.

One plan. A take-rate that descends as you grow. The bidder network is in the price — not an upsell.

Run the numbers

What would your house pay?

Drag the slider or type your annual hammer sales (your GMV). The figure to the right is your all-in cost on the Standard plan — base plus take-rate plus any add-ons you switch on. No accounts, no email capture.

The bands

A smaller percentage as you grow.

Take-rate applies per band, not flat. A house doing £1M a year pays 1.0% on the first £500k and 0.75% on the next £500k — never 1.0% across the whole £1M.

  1. 1.0%£0 – £500kper year
  2. 0.75%£500k – £2Mper year
  3. 0.5%£2M – £20Mper year
  4. Bespoke£20M+bespoke

Measured on hammer only — never your buyer's premium. That's your fee, not ours. Rolling 12 months.

Above £20M, or need bespoke?

Enterprise is a conversation.

Multi-region houses, reseller groups, multi-room consolidators, and houses turning over £20M+ in hammer. Bespoke contract with negotiated take-rate cap, dedicated account manager, premium SLA, full white-label depth wherever your payment and login providers allow. Houses that cannot accept any Bidstrap presence at identity moments are looking for bespoke development — that's not us.

In the contract

The clauses that protect you.

Three standard MSA clauses ship with every Bidstrap contract — not just Enterprise. They're the answer to “what stops you raising prices” before you ask.

Pricing locked for the contract term
Take-rate, base, and band thresholds are fixed for your 24-month initial term. On renewal we can raise the take-rate by at most UK inflation year-on-year, and the base by at most inflation plus 5 percentage points — with 60 days written notice. The percentage you sign at is the percentage you pay.
We never charge your buyers
Bidstrap takes its fee from you, not from the bidder. We won't introduce buyer-visible fees without your written consent. You can choose to pass platform fees on through your buyer's premium — your call, not ours.

First 90 days

Onboarding is on us.

Zero base. Zero take-rate. Zero per-lot fee. For your first 90 days, or your first £100k of hammer sales — whichever comes first. Third-party costs (Stripe, identity checks) still flow at-cost. One holiday per house.

Start the 90 days

FAQ · The honest answers

Why a take-rate? Most platforms charge flat.
The take-rate funds the shared bidder pool — warm leads from every other Bidstrap house, flowing into your sales. A flat-fee platform doesn't grow that network for you. It also aligns our incentives: if your hammer doesn't fall, we don't get paid.
What stops you raising the take-rate in year three?
The contract. Take-rate, base, and band thresholds are fixed for 24 months. On renewal we can raise the take-rate by at most UK inflation, with 60 days written notice. (CPI-capped.)
What does the 90-day holiday actually cover?
Your first 90 days, or first £100k of hammer sales — whichever comes first. No base, no take-rate, no per-lot fee. Third-party costs (Stripe, identity checks) still flow at-cost. One holiday per house.
Can I cancel or downgrade?
Month-to-month on the Standard plan. Cancel or remove add-ons from your billing portal — takes effect next cycle. No exit fee.
What about VAT and tax?
UK B2B VAT (20%) on your subscription and take-rate. We capture your VAT number at signup for EU reverse-charge invoices. Buyer-side VAT on hammer and premium runs through your own tax setup — separate, fully under your control.
Do other auction houses get my bidder list?
No. The shared pool shares trust signals — verification status, payment reputation, fraud flags — not contact data. No other house can list, search, or market to your bidders.
What about charity sales? Won't the take-rate eat penny lots alive?
No. Charity sales are self-marked at the clerk console — the per-lot fee drops to £0.025 and the take-rate maths on sub-£1 hammers is negligible anyway. Charity sales are welcome; they're goodwill marketing for your house.
Can I opt out of the marketplace?
Yes, on every plan. Your lots appear in the cross-house marketplace only if you opt in. The premium analytics add-on adds granular controls: anonymise your house name, geo-restrict visibility, suppress specific lots.
What about my AML responsibility if identity checks are shared?
Verification is canonical at Bidstrap; acceptance is your call, per auction. Require Bidstrap-verified identity, add your own checks on top, or refuse imported attestations entirely. Your regulator sees a regulated supply chain, not a delegation.
Can I bring my own accounts, shipping, or insurance providers?
Yes. Modules are sticky defaults, not lock-in. Every action is published as an event you can route into Sage, your existing carrier, your underwriter — anywhere. We document the contracts; you swap in what you need.
