Auction House Management Software: Custom Build vs Package (London Benchmark, 2026)

The verdict in three sentences

For an auction house holding 40 sales and 15,000 lots a year, the real cost is not the licence but the re-keying between catalogue, absentee bids, live platforms and invoices. A specialist package still makes sense below 8,000 lots a year and with a single online channel. Above that, a custom build at GBP 43,000 to 103,000 (EUR 50,000 to 120,000), connected to live bidding platforms such as the-saleroom or Drouot Digital and equipped for AML compliance, frees the equivalent of one to two admin roles.

Where an auction house loses its hours

A lot's cycle is long: consignment, inventory, photography, cataloguing by the specialist, estimate, publication, absentee and phone bids, room and live sale, hammer, buyer invoice, payment, collection, vendor settlement. Every step poorly linked to the next creates re-keying.

On 15,000 lots, saving 8 minutes per lot in cataloguing already means 2,000 hours a year, more than one full-time role.

Package or custom build: the numbers

One point often overlooked: live platforms charge their own fees (often an extra 3 to 5% of hammer to the buyer). A site with integrated online bidding captures part of those sales without an intermediary.

Compliance: what the software must track

In the UK, art market participants handling transactions of EUR 10,000 or more fall under the money laundering regulations, as do French auction houses under LCB-FT rules. You must identify buyer and seller, keep records for five years and be able to report a suspicious transaction. Good software generates these registers from inventory, blocks the release of a lot if documents are missing and logs every change. It also handles artist's resale right for eligible works and export licences for cultural goods.

Mini case study

James, a partner at an auction house in Kensington, runs 40 sales a year for 15,000 lots and GBP 7.7 million in hammer total. His admin team has 4 people, with about 1.5 roles absorbed by re-keying, roughly GBP 60,000 a year fully loaded.

He chooses custom software at GBP 81,000 with GBP 850 a month of maintenance. Re-keying drops by 70%, saving GBP 42,000 a year. His integrated live bidding captures 10% of online bids that previously went through a third-party platform, worth about GBP 15,000 of extra buyer's premium retained. Net annual gain: about GBP 47,000, payback in 21 months.
