If your segment is not listed
It is worth asking anyway. An auction is a surprisingly stable object underneath: lots with descriptions and images, bidders with accounts and credit, a bid sequence with rules, a close, an invoice, a settlement. What differs between segments is which fields matter, how lots are grouped, what the fee structure looks like and which documents have to travel with a lot.
All of those are configuration on this platform. That is why an audiovisual auction house and a bankruptcy administrator can run on the same codebase without either feeling like an afterthought.
The most unusual one we have done
Broadcasting airtime. The lots were advertising slots in a television schedule — no photographs, no physical pickup, no condition report, and a hard deadline set by the broadcast itself. It needed a different lot template and different close behaviour, and nothing else about the platform had to change.
Where it does start to strain
Being straight about the edges: if your sale is not really an auction — a fixed-price marketplace, a tender with negotiated terms, a subscription — then this is the wrong tool and we will tell you that in the first conversation rather than the fourth.
In practice
Best Wine Auctions is a good example of a segment that did not exist in our plans until a customer brought it. They present some of the world's most prestigious wines and champagnes, with every bottle meeting exacting standards before it is listed, and asked for software that felt as exclusive as the contents. We built a bespoke front end with their marketing team, plus native iOS and Android apps, on the standard platform underneath.
