The hammer is the halfway point
Legacy auction systems stop when the lot is sold. The real work starts there: invoicing, collecting, shipping, VAT, the ledger. This platform finishes the job.
Getting paid
From hammer to money in the bank
Your own Stripe account
Card, SEPA and MobilePay settle directly to the house. You are the seller of record, and the platform takes 0% of it.
Invoices your accountant approves of
Sequential numbering with your prefix, your logo, localized in five invoice languages, margin-scheme aware.
Links, reminders, bank transfer
Stripe payment links per order, polite reminders with fresh PDFs, and manual mark-paid for bank transfer and cash. Your bank details and payment terms print on the invoice itself.
Buyer–consignor set-off
When the same person is owed proceeds and owes on an order, settle the net. Both legs are still booked gross and reversible.
Shipping that charges correctly
Per-country shipping zones with named delivery options and parcelshops; labels booked automatically on payment; fees frozen on the order so edits never change what a paid buyer owes. International shipping quoted after the sale goes out as its own invoice, with its own PDF and card link.
Award it to the runner-up
Reassign a won lot when a buyer walks away, or pull a damaged lot off an invoice and send it back to the next sale. Both orders recompute in one transaction.
Refunds without spreadsheets
Partial and full refunds reconciled against the order, with the paper trail intact.
Closing the books
Month-end is a date range and a download
Built for how an auction agent legally works, wherever you operate: hammer as consignor liability, commission as revenue, VAT on the margin.
Agent-grade accounting
Netto consignor accounting by default: the hammer passes through, commission is recognised, and the ledger matches how your accountant expects an auction house to book.
Margin-scheme VAT, per order
Built for the second-hand margin scheme, per order, with export treatment when a lot leaves the tax area and company-buyer invoicing that carries registration and VAT numbers. Reviewed with our customers' own accountants.
Syncs to your accounting system
Orders, payments, refunds and payouts post continuously to your ledger, invoice PDF attached to each voucher. No re-keying, no month-end export ritual. Dinero (Visma) runs in production today, and each connector is a self-contained adapter. Yours is a short conversation, not a roadmap item.
Files in the format your accountant expects
Standards-compliant voucher exports for any date range, deterministic and logged, so a filing can always be reproduced. SIE 4 for the Nordics today, plus universal CSV that imports anywhere; further national formats on request.
Your chart of accounts
Sensible defaults per country out of the box, and every account remappable to the chart your bookkeeper already runs.
CSV for everything else
Results by buyer and consignor, exports per auction. Nothing is locked in.
