Buyer's Premium

Add a percentage on top of the winning bid, charged once when the auction settles — a common auction-house practice. Set the percentage on the auction's admin form. Auctions with no premium set settle at the plain winning bid.

Changelog

  1. Version 1.0.12 4 Nov 2026

    - For developers: this plugin now tells the coming Clear test data tool what to do with each of its tables (empty it, keep it, or remove it only with customer accounts). Nothing changes for store owners yet.

  2. Version 1.0.11 29 Oct 2026

    - Amharic (አማርኛ) translation, machine-translated (review welcome).
    - Oromo (Afaan Oromoo) translation, machine-translated (review welcome).

  3. Version 1.0.10 26 Oct 2026

    - Adds Thai (ไทย). Machine-translated; review welcome.
    - Japanese translation.
    - On wide screens the buyer's premium sits beside the other short settings on the auction form.

  4. Version 1.0.9 25 Oct 2026

    - Adds Polish (pl) text. Machine-translated.

  5. Version 1.0.8 21 Oct 2026

    - Raising the buyer's premium on a lot that already has bids, or changing it on a lot that has been won, bought or cancelled, is now refused with a message instead of saying 'Auction saved.' and keeping the old premium. The form says why the field is limited.
    - A malformed buyer's premium value in an admin save no longer sets the premium to 1%.
    - The Troubleshooting help now explains how to check a disputed amount: the winnings and order show one total, and the premium is the difference from the winning bid.

  6. Version 1.0.7 18 Oct 2026

    - Once a lot has bids its buyer's premium can only be lowered, and once the lot is won, bought or cancelled it can't be changed.
    - A very large winning bid with a premium no longer stops the lot from settling.

  7. Version 1.0.6 18 Oct 2026

    - The Buyer's Premium heading and its note on the admin auction form are shown in the admin's language.

  8. Version 1.0.5 16 Oct 2026
