Yes. Each auction carries its own minimum increment, and you can set it when you create the listing.
The default, if you set nothing
5% of the starting price, with a floor of ₹10.
Of the starting price, not the current one — so the step is fixed for the whole auction and does not grow as the bidding rises. An item opening at ₹500 steps in ₹25 whether the price reaches ₹600 or ₹6,000. Why is the price jumping in big steps?
That default is sensible for most things, which is why most sellers never touch it.
When to change it
Larger, for a high-value item opened low. A ₹40,000 piece opened at ₹1,000 steps in ₹50 by default, which is two hundred bids to get there. Setting a bigger step keeps the auction moving.
Smaller, for something inexpensive where you want lots of small bids. A ₹200 item with a ₹10 step gives more bidding moments than one with a ₹25 step, and bidding moments are what a live room runs on.
The thing to get right instead
The starting price, by a wide margin.
The increment is derived from it, so the start price sets both at once. And the start price is the thing that decides whether anybody bids at all — the commonest reason an auction gets no bids is an opening that asks the room to take the first risk.
So: choose the start price for the bidding you want, and let the increment follow. If the resulting step feels wrong, then adjust it. How to price for auction
What is not configurable
The ten-second rule. On a standard auction, a bid in the final ten seconds pushes the clock back to ten seconds. You cannot change it, and you should not want to — it is what stops sniping and makes the ending a function of bidding rather than of reflexes. The last ten seconds
Maximum bids. Buyers can set a ceiling and have Metzee bid for them, and nothing a seller sets switches that off. It is also invisible to you, which is why an item sometimes bids back instantly. What a maximum bid is
The formats. Three exist: standard with the ten-second rule, reset-timer, and sudden death where the clock never moves.
Once it is running
Settings lock at the first bid, and at the moment the auction goes live. So the increment is a decision made before the item goes up. How to edit or relist an item
What buyers see
The next valid amount, always. The Bid button is that amount, which is why a buyer using the button can never be rejected — and why a bid below the step is not a low bid, it is not a bid. Is there a minimum bid?
