Asked by a buyer from Hyderabad.
Because in this industry it is true, and I would rather write it down than surprise you. A quote is a snapshot of pricing on the day it was issued; the advance is what converts it into a promise.
The mechanics. AV brands in India revise MRPs and dealer pricing periodically, often at financial-year boundaries, sometimes mid-year when the rupee moves against the dollar or euro, since most of this equipment is imported. A quote is priced on the MRPs current at issue. So our quotes carry the terms any straight dealer's do: pricing valid against current MRPs; brand revisions apply to unconfirmed orders; confirming with an advance blocks your pricing.
Does that mean the price will change on you? Only if you wait and the brand revises. Within the validity window nothing moves. After it, we refresh the quote and it may go up, may go down, and usually goes up by a small amount at year boundaries.
Guidance. Settled on a system and a revision has been announced? Confirming beats waiting; the advance is cheaper than the increase. Months from being ready, with civil work still to finish? Expect a refreshed quote rather than a stale one honoured, and use the time to get the wiring plan right, which matters more than a few percent on the electronics.
Be suspicious of any seller who will "hold" a price indefinitely with nothing confirmed. Someone absorbing that risk for free is recovering it somewhere else, usually in what they substitute or in what they leave off the quote.
The same logic applies at every authorised dealer, and it applies to us. If you want to know whether a specific line on your quote is at risk of revision soon, ask; we usually know which brands are due.
