One update, every bill
The mills send a rate on WhatsApp in the morning, you work out your selling rate, and you update the item. From that moment every bill anyone raises uses it — the counter, the supervisor at a site, the second branch. What this prevents is the most expensive small mistake in the trade: a staff member billing at yesterday's rate because that is the number they remember. On a few tons of steel that is a real amount, repeated quietly.
Party-wise rates
Wholesale and distribution do not have one price. A regular dealer has his rate, a new buyer has another, and a party who settles in a week has earned a third. Rates held against the party mean the right price appears when the party is picked, rather than depending on who is behind the counter. Where something is negotiated on the day, the line can be overridden without changing the party's standing rate — the override is recorded, so you can see later what was given away.
Sharing a price list
Contractors and dealers ask for a rate list constantly, and most shops send a photograph of a handwritten sheet. A proper price list generated from your items, with your shop details on it, goes out as a PDF on WhatsApp and reflects today's rates rather than whatever was written last month. For a wholesaler that is worth a surprising amount in enquiries that convert without a phone call.
Watching the margin close
Rates rise on the purchase side faster than selling prices get revised, because revising a selling price is a conversation and updating a purchase cost is not. Purchase rate against sale rate per item shows exactly where that gap has closed. Running it monthly is a five-minute habit that regularly finds a line that has quietly stopped making money.
Quoting a rate that holds until tomorrow
The daily rate creates an awkwardness at the counter that every steel dealer knows: a contractor asks for a price in the morning, comes back at four, and the mill has moved in between. The workable answer is to be explicit rather than to absorb it — a quotation carries a validity period, so the rate quoted is the rate honoured until the date on it and no longer. Putting that in writing removes the argument entirely and it reads as professional rather than difficult. For regular parties, holding a standing rate against them does the same job without a quotation each time.
