Step-by-step explanation:
As the Sales Manager of Shah Brothers, I would craft a sales letter to Patel and Company informing them of the product offerings and the impending price increase. The letter would clearly outline the availability of four types of lathe machines and ten types of machine spares.
We are pleased to offer a unit price for one of our lathe machines at INR 200,000 and a unit price for each spare part at INR 2,000. The total cost for your selections will be calculated based on your order quantity. Please note that these prices are only valid until December 31, 2023.
After this date, we anticipate a price increase due to changes in market conditions. In addition to the price change, there might also be revisions in our terms and conditions for supplies. We highly recommend placing an order before this date to take advantage of our current pricing.
