Sample Letter of Request for Additional Units for Expanding Seasonal Inventory

Dear Mr. Thompson,

I hope you are doing well. Thanks for your continued partnership with BrightSun Retail. During the upcoming holiday season, demand for our Eco‑Friendly Face Wash is projected to exceed our current stock by approximately 4,000 units. Our sales data from the same period last year showed a 35% increase in demand across the Southwest region.

To avoid stockouts and capitalize on the sales opportunity, I request an additional 6,000 units of the Eco‑Friendly Face Wash, with delivery scheduled by October 15th. This additional inventory will ensure we meet consumer demand and retain at least 90% of the projected sales volume.

We appreciate your prompt attention to this request. If you need further data or a detailed forecast, please let me know. I’ll be happy to provide it.

Thank you for your support.

Sincerely,
Lisa Martinez

Sample Letter of Request for Additional Units for Equipment Replacement in a Manufacturing Plant

Dear Ms. Chang,

My name is Rahul Patel, and I oversee operations at Acme Manufacturing. During a recent audit, we identified that 12 out of 45 of our CNC milling machines are experiencing a 15% decrease in production efficiency due to wear and tear. Meeting our production targets for Q3 requires an additional 4 CNC units.

Here are the details of the request:

Quantity: 4 units
Justification: The loss of 12 machines reduced our throughput by 32%, directly threatening our 12,000 unit delivery goal.
Delivery deadline: May 20th, 2026

Purchasing these units will bring us back to optimal capacity and prevent further delays. We anticipate full utilization within the first week after installation.

Please let me know if you need a detailed cost breakdown or risk assessment. Thank you for promptly considering this critical investment in our production line.

Best Regards,
Rahul Patel
