Definition and computation rule

In the product form, you can configure some information for customer lead time, manufacturing lead time, and delivery lead time. Moreover, the security lead time is also configured as a backup method to cope with the possible unexpected delays. Before taking a deep insight into the configuration and practical applications of each, here is a brief definition of each term:

  1. Vendor’s Delivery Lead Time: the time for the vendor to deliver the goods. Expected Receipt Date on Purchase Order = Order date + Vendor’s Delivery Lead Time.

  2. Purchase Security Lead Time: additional time to mitigate the risk of a vendor delay. When you work with a new vendor or the vendor who has inconsistent delivery lead time, it is essential to configure this feature. The expected delivery Deadline = Expected Receipt Date on Purchase Order + Purchase Security Lead Time.

  3. Customer Lead Time: the number of days promised to customers (in days) from the time the sale order is confirmed until the product is ready to be shipped to the customer. The expected Delivery Date on Sales Order = Order date + Customer Lead Time.

  4. Sales Security Lead Time: the pre-configured safety time to reduce the risks of delivery delays in sales. The Scheduled Date on the delivery order = The expected Delivery Date on Sales Order - Sales Security Lead Time.

  5. Manufacturing Lead Time: the expected time it takes to manufacture a product. This lead time is set for each product and does not take the quantity into account.

  6. Manufacturing Security Lead Time: the additional time to mitigate the risk of a manufacturing delay, which is useful in cases of bulk production orders. This is set for all the manufacturing orders. The Planned Date = the Delivery Order scheduled date - Manufacturing Lead Time - Manufacturing Security Lead Time.

  • A delivery Lead time of vendor X with the product as A: 4 days.

  • Purchase Security Lead Time: 1 day.

  • Order Date: February 09th, 2022.

Make a purchase order from Vendor X with product A. scheduled receipt date will be automatically computed (February 13th, 2022) = Order date (February 9th, 2022) + Vendor Delivery Lead time (4 days).

Make a purchase from a vendor

Once the purchase order is confirmed, a receipt slip is automatically generated. Deadline displayed on the slip (February 14th, 2022) = The Scheduled Date (February 13th, 2022) + Purchase Security Lead Time (01 day).

For example, Customer Z wants to order product A with the following information:

  • Customer Lead Time: 10 days.

  • Security Lead Time for Sales: 01 day.

  • Order Date: February 09th, 2022.

In the Sales app, create a sales order for Product A for Customer Z. In the Order Lines tab, the lead time is displayed as 10 days as configured customer lead time in Product A. In the Other Info tab, the Expected Delivery Date is automatically calculated based on the delivery time set on the product( February 19th, 2022) = Order Date (February 09th, 2022) + Customer Lead Time (10 days). There is also a Delivery Date that allows you to choose the delivery time at your will.

Customer Lead Time in Sales Confirm the Sales order

Note

In case there is no change in delivery date, the scheduled date is default as the expected delivery time.

Once the sales order is confirmed, a delivery slip is automatically generated. In this slip, the deadline (February 19th, 2022) = The Scheduled Date. Scheduled delivery date on the delivery slip (February 18th, 2022) = Expected delivery date (February 19th, 2022) - Customer Lead Time (1 day).

If the delivery date is earlier than the expected date, a warning message is displayed.

However, to make sure all of these work properly, security lead time for sales should be calculated and configured precisely.

Deliver several products

In reality, there are cases where a customer orders many products at once but wants to have them delivered at the same time or separately. For example, on February 12th, 2022, there is an order for products A and B. The delivery time for product A is 10 days, and for product B is 5 days.

Make a sales order

Viindoo provides you with two options for the shipping policy, which can be configured from the Other Info tab of your Sales order.

  • When all products are ready: deliver all products at the same time. A delivery slip is scheduled based on the product with the most lead days. In the above example, the expected delivery date will be calculated according to the delivery time of product A which is February 22nd, 2022.

Shipping Policy as When all products are ready Validate the delivery slip
  • As soon as possible: separate delivery. The system relies on the product with the least customer lead days to calculate the delivery date. For example, B is the product with the least lead days. So, the expected date is on February 17th, 2022.
