Shipping Date & Delivery Date: Definitions, 4 Key Differences & 7 Important Factors Affecting These Dates in 2024

After order confirmation, an eCommerce platform’s customers lookout for one critical piece of information: when will they receive their package? And that depends on when the order is shipped which is officially referred to as the shipping date.

However, the date of shipping is not the same as the date of order placed or the estimated delivery date. Let’s understand how.

What is a Shipping Date?

As the name suggests, the shipping date is when an eCommerce company hands over an order to the carrier for delivery to the customer, which is the day that the shipment leaves the warehouse.

The transit time is calculated from the date of shipping. For instance, if the shipment takes two days to reach the customer and leaves the eCommerce company’s warehouse on the present day, it then becomes the shipping date. The next important tracking date is the estimated delivery date.

What is a Delivery Date?

The estimated delivery date is the day that the order reaches the end customer. Providing this information is crucial because most customers confirm the order only when they agree with the estimated delivery date. If an online retailer takes more than the desired time to deliver a shipment, the customers often abandon the cart. And if they are okay with the estimated delivery date, they check for status updates frequently.

6 Important Terms Related to Shipping Date & Estimated Delivery Date

Every discussion on shipping dates and estimated delivery dates contains a few unique terms. Below is a list of the most common ones:

Order Date

It is the date on which a customer confirms an order on an eCommerce website. It could be a pre-paid or COD order. This date triggers the retail logistics process for the shipment. It is when the product usually gets picked up by the seller. Most companies push for same-day pickup. But timelines can change if the customer places the order late at night or at some other odd hour.

However, an order date could be different from the shipping date. Many companies don’t ship on public holidays or have shipping cut-off times. People can view the shipping notifications in their track your order section.

Invoice Creation Date

It is the date on which an invoice is generated. Invoices are documents containing critical information about the purchase that enables the online retailer to receive their payment. Invoices generally include the following details:

  • Ordered products and their costs
  • Total amount due, including taxes
  • Seller and customer’s information
  • Payment information, including the method of the transaction
  • Delivery details

Estimated shipping date

This is the expected date that the order will leave the warehouse or fulfillment center and the shipping process gets initiated. It depends on:

  • Time of order placement: If the customer confirms an order at 11 pm instead of 11 am, it can add a whole day for the pickup.
  • Shipping cut-offs: Every company has their shipping cut-offs, which usually fall late in the evening and maybe over weekends and public holidays. An order cannot be pushed out of the seller’s warehouse if placed after the shipping cut-off.

Some companies display their shipping cut-off timings on the checkout page. Statements like “Orders placed after 6 pm IST will be shipped the next day.” condition the customer on when they can expect to receive the order.

  • Other factors: Many factors like public and bank holidays and strikes often cause a transport stall and affect the estimated date.

Estimated Delivery Date

Estimate delivery date refers to the expected timeline for delivery. The estimated delivery date is the date on which customer can expect to receive their order. The checkout counter displays this date and deeply affects the customers’ reaction to the delivery process. Longer estimated delivery dates often lead to cart abandonment.

This date gets depicted as a window between two dates such as June 1-3rd. Like the date of shipping, the estimated delivery date depends on various factors. The time of order confirmation and elements such as public holidays or national strikes affect the delivery. Moreover, since the carrier takes charge of delivery, their performance affects the distribution timelines. Any lag in their transportation cycle can push the estimated delivery date even further.

Shipping Speed

It is not the velocity, but the time it takes for a carrier to deliver the order to the customer. It describes a couple of things:

  • The time duration for delivery such as 3-5 business days
  • The shipping method such as express or standard delivery

The shipping speed is also affected by carrier performance and environmental influences, including political and economic scenarios. For international shipments, the regulations affect the shipping speed. For example, if the consignment gets stuck in customs for days, the shipping speed reduces, and delivery timelines expand. Plus, many customers agree to pay more to enhance the shipping speed. There are certain sellers and platforms providing free shipping options too.

Return date

When a customer is unhappy with the product, they place a request to return it to the seller within a set timeframe, which is also known as Return to Origin (RTO). The carrier collects the shipment from the customer and returns it to the eCommerce company’s warehouse or directly to the seller. The return date is the day on which the specified items return to the origin.

It is different from the return window, which is the timeframe given to customers to place the return request. For instance, products with a 30-days return policy are eligible for return to the seller within 30 days of delivery to the customer.

7 Important Factors Affecting Shipping Dates in 2024

Shipping Dates are timeframes that can be affected by a variety of external influences. Here’s a list of major factors for 2024 that impact its calculation:

Lead Time

It is the time between order placement and the shipping date. It depends on the type of product ordered. Lead or production times for products that are ready to be delivered are shorter than those that need manufacturing or assembly before shipping.

Backorders, inventory shortages, or issues in procuring raw materials for a large number of orders affect the readiness of the final product and hence the date of shipping.

Shipping Cut-Offs

Also called cut-off fulfillment timelines, shipping cut-offs also include inventory procurement or manufacturing timelines for every order placed before shipping. It can specify the time of day or the actual dates. For instance, production for orders placed on December 25th will resume on January 2nd.

Manpower Availability

There are various steps involved before the order is ready for shipping. The absence or inadequacy of the workforce leads to delays in order processing which also affects it.

Transit Time

The time spent in transit affects the shipping date. It depends on the carrier, their performance, the shipping mode (express or standard), mode of transport, and the destination.

Natural Disturbances

Sudden weather changes can disrupt transportation causing the shipment to sit idle in the warehouse. For example, heavy rainfalls cause significant traffic jams, and heat or cold waves can cause health issues among delivery personnel. Ultimately, these disturbances can lead to delayed shipping dates.


When inventory needs to be procured from another state or country, the domestic and international regulatory authorities influence the rolling out of the shipment from the seller’s location. And if the load needs to go through layers of regulatory procedures before reaching the customer, the shipping date needs to be preponed to ensure timely delivery.

For example, if a shipper needs to expedite a shipment that needs to leave India and reach the customer in the US ten days later, the seller will have to keep some buffer to successfully clear international customs which affects the shipping date.

Political and Economic Scenarios

This scenario at either the origin, destination, or both can affect the shipping date. Moreover, any local or public holidays, people protesting on roads, and union strikes affect the distribution and ecommerce shipping timeline.

For instance, if the destination faces disruption due to political activity, order shipping from the warehouse will have to be stalled, thus delaying the date of shipping.

Which Factors Should be Considered While Calculating the Estimated Delivery Date?

The estimated delivery date depends on the following factors:

  • Origin and Destination: The further away from the destination, the longer it takes to get the shipment to the customer’s doorstep.
  • Route Condition: For instance, if an order needs to reach a tier 4 town from Mumbai, the estimated delivery date depends on the number of tolls and road conditions.
  • Product Details: Large quantities take more time to deliver. Plus, inventory procurement from afar leads to delayed timelines.
  • Average Transit Time: The transit duration for previous similar orders fulfilled by logistics companies should be calculated to get a better idea of the estimated delivery date.
  • Estimated Shipping Date: Delivery depends on when the order gets shipped from the warehouse. Any delay there snowballs into delayed delivery to the end customer. It also means the ESD has an impact on the delivery date.
  • Shipping Mode: Express and standard modes offer different delivery timelines. The option selected by the customer decides how fast the delivery will occur.
