# How do I add historic Product Costs from Shopify into my dashboard

> How to backfill historic Shopify product costs (COGS) so gross profit and LTV metrics reflect accurate margins.

## In this article we discuss Historical Product Costs for Shopify

### Requirements

* Inserted **product costs** on the **Financial Cost - Product COGS** tab on the configuration sheet

### Background

Keeping track of `product costs` is crucial for your business. It is a significant expense that directly affects your profitability at the customer, order, and product levels and is included as part of our COGS (Cost of Goods Sold) and Gross Profit metrics.

### Steps

1. Input your **Historic Product Costs** within your **Configuration Sheet**

   * Go to the **Financial Cost - Product COGS** Tab
   * Enter the below:
     * category = Financial
     * sm\_channel Online DTC
     * expense\_channel = Product COGS
     * SKU
     * product cost - *This is your cost per product*
     * date\_start
     * date\_end <br />

   *Note: date\_start and date\_end can be used to capture changes in product costs over time. You will be able to change these date fields historically and in the future in case of updates to product costs and our data model will update accordingly.
   It is imperative to make sure you include a date\_end date as the row will not be included if there is not date\_end included.*
