# Option B: In-House

Merchants who have an in-house Apparel21 expert have the capability to independently configure the Apparel21 exports. Nonetheless, there are certain steps in which our involvement is still necessary. Please refer to the details below:

### Setup Process

* [ ] Provide the SFTP details for the instance
* [ ] Set up the CSV data exports
* [ ] Setup the required tasks to extract the data on a regular interval
* [ ] Upload example **customers,** **orders,** or **rewards** CSV exports (with all required fields) to a test folder
* [ ] Review the files and check Klaviyo to confirm that all mappings are behaving as expected
* [ ] Once confirmed, trigger automated scheduled CSV exports to the live folder

{% hint style="info" %}
The CSV files must be set up as two or three separate files: 

1. Customers 
2. Orders 
3. Rewards

These files must includes all the necessary fields needed to sync to Klaviyo. Please note, customers should be uploaded before orders on the scheduled task.
{% endhint %}
