Hey there, @nabeelak
Bo here from Shopify Support!
Towards the end of your trial, generally on the last day, an option to extend your trial by a further 7 days should appear as a banner in your admin. If this option does not appear and you do require some additional time I would recommend reaching out to our support team directly. Additional trial time is limited to 14 days and will only be applied at the end of the trial. While we’re not able to provide account-specific support via the Shopify Community at this time, we’d be happy to continue assisting you through live chat, email, or callback. Please visit https://bit.ly/3cJkx8V and log in to your account to create a support request.
To get the most of your trial time I'd recommend taking a look at our Shopify webinars. These short tutorials take you through all the basics of creating a store such as adding products, variants, collections, theme changes, and pointing a domain to your store. You should be able to sign up here. We also have a fantastic YouTube channel that is jam-packed with how-to guides which you can view here.
As this is your first post in the Shopify Community I would like to welcome you! Welcome! I would recommend reading our guide on getting support from the Shopify Community here so you are best equipped when looking for support through these forum boards. I would also recommend taking a look at our introductory guide to Shopify here in our Help Center. The Help Center is packed with brilliant resources on everything Shopify-related to help you get started.
What is it that you are planning on selling with Shopify? I would love to know more about your business so that I can provide more specific resources to help you get started.
In the meantime, as you are getting prepared to launch your store soon I would definitely recommend taking a look at our Essential Shopify Store Launch Checklist before going live to make sure you don't miss anything. We also have this great Buyer Trust 101 post which goes through how to make your store more trustworthy to customers so that they will check out.
All the Best,
