Hi Rachel,
Thanks for your post!
It's really hard to pick the best app! There's so many in their respective categories that can be really useful and in some case "must-haves".
Some key apps that I often encounter with merchants include, but not limited to:
- Mailchimp - for emails and email marketing
- Order Printer - print invoices and receipts and packing slips
- Free Shipping Bar - notify your customers of Free Shipping with a banner
- Better Coupon Box - Popup a coupon box to convert visitors into social fans, followers,... and increase your sales. You can actually use this for your first time customers! And I think that's a great idea. Give your new customers a welcome discount!
For a more general list of our most popular apps, check out this link.
Let me know if you have any questions on the above, or if you're looking for a particular app in a specific field (sales, marketing, accounting, social media, etc.).
Take care!
Johnny Shopify
