The best Shopify apps – must-haves for your online store 🚀

The best cookie banner for Shopify – super easy to customize and fully GDPR-compliant. For me, it's a no-brainer and belongs in every store, no discussion needed.

An absolute must-have! This app automatically syncs tracking numbers and shipping carriers to your PayPal Business account. It helps reduce the risk of PayPal holding your funds or freezing payments – which can easily happen when your revenue grows quickly and can be seriously frustrating.

Klaviyo is by far the best email marketing software for Shopify in my opinion. It allows you to dive deep into automation with targeted flows, smart segments, and A/B testing. If you're serious about your store, Klaviyo can easily generate 20–30% more revenue through email alone.

Reviews are key to building trust – and Reviews.io is my go-to solution. You don’t just get star ratings under your products, but also beautifully designed widgets for your homepage, product pages, and even the checkout. Bonus: It integrates directly with Klaviyo for automated review flows.

Sufio is my go-to automated invoicing solution for international stores. It automatically creates legally compliant invoices in over 40 languages, supports EU VAT validation, and integrates directly with Klaviyo and Recharge. Trusted by 7,300+ Shopify merchants worldwide.

Billbee is a solid starting point for invoicing if you're running a small store in the DACH region. The Shopify integration works well and it pairs nicely with accounting software like Lexware Office. That said, Billbee comes with a lot of extra features like warehouse management that most Shopify stores simply don't need – and costs can add up quickly as your order volume grows. Once you're hitting 50–100 orders per month, I'd recommend switching to Sufio instead.

If you’re still handling shipping yourself, Sendcloud is a must. It lets you create shipping labels in seconds, connect your DHL, GLS, DPD, UPS & FedEx business account, and saves you tons of time and hassle. Especially in the early stages, it’s a huge relief – also great for handling returns and tracking.

This app gives you real insights into your business – far beyond basic revenue tracking. You’ll see exactly how much profit you make per product or customer, helping you make smarter business decisions. Especially valuable for smaller stores just starting out.

Zigpoll lets you run post-purchase surveys directly after checkout – perfect for finding out where your customers came from, what almost stopped them from buying, and why they converted. You can use those insights to optimize your marketing strategy, refine your messaging, and improve your ROAS. Super powerful if you want to stop guessing and start making data-driven decisions.

I mainly use this app to efficiently compress images, convert them to WebP, and significantly reduce file sizes. Images are often the biggest performance bottleneck in a store – and this app helps you achieve ultra-fast loading times without manually editing each file. As a bonus, you can also bulk-edit filenames and ALT texts if needed.

If you have a large product catalog, you definitely don’t want to update everything manually. This app makes bulk editing a breeze – whether it's prices, titles, inventory, or tags. Once you’ve used it, you won’t want to work without it.

Incorrect or incomplete addresses are a common cause of returns and extra support work. AddressHero checks address entries right at checkout and alerts customers if something’s wrong. This helps you avoid failed deliveries, unnecessary customer service, and extra costs.
