About Perk by Kate
Kate Low runs Perk by Kate out of Singapore. The store has been on Shopify since October 2011, it's on Shopify Plus now, and it ships all over the world.
Most people who land on the site have never heard of the brand. They're often a long way from Singapore, looking at a price in a currency they don't use, and they make up their mind about the store pretty quickly.
Before Vitals: eight apps, eight bills
So the store needs a few things on the page. Reviews. Prices in the shopper's own currency. Payment logos, a buy button that stays in view, an Instagram feed, a chat button and a note in the cart.
On Shopify, each of those is usually a separate app. That's eight apps for Perk by Kate, and every one of them comes with its own monthly bill, its own code loading on every page, its own dashboard and its own support team to email when something breaks.
We measured the load times in our own speed test on a sample product page, not on perkbykate.com.
After Vitals: eight apps, one bill
Perk by Kate has been on Vitals since August 2023, and all eight of those apps now come with one Vitals plan at $29.99 a month. Each app is a switch in the Vitals dashboard, and turning another one on doesn't mean installing anything or paying more.
Day to day, that means one bill, and one app loading code on each page instead of eight. Changes happen in one place, and there's one support team to ask. Review requests also go out on their own, so the store doesn't need a separate email tool for them.

- Product Reviews
Star ratings show next to the price, and the full reviews sit lower down the product page, each one tagged as a verified buyer. The store has 351 reviews with a 4.96 average, and 340 of them are five stars. Vitals asks for the reviews too. Once an order is delivered, it emails the customer. In the last 90 days it sent 3,025 of those emails and 1,683 were opened, which is 56%. Nobody at Perk by Kate writes or schedules them.
- Shoppable Instagram Feed
The brand's Instagram posts show on the homepage and on product pages. A shopper who has never heard of Perk by Kate gets to see real people wearing the pieces before they buy.
- Payment Logos
Since September 2026, the cards and payment options the store accepts show under the Add to Cart button and again in the cart, local payment methods included.
- Currency Converter
Prices change to the shopper's own currency based on where they're browsing from, so someone in Texas sees dollars and someone in Manchester sees pounds. The store has 160 currencies turned on.
- Sticky Add to Cart
The Add to Cart button stays on screen while shoppers scroll through photos and reviews. They never have to scroll back up to buy.
- Cart Notice
A short message in the cart tells shoppers anything they should know before they pay. The store writes it once and everyone sees it.
- All-in-One Chat
One chat button links to the messaging apps the team already replies on, so a shopper with a question doesn't have to email and wait.
- Auto External Links
Links to other sites open in a new tab. A shopper who clicks through to Instagram still has the store open behind it.
Apps Perk by Kate could replace next with one Vitals plan
Perk by Kate uses 8 of the 40+ apps in Vitals. If the store wants a size chart, bundles or a wishlist, it doesn't need another app for them. Every other app is part of the same Vitals plan and sits in the same dashboard, ready to turn on. These four would suit a clothing store that sells overseas:
Each one is a switch in the same dashboard. No new app, and no new bill.
“I do like Vitals, and I recommend it to quite a few of my friends.”
