This article is all about my experience so that from scratch you can master this "steed" of the Flatsome Theme, building a genuine and professional online sales website yourself.
What is the Flatsome theme that is "making waves" in the Vietnamese online sales world?
Theme Flatsome is a specialized WordPress theme for e-commerce, developed by UX Themes and is currently the best-selling theme on ThemeForest in this field. It provides a complete ecosystem that helps users create professional online sales websites without knowing how to code.
At Pham Hai, we have implemented hundreds of projects and realized that Flatsome's true strength lies in its perfect combination with the e-commerce ecosystem. If you're new, learning what is woocommerce is an important first step in understanding how to manage products, orders, and payments on the platform. The deep compatibility between Flatsome and WooCommerce makes every sales process extremely smooth.

"Rocket" page loading speed and available SEO optimization - Money-making factors to get to the top of Google.
The SEO-standard Flatsome theme is programmed with a minimalist source code structure, eliminating redundant files, helping to achieve optimal page loading speed right from the moment of installation. At the same time, the interface is designed to be 100% compatible with Google search engine ranking and data collection guidelines.
Page loading speed is a vital factor for a sales website. Customers will lose patience and leave if the website takes more than 3 seconds to display. Fortunately, the advantage of Flatsome Theme is the built-in ability to lazy load images and extremely good CSS/JS optimization. Of course, to achieve an absolute performance score, you should also apply in-depth Woocommerce speed optimization to coordinate smoothly with the interface.
Furthermore, Flatsome responsive automatically adjusts for perfect display on all screen sizes from desktop computers, tablets to mobile phones. This mobile friendliness not only brings a smooth shopping experience to users but is also a mandatory criterion for Google to prioritize ranking your website higher than your competitors.
Huge demo interface repository and deep WooCommerce integration - Open an online shop in just a few clicks.
Flatsome Studio provides a huge library containing hundreds of website templates and pre-designed blocks (demo content), allowing you to import the entire interface with just a few basic operations. Along with that, this theme is structured as a "perfect puzzle piece" for the WooCommerce plugin, helping to automate sales.
When designing a sales website with Flatsome, you don't have to face the fear of starting from a blank page. You just need to open the Studio library, choose an interface template suitable for your industry (fashion, furniture, electronics...), click import and change the content and you immediately have a professional online shop.
The ability to deeply integrate with WooCommerce is clearly shown in the following features:
- Tùy biến linh hoạt: Dễ dàng thay đổi bố cục trang danh mục, chi tiết sản phẩm, giỏ hàng và thanh toán mà không sợ bị vỡ giao diện.

Instructions for installing Flatsome Theme from A-Z for beginners (Actual images included)
The Flatsome installation process starts from preparing the web environment, downloading the standard installation file, activating the license and setting up basic steps through the built-in Setup Wizard. This process is designed step by step to be very intuitive, helping new users not be confused or encounter technical errors.
Even though this is a Flatsome Theme for beginners, you still need to follow the correct order and principles to avoid minor errors later. At Pham Hai, we always encourage customers to be careful from choosing the source to buy the theme to configuring the child theme to ensure the website operates durably.
Where to buy copyright Flatsome Theme? Quick comparison between buying on Themeforest and other sources.
To ensure maximum safety and receive the latest updates, you should purchase the copyrighted Theme Flatsome directly from the ThemeForest application market at the current listed price of 59 USD (updated in 2026). Downloading or buying from cheap floating sources can pose huge security and malware risks.
Many new web users often wonder about the price of Flatsome Theme and try to find free "nulled" (cracked) versions online to save costs. I sincerely advise you absolutely not to. Below is a breakdown for you to clearly see the difference:
| Criteria | Buy on ThemeForest ($59) | Floating/Nulled source |
|---|---|---|
| Bảo mật | 100% clean, absolutely safe | High risk of installing viruses and backdoors |
| Cập nhật | Automatically, receive the latest version for life | Manual, often outdated, website crashes |
| Hỗ trợ | 6 months of direct support from the author | There isn't any technical support |
Investing $59 for Flatsome license is the cheapest and smartest investment to protect your "bread and butter" on the internet for the long term.
5 steps to install Flatsome Theme and accompanying plugin on WordPress website.
The installation process includes downloading the original file from ThemeForest, uploading it to the WordPress dashboard, activating the theme with the license key, and running the setup wizard to install the required plugins.
Before starting this Flatsome Theme Installation Guide, make sure you have rented a quality hosting package, successfully pointed your domain name, and pre-installed a brand new copy of WordPress. Below are 5 detailed steps:
- Tải Theme Flatsome: Đăng nhập vào tài khoản ThemeForest của bạn, đi đến mục Downloads. Tại dòng Flatsome, bấm nút Download và chọn tải "Installable WordPress file only" cùng với file "License certificate & purchase code" (dùng để kích hoạt).
- Upload Theme lên web: Truy cập vào giao diện quản trị WordPress Admin > Giao diện (Appearance) > Thêm mới (Add New) > Tải giao diện lên (Upload Theme) và chọn file .zip vừa tải về ở bước 1.
- Kích hoạt: Sau khi tải lên hoàn tất, nhấn nút "Kích hoạt" (Activate). Ngay lập tức, màn hình chào mừng Setup Wizard của Flatsome sẽ hiện ra để dẫn dắt bạn.
- Nhập mã bản quyền: Mở file License đã tải, copy đoạn mã Purchase Code và dán vào ô yêu cầu trong Setup Wizard để xác thực bản quyền chính hãng.
- Cài đặt Plugin & Demo: Tiếp tục bấm "Continue" qua các màn hình. Hệ thống sẽ tự động đề xuất cài đặt các plugin thiết yếu như WooCommerce, Contact Form 7. Ở bước cuối, bạn có thể chọn import một giao diện mẫu (demo content) để bắt đầu nhanh hơn.
Activate Child Theme - Important step to avoid "losing everything" when updating.
Child theme is a sub-interface that inherits all the features and style of the original Flatsome (Parent theme), giving you the freedom to add custom code that will not be lost when updating to a new version of Flatsome in the future.
While running the Setup Wizard above, the system will automatically ask if you want to create and activate a Child theme. My advice is: Always choose "Yes".
Nếu bạn bỏ qua bước này, sau này khi bạn tùy biến giao diện Flatsome bằng cách chèn thêm các đoạn code CSS hay PHP vào file functions.php của theme gốc, mọi công sức của bạn sẽ "bay màu" sạch sẽ ngay khi bạn nhấn nút cập nhật Flatsome lên phiên bản mới. Child theme sinh ra chính là chiếc khiên bảo vệ những tùy chỉnh cá nhân hóa của bạn.
Master the most important customizations in Flatsome to make your mark
To Optimize Flatsome Theme and turn it into a website with a strong personal or business brand identity, you need to become familiar with two core tools: Theme Options (used to customize the overall page settings) and UX Builder (used to design the detailed layout of each specific page).
Flatsome's template interface is very nice, but if everyone uses the same default settings, your website will look very generic. Let's dive into the most important customization steps to make a difference.
Customize Header & Footer: Logo, Menu, contact information professionally.
Flatsome provides an extremely intuitive drag-and-drop Header Builder located in the Appearance > Customize section, allowing you to freely arrange your logo, navigation menu, search bar and shopping cart icon with just simple mouse movements.
Customizing the header is the first and most important step in shaping brand identity. In Header Builder, the space is divided into 3 distinct floors: Top bar (contains small contact information), Main (contains logo, main menu) and Bottom (contains sub-categories). Customizing the header makes it easy to upload a logo, change the main color of the navigation bar, and set a consistent font for the entire website.
For footer customization, you have two ways: use traditional WordPress Widgets or use the UX Builder itself to design a beautiful UX Block and then assign it as the default Footer. In this area, make sure you provide all contact information, purchasing policies, Ministry of Industry and Trade certification and social network links to increase the store's credibility.
Use UX Builder to design homepages and sales landing pages that "hypnotize" customers.
To create an impressive homepage or landing page, you just need to create a new page in WordPress, press the "Edit with UX Builder" button, then use elements such as Banner, Slider, Row, Column and Product Grid to assemble a complete layout according to your intentions.
The home page is the front of the online store. By using the power of UX Builder, you can create borderless promotional banners with eye-catching parallax effects.
If you are running Facebook or Google ads, creating a separate landing page with Flatsome is also extremely quick. You can freely drag and drop customer review blocks (Testimonials), add countdown timers (Countdown) to flash sale programs to create a scarcity effect, thereby promoting a strong closing rate.
Customize product pages and carts with WooCommerce to increase conversion rates.
Flatsome allows you to change the entire layout of the product detail page (Product Page) and optimize the payment process (Checkout) right in the Customize > WooCommerce section, making the customer's shopping journey seamless and with the fewest barriers.
A cumbersome, difficult-to-operate product page will directly kill your sales. In this Customization section, you can set the product image layout on the left, price information and buy button on the right for UX standards. You can also enable "Upsell" or "Cross-sell" blocks to increase the average value per order.
In particular, Flatsome supports a very smart Off-canvas cart feature. When a customer clicks add to cart, a cart bar slides out from the right edge of the screen instead of reloading the entire page. This gives a very modern shopping feel and keeps customers on the product page longer.
In short, with my real-life experience, Flatsome is not simply a theme, it is truly a powerful business tool for anyone who wants to start an online sales business. Don't hesitate to invest in the license, because the values it brings from page loading speed, infinite customization capabilities to excellent SEO support will help you save countless time and maintenance costs later. Just be bold and deploy it, my friend, this "steed" will definitely not disappoint you.
