Most websites do not need to be built separately. The rest cannot avoid being built separately. The issue is knowing which group you belong to.
Pre-built foundations (website builders or existing CMS like Webflow, WordPress, Shopify) are sufficient for most basic promotional and sales websites, as long as the tasks remain within common templates. Custom builds should only be considered when the site needs to perform a task that templates cannot handle: specific conversion flows, internal system integrations, very strict speed thresholds, or very large content scales. Do not build custom just because it sounds more sophisticated, as the costs and time invested will not be proportional if the actual needs fit within a template.
This is a question that Sinh Vũ frequently hears, and the answer is mostly: pre-built is sufficient. It’s not that custom builds are inferior, but because most small and medium-sized business websites do not actually need to go beyond the template. The issue is that you need to know how to ask the right questions to determine which group you belong to.
Before asking "what platform should we use?", ask: what does this page need to accomplish that common templates cannot? If you do not have a clear answer to that question, it is likely that the page will still fit within a template, and a pre-built platform is a reasonable choice.
Pre-built foundations (website builders or CMS, meaning content management systems, available like Webflow, WordPress, Shopify) are suitable when you need to launch quickly, keep initial costs low, and allow non-technical users to edit content later. This is the reasonable default choice for most small and medium-sized businesses.
You can confidently use the pre-built platform in the following cases:
In these cases, a pre-built platform is not a second choice; it is the right choice. The budget saved can be allocated to content, imagery, and optimizing the conversion flow (the process customers go through from viewing to purchasing or contacting), which yields much more tangible results than building a complex technical system.
Custom building (meaning the technical team writes code from scratch without relying on intermediary platforms) is only worth investing in when at least one of the following conditions is met:
Custom building provides complete control and allows for clean HTML (the structure language of websites) according to your preferences, which benefits technical SEO (optimization for search engines). In return, you need a capable technical team, a higher budget for both building and maintaining after handover, and a longer implementation time.
Sinh Vũ sees two recurring mistakes at two opposite ends:
Sinh Vũ clearly separates three levels for clients to choose according to their actual capacity:
The foundation is a means, not an end. The right question is what the site needs to accomplish, not what the site is built with.

You do not need to understand the technical details to make the right decision. You just need to clearly and specifically describe what the page needs to do. From there, the choice of platform will become apparent.

No. Webflow and WordPress are both pre-built platforms, meaning you are using an existing system and customizing it. Custom build means the technical team writes code from scratch, without relying on any intermediary platform. Most small and medium-sized businesses do not need to go to that extent.
Sinh Vũ does not provide a market comparison number because it varies greatly depending on the team and features. What you need to know is that building something custom incurs higher costs both during the creation phase and after delivery, as every change requires technical intervention. Pre-built solutions allow non-technical users to edit content themselves, which is a practical operational advantage.
Yes, but it often requires starting over instead of directly converting. That’s why Sinh Vũ advises you to clearly define what the page needs to do from the beginning, to choose the right threshold and avoid paying twice.
