The platform debate shows up before anyone has counted the pages.
Webflow or custom code?
Nobody has mapped the CRM. Nobody knows who owns the site after launch. The content inventory is a folder called FINAL-FINAL-2.
But sure. Let's argue about the tool.
Start with the job
A marketing website has to explain, prove, route, capture, and help the team publish. Webflow can do that well when the content model is clean and the interactions stay inside the platform's real limits.
A software surface has to manage state, permissions, user-specific data, transactions, or product behavior. That work often earns custom code.
The trouble begins when a company buys custom engineering for a marketing site because freedom sounds good. The same trouble appears in reverse when Webflow gets forced to behave like an application through twelve workarounds and a prayer.
The cheaper build can create the expensive website
Implementation is one line in the cost.
Who fixes dependencies? Who monitors forms? Who can publish a case study without filing a ticket? What happens when the one developer who understood the CMS leaves?
Custom code can be the right choice and still be the wrong operating model.
Webflow can be less expensive and still fail if the site needs behavior it was never built to carry.
You are choosing the maintenance burden too.
Migration is where the bodies are
The redesign gets approved around new pages. The actual risk sits in the old ones.
URLs disappear. Redirect maps miss the long tail. Analytics resets. Forms stop routing. Years of search equity get folded into a spreadsheet nobody checks after launch.
That work does not care whether the new homepage came from Webflow or React. It cares whether somebody treated the existing website like a working business system instead of a pile of old design.
Ask the team that stays
The build team gets six months. Your marketing team gets the next four years.
Put them in the platform decision.
Can they create a page without breaking the system? Can governance live inside components instead of a training deck? Can the site connect to the tools they actually use? Is the backlog owned after launch?
If the answer depends on a future hire, price the future hire.
The website systems service starts with scope, risk, and ownership before the tool gets a vote. The platform gets easier once the job is honest.
