Realistic timelines by project type, and the specific things that push a launch date back.
Timeline questions usually get answered with a single number, "eight weeks," that quietly assumes everything goes smoothly. It rarely does, entirely without fault, because most delays come from the client side of the process, not the agency side. Here's what a realistic timeline actually looks like, broken into phases, along with what tends to add time.
A standard eight-to-fifteen page marketing site, from signed proposal to launch, typically runs six to ten weeks when content is ready and feedback comes back on schedule.
Ecommerce builds take longer because product catalogs, payment integrations, and shipping logic all need to be configured and tested, on top of the design and development work. A straightforward Shopify build with a modest catalog sits toward the shorter end. A large catalog with custom logic or subscription commerce sits toward the longer end.
Anything with accounts, dashboards, or a database behind it takes longer because there's genuine software engineering involved, not just page assembly. Timeline here depends heavily on feature count and how many external systems the application needs to integrate with.
This is the single biggest cause of timeline slippage we see. A project with a one-week feedback loop on design reviews takes measurably longer than one with a 48-hour loop, even though the actual design and development work is identical.
Waiting on copy or photography mid-project stalls development, because pages can't be finalized around placeholder content. This is exactly why our redesign checklist puts content readiness near the top of what to prepare before a project even starts.
Adding pages, features, or a platform change after development has started resets parts of the timeline, even when the change seems small from the outside. Locking scope before development begins is the most effective way to protect a launch date.
When feedback comes from multiple people with conflicting opinions and no clear final approver, review cycles multiply. Agreeing on a single decision-maker before the project starts, as covered in the redesign checklist, prevents this specific problem.
Waiting on API access, credentials, or responses from another vendor, your CRM provider, a payment processor, a booking system, can stall a project through no fault of either the client or the agency. Flagging these dependencies early gives everyone time to chase them down before they become blockers.

To a point. More resources can compress certain phases, but design and development both require sequential thinking that can't always be parallelized just by adding people. Rush timelines are possible but usually carry a premium.
With content fully ready and fast feedback turnaround, a small marketing site can sometimes launch in four to five weeks. This is the exception, not the average, and usually requires everything else in this article to go right.
Sometimes, if a meaningful amount of existing content and structure can be reused. Often it takes about the same amount of time, since a proper redesign still goes through discovery, design, and development, just with more existing material to reference.
