Content readiness, feedback speed, and revision cycles also affect the timelines. eCommerce platforms or custom web applications can extend to 3-6 months or more due to testing, optimization, and deployment requirements.
What happens after a website development project finishes?

They also hand over credentials, documentation, and training so your team can manage the site confidently.
