Frequently asked questions
- How long does it take to complete a B2B / Professional Services website?
Every website project is unique. Our commitment is to deliver on schedule and within budget. We establish a clear project timeline with defined stages and assign a dedicated project manager to ensure smooth progress. Typically, stakeholder research, reporting, design, and testing take between one to two months, varying with project complexity. Full development, hosting, and launch may extend the timeline to 3-6 months. Prompt provision of required materials like images and information from your end helps us minimise delays.

Our website projects typically range from £20k to £100k, tailored to your specific needs. While we may not offer the lowest rates, we take pride in our industry leadership spanning over 23 years. Our process integrates thorough research to optimise your website for conversions and deliver a seamless user experience, trusted by B2B leaders such as MBL Seminars and EcoAct. With Contra, you receive exceptional value that aligns with your investment goals.
