Frequently Asked Questions
How long does it take to build a web application?
Simple applications typically take 2-3 months, whilst complex platforms require 4-6 months or longer. Timeline depends on features, integrations and complexity. We provide detailed schedules during discovery.
How much does custom web application development cost?
Web applications typically range from £20,000 for simple tools to £100,000+ for complex SaaS platforms. Investment depends on features, complexity, users and integrations. We provide transparent pricing based on your specific requirements.
What’s the difference between a website and a web application?
Websites primarily display information and content, whilst web applications allow users to interact with data, perform tasks and manage workflows. Think of it as the difference between reading a brochure (website) and using software (web application).
Can you integrate with our existing systems?
Yes. We specialise in integrations with CRMs (Salesforce, HubSpot), accounting software (Xero, QuickBooks), payment processors (Stripe, PayPal) and virtually any system with an API.
Do we own the code you write?
Yes. Upon final payment, you receive full ownership of all custom code, designs and intellectual property created specifically for your project.
What happens after the application launches?
We offer ongoing support, maintenance and enhancement packages. Most clients retain us for security updates, performance monitoring, bug fixes and feature additions as their business evolves.
How do you ensure the application is secure?
Security is built in from the start: secure authentication, encrypted data transmission, SQL injection prevention, XSS protection, regular security audits and compliance with OWASP guidelines.
Can the application scale as we grow?
Absolutely. We architect for scalability from the beginning using cloud infrastructure, load balancing, caching strategies and database optimisation that scales from hundreds to millions of users.
Do you provide training for our team?
Yes. We provide comprehensive admin training, user documentation and ongoing support to ensure your team can manage and maintain the application effectively.
