Our HTML5 development capabilities include interactive user interfaces, reusable components, API integrations, form workflows, cross-browser testing and performance optimization. We can modernize existing HTML5 applications or engineer new web experiences around your requirements.
HTML5 Mobile Web Applications
For mobile-friendly applications, we build responsive browser-based interfaces and can evaluate progressive web app features such as installability and offline support where appropriate. Native mobile applications remain a separate implementation choice.
Frequently Asked Questions
Real cost ranges, real timelines, real answers — everything a founder or product lead needs before starting a B2B web development project with us.
How much does web development cost for a B2B platform?
Costs range from $15,000 for a standard single web application to $250,000+ for an enterprise SaaS platform. Mid-complexity builds (client portal, custom backend) run $40K to $120K over 4 to 8 months. Enterprise platforms with multi-tenant architecture or compliance requirements: $120K to $250K+ over 6 to 14 months.
How long does it take to build a B2B web platform?
Standard platforms take 2 to 4 months. Mid-complexity portals or dashboards: 4 to 8 months. Enterprise SaaS platforms: 6 to 14 months. Key factors are requirements clarity at kickoff, approval cycle speed, and integration complexity.
Do you build custom web applications or use templates?
We build custom-coded web applications and platforms, not templates or low-code tools. Every architecture, database schema, and integration is designed around your specific business workflow.
What is the difference between a website and a web application?
A website presents information. A web application lets users log in, interact with data, and complete workflows, think client portals, dashboards, and SaaS products. We specialize in the latter: custom, logic-driven web applications for B2B businesses.
What does your development process look like?
Six stages: Discovery/Scoping (1 to 2 weeks), UX/UI Design (2 to 4 weeks), Agile Development in 2-week sprints (8 to 20 weeks), QA/Testing (2 to 4 weeks), Launch & Deployment (1 to 2 weeks), and ongoing Maintenance. Each stage ends with a client deliverable and sign-off.
Do you sign NDAs before project discussions?
Yes. We sign a mutual NDA before any scoping conversation, on request, at no charge. Your business logic, data, and requirements stay fully confidential throughout the engagement.
Can you integrate our platform with our existing CRM, ERP, or other tools?
Yes. We regularly build integrations with Salesforce, HubSpot, SAP, Stripe, and other B2B systems using REST, GraphQL, and webhook-based architecture.
What post-launch support do you offer?
Monthly retainer or per-project basis: security patches, bug resolution with defined SLAs, performance monitoring, and optional iterative feature development. We recommend a minimum 3-month post-launch engagement.

Custom Web Development
vs WordPress
Both approaches can power a successful website, but they serve very different goals. Here is an honest, side-by-side comparison to help you decide which path fits your business, budget, and growth plans.
Choose Custom Web Development If
- You are building a SaaS product, B2B platform, or client portal with complex workflows.
- You need deep integrations with ERP, CRM, payments, or internal systems.
- Security, compliance (GDPR, SOC2), and scalability are business-critical.
- You want full code ownership and a platform that grows with your roadmap.
Choose WordPress If
- You need a content-first marketing site, blog, or brochure website.
- Your requirements are standard and well covered by existing themes and plugins.
- Budget is limited and speed to launch matters more than custom functionality.
- Non-technical teams will manage content updates day to day.
Our recommendation: start with the problem, not the platform. If your website is a marketing asset, WordPress is often enough. If it is the product itself or central to how your business operates custom web development pays for itself in performance, security, and long-term flexibility.
