How much does custom web application development cost?
Cost depends on feature scope, integrations, and platform choice. A simple internal tool costs far less than a multi-tenant SaaS product. We provide a cost estimate after reviewing your requirements during feasibility.
Can you migrate our existing web application to the cloud?
Yes. We assess your current architecture, plan a migration path to cloud infrastructure, and move the application with minimal downtime, then optimize it for the scalability and cost model of the new environment.
Do you build on WordPress, Drupal, or a fully custom stack?
Both. We customize CMS platforms such as WordPress, Drupal, Joomla, and Sitecore when a content-driven site fits your needs, or build a fully custom stack with React, Next.js, or .NET when the product needs more flexibility.
How long does it take to build a SaaS web application?
A focused MVP typically takes 3 to 5 months, while a full-featured multi-tenant SaaS platform can take 6 to 12 months. Scope, integrations, and team size are the main factors that change the timeline.
Can you integrate our web app with third-party APIs and payment gateways?
Yes. We regularly integrate payment gateways, CRMs, analytics platforms, and other third-party APIs into web applications, and we test each integration for reliability before release.
Do you provide maintenance after the web app launches?
Yes. Ongoing support covers bug fixes, security patches, performance monitoring, and feature updates, so the application keeps working reliably as your user base and requirements grow.
