We plan, staff and run the project from start to release. You review demos and accept the work against the agreed scope.

Team size and setup depend on the job. These are real engagements, each tied to the client who hired us.

White-label work starts under NDA. We do not name agency clients or their end clients without permission, which is why this one appears here anonymously.

What it costs to build a SaaS product: hours and budgets for an MVP, a v1 for paying B2B customers and a scaled platform, cost per feature (multi-tenancy, billing, SSO, admin, onboarding, analytics) and the fees you pay after launch.
A web app costs about $9,000 for a simple internal dashboard to $480,000 for a large multi-tenant platform at Eastern European rates. We break down portals and dashboards by size and component, and show which features move the price.
Custom software costs about $14,000 to $320,000 at Eastern European rates and roughly twice that onshore in the US. We break it down by project type, component and engagement model, and show how to get an estimate you can plan on.

Yes. In white-label work we sign an NDA, build under your name and stay in the background with your clients. A US software consulting company used us this way from March 2021 to May 2025 for Umbraco sites and Okta integrations, and we assigned PMs and QA on our side when their projects needed it.
We agree acceptance criteria before work on a ticket starts. This came from client feedback: our white-label client told us their tickets worked best with very specific criteria and asked for more initiative from us in reading them. We now ask the questions up front instead of waiting for a review.
