How they work

Sleek Infosolutions follows a seven-stage process: Planning, Define Requirements, Design & Prototyping, Development, Testing, Deployment, and Maintenance. In the Planning phase, the team meets with clients to understand goals and conduct competitor analysis. Requirements are then documented in a scope of work to align both parties before development begins. Design and prototyping includes unlimited revisions until approval. Development converts designs into functional applications. Testing involves both internal review and user acceptance testing (UAT) with client sign-off before launch. Deployment includes hosting setup and going live. Post-launch, the company provides maintenance and change management.

The company emphasizes regular communication during development and states that projects are flexible to accommodate future business growth. No specific pricing model, contract terms, or engagement duration is mentioned in the source material.
