Read case study03 / How we work
Weekly demos, written decisions and a live staging link. You always know what is done, what is next and why.
Days 1–5
A focused call, then a written brief. We map goals, users, constraints and the one metric that decides success.
Week 1–2
Flows and clickable screens before a single line of production code, so feedback is cheap and fast.
Sprints
Two-week sprints with a live staging link. You see working software every week, not a status report.
Go-live
Deployment, store publishing, analytics and a handover you can actually read.
Ongoing
Monitoring, improvements and marketing that brings users to what we built together.

04 / Why SATechWork
Your tech, worked right. We are a small, senior-minded team that cares about the details users feel and the numbers owners track.
You talk directly to the people writing your code. No account managers relaying messages.
Async updates, written decisions and overlap hours that fit Indian and international time zones.
Source code, servers, store accounts and ad accounts stay in your name from day one.
Small releases every sprint. Real feedback beats long specs that nobody reads.
Backend, apps, design and marketing under one roof, so launches don't stall between vendors.
Fixed scopes where possible, straight answers when something changes, and no surprise invoices.
05 / FAQ
Anything else? Ask us directly. We usually reply within a few hours on working days.
We are a remote-first team of developers, designers and marketers. We do not run a physical office. We work with clients across India and worldwide over video calls, WhatsApp and email.
You get a shared project board, a WhatsApp group or Slack channel for quick questions, and a weekly demo call or recorded walkthrough. Every decision is written down so nothing gets lost.
Our core hours follow Indian Standard Time, and we keep regular overlap hours for clients in the UK, Europe, the Middle East and the US.
It depends on scope. After a short discovery call we send a written estimate, either a fixed price split into milestones or a monthly sprint retainer for evolving products. You approve it before work begins.
Fixed-price projects are usually billed in milestones, starting with an advance. Retainers are billed monthly in advance. We share invoices for every payment.
A focused MVP typically takes six to twelve weeks. Larger platforms are delivered in phases, with a usable first release early and further features in regular sprints.
Yes. Source code, domains, servers, app store listings and ad accounts belong to you. We work inside your accounts or transfer everything at hand-over.
Yes. We offer maintenance plans that cover monitoring, updates, bug fixes and small improvements, plus larger feature work whenever you need it.
