Custom Software and Web Apps
Dashboards, portals, booking systems and customer platforms, designed around your exact workflow instead of forcing your team into someone else's software.
✦ Digital solutions agency
We build software that builds businesses.
Tell us the problem, and we build the system that solves it: a store that sells while you sleep, a dashboard that replaces a dozen spreadsheets, a platform customers enjoy using. Custom built, fixed quote first, delivered in phases.

Services
What we can build for you.
Every business has a different bottleneck. We do not sell packages off a shelf. We study how your business runs, then build the digital solution that fits it.
Business Systems (ERP and CRM)
The software a whole business runs on: sales, purchases, stock, accounts, staff and reports in one place. Our own Construct Khata is exactly this.
E-commerce and Online Stores
Stores that do more than look good: clear product pages, smooth checkout, online payments and cash on delivery, with orders and accounts behind it.
Websites
A fast, modern website is still where customers judge you first. Custom designed, mobile first, and built to turn visitors into enquiries and sales.
Product Builds for Startups
A working first version of your idea, launched to real users and grown in phases, so you never bet everything on version one.
Care and Growth
Software is not finished at launch. We keep it fast, secure and improving: updates, backups, small features and search work, month after month.
Our work
Real systems, not just pages.
A selection of what we have actually built and shipped. Every project here is live or in daily use, and the biggest one carries a full case study.
✦ Our own software product
Construct Khata
A complete ERP system for building material stores, designed, built and refined by Zelvvo: sales, purchases, ledgers, cashbook, stock, staff and reports in one system that a real shop runs on every day.
The problem: a shop owner had to check three places to know what was sold, what was owed and what was left in stock.
The build: every bill posts to the ledger, cashbook and stock at once, so the dashboard, daybook and reports always agree.
- Sales and purchase bills, with returns
- Party ledgers for payables and receivables
- Cashbook and daybook
- Stock and item ledgers, by yard
- Staff, roles and permissions
- Reports: trial balance, P&L and product profit
Built with React, Node, Express, Prisma and PostgreSQL.

Who we work with
Built for businesses at every stage.
A one-person startup and a fifty-person company have different problems. What they share is this: the right system saves them time, money or lost customers every single week.
Product startups
Founders with a new idea who need a working product, not a pitch deck. First version, pilot, then growth, in phases that match funding reality.
E-commerce and product brands
Sellers stuck in DMs, spreadsheets and marketplaces who need a real store, real accounts and a buying journey that does not leak orders.
Wholesale, retail and trading
Owners replacing registers, notebooks and memory with one system for stock, credit, cash and reports.
Clinics and service businesses
Bookings, customer records and follow-ups handled by a system, instead of a phone that never stops ringing.
Teams with manual processes
Any business where the same information is typed three times, or one person leaving would take the whole system with them.
Not on this list?
If your work runs on notebooks, spreadsheets and memory, we should talk.
Start a project →How it works
How a project runs.
A fixed way of working, so you always know what happens next, and what it will cost, before it starts.
1
Discovery
We learn how your business works today, where it hurts, and what the system must do. Honest answers, no jargon.
2
Solution plan and fixed quote
A written plan: what we will build, in which phases, at what fixed price per phase. Nothing starts until you approve it.
3
Design and build
We design and build it ourselves. You follow along on a live preview link, not screenshots.
4
Review together
You use the real thing, we revise in agreed rounds, and nothing launches until it works the way your business works.
5
Launch and grow
We deploy, hand over the keys and train you. Then care and growth keeps it secure, fast and improving.
Built with Next.js + React, fast, secure, and built to grow with you. Never page builders.
What you get
Clear from day one. Yours after launch.
No hidden steps, no surprise costs. This is what every project includes, before we talk about extras.
A solution designed around your business, never a template
Design, development, launch and support from one team
A written solution plan and a fixed quote before we start
Phased delivery on bigger builds: pay as value arrives
Live preview during the build, with revision rounds
A modern stack: fast, secure and built to grow
Your data and your code belong to you, full handover
Support after launch, with care plans that keep it healthy

Meet the founder
The person behind the promise.
“I started Zelvvo with a simple belief: every business, no matter how small, deserves digital systems that work as hard as they do. Not a template. Not a placeholder. Software that fits the way you actually run your business, and earns its keep every week.
Zelvvo is founder led. The person you talk to is the person who plans your build, which is why our discovery is honest, even when the honest answer is a smaller project than you asked for.”
Ahmad Qureshi
Founder, Zelvvo
Working with us
Three ways to work with us.
There is no price list for custom work, because no two businesses need the same thing. There are clear ways to engage us, and every one of them starts with a fixed quote.
Fixed-Scope Project
One defined build, one fixed price.
Best when you know exactly what you need
- Written scope before we start
- One fixed price, agreed in writing
- 50% to start, 50% on launch
- Live preview with revision rounds
- Launch, handover and training
Phased Build
Big systems, built in stages.
Best for larger systems and product ideas
- Each phase has its own scope and fixed price
- Every phase is useful on its own
- Continue only when you are happy
- Fund later phases from real results
- This is how our largest systems were built
Care and Growth Partner
A standing tech team for your business.
Best after launch, or for a system you already run
- Maintenance, security and backups handled
- Steady improvements every month
- Priority support when it matters
- Search and conversion work included
- A monthly plan, cancel any time
Not sure which fits? Start with a discovery call. We will tell you honestly which model suits your project, including when the honest answer is to start smaller.
FAQ
Questions, answered.
No. Websites are one of six services. Most of our serious work is custom software: dashboards, stores with accounts and checkout, booking systems and full business systems like ERPs. If your problem needs software, not just pages, that is exactly our work.
