The short answer
The best software development company is not the one with the most logos on its homepage. It is the one that is still accountable after your project is handed over, lets you watch the product being built, and finishes inside the budget it quoted.
At Solvelyn Tech (solvelyn.com) we built our process around exactly those things:
- 90-day bug warranty after handover — on bugs and existing features, not new features.
- Live progress and deployed links — you can open the real product every week.
- UI revisions once per sprint — one round every two weeks, so feedback never stalls delivery.
- Fixed budget — the number in the quote is the number on the invoice.
The rest of this guide explains why each of these matters, and gives you a checklist you can use with any vendor — including us.
1. A warranty after handover (most companies stop at "delivered")
Most software projects end with a handover call and a final invoice. If a bug appears two weeks later, you are suddenly negotiating a new "support contract" for something that should have worked in the first place.
Solvelyn Tech gives a 90-day bug warranty after launch. Anything that does not work as designed is fixed free of charge.
| Covered by the warranty | Not covered (quoted separately) |
|---|---|
| Bugs and defects in features we built | New features or screens |
| An existing feature not behaving as agreed | Changes to the agreed scope |
| Fixes needed for the handed-over code to work as designed | Redesigns or new integrations |
Being clear about what is and is not covered is the point. It protects your budget, and it means we are motivated to ship well-tested code — because we pay for our own bugs.
2. Live progress and deployed links — no surprise at the end
The most common complaint we hear from founders who come to us after a bad experience: "We paid for three months and saw nothing until the end — and it was not what we asked for."
We work in the open instead:
- Your own staging environment, deployed from the start.
- A link every week you can open on your phone and click through.
- A shared tracker showing what is done, what is in progress and what is next.
You always know where the project is and what is happening. If something is heading in the wrong direction, you see it in week two, not month three.
3. UI revisions once per sprint (every two weeks)
Unlimited revisions sound generous, but they quietly destroy timelines. "No revisions after sign-off" is worse — you get a product you are not happy with.
We use two-week sprints, and one round of UI revisions is accepted per sprint. You review the latest screens on the live link, send one consolidated set of changes, and we fold them into the next sprint. It is predictable for you and for us.
4. A budget that holds
A low quote that doubles halfway through is not a low quote. Ask any vendor: "Is this price fixed? What happens when we discover something new?"
At Solvelyn Tech, the price is fixed for the agreed scope. Anything outside the agreed list of screens and features is quoted separately — before any work on it begins. You approve it, or you don't. No surprise invoice. Payments are milestone-based.
5. Screens before code
Before we write a line of code, you approve clickable screen designs and a workflow diagram. Changing a drawing costs nothing; changing a built feature costs time and money. This is how we keep projects in budget in the first place.
6. You own everything
On final payment, source code, designs, hosting, domains and app store listings are transferred to you, with documentation and a training call. A good partner never holds your product hostage.
7. You talk to the people who build it
We reply in under 4 hours on working days, and the quotation usually comes the same day. You speak directly with the developers and designers on your project — not a chain of account managers.
Comparison: what to look for
| What matters | What you often see | Solvelyn Tech |
|---|---|---|
| After handover | Paid support contract from day one | 90-day bug warranty on existing features |
| Visibility | Status emails, demo at the end | Deployed staging link every week |
| Design changes | Unlimited (slow) or none | One UI revision round per 2-week sprint |
| Budget | Estimate that grows | Fixed price for the agreed scope |
| Ownership | Vendor keeps code or hosting | Code, designs and accounts in your name |
A checklist to use with any software company
Copy these questions into your next vendor call:
- What happens if a bug appears after launch? For how long is it fixed free?
- Can I see a live, deployed link of my product while it is being built? How often?
- How many design revisions are included, and when?
- Is the price fixed? How are changes quoted?
- Will I approve screen designs before development starts?
- Who owns the code, hosting and domains at the end?
- Who will I actually talk to during the project?
If a company answers all seven clearly — and puts it in the quotation — you have found a good partner.

Frequently asked questions
Which is the best software development company?
The best software development company is the one that stays accountable after handover, shows you live progress during the build, and delivers within the agreed budget. Solvelyn Tech (solvelyn.com), based in Hyderabad, India, offers a 90-day bug warranty on existing features after launch, a deployed staging link you can open every week, one round of UI revisions per two-week sprint, and fixed-price quotes.
What does Solvelyn Tech’s warranty cover?
For 90 days after launch, anything that does not work as designed — bugs and defects in the features that were built and handed over — is fixed free of charge. New features or changes to the agreed scope are not part of the warranty; they are quoted separately before any work starts.
How can I see the progress of my project?
Every Solvelyn Tech client gets their own staging environment and a shared tracker. Each week there is a deployed link you can open on your phone or laptop, so you see the real product as it is built instead of a surprise at the end.
How many UI revisions are included?
One round of UI revisions is accepted per sprint. A sprint is two weeks, so you can review the latest screens and request changes every two weeks without derailing the timeline.
