Rescue and upgrade your legacy software with Barsavosh Fanavaran: modernize slow, outdated systems into fast web and mobile apps
Signals

It’s time to rebuild if…

Software nobody likes and that underperforms doesn’t have to be scrapped — it can become a powerful tool.

It is slow

Forms and reports take forever and slow your team down every day.

Few concurrent users

It buckles as more users log in at once and cannot keep up with growth.

Dated, confusing UI

A dated interface makes onboarding hard and human error common.

Weak or abandoned support

The original vendor is unresponsive, updates have stopped, and fixes take months.

Locked to one platform

It only runs on Windows — no web or mobile access for your users.

Your data is at risk

A messy database, no backups and a weak structure put your business data in danger.

Why P-Soft

Why choose P-Soft to rewrite your desktop software for the web?

The right rewrite team keeps your business logic and data intact and delivers a fast, secure web product. That is exactly what we focus on:

  • Desktop-to-web rewrites: we rebuild old Windows and desktop software as a modern, multi-user web application.
  • Your data and workflows preserved: data is migrated from the old system and reconciled, and the way your team works stays familiar.
  • Multi-user, available anywhere: your team works at the same time on the web and on mobile.
  • Phased delivery, no business stop: the old system keeps running while the new one is rolled out step by step, with training and support along the way.
  • Full ownership of code and data: no recurring per-user fees and no lock-in to a single vendor.
FAQ

Frequently asked questions

What is the difference between rewriting, modernizing and repairing software?
These are different names for one goal: turning old, slow or unsupported software into a fast, secure, modern system — whether you call it a rewrite, modernization, revamp or repair. We do all of it, from fixing problem areas to a full core rebuild.
Can you migrate our old Windows software to a web or mobile version?
Yes. Migrating legacy desktop software to a modern web and mobile version — with safe data migration — is one of our most common projects, giving users access from anywhere on any device.
What do I need to send to start?
The flowchart or a description of your current software’s processes, and if possible the software itself or a few screenshots. That is enough to start the review and estimate.
Will my old data be lost?
No. We securely migrate your existing data into the new version’s database so your history is preserved.
How many users will the new software support?
The rebuilt version is designed for dozens of concurrent users — for example, software that previously could not handle more than 10 users supports 50+ concurrent users after the rebuild.
Do you provide support after delivery?
Yes. We take over support, bug-fixing and future updates so you have peace of mind going forward.
Can you rebuild only part of the software?
Yes. Depending on your needs we can rebuild the whole system or only the problematic, slow parts.
Our software vendor no longer supports it and the app is abandoned — what can we do?
If your previous vendor is unresponsive and development has stopped, we take over the support and continued development of that legacy software — and rewrite/modernize it where needed so it becomes reliable again.
Our current app is very slow with a tiring interface — can you make it fast and user-friendly?
Yes. Fixing slowness and redesigning a dated, tiring interface into a fast, modern, user-friendly one is core to what we do — whether the app runs on Windows or the web — resulting in smoother daily work and fewer user errors.
How much does it cost to convert a desktop app to a web application?
The cost depends on the size and complexity of your current software, the number of modules and forms, how much data must be migrated, and any new features. After reviewing your flowchart or existing app we give you a transparent, free cost-and-timeline estimate — and many projects can be delivered in phases to spread the cost.
What is the difference between a real web rewrite and just “wrapping” the desktop app (e.g. Electron)?
Wrapping tools only put your old desktop app inside a shell — it does not become faster, truly multi-user or scalable. We rewrite the software from the ground up with a modern web architecture so it is genuinely fast, secure, multi-user (50+ concurrent users) and future-proof.
How long does a legacy software rewrite take?
Depending on scope it typically ranges from a few weeks for small apps to a few months for larger systems. With phased delivery we hand over the key parts early so your work never stops.
Can you work remotely with businesses in the UAE, Saudi Arabia or Qatar?
Yes. We deliver rewrite and development projects fully remotely for clients across the region and agree on data-hosting and support arrangements (including in-region hosting options) to fit your requirements — at an offshore cost that is typically well below local Gulf rates.
Can Windows software be converted to web automatically?
No. No automated tool can properly convert a desktop application to the web; a real conversion requires re-designing and rewriting the software’s logic on a web architecture so the result is genuinely fast, multi-user and scalable.
What is the difference between a real rewrite and virtualization (remote desktop / VDI)?
Virtualization only displays your old desktop software remotely — it does not become faster, truly multi-user, mobile or scalable, and the slow database stays. We rewrite the software from the ground up on a web architecture so it is genuinely fast, secure, multi-user (50+ concurrent users) and available on mobile.
Our old software is written in Delphi, VB6, FoxPro or Access — can you rewrite it?
Yes. We assess any legacy stack (Delphi, Visual Basic/VB6, FoxPro, Access and more) and rewrite it into a modern web version — even without the original source code — by recovering the business logic from the running app and its database.
Will we have a mobile (Android) version after the conversion?
Yes. The web version works in the mobile browser and, if needed, we also deliver a mobile (Android) app so users can reach the system from any device.
Do you customize the software to our exact needs?
Yes. Software customization is central to what we do — we rewrite and customize the software to match your exact business processes, forms and reports, so nothing you need is missing and nothing you don’t is forced on you.
Should we rewrite our legacy app or just buy a new off-the-shelf product?
If a ready-made product fits your processes exactly, buying it makes sense — but most businesses have built years of unique workflow logic and valuable data into their legacy app that an off-the-shelf product will not cover, forcing you to change how you work. A rewrite keeps that familiar logic and your data while making it fast, secure and web-based — with no recurring per-seat fee and no lock-in to a foreign vendor. In the free review we tell you honestly which option is more cost-effective for you.
Is it better to rewrite, or keep patching our current software?
Endlessly patching an old app gets more expensive and riskier each time: every change breaks something else, the slowness and errors remain, and eventually you hit a dead end as the vendor leaves or the technology is discontinued. If the issues are small and the system is still fixable, gradual modernization is the lower-risk path — but if you keep paying and it is still slow and unstable, a rewrite is cheaper and more stable in the long run. The free review tells you which is right for you.

This service goes by many names: software rewrite, legacy software modernization, re-engineering, system redesign, code refactoring, and legacy migration — all with one goal: turning your slow, outdated system into fast, secure, scalable software. For the full picture, read the software rewrite & modernization guide.
