Only one person understands the system, and they are close to leaving.
Get it documented, then modernised.
We read the code, write down what it actually does, and plan the rebuild around the parts that matter most.
Legacy software modernisation: Replace the old system without stopping the business.
The software is old, the person who wrote it has gone, and everything still depends on it. We rebuild in stages, move your data across and run old and new side by side until your team is happy to switch.
You’re probably here because…
Signs an old system is holding you back.
It doesn’t run on modern browsers, phones or cloud hosting.
Rebuilt on a current stack.
We move it to a modern web stack, usually Angular with Node.js on AWS, or .NET with SQL Server on Azure for Microsoft estates.
You can’t connect it to anything new.
An API around the core.
We add an API so new tools can talk to it, and move functions across one at a time.
A big-bang rewrite sounds too risky.
It is. We do it in stages.
Each stage is quoted separately and runs alongside the old system until your team trusts it.
What modernisation covers
Everything needed to switch safely.
Staged rebuilds
The system rebuilt module by module on a modern stack, with each stage live before the next begins.
Data migration
Years of records cleaned, mapped and moved across, checked with your team before switch-over.
APIs for old systems
A modern API in front of the old code so new tools can connect while the rebuild happens.
Move to the cloud
From an office server or old host to AWS, with backups and monitoring.
Documentation
What the system does, written down, so knowledge no longer lives in one person’s head.
Systems built to replace older software
We say plainly which clients we still work with.

How a modernisation runs
Small, safe steps, each one quoted and signed off.
- Day 1
A 30-minute call
Tell us what the system does, who uses it and what worries you most.
- Next
Read and document
We review the code and data and write down what the system really does.
- Plan
A staged plan with fixed quotes
Which parts move first, what runs in parallel, and the price of each stage.
- Design
Designs you approve
New screens designed and signed off, keeping what your team already knows where it helps.
- Each stage
Build, migrate, run in parallel
Each module goes live alongside the old one, with your data moved and checked.
- Switch
Retire the old system
Once everyone is working in the new system, the old one is switched off and archived.
What modernisation costs
Quoted per stage, so you never commit to the whole thing blind.
A focused first buildFixed quoteA tightly scoped build with one core workflow, quoted after a 30-minute call.
A full projectFixed quoteSeveral user roles, integrations and reporting, scoped in writing before work starts.
Dedicated engineerMonthly rateA full-time engineer working on your product, priced per engineer once we know the stack and seniority.
Included as standard
- A written description of what the old system does
- Data migration and checks with your team
- Parallel running before switch-over
- Git repositories and documentation
- Two months of free bug fixes after each stage goes live
Not included
- Licences for software you keep
- Features added mid-stage, logged as extra hours
After the free two months, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. Book a call and we will price both.
Is modernisation right for you?
We’re a good fit if
- The business depends on the system every day
- You can give us the code and a copy of the data
- Your team can test each stage before it goes live
- You want to own the new code outright
We’re probably not if
- Requests for new features get reported as bugs so they don’t count as scope
- You mainly need graphic design, video or animation
- You want the lowest price above all else, rather than software that lasts

Platform-level reviews of the agency — not cherry-picked project comments.
What I love about Team7 is that they always say: No worries, we can find a solution. This is the mindset of builders, creators, people who do not have fear, the partner you need if you want to excel.
Working with Mo and his team over the past year has been nothing short of exceptional. I was admittedly sceptical about investing such a large amount, but results exceeded every expectation.
Their responsiveness and willingness to take on our challenging task were impressive.
They are amazing and consistently exceed expectations. They go above and beyond what is asked of them and their communication is top notch, so much so that we joke that they never sleep. The best of the best.
Common questions
Straight answers on risk, cost and time.
Ask us something elseDo we have to rebuild everything at once?
No, and we recommend against it. We rebuild in stages, each quoted separately and run alongside the old system until your team is confident.
Will we lose our data?
No. Data migration is part of every stage. We move it, check it with your team and keep the old data archived after switch-over.
What if nobody has the source code?
We can often rebuild from the database and from watching the system in use. It takes longer, and we will say so in the quote.
Who owns the code?
You do. At handover you get the Git repositories and written documentation. There is nothing tying the software back to us, so you can take it to an in-house team whenever you like.
What happens after launch?
Bug fixes are free for two months. After that, monthly maintenance is available. New features are quoted as you need them, or you can add a dedicated engineer. We price both on a call.
Who will I talk to, and how often?
Rehan, one of our two founders, is your day-to-day contact. You get updates on Slack twice a week and can see the code in your repository at any time. We split working hours between us to cover US, UK and Australian time zones, and we usually reply within an hour, sometimes the next morning.
