Software we've built for UK and international clients
Why UK businesses come to us
If one of these is your situation, this is how we handle it.
A UK agency quoted a day rate that makes the whole project unaffordable.
Senior engineers at a fraction of a UK agency's rate. Same English-language communication, same professional standards, GMT morning overlap for standups and reviews. Fixed-price, scoped before we start.
Off-the-shelf software fits 80 percent of how you work, and the other 20 percent is spreadsheets.
We build the platform that fits. Bespoke SaaS and operations software modelled on your real workflow. It is what we built for i-mve, now the operations platform 510 UK removals companies run on.
You handle personal or health data and "GDPR-compliant" is currently a hope.
GDPR designed into the architecture. Data minimisation, consent management, right to erasure, audit trails, and UK data residency where it matters, built in from day one rather than retrofitted after an audit.
A previous build was handed over by a team that has since disappeared.
We audit, then take over delivery. A straight assessment of what is salvageable first, then we recover what works and re-engineer what does not. See software project rescue.
Built by AI-native engineers, so AI is a feature ticket, not a rebuild
Every build we deliver for a UK client is architected so language-model features go into your data and workflow when you want them. We design the schema, APIs, and event streams for it from phase one. It is how we built our own products, Tully AI and Mebag.
In-app copilots, drafting, and summarisation wired into the product your team already uses, with humans in control.
RAG over your records, so a plain-language question returns a grounded answer, with data handled to GDPR.
Multi-step workflows wired into your systems, with guardrails, evals, and human approval on anything sensitive.
Shipped with prompt versioning, eval suites, and guardrails. See how we build AI →

Learn moreHow a UK build actually runs
The same track on every engagement. You always know which phase you're in and what unlocks the next one.
Scoping call & proposal
A 30-minute working session in UK morning hours. We map the problem and the outcome, then send a fixed-price proposal with a clear scope and timeline, usually within two working days.
Kickoff & onboarding
A kickoff call with the engineers doing the work. Access and accounts set up in week one, a shared Slack channel, and an agreed weekly rhythm in GMT-overlapping hours.
Design & technical planning
Scope turned into screens, a data model, integration points, and a build order, with GDPR data handling designed in. You review and sign off before code starts in earnest.
Build & weekly review
Development in weekly cycles, twice-weekly written updates, and a working environment you can click through. Scope changes are documented and priced as they happen.
Launch & handover
Production deployment with CI/CD, monitoring, and error tracking. Full Git access, a documentation file, and two months of free bug fixes on what we built.
Iterate or hand off
Most clients move to a monthly retainer for the next features, prioritised against real usage. You can also take the codebase fully in-house, or pause.
Built in Pakistan. Live across the UK.
A product we built from scratch that is now serving 510 UK businesses.
i-mve: all-in-one platform for UK removals and storage
i-mve is a full SaaS platform we built for the UK removals and storage industry. It handles everything a removals company needs to run: job management, automated quoting and invoicing, client contracts, accounting integrations with Xero, QuickBooks, and Sage, and lead generation integrations with Compare My Move, PinLocal, and other UK directories.
Built from scratch by Teamseven. Now live and serving 510 removal companies across the UK, with 314,500+ jobs processed. This is what bespoke software development looks like when it is done properly.

Project rescue and modernizationCommon questions from UK clients
What is the difference between bespoke and custom software?
Nothing, they mean the same thing. "Bespoke software" is the term more commonly used in the UK, while "custom software" is more common in the US. Both refer to software built specifically for your business rather than an off-the-shelf product. We build both.
Are you GDPR compliant?
We build data handling around GDPR principles from day one, not as an afterthought. Data minimisation, consent management, right to erasure, audit trails, and UK-specific requirements are part of our standard delivery for UK clients.
Do you accept GBP payments?
Yes. We can invoice in GBP and accept international bank transfers with no conversion overhead for UK clients. We have been working with UK businesses for over eight years.
How do you handle time zone differences?
Pakistan is GMT+5. That means we have meaningful overlap with UK mornings: we start our day as the UK morning begins. For urgent issues, our team is contactable outside standard hours.
Can you build AI features into our software?
Yes, and we architect for it from the start. Our engineers are AI-native: LLM features, RAG over your own data, and agents that take actions all drop in as a feature ticket rather than a rewrite. When we build AI in, it ships with prompt versioning, eval suites, and guardrails, and data is handled to GDPR. It is the same approach we used for our own products, Tully AI and Mebag.
