Custom software for London businesses

Operations platforms, internal systems and SaaS products built around how your business actually works — with roles, permissions, audit history and the integrations that make it one system instead of five.

Why London

London businesses do not have a technology problem. They have a process problem.

London briefs rarely start from nothing. They start from four systems that each hold part of the truth, a process that spans all of them, and a compliance requirement that none of them satisfies alone. The build that works here leaves the systems of record where they are and puts the operational layer, the permissions and the audit history around them.

London is the most competitive buyer of this work anywhere in Europe, which has two consequences. Procurement is sophisticated — expect to be asked about data residency, sub-processors and professional indemnity before anyone looks at your portfolio — and in-house engineering is expensive enough that a bounded external build is often the faster route to a decision. Companies here rarely want a rebuild; they want the gap between four systems closed without disturbing any of them.

Most businesses should buy software rather than build it, and we will tell you when that is the answer. Building is right when the workflow is the advantage, when every product you have trialled needs the process changed in a way your team will not accept, or when the real work is the joins between three systems that no single vendor owns.

What we build

Custom software & SaaS, built to be run by your team.

01

Operations platforms

Intake, ownership, routing, approvals and reporting for the process your business actually runs on.

02

Roles and permissions

What each role may see and do, designed from the process rather than the org chart, and enforced below the interface as well as in it.

03

Audit history

Append-only records of who did what, when, and to what — the thing that turns "the system decided" into something defensible.

04

Integration

CRM, ERP, finance, identity and third-party APIs, with an explicit decision about which system is authoritative for each field.

05

SaaS foundations

Tenant separation, sign-up, billing, support tooling and data export, designed in rather than retrofitted at customer fifty.

06

Hand-over you can act on

Written architecture decisions, a runbook and code your own team can read without the original authors in the room.

Proof you can open

Systems that exist, not case studies that describe them.

We already deliver for UK clients, including the legal practice website at fvollor.com, and we work to UK contract and data protection expectations as a matter of routine.

What good looks like

Four tests any supplier should pass.

If you are comparing suppliers in London, these are worth asking about before the portfolio comes out. They separate a system that will still be working in three years from one that demonstrates well.

See what we commit to ↗

  • A new person can be given the right access on their first morning without a conversation about it.
  • Any record can be traced: who touched it, when, and what changed.
  • The system is deployed, monitored and alerting, and you find out about failures before your customers do.
  • You hold the code, the infrastructure definitions and the data, and could move them tomorrow.

How an engagement runs

Bounded, staged, and reversible at every point.

  1. Map

    We find the real bottleneck, the owners, the data and the decision the system has to make. Usually three to five days.

  2. Prove

    A fixed-scope sprint on the riskiest part, with a success criterion agreed in writing beforehand and the honest answer at the end — including stop.

  3. Build

    Staged releases, each usable on its own, so the business keeps running while it changes.

  4. Hand over

    Written architecture decisions, a runbook, training, and code your team can read. Support is a separate choice, not an assumption.

What it costs

We publish one fixed price — a fixed-scope AI sprint — and we will not quote a workflow we have not seen. The estimator will give you a phased plan, a timeline band and an indicative size against that price, as a document you can forward to whoever signs.

Working with London

Time zones, handled rather than hoped

London runs four hours behind Karachi in winter and five in summer, so a Karachi afternoon is a London morning. Six hours of overlap every working day, 13:00 to 19:00 Karachi against 09:00 to 14:00 London. Stand-ups land at the start of your day and reviews at the end of ours.

What a build here has to satisfy

Rules that shape the architecture

UK GDPR and the Data Protection Act 2018 apply, and the Information Commissioner's Office expects a documented lawful basis, a data processing agreement with every processor, and a record of where personal data goes. For AI features the question that gets asked first is whether personal data leaves the UK or the EEA when a model is called, so that is designed before anything is built.

Before you call

The questions we get asked first.

Should we buy something off the shelf instead?

Often, yes, and we would rather say so in the first conversation than take the project. Buy when the process is standard and your version of it is not a competitive advantage. Build when the workflow is the business.

How do you estimate work you have not seen?

We do not give a firm number before discovery. The scoping estimator on this site will give you an indicative shape and a phased plan in ten questions, sized against our one published fixed price, and it says plainly that it is an indication rather than a quote.

What happens after launch?

Software that is not maintained becomes a liability quickly. Support is a separate, explicit agreement — not a line quietly assumed in the build price — and you are free to take maintenance elsewhere.

Can you work with our existing system rather than replacing it?

Usually that is the better plan. A common and sound pattern is to leave the system of record alone, build the fast-moving operational layer alongside it, and write back only the settled result.

Who actually does the work?

A small named team, with a lead engineer who is hands-on and accountable for the architecture. You will know who they are and talk to them directly.

Next step

Bring the workflow, the product idea or the growth problem. We will tell you what we would build, what we would not, and what it would take — and if the answer is that you should buy something instead, we will say that.
