PlanWise
UK software consultancy

We plan, design and deploy software that works

PlanWise is a software consultancy for organisations that need a product built properly. We scope the problem before we quote, design it with your users, build it with senior engineers and hand it over running in your own cloud.

What we do

Consultancy that covers the whole lifecycle

Engage us for a single phase or the full journey — from the first discovery workshop through to a product running in production with your team supporting it.

Product Discovery & Planning

Turn a rough idea into a costed, prioritised delivery plan — with the risky assumptions tested before you commit budget.

  • Discovery workshops & stakeholder interviews
  • Technical feasibility and architecture options
  • Scoped roadmap with estimates and milestones
Learn more about Product Discovery & Planning

UI/UX Design

Research-led interface design and a component library your developers can build from without guesswork.

Learn more about UI/UX Design

Cloud & DevOps

Infrastructure as code, CI/CD pipelines and monitoring — so deploying to production stops being an event.

How we deliver

From first workshop to live service

Seven stages, one accountable team. Each stage ends with something you can review and a decision that is yours to make — nothing moves forward without your sign-off.

Discover

Typically 2–4 weeks

Workshops with your stakeholders, interviews with the people who will use the product, and a hard look at the systems it has to live alongside.

What you get

  • Problem statement and success measures
  • User journeys and current-process map
  • Risky assumptions, tested
Your decision point You decide whether to proceed — with no obligation to use us for the build.

Plan

Typically 1–2 weeks

Discovery becomes a delivery plan you can budget against: what gets built first, what waits, and what it is likely to cost.

What you get

  • Prioritised backlog and release roadmap
  • Architecture recommendation
  • Costed estimate as a range, assumptions written down
Your decision point Scope, budget range and change process agreed in writing.

Design

Runs a sprint ahead of build

Clickable prototypes tested with real users, then a design system your engineers can build from without guesswork.

What you get

  • Tested prototypes of the core journeys
  • Design system and component library
  • Accessibility checked against WCAG 2.2 AA
Your decision point You approve each journey before it goes into a sprint.

Build

Two-week sprints

Small senior teams shipping working software every fortnight, in your repositories, against a backlog you control.

What you get

  • A demonstrable increment every sprint
  • Peer review and automated tests on every change
  • Documentation written as we go
Your decision point Sprint review with you; reprioritise freely between sprints.

Assure

Continuous, plus pre-release

Quality built into the pipeline rather than discovered by a customer — regression, performance and security checks before anything ships.

What you get

  • End-to-end regression suite on key journeys
  • Load and performance testing
  • Dependency and security scanning
Your decision point Release readiness review against agreed acceptance criteria.

Deploy

Release-ready from the first sprint

Infrastructure as code, automated pipelines and monitoring, in your own cloud accounts — so going live is routine and reversible.

What you get

  • Infrastructure as code in your cloud account
  • CI/CD with automated rollback
  • Monitoring, alerting and runbooks
Your decision point Go-live sign-off and a rehearsed rollback plan.

Support & evolve

Ongoing, or a clean handover

A support agreement with response times in writing and time each month for improvements — or a structured handover to your own team.

What you get

  • Support agreement with defined response times
  • Monthly improvement allocation
  • Handover sessions and pairing, if you take it in-house
Your decision point You own everything — code, infrastructure and documentation.
What we build

Modern software, built to last past launch

From customer-facing platforms to the internal tools that run your operations — including AI where it genuinely earns its place.

SaaS platforms

Multi-tenant products with billing, roles and the admin tooling you need to run them.

Web apps & customer portals

Self-service portals and web applications that take load off your operations team.

Mobile apps

Cross-platform and native iOS and Android apps, sharing an API with your web product.

AI features & automation

Practical AI — document processing, assistants grounded in your own data, and workflow automation — with evaluation and guardrails.

Data platforms & integrations

APIs, integrations with the systems you already run, and reporting you can trust.

Internal tools

Replace the spreadsheets and manual steps holding your team back with software built for the job.

Why PlanWise

A consultancy that behaves like your own team

We work the way a good in-house team works — close to the problem, honest about trade-offs, and accountable for what happens after launch.

Senior-only teams

No layers of juniors billed at senior rates. The people in your kick-off are the people writing your code.

Fixed scope, clear pricing

A costed plan before we start, and a written change process if the scope moves. No open-ended invoices.

Secure by default

GDPR-aware data handling, dependency scanning and secrets management built into the pipeline, not bolted on later.

You own everything

Source code, infrastructure and documentation are yours from day one, in your repositories and your cloud accounts.

Client feedback

What working with us is like

“PlanWise spent three weeks on discovery before quoting, and that changed the whole project. We dropped two features we would have wasted a quarter building and launched earlier than the original plan.”
Operations Director
Logistics platform, UK
“Our releases used to take a full weekend and a rollback plan nobody trusted. Six weeks after they rebuilt the pipeline we were deploying twice a week during office hours.”
Head of Engineering
Financial services
“What stood out was that we owned everything from the start — our repositories, our cloud account, documentation written as they went. Handover was genuinely uneventful.”
Managing Director

Questions

The things clients ask first

How do you price a project?
Discovery is a fixed fee based on the size of the problem. After discovery you get a costed plan with a range rather than a single optimistic number, and we agree in writing how changes to scope are handled. Longer engagements are usually priced per sprint so you can stop at any milestone.
How quickly can you start?
Discovery work can normally begin within two to three weeks of an agreed brief. Full delivery teams typically need three to four weeks of notice, depending on the skills required.
Do we own the code and infrastructure?
Yes, entirely and from day one. We work in your repositories and your cloud accounts wherever possible, and all intellectual property transfers to you under the contract. There is no lock-in to us as a supplier.
Can you work alongside our in-house team?
Frequently. We can supply a complete delivery team, embed specialists into your existing squads, or take a defined workstream while your team handles the rest. We are happy to work in your tooling and ceremonies.
Do you build AI features?
Yes, where they earn their place. We build document processing, assistants grounded in your own data and workflow automation on established model APIs, with evaluation, cost controls and human review designed in. Discovery is where we work out whether AI is the right tool for the problem at all.
What happens after launch?
Most clients move onto a support agreement with defined response and resolution times, plus an agreed allocation of development time each month for improvements. If you would rather run it yourselves, we handle a structured handover including documentation and pairing sessions.
