Pricing
Yii development pricing.
Start with discovery, move to a fixed-price build, or run a dedicated team for a longer roadmap.
Yii discovery sprint
From £2,000
Architecture, roadmap, cost planning, and project-risk validation
- A short strategy sprint covering technical scope, user flows, delivery plan, and budget range.
Managed Yii development project
Fixed quote
MVPs, rebuilds, SaaS platforms, dashboards, portals, and business-critical launches
- Product planning, UX, engineering, QA, deployment, and post-launch support under one delivery owner.
Dedicated Yii development team
From £9,500 per month
Longer roadmaps, multi-sprint delivery, and product teams that need extra senior capacity
- A stable engineering pod with weekly demos, sprint planning, code review, and transparent reporting.
Prices are in GBP. Every estimate is confirmed in writing after a discovery call — the figures above are where engagements start, not a quote.
How we deliver
How we deliver your Yii project.
Seven stages, the same on every project. The length of each one changes with the work; skipping one never saves time for long.
- 01
Product and technical discovery
We map your Yii product goals, users, integrations, compliance needs, timeline, and commercial priorities before planning the build.
Goals, users and constraints agreed
- 02
Architecture and delivery plan
You get a practical Yii roadmap with milestones, team shape, risks, estimates, and the first release path.
Roadmap, team and estimate
- 03
Design, build, and QA
Our team ships the Yii product in controlled sprints with code review, testing, demos, and visible progress every week.
Tested software every sprint
- 04
Launch and improvement
We handle deployment, analytics, monitoring, handover, and post-launch iterations so your Yii platform keeps improving.
Live, monitored and documented
Why Techsleight
What working with us is actually like.
No inflated numbers — just how we run projects, and what you can hold us to.
Product engineering, not ticket-taking
We ask what the software is for before we estimate it — and we will tell you when something should not be built, or should be bought instead.
AI where it earns its place
LLM features, retrieval and automation built with evaluation, guardrails and cost controls, and plain software where that is the better answer.
Full-stack under one roof
Design, frontend, backend, mobile, cloud and QA in one team, so nothing falls between suppliers.
UK-focused delivery
UK business hours, estimates in pounds, and a contract with a UK company. Our engineers are based in the UK and India.
Flexible engagement
A fixed-scope project, dedicated developers or a monthly retainer — and you can move between them as the work changes.
You own everything
Code, IP, cloud accounts and documentation are yours from day one. We sign an NDA before discovery if you need one.
Support after launch
We stay on for fixes, upgrades and new features, or hand over cleanly to your in-house team with the documentation to match.

Questions we get asked.
Straight answers on scope, cost, timelines and how we work. If yours is not here, ask us directly.
What does a Yii development company do?
A Yii development company plans, designs, builds, tests, deploys, and supports Yii software. At Techsleight Labs, that can include discovery, architecture, UI/UX, API integration, QA, cloud deployment, analytics, and post-launch roadmap support.
Do you work with companies in the United Kingdom?
Yes. This Yii development company page is focused on United Kingdom businesses. We support UK collaboration with clear written updates, weekly demos, and planned handoff points so distributed teams can move quickly.
How much does Yii development cost?
Yii development pricing depends on scope, integrations, user roles, design depth, compliance needs, and launch timeline. Discovery sprints start from £2,000, dedicated teams start from £9,500/month, and managed projects are quoted after scope validation.
Can you build a complete Yii product, not just provide developers?
Yes. You can use Techsleight Labs as a full Yii development company for strategy, design, engineering, QA, deployment, and support. You can also start with a small discovery sprint before committing to the full build.
Can you improve an existing Yii application?
Yes. We often join existing Yii products to fix performance, improve architecture, add features, stabilise releases, modernise UI, or prepare the system for scale. We begin with a focused audit so the first sprint is practical.
Who owns the code and product IP?
You own the code, documentation, product IP, design assets, and infrastructure setup created for your project. We can sign an NDA before discovery and work inside your repositories, cloud accounts, and project tools.
How fast can a Yii development project start?
Discovery can usually begin within a few working days of the first call, and most projects start within 5–7 working days of sign-off. Larger builds usually need a short planning sprint to confirm scope, architecture, milestones, risks, and the right team before full development begins.
Do you provide post-launch Yii support?
Yes. After launch, we can continue with monitoring, bug fixes, performance improvements, security updates, roadmap features, analytics, and handover support. Many clients keep a monthly retainer after the main release.
