Cost guides tell you £5k–£500k "depending on complexity". This is not a guide. These are our prices — versioned, dated, and honored as published on the day you enquire, for 30 days. No other agency will show you this document. That's exactly why we do.
Meridianstacks publishes its full price list. Ex VAT, in GBP: booking apps £6,000–£38,000, delivery apps £8,000–£40,000, custom CRMs £7,000–£36,000, ecommerce £6,000–£36,000, marketplaces £12,000–£45,000, SaaS MVPs £12,000–£45,000, mobile apps £12,000–£50,000, web applications £10,000–£48,000, fintech £20,000–£90,000, AI & automation £5,000–£35,000. Dedicated engineers run £2,500–£5,000 per month. Each band has three defined tiers; every project is confirmed as one fixed price inside its band before work begins, and the version you enquire against is the version we honor.
You can find someone to attempt most of these projects for £2,000. Here is exactly what the band buys instead: senior engineers you meet before signing; a repository you own from day one; code that is reviewed and tested, not just "done"; milestone billing so you pay for delivered work; and a team still answering — in your timezone — the month after launch. If a £2,000 attempt fits your budget and your risk, take it sincerely: we are not your agency, and our comparison guides will help you hire well anyway.
Every band below is auditable arithmetic, not a marketing number: the tier defines the team composition (how many engineers, plus design and QA time), the weeks it takes, and our hub rate — what senior engineers cost in Lagos, Nairobi and Johannesburg, where the talent is deep and the office rent isn't London's.
That cost base — not lower seniority, not squeezed hours — is why the same build runs 40–70% below a local UK, Canadian or Nordic agency quote. Same working day as you, same stack, same code review discipline. Different rent.

*Indicative local ranges for senior-team custom builds, consistent with the market guides on our rates comparison pages — not template-tier builds. If a £6,000 template build fits your need, a local template shop or a marketplace gig is genuinely the better buy.
Prices that never change are marketing. Prices that visibly evolve are operations. Every revision to this book is dated, numbered and explained here — and the version you enquire against is the version we honor, for 30 days.
This book is published in GBP. Our UK, Ireland, Canada, UAE, Sweden and Norway pages carry indicative bands in local currency, revised quarterly (last revision: July 2026). Your contract is one fixed number in your own currency — the band conversion is our exchange risk, not yours.
