Short answer
A software development subscription is a flat monthly fee for ongoing development work. You add requests to a queue, the team works through them one at a time per track, and you review each piece as it ships. There are no scoping documents, change orders or hourly bills. In the UK, plans typically run from a few thousand pounds a month.
How does a development subscription work?
The model borrows from the design subscriptions that took off a few years ago. Instead of buying a project or a block of hours, you pay a fixed amount each month for continuous output.
- You add requests to a queue. Features, fixes, design changes, integrations, written in plain English.
- The team builds them in order. Each track works on one task until it’s properly done.
- You review and sign off. Feedback goes back into the queue.
- The next request starts. There’s no new quote or contract.
The key mechanic is that each track works on one thing at a time. That’s what makes “unlimited requests” workable: there’s no cap on what you can ask for, and the pace is set by how many tracks you have. More on how that works.
What does “unlimited” mean?
Unlimited requests, not unlimited simultaneous output. You can put fifty things in the queue. They’ll be worked through in the order you set, one per track. If you need more moving at once, you add a track. Any provider that promises unlimited parallel output for a flat fee is either very expensive or cutting corners somewhere.
How much does a development subscription cost in the UK?
Prices vary widely with seniority and what’s included. At the low end, offshore “unlimited dev” services advertise from a few hundred pounds a month. Senior, UK-led subscriptions with product and CTO input cost more. Ours, at current pricing:
| Plan | Price a month (ex VAT) | Tracks | Includes |
|---|---|---|---|
| Embedded | £2,500 | 1 | Unlimited requests, senior review, monthly check-in |
| Embedded Plus | £4,000 | 2 | Plus a half-day CTO and planning session each month, priority on urgent fixes, shared roadmap |
| Partner | From £8,500 | 3+ | Plus a named lead developer, regular CTO strategy time, fastest turnaround |
Very cheap plans are worth a second look. A low price usually means junior people, little review, or a model that works by keeping each client’s output small.
Who is a development subscription for?
It works best for companies that already have a live product and more to build than their developers can get to. Typically 10 to 50 people, with a CTO, technical co-founder or head of product who can prioritise and test. It’s a poor fit if you don’t have a product yet, or if nobody on your side can make decisions quickly.
How is it different from a retainer?
A retainer usually buys a number of hours a month. That made sense when changes took hours. With AI tools, many of them now take minutes, and both sides end up hunting for work to fill the hours. A subscription prices continuous output and judgment instead. Full comparison here.
What should you check before signing up?
- Who reviews the work? Ask whether a senior developer reviews every release, including AI-assisted code.
- Who owns the code? It should live in your repositories and belong to you.
- What’s the term? Ours is 12 months, because product work compounds as a team learns your codebase. Some providers are monthly. Know which you’re signing.
- What happens to urgent bugs? They should jump the queue.
- What’s not included? Hosting, app store fees and licences are usually extra, and better paid by you directly so you own the accounts.
Questions
Is a development subscription cheaper than hiring?
Usually, for the first year at least. A senior hire outside London costs about £88,000 in year one once NI, pension and a recruiter fee are added, and more in London. Embedded Plus costs £48,000 a year at current pricing. Run the numbers.
Can a subscription work on our existing software?
Yes. The codebase gets reviewed early so it’s understood before anything changes.
