What is a development subscription?
A third way to buy engineering, between hiring a team and hiring an agency. Here is how it works and when it fits.
In short
A development subscription is a way of buying software engineering as a flat monthly plan for reserved engineering capacity, instead of paying by the hour or agreeing a fixed price for each project. You send requests continuously and the team works through them in priority order. Plans can usually change each billing period.
Also called: Product engineering subscription, Software development subscription, Unlimited development
Why does a subscription suit a product after launch?
A product is never finished at launch, so a fixed-price project ends just as the real work starts, and hourly billing makes every small change a negotiation. A subscription matches how a live product actually needs engineering: steadily, with priorities that change week to week.
| Agency project | Freelancer | In-house hire | Subscription | |
|---|---|---|---|---|
| How you pay | Per project | Per hour | Salary and overheads | Flat monthly fee |
| After launch | New contract | If available | Yes | Yes, continuously |
| Changing priorities | Change requests | Easy | Easy | Easy |
| If one person leaves | Agency's problem | Work stops | You rehire | Team continues |
How do our Starter and Growth subscription plans work?
Our Starter plan is a flat monthly fee, lower when billed yearly, with reserved capacity, up to two business days to action a request, two production deployments a week and unlimited changes within fair use. Growth is priced around the product. You own the code, data and infrastructure throughout.
Starter costs $2,999 a month paid annually, $3,999 a month billed quarterly, or $4,999 month to month. Current figures are on the plans and pricing page.
How does a subscription differ from hourly and fixed-price contracts?
It moves the risk to a different place. US federal contracting rules describe the two older models clearly. A time-and-materials contract pays fixed hourly rates and suits work whose scope cannot be estimated. A firm-fixed-price contract sets one price and puts the cost risk on the supplier. A subscription fixes the fee and lets scope move.
- Time and materials: FAR 16.601 says it gives the supplier no positive profit incentive for cost control or labor efficiency, so the buyer must watch performance and set a ceiling price.
- Firm fixed price: FAR 16.202-1 says the supplier carries maximum risk and full responsibility for costs, which works when the scope is defined in advance.
- Subscription: the fee buys capacity for a period. The buyer chooses what that capacity works on, and can change the order each week.
For a live product, the scope is rarely known in advance, which is why a fixed price fits launch projects better than the months after. The subscription vs agency comparison sets the options side by side.
What mistakes do buyers make with a development subscription?
Most mistakes come from reading the word unlimited too literally, or from not checking who owns the work. In our view, the questions to ask any provider are about capacity, turnaround, ownership and what happens on cancellation, because those decide whether the plan suits your product, more than the monthly price does.
- Treating unlimited requests as unlimited output. Requests queue against reserved capacity, so the order you set matters.
- Leaving repositories and hosting in the provider's name, which turns a supplier into vendor lock-in.
- Sending vague requests. A short statement of the problem and the expected result saves a round of questions.
- Using a subscription when what you need is extra hands managed by your own lead. That is staff augmentation.
Common questions
What is not included in a development subscription?
It varies by provider. Typically infrastructure and third-party services are billed separately; ours are billed to you directly, at cost. What the fee covers is reserved engineering capacity: requests are sent continuously and the team works through them in priority order.
What happens if I cancel?
With us, you keep everything: repositories, infrastructure and documentation. You own the code, data and infrastructure throughout the subscription, not only when it ends. Infrastructure and third-party services are billed to you directly, at cost, so nothing has to be transferred back.
How is a development subscription different from hiring a freelancer?
A freelancer is usually paid by the hour, and the work stops when that one person is unavailable. A subscription is a flat fee for a team's reserved capacity, so work continues if one engineer leaves. Which suits you depends on how steady your engineering need is.
Is unlimited development really unlimited?
Unlimited usually means unlimited requests, not unlimited output. The fee buys a fixed amount of engineering capacity, and requests are worked through in priority order within it. Check each provider's fair-use terms, turnaround time and number of production releases before assuming what unlimited covers.
