Beyond the packages

Work that gets quoted, not listed

Some builds do not fit a package, and putting a number on them here would be a guess. These are scoped in writing first, then priced against that scope.

Larger builds

Multi-month products, mobile apps, e-commerce platforms and learning systems. Scoped in writing first, then quoted as fixed-price milestones.

Quoted after a scoping call

Describe the project

Agentic and autonomous systems

Agents that carry out real operational work, with tool scoping, approval gates and run tracing. Priced against the process being replaced, not a page count.

Quoted after a scoping call

Describe the project

Ongoing maintenance

Monitoring, dependency and security updates, fixes and a monthly block of improvement hours, once something we built is live.

Monthly, agreed after launch

Describe the project
How buying works

Scope, payment and changes

Four things worth knowing before you order, whether you go through the marketplace or contract directly.

Fixed scope, fixed price

Every package above is a defined deliverable at a defined price. You approve the scope before work starts, and the number does not move unless the scope does.

Starting small

Smaller, well-defined work runs as a single fixed-price package, invoiced on delivery. Most first-time clients start here before committing to a larger build.

Larger engagements

Bigger builds run as a direct contract with milestone invoicing — a deposit to start, then a payment per approved milestone. Same engineering, same process.

Change requests

Scope changes are normal. Anything outside the agreed package is quoted separately, cost and delivery impact in writing, and only built once you approve it.

Honesty first

What we do not do

Turning down the wrong project is cheaper for everyone than discovering the mismatch in week three. Here is where we are the wrong call.

Theme and page-builder edits

Recolouring a WordPress, Wix or Shopify theme is real work, just not ours. We write applications; someone who lives in that platform will be faster and cheaper at it.

Brand identity from scratch

We design interfaces, and we build 3D and motion work on top of an existing identity. Logos, brand books and naming belong with a brand studio, and we are happy to work alongside one.

Game engines and AR

We build cross-platform mobile apps in React Native and WebGL scenes with three.js. Unity, Unreal, AR and anything built around low-level sensor work belongs with a specialist studio.

Paid-ads management

We ship the landing pages, the analytics and the conversion tracking. Running ad accounts month to month is a different discipline and we are not it.

Rescue jobs with no access

We can take over an existing codebase, but not without the repository, the cloud accounts and some way to reconstruct the previous developer's decisions.

Fixed price on undefined scope

If nobody can say what done looks like, a fixed number is a guess dressed up as a commitment. We propose a paid scoping phase instead, then quote against its output.

If your project lands in one of these, say so on the call anyway. We keep a short list of people we trust for the work we do not take, and we will point you at them.

FAQ

Questions we get asked

If yours is not here, email info@northstackhub.com and we will answer it directly.

Book a 30-minute discovery call. We will ask what you are building, what has to be true for it to succeed, and what your budget range is. Within 24 hours you get a written scope summary — free, no obligation, yours to take elsewhere.

Most start small — a fixed-price package with a defined deliverable, so you can see how we work before committing to a build. Larger engagements run as a direct contract with milestone invoicing. The engineering is identical either way.

Fixed price against a fixed scope for defined projects, monthly retainer for ongoing work, and a day rate only for open-ended discovery or audits. You always approve a number before work starts.

It usually does. We quote the change as a separate line item — cost and schedule impact — and you approve it before we build it. Nothing gets added to your invoice that you have not signed off.

You do. We work in your repository and your cloud accounts wherever possible, and everything transfers to you at the end regardless. There is no proprietary framework holding your project hostage.

Every project includes a 30-day warranty covering defects in what we shipped. After that you can take a maintenance retainer, or take the documentation and run it yourself — both are normal and we support both.

We are remote-first and work GMT+5:30, with a daily overlap window for US and European clients. Written updates land every day regardless of overlap, and urgent production issues are covered outside those hours on Priority support.

Yes. We work as an embedded squad inside your Slack and your sprint process, or as a self-contained team reporting to one stakeholder — whichever fits how you already operate.
