Project-Based Outsourcing Services for Product and SaaS Teams
Outsource fixed-scope software with milestone delivery and IP transfer. Discovery, acceptance criteria, and squads for MVPs and migration programs.
We use the Scope Lock Test in discovery to decide whether your next increment needs a fixed-scope project, a dedicated squad, or embedded specialists inside your rituals. Typical stacks include Fixed milestones, written acceptance criteria, shared repo access, IP transfer on completion.

What this service covers
We run defined-scope programs where calendar, budget, and acceptance tests are written before sprint one, not negotiated every Friday.
Discovery and scope definition
Paid discovery when requirements move, written acceptance criteria, and explicit out-of-scope lists.
MVP and integration builds
Two to six engineers for twelve to twenty four weeks with demoable increments every two weeks.
Migration and compliance slices
Framework upgrades, store submission sprints, and audit evidence packs with rollback plans.
Handoff and documentation
Runbooks, architecture decision records, and paired sessions so your team owns day two.
Who this is for
Agencies reselling delivery
You sold a portal or integration and need a partner who signs milestones, not hourly hope.
Founders with a fixed fundraise milestone
Investors expect a demo date and headcount cannot ramp in time.
Enterprises with one-off migrations
A single extraction or compliance sprint does not justify a multi-year dedicated pod.
CTOs converting pilots to production
The spike proved value and now you need fixed acceptance tests before scale-up.
How delivery works
- Discovery (3 to 5 days). Scope, risks, access, and the Scope Lock Test verdict on engagement shape.
- Team assembly (5 to 10 days). You interview engineers before sprint one. Replacements handled if fit is wrong.
- Sprint zero. CI, environments, observability, and definition of done aligned with your team.
- Two-week sprints. Demos, retros with named action owners, and shippable increments.
- Handoff. Runbooks, ADRs, and paired sessions. Optional retainer for audits or seasonal scale.
Team composition
Focused build (2 to 3 engineers)
Tech lead plus two seniors for eight to twelve week MVPs with weekly demos.
Standard project (4 to 6 engineers)
Adds QA automation and part-time DevOps for CI and staging environments.
Complex program (6 engineers plus lead)
Multi-workstream migrations with integration engineer and release manager.
Pricing and engagement models
Project-based engagements typically run USD 15K to 120K for one to six months depending on scope and test depth. Many clients convert to dedicated teams at USD 12K to 60K per month once the roadmap outgrows fixed windows. Staff augmentation at USD 4K to 9K per month per engineer is available when you already own rituals and need individuals mid-project.

Comparison with freelancers, in-house hiring, and staff augmentation
Freelancers fit tiny spikes without accountability. Dedicated teams fit when requirements change weekly for years. Project outsourcing wins when acceptance tests, IP transfer, and a calendar date are the contract.
Example project: Alderwood Product Studio
Composite illustrative scenario based on common Project-Based Outsourcing outsourcing patterns.
Alderwood Product Studio delivered a white-label client portal MVP in fourteen weeks with written acceptance tests, handed repos and runbooks to the agency team, and converted two engineers to staff augmentation for phase two.
- MVP delivered: 2 weeks ahead of agency client deadline
- Acceptance test pass rate at final demo: 100% of signed criteria
- Production defects in first 30 days: 4 to 0 after handoff
- Phase two ramp: 2 embedded engineers in 8 business days

Risks and how we reduce them
Scope creep without change orders
Every new request gets a written impact on date, cost, and tests.
Missing discovery on brownfield
Paid audit week before estimates on legacy repos.
Weak acceptance tests
Criteria are signed by product and engineering before sprint one.
Handoff theater
Runbooks and paired sessions are milestone deliverables, not optional extras.
Frequently Asked Questions
When requirements fit a written scope, a calendar deadline exists, and you want IP transfer at a named milestone.
Yes. Criteria, out-of-scope lists, and demo dates are contract attachments.
Common pattern. Fixed build proves fit, then one to three engineers embed in your rituals.
You do, on completion of the signed milestone, with documented credentials transfer.
Change orders with impact on date and cost. We do not silently absorb scope.
Discovery in three to five days, team assembly in five to ten days, first deliverables week three or four.
