Most outsourcing engagements fail for the same reason: the client did not know how to evaluate the partner before signing, and the partner did not understand the product well enough to ask the right questions. If you are a founder in Bosnia and Herzegovina or the wider region and you are weighing an external team, your first step is one page of text: what the product does, who uses it and what "done" means for version one. Without that page you can neither compare quotes nor verify delivery.
This guide goes in order: when outsourcing makes sense, how to vet a partner, what the contract and technical setup must cover, and how to run the project once it starts. For comparing options, see agency vs freelancer for a SaaS MVP, in-house vs outsourcing and the overview of outsourcing companies. Cost ranges are covered in what it costs to outsource SaaS development, so I deliberately do not repeat prices here.
When does outsourcing SaaS development make sense, and when does it not?
Outsourcing makes sense when you have a clearly defined scope, cannot hire fast enough and can judge the quality of what is delivered; without those three conditions the risk outweighs the benefit.
Outsourcing SaaS development means an external team (an agency, a solo developer or a firm in another country) delivers an agreed result: a product, specific features or maintenance. It is not hiring. The external team has its own processes, tools and other clients, so you manage it differently from an internal team.
What are the signs that outsourcing is the right choice?
Outsource when:
- you are a non-technical founder and need a first version to test the idea
- you have a defined scope and want to start faster than you can hire
- you need a narrow skill (mobile development, for example) that does not justify a permanent hire
- your internal team is at capacity and you need parallel work
Do not outsource when:
- you cannot clearly describe what you are building
- nobody on your side can judge code quality (a technical co-founder, advisor or CTO)
- the product itself is your only competitive advantage and you cannot protect it with a contract and access control
What does the data say about ICT specialists in the region?
Eurostat reports that in 2025 more than 10 million people worked as ICT specialists in the EU, which is 5.0% of total employment (Eurostat, ICT specialists in employment, 2025). The same source notes that in Bosnia and Herzegovina, Türkiye and North Macedonia the younger age group makes up the majority of ICT specialists, 53.7% in Bosnia and Herzegovina.
That figure says nothing about the quality of any single team, and you should not use it as a selection criterion. My conclusion is practical: the partners available in the region include both young teams and experienced individuals, so check delivered work rather than years of experience.
How do the outsourcing options differ?
| Option | Where it is strongest | What to watch |
|---|---|---|
| Agency | Wider team, established processes, replaceable people | A management layer between you and the developers |
| Solo developer | Direct communication, flexibility | One person is one point of failure |
| In-house team | Full control and product knowledge | Hiring time and fixed costs |
A deeper comparison of these models is in solo developer vs agency vs in-house.
How do you vet an outsourcing partner before signing?
Check technical depth in your stack, how the partner handles an unclear requirement, the communication format and references you actually call, rather than portfolio aesthetics, company size or hourly rate.
What should you ask a partner for?
Technical depth in your stack. If you are building on Next.js + Supabase, ask which projects they have shipped on that stack and ask to see the code. A good partner will not object.
Handling of ambiguity. Give them an incomplete requirement and watch the questions they ask. Good partners ask about the user's goal, bad ones ask about button size in pixels.
Communication format. "Every Friday we send a short video demo and a written list of blockers" is an answer. "We stay in touch" is not.
References. Ask for a reference from a client whose product is similar to yours in scope, then actually call them. A question worth asking: "What did they get wrong and how did they fix it?"
What are the red flags?
- a fixed-price quote arrives before detailed questions about your product
- the partner cannot explain how they would approach your architecture
- earlier clients do not want to be references
- the partner refuses code review or a code ownership clause
A complete vetting checklist for agencies is in how to vet a SaaS development agency.
What must the contract and technical setup cover?
The contract must transfer code ownership to you on payment, give you administrator access to the repository from day one, define measurable deliverables and regulate the processing of personal data.
How do you secure ownership of the code?
Code, designs and other materials must be assigned to you, not licensed. Open the repository in your own organization and add the partner as a member with limited roles. GitHub's documentation states that organization owners have complete administrative access and that there should be no fewer than two of them (GitHub Docs, Roles in an organization). The recommendation is mine: be one of those owners from day one, not at the end of the project.
An example documented in a case study: for Pizzeria Bestek (React + Supabase, single location) a fixed price was agreed with a full handover, so the restaurant owns the codebase, the Supabase account, the Netlify deployment and the Resend account.
How do you define deliverables and payment?
"The login is done" is not a deliverable. "A user can register with email, log in, reset a password and open their dashboard" is. Tie payments to deliverables, not to time. A split of 30% on signing, 40% on staging delivery and 30% after production release and acceptance is only an example of a structure, not a standard, so adapt it to the risk of your project. The same goes for termination: ask for the ability to exit on short notice and keep everything completed so far.
What should the contract say about personal data?
If you serve users in the EU, a partner who works with their data has the role of a processor. Article 28 of the GDPR requires that processing be governed by a contract, that the processor acts only on instructions, that sub-processors need written authorisation and that data is deleted or returned at the end (GDPR, Article 28). A contract that does not cover this is incomplete.
The technical side is just as important. Do not give the partner production database access. Supabase's documentation states that each branch is a separate environment with its own instance and credentials, and that new branches do not start with data from the main project by default (Supabase Docs, Branching). That is a good basis for a staging environment with synthetic data. Keep secrets in a secrets manager or environment variables, never in code or in a message.
What should an engagement deliver besides code?
- Architecture: database schema, API design, authentication pattern and multi-tenancy approach, before the first line of code
- UI/UX design: wireframes, a design system and responsive layouts, or clear mockups from you
- Development: frontend and backend
- Testing: automated tests for authentication, billing and core flows, manual QA for the rest
- Deployment: CI/CD, staging and production, error monitoring
- Handover documentation: how to run the project locally, how to deploy it, where credentials are and how the data model works
Without the last item you stay dependent on the partner. My engagements are project-based, not hourly: scope and timeline are agreed upfront (6 to 12 weeks for a SaaS MVP) and the price is given on request.
How do you run an outsourced project without losing control?
Stay available: ask for a short written update every day and a weekly demo of the working build, and review every major pull request yourself or through a technical advisor.
What communication rhythm works?
- Daily update: a five-minute message covering what was done, what is next and what is blocked.
- Weekly demo: 30 minutes of video with the working build, and you give feedback right then, not two days later in a document.
- Retrospective every second week: what works, what does not, what changes.
- Code review: every major pull request is reviewed by someone who understands the code.
For tracking delivery, DORA defines five metrics: change lead time, deployment frequency, failed deployment recovery time, change fail rate and deployment rework rate (DORA, software delivery metrics). A small team can start with two: how often you ship and how often a release needs an urgent fix.
How do you avoid the most common problems?
Scope creep: every change outside the specification costs time and money. Keep a change log and agree changes in writing before implementation.
Communication gaps: choose written communication for anything related to decisions. A short video with an explanation leaves a trail, a call does not.
Quality drift: without code review, quality declines over time. Review code at every milestone and deal with technical debt before it grows.
Vendor dependence: if only the partner can deploy or understand the code, you have a problem. Ask for standard tools, documented architecture and automated deployment from the start.
Which tools make up a standard setup?
| Category | Example tool |
|---|---|
| Version control | GitHub |
| Tasks | Linear or Jira |
| Communication | Slack |
| Async demos | Loom |
| CI/CD | GitHub Actions |
| Monitoring | Sentry + UptimeRobot |
| Deployment | Vercel (frontend), Supabase (backend) |
This is one reasonable set, not the only one. What matters is that you control the tools, because a partner with proprietary tooling builds dependence.
What does a well-run engagement look like?
A hypothetical example, not a real client: a non-technical founder hires a two-person team for an MVP. They agree weekly demos, milestone payments and a review of every major feature on staging before production. If the partner reports midway that the multi-tenancy architecture will not handle the planned growth without a schema migration, that is a good sign: the problem was found while the fix was cheap, not after launch.
Your next step: write a one-page scope description with three acceptance criteria, send it to two candidates and compare which questions they ask before they quote a price. If you want to go through it together for your product, write to me.
