01
You are buying software for the first or second time
A web app, CRM, e-commerce platform, integration, internal system or AI solution — and you want to get it right.
Independent client-side IT project oversight
Buy software with confidence.
I help companies without an in-house IT team assess vendor proposals, control delivery and accept the finished product — before you approve the final invoice.
If any of these situations sound familiar, you are in the right place
02
You run a business without an in-house IT team
You are an owner, executive or manager making technology decisions that require expertise from outside your company.
03
You have several proposals and cannot choose
Estimates differ substantially, and the proposed scope is difficult to compare point by point.
04
Your project is starting to drift
Deadlines move, scope grows and invoices arrive — but you cannot tell how much of it is justified.
05
Final acceptance and payment are approaching
You want to know the product meets the agreement before you sign it off and approve payment.
Does this sound familiar?
The estimate is hard to assess
A vendor has sent a lengthy, expensive proposal — and you cannot tell whether the price is fair for the actual scope.
See what you can do →No clear finish line
The deadline passed a month ago, and you keep hearing “just two more sprints”.
See what you can do →Business and technology speak different languages
Meetings are full of unfamiliar terms — but you need to make decisions today.
See what you can do →Acceptance without a benchmark
The product is ready for your approval, but you have no reliable way to check whether it includes everything you ordered.

Describe your projectThree phases of one controlled project
The framework I use across engagements, regardless of industry or scale. You can bring me in at any stage.
Scope and documentation
I turn your vision into a clear brief, user stories and backlog. Vendors get the same basis for estimating, and you get a document that protects your interests throughout delivery.
Outcome: vendors price the same scope, proposals become comparable and the risk of hidden costs falls.
Explore the service →Delivery oversight
I represent you within the technical team. I join sprint meetings, verify scope and progress, maintain risk and change logs, and explain technical decisions in business terms.
Outcome: clearer visibility of scope, budget and quality, while maintaining a constructive vendor relationship.
Explore the service →Acceptance and UAT
I run acceptance testing with you and your team. I check contractual compliance, document defects, assess production risks and recommend whether to approve the final invoice.
Outcome: you accept the product on the basis of clear criteria you understand and can justify.

We agree the scope after a free consultation, tailoring the engagement to your project's current stage.
Proposal and estimate review
You have proposals on the table and need to choose.
- Review of proposals from 2–5 software vendors
- Comparison of scope, assumptions and exclusions
- Technical and commercial risk assessment
- A reasoned recommendation
Project brief and backlog
You have an idea but no document a vendor can reliably estimate.
- Requirements and prioritisation workshops
- User stories with acceptance criteria
- Low-fidelity wireframes
- A backlog ready for estimation
Ongoing project oversight
Delivery is under way and you want independent control.
- Participation in planning, reviews and retrospectives
- Scope, change and risk control
- Monthly progress and budget reporting
- Incremental acceptance and vendor discussions
Final acceptance and UAT
The vendor wants sign-off — you need to know whether to pay.
- Acceptance test scenarios
- UAT sessions with your team
- Defect logging and severity classification
- Recommendation: accept, fix or hold

A decade on the delivery side. Now on yours.
For over ten years I have led digital products as a Product Owner, Project Manager and Business Analyst, from startups to large organisations. I now use that experience on your side of the table to protect scope, budget and quality.
I use user stories, BPMN and mind maps to turn business needs into clear specifications. My focus is agile delivery and distributed teams, with constructive, specific communication with vendors.
You do not need to be a technology expert to buy software well. That is where I come in.— Marcin Zaworski, NexusPM

FAQ
Frequently asked questions
What is independent IT project oversight?
It is project management on the client's side, rather than the vendor's. I represent your interests: review scope and proposals, check delivery progress and support acceptance. I do not develop the software — I help ensure the vendor delivers against your agreement and business goals.
When should I involve NexusPM?
Usually before signing a contract (proposal and brief review), at project start (backlog preparation), during delivery (sprint oversight), or before acceptance (UAT). You can bring me in at any stage.
Do you replace the software vendor?
No. I do not write code or compete with development companies. I work constructively with your vendor while asking specific questions. My role is to improve transparency and help ensure the result matches what you commissioned.
Can you help only with final acceptance?
Yes. Final acceptance and UAT can be a standalone engagement. I prepare test scenarios and acceptance criteria, run UAT with you and recommend whether the product is ready for sign-off and payment.
How much does it cost?
It depends on scope: a single proposal review differs from several months of delivery oversight. We agree scope and pricing after a free consultation, once I understand your project and its stage.
Do you work remotely and in English?
Yes. I work remotely across Europe, managing projects and consultations in Polish and English. Documentation is delivered in the client's chosen language.
