Problem Solved
Ambiguously drafted SOWs cause scope creep, disputed milestone sign-offs, unpaid vendor invoices, and costly legal arbitration.
When to Use

- •Contracting specialized systems integration deliverables
- •Formalizing inter-subsidiary internal engineering delivery
When NOT to Use
- •For internal agile team sprint backlogs without external vendors
- •For pure staff-augmentation without specific deliverable ownership

Frequently Asked Questions
What is the difference between Fixed-Price and Time & Materials (T&M) SOWs?
Fixed-Price ties payments strictly to verified milestone deliverables with vendor assuming cost variance risk; T&M bills actual hours expended against pre-agreed rate cards with client assuming scope risk.
How should acceptance testing periods be specified?
Define an explicit review window (e.g. 10 business days) upon milestone delivery, with deemed acceptance clauses if no written defects are reported.
