What is Fixed-Fee Engagement?

A delivery model where price is fixed per phase or per milestone — not time-and-materials — so the operator knows the cost before committing to the next stage.

Definition

Fixed-Fee Engagement — explained.

A fixed-fee engagement is the delivery commercial model where the price for each phase or milestone is agreed in advance and committed to in writing, rather than billed by the hour against an open scope. The structure that works in practice for software delivery is: a fixed-fee Discovery phase (typically 2-6 weeks, producing a written scope, technical architecture, and a fixed-fee Build price); a milestone-fixed Build phase (each milestone has a fixed price + acceptance criteria + a working demo); a fixed-fee Pilot at a single site or with a single user group to derisk the rollout; a fixed-fee per-site Rollout; and a recurring Care Plan for the post-go-live operate phase. Change orders are explicit, written, and priced against the same fixed-fee schedule — never absorbed silently into the next milestone. The reasons fixed-fee works for the operator: budget predictability, alignment of incentives (the vendor is incentivised to deliver each milestone efficiently), and a clean exit option at each phase boundary if the engagement isn't going the right way. The reasons it works for the vendor: forcing scope discipline up front prevents the scope-creep that destroys time-and-materials projects. Zeour's default commercial posture across solutions and services is fixed-fee phased engagements with operator self-sufficiency at exit.

Why it matters

Why operators care about fixed-fee engagement.

Time-and-materials engagements have a structural problem: the longer the project runs, the more the vendor earns, which is misaligned with the operator's interest in shipping. Fixed-fee with explicit change orders inverts that incentive without making the engagement adversarial.

What to look for in a vendor

Buyer's checklist

  • Fixed-fee Discovery before Build (price the Build only after Discovery)
  • Milestone-fixed Build with weekly working demos
  • Written change-order process — not absorbed silently
  • Fixed-fee Pilot at one site / user group before rollout
  • Operator owns repo, licenses, and deploy keys at exit (90-day handover)

DT Consultation

digital · transformation · consultation

Zeour Digital Transformation Consultation helps companies digitalise their services and operations through three pillars: process automation (workflow engines, RPA, integration platforms that retire repetitive manual work), self-service technologies (customer + employee portals, kiosks, mobile apps, WhatsApp / SMS / IVR channels), and sovereign on-premises AI (open-weight large language models, vision models, voice models, RAG pipelines, and AI-augmented workflows that run entirely on the operator's own hardware — patient data, customer data, and classified material never leave the perimeter). The service stack is the full path from problem to outcome: consulting (digital-maturity assessment, transformation roadmap, business-case modelling, vendor selection), implementation (the build itself, often delivered in partnership with our Enterprise Development team), AI model deployment (open-weight LLMs, fine-tuning, embedding pipelines, on-prem inference infrastructure, GPU sizing), customisation (tailoring deployed AI and automation to your specific operations — prompts, RAG corpora, workflow templates), and training (role-based curricula for executives, operators, and end users, with operations playbooks, runbooks, and train-the-trainer programmes that make your team self-sufficient). The same team that ships our production AI assistant in MediCare (7-mode OpenAI Responses API, evidence-based prompts, audit-logged interactions) is what you engage.
