Why this guide has no price list
Two ai application development projects with the same label can differ several times over in effort. Published price ranges hide that difference and anchor conversations on the wrong question. A useful quote starts from your scope: the capabilities, users, integrations and quality bar your first release needs.
The biggest cost drivers
Data readiness and access
High impactClean, permissioned data is the foundation; preparing it is often the largest task.
Evaluation and quality targets
High impactDefining what good output looks like, and testing for it, drives the delivery plan.
Retrieval or custom model approach
High impactMost applications start with hosted models and retrieval; custom training adds significant work.
Human review and safety
Medium impactReview queues, guardrails and fallbacks protect users when outputs are uncertain.
Workflow integration
Medium impactValue comes from fitting AI into existing tools and processes, not from a standalone demo.
Usage, monitoring and operations
Medium impactModel usage, latency and quality need ongoing monitoring after launch.
How complexity changes the work
Scopeivo classifies projects into four published levels. More complexity means more design, engineering, testing and coordination — not a fixed amount.
Simple
An assistant on a hosted model over a small, well-structured knowledge base.
Moderate
Retrieval over company documents with access control and feedback capture.
Advanced
Workflow automation with tool use, evaluation suites and human review queues.
Enterprise-level
Regulated or high-stakes use with audit, data residency and continuous evaluation.
Team and delivery considerations
Most projects need a product lead, a designer, engineers and quality assurance, though not always full time. Elapsed time also depends on review cycles, content and data readiness, and how quickly decisions are made on your side.
How to get an accurate quote
Partners can only price what they understand. Share these details and ask each partner to state inclusions, exclusions and assumptions.
- The outcome the first release must achieve, and what is out of scope.
- Who will use the product and what each group needs to do.
- Existing systems, data sources and integrations.
- Your preferred launch window and any fixed business dates.
- Who reviews and approves decisions on your side.
- Optionally, a confidential investment range to frame the proposal.
Your brief does most of this for you. The Project Scoper captures each item in about ten minutes.
Scope My AI ApplicationFixed price or time and materials?
A fixed price limits some uncertainty only when scope and acceptance criteria are clear. Time and materials offers flexibility, but needs a spending cap, a reporting cadence and a clear process for changing priorities.
Common mistakes
Comparing a fixed price with a time-and-materials proposal without checking scope; forgetting content and data work; treating a preferred launch date as a validated plan; and leaving accessibility and security until late in the build.
Methodology
This guide is editorial and qualitative. Impact levels describe typical effort, not prices, and Scopeivo does not present estimates as market data. How Scopeivo assesses projects. For an independent process reference, see the GOV.UK discovery guide.
