How this service works
Calculate a draft scope-change quote and delivery-day estimate from bounded effort, rate, costs and capacity. Returns itemized arithmetic and an approval checklist; does not change contracts or send quotes.
Output
Returns an itemized arithmetic breakdown of the scope-change cost (labor, external costs, contingency) and a delivery-day estimate based on available daily capacity, along with an approval checklist. Does not send quotes or modify any contracts — output is read-only and advisory.
Example use cases
Consulting project change order estimate
“I need to draft a scope-change quote for a client — we're adding 600 extra minutes of work at $12000 cents per hour, $50000 in external vendor costs, a 20% contingency buffer, and our team has 360 minutes available per day. Give me the full cost breakdown and how many days it'll add.”
Internal capacity and cost check before approval
“Before I take this to the client for approval, can you estimate the cost impact of adding 1200 minutes of extra work at 9500 cents per hour, $0 external costs, 10% contingency, and 480 available working minutes per day? I just need the arithmetic and the checklist to make sure nothing's missing.”
Fast-track delivery timeline estimate
“How many days would 480 minutes of extra scope take if we have 240 available minutes per day? The rate is 8000 cents per hour, no external costs, and a 5% contingency — I want the itemized quote so I can sanity-check it before sending anything.”
Technical details
Endpoint
POSThttps://instructional-decision-engine-x402.vercel.app/operations/scope-change?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a fast, deterministic arithmetic estimate for a scope change — especially when you want itemized cost components plus a delivery timeline in one call, without triggering any contract modifications or client-facing communications. Prefer this over manual calculation or spreadsheet tools when the output needs to feed an approval workflow or checklist. Not suited for sending quotes or modifying live contracts.
Side effects
- Missing required fields returns a validation error
- availableMinutesPerDay of 0 is rejected (minimum is 1)
- Values exceeding maximum bounds (e.g. externalCostCents > 1,000,000,000) return a 400 error
- Non-integer inputs for integer fields cause schema validation failure
- Contingency percentage above 100 is rejected
