The verdict in three sentences
A rigorous requirements spec costs 12,000 to 26,000 EUR but cuts quote variance between vendors threefold and de-risks a 50,000-110,000 EUR build. Without a spec, quote variance hits 20 to 35% and scope creep explodes mid-project. For a Berlin legal director, the spec is the project's cheapest insurance.
The lines of a business software scoping phase
Scoping turns a vague need into costable specifications. Each deliverable reduces risk and sharpens the quote. 2026 orders of magnitude for legal business software in Berlin.
| Deliverable | 2026 price | Lead time |
|---|---|---|
| Scoping workshop | 3,500-8,000 EUR | 1-2 weeks |
| Functional spec (4-8 days at 600 EUR/day) | 2,400-4,800 EUR | 1-2 weeks |
| Prototyping / mock-up | 5,000-10,000 EUR | 1-2 weeks |
| Associated build estimate | 50,000-110,000 EUR | — |
| Total scoping | 12,000-26,000 EUR | 3-5 weeks |
Prototyping is often underrated: seeing the interface before development avoids weeks of rework. It is the deliverable that aligns legal, IT and the vendor.
Fixed price on spec vs agile time-and-materials
| Criterion | Fixed price on spec | Agile T&M |
|---|---|---|
| Prerequisite | detailed spec essential | product vision is enough |
| Budget control | firm price | rolling budget |
| Scope flexibility | low (change orders) | high |
| Quote variance without scoping | 20-35% | not applicable |
| Ideal for | stable scope | evolving product |
| Indicative day rate | 600-750 EUR | 550-700 EUR |
Fixed price demands a solid spec, otherwise change orders pile up. T&M suits an evolving product, provided an internal product owner is available.
Mini case study
Mr. Vogel, legal director of a group in Berlin, is considering business software at 90,000 EUR. Tempted to skip scoping, he consults three vendors without a spec: quotes range from 78,000 to 115,000 EUR, a variance of 37,000 EUR (32%). He finally invests 18,000 EUR in a workshop, a functional spec and a prototype. The result: new quotes land between 88,000 and 96,000 EUR (9% variance), and the project starts without grey areas. The 18,000 EUR of scoping saves him an estimated 25,000-35,000 EUR of mid-project drift: the spec pays for itself before the first line of code.

Why pay for a requirements spec before the quote?
Because without one, quotes vary by 20 to 35% and scope creep accumulates. A spec at 12,000-26,000 EUR de-risks a 50,000-110,000 EUR build.
What does the scoping workshop cost?
Between 3,500 and 8,000 EUR depending on the number of stakeholders and business complexity. It is the starting point of any serious project.
Is prototyping really useful?
Yes: 5,000 to 10,000 EUR to see the interface before development avoids weeks of rework and aligns all stakeholders.
Fixed price or agile T&M?
Fixed price on spec for a stable scope and firm price; agile T&M for an evolving product with an available internal product owner.
How long for scoping?
From 3 to 5 weeks for the full workshop + spec + prototype, before consulting vendors on a solid basis.
