As a development studio, we turn loose ideas, voice notes,
and half-baked diagrams
into structured software specifications your devs can actually build from — no assumptions, no missing logic,
no mid-sprint surprises.
Dev team asks different questions every week.
Flows clarified. Edge cases mapped. Scope cleared.
What’s written doesn’t match what’s expected.
We align technical documentation with logic.
Everyone’s working
off a different version.
Single source of truth established. Specs updated.
No one knows what’s
done until it breaks.
States, roles, behaviors are documented — not improvised.
The more we detail, the fewer surprises in development.
Choose the level of clarity you actually need.

The cost depends on the complexity of the product being specified, the number of functional areas requiring documentation, and whether the engagement includes UX wireframes, data architecture diagrams, and API specifications alongside the written requirements. A focused technical brief for a five-page Seattle professional services website differs significantly from a full product specification for a SaaS platform built for the South Lake Union tech corridor — covering multi-tenant architecture, third-party integrations, billing logic, and role-based access control across multiple user types. We confirm exact pricing after an initial scoping conversation. Most technical requirements engagements start from a few thousand dollars and scale with product complexity and the number of systems involved.
A focused technical requirements document — covering functional requirements, user stories, system architecture overview, and integration specifications — typically takes 2 to 4 weeks for a standard web or mobile project. For Seattle businesses building complex platforms — enterprise SaaS products for aerospace contractors in the Boeing supply chain, healthcare workflow systems for UW Medicine affiliated organizations, or maritime logistics platforms connected to Port of Seattle operations — the requirements phase runs 4 to 8 weeks to cover every functional area, edge case, and integration point with the depth development teams need to estimate and build accurately. We treat the requirements document as a living artifact reviewed and approved in sections rather than delivered as a single monolithic handoff.
Any Seattle business commissioning custom software, a complex web platform, or a mobile application benefits from a professionally written technical specification — but the benefit is highest where the cost of building the wrong thing is significant. In Seattle's tech-dense market, this includes startups in the South Lake Union and Capitol Hill corridors seeking development bids from multiple vendors and needing a specification that enables accurate, comparable estimates, enterprise organizations in aerospace or healthcare commissioning platforms where a vague brief leads to scope disputes mid-project, and growing businesses that have outgrown their current systems and need a precise document to guide a rebuild without interrupting live operations. A professional specification pays for itself in reduced rework costs alone.
A complete technical requirements document covers functional requirements — every feature the system must perform, described from the user's perspective as user stories with acceptance criteria — alongside non-functional requirements covering performance targets, security standards, browser and device support, and accessibility compliance levels. For Seattle clients building products that need to meet HIPAA, CMMC, or Washington state accessibility standards, compliance requirements are documented explicitly as testable criteria rather than general statements. The document also includes system architecture overview, data model diagrams, API integration specifications, user role and permission matrices, and a glossary of domain-specific terms — particularly important for Seattle's aerospace, life sciences, and maritime sectors where technical vocabulary affects requirement precision.
Without a precise specification, development vendors estimate based on assumptions — and different vendors make different assumptions, producing bids that are not comparable and contracts that generate scope disputes when assumptions turn out to be wrong. A technical requirements document gives every vendor the same factual basis for estimation, making bids directly comparable and reducing the risk of a low bid that expands significantly once development begins. For Seattle businesses evaluating multiple vendors in a competitive market — common among startups fundraising in the South Lake Union ecosystem and enterprises running formal procurement processes — a professional specification is the difference between a vendor selection based on actual scope and one based on who made the most optimistic assumptions.
Yes — for projects where interface design is part of the scope, wireframes are included as a component of the requirements document rather than a separate deliverable. Wireframes translate functional requirements into visual representations of user flows and screen layouts, making requirements concrete for both the client and the development team. For Seattle clients in sectors where interface quality is a product differentiator — consumer tech, healthcare patient-facing platforms, and B2B SaaS tools sold to demanding enterprise buyers — wireframes in the requirements phase surface design problems before development begins rather than during it. We document interaction behaviors, empty states, error handling, and responsive breakpoints alongside the wireframes so developers have complete interface specifications rather than layouts that leave behavior undefined.
The requirements process begins with a structured discovery workshop — either in person at your Seattle office or via video call — where we interview key stakeholders from product, engineering, operations, and any other departments whose workflows the system will affect. We then draft requirements sections iteratively, sharing each functional area for review and approval before moving to the next rather than disappearing for weeks and returning with a document your team must review in its entirety. For Seattle organizations with distributed teams across downtown, the University District, Bellevue, and remote locations, all review and approval processes are designed to work asynchronously without requiring everyone in the same meeting.
The completed document serves as the contractual and technical foundation for every subsequent project phase. For Seattle clients who continue with Toimi for design and development, the specification feeds directly into sprint planning and design briefs without a translation step. For clients who take the document to a different vendor or an internal development team, it is written and structured to be self-contained — a developer who has never spoken to us should be able to read it and build the product accurately. We include a requirements handoff session where we walk through the document with your team and your chosen development partner, answer questions, and clarify any ambiguities before the build begins.
