The technical proposal system for engineering teams

Engineering proposals, controlled from brief to issue.

Turn a rough brief into reviewed requirements, architecture, component evidence, commercial build-up and a defensible DOCX.

One saved record · Seven controlled stages

Take the proposal from intake to issue without losing the decisions behind it.

Three working phases keep the full seven-stage process understandable without hiding the technical and commercial controls inside it.

01 / Define

Turn client language into a controlled engineering basis.

Capture the source brief, resolve scope-changing questions and review eight editable architecture areas before selecting hardware.

Reviewed requirements, confirmed decisions and an editable architecture.

Product walkthrough

See the complete proposal workflow in motion.

Follow one brief through requirements, review, sourcing, commercial build-up and the final proposal. Anvil remains in beta, so the interface will continue to improve.

Inside the walkthrough

  1. 01
    Brief

    Capture source facts and missing decisions

  2. 02
    Architecture

    Review the technical basis before components

  3. 03
    Sourcing

    Keep supplier evidence beside each line

  4. 04
    Commercial

    Apply labour, contingency and terms

  5. 05
    Proposal

    Clear blockers before DOCX export

Safeguards

Anvil shows uncertainty instead of hiding it.

Generated technical work stays separate from commercial evidence. The engineer controls architecture, component approval, assumptions, rates, risks and the final issue.

Read the security approach
01

Verified

Evidence is attached and reviewable.

Accepted supplier results retain the product URL or quote reference, currency, retrieval time and stock information when the source provides it.

02

Engineer required

Uncertainty remains visible.

If a suitable part or price cannot be verified, the line stays unresolved and is excluded from the commercial total.

03

Export blocked

Critical gaps stop the issue.

Deterministic proposal checks and separate export gates must be cleared before the client DOCX can be generated.

The built-in checks support proposal review. They are not engineering certification, legal approval or regulatory compliance.

Before you start

Clear boundaries for engineering work.

Anvil supports judgement and proposal control. It does not replace an engineer or certify a design.

No. Anvil drafts structured work, identifies missing decisions and presents supplier candidates. The engineer reviews the architecture, component matches, assumptions, commercial inputs and final document.
