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 rough brief. One defensible proposal record.

Anvil does not turn uncertainty into polished fiction. It keeps the source, engineering decisions, supplier evidence and export gate attached to the same proposal.

Cold-store monitoring retrofit

“We need to monitor freezer and cold-room conditions. The rooms cannot stop during installation. We need alerts by SMS and email.”

  • Freezer and cold-room duty at −22 °C
  • Installation cannot interrupt room operation
  • Cable route is approximately 60 m
  • SMS and email alerts are required

01 / EXECUTIVE SUMMARY

Cold-store monitoring retrofit

The proposal remains linked to the stated operating environment and delivery constraint. Unresolved alerting is visible before commercial issue.

Scope
Cold-store monitoring retrofit
Delivery
Phased installation, no shutdown
Commercial basis
Evidence and labour review required

The result is not an AI answer. It is a reviewable engineering record that can become a client proposal when the engineer is ready to issue it.

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.

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.

Pricing

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.
