Your customer approves a quote, then sends a revised specification with “just a few minor changes”. A different finish, extra assembly step or tighter tolerance can change the work involved without changing the agreed price. When those details reach production before your estimator sees them, your business can absorb costs it never agreed to cover.
We build an AI specification tracker in n8n that compares incoming customer documents against the version used for your quote. It identifies changes in readable text and tables, links each finding to its source and prepares a review for your estimator. Your team decides which changes need clarification, a revised price or written approval before work continues.
What You Get:
- A monitored shared mailbox and document folder for incoming customer revisions.
- A baseline record that connects each job to its quoted specification, accepted proposal and stated exclusions.
- AI extraction and comparison of quantities, materials, finishes, dimensions, tolerances, packaging requirements and delivery dates from agreed document formats.
- A change register that shows the original requirement, revised requirement and source reference together.
- A review queue that separates clear differences from ambiguous wording and missing information.
- Draft customer clarification messages and variation summaries for your team to approve.
- An approval record that links each accepted variation to the relevant document version.
- Configuration for one business unit and up to three recurring specification templates, historical testing and a documented handover.
The Benefits to You:
- Your estimators can review specific changes without rereading every document from the beginning.
- Your production team can see which revisions have commercial approval and which remain unresolved.
- Your account managers have evidence to explain why a minor change may affect the price.
- Your business keeps a clear record of what the customer requested and what your team accepted.
- Your staff retain control over pricing, customer messages and production decisions.
The setup covers readable text and tables in agreed file formats. It does not interpret CAD geometry or certify engineering requirements. Software subscriptions and ongoing support are quoted separately.
Send a sample quote, its original specification and a later revision so that we can confirm what the system should compare before your build begins.
