Example workflow estimates

See how much bid admin time you could get back.

Even before estimating begins, contractors spend time opening emails, scanning PDFs, finding due dates, checking site walks, reading addenda, and organizing follow-ups.

These are example workflow estimates, not guaranteed results. Actual time savings depend on bid volume, document complexity, trade, and review process.

Why this matters

A missed deadline can mean a missed revenue opportunity.

A missed addendum can create scope confusion before the bid is even submitted.

A messy inbox can make owners and estimators spend time organizing instead of quoting.

Why this matters

The bid desk gets messy before estimating even starts.

Instead of another row of generic feature cards, Addenda Flow focuses on the operational drag subcontractors already feel: buried invites, scattered documents, addenda changes, and follow-up work that has to happen fast.

Owner view

See what is due, what changed, and what needs a decision.

01Bid invites buried across email threads

02PDFs and plan-room links scattered everywhere

03Site walks and RFI deadlines missed

04Addenda overlooked before review

Save estimator/admin time

Pull basic dates, scope notes, contacts, and follow-ups into one reviewable summary.

Reduce missed deadlines

Bid due dates, site walks, RFIs, and reminders stay visible before they sneak up.

Catch addenda earlier

Flag changes and missing folders so your team knows what needs another look.

Organize the bid pipeline

Give owners and estimators a weekly view of what is open, due, or waiting.

How it works

Forward the invite. Review the summary. Track the bid.

The workflow starts where contractors already work: email. Addenda Flow turns messy intake into a cleaner review queue.

Forward the bid invite

Send bid invites, GC emails, PDFs, and plan-room details to your Addenda Flow inbox.

Get a clean summary

We extract bid due dates, site walks, RFI deadlines, addenda status, scope notes, missing info, and suggested next actions.

Track everything in one bid board

Your team sees what is due, what needs review, what needs supplier quotes, and what needs GC follow-up.

Built for subcontractors first

Starting with low-voltage and security contractors.

Addenda Flow starts with low-voltage and security contractors because your bids move fast, documents change often, and one missed detail can throw off the entire quote. The system is built around real subcontractor workflows, not generic AI chat.

Access control

Cameras

Structured cabling

Network racks

The same bid-intake workflow can expand later into electrical, HVAC, plumbing, fire protection, flooring, drywall, and other subcontractor trades.
