Addenda
The Addenda home page in a browser window: a light header with the addenda wordmark, Product, How it works, Pricing, Docs and Log in, the serif headline "Every addendum, routed to the right subs.", its subcopy about reading the PDF and drafting the notice, Start trial and See how it works buttons, and the top of a routing diagram beginning below
The Addenda home page hero: the serif headline "Every addendum, routed to the right subs.", "Addenda reads the PDF, finds what changed, works out which trades it touches, and drafts the notice to each subcontractor. You review and send.", Start trial and See how it works buttons, and a diagram below — Addendum 03.pdf, Revised sheets and RFI responses feeding into an Extract Route node, fanning out to Concrete Div 03, Structural Div 05, Roofing Div 07, Mechanical Div 23 and Electrical Div 26

What it does, in one diagram

The How it works section: "From PDF to notified, in four steps." and four numbered cards — 01 Drop in the addendum, 02 Every change, cited, 03 Routed by division, 04 Drafted, never sent — each with its own explanation

Four steps, in order

The Addenda home page on a phone: the addenda wordmark, the serif headline "Every addendum, routed to the right subs.", "Addenda reads the PDF, finds what changed, works out which trades it touches, and drafts the notice to each subcontractor. You review and send.", and Start trial and See how it works buttons

The home page, on a phone

The Addenda pricing page on a phone: "Pricing that does not punish a busy bid week.", its subcopy about paying for bids and people rather than document size, and a Monthly / Annual, two months free toggle

Why estimators use it

The Addenda pricing page in a browser window: "Pricing that does not punish a busy bid week.", its subcopy about paying for bids and people rather than document size, a Monthly / Annual, two months free toggle, and the top of three plan cards — Solo, Team and Firm

Pricing, argued the same way the product is

The three pricing plans: Solo at $49 per month, Team at $149 per month marked Most chosen, and Firm at $399 per month, each listing what it includes, and "14 day trial on every plan. No card to start. Cancel from the billing page." beneath

Three plans, by seats and active bids

The plan comparison table: "What sits behind each plan.", columns Solo, Team and Firm, and rows grouped under Usage — active projects, seats, addenda processed, subcontractor directory — and Extraction — page-cited changes, deadline detection, drawing and spec revisions, confidence flags, manual items and edits — continuing into Routing

What sits behind each plan

The Routing Matrix, using a worked example: "Riverside Civic Center, Addendum 03 · Issued March 11" with a red Bid date changed tag, a table of five changes down the left with their page numbers — p.1, p.4, p.7, p.12, p.9 — and dots across Concrete, Structural, Roofing, Mechanical, Painting and Glazing, and a footer reading "5 changes · 18 subcontractors affected · 0 sent" beside a Review 18 drafts button

A worked example, in the matrix
