This is what a credible supplement looks like.
The PDF below is a fully formatted, fictional residential hail & wind supplement — code citations on every line item, tagged photo-callout placeholders, quantity × unit × tax expressed per row, and a defensibility footer at the end. It is the format that makes adjusters stop arguing and start paying.
Documentation, not marketing.
A credible supplement is the document that ends a back-and-forth, not the one that starts one. The three anchors below are the structural choices that turn an ordinary Xactimate export into a reviewer's “approved" rather than a reviewer's “let's discuss.”
1. Code citations on every line
Every scope row cites the governing IRC / IBC section, the manufacturer installation guide, or the applicable Minnesota amendment — the exact authority an adjuster would otherwise have to look up themselves.
2. Photo-callout placeholders
Each line is tagged with the field photo(s) that back the quantity decision, so a reviewer follows the line in the supplement directly to the photo in the set without re-keying evidence.
3. Line-item defensibility
Quantity × unit × sales tax is expressed per row; out-of-scope items are flagged separately; the footer names the statute that governs the materials tax pass-through.
