Case study

What a structured source-file comparison exposed

A disclosed walk-through of how structured formula, label, and supplier records can expose contradictions.

3 discrepancies surfaced by the comparison. 2 allergen-declaration gaps the printed labels had already carried. 1 serving-count contradiction between supplier documents. Source: an unnamed, founder-controlled, separately incorporated supplement brand that shares a founder with ERRA. Independent customer proof today: zero.

These three numbers come from one disclosed comparison, not an aggregate across customers.

The challenge

The brand is real and shipping. Its formulation data lived where most brands' does: spreadsheets, supplier PDFs, a designer's label files, and email. Nothing looked broken. The labels were printed. The products were on shelves. But the source of truth for a formula, a label, and a supplier's paperwork lived in four separate places that never checked each other.

The comparison

The brand gave ERRA testing access to its formulas. We entered them as structured data, compared the generated Supplement Facts panels line by line with the printed labels, and compared the source data with the supplier documents behind it. Source: an unnamed, founder-controlled, separately incorporated supplement brand that shares a founder with ERRA. Independent customer proof today: zero.

Finding 1: a supplier document named an allergen missing from the working declaration. Finding 2: a second declaration did not match its supplier paperwork. Finding 3: two supplier documents disagreed about serving count. Comparing each source with the structured ingredient and formula record exposed the mismatches before panel generation. Source: an unnamed, founder-controlled, separately incorporated supplement brand that shares a founder with ERRA. Independent customer proof today: zero.

The impact

ERRA derives a Supplement Facts panel from an approved, immutable formula version and records the human decisions that govern release.

One ingredient record carries the allergens, potency, and sourcing facts. The formula references it. The panel, allergen statement, and cost derive from the formula. When the inputs disagree, the system can't quietly render both versions. It forces a decision, and records who made it.
