The company where the numbers are checked before they ship.
Muntin Digital builds the cost-intelligence tools and the invoice ledger independent restaurants run on. Every number on this site is sourced; the CI gates fail the build on invented data. We compete with the largest vendors on credibility, not headcount.
Muntin Ledger — the invoice ledger.
Snap a photo of a vendor invoice; it lands read, filed, and searchable. Price-hike flags run against your own six-month history. No language model ever reads your documents — a CI gate blocks anyone from adding one.
Pricing is posted in writing at ledger.muntin.digital, with the per-invoice cost math published next to it. Free while in private beta.
The Cost Index — public data, dated and sourced.
Wholesale ingredient prices composed from USDA, BLS, and FRED — published as a dated read with the provenance attached to every point. A thin read gets dropped rather than published.
The free toolset.
Plate costs, margin math, vendor benchmarks, menu copy, site audits — 5 tools that run in your browser, save to your Workshop, and never phone home. Free, no signup, in English and Spanish.
How honesty is enforced here.
Not a slogan — a build step. The repository behind this site runs fact gates on every commit: every number must trace to a source, the banned-vocabulary list blocks marketing-speak, and an invented statistic fails the build before it can publish.
- What we never do — the standing refusals.
- Methods & sources — the voice contract and the fact gate.
- Receipts — public counts, updated from the data itself.
- Data & security — mechanisms, not reassurances.
- AI policy — where models are used and where they are banned.
Founded and run by Don Goldstein.
Full-time Front-of-House Manager at Tacombi in Bethesda; a decade on hospitality floors before that. The product exists because the founder runs the same numbers every week that the tools compute. The full timeline is on the about page.
One next step.
Questions, corrections, or a number that looks wrong — the Window goes straight to Don and every note gets read.
