The problem

A busy show should not end in a pile of notes and a guessed profit number.

Spreadsheets can hold inventory. Notes can remember a few deals. Neither is built to follow a card from the case, through a bundle or trade, into the final show result. Jerbventory connects those steps without requiring a connection at the table.

One Show · Five connected stages

Follow one ledger from Draft to a closeout you can trust.

Jerbventory is organized around the full day behind the table. Every stage adds evidence to the same Show, so the final result never has to be reconstructed from scattered tools.

Show Mode · Available in beta

The ledger that stays with the table.

Show Mode keeps the active event, its exact Inventory, quick actions, pending work, and past activity in one focused workspace.

See what this stage records
  • Sell at the stored Show ask or enter a guarded custom price.
  • Record sales, bundles, trades, purchases, fees, and event expenses.
  • Attribute cash, digital payments, and processing fees correctly.
  • Undo safely with audited, idempotent reversal safeguards.
  • Keep Draft and Needs Review work out of finalized results.

Snap Deal · Needs Review

When the table gets busy, save the moment—not a bad guess.

Create a Quick Capture as a sale, purchase, trade, or unknown activity. Add a private on-device photo as a memory aid, then resolve the details when traffic slows down.

See what this stage records
  • Preserve rushed activity without forcing incomplete details.
  • Exclude unresolved work from finalized results.
  • Confirm the cards, money, and payment method later.
A memory aid, not a scanner. Jerbventory strips image metadata and does not upload, recognize, price, or match the photo.

04Reconcile

Reconcile

Resolve the exceptions, not the whole Show.

Compare expected and physical quantities, then focus only on the differences that need attention before closeout.

See what this stage records
  • Use recorded activity to calculate what should remain.
  • Check physical Inventory against the Show Ledger.
  • Keep unresolved differences visible until they are handled.

05Close out

Confidence Closeout

Close the Show with evidence, not optimism.

Jerbventory blocks completion while unresolved activity remains, separates payment methods, shows where cost basis is missing, and records an immutable result when the Show is closed.

See what this stage records
  • See gross sales, fees, expenses, and realized card profit.
  • Review cost coverage, payment methods, and cash movement.
  • Preserve remaining Inventory in a trustworthy read-only result.
A later audited reversal can restore Inventory without silently rewriting the historical closeout.

Reusable Shows

Your next show should not start from zero.

Reuse a completed or cancelled Show once, or save a durable template for a recurring event. A new independent Draft uses current Inventory quantities and asking prices while the source Show’s sales, expenses, closeout, and history stay untouched.

Jerbventory explains anything copied, capped, or skipped.

Inventory + Collection

Two vaults. One hard boundary.

Jerbventory keeps what you sell operational and what you keep personal—without letting either side quietly distort the other.

OWNERSHIP ROUTING

Every card has a deliberate side.

01FOR SALE

Inventory

What you actively sell and account for.

  • Acquisition lots
  • Quantity + locations
  • Unit cost
  • Asking price
  • Stored market value
  • Pricing coverage

Can be allocated to an exact Show manifest.

HARD
BOUNDARYNO ACCIDENTAL
CROSSOVER
02KEEPING

Collection

What you own without intending to vend.

  • Owned cards
  • Personal sets
  • Browse + organize
  • Separate value context

Never enters vending totals, manifests, or realized profit.

ONE WORKSPACEClear intent in. Trustworthy numbers out.TWO LEDGERS

Workflows support Pokémon, Digimon, Magic: The Gathering, One Piece, Basketball, Baseball, Football, and Soccer. Catalog and automated-pricing availability varies by category and release. Only Pokémon and Digimon currently have automated price-provider workflows; other categories keep manual or imported values explicit. Jerbventory never invents a price.

CSV + XLSX Import

Start with the records you already have.

Import structured CSV or multi-sheet XLSX files into Inventory, Collection, or both. Jerbventory recognizes common columns, previews every change, validates rows, identifies duplicates, protects against importing the same file twice, and produces a rejected-row report that can be corrected and re-imported.

Nothing is written until you confirm the preview.

Local-first trust

Designed to keep working when the venue Wi-Fi does not.

Core holdings and Show workflows live on the device. Backups use a verified, versioned archive; restore validates the archive before changing the workspace.

01

On-device core

Your Inventory and Show Ledger remain available locally at the table.

02

Verified backup

Archives are versioned and validated before restore changes your workspace.

03

Platform-aware

Android rotates verified backups in a selected folder. iOS supports checkpoints and explicit export to Files or a cloud-backed location.

Local-first does not mean loss-proof.Verified archives should be exported and stored separately from the phone.

Product roadmap

The first release is the foundation—not the finish line.

Jerbventory can grow from a trusted solo-vendor Show Ledger into a much deeper operating system for the card community. The pipeline is broad, but every step must protect exact Inventory, money, and audit history. No invented delivery dates.

CORE PRODUCT FOUNDATIONThe workflow being built first
  • Show lifecycle + exact manifests
  • Sales, bundles, trades, purchases + expenses
  • Needs Review, reconciliation + immutable closeout
  • Import, local-first backup + reusable Shows

Honest boundaries

What Jerbventory is not.

A payment terminal
A card marketplace
A formal tax system
An AI card grader
A scanner-first app
A storefront or shop POS

Jerbventory does not process payments, list cards for sale, provide formal tax accounting, grade cards with AI, or guarantee the accuracy of information a user enters. It is currently single-user and local-first, without cloud sync, team accounts, or storefront tools.

Coming soon

A better Show day is being built.

Jerbventory is being shaped around the complete workflow of the individual vendor—from the first card packed to the final reconciled result.
