Why teams switch

ERP-grade inventory valuation, spreadsheet-grade effort

The parts of a full ERP you actually need for inventory value — none of the six-month implementation.

VAL-101

Every item, every location

Value each SKU at each warehouse or store separately, with a location summary and per-item detail table.

SESSIONS

Datasets you control

AS-OF

Point-in-time values

Pick any as-of date and see what your inventory was worth then — quarter-end, year-end, or today.

How it works

From spreadsheet to signed-off in three steps

Upload your transactions

A CSV with date, item_id, quantity, type and either unit or total cost. Location, PO, and memo columns are optional.

Pick a method and date

FIFO, LIFO, or Weighted Average, as of any date. Results calculate automatically for every item and location.

Export and book it

Total value, location summary, and per-item detail — exported to CSV for your close, your taxes, or your auditor.

Valuation methods

FIFO, LIFO, or Weighted Average?

Interactive guides to each method, what it does to your margins and taxes, and which one fits your business. All three run on your data in the workspace.

FIFO

First-In, First-Out

The default — oldest costs leave first

LIFO

Last-In, First-Out

Newest costs leave first (US GAAP)

WAC

Weighted Average

One blended cost per item

AVG

Average Cost

Simple average unit cost
