# Sheet Goods Inventory: Track Thickness, Finish, and Usable Offcuts Canonical: https://millbase.ca/blog/sheet-goods-inventory-track-thickness-finish-and-usable-offcuts Author: [Coby Birenbaum](https://www.linkedin.com/in/cobybirenbaum/) Published: 2026-10-19 Updated: 2026-10-19 Archive edition: 2026-03-26 Sheet goods become difficult to manage when similar-looking boards share one stock code. Sheet goods become difficult to manage when similar-looking boards share one stock code. Thickness, core, face, finish, dimensions, and grain direction can all affect whether a sheet is suitable for a cabinet job. Make these differences visible before material reaches the saw. ## Define what the team sees - Give materially different specifications separate item identities. - Label locations so full sheets and reusable offcuts cannot be confused. - Record offcut dimensions and finish only when the piece is worth retaining. - Move damaged or uncertain stock into a clearly identified review area. ## An illustrative picking decision A job requires three matching white oak faces. Four sheets on the rack do not establish availability if two belong to a different batch or have a different core. Confirm the job's matching requirements before reserving stock; quantity alone cannot answer that question. ## Keep the system practical Set a minimum reusable offcut rule based on your actual jobs and storage costs. Review retained pieces regularly. A detailed record of unusable scraps is still unusable inventory. ## Distinguish identity, condition, and dimensions Two panels can have similar descriptions while being unsuitable substitutes. Keep thickness, substrate, face and back finish, sheet dimensions, and any relevant batch or matching requirement visible. Record damaged or quarantined material separately from stock that production can issue. For a partial sheet, record actual usable dimensions rather than only its original sheet size. Note defects or cutouts that affect use. A rectangular length-and-width record can overstate the usable area of an irregular piece; the team may need a sketch or a clearly defined minimum rectangle. ## Avoid converting area into a cutting promise An illustrative offcut measuring 600 by 1,200 millimetres has 0.72 square metres of gross area. That does not mean it can provide every group of parts whose combined area totals 0.72 square metres. Part dimensions, kerf, trimming, grain direction, face requirements, and defects determine whether a cutting arrangement is possible. Use the inventory record to find candidate material, then validate the proposed use against the current cutting requirements. Keep the person making that decision clear so a planner does not reserve an offcut that the machinist later rejects. ## Give offcuts a retrieval process An offcut that cannot be found has little practical value. Label it with a stable identifier, store it in a defined location, and remove the record when it is consumed or discarded. Review old pieces periodically using a shop-defined minimum size and realistic reuse demand. The aim is usable material that people can retrieve, rather than an ever-growing list of theoretical savings. ## Related reading - [Inventory Management Software for Woodworking: What to Track First](https://millbase.ca/blog/inventory-management-software-for-woodworking-what-to-track-first) - [Tracking Work in Progress Inventory in a Millwork Shop](https://millbase.ca/blog/tracking-work-in-progress-inventory-in-a-millwork-shop) ## Definitions and further reference - [Oracle: inventory management explained](https://www.oracle.com/scm/inventory-management/what-is-inventory-management/) ## How Millbase can help your shop ### Connect material records to the cabinet job When a component shortage or material change affects a job, start with the recorded stock and the work it supports. [Millbase inventory](https://millbase.ca/#inventory) keeps quantities, material costs, receipts, stock lots, and usage history together. Use [project tracking](https://millbase.ca/#projects) to review the associated labour and material costs, then reconcile the physical material before making a new commitment. Ask the [Millbase AI agent](https://millbase.ca/#how-it-works) a question grounded in your workspace records. For example: *“What inventory records do we have for this material, and what usage is recorded against this project?”* You can select a project or worker, ask follow-up questions, and request [supported reports and CSV exports](https://millbase.ca/#insights). Use the answer to locate the relevant records and investigate the exception. A physical count, approved specification, or supplier confirmation still establishes facts that have not been recorded. ## Explore the wider topic For the broader workflow and decisions behind this guide, read [Warehouse Inventory Management for Project-Based Manufacturing](https://millbase.ca/blog/warehouse-inventory-management-for-project-based-manufacturing). ## Frequently asked questions ### Should an offcut keep its original material identity? Yes, retain the specification and relevant batch identity, then add its remaining dimensions. A generic offcut code can hide finish and thickness differences. ### Can stock be counted only by sheet? Full sheets can use that unit, but partial pieces need an explicit approach. Avoid recording half a sheet when the remaining shape cannot serve the planned parts.
