Why counting wood matters
Inventory is everything you hold for production or sale: materials, partly finished work and completed products. Too little can stop a job; too much ties up cash and space. The aim is a useful quantity, not the fullest rack.
For a small shop, start with the items whose absence causes the biggest disruption: your regular sheet goods, matched hardware sets, repeat-product blanks and frequently used consumables.
Give each item a clear identity
Use one item name and one counting unit. Record species or product, grade, thickness, usable dimensions, storage location and quantity. A sheet, board foot and individual board are different units; do not combine them in one total. Keep supplier pack size separate from the unit you issue to jobs.
Label a usable offcut with its actual dimensions and material. A narrow strip is not interchangeable with a full sheet, even when their total area looks promising. Record material condition; pieces awaiting inspection or unsuitable for the intended job are not available stock.
Follow material into and out of the shop
Incoming stock is material ordered but not yet received. Record the order number, expected date and remaining quantity. On delivery, count and inspect it, then transfer only the accepted quantity into usable stock. A late shipment is not material you can cut today.
Reserved stock is usable material promised to an approved job. It remains physically on the shelf until issued, but is unavailable to other work. When it leaves the shelf, reduce both the physical count and that job's reservation; otherwise you subtract it twice. Record returns, damage and usable remnants separately.
Check a little, often
Count a manageable shelf or item group at a time; this is often called cycle counting. For example, check fast-moving hardware weekly and less-used stock on a rotating schedule. Choose a frequency based on how quickly errors could disrupt your shop.
Pause movements during the count or record them carefully. Investigate the difference before adjusting the total: was a pack counted as one piece, a delivery only partly received, or material issued without a job number? This is an operating routine, not a substitute for accounting requirements.
Illustrative shop example
Twenty sheets do not mean twenty are available
In this illustrative count, the physical total includes two damaged sheets and ten sound sheets reserved for an approved job. That leaves eight usable sheets for new work today. Six more are ordered; keep them separate until received and accepted.
| Stock status | Quantity |
|---|---|
| Physically on the rack | 20 sheets |
| Less damaged or held for inspection | 2 sheets |
| Less reserved for approved jobs | 10 sheets |
| Available for new work today | 8 sheets |
| Ordered, not yet received | 6 sheets · not available today |
Try this in your shop
- Choose a consistent name and unit for each item.
- Separate usable, reserved, damaged and incoming quantities.
- Record receiving and job issues when they happen.
- Count one important item group and explain any difference.
- Review shortages before promising a delivery date.
