Board and timber stock counts that never match: causes and fixes

A register counts units. Plywood is not a unit. Saw a sheet into cabinet panels and the offcut goes back on the rack, while the register still shows one whole sheet taken, or nothing taken at all.

Carpenters collect boards early. The store clerk arrives later. A supervisor lends ten sheets to a neighbouring job, someone returns half a sheet to the wrong rack, and nobody writes any of it down.

Month-end arrives and the count differs. Theft gets the blame, or wastage. Mostly it is a recording habit. Walk the shed with the register in hand and pick five lines at random, because the first few mismatches usually reveal the habit behind the rest.

Boards look alike on a stack. Plywood comes in thicknesses, face grades and glue types, and a marine or moisture resistant sheet looks like an interior sheet until someone reads the stamp. Twenty sheets is not a count.

Record each stock line by type, thickness, grade and sheet size, adding the brand whenever the buying rate differs between two makes of the same board. A shortage of one type then cannot hide behind a surplus of another type, which is exactly how most false matches survive a count.

Timber needs a separate view. Count by species, section, length and whether the lot is air dried or kiln dried, using running metres or cubic volume instead of planks.

Every job leaves offcuts. Some are scrap. Some suit a drawer side. If nobody counts them, the book shows a whole sheet gone while the shed holds a half sheet that nobody can locate.

Set a minimum size worth keeping and label each keeper with type, thickness and size before it goes on a marked rack. Log it as a part sheet. A drawer side is the usual cutoff.

Scrap leaves the book too. Log the Friday bin load. That note turns a mystery loss into a known one, and veneered or laminated sheets deserve their own lines, because a scratched face downgrades a board silently.

Issue board only against a job. The slip names the order, the board type, the thickness, the number of sheets and the person collecting, and returns use the same slip, entered as a negative.

At the end of a job, compare what was issued with what the cutting list needed, and the gap is the true waste for that job. Over a dozen jobs, a realistic waste allowance appears for each product, whether it is a wardrobe carcass, a school bench or a kitchen base unit.

Day one needs no software. A printed pad works. Software starts to help when many people issue at once and the totals must be live for the store clerk, the supervisor and the owner.

Count one rack every day instead of the whole shed once a month, and rotate by board type so each line is checked in turn. Small counts are quick. They catch drift early.

Reconcile each count in writing, noting the book figure, the physical figure and the reason for any gap, such as a missed slip or a returned half sheet. Repeated reasons expose habits.

Start with one rule. No slip, no board, for one week. Share the result on Friday with the store clerk and the carpenters, so the people who handle the boards see their own numbers and the gap they create.
