Film tracked to the foot

Definition

Why track film to the foot instead of by the roll?

  • Film tracked to the foot — Inventory that counts film by the linear foot remaining on each roll, at the real cost you paid, with lot numbers and reorder points — instead of treating a four-figure roll as a single line item.
  • It's what makes true material COGS and reorder alerts possible.

Why it matters to a shop

A four-figure roll treated as one inventory line cannot tell you what a job consumed. Tracking to the foot is the mechanism that makes live margin, real per-job COGS and a reorder alert that fires in time all possible at once. The method, step by step, is how to track film inventory.

FAQ

Film tracked to the foot questions, answered

Why track film by the linear foot instead of by the roll?

Because a job consumes feet, not rolls. A four-figure roll held as one inventory line can tell you it exists and nothing else: not what this job used, not what is left, not when to reorder, not what the job actually cost. Tracking feet is the mechanism that makes true per-job material cost and a reorder alert that fires in time possible at all.

Does tracking to the foot mean measuring every cut?

It means recording what came off which roll on the job, which is a line on the work item rather than a separate stocktake. The measuring is already happening at the cutting table; what changes is that the number lands on the record instead of in somebody's head, and the roll's remaining feet update themselves.

What does foot-level tracking change at month end?

Cost of goods sold stops being an estimate. Each finished job carries the film it consumed at the price that film was bought for, so revenue minus cost is a real number rather than a plug. That is also what makes the busiest month comparable to the most profitable one, which is usually the more interesting comparison.
