# 3.2 · Choose an Inventory Lane

> Choose a primary inventory lane from your cash, time, knowledge, and downside constraints, then set allocation and review rules.

Two businesses can have the same amount available for inventory and still need different
lanes. One owner may have ten reliable hours each week but need cash back quickly. Another may
have little spare time, strong product knowledge, and capital that can remain committed for
longer. Available cash alone does not decide.

[Chapter 3.1](/chapters/3-1-the-four-product-classes) compared how singles, sealed products, bulk, and slabs consume cash, labor, and
judgment. Your task now is to eliminate the lanes that break a real constraint, then give one
of the remaining lanes a clear job.

## Start with limits you cannot negotiate

Write the limit before thinking about what you would most enjoy buying. Use amounts and dates
you can defend, not labels such as *low risk* or *plenty of time*.

| Constraint                      | Write your limit                                                              | What it may rule out                                                     | Evidence still needed                            |
| ------------------------------- | ----------------------------------------------------------------------------- | ------------------------------------------------------------------------ | ------------------------------------------------ |
| Provisional inventory pool      | \$\_\_\_ already isolated for inventory during this review period             | A lane whose total planned allocation would consume too much of the pool | Actual lot sizes and complete offer math         |
| Required cash-conversion window | Cash should normally return within \_\_\_ days                                | Inventory whose realistic sale cycle is longer                           | Completed sales, demand depth, and payout timing |
| Weekly labor                    | \_\_\_ dependable hours for intake, listing, storage, and fulfillment         | A lane whose recurring work exceeds those hours                          | A timed sample batch                             |
| Knowledge boundary              | I can reliably identify and evaluate \_\_\_                                   | Inventory whose version, condition, or demand I cannot yet defend        | Error log or expert check on a small sample      |
| Tolerable lane loss             | At the planned review or exit point, this lane may lose no more than \$\_\_\_ | A lane whose conservative exit case exceeds that amount                  | Exit price, selling costs, and units exposed     |

For now, use only cash you have already isolated for inventory. If the full capital policy is
not written, label this pool provisional and choose it conservatively rather than reading the
number from a bank balance. [Chapter 5.2](/chapters/5-2-bankroll-discipline) defines the complete capital boundary later; revisit
the thesis after finishing it.

The limits need not be permanent. They describe the operation you can support now.

## Eliminate before you choose

Return to the product-class comparison and test each class against the five rows. Cross out a
lane as soon as it violates a hard limit. Do not rescue it with an optimistic sale price, an
unusually quiet week, or the hope that you will learn the product after committing most of
the cash.

Elimination also exposes missing evidence. A lane may appear to fit the capital limit but fail
the labor test once you time a real batch. It may fit the schedule but fail the knowledge test
when condition calls or variants produce corrections. Mark an unknown as an unknown and run a
small test before making it a large allocation.

## Give one lane priority

Choose one primary lane from the options that remain. Primary does not mean permanent or
exclusive. It means this is the lane whose sourcing, venue, records, and weekly work receive
priority during the next review period.

Focus is useful because the scarce resources are shared. Cash split across unrelated holds is
not available for the next buy. An evening spent learning a second intake process is not
available to clear the first backlog. A primary lane lets repeated work build usable evidence:
actual conversion time, error rate, owner hours, and contribution under your conditions.

A supporting lane is reasonable only when it has a distinct job and does not compete for the
same scarce resource. Keep it inside the unallocated remainder of the inventory pool, with its
own cap and review trigger. If you cannot name the job and guardrail, it is not a supporting
lane; it is drift.

## Set the control rules

Turn the choice into boundaries before making the next purchase.

First, cap the allocation. The cap is the maximum total amount or percentage of the
already-isolated inventory pool assigned to this lane during the review period. It is separate
from a maximum single-buy rule.

One simple policy is:

**Lane allocation cap = inventory pool for this review period × chosen maximum share**

Suppose the provisional inventory pool is \$5,000 and you decide that an unproven lane may use at most 40
percent. Its cap is \$2,000. Every number in this illustration is invented; 40 percent is a
reader-chosen limit, not a recommendation. You may instead set a fixed dollar cap if that is
easier to enforce.

Second, state the expected conversion window. This is the period in which inventory should
normally return as cleared cash under the planned venue and price policy. It is a testable
expectation, not a promise. Measure the actual result and revise the thesis from evidence.

Third, define the lane-loss limit as the maximum modeled loss across the lane's open inventory at
one review point under a conservative exit case. It is a current-exposure boundary, not a running
total of losses already realized. [Chapter 5.2](/chapters/5-2-bankroll-discipline) combines it with a separate whole-operation limit for
one policy period.

Finally, decide what triggers reassessment. Pause new purchases and review the evidence when:

* actual conversion repeatedly exceeds the window;
* processing demand breaches the weekly labor limit;
* the conservative exit case exceeds the lane-loss limit; or
* the lane reaches its allocation cap without producing the expected result.

Choose the response from the evidence: reduce the allocation, narrow the product scope, change
the exit plan, or leave the lane. Record the change rather than silently rewriting the original
thesis.

## Write the inventory thesis

Finish with one paragraph:

> My primary inventory lane is \_\_\_ because it fits my \$\_\_\_ inventory pool for this review period,
> \_\_\_ weekly hours, and a normal cash-conversion window of ***. I will allocate no more
> than \$*** or \_\_\_ percent to it, and my lane-loss limit is \$\_\_\_. I will review the result on \_\_\_
> after measuring \_\_\_. I will pause, reduce, or exit the lane if \_\_\_.

If you use a supporting lane, add:

> Its only job is ***. Its cap is \$*** or \_\_\_ percent, and I will reassess it when \_\_\_.

This is a working policy, not an identity. Part 4 begins by turning the chosen lane and its
limits into a repeatable stream of qualified inventory.
