Reseller aging report — how long has your money been asleep? (3D shelf)

The aging report Four bands, counted two ways

0–30 days: items · cost ($)

31–60 days: items · cost ($)

61–90 days: items · cost ($)

Over 90 days: items · cost ($)

Not yet listed (float + drafts): items · cost ($)

The headline

Over 90 days — share of items —

Over 90 days — share of cost —

Your shelf, by age — drag to turn it (or use the arrow keys)

Oldest stock on the bottom shelf, newest on top; each shelf is labelled with its age band, item count and cost. A box is one item (up to 24 per shelf), drawn bigger when that band's items cost more on average. Hover a box for its band, or open the table under the shelf for every figure.

The report needs JavaScript. By hand: for every item still listed, days listed = today's date minus the date it first went up; put it in 0–30, 31–60, 61–90 or over 90; add the not-yet-listed stock as its own line. Count each band and add up its cost. Over-90 share of cost = over-90 cost ÷ total cost — the number to put on your weekly log and watch fall.

Building this report — and the dated protocol that clears each band — is chapters 7 and 8 of Reselling — Intermediate →

How to read it Count it twice: by items, then by dollars

A listing looks the same on day 3 and day 300, so memory fills the shelf in with the recent things — and the old ones go uncounted. Counted by items, old stock can look like a few stragglers. Counted by what you paid, it is often most of your money, because the things that sit tend to be the dear ones you bought with the most confidence.

A worked example

The defaults are the book's: 59 items, $695 at cost. Over 90 days: 23 items — 39% of the items but 61% of the money. Ninety days matters because by then the sold listings you priced against have rolled out of the standard sold filter, and the listing has been through about three monthly renewals without a buyer: the price is unchecked, and the item has become a decision you owe.

Common questions

What do I do with the over-90 band?

Give every band a dated action: refresh at 31 days, offer and step down to your floor at 61, and at 90 ask one question — if this were handed to you today for nothing, would you list it here, at this price, and hold it to a date? If not: move it, lot it, price it to go, or donate it, by a date.

Does old stock cost me fees?

On eBay, at small sizes, mostly not — monthly renewals count against the free-listing allowance. The real cost is the cash: every dollar on the bottom shelf is a dollar your next Saturday can't spend.

This report comes from a book.

It's the low point of Reselling — Intermediate — and the next chapter is the protocol that turns the pile into a process.
