Lost lines: the orders a stock-out turned away, by branch and by account

How an industrial distributor measures the order lines it could not fill from the order and fulfilment exports: cancelled, substituted and short-shipped lines per branch and per account, the value at the line's price, the items that recur, and the accounts whose order frequency fell after a run of lost lines, so that the stock decision is made on what was lost rather than what was sold.

The short answerA lost line is an order line that was cancelled, substituted or short-shipped because the item was not available, from the order export joined to the fulfilment export on order and line. Per branch and per account, the count and the value at the line's price show what the stock position turned away. Items that recur on the lost list are the stocking decision; accounts whose order frequency fell after a run of lost lines are the customer cost, and both come from the same two exports.

A distributor's sales report shows what was sold. The fulfilment export shows what was ordered and not sold, line by line, with the reason. The difference is the demand the stock position turned away, and it is concentrated: a few items, a few branches, and a set of accounts that quietly started ordering elsewhere. This guide sets out lost lines by branch and account, the recurring items, and the frequency effect.

The measures

Per branch, per account, per period:

Lost lines = cancelled for stock + short-shipped + substituted Lost value = Σ ordered quantity not supplied × line price Lost rate = lost lines ÷ order lines

Per item:

Recurrence = periods in the trailing six in which the item had lost lines

Per account:

Frequency effect = orders per week in the 8 weeks after a lost-line run ÷ orders per week in the 8 weeks before

The rows you need

  • Orders: order, line, account, branch, item, quantity, price, date.
  • Fulfilment: order, line, status, reason, quantity shipped, substituted item.
  • Stock: item, branch, date, on hand, where held.

Account identifiers only.

The assertion

Σ order lines = shipped in full + short + cancelled + substituted

A line in no state fails it and is listed.

A worked view

One branch, one quarter.

Item Lost lines Lost value Recurrence Accounts affected
I-2207 41 $38,000 5 of 6 19
I-4471 28 $61,000 6 of 6 7
I-9034 22 $9,000 1 of 6 14

Item I-4471 has been short every period for six months, at sixty-one thousand dollars a quarter across seven accounts. That is a stocking decision with a number on it. Item I-9034 was one bad period and is not.

The account effect

Account Lost lines in run Orders/wk before Orders/wk after Effect Annual value at risk
4471 6 2.1 1.2 0.57 $140,000
2207 4 1.0 1.0 1.00 none
1187 5 3.0 1.8 0.60 $95,000

Account 4471 halved its order frequency after six lost lines in a fortnight, and nobody called, because its revenue is still on the sales report, just smaller. The list is the branch manager's call sheet with a reason on each line.

Where it goes wrong

Lost lines never joined to orders. The fulfilment team knows the count and nobody knows the accounts.

Substitutions ignored. Revenue kept, customer irritated, unseen.

Valued at cost. The customer's price is what was turned away.

Recurrence not tracked. A one-period problem and a six-period problem look the same on a monthly list.

Every month, lost lines and the accounts behind them

Mapped once, the order and fulfilment exports produce lost lines by branch, item and account, the recurrence, and the frequency effect every month. Covirage builds this from the exports as they are. The industrial distributors page describes the setup, and the dormant accounts guide covers the list that accounts with a frequency drop eventually reach.

Questions people ask

How is a lost line identified?

From the fulfilment export's line status: cancelled with a stock reason code, substituted with a different item, or shipped short of the ordered quantity. Where the system has no reason code, a cancelled line on an item with zero stock on the order date is the proxy, stated as such.

Is a substitution a lost line?

Partly. The value moved to another item, so revenue was kept, but the customer did not get what they asked for. Substitutions are reported as their own class, and a customer with a rising substitution rate is on the same watch list as one with cancellations.

How is the customer effect measured?

Order frequency per account in the eight weeks after a run of lost lines against the eight weeks before. An account that ordered weekly and now orders fortnightly, after three cancelled lines, has moved some of its business. The report lists those accounts with the value of the frequency drop.
