A trading warehouse: keeping the books in step with fast shipping

A wholesale warehouse often receives in the morning, ships all day and does paperwork only in the evening. Fast shipping is good, but the books are always half a step behind: the goods have left the gate and the system still shows them in stock. By the weekend the storekeeper posts from memory, and a slip is hard to spot. Books and stock drift apart, and the year-end count finds differences everywhere. Three habits can keep them in step.

Why the faster you ship, the further the books lag

The cause is almost always the same: goods go first, documents follow.

• At peak times, the person raising documents and the person moving goods are both overloaded, so goods are loaded and the paperwork waits "until later".
• A regular customer or an acquaintance collects goods on a word, and nobody records it.
• Returns, exchanges and samples have no clear procedure, so items are put back or handed out casually.
• The system allows negative stock, so errors do not show up in time.
• Several people share one login, so when something goes wrong nobody can be traced.

An invented example: a trading warehouse ships about 120 lines a day. If 10% of those lines are documented only the next day, about 12 lines lag every day. By Friday evening some 60 lines have physically left but are not yet in the books, and the system shows more stock than exists by the quantity on those 60 lines. (The figures are invented.) Any count will treat that lag as a difference.

Habit one: same-day documents, no document no exit

The most effective rule is a single one: no document, no exit. In practice:

• Set up a "to be documented" bay at the exit. Goods at the door without a document wait there, and the bay must be empty before the end of the day.
• Raise the dispatch document first and then pick: document first, goods second.
• Regular customers and verbal pick-ups need documents too. If there is no time, raise a temporary one and replace it with the formal one that day.
• Each person uses a personal login.
• First thing the next morning, check that yesterday's dispatch documents match the system's issue records one for one.

Habit two: fixed checkpoints

Do not wait for month end. Set a few small checkpoints in the day, for example 12:00 and 17:30, and spend ten minutes at each on three things:

1. Compare today's dispatched documents with the system's issue records for quantity.
2. Look for items with negative stock in the system, and find the cause the same day.
3. Look for goods already loaded but not yet documented.

The lag is then at most half a day, not a week. Record each checkpoint on a simple sheet, and after a few weeks the weak links show clearly.

Habit three: count the fast sellers weekly

In a trading warehouse a small part of the range accounts for most of the shipments. List the twenty or thirty top-selling products as fast sellers, count them at a fixed time each week, say Saturday morning, compare with the system and trace any difference on the spot.

• Counting fast sellers takes only 30 to 40 minutes and does not disturb business.
• Write down the cause of every difference, and look for a pattern when the same product keeps going wrong.
• Other products rotate through spot checks by ABC class and need not be counted weekly.
• Weekly results are summed up in the monthly stock report.

Linking the three habits

Same-day documents keep the books fresh. Checkpoints expose missed documents on the day. A weekly count of fast sellers stops physical deviations building up over a month. Together they form a small loop in which each layer reduces the burden on the next.

With the same invented figures: before the habits about 60 lines lag by Friday. With same-day documents and checkpoints, late lines fall to 1 or 2 a day and are cleared at the afternoon check. Differences in the weekly fast-seller count fall from a dozen or so at first to single figures. (The figures are invented.)

In short

In a warehouse that ships fast, books and stock stay in step through habit, not through one big count at year end.
