Every distributor wants fewer wrong orders. Far fewer can say how many they have today. You cannot tell whether a fix worked without a number from before and after, so this guide starts with measurement and then covers four changes that remove common causes of errors.

It does not promise a target rate. The right target depends on your catalog, your customers and your starting point, and you will only know your starting point once you count.

Define an order error

Write the definition down before you count, or the number will drift from week to week. A practical definition: any line where what the customer received differs from what they ordered, at the price they should have paid. That covers:

  • Wrong item, including the wrong size or pack.
  • Wrong quantity, including shorts nobody told the customer about.
  • Wrong unit: a case shipped when they ordered an each, or the reverse.
  • Wrong price on the invoice.
  • Damaged or out-of-date product.
  • Delivered to the wrong customer, or not delivered.

Decide whether you count by line or by order. Line level is more precise: an order with 30 lines and one wrong line is not the same as an order where everything went wrong. Whichever you choose, keep it the same every week.

Measure your current rate

Log every error for four weeks. The sources are credit memos, customer calls, driver notes, returns and reships. For each one, record the order, the line, the type of error, where it started (entry, picking, loading, delivery or pricing) and what it cost.

Then divide. A hypothetical example with round numbers: if you shipped 20,000 lines in four weeks and logged 300 lines with an error, your line error rate is 300 ÷ 20,000, or 1.5%. If 120 of those started at order entry, 150 at picking and 30 elsewhere, you know where to work first.

Do not be alarmed if the first month of honest logging looks worse than you expected. Errors that used to be fixed quietly by a rep or a driver now get written down. That is the log working, not the operation getting worse.

Step 1: Capture the order once, at the source

Every time an order is copied from one place to another (a notepad, a voicemail, an email, the order system), there is a chance to get it wrong. The fix is fewer copies:

  • Let customers enter orders themselves, online or by text, so their own words are the order.
  • Have reps enter phone orders directly into the system during the call, not later from notes.
  • Read the order back before hanging up: item, quantity and unit for each line.
  • Set a clear cut-off for changes, so late changes do not arrive by side channels after picking has started.

The article on the real cost of manual order entry shows how to put a price on re-keying.

Step 2: Make similar items hard to confuse

"Diced tomatoes #10" and "crushed tomatoes #10" sit next to each other in a search list and often on a shelf. If entry or picking depends on reading a short name, mix-ups will happen. Changes that help:

  • Clean up item names so size, pack and variety appear in the same order on every item.
  • Show the pack size and unit on the order line, on the pick list and on the shelf label.
  • Store look-alike items apart instead of side by side. Clear location labels help here.
  • Add a confirmation step where confusion is likely, such as a scan or a tap on the exact line.

Your error log tells you which items to start with. If the same pair of items keeps being swapped, fix those two first.

Step 3: Confirm picks by scanning

If a picker works from a paper list that says "12 cases", a wrong item is only caught at the customer's door. Scanning each case against the pick list catches the wrong item in the warehouse, where it is cheap to fix.

  • Scan the item, and for perishables the lot, as it is picked.
  • Pick by FEFO (first expired, first out), which reduces out-of-date returns.
  • Record shorts at the pick, and tell the customer before the truck leaves, so a short is a known short and not a surprise.
  • Check the load against the order at the dock for high-value or high-error customers.

Step 4: Close the loop every week

An error log only helps if someone reads it. Once a week:

  1. Sort errors by type and by where they started.
  2. Take the biggest group and find its cause. Ten "wrong unit" errors on the same three items point to a catalog or labeling problem, not a people problem.
  3. Fix the cause, then watch that group over the following weeks.
  4. Track errors by picker and by the person who entered the order, privately, as coaching material. Someone with a high count may have the hardest routes or the messiest items, so look at the cause before drawing conclusions.

Driver records matter here. A signed proof of delivery with notes on what was refused tells you which errors reached the door and why.

Put a cost on each error

To decide how much effort a fix deserves, price your errors. For each logged error, add up the credit given, product that could not be resold, the cost of a second delivery and the staff time spent on it.

A hypothetical example with round numbers: if errors cost $80 each on average and you log 75 a week, that is $6,000 a week. If 30 of those started at order entry and a change removes half of them, that is 15 fewer errors and $1,200 a week in this example. Use your own log for both numbers, and measure again after the change instead of assuming it worked.
