The unseen costs for 3PLs are the labor hours your team spends working around missing information: answering "where's my order?", re-keying an order that arrived as a spreadsheet, walking the floor to confirm a count, re-picking something that went out wrong, and assembling invoices by hand. None of it appears on a P&L as its own line, but at the end of the day, you are still paying for it. Our interactive calculator prices eight of these tasks for a 3PL shipping 200 orders a day. The total comes to $423 a day, or $154,410 a year, which is about 6,176 staff hours and three full-time roles.
That number is just an estimate, you can plug in your own numbers to the calculator and get a more accurate estimate for your operation. This article breaks down where each estimate comes from, how to price the tasks in your operation, and what to do to cut those costs.
An unseen cost has three properties: it's paid in labor rather than invoiced by a vendor, it's spread across people who have other job titles, and it scales with order volume.
Visible costs announce themselves. Add a carrier, you get a rate sheet. Lease space, you get a bill. Add a software seat, procurement sees it. But three people spending forty minutes a day chasing order status generates no document at all. It shows up later as overtime, an unplanned hire, or a client who leaves without telling you why.
Labor is where this manifests most immediately. Warehouse labor accounts for roughly 65% of total warehouse operating costs, according to the MHI and Deloitte Annual Industry Report. When most of your cost base is hours, avoidable work compounds fast, and every hour comes out of the margin you priced the client on.
Here is the basic formula we used to calculate the daily cost:
Daily cost = tasks per day × minutes per task ÷ 60 × hourly wage
The calculator prefills every line from the 200 orders a day at the top of the invoice and prices the time at a $25 hourly wage, annualized over 365 days. You can change any of them.
| Line item | Volume | Minutes each | Daily cost |
|---|---|---|---|
| Answering "where's my order?" | 15/day | 10 | $63 |
| Customer communications and tracking lookups | 75/day | 5 | $156 |
| Data entry and client reporting | 20/day | 7 | $58 |
| Inputting orders manually | 4/day | 12 | $20 |
| Looking for inventory | 12/day | 15 | $75 |
| Mis-picks and mis-shipments | 3/day | 24 | $30 |
| Billing and invoice questions | 12/mo | 120 | $20 |
| Onboarding a new client | 2/mo | 45 | $1 |
| Total | $423 |
$423 across 365 days is $154,410. At $25 an hour, that's about 6,176 hours. Against a 2,080-hour work year, three full-time equivalents. Three people doing work that exists because information lives in the wrong place.
The $25 rate is a wage, not your true cost per hour. The U.S. Bureau of Labor Statistics puts the median customer service wage at $20.59 as of May 2024, so $25 is close to market. Once you count taxes, benefits, time off, equipment and supervision, an hour costs you more than that, so the total here is conservative.
365 days assumes you are operating every day. Status questions arrive on weekends, so a full year is fair for customer-facing lines. Floor tasks aren't, though. The calculator has a field for how many days you actually operate, so for a six-day operation, scale picking and receiving to about 313 days.
Your volumes are the main cost driver. Every line starts from the orders a day at the top of the invoice. Pull last month's ticket count, or estimate how many inquiries you get, and divide by working days to get your true volume.
Looking things up is the biggest bucket on the list, and we estimate it at $219 a day. Everything from status inquiries, follow-up communications, and parcel tracking in carrier portals instead of the WMS eats up time for customer representatives.
"Where's my order?" is the one everybody names, and it's expensive per answer because a single answer could take four lookups: the order record, the inventory view, the carrier portal, the client's own account, then reconciling whatever disagrees. The follow-up traffic around it costs more in total, $156 a day against $63, because there is so much more of it. Salesforce and Shopify both call the question "where is my order" one of the highest-volume contact types in ecommerce support, with published ranges between a quarter and two-fifths of inbound volume, climbing at peak.
For a 3PL the sting is different. You're not fielding this from a consumer, you're fielding it from the customer, often repeatedly. Even if your team is efficient in getting back to the customer, simply having to ask is what can show up in a contract review as "communication issues."
Somebody is typing information that already exists in digital form somewhere else. Data entry and client reporting can run $58 a day. Orders that arrive as a file to download, reformat and key in can add $20 per day.
This is the most avoidable cost here and the easiest to miss, because it feels like the job rather than a workaround. Every re-keyed order is a fresh chance to introduce errors, so part of the mis-pick cost starts at a keyboard in the office.
Someone walking the aisles to confirm a count they could have read off a screen (and the cost to repick affected orders) can cost your operation $105 per day.
Aberdeen Group data reported by Supply Chain Dive puts fulfillment accuracy at 99.5% with a WMS against 92% without, and MHI finds a 25% inventory-accuracy improvement for operations running advanced WMS. On a thousand orders a day, that is 75 recovery events instead of 5.
There are two main categories here: assembling invoices from spreadsheets can cost $20 a day, about $7,200 a year, and client onboarding that can cost around $450 a year.
Manual billing costs more than the hours. It delays cash, and it under-bills rather than over-bills, because extra handling nobody wrote down is extra handling nobody charges for.
Then keep the file and re-run it in two quarters to see where trends show up.
The cheapest status question is one that nobody has to ask, they can find it themselves. When order, inventory, carrier and billing data sit in one place, it doesn't take ten minutes searching through four systems to find an answer for a client.
Averitt Express used Extensiv's WMS to improve their operational efficiency and decreased labor costs by 25%, getting 60 picking hours a day back. With that move, they got carrier tracking, rules-based billing, a client self-serve portal, and automated billing management in one place.
None of those features make work vanish, but they help your employees (and customers) get answers on demand, in one place. That distinction matters, because plenty of software just moves the lookup and calls it a saving.
Order-status labor is the largest cost. Answering "where's my order?" plus the follow-up client communication accounts for $219 of the $423 daily total in Extensiv's example, more than half, because each answer means reconciling several systems.
Tasks per day, times minutes each, divided by 60, times your hourly rate. Annualize by the days the task actually happens. Report hours and full-time equivalents next to the dollar figure.
It's the wage the calculator prefills, and it's close to market: BLS puts the median customer service wage at $20.59 as of May 2024. It's not your true cost per hour, though. Burden adds roughly 25% to 40% on top of whatever you pay, once you count taxes, benefits, time off and supervision, so a loaded $25 wage sits nearer $31 to $35, and the total goes up with it. Calculate your own from loaded payroll divided by hours.
Product cost varies by client and by SKU and counting only recovery labor keeps the figure conservative. We recommend adding your own unit cost and returns freight for the full picture.
Some do, some shrink. Tracking in the WMS eliminates carrier-portal lookups. Automated billing eliminates spreadsheet assembly. Scanning and directed picking reduce error rates and integrations cut manual order entry.
Once a quarter, or any time your order volume moves more than about 20%. These costs scale with volume.
Pricing the unseen costs for 3PLs is useful for one reason: every hour of unseen costs is margin leaving the building that isn't called out on a P&L sheet.
Extensiv brings order status, inventory, carrier tracking and client billing into one system, so the lookups stop being someone's job and the margin stays where you earned it. Request a demo to see it live.
