Cycle Count Accuracy in Assembly: Knowing What You Have Before You Build

When the real bottleneck is not labor, it is inventory truth

Most brands blame labor when assembly work slows down. It is an easy target. You can see people on the floor. You can see lines forming and tables filling up. The quieter problem is harder to spot: inventory that does not match reality. Kits that cannot start because components are missing. Relabeling projects that stall because no one is sure how many units are truly in the building. Cycle count accuracy in assembly is about fixing that. It is the discipline of knowing exactly what you have before, during, and after the work.

By the time leaders start asking serious questions about accuracy, they usually have some scars. As Maureen Milligan explains, "Most of the customers who come to us from another 3PL, their challenges have always been access to their data, order accuracy and efficiency, and basically just meeting the committed requirements." She adds, "Even when they were getting their new inventory delivered to the warehouses, they weren't getting received and on the shelves in a timely fashion to satisfy customer orders." If you cannot trust the numbers on basic inventory, you definitely cannot trust them once assembly and kitting projects start moving things around.

How assembly work quietly wrecks inventory numbers

Even in a solid operation, assembly work can be brutal on inventory accuracy. Traditional cycle counting is built around static storage. You count what is on a shelf or in a bin. Assembly ignores that boundary. Components leave locations, sit on carts, move through stations, and come back as finished goods in new locations with new item numbers. Every one of those touches is an opportunity for the numbers to drift away from reality if you are not careful.

Poor visibility shows up in familiar ways. Teams think they have enough components for a subscription run, then discover halfway through that they are short. Retail display builds get paused because there are fewer units on hand than the system claims. Marketplace prep work gets delayed while someone hunts for inventory that exists in reports but not on the floor.

Retailers notice the downstream impact. Joel Malmquist points out, "Walmart's pretty intense with their labeling rules. Dick's Sporting Goods is the same; if you don't do it right, you get those massive chargeback." Wrong counts and misbuilt packs feed directly into those penalties. If cycle counts are not keeping up with assembly reality, it is only a matter of time before a receiver catches the mismatch.

What cycle count accuracy in assembly really means

Cycle count accuracy in assembly is not just counting more often. It is designing your whole approach to inventory so counts, scans, and workflows reflect how work actually happens. That starts with tight control at receiving, then follows components through storage, picking, assembly, and finished good staging.

Bryan Wright gives the baseline expectation: "A bad WMS system will not track inventory 100%, as it should." Cycle count accuracy assumes the opposite. "A good WMS tracks inventory through the warehouse at every point that you touch it." That includes every time a component leaves a bin for kitting, every time a partially built kit moves between stations, and every time a finished unit is received back into stock.

In that world, cycle counts are not there to fix giant gaps. They are there to confirm that a tightly controlled system is working. When you spot a discrepancy, you know it points to a specific process problem, not a general fog over the whole building.

Why spreadsheets and once-a-year physicals are not enough

It is tempting to lean on annual physical counts to clean up whatever assembly has done to your numbers during the year. The problem is simple. You cannot run a reliable assembly and kitting operation on bad data for eleven months and hope to fix it all in the twelfth. Project decisions happen every week, sometimes every day. Without accurate counts, every yes you say to a retailer, marketplace, or promotion carries more risk than it should.

Maureen sees the pattern play out across providers: "Most of the customers who come to us from another 3PL, their challenges have always been access to their data, order accuracy and efficiency, and basically just meeting the committed requirements." Assembly heavy environments amplify those problems. The more often you touch inventory, the faster those small inaccuracies compound.

Bryan ties it back to systems: "A bad WMS system will not track inventory 100%, as it should." If the system is not designed to treat assembly moves as real inventory events, you will be left with manual adjustments and side spreadsheets. That is the opposite of cycle count accuracy.

The founder's fear: saying yes to projects with shaky numbers

Founders do not just worry about whether they can physically do the work. They worry about whether they should agree to it in the first place. A subscription box expansion, a new retail program, or a special marketplace bundle all look attractive until you realize you are not sure how many components you really have.

Joel hears that concern when customers talk about big, time bound orders. One asked him, "Say Target drops 10 POs and gives us 48 hours to turn it around? Is G10 the right partner for us to navigate through that and execute at a high level?" Underneath that question is a deeper one. Will you discover halfway through that counts were wrong.

Joel explains how his team responds when both speed and certainty matter: "We are able to help them get through that big surge and develop and grow their business as it comes in." Cycle count accuracy in assembly is what makes that credible. Surges are manageable when you know the numbers are right. They are terrifying when every pick list feels like a guess.

Holly Woods offers a ground level view of what that pressure looks like in practice: "Our supervisor, warehouse manager, and several employees worked that entire day into the night, came back in in the morning at 5 a.m. to make sure that we had the routing completed for that pickup for Target." When people are working those kinds of hours, the last thing you want is a surprise shortage caused by bad counts.

Designing cycle counts around assembly reality

Improving accuracy in assembly heavy environments starts with accepting that traditional location based cycle counting is not enough. You still need it, but you also need counts tied to work in process and finished goods that are constantly changing.

Scan based design is a key part of this. Every movement in and out of assembly jobs should be scanned so the WMS can track changes automatically. Cycle counts then become a way to test that those scans are happening correctly, not a patch for missing data.

Jen Myers talks about the system side of growth: "Helping people grow, part of that is the channel expansion and having a warehouse management system, WMS, that supports that seamlessly." She continues, "Everything has to be connected." Cycle counts are one way to confirm that connection is real. If inventory numbers stay tight even as assembly work ramps up for new channels, you know the system and the scans are working.

On the services side, John Pistone explains, "We have created these other value-added services." He makes it specific: "I can kit for them. I can bundle for them. I can build an Amazon seller central account, and I can do all the content build-up." Each of those services touches inventory. Cycle count accuracy in assembly is what keeps that web of activity from turning into a tangle.

Cycle count accuracy inside omni channel operations

Omni channel strategies depend on shared inventory. The same components and finished goods often support D2C, marketplaces, and retail accounts at the same time. That is why cycle count accuracy in assembly matters so much. Every kit built for one channel affects what is possible for the others.

Jen points out that this is exactly when a strong WMS matters most: "Helping people grow, part of that is the channel expansion and having a warehouse management system, WMS, that supports that seamlessly." When counts are tight, you can make smarter decisions about where to point scarce inventory. When counts are fuzzy, you end up overcommitting to one channel and starving another.

For marketplaces like Amazon, cycle count accuracy also supports confident prep and replenishment. If you know exactly how many units are ready and how many components remain for new builds, you are less likely to run out of stock mid promotion or ship partial loads that undercut your ranking.

Visibility that makes accuracy feel real, not theoretical

It is one thing to say that counts are accurate. It is another to show it. Brands need more than a quarterly report. They need daily, even hourly visibility into how assembly work is affecting inventory. That means clear views into components on hand, work in process, and finished goods by channel and project.

Bryan describes the visibility layer that enables this: "We have portals that show you the data. We have history that shows you all of that tracking. It shows the product landed on the dock at 8 o'clock." That same history shows when those products moved into assembly jobs, how many units came out, and how those changes affected available inventory.

Maureen explains how customers respond when they can see that motion: "They can actually watch those progressions going on." When you can watch counts fall and rise in sync with real work, accuracy stops being a promise and starts being an observable fact.

Culture that respects numbers even when days are long

Cycle count accuracy in assembly does not come from software alone. It comes from a culture that treats numbers as non negotiable. That means scanning even when you are tired, counting when you would rather guess, and fixing mismatches instead of ignoring them.

Mark Becker captures the leadership mindset that supports that culture: "Yeah, I live in the grind every day." That grind includes the unglamorous work of tying out counts, investigating variances, and adjusting processes so the same errors do not happen again.

Bryan sets the bar for critical projects: "You go 110% and make sure that when they're done, this project is something they're going to remember." Building a cycle count program that actually works in an assembly heavy environment is one of those projects. It is not flashy, but it changes what is possible later.

When gaps do show up, Maureen describes the response: "We say, We made a mistake, this is what happened, this is how we're correcting, it and this is how we're going to make it right by you." That attitude turns cycle counting from a blame exercise into a learning exercise.

Why cycle count accuracy in assembly becomes a growth enabler

On a surface level, cycle count accuracy in assembly looks like an accounting concern. In practice, it is a growth concern. Accurate numbers give you confidence to say yes to bigger programs, new channels, and more complex bundles. Inaccurate numbers force you to hedge, delay, or over produce to compensate for what you do not know.

It ties directly back to Connor Perkins's simple framing: "To be successful and grow rapidly you have to sell a lot of your products. That boils down to having a good product, but also having a good supply chain." Cycle count accuracy strengthens that supply chain at the point where it is easiest to lose control: in the middle of active assembly, kitting, and light manufacturing work.

If your leadership meetings include too many conversations that start with We think we have enough and not enough that start with We know where we stand, it might be time to treat cycle count accuracy in assembly as a core project, not a side task. The brands that do that can grow more aggressively, because they are building on numbers they can trust.
