Accurate inventory is the difference between shipping on time and overselling stock you don't have. But how you count matters as much as whether you count. This guide compares the two main approaches, then shows how Teamship's new Inventory Counts feature handles both without stopping the warehouse.
Inventory (wall-to-wall) counts
An inventory count, also called a physical or wall-to-wall count, stops operations while every SKU in the building is counted at once, usually annually. It's thorough but blunt: you pause shipping, pull staff off normal work, and you only learn about discrepancies once a year, long after the root cause happened.
Full inventory counts still have a place. Auditors ask for them, some client contracts require them, and a full count is the honest reset button after a messy period. The problem is using them as your only accuracy tool.
Cycle counting
Cycle counting counts a small, rotating subset of inventory on a regular cadence, so the whole facility gets covered over time without ever shutting down. Its big advantage is the feedback loop: when a discrepancy shows up, the receiving or putaway error that caused it is recent enough to actually find and fix.
The comparison at a glance
| Inventory count | Cycle count | |
|---|---|---|
| Frequency | Once or twice a year | Continuous, small batches |
| Operations | Paused or throttled | Keep running |
| Labor | All hands, overtime | A counter or two per shift |
| Error detection | Months after the cause | Days after the cause |
| Audit trail | One snapshot a year | Rolling, always current |
| Best for | Audits, contract requirements, resets | Day-to-day accuracy |
Most growing warehouses land on the same answer: cycle count as the routine, full inventory count only when someone external requires it.
The 3PL wrinkle: counting other people's inventory
For a 3PL, counting is harder than the textbook version. Stock belongs to different clients, a client may ask for a count of their inventory only, and the count evidence needs to hold up when a client questions an invoice or a shortage claim. A paper count sheet, or a spreadsheet reconciled at a desk three days later, satisfies nobody.
That's the gap our new Inventory Counts feature was built to close.
How Inventory Counts work in Teamship
Teamship now runs the whole count inside the WMS, from planning to variance report, whether that's a full wall-to-wall inventory count or a small rolling cycle count: the same feature flexes to either scope. Here's what that looks like in practice.
Count your way, with reusable templates. An admin defines who, where, and what to count: the whole warehouse, specific zones or aisles, or a hand-picked list of locations. Counts can cover every client's stock or filter to a single customer, which means a client-requested count is a few clicks, not a project. Definitions are saved as templates, so next month's count launches in seconds.
Blind or visible, your call. In a blind count, the counter never sees what the system expects, they just scan and enter what's physically there. That removes the temptation to "confirm" the expected number instead of counting. Prefer speed over rigor for a low-stakes count? Switch the same template to visible mode.
Scan-verified, step by step. Counters work on the device already in their pocket or on their cart. At each location the app walks them through the same kind of guided sequence Teamship uses for receiving: confirm the bin, scan the product, enter the quantity, and capture serials, lots, or LPNs when the SKU calls for it. Every line records who counted it and when, so the audit trail writes itself.
Guided routes, parallel counters. Assignments split a count across multiple people, by zone or by exact locations, and each counter's list is ordered along the warehouse's travel path so nobody zigzags. Counts pause and resume cleanly across shifts, and several counters can work the same count at once without stepping on each other.
No shutdown required. This is the part that makes true cycle counting possible: when a count launches, Teamship takes a timestamped snapshot of expected stock, and the warehouse keeps operating. Picking and putaway continue while counters work. Differences are computed against the snapshot, and any line where stock legitimately moved mid-count gets flagged as possible in-flight movement, so your team doesn't chase phantom variances.
Surprises get recorded, not rejected. Scan a SKU that isn't supposed to be in that bin and Teamship accepts it and tags it as unexpected or misplaced. A count that can't record surprises isn't a count, it's a formality.
A variance report you can act on. When the count completes, you get one line per SKU and location: expected versus actual, the differential, captured attributes, who counted it, and when. Filter to variances only, to one customer, or to a zone, then export the CSV for whoever posts the adjustments. When a client asks "are you sure?", the answer is a report, not a shrug.
Getting to 99%+ accuracy
Whatever system you use, the pattern that reaches high accuracy is consistent:
- Count small and often. Daily or weekly batches beat monthly marathons.
- Prioritize what moves. Fast-movers and high-value SKUs earn more frequent counts.
- Go blind by default. Honest counts surface real problems.
- Investigate variances immediately. The value isn't the count, it's fixing the process that caused the miss.
- Track inventory record accuracy (IRA), the percentage of counted locations that match the system. Below ~97% usually points to a process problem upstream, not a counting problem.
Cycle counting turns inventory accuracy from an annual event into a daily habit, which is exactly what keeps stock reliable as order volume grows.
See it on your own stock
If counts at your warehouse still happen on paper, or your accuracy number is a guess, this is one of those features that pays for itself in the first client dispute it settles.
