Why and How DSOs Should be Keeping Track of Inventory

June 30, 2026

Walk into most dental supply closets, and you will likely find some variation of products ordered by habit, stock levels set by guessing, and a reorder process that depends entirely on whoever happens to notice the shelf is low. 

At one practice, that system works well enough to get by. Multiply it across 20 or 50 locations, and you have a margin problem disguised as an operations problem.

Supply spend is one of the largest controllable costs in a dental group, and for many DSOs, it is one of the hardest to get full visibility into. Inventory management at scale is not about counting more often. It is about knowing what every location holds, how fast it moves, and what you are paying for it, so capital is not sitting idle on shelves. This article breaks down what inventory management means for a multi-location group, how to count and track it, and which metrics are worth watching once you have the data.

How should inventory management work with a dental group

Inventory management is the process of tracking what supplies each practice has on hand, how quickly it uses them, and when to reorder. When it is done well, it connects day-to-day ordering to your financial metrics and gives you a clear view of where your spend is going.

The whole reason individual practices join a dental support organization (DSO) is to access centralized administrative and operational support, allowing clinicians to focus on patient care while the DSO standardizes the back-office functions. For inventory, that means one team can oversee purchasing, negotiate pricing, and design the process while individual locations execute it.

Why inventory tracking gets harder as you add locations

In a single office, sloppy inventory is a minor inconvenience. Across multiple sites, the same problems will quickly compress margins and tie up cash.

  • Consumption varies by location, so a single par level across the board will not solve the problem. A pediatric-heavy office goes through different gloves, composites, and fluoride than a perio-heavy practice, meaning a group-wide par level guarantees some sites end up short while others sit on excess stock.

  • Identical items get ordered under different SKUs or from different suppliers, which breaks spend reporting. When locations use vendor-specific item numbers or homegrown descriptions, central reporting cannot see true volume by product, which weakens your leverage in vendor negotiations.

  • Capital sits idle as overstock multiplies across every site. If every office carries “just in case” quantities of impression material, your working capital is scattered in a closet instead of on the balance sheet.

  • Stockouts trigger rush orders at full price, erasing any negotiated savings. Without reliable counts and reorder points, offices order late, pay for expedited shipping, and sometimes buy off-contract to keep operations running.

  • Leadership has no single view of what members of the group actually holds. Without normalized SKUs and system-level visibility, finance and operations teams cannot answer basic questions like “What is our total inventory on hand?” or “Where are we overstocked?”

When inventory goes untracked, you pay for it three times: in higher spending, lost production when items are missing, and capital tied up where it could be put to better use.

How to track inventory: counting methods compared

There is no single right approach. The right method depends on your operation’s size, staff capacity, and tolerance for the disruption that counting inventory requires.

Periodic full count 

All inventory gets counted at once, usually annually or quarterly. Count days are disruptive but necessary. The numbers are accurate when the count closes, but drift as soon as items start moving again. A three-location group that shuts down supply rooms every January to do a full audit is running a periodic count. Works best for small groups that need a starting point, or DSOs that are measuring inventory for the first time.

Cycle counting 

Teams count a rotating subset of SKUs or locations on a set schedule. Effort is moderate and spread over time, integrating into daily or weekly routines. When the schedule and follow-up investigations are consistent, accuracy stays high. A DSO with ten locations assigns each practice a weekly 20-minute count covering one supply category, rotating through the full inventory over 90 days. Best for multi-location groups that need reliable data without shutting down operations.

Perpetual (system-tracked) 

Inventory updates in real time as items are received, transferred, and used. This method delivers the highest accuracy, assuming transactions are logged correctly, and works best when reinforced by periodic cycle counts. A 30-location DSO scans every order into their procurement platform on receipt and logs transfers between offices, so the system always reflects what’s on hand at each location without anyone running a formal count. Best for larger DSOs that want real-time visibility by location, vendor, and SKU.

Reorder point replenishment

Each item carries a reorder point set from its usage rate and resupply lead time. When on-hand quantity drops to that threshold, a simple card order system shows that the item in question is ready for replenishment, so ordering follows actual consumption rather than a fixed schedule. A 30-location DSO sets par levels for high-use supplies at each office and lets the system surface what needs reordering. Best for DSOs that want reliable stock coverage without tracking every transaction.

Scan-to-cart ordering

Staff scan items as they run low, and each scan drops the product into a cart that converts to a purchase order on submission. It removes manual SKU lookup and keeps ordering tied to what offices actually pull from the shelf. A 30-location DSO equips each office to scan low items directly into a shared cart, then routes the order through approval before it goes to the vendor. Best for DSOs that want fast, accurate reordering at the point of use without a formal counting process.

What is cycle counting?

Cycle counting is a continuous inventory practice where a small, rotating subset of items is counted on a regular schedule, keeping the full catalog accurate without requiring a full shutdown. Instead of counting everything once a year, teams count specific SKUs or storage areas daily, weekly, or monthly, compare those counts to the system, and investigate discrepancies.

For multi-location groups, the sweet spot is a perpetual system fed by everyday transactions and reinforced with cycle counting to keep the data honest. Full physical counts then become an exception, useful for go-lives, acquisitions, or occasional audits, rather than a recurring fire drill.

The inventory metrics worth tracking across locations

Raw counts are a starting point. What matters is what you do with the data. These are the metrics worth pulling consistently:

  • Inventory on hand by location — what money is tied up where, which sites are consistently overstocked, and where you can consolidate or transfer stock instead of buying more.

  • Usage rate per item — how fast each SKU moves by practice type and provider mix, which informs par levels, contract tier opportunities, and product standardization decisions.

  • Stockout frequency — where service is breaking down by item, location, or vendor, so you can adjust reorder points or investigate process gaps.

  • Carrying cost of inventory — the true cost of holding supplies, including supply spend as a share of collections, expired and obsolete stock, and the indirect cost of storage and handling.

  • Cross-location variance on the same SKU — where standardization is missing, or behavior is inconsistent, such as one office paying more or consuming far more of an item than comparable sites, which flags training, process, or contract issues.

These metrics are most useful when you can drill from a group-level dashboard down to a specific office, provider, or item, and then act on what you find in the same system that holds the data.

When spreadsheets stop working

Spreadsheets are a valid starting point, especially for a single practice or a small cluster. Many DSOs arrive with a patchwork of shared Excel files that were never designed for real-time control across multiple sites. Past a certain point, the issues become unavoidable.

  • More than a handful of locations. Version control and data consistency become unmanageable as each office maintains its own tab or file with different naming conventions.

  • Shared SKUs that need normalizing. A spreadsheet does not enforce a shared item master, so identical products proliferate under slightly different names, obscuring true volume and pricing power.

  • Real-time reorder triggers. A spreadsheet cannot automatically flag when on-hand falls below par, so teams rely on memory or manual reviews that slip during busy weeks.

  • Audit-ready records. Spreadsheets do not automatically tie counts to purchase orders, receipts, and invoices, making it hard to prove that what you bought is what you received and still hold.

A simple starting framework with Method

Getting supply management under control is less about finding the right software and more about building the right habits. Standardize your SKUs where possible across locations so identical items roll up to one record, and you can see true volume and pricing. Set par levels per site based on local usage and lead times, not a group-wide average. Use cycle counting for critical and high-value items to keep your data reliable between full counts. Connect inventory to purchasing and receiving so reorders run on actual usage, not gut calls to a rep.

From there, more advanced capabilities follow naturally: cross-location transfers, formulary enforcement, and vendor scorecards. But none of it holds together without clear item definitions, consistent counting, and a closed loop between what you hold, what you use, and what you pay.

When your inventory connects to purchasing and receiving, you always know what you have, what you ordered, and what you paid. That foundation is what makes vendor negotiations, formulary enforcement, and spend management possible. 

Method is built for exactly that, connecting inventory visibility to the full procurement workflow so reorders happen on data instead of guesswork, and leadership gets a group-wide view of spend and stock in one place.

Frequently asked questions

How often should a dental practice count inventory? 

A hybrid approach works well for most practices: a full count at least annually, plus cycle counts of high-value and fast-moving items monthly or weekly, depending on volume. DSOs with perpetual systems typically rely on automated transaction tracking and use cycle counts mainly as a control to catch discrepancies early.

What is a par level, and how do you set one? 

A par level is the minimum quantity of an item a location should have on hand before a reorder is triggered. To set one, start from average usage over a defined period, add safety stock based on variability and lead time, and adjust per location rather than applying a single group-wide number. A high-volume surgical practice and a smaller hygiene-focused office will not have the same par for the same item.

What is the difference between cycle counting and a full physical count? 

A full physical count is a one-time event where you count all inventory at once, often pausing normal operations. It gives you a precise snapshot but not continuous accuracy. Cycle counting spreads that work across the year by counting smaller segments regularly, maintaining accuracy with far less disruption and enabling faster correction when discrepancies surface. Method customers gravitate toward Scan-to-cart and reorder tag systems, making it easy to build your list and easy to 

Can a DSO manage inventory in a spreadsheet? 

Early-stage or single-location groups often start there, and it holds up at small scale. Once you introduce multi-location visibility and the need for audit-ready, real-time data, a spreadsheet becomes a liability. At that point, an integrated inventory and purchasing system is the practical next step.
