Why seed inventory management is unlike any other industry
In most industries, a unit is a unit. A case of auto parts or a pallet of packaged food that arrives in January is the same product when it ships in March.
Not in seed.
Most industries
Seed
Every lot is a little different. Tap a seed to see its lot.
Seed is alive. Every lot is a little different.
Germination declines over time, so you’re constantly retesting and relabeling, and federal rules require the latest test date right on the package. Seed size varies from lot to lot, so you might buy by weight but sell by count.
That’s why accurate, lot-level inventory isn’t just nice to have. It’s what customer confidence is built on. Here’s what makes seed inventory so different, and what your system needs to handle it.
Germination declines, and the clock is always running
Because seed is alive, its most important quality measure doesn’t stay put. Germination can decline over a season, and how quickly depends on the crop, the lot, and how the seed is stored. A lot that tested well after harvest may not test the same way months later.
Federal and state seed laws protect growers through truth-in-labeling. Under the Federal Seed Act, tags on agricultural seed show:
- Kind, variety, and lot number
- Pure seed, other crop seed, inert matter, and weed seed percentages
- The name and number per pound of any noxious weed seeds
- Germination percentage, plus hard or dormant seed where it applies
- The month and year the germination test was completed
- Origin, and the labeler’s name and address
For inventory, the test date matters most. For seed shipped across state lines, no more than five calendar months can pass between the end of the month the germination test was completed and the date the seed ships. Seed in hermetically sealed containers is the main exception. States set their own limits for seed sold within the state, and they vary, so the same lot can be fine to sell in one market and need a retest in another.
That means every lot has a clock running on it. Someone has to know which lots are coming due, pull samples, wait for lab results, and update tags before the seed can ship. When that tracking lives in a spreadsheet, a lot with an outdated test date can slip onto a truck during the spring rush.

Pick the month the germination test was completed
Based on the Federal Seed Act’s five-month limit for agricultural seed shipped interstate. Hermetically sealed seed and state rules for in-state sales differ. Check the rules for each market you sell into.
Buying by weight, selling by count
In most distribution businesses, the relationship between how you buy and how you sell never changes. A case always holds the same number of units.
Seed doesn’t work that way. Seed size varies with growing conditions, moisture, and genetics, so the number of seeds per pound changes from lot to lot. Seed companies often contract with growers and receive raw seed by weight, then sell finished seed by count.
Take corn sold in 80,000-kernel units. Depending on seed size, a unit from one lot might weigh 42 pounds while a unit from another weighs 48. A system that uses one fixed conversion between pounds and units will miscalculate how many units a bin of bulk seed can produce, which throws off availability, warehouse picks, and inventory value.
Getting this right means tracking seed size on each lot and converting weight to count using that lot’s numbers, not an average.

Treatments, blends, and lot genealogy
Seed is rarely sold exactly as it came out of the field. Between harvest and delivery, a lot may be cleaned, conditioned, and sized. It may be treated with a fungicide or insecticide, or given a biological inoculant (such as rhizobia for legumes), a polymer coating, or a micronutrient treatment. Or it may be blended with other kinds and varieties into a mix such as a cover crop or turf blend.
Each step creates a new lot that has to stay connected to the lots it came from. Blends add another layer. A mixture’s tag covers each component, and the germination test date shown for the mixture is the oldest date among its components. So the quality data for a blend depends on knowing exactly which lots went into it.
Trace a bag of cover crop mix back to the field
Select any lot to see what it came from and where it went, or trace the finished bag back to the grower fields.
If a customer has a question about a bag, or a quality issue comes up, you need to trace it back through the blend, the treatment, and the lab results to the original lot and the grower’s field. With complete lot genealogy, you can isolate the affected lots quickly. Without it, one question can turn into a much broader hold or recall than necessary.
Where generic systems fall short
Most business software assumes every unit of an item is interchangeable. It has no natural place for germination results, test dates, or seed size on each lot, and no way to convert weight to count lot by lot.
So teams fill the gaps themselves:
- Lab results in a separate file
- Lot numbers on a whiteboard
- Conversion formulas in Excel
That works until the spring rush, when the gaps show up as shipping delays, inventory counts that don’t match, and compliance risk. If that sounds familiar, our post on why seed companies outgrow their ERP covers the warning signs in more detail.
Managing living inventory with Acumatica and MAE
Acumatica Cloud ERP gives seed companies a flexible foundation with strong lot tracking, traceability, and mobile warehouse tools. MAE, an Acumatica Value-Added Reseller (VAR), configures it around the way seed inventory actually works. That includes:
Lot-level quality data
Germination, purity, seed size, test dates, and origin recorded on each lot, so the information on the tag comes from the system instead of a spreadsheet.
Retest tracking and quality holds
Visibility into lots approaching their test-date limits, and holds that keep seed from shipping until it has been retested and relabeled.
Weight-to-count conversions by lot
Conversions set up so bulk weight translates into sellable units using each lot’s seed size.
Lot genealogy
Traceability in both directions, from receiving through conditioning, treating, blending, bagging, and delivery.
Licensing for the busy season
Acumatica doesn’t charge per user. Pricing is based on the applications you use and the resources you consume, so seasonal warehouse staff and field personnel can have their own access.
Mobile warehouse tools
Staff can scan lots, check lot details, and update inventory from a phone or tablet.
If you’re comparing systems, our guide to evaluating a new ERP for your seed company walks through what to look for and the questions to ask.
Customer confidence starts with the lot
In seed, customer confidence comes from delivering what the tag says: seed that germinates, is true to type, and performs in the field. That starts with knowing exactly what’s in every lot.
