MYOB Acumatica Kit Assembly: Stock Kits vs Non-Stock Kits for Australian Distributors

MYOB Acumatica has two kit types, both defined on the Kit Specifications form (IN209500) once the Kit Assembly feature is switched on. A stock kit is built ahead of the sale on the Kit Assembly form (IN307000) and sits on the shelf as its own item. A non-stock kit is never assembled: the sales order pulls its components and the warehouse picks them one by one.

At a glance

• Who it is for: Distributors and wholesalers who sell bundles, starter packs, gift hampers or pre-packed sets as one sales line.
• Problem it solves: Selling a bundle as one item while stock, cost and cost of goods sold stay right for every component inside it.
• Platforms: MYOB Acumatica, Kit Assembly feature on the Enable/Disable Features form (CS100000). Kits sit in Inventory, so they do not need the Manufacturing module.
• Typical cost: Configured inside an implementation rather than bought as a separate project; indicative implementation bands are in our MYOB Acumatica cost guide.
• Typical timeline: Set up during the implementation; the MYOB FastStart Wholesale Distribution program is a fixed-scope 12 week go-live.
• Last verified: 30 October 2026 against MYOB’s Inventory Item Kits help topic.

Kits come up in almost every distribution scoping session we run. Someone in the room says “we do a bit of assembly”, and the next question is whether that means the Manufacturing Edition. For most distributors it doesn’t. Packing a starter kit, a gift hamper or a ten-pack of fittings is kit work, and MYOB Acumatica handles it inside Inventory. The real decision is which of the two kit types fits the way your warehouse works, because that choice changes when stock leaves the shelf, how the kit is costed and what a customer can return.

What is the difference between a stock kit and a non-stock kit in MYOB Acumatica?

MYOB’s own one-line summary is the clearest: the system tracks stock kits in inventory and does not track non-stock kits. Both types can contain stock components (things on your shelf) and non-stock components (labour, packaging or a service line). Everything else follows from whether the kit itself exists as stock.

MYOB calls non-stock kits “virtual kits”, which is a useful way to explain them to a warehouse team. The kit is a recipe and a price, not a box on a shelf.

How do you set up kit assembly in MYOB Acumatica?

The setup is the same shape for both types. The difference is which item form you start on.

• Switch the feature on. Turn on Kit Assembly on the Enable/Disable Features form (CS100000). Without it the kit options don’t appear.
• Create an item class for the kit group. MYOB recommends a class per kit family on Item Classes (IN201000), so posting and tax defaults are set once.
• Create the kit item. A stock kit is created on Stock Items (IN202500), a non-stock kit on Non-Stock Items (IN202000), with the Is a Kit box ticked on the General tab.
• Write the specification. On Kit Specifications (IN209500) you list the stock and non-stock components and their quantities. Each revision can allow extra components at assembly, and each component line can allow a quantity variance.
• Set the price. A default price goes on the kit item. Once you are pricing more than about ten kits, MYOB points you to Sales Price Worksheets (AR202010), the same tool covered in our price classes and worksheets guide.

For a stock kit there is one more step before anyone can sell it. You create a kit assembly document on IN307000, pick the revision and quantity, and release it. Release takes the components out of stock, puts the kits into stock and creates a GL batch. Until then the kit has no on-hand quantity to sell.

What do revisions do?

A revision is a version of the same kit with a small change, such as swapping one supplier’s carry case for another’s. Stock kits can carry several revisions, and kits already built on an older revision can still be sold. Non-stock kits get one revision and you cannot add more, so a changed recipe on a non-stock kit means editing that revision or creating a new kit item.

How are kits costed and posted to the GL?

This is where the two types differ most, and it’s the part finance needs to sign off before go-live.

A stock kit takes its cost at assembly. For every valuation method except Standard, MYOB adds up the stock component costs from the revision, any components added during assembly, and labour or service non-stock components at rate times quantity. Standard-method kits use the standard cost on the kit item, and any gap between that and the component total goes to the Standard Cost Variance account on the kit’s posting class. Non-stock components on a stock kit post their cost to the expense accrual account set by each component’s posting class (IN206000).

A non-stock kit takes its cost at sale. Sales Orders Preferences (SO101000) sets the cost basis to one of three options: the sum of stock component costs, the kit’s own standard cost, or both added together. The first suits a kit made almost entirely of stock items, the second a kit that is mostly service or packaging. When the invoice is released, MYOB raises an inventory issue for the stock components and their cost of goods sold accounts are debited.

The first thing I ask a distributor about kits is when the boxes get packed. If you build them in a quiet week and they sit on a pallet waiting for orders, that’s a stock kit, and you want the assembly document so the shelf count is right. If you pack at the bench while the order is being picked, a non-stock kit is less work and the component stock stays honest without anyone remembering to release an assembly.

Can kit components drive purchasing and replenishment?

Yes, from MYOB Acumatica 2024.1.1, if you run inventory planning. MYOB’s release note on kit components in inventory planning says the components needed for a stock kit on a sales order now count as planned demand, and the stock components of a non-stock kit generate demand when the kit is on a sales order or a forecast. Before that release, users had to create kit assemblies early just to make the components show up.

There are conditions. Inventory planning needs either Material Requirements Planning or Distribution Requirements Planning switched on alongside Kit Assembly. A stock kit needs Kit Assembly as its replenishment source on the Inventory Planning tab of IN202500, and the specification needs at least one active revision. Planners can then select kit rows on the Inventory Planning Display (AM400000) and create the assembly documents from there.

If you don’t run planning, reorder points still work on the components themselves. Our replenishment and reorder points guide covers how those are set per warehouse.

When would you disassemble a kit?

Only stock kits can be taken apart, using the Disassembly type on the same Kit Assembly form. The common reasons are a slow-moving bundle whose components sell better on their own, or a kit whose shortest-dated component is close to expiry. Disassembly must use the revision the kit was built on, MYOB estimates the component quantities and lets you adjust them, and a reason code of the Assembly/Disassembly type records any difference between the kit’s cost and the cost put back on the components.

Which kit type should a distributor choose?

Most of the distributors we scope end up with both. A practical rule:

• Choose a stock kit when the kit is built ahead of demand, carries its own barcode or batch, needs to show as available stock to your sales team or ecommerce channel, or has a shelf life you track at kit level.
• Choose a non-stock kit when the kit is assembled at pick time, changes with promotions, is mostly a pricing bundle, or when customers may return one component rather than the whole pack.
• Look at Manufacturing instead when the work needs routings, work centres, labour tracked against an order or scheduling against capacity. Our Distribution Edition vs Manufacturing Edition guide draws that line in more detail.

Watch-outs we check before go-live

• Whole-number components. If a stock component’s base unit has Divisible Unit cleared on IN202500, kit quantities must be integers. A non-stock kit shipment that breaks the rule either won’t save or lands on hold, depending on the Hold Shipments on Entry setting.
• Serial numbers. Serial-numbered components can only go into serial-numbered stock kits. Non-stock kits cannot use lot or serial components with the When-Used assignment method or the User-Enterable issue method.
• One revision on non-stock kits. Plan the item naming so a recipe change doesn’t strand open sales orders.
• Over-issue needs a reason code. If an item class allows negative quantities, an assembly line that exceeds on-hand needs an Assembly/Disassembly reason code. Set a default on Inventory Preferences (IN101000) so the warehouse isn’t stuck at release.
• Tax on mixed bundles. A hamper that mixes GST-free food with taxable items needs its tax set-up tested on a real invoice before go-live, and your accountant should confirm the treatment.

Kits are one of the areas where a well-configured system saves a distributor real time in the warehouse, and one where a rushed set-up shows up as stock counts nobody trusts. We walk through both kit types with the warehouse and finance teams together during scoping, which is part of how we approach ERP for wholesale distribution in Australia.
