Bill of Materials in QuickBooks Online: What Works and What Is Missing

If you searched for a QuickBooks bill of materials, you probably make something: mix batches, assemble kits, or turn raw components into finished goods. And you probably discovered that QuickBooks Online has nothing called a bill of materials or an assembly. That is not a settings problem or a plan-tier problem. QuickBooks Online does not include BOMs or assemblies on any plan. This guide explains exactly what QuickBooks Online does support, why the common workarounds break down, what a small manufacturer actually needs from a BOM, and how Evenbatch adds real bills of materials on top of QuickBooks Online for a flat $49.99 per month.

What QuickBooks Online actually supports for BOMs and assemblies

Here are the plain facts about QuickBooks assemblies and where they live in the Intuit product line:

• QuickBooks Online does not include assemblies or bills of materials on any plan. Assemblies are a QuickBooks Desktop Premier and Enterprise feature.
• QuickBooks Online has "bundles." A bundle groups items together on a sales form so you can sell several items as one line. That is all it does. Bundles do not consume components when you build something, do not track builds, and do not roll up costs into a finished item.
• QuickBooks Online Plus and Advanced track inventory quantities and cost using FIFO. That works at the item level. It has no concept of a build, so it cannot connect the cost of your components to the cost of the thing you made from them.
• QuickBooks Online does not support units-of-measure conversion either. Units of measure is a Desktop feature.

For years the standard advice was "if you need assemblies, use QuickBooks Desktop." That advice is aging out. Intuit has stopped selling new subscriptions of most QuickBooks Desktop products to new US customers and retires older Desktop versions on an annual schedule. Many Desktop users are moving to QuickBooks Online as a result, and new businesses in the US mostly cannot buy Desktop at all. If you are in the middle of that move, our guide on moving from QuickBooks Desktop to Online with inventory covers what carries over and what does not. The short version: if your process depends on assemblies, the gap has to be filled by something that sits alongside QuickBooks Online.

Why bundles and spreadsheet workarounds break down

Most small manufacturers on QuickBooks Online try one of three workarounds before looking for real software. Each one fails in a predictable way.

Bundles as fake assemblies. Because a bundle only groups items on a sales form, nothing happens to component stock when you actually build. You produce fifty units on Tuesday, but the flour, bottles, or circuit boards you consumed are still sitting in QuickBooks at their old quantities. On-hand counts drift further from reality with every build. And since no cost flows from components into the finished item, any finished-goods cost you enter is invented, not calculated.

Spreadsheets as the recipe book. A spreadsheet BOM keeps the recipe outside your books entirely. Cost roll-up is a manual exercise you redo every time a component price changes, which means it is usually stale. When the recipe changes, the old version is overwritten and gone, so you cannot answer what a batch built in March was supposed to contain. And nothing ties a build to the specific lots that went into it, which matters the day a supplier calls about a bad ingredient.

Manual journal entries. You can move value from raw materials to finished goods with a journal entry after each build. It is possible, but it is error-prone, it depends on one person remembering to do it, and the entry is not traceable back to a specific production run. Six months later, nobody can say which builds a given journal entry covers.

The symptoms are familiar: negative inventory on components you know you have, month-end counts that surprise you, and no confident answer to the question "what did this batch actually cost us?" None of these are bookkeeping errors. They are the natural result of running production through a system that has no concept of production.

What a small manufacturer actually needs from a BOM

Before evaluating any tool, it helps to write down the requirement set. For a small shop, a real bill of materials system needs to do the following, regardless of which product provides it:

• Component consumption on every build, so raw material counts go down automatically when finished goods go up.
• Scrap percentage, because real yields are not 100 percent and your costs should reflect that.
• Per-unit cost roll-up, so the finished item carries the true cost of the components, not a guess.
• Multi-level structure, so a subassembly can appear as a component in a parent BOM.
• BOM versioning, so an edit made after builds have already happened creates a new version instead of rewriting the history of past production.
• Unit-of-measure conversion, so you can buy in cases and consume in eaches. QuickBooks Online cannot do this itself; see our guide on units of measure with QuickBooks Online.
• Lot-level consumption if you track expiry dates, so every build records which lots it used. See lot tracking with QuickBooks Online for why this matters for food, cosmetics, and supplements.

If a tool checks these boxes and posts clean numbers back to your books, the accounting side takes care of itself.

How Evenbatch adds real BOMs on top of QuickBooks Online

Evenbatch is web-based inventory software built for small manufacturers with one to ten people who run their books on QuickBooks Online. It provides the BOM layer that QuickBooks Online is missing:

• Multi-level BOMs (one to two levels), so a subassembly can feed a parent item.
• Scrap percentage on the BOM, so expected waste is part of the cost.
• Per-unit cost roll-up, so component costs flow into the finished item.
• BOM versioning: edits made after transactions create a new version and preserve history, so past builds always reference the recipe that was actually used.
• Production orders that explode the BOM, consume components FEFO (first expired, first out), and produce output lots with rolled-up cost.
• Per-item unit conversions that apply across purchasing, BOMs, and sales, so you can buy in cases and consume in eaches.
• Lot tracking on every plan, with expiry dates and remaining quantities per lot, feeding a one-click recall trace from any lot to the production runs and shipments it touched.

Pricing is one number: $49.99 per month flat, with unlimited users and every feature included. There are no add-ons and no per-user fees, and lot tracking is never an upsell. You can start a 14-day free trial without a credit card. Details are on our pricing section.

How production posts back to QuickBooks, honestly

A BOM tool is only useful if the numbers land correctly in your books, and only trustworthy if you can see exactly what it writes. Evenbatch connects to QuickBooks Online through Intuit's official API using OAuth 2.0, which means we never see your QuickBooks password. Evenbatch pushes invoices, bills, and production journal entries to QuickBooks, and imports items, customers, and vendors from it, so your production activity shows up in your books without retyping.

We designed the sync to be verifiable rather than magical:

• A preview mode (we call it shadow mode) shows every change before anything is written to QuickBooks.
• A full sync log records exactly what was sent and when.
• Held changes wait for your explicit approval. Nothing is written silently.
• Item sync is create-only, so Evenbatch never overwrites an existing QuickBooks record.

Whatever tool you end up choosing, ask these questions of anything that writes to your books: Can I preview every write before it happens? Is there a log of what was sent and when? Can the tool overwrite or delete records I already have in QuickBooks? Can I hold a change for approval instead of letting it post automatically? Your accountant will thank you for asking, and any vendor should be able to answer plainly.
