Inventory management software for light manufacturing and assembly

Inventory management software for light manufacturing and assembly needs to track components, kits, and finished goods in one place, not three. Fishbowl Inventory handles receiving, stocking, picking, and fulfillment for finished goods and simple builds. Fishbowl Advanced Manufacturing adds bills of materials, work orders, and MRP when the build gets more involved.

A work order says the floor needs forty units built by Friday. The picker pulls the pick list and finds six of one component, none of a second, and a third sitting in a bin nobody relabeled since the last cycle count. The build stalls. The customer waits. Someone spends the afternoon walking the floor with a clipboard instead of running the line.

That is the pattern behind most light manufacturing and assembly headaches: delayed orders because a shortage shows up on the floor instead of in the system, wasted labor spent hunting for parts or re-keying counts between a spreadsheet and QuickBooks, and unnecessary inventory bought as insurance because nobody trusts the number on the screen.

Most software shows you the problem and leaves you the work.

Fishbowl is the platform. Fishbowl Inventory, Fishbowl Advanced Manufacturing, and Fishbowl Advanced Warehouse are purpose-built parts of Fishbowl, matched to how the business runs.

What counts as light manufacturing and assembly?

Light manufacturing covers a wide range of floors: a shop that builds kits from purchased components, a workshop that assembles finished units from sub-assemblies, a fabricator that does one or two operations before a product ships. Building ten units by hand from a kit list is still manufacturing work. It does not become a lesser problem because there is no CNC line behind it.

What separates one light-assembly shop from another is not the size of the building. It is how many components a build depends on, whether those components also feed other builds, and whether a supplier lead time can leave a work order stranded halfway done. A shop building the same five-part kit all day has a different problem than one juggling forty active builds sharing thirty components with three suppliers.

What the software actually needs to track

An inventory system built for this floor has to answer a few plain questions without a phone call to the warehouse:

How many finished kits are on hand right now, and how many are already committed to open sales orders. How many of each component are available once open builds and open orders are subtracted out, not just the total sitting in the warehouse. Where those components physically sit, since a company-wide total can look fine while one building is empty. What happens to component quantity the moment a build is picked or a return comes back, since a return has to land back in the bin, not just in a report.

A spreadsheet can hold a parts list. A spreadsheet was not built to update live as picks happen, purchase orders land, and builds finish across more than one location. That gap is where the delayed order and the extra safety stock come from.

Fishbowl Inventory or Fishbowl Advanced Manufacturing

If you buy finished goods and resell them, Fishbowl Inventory handles receiving, stocking, picking, transfers, and fulfillment. Add Fishbowl Channels when those products sell through Shopify, Amazon, Walmart, or other channels. If you manufacture the product and need BOMs, work orders, MRP, production scheduling, or job and labor costing, use Fishbowl Advanced Manufacturing, with Channels added if you also sell online. If you do not manufacture but need deeper warehouse workflows such as 3PL management or EDI-driven fulfillment, use Fishbowl Advanced Warehouse. Multiple storefronts or owned locations alone do not automatically mean you need Advanced.

Fishbowl Channels is the channel-integrations layer. It works with Fishbowl Inventory, Fishbowl Advanced Manufacturing, or Fishbowl Advanced Warehouse. Advanced customers add ecommerce channels in Fishbowl; they do not also purchase Fishbowl Inventory. Channels is not a live count sitting on top of a cart. It runs order intake, catalog and product listings, image and price sync, fulfillment, carrier integrations, reporting, and forecasting across every channel the business sells through, so a kit sold on Shopify and a case sold on Amazon draw from the same available count instead of two.

Many light-assembly shops fit on Fishbowl Inventory: a defined kit list, components pulled from the same handful of bins, no multi-level bill of materials, no competing work orders fighting over the same part. Once the build depends on a real bill of materials, spins off work orders that need scheduling, or needs job costing to know what a build actually cost in labor, that is the point to move to Fishbowl Advanced Manufacturing.

Where the AI Operations Specialist and data-focused AI fit

On Fishbowl Inventory, the AI Operations Specialist uses live Fishbowl data to prepare purchase orders, sales orders, transfers, receipts, and adjustments for your approval. Nothing is saved or changed without the operator's approval. The AI Operations Specialist works from what is connected to Fishbowl, not every system the business owns. Ask, Approve, Done.

That means the reorder for a low component doesn't wait for someone to notice the count on a screen. The AI Operations Specialist drafts the purchase order from what Fishbowl already knows about usage and lead time, and a person still reviews it before it goes anywhere. The work gets prepped. You still decide.

Both Fishbowl Inventory and Fishbowl Advanced Manufacturing carry data-focused AI that answers plain-English questions about the business: what is happening right now, what is coming based on open orders and current stock, and what needs attention before it becomes a missed date. On Advanced, this includes demand forecasting where licensed. This is not the same experience as the AI Operations Specialist, and it does not prepare purchase orders or sales orders the way the AI Operations Specialist does. It surfaces what matters; a person still decides what to do about it.

What the numbers look like

Brian Garrett at Telluric Companies, a beta tester, says the AI Operations Specialist saves him at least 45 minutes per purchase order, PO by PO, not as a one-time cleanup but as the ordinary way work gets done now. See more results on the Fishbowl case studies page.

For shops that have grown into a real bill of materials and work orders, the numbers come from Fishbowl Advanced Manufacturing customers using data-focused AI on their own data: Hodo Foods cut stockouts by 35 percent, Koken USA cut backorders by 10 percent, and Cascadia Motion lowered inventory costs by 18 percent. Each of those results is an Advanced customer, not an Inventory or Channels result, and each is worth reading in full on the same case studies page before deciding which product fits the build in front of you.

Frequently asked questions

What is the difference between Fishbowl Inventory and Fishbowl Advanced Manufacturing?

Fishbowl Inventory handles receiving, stocking, picking, transfers, and fulfillment for finished goods and simple kits. Fishbowl Advanced Manufacturing adds bills of materials, work orders, MRP, production scheduling, and job and labor costing for builds with more steps and more components. Neither is an add-on to the other; they are matched to how much building the business actually does.

How does the AI Operations Specialist work inside Fishbowl Inventory?

The AI Operations Specialist uses live Fishbowl data to prepare purchase orders, sales orders, transfers, receipts, and adjustments for your approval. Nothing is saved or changed without the operator's approval. It works from what is connected to Fishbowl, not every system the business owns. Ask, Approve, Done.

Can Fishbowl track kits and sub-assembly components across multiple bins?

Yes. Fishbowl Inventory tracks on-hand and committed quantity by location, including component parts that go into kits, across every building the business owns. If the build involves multi-level bills of materials or open work orders competing for the same components, Fishbowl Advanced Manufacturing carries that depth.

How long does setup typically take?

Training is expert-led and typically runs six to eight weeks. Support is in-house, US-based for US customers and APAC-based for APAC customers, by phone, email, or chat. You can reach a person on support calls.
