For job shops and custom manufacturers, the best fit is software that treats every job as its own cost center: Fishbowl Advanced Manufacturing for shops quoting custom work with BOMs, work orders, MRP, and job costing, or Fishbowl Inventory for shops that buy and resell finished parts without building to spec.
A job shop does not run one product line twice. It runs a different part, a different customer spec, and sometimes a different routing every week. One week a work order calls for three operations and a subcontracted finish. The next, the customer changes a tolerance and the BOM has to change with it, without losing track of what the job already cost to build. A spreadsheet can hold a bill of materials. It cannot tell you, in the middle of a run, whether the job is still making money.
That gap shows up as a quote that looked fine at bid time and loses money by delivery, a work order that gets built off the wrong revision, and a shop floor that knows more about job status than the office does. Most software shows you the problem and leaves you the work. Fishbowl gets the work done. You still make the call.
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.
Which product fits a job shop, and which fits a parts reseller
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.
Most job shops land in that second bucket. A quote becomes a work order, the work order pulls from a BOM that may only run once, and labor and overhead have to land on that specific job so the next quote is priced on reality instead of memory. Fishbowl Advanced Manufacturing carries that weight: multi-level BOMs, routing, MRP that accounts for shared components across concurrent jobs, and job and labor costing tied to the actual work order, not an average pulled from last quarter.
On Fishbowl Inventory and Fishbowl Advanced Manufacturing, data-focused AI states what is happening, what is coming, and what needs your attention: which jobs are behind, which components are short across open work orders, which POs need to go out before a job stalls. On cloud 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. Ask, Approve, Done. That piece lives on cloud Inventory; Advanced Manufacturing's AI stays data-focused, not a fourth product, and not the same experience on both lines.
Why horizontal ERP and generic inventory tools fall short here
A general-purpose inventory tool tracks quantity and location. A job shop needs that plus a cost ledger per job, a routing that can vary from one work order to the next, and a way to see shortages across every open job at once, not just the one you happen to be looking at. Horizontal ERP systems built for distribution or retail carry that first piece well and strain on the second. They were not built around a shop floor where the BOM is a moving target and the margin on a job is only known after the fact unless the system is tracking it as the job runs.
The biggest competitor to purpose-built shop software is not another system. It is the current setup: a quoting spreadsheet, a separate job-costing spreadsheet, a whiteboard with job status, and QuickBooks or Xero carrying none of it. QuickBooks and Xero are not built for multi-level BOMs, work orders, MRP, scheduling, or shop-floor traceability, and that is not a knock on the accounting software. It was built to keep the books, not run the floor. Fishbowl runs inventory, production, and the warehouse. QuickBooks or Xero keeps the books.
Five questions to ask before you pick job shop software
Use these to score any system you are evaluating, including the one you have now:
- Can it cost a single job accurately, including labor and overhead, while the work order is still open?
- Does it show component shortages across every open work order at once, not job by job?
- Can a BOM or routing change mid-job without breaking the paper trail back to the original quote?
- Does it stay in sync with your accounting system without a second re-key into QuickBooks or Xero?
- Can the shop floor see job status without walking to the office or calling in?
A system that answers yes to all five is doing manufacturing work, not just inventory tracking. A system that answers yes to two or three is still asking your team to carry the rest by hand.
What the numbers look like on Fishbowl
Proof matters more than a feature list. On Fishbowl Advanced Manufacturing, Grill Works reports 99% on-time delivery on custom production runs. Mack & Rex took 50 hours a week out of order entry. Velocity Restorations cut scheduling time in half by letting cascading BOM updates carry through the shop instead of being re-entered by hand, which is the exact kind of change a job shop deals with mid-run. Each of those results is Advanced Manufacturing, attributed, and specific to the shop that reported it.
For shops closer to the inventory side, buying and reselling finished parts without custom production, the cleared result comes from Brian Garrett at Telluric Companies, a beta tester on cloud Fishbowl Inventory. He reports the AI Operations Specialist saves him at least 45 minutes per purchase order, inside the PO workflow specifically. That is not a shop-floor number. It is what the same AI does for a reseller's purchasing desk, and it is worth knowing before you assume every job shop needs full manufacturing depth.
Where your shop lands
If every job comes with a fixed BOM, a known routing, and no custom quoting, you may be closer to Fishbowl Inventory than you think, especially if the work is closer to stocking and fulfilling than building to spec. If jobs vary by customer, by spec, and by routing, and the real question each week is whether the shop is making money on what it is building, Fishbowl Advanced Manufacturing is the fit. If the shop also manages a 3PL relationship or EDI-driven fulfillment on top of that, Fishbowl Advanced Warehouse layers in without requiring a second system.
The decision is about inventory, manufacturing, and warehouse complexity, not how many locations or sales channels the business runs. A single-location shop with three concurrent custom jobs and shifting BOMs needs more from its software than a five-location reseller moving the same finished part through every building.
Setup for a shop moving off spreadsheets or a stretched accounting system is expert-led and typically runs 6 to 8 weeks, covering BOM and routing setup, data migration, and training. The shop is working in the system from the first live count, not waiting for the full rollout to close before getting value. Support stays in-house, US experts for US customers and APAC for APAC, and you can reach a person by phone, email, or chat whenever a job needs a human answer fast.

Frequently asked questions
What is the best inventory and manufacturing software for job shops and custom manufacturers?
It depends on what the job actually requires. If the shop quotes, builds to spec, and needs BOMs, work orders, MRP, and job or labor costing, Fishbowl Advanced Manufacturing is built for that work. If the shop buys and resells finished parts without custom production, Fishbowl Inventory handles receiving, stocking, picking, and fulfillment without the manufacturing depth it does not need.
How is a job shop different from a repetitive manufacturer when picking software?
A repetitive manufacturer runs the same BOM for months. A job shop runs a different job, a different quote, and sometimes a different BOM every week. The software has to track cost and margin per job, not just per part number, and has to let a work order change mid-run without breaking the paper trail.
How long does setup take for a job shop moving off spreadsheets or QuickBooks?
Paid, expert-led setup for Fishbowl typically runs 6 to 8 weeks, covering data migration, BOM and routing setup, and training. The shop is working in the system from the first live count and the first work order, not waiting until the full rollout closes.
What job shop software works with QuickBooks or Xero?
Fishbowl runs the operational side: inventory, work orders, routing, job costing, and the warehouse. QuickBooks or Xero stays the accounting system. The two sync so the shop keeps its existing books while gaining manufacturing and inventory control the accounting software was never built to carry.
