ERP Software for Manufacturing
One database holding the quote, the bill of material, the job, the inventory transaction, and the ledger entry that follows from them.
Enterprise resource planning software is the system of record that ties finance to operations on one database. For a discrete manufacturer that means the quote, the bill of material, the job, the inventory transaction, the purchase order, and the general ledger entry all reference the same data rather than four exports.
The system of record for quotes, jobs, inventory, and the ledger.
Most shops that go looking for ERP software are not replacing an ERP. They are replacing a quoting spreadsheet, a separate inventory list, paper travelers, QuickBooks, and the person who reconciles all four. WorkCell keeps them in one place: a quote becomes a job, the job carries the bill of material and routing revision it was actually released to, operators report labor and quantities at the machine, and every posting that results is stamped with the Job it belongs to. That is why job cost is current rather than discovered at month end. The ledger, inventory in pieces, purchasing, and the quality record share the same tables, so there is no nightly export to argue with on Monday morning.
Discrete and mixed-mode manufacturers from roughly ten to a thousand employees — machine shops, fabricators, assemblers, and build-to-print suppliers running high-mix work where every job has its own routing and its own cost.
The estimate is built in a spreadsheet by whoever has been here longest, using cycle times that were last checked three years ago. Nothing compares the quoted hours to the hours the job actually burned, so the same part is underbid again on the next release and nobody can point to the reason.
Labor is on timecards, material is on receiving paperwork, and the burden sits in a spreadsheet the controller maintains. The true cost of a job surfaces weeks later during month-end, long after the moment it could have changed a price, a routing, or the decision to take the work at all.
Production reports one quantity complete, inventory shows another, and accounting posts a third after adjusting for what it was told. Each number is defensible in its own system. None of them reconcile, and the argument repeats every month because the systems were never reading the same transaction.
On-hand quantities are typed in weekly, units are mixed between feet and pieces, and nothing records a lot or a serial. Purchasing orders material that is already on the rack, and a containment question about a suspect heat lot becomes a week of pulling paper travelers out of a cabinet.
Inspection results are in one workbook, nonconformances in an email thread, corrective actions in a binder. The data exists but it was never attached to the job, the revision, or the lot it judged, so proving traceability means reassembling it by hand for every audit and every customer complaint.
Quoting and estimating that feed the job
Estimates are built against real routings and material, then released into the job that executes them. Because actuals post back against the same structure, the gap between quoted and actual hours is a number you can read rather than a feeling the estimator has.
Multi-level BOMs and routings, versioned
Bills of material and routings carry revisions with effective dating, and a change supersedes rather than overwrites. A job built last quarter still shows the structure it was built to, which is what configuration control needs and what a general ledger alone cannot give you.
Job costing stamped on every posting
Every posting carries a Job cost object — labor from the floor terminal, material issued from stock, purchases received against the job. Cost accumulates as the work happens instead of being allocated backward from a month-end spreadsheet.
Inventory in pieces with unit conversion
Stock is tracked as discrete pieces, with conversion between purchase, stock, and issue units so a bar bought in feet and issued in pieces stays one balance. Lots and serials are carried from receipt through issue to completion.
The quality record attached to the job
AQL sampling plans and inspection templates drive what gets checked, failures raise a severity-classified nonconformance, and systemic problems escalate into an 8-D corrective action. All of it hangs off the job and the lot it came from.
A real ledger, not an export
General ledger, accounts payable, and accounts receivable sit in the same database as the job, with multi-currency on purchases and sales. QuickBooks Online is supported as a live integration for shops that keep their books there.
Quotes and estimates that release straight into the job that builds them.
EngineeringMulti-level bills of material and routings, revised with effective dating.
ProductionJobs, finite capacity scheduling, and operator terminals at the machine.
AccountingGL, AP, AR, and multi-currency on the same tables as the job.
MRP is one calculation that an ERP may contain: explode demand through the bill of material, net against on-hand and on-order, offset by lead time, emit planned orders. ERP is the surrounding system of record — the ledger, the job, the inventory balance that the calculation reads.
ERP vs MESERP decides what should be made and what it costs. MES is what happens at the machine: the operation dispatched, the quantity and scrap reported, the time clocked, the genealogy captured. ERP is the plan and the money; MES is the record of execution feeding it.
ERP vs APSERP tells you a job is due in three weeks. APS sequences it against finite machine and labor capacity and tells you whether three weeks is possible. Classic ERP order dates assume infinite capacity, which is why shops bolt a scheduler onto one.
ERP vs QMSA QMS owns inspection plans, nonconformances, and corrective action. An ERP owns the job those records belong to. Keep them apart and the inspection result lives in a system that does not know which lot or serial it judged.
Low-volume builds where the quality record and the part genealogy have to survive the audit.
Metal ManufacturingHigh-mix machining and fabrication where every job carries its own routing and cost.
Industrial EquipmentDeep multi-level assemblies that need versioned bills of material, not a flat parts list.
Medical DevicesLot and serial traceability plus inspection records tied to the revision built.
ElectronicsComponent-level bills, revision churn, and inspection at the operation.
The execution layer that captures labor, quantities, scrap, and inspection at the machine.
APSFinite capacity scheduling, including proposal runs a planner can test before committing.
QMSInspections, nonconformances, and 8-D corrective action tied to the job that produced them.
MRPThe material planning calculation underneath ERP, and how the netting run turns demand into planned orders.
What is manufacturing ERP software?
It is the system of record that holds quoting, engineering, inventory, purchasing, production, quality, and the general ledger on one database. The distinguishing feature against general business ERP is the job: a work order carrying its own bill of material, routing, cost, and quality record from quote through shipment.
Do I need MES if I have ERP?
You need the execution layer, which may or may not be separate software. If your ERP cannot take a clock-on at an operation, a quantity complete, a scrap count, and an inspection result from the machine, then you still need an MES. WorkCell includes shop floor terminals that do this.
Is MRP part of ERP?
Historically yes — ERP grew out of MRP II, and most ERP products include a planning run. WorkCell's MRP run nets demand from sales orders and jobs against on-hand, in-transit and open purchase orders and produces time-phased planned orders a planner releases. Because it reads the same bills, inventory and supplier catalog the rest of the system uses, there is no export into a planning tool and nothing to reconcile afterwards.
Can manufacturing ERP replace QuickBooks?
WorkCell carries a general ledger, accounts payable, accounts receivable, and multi-currency, so it can. Many shops instead keep QuickBooks Online and run it as a live integration, because the accountant already works there. Not built: payroll, fixed assets, budgeting, bank feeds, or revenue recognition.
What does ERP software cost for a small manufacturer?
WorkCell is $995 per month for Core, $2,495 for Professional, and $4,995 for Scale, with Enterprise priced on request and twenty percent off annual terms. Users are unlimited on every plan, so putting a terminal at every machine does not change the invoice.
Does ERP work for high-mix, low-volume job shop work?
That is the case WorkCell is built around. Every job carries its own bill of material revision, routing, and cost, and the scheduler plans against finite machine and labor capacity rather than assuming a repeating master schedule. Shops with one dominant repeat part have easier problems than this.
