- Choosing an ERP
Lists of the best ERP for medical device manufacturing tend to rank the same large names. They rarely help a plant decide, because the answer depends on things a list cannot see: whether you make finished devices or precision parts for someone who does, whether your products are serialised, which markets you ship to, and whether anyone on your team can run a validation project as well as an ERP project.
This article sets out how to make the decision for your own plant: the types of system on most shortlists, a checklist built around the records a device plant is audited on, demo questions that test a system on your parts, and how plant size changes the answer.
Quick answer
The best ERP for a medical device manufacturer is the one that keeps the batch record the plant is audited on: revision-controlled BOMs and routings, material by supplier lot, measured values with the instrument, held batches with recorded dispositions, outsourced processes followed through return, and a lot-to-unit trace. Plant count, serialisation needs and how much validation work the team can carry decide between an enterprise ERP and a manufacturing-focused one.
What types of ERP do device makers choose between?
Device makers usually end up comparing three kinds of system.
- Large enterprise ERP, such as SAP S/4HANA or Oracle. Broad coverage of finance, supply chain, manufacturing and quality, with batch and serial number management, suited to groups with several sites and an IT and validation team.
- Mid-market and accounting-led ERP. Strong on finance, purchasing and inventory, with manufacturing and quality modules of varying depth. The batch record often lives in a separate tool or on paper.
- Manufacturing-focused ERP with MES. Built around work orders, operations, lots and inspections recorded on the floor. The books normally stay in a separate accounting package.
Some device makers also look at specialist quality management software for document control, CAPA and complaints. That sits alongside the ERP rather than replacing it, and the boundary between the two is worth agreeing early.
ERP selection checklist for medical device manufacturers
Take one real part, with its drawing and inspection plan, and score every shortlisted system against it. For every line, note whether it is standard, needs configuration, needs custom development, or is not possible. In a regulated plant every custom development is also something you will have to validate and keep validated, so count those lines twice.
| Area | What to check | Why it matters |
|---|---|---|
| BOM and revisions | Multi-level BOMs including packaging and labels, with the revision fixed on the batch at release | The batch record must show exactly what the batch was made to |
| Routing and checks | Operations in sequence with the inspection required at each, kept in step with the BOM revision | A missing check on the routing is a missing line on the batch record |
| Production planning | Batches planned on work centres against capacity, with limits such as sterilisation load or cleanroom time respected | Batch size in a device plant is often set by a validated process, not by demand |
| Material traceability | Supplier lot and heat number captured at receipt, issued by lot, traced forward to shipments and back from units | Complaints, recalls and audits are answered from the trace |
| Serialisation | How serial numbers are created, linked to batch and lots, and printed on labels | Some devices need unit-level identity; others do not, and this changes the shortlist |
| Inspection | Nominal and tolerance per characteristic, measured values with the inspector, time and instrument | Results must be traceable to a calibrated instrument |
| Nonconformance and rework | Batch hold on a failed check, disposition with name and reason, rework as an operation with re-inspection | Uncontrolled nonconforming product is a common audit finding |
| Audit trail | User and time on every entry, and what a correction looks like after the fact | An overwritten value with no history will not stand up in an audit |
| Outsourced processes | Vendor operation on the routing, challan out and return in, short returns flagged, vendor cost on the batch | Passivation and sterilisation add lead time and risk outside the plant |
| Validation support | What documentation the vendor provides, and what your team must do to validate the system for its intended use | Validation is the manufacturer's responsibility and takes real effort |
| Integration | Fit with your accounting system and any quality management software, and an API for anything else | The books and the QMS documents often stay where they are |
| Total cost | Subscription or licences, implementation, devices, training, validation effort and internal admin over three years | The licence is often the smallest part of the cost |
Questions to ask in an ERP demo
A prepared demo always runs smoothly. These questions make the vendor work on your products instead.
- Receive a bar lot with its heat number, issue it to a batch, and show me every unit and shipment it reached.
- Record a thread diameter outside tolerance. Show me the hold on the batch, and which role is allowed to lift it.
- Show which instrument took this measurement. If that instrument fails calibration tomorrow, how do I find every batch it touched?
- Correct a count that was entered wrongly. What does the record show afterwards?
- Send a batch to the steriliser on a challan and bring back fewer units than were sent. Where does the difference show?
- Show me the batch record for this batch, as QA would review it.
- Who enters data on the floor, on what device, including inside the cleanroom, and what happens when the network drops?
- What does the system not do today?
The last question matters most. A vendor who answers it plainly, including what it does not claim on validation, is easier to plan with.
How plant size changes the answer
A group with several sites, products sold in many regulated markets, unit-level serialisation and a dedicated IT and validation team may be best served by an enterprise ERP at the core, with an MES or electronic batch record alongside. The comparison of SAP and manufacturing-focused ERP for medical device makers goes into that decision.
A single plant, or a precision parts supplier to device makers, usually has its gaps on the floor: batch records built from paper, inspection values without an instrument, held parts without a recorded decision. A manufacturing-focused ERP with MES built in often covers those with less to configure, and therefore less to validate, while accounting stays in the package the finance team already uses.
A short evaluation plan
- List the records your auditors and customers asked for in the last two audits.
- Decide whether you need unit-level serial numbers, and on which products.
- Shortlist two or three systems of different types and score them on the checklist.
- Run the demo questions on one of your own parts, with its real drawing and inspection plan.
- Ask each vendor what validation documentation they provide and what your team would have to do.
- Compare total cost over three years, including validation and your own team's time.
Where FleekERP fits, and where it does not
FleekERP is a manufacturing ERP and MES for plants that need production execution, inspection records and traceability without an enterprise-scale project. For medical device and precision parts makers it covers material lots linked to finished units, BOMs fixed at release, counts by operation with the operator and time, inspection results against tolerance with the instrument used, batch holds and dispositions, outsourced processes through the challan, and a batch record assembled from floor entries. QC and operators record on Android phones through shop floor apps.
It is not the right choice for every device maker. It is not validated for ISO 13485 or 21 CFR Part 11; it keeps an audit trail with the user and time on each entry, and validating it is your process. It does not keep the books: accounting stays in Tally, Zoho or another system it connects to through the API. The apps need a network connection, there is no barcode or QR scanning, machine data is on the roadmap, and the interface is English. If your products need unit-level serialisation or UDI labels, confirm how that would work before you decide. Put the demo questions above to us exactly as you would to SAP or anyone else.
Frequently asked questions
Is there one best ERP for medical device manufacturing?
No. The best fit keeps the batch record the plant is audited on, at a scale and validation effort the team can carry. Multi-site groups with serialised products often choose an enterprise ERP with an MES; single plants and precision parts suppliers often choose a manufacturing-focused ERP with MES built in.
Why does custom development matter more in a device plant?
Every custom change to a system used for quality records has to be validated by the manufacturer, and validated again when it changes. A system that covers the plant's needs through configuration leaves less to validate and less to maintain.
What should a demo prove for a medical device plant?
That the system can trace a heat number to every unit it reached, hold a batch on an out-of-tolerance value, show which instrument took a measurement, keep the history of a corrected entry, follow a sterilisation return, and produce the batch record QA would review.
Can a device maker keep Tally for accounts and use a separate manufacturing ERP?
Yes. FleekERP runs production, stock by lot, inspection, outsourced processes and dispatch, and syncs purchases, sales, invoices and stock values to Tally or Zoho, so the books stay where they are.
