A manufacturing software development company for plants that already run an ERP

Who hires a manufacturing software development company, and what they ask for

In a plant, the request often starts with the person who owns a gap. A production manager wants a screen on each line that shows today's orders. A quality lead wants inspection results that can be searched by lot. A maintenance lead wants a work order a technician can close at the machine, and the plant's IT lead wants all of it connected to the ERP without breaking it. A company that sells software to manufacturers brings the same list, multiplied by every plant that will run its product.

Either way, the work is custom manufacturing software development, and both kinds of buyer get the same team and the same process. What neither gets is a proposal to replace the ERP. It is the system of record, rebuilding it is expensive, and replacing it rarely fixes the gap that prompted the call. The software we write sits beside it, reaches the places it does not, and hands back what it learns.

What we build, and what we leave to the systems you already run

We build four kinds of manufacturing software, and the list is short on purpose. Each one sits where people, materials or machines meet a system that was not designed around them.

Outside those four, a specialist has usually built what a plant needs already. Product lifecycle management, computer-aided manufacturing, enterprise asset management suites, SCADA and historians, lab systems and scheduling come from vendors who specialize in them, and a plant running them is generally right to keep them. Our software reads what those systems hold, and our maintenance tracking works beside a maintenance system or EAM suite the plant already runs, feeding it; where there is none, it covers the basics. The control layer on the equipment belongs to the plant's controls engineers or integrator, who expose its data through a gateway or historian; we read from that, never from the control network itself. It is cheaper to name that boundary on a web page than to discover it during a build.

Our guide to what each system in a plant keeps takes them one at a time.

Where plant software actually breaks

Plant software breaks in the gaps between systems, and a gap shows itself as an everyday question nobody can answer from the records.

Which order did last night's output belong to?

The production order starts in the ERP, is rewritten on a whiteboard, and is keyed into a spreadsheet at shift end, so by morning there are three versions of it. Underneath is a decision nobody made: which system owns the order's status and actual quantities once it is released to the floor.

Is the material the system shows actually on the rack?

The system says it is there, the operator finds it is not, and the floor starts counting by hand. Often consumption is backflushed at standard quantities, so scrap, substitutions and moves nobody recorded never reach the system. The open question is which of them gets captured where it happens.

Which lots did that check cover?

Checks are signed on paper and filed, so when a customer asks about a lot, someone pulls folders one at a time. Quality tracking starts with deciding whether a check is captured at the station or transcribed afterward, and whether each lot records the lots that went into it.

What keeps stopping this machine?

The faults, the fixes and the part behind most of the unplanned downtime sit in one technician's memory until that person leaves, because the work order only ever recorded that a job was closed.

ERP software development services: integration and custom modules

Most of this work is integration with the ERP. We have delivered ERP integrations against SAP, Oracle NetSuite, Odoo and Microsoft Dynamics 365 for clients in other industries. Those were on the business side (orders, inventory and finance), so posting production confirmations, goods movements and scrap would be new work for us. What transfers is a habit: settling which system owns which record before a line of code is written.

The ERP stays the system of record for the item master, bills of materials and routings, production orders, inventory valuation and the financial posting. The software we build collects what happens on the floor: a job started, a quantity produced, a batch rejected, a machine stopped. It is built to post confirmations, goods issues, receipts and scrap back through the ERP's APIs. Where an ERP has no usable API, as on many legacy on-premise installations, the connection runs as a scheduled file exchange, and a failed run alerts a person instead of passing quietly.

Custom modules are the rest of the work. A process unique to your plant is not in any ERP's configuration screens, and bending the ERP around it usually costs more than building the piece beside it.

Changing plant systems without stopping the line

A plant cannot pause for its software, so change arrives in pieces. One line or cell moves first. During the pilot, old and new run side by side, with the old system still posting to the ERP and the new one in shadow until cut-over, compared against the same shift's output. Operators double-enter only for a period their supervisor agrees to. The cut-over itself is planned with you into the plant's own shutdowns and maintenance windows; inside that window the line can still go back, under a back-out plan made for it, and once the window closes, problems are fixed forward.

Inventory is the exception, because lines share stock: a warehouse system cuts over whole, from a physical count, away from month-end close.

Our engineers have done modernization and migration work on software already in live use, in other industries. DevOps runs the environments, releases to floor systems go out through your change approval at times production agrees to, monitoring is running before the first line moves, and the team that planned the move carries it out.

A line that moves cleanly earns the next one. When a line runs into trouble, the next waits until the cause is fixed.

How a manufacturing build runs

Five steps take a manufacturing build from the first call to support after the last line moves. The people who scope the system are the people who build it.

Where a group runs several plants and the work is ongoing, a dedicated team on a fixed monthly fee fits better than a run of fixed-scope projects. We take on manufacturing builds for plants and for manufacturing software companies across the US and Canada, the UK and Europe, the Middle East, and Australia and New Zealand. We keep a daily working overlap with the UK and Europe, the Middle East, Australia and New Zealand, and the US East Coast. For client meetings, we overlap with all of Canada.

The stack for a manufacturing build

The team specializes in each of these, listed against the part of a plant system it serves.

• Supervisor dashboards and office screens — React, Next.js, Angular, TypeScript
• Integration layer and APIs — Node.js, NestJS, Java, .NET, Laravel on PHP
• Production, inventory and quality records — PostgreSQL
• Hosting — AWS
• Line terminals, warehouse handhelds and technician apps — Flutter, React Native

Under every contract, the code and the intellectual property belong to you. The code lives in your repository, and the live system runs in cloud accounts you own. Line terminals and handhelds are built to keep recording through a network or cloud outage and sync when the link returns, and each line gets a written procedure for running while a terminal or the system behind it is down. What is not on that list is hardware. We do not supply, wire or configure PLCs, sensors or the control layer, and the plant supplies terminals, handhelds and floor Wi-Fi to a spec we agree.

Systems we have built, in industries that are not this one

We have not built for a plant, but we have built systems close to several it runs. Field and mobile workforce apps, customer self-service portals, and inventory and stock systems are all delivered work, for clients in other industries.

The core of an inventory system (stock by location and lot, receiving and counts) is the same whether the stock is raw material or not; a plant adds consumption against orders, work in progress, quality holds, unit conversions and lot genealogy. A field workforce app — dispatch, work orders, checklists, photos, working offline — is close to what a maintenance technician carries, once it has the plant's asset hierarchy, spare parts and lockout steps. The ERP integrations above are delivered work, as are CRM integrations with Salesforce, HubSpot, Zoho CRM and Pipedrive.

We have not run this inside a plant, with its shifts and shutdowns. That is why the rollout above is cautious and scoping starts on the floor. Meet the engineers who would work on it. Our page on telecom software makes the same plain disclosure.

What custom manufacturing software costs

The price of a manufacturing build depends on what scoping finds in your plant:

• Systems of record — how many the software must reach, and whether they currently agree with each other.
• The ERP's APIs — whether yours exposes what the job needs, or the connection has to run on scheduled file exchanges.
• How floor data arrives — from a machine that already publishes it, or from an operator at a terminal.
• Sites and lines — one plant behaves differently from six, each with its own version of the process.
• History — how much old inventory, quality or maintenance data has to be migrated and reconciled first.

A band would be easy to publish and useless to you, because these set the number. The first scoping call is free, and the short paid assessment after it measures each of them and ends in a fixed, itemized price, so a part can be cut on purpose rather than discovered missing later. To start, describe what your plant runs and what it cannot see.

Manufacturing software solutions: buy, extend, or build

Buying is right when the process belongs to the vendor, not you. Off-the-shelf manufacturing software solutions cover standard finance, procurement and planning better than anything custom, and where an established MES product fits the plant, it beats a new one on the basics. Extending is right when the platform fits and one gap does not: a module for a process that is yours alone, or a floor-level system the product was never built to reach. Building is right when the workflow is the plant's own, or the software is what you sell.

Scoping settles which fits before anything is quoted, and buying is sometimes the answer. A plant on spreadsheets with a standard process is better served by choosing a product well than by commissioning one.

When the job is a different shape, it is a different service. If the system runs across departments rather than on the floor, our enterprise software development services cover it. Selling one product to many manufacturers, each on its own tenant, calls for custom SaaS development. A first version for real users to try is built as an MVP, and once a system is running, keeping it healthy is the work of our application maintenance services.
