Manufacturing Software Development Company for Plants Under 500 People
Your ERP covers 80% of the plant, and the other 20% runs on spreadsheets, whiteboards and email. Vascoh builds custom manufacturing software that fills that gap and connects to the systems you already own.

Source: National Association of Manufacturers, Facts About Manufacturing (2026)What does a manufacturing software development company build?
For a small plant, the work is rarely a new ERP. It is the tool the ERP lacks: a tablet app for operators to log downtime, a portal for customers to check order status, a quoting calculator that matches how your estimators think, or a service that turns EDI 850 purchase orders into sales orders automatically.
The National Association of Manufacturers reports that 93.1% of U.S. manufacturing firms have fewer than 100 employees. Software built for that size has to be cheap to run, quick to learn and tolerant of messy data.
Examples of what this looks like in practice: a machine shop that tracks every job traveler on paper can get a tablet app where operators scan a work order barcode, start and stop operations, and record scrap with a reason code. Those scans post to the ERP as labor and quantity transactions, and the office sees job status without walking the floor.
- Shop floor apps for work order status, scrap, downtime and labor capture
- EDI 850, 855, 856 and 810 handling connected to the ERP
- Customer and supplier portals with order, shipment and certificate access
- Quoting and costing tools tied to BOM and routing data
- Dashboards that join ERP, machine and quality data
Why do plants still run on spreadsheets?
The Manufacturing Leadership Council found that 70% of manufacturers still collect data manually. Spreadsheets win because they take an afternoon to build and nobody has to ask IT. They lose when two people edit the same file, when a formula breaks silently, or when the one person who understands the workbook leaves.
Replacing a spreadsheet with a small web app usually keeps the same screens and columns the team already knows, adds validation and user roles, and writes to a real database. The goal is the same workflow with fewer failure points.
Build custom, buy a package, or configure the ERP?
Configure first. If the ERP's own modules or a marketplace add-on cover the need, use them. Buy a package when the problem is common, such as barcode scanning or shipping labels. Build custom when the workflow is part of how you win business: a unique quoting method, a customer-specific compliance step, or a scheduling rule that no package supports.
A useful test is to list what the process needs, then mark each need as met, partially met or missing in the packaged option. If the missing items are the ones that matter to customers, custom build is justified.
Custom does not have to mean a large project. Many useful tools are a single screen backed by a database and two API calls. Starting with one narrow tool lets the plant judge the working relationship and the result before committing to anything larger.
How does custom software connect to an existing ERP?
Through the interfaces the ERP offers. Epicor Kinetic, Acumatica, NetSuite and Business Central have REST APIs. Older systems may offer SOAP, ODBC, database views or file drops. Vascoh picks the most stable option, builds a thin integration layer with retry handling and logging, and keeps business rules in your code rather than inside ERP customizations that break on upgrade.
For plants that cannot find enough skilled people, a point the NAM raises with 1.9 million projected unfilled manufacturing jobs through 2033, software that removes re-keying frees scarce staff for work that needs them.
Authentication deserves attention too. Plant tools should use single sign-on with your existing identity provider where possible, role-based access for operators versus supervisors, and an audit trail for every change to a quantity or a status.
Who owns the code and who maintains it?
You should receive the source repository, deployment scripts and documentation. Hosting can be in your own cloud account so you control access and backups. Agree up front on how updates, bug fixes and ERP version upgrades are handled, and require tests around the integration points since those are where upgrades cause breakage.
How a project runs
From first call to working system.
Scope the gap
Walk the process with the people who do it, list the manual steps, and pick the one that costs the most hours or causes the most errors.
Build in small releases
Vascoh ships a working first version against your ERP, with real data, so operators can use it and correct the design early.
Hand over
You get the repository, documentation and a monitored deployment. Support terms are agreed in writing before launch.
Questions
Common questions
What does a manufacturing software development company do?
It designs and builds software around a plant's processes: shop floor apps, ERP extensions, integrations, EDI, portals and reporting. The work usually connects to an existing ERP rather than replacing it.
How much does custom manufacturing software cost?
It depends on scope, integrations and data quality, so any honest figure needs a scoping conversation. A single-purpose tool connected to one ERP is a very different project from a multi-site system.
Can custom software work with my old ERP?
Usually yes. Even legacy systems often offer ODBC access, database views, flat file exports or a SOAP interface. The integration layer can use whichever is most stable.
Should I build or buy manufacturing software?
Buy for common problems like barcode scanning. Build when the workflow is specific to how you quote, schedule or satisfy a customer and no package fits without heavy workarounds.
Who owns the source code?
It should be you. Agree on repository ownership, hosting account and documentation in the contract before work starts.
