No Off-the-Shelf Connector for Your App? We Build One
Every business ends up with at least one system that nobody makes a connector for: an old order-entry tool, a machine controller, an internal portal built years ago. We connect it to your ERP directly, with AI handling the translation a fixed mapping cannot, such as free-text fields and records that are named differently on each side, flagging anything it cannot confidently map.
50+ ERP and software projects. Zero failed projects since 2021.
The app that never got a connector is still running your business
A system too custom for a marketplace plugin is often too important to keep working around by hand.
Not a template, an integration built around what you actually have
Off-the-shelf connectors assume a standard system on the other end. A bespoke application rarely matches that assumption, so the integration is built by mapping your application's actual behaviour and data structure directly, not by adapting a generic template to fit.
- Built around your application's real structure and behaviour.
- No assumption that it matches a standard system.
- Works even where documentation is missing or outdated.
Where a fixed mapping breaks, AI still finds the match
Two systems built years apart rarely name things the same way. AI matches records by meaning rather than exact text, handles free-text fields a rigid mapping cannot parse, and flags anything it is not confident about instead of posting a wrong guess.
- Matching by meaning, not just exact field names.
- Free-text fields interpreted, not just rejected.
- Low-confidence mappings flagged for a person to confirm.
What a working custom integration looks like
Your application, the AI layer doing the translation, and your ERP on the other end.
From an isolated system to a connected one
The kinds of custom systems we connect most often
If it holds business data and has no existing connector, it is likely a fit for this.
Legacy in-house tools
Older internal systems built years ago, still running a process nobody has replaced.
Machine and equipment controllers
Proprietary output logs and data feeds from production or lab equipment.
Bespoke portals
Customer or vendor portals built specifically for your business, connected to your ERP.
Industry-specific software
Specialist tools common in your industry that have no mainstream ERP connector.
Two custom systems, connected
Bridging two bespoke applications that currently exchange data manually or not at all.
File-based exchanges
Turning an existing file export or import routine into a reliable automated flow.
What connecting a custom application changes

Custom application AI integration questions
What counts as a custom application here?
Does the custom application need an existing API?
Where does AI fit into a custom integration?
Can this connect two custom applications to each other, not just to an ERP?
How do you handle an application with poor or no documentation?
How long does a first integration take?
There is no such thing as too custom to connect
A system without a marketplace connector is not a dead end, it is just a system nobody has mapped properly yet. The absence of a plugin says nothing about whether the connection is possible.
Mapping the application directly, building the AI layer that handles the translation, and flagging what it cannot confidently resolve, is how a system that has run in isolation for years finally joins the rest of your business data.
