Custom Application AI Integration
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.
Why It Matters
Not a template, an integration built around what you actually have. Off-the-shelf connectors assume a standard system on the other end.
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.
Rather than relying on documentation that may be outdated or missing entirely, we observe the application's real behaviour, its data structures and its access points directly.
Two systems built years apart almost never use the same field names or codes for the same thing. The matching considers what a field actually represents, using several signals together, so it can bridge naming differences that a simple lookup table never would.
An API is the ideal route, but not every custom application has one. Where it does not, we build against a database connection, a file export routine, or a lightweight interface layer designed specifically for that system, so the absence of an API is not a dead end.
Older internal systems built years ago, still running a process nobody has replaced.
Proprietary output logs and data feeds from production or lab equipment.
Customer or vendor portals built specifically for your business, connected to your ERP.
Specialist tools common in your industry that have no mainstream ERP connector.
Bridging two bespoke applications that currently exchange data manually or not at all.
Turning an existing file export or import routine into a reliable automated flow.
We study your application's actual behaviour, data structure and access points directly.
We agree what should move between the two systems, and in which direction.
We build the matching and extraction logic that bridges the two systems' structures.
We test against real records from both systems before anything runs live.
The connection runs live with a review path for flagged cases, refined over time.
Manual data transfer between systems
Mapping across mismatched structures
Uncertain matches, not guessed
Life for a system worth keeping
Data reaching your ERP
Behaviour, often for the first time
We build ERP systems, so the integration respects how your ERP actually validates data.
We map real behaviour directly rather than relying on documentation that may not exist.
Uncertain mappings are shown for confirmation, not silently resolved and risked.
The integration is proven against real records from both systems before going live.
We choose the approach that fits your data and hosting rules, with no lock-in.
Any internal tool, legacy system or bespoke software your business runs that does not have an off-the-shelf connector to your ERP, such as an old order-entry tool, a proprietary machine controller, or an internally built portal.
Ideally yes, but not always. If it has an API or a database we can query, that is the fastest route. If it does not, we assess other options such as a file-based exchange or a lightweight interface layer built specifically for the connection.
AI handles the translation work that a fixed mapping cannot: interpreting free-text fields, matching records that are named differently in each system, and flagging data that does not clearly map across, so a person confirms it instead of a wrong guess being posted.
Yes. The same approach works for connecting any two systems, whether one of them is your ERP or both are bespoke applications that currently do not talk to each other at all.
We start by mapping the application's actual behaviour and data structure directly, since documentation is often missing or outdated for older custom systems. This adds time upfront but avoids building on wrong assumptions.
It varies more than for standard platforms, since every custom application is different. A first working connection typically takes six to ten weeks, and we scope this properly before committing to a timeline.
