Can Claude connect to Custom-built software?
Last checked 21 October 2026 by Helm
Yes. Custom-built software doesn't have an official Claude connector yet, but Helm connects it for you, securely and with only the access you approve.
Type: connected by Helm using the method that suits your setup. Needs: a Claude business plan and a Custom-built software account. Coding: none on your side.
What is Custom-built software?
Custom-built software is any system written specifically for your business, from an in-house job tracker to a portal a developer built years ago. It often holds the most valuable data in the business and is usually the hardest to connect to anything new.
Who uses it
Directors
Ask for the numbers they need without waiting on a custom report.
Operations managers
Check status across jobs or orders held in the in-house system.
Admin teams
Have Claude draft paperwork from records that live only in that system.
What your team can ask Claude
“Summarise this week's activity in our job system and flag anything overdue.”
“Which customers in our system haven't had an order in six months?”
“Draft a quote for this customer using the pricing in our system.”
“List records with missing contact details so we can clean them up.”
“Compare this month's numbers with the same month last year.”
What Claude can do with Custom-built software
Read or update, depending on your setup
| Task | Access |
|---|---|
| Answer questions about records in your own system in plain English | Depends on your setup |
| Pull reports your system was never built to produce | Depends on your setup |
| Draft emails, quotes and documents from data held in it | Depends on your setup |
| Spot missing, duplicate or out-of-date records | Depends on your setup |
| Summarise activity for a week, month or job | Depends on your setup |
How it connects
Older and custom systems often have no connector or API. Helm connects them using a method that suits your setup, including a dedicated AI workstation that works inside the software the way your team does, kept apart from everything else and with your approval on each action. We'll recommend the right approach on a 30-minute call.
What you need
- A Claude business plan (Team or Enterprise)
- Admin access to Custom-built software, or someone who has it
- 30 minutes with Helm to agree what Claude can and can't do
Looking after your Custom-built software data
Custom systems often hold everything in one place, so Helm agrees exactly which screens and records Claude can work with before anything is connected.
- Only the access you approve.
- Everything stays in your own accounts.
- On Claude's business plans, your data isn't used to train AI models.
