What is Legacy desktop software?
Legacy desktop software is the older program installed on your computers that the business still runs on, often without a modern online version. It's common in accounting, wholesale, manufacturing and property businesses that have used the same system for years.
Who uses it
Office managers
Get answers from the old system without clicking through screen after screen.
Accounts teams
Pull figures out of the desktop program for reports and reconciliations.
Directors
See what's happening in the business without learning an outdated interface.
What your team can ask Claude
“Pull today's orders from our desktop system and summarise them by customer.”
“Which accounts in the old system have been inactive for a year?”
“Copy these job details from our desktop software into a client summary.”
“List entries from last week that are missing a reference number.”
“Summarise the month's sales recorded in our desktop program.”
What Claude can do with Legacy desktop software
Read or update, depending on your setup
| Task | Access |
|---|---|
| Look up and summarise records held in the desktop program | Depends on your setup |
| Produce reports the software can't easily export | Depends on your setup |
| Move information between the old system and newer tools | Depends on your setup |
| Draft documents and emails from data in the program | Depends on your setup |
| Check entries for gaps or errors | 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 Legacy desktop software, or someone who has it
- 30 minutes with Helm to agree what Claude can and can't do
Looking after your Legacy desktop software data
Older systems rarely have fine-grained permissions, so Helm sets up a dedicated, limited environment and agrees exactly what Claude may look at and change.
- 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.
