Sage 50 runs on a desktop computer in the office, so most CRMs can't reach it. That leaves someone typing the same customer details into two systems. For a UK product business on FoundationsAI, we set up a sync that copies customer records from Sage 50 into their CRM every hour, so Sage stays the one place they update.
What comes across
- Customer name and company
- Address, including town, county and postcode
- Contact name, phone and email
- The Sage account reference, saved on the contact
- A "Sage" tag, so synced customers are easy to find
How it works
- Sage to CRM only. Nothing in Sage is changed
- It matches existing contacts by email first, then phone, and fills in missing details without making duplicates or overwriting what's there
- It runs every hour while the office computer is on
- If anything fails, we get an alert with the error and fix it
How it's set up
We add a separate Sage user that can only read customer records, nothing else. A small script on the office computer logs in as that user and sends new or changed customers to FoundationsAI, where an automation files them. Setup took under an hour on a video call.
What it doesn't do (yet)
It doesn't send anything back to Sage, and it doesn't copy invoices or orders. It needs the computer with Sage on it to be switched on. If you use Sage Accounting (the online version) rather than Sage 50, ask us, as that connects differently.
The result
One place to update customer details, and every Sage customer ready for follow-up, reminders and email campaigns in FoundationsAI.
Common questions
Does it work with Sage 50 Accounts?
Yes, it's built for the desktop version of Sage 50.
Is my Sage data safe?
The sync uses its own read-only Sage user that can only see customers. It can't change anything in Sage.
How much does it cost?
It's included on Managed. On Pro it takes about an hour to set up, so we can do it as part of your free 5-hour setup session.
Which plan do I need?
Pro or Managed, because the sync uses an automation to file each customer.
