Most small businesses keep client data in three or four places. A CRM like HubSpot, Salesforce, Pipedrive or Zoho. Accounting in Xero or MYOB. Then your industry system: loan origination for brokers, practice management for law firms and accountants, rostering for NDIS providers, property management for agencies.
CRM integration gets those systems to agree. When a contact, deal or invoice changes in one place, the change lands in the right field everywhere else.
Connecting two apps is the easy bit. The harder part is deciding which system wins when they disagree, catching duplicates, and knowing a sync failed before your team does. That's what the rest of this page covers.
If a native connector already does what you need, use it. We get called in when it can't handle your fields, your rules or a third system in the chain.
