How We Help

Based in Gippsland, Victoria, Clever Ops understands the tools Australian Professional Services and Education businesses depend on. We connect Basecamp to Mailchimp with purpose-built integrations that handle projects and to-dos sync reliably at scale. On the technical side, Basecamp uses a REST API with OAuth authentication, and Mailchimp authenticates via API key, which our team handles as part of the build.

Scalable Without Extra Headcount

As your data volume grows, the integration scales with you. No need to hire additional admin staff to keep Basecamp and Mailchimp in sync, even as your business doubles.

Custom-Built for Your Workflow

Unlike generic connectors, we build integrations tailored to how your business actually uses Basecamp and Mailchimp. Custom field mappings, business rules, and error handling included.

Amplify Basecamp Strengths

Built-In Error Handling and Alerts

Our integrations include automatic retries, error queuing, and real-time notifications. If something fails between Basecamp and Mailchimp, your team knows immediately and the system self-recovers where possible.
