Overview
Candango is a product we designed and built ourselves: a multi-tenant sales CRM that keeps a sales team's entire workflow in one place.
Instead of running the pipeline in one app, email in another, the calendar in a third, and accounting somewhere else, Candango brings deals, contacts, activities, email, calendar, and invoicing together in a single workspace.
One place to run sales—no manual logging, no jumping between tools.
Everything in One Place
Teams manage deals across multiple custom pipelines on a drag-and-drop board. Every deal carries its own timeline—notes, activities, emails, and meetings—so the full history of a sale lives in a single view.
Contacts, companies, and activities are all connected, with a built-in email client and calendar screen so reps never have to leave the CRM to get their work done.

The deal pipeline — drag deals across customizable stages.
Integrations
Candango is built around the tools sales teams already use, syncing them automatically so information is captured without anyone typing it in.
Google — email & calendar. Each salesperson connects their own Google account. Gmail is captured and matched to the right person and deal automatically, and a built-in composer sends rich-text emails with attachments straight from a deal. Google Calendar stays in two-way sync, so meetings booked in Candango or in Google always match.
QuickBooks — estimates & invoices. When a tenant connects QuickBooks Online, deals map to QuickBooks customers, estimates are created on the deal and price it automatically, and won work converts selected estimates into a single invoice—each document viewable as the real QuickBooks PDF and sent through the same email composer.
