Financial analysts
You rely on Harvest timesheet data and invoice statuses for reporting, but your email marketing lists only update when someone manually exports contacts, so campaign audience counts are always outdated — this integration means every new client and payment syncs instantly and your records stay current.
Account managers
You need to initiate onboarding sequences the moment a client signs up in Harvest, but you find out about new accounts hours later when checking billing sheets — with this integration, every new client record triggers instant INBOX contact creation so onboarding starts immediately.
📋
Project managers
You answer to stakeholders who want visibility into active client accounts and project sign-offs, but tracking project creation across disconnected apps causes reporting gaps — automating both apps means every project update flows straight into your contact database without manual re-entry.
🔄
Email marketing specialists
The volume of new clients and subscribers is too high for anyone to keep up by hand, leading to missed contacts and delayed autoresponders — connecting these apps means every Harvest client and invoice event populates your INBOX lists automatically.
🤝
Sales representatives
You own the handoff from signed contract to marketing engagement, but depend on manual CSV exports from Harvest to populate your mailing lists — this integration means every new client profile is created in INBOX the second it is registered.
📁
Operations leads
You need a reliable history of all client interactions and billing events, but keep finding gaps between timesheet software and email tools — this integration means every client addition, project setup, and paid invoice is logged reliably across your stack.
