📈
Finance Directors
You're reviewing billing logs across multiple platforms but your reports only update when someone manually exports invoices, so the revenue counts you're tracking against are always a few hours behind — with this integration, every paid invoice triggers an email instantly and your financial data stays current.
Project Managers
You're overseeing client deliverables but find out about project delays after it's too late to adjust schedules, so client satisfaction suffers from poor communication — this integration means every project update automatically dispatches timely emails to keep all stakeholders aligned.
🤝
Agency Owners
You answer to demanding clients who expect immediate updates on billable hours and invoice statuses, but manual status checks create severe bottlenecks — automating both apps means every timesheet entry and invoice event triggers instant client notifications without manual effort.
📊
Operations Leads
The volume of timesheet entries and client invoices is too high for anyone to keep up by hand, leading to missed billing notifications and frustrated clients — connecting these apps means every transaction automatically sends reliable emails across your entire client base.
👥
Account Managers
You own the client relationship and depend on someone upstream to hand over billing details before you can follow up, causing awkward delays — this integration means every new invoice or client record immediately dispatches the necessary follow-up email.
🗂️
Business Analysts
You need a reliable history of billing events and client communications, but keep finding gaps in your audit logs due to manual oversight — automating both apps means every Harvest action securely dispatches and logs corresponding SMTP emails without omissions.
