📈
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.
