Financial Analysts
You report on billable hours and revenue and decide from it, but the numbers are always stale because timesheets and invoices live in separate systems — connecting these apps means every invoice and time entry syncs instantly and your reports reflect real-time data.
⚡
Project Managers
You need to act fast on project approvals and billable tasks, and you find out too late when client payments stall — automating both apps means client updates and invoice statuses land in your workflow immediately so you can take action without delay.
📋
Account Executives
You answer to a client or an outside party who wants to see progress and itemised hours, but updating invoices by hand creates frustrating delays — with this integration, every Harvest timesheet and invoice transitions smoothly into Invoice Ninja without manual copying.
📊
Operations Leads
The volume of time entries and client invoices is too high for anyone to keep up by hand, leading to missed billable hours — integrating these apps means high-volume data moves seamlessly between systems so nothing gets left behind.
🤝
Billing Specialists
You own the next step of sending client invoices and depend on someone upstream to hand over accurate project data — this integration means completed Harvest projects and invoices pass directly to Invoice Ninja so your billing cycle never stalls.
🗂️
Agency Owners
You need a reliable financial history and keep finding gaps between tracked time and billed amounts — automating both apps means every client record, invoice, and payment aligns perfectly across platforms.
