Performance analysts
You're tracking billable hours and revenue metrics in Harvest, but your CRM reports only update when someone manually exports client records, so the revenue counts you're reviewing are always outdated — this integration means every new client lands in Sellsy instantly and your analytics stay current.
Sales representatives
You need to act fast on new client signups and billable project updates, but you find out about closed deals hours later because timesheet records live in a separate system — automating both apps means every Sellsy contact and Harvest project syncs immediately so you can follow up without delay.
📋
Project managers
You answer to clients and stakeholders who want to see immediate progress on billable hours and project tasks, but tracking updates require manual cross-referencing between platforms — connecting these apps means every project task and client entry flows smoothly across your workspace.
💼
Billing coordinators
The volume of new invoices and client additions is too high for anyone to keep up by hand, leading to missing payment records and mismatched customer profiles — this integration means every paid invoice and client record updates automatically without manual data entry.
🔄
Operations leads
You own the onboarding workflow and depend on sales teams to hand over new client details from Sellsy into Harvest, but manual handoffs frequently cause dropped tasks — automating both apps means every new lead or project transitions smoothly to the next team member.
🗂️
Compliance officers
You need a reliable audit history of every billable task and customer interaction, but manual record-keeping keeps leaving gaps in your compliance logs — integrating these apps means every activity is logged accurately and consistently across both systems.
