Reduce the hassle of timekeeping and invoicing
Timekeeping and invoicing with Fortes
Stay in control of the time spent on your projects. Simplify time registration for better project planning and more accurate billing.
Easy timekeeping for customer projects
Make timekeeping for billable projects easy, with Fortes Milestones. Project members can book their hours via phone, tablet, or PC. Log hours and expenses in line with project setup, and save time by pre-filling hours in the weekly timesheets so they only need to be confirmed.
And avoid incorrect time entries by shielding non-eligible employees from specific contracts, hour codes and clients. This ensures you're invoicing your customers quickly and correctly, at all times.


Keep track of progress in your portfolio
Make sure your teams are working on the right projects in your portfolio. Track project and operation hours using the timekeeping module in Fortes ProjectFlow.
Project members can log their hours via phone or tablet. Closely integrated with Microsoft 365, Fortes ProjectFlow simplifies timesheet approvals with an automated workflow. Gain insights into actual hours spent on projects and tasks, for a better view of available capacity, leading to better portfolio planning.
Accelerate invoicing for client projects
Streamline your entire invoicing process—from time registration to sending e-invoices. Save time on invoicing, and avoid errors by automating manual steps. Generate customizable invoices quickly and without hassle—even for the most complex contracts.
Integrate invoicing with your accounting software, and create reports and dashboards in Power BI. Fortes Milestones helps you accelerate your order-to-cash cycle by invoicing customers correctly and promptly.


Handle complex contracts correctly
Create separate invoices for different legal entities while centrally logging hours in a single timesheet. Simplify workflows with Fortes Milestones, and automate renewals and indexations of subscription fees.
Combine fees, hours, fixed amounts, and advances into a single invoice. And align subscription billing with customer contracts by applying different rates, end dates and billing frequencies.
