Every billing structure, one platform.
Day-rates, project milestones, retainers, and expense reimbursements — Feen handles every way a consultant bills, across Belgian and international clients, with Peppol compliance built in from day one.
The billing complexity consultants face every day
Consultants and freelancers juggle day-rates, project milestones, retainers, and expense reimbursements across multiple clients simultaneously. Add international B2B invoicing, Belgium's 2026 Peppol mandate, and the ever-present VAT obligations, and admin becomes a serious drain on billable hours.
Day-rates, retainers, and milestones
Whether you bill daily, weekly, or on project milestones, Feen handles all billing structures on the same platform. Split complex projects into phase invoices, track retainer balances, and reconcile expenses without switching tools.
International clients and Peppol B2B
Consultants frequently invoice EU businesses, multinationals, and public-sector clients — many of whom now require Peppol-compliant e-invoices. Feen sends Peppol invoices directly and handles EU VAT rules automatically.
Expense tracking and reimbursements
Travel, hotels, materials, subcontractors — expenses are billed back to clients and must be documented for VAT. Feen's OCR engine extracts data from receipts instantly so every cost is captured before you submit.
Professional invoicing for consultants and freelancers
