Effi is your back-office admin — without the salary

One billing workspace for your whole agency

Effi works in the background catching overdue invoices, chasing receipts, and flagging unbilled work — so your team spends billable hours on clients, not on admin that doesn't pay.

  • No credit card
  • EU-hosted data & AI
  • ZUGFeRD-ready
  • Multi-client billing
  • Team workspace access
  • Custom branding on invoices
  • Overdue alerts & reminders
  • Receipt OCR for expenses

Agency billing breaks in all the wrong places — and it costs you.

Every invoice that slips through costs real money. Every hour your team spends chasing billing admin is an hour they're not billing clients.

One missed overdue invoice across 10 clients can wreck a month's cash flow

Effi watches every client in your workspace simultaneously. Overdue invoices, unbilled project hours, and missing receipts surface before they become a cash flow problem.

Account managers spend billable time doing billing admin instead

When your team can't access invoices, they interrupt finance — or worse, leave it. Add them to the workspace with the right permissions. Everyone sees what they need.

Unclaimed client expenses are money your agency absorbed instead of billed

Travel, tools, subscriptions charged to a project — if they're not logged, they come out of your margin. Team members photograph receipts; OCR logs them in seconds.

What Agencies use most

Invoices, expenses, and Effi's Action Center — connected in one workspace.

Team Workspace

Everyone in one billing workspace

Invite account managers, finance, and ops. Role-based access means the right people see the right things — and only approvers can trigger sends.

Clients & Projects

Every client, every project — one thread

Save client details once. Track work against named projects. Invoice directly from a project — no copy-pasting between tools.

Action Center

Effi watches every client for you

Overdue invoices, stale drafts, and unbilled project hours across your whole agency surface in one place. Effi drafts the next action — you approve.

Invoices

Professional invoices with your branding

Your logo, your colours, your invoice number format. PDF, email, and ZUGFeRD e-invoice ready. Recurring billing for retainer clients.

Questions from agency teams

Straight answers about what Effitrio does for agencies. Full FAQ →

How many team members can access the workspace?
The free tier supports a single user workspace. Pro unlocks team access — invite as many members as your agency needs with role-based permissions.
Can we bill clients in different currencies?
Yes. Each invoice can be set to a different currency. Client records store their default currency so billing is consistent.
Does Effi work across all our clients at once?
Yes. Effi watches your entire workspace — not just one client. Overdue invoices, unbilled hours, and missing receipts across every client surface in the Action Center together.
Can we set up retainer billing for monthly clients?
Yes. Create a recurring invoice once — client, amount, cycle — and Effitrio generates it on schedule. You approve before each one sends.
Is client data kept private between workspace members?
All workspace data is shared within the workspace and isolated from other workspaces entirely. Database and AI both run on EU servers.
