The Problem
Why agency billing breaks generic invoicing tools
A freelancer usually bills one client at a time, the same way every time. An agency doesn't get that luxury. In a single month, your team might send a retainer invoice on the 1st, a project invoice when a campaign wraps mid-month, and a rush invoice for scope added outside the original agreement, often to a dozen clients at once, in more than one currency. Most invoicing tools are built around the freelancer's version of billing: one client, one invoice type, one currency. Stretch that across an agency's client list and the cracks show up fast.
Account managers recreate the same client details in every new invoice, and small errors — a wrong contact, an outdated address — slip through more often than anyone would like.
Retainer invoices get sent late, or forgotten entirely, because nothing in the system triggers them automatically.
Finance can't answer a simple question — which clients are current and which are overdue — without opening a spreadsheet and cross-referencing three different tools.
International clients get invoiced in the wrong currency, which stalls approval on their end and delays payment by days or weeks.
None of this is a people problem. It's a tooling mismatch. Agencies need billing software built around how agencies actually invoice, not a scaled-up version of a freelancer's single-client workflow.
What Alfaa Handles
Built for how agencies actually bill
Retainer billing that runs itself
Set the amount, the client, and the schedule once, and Alfaa generates and sends the invoice automatically every billing cycle. Retainer clients get billed on the same date every month without anyone on your team remembering to do it manually.
One workspace for every client
Save each client's billing details once, then reuse them across every invoice, retainer or project-based. As your roster grows from five clients to fifty, billing stays organized in one place instead of scattered across shared drives and old email threads.
Project invoices exactly when work closes
Not every engagement fits a retainer. Raise a one-off invoice the moment a campaign, deliverable, or milestone wraps, completely separate from your retainer schedule, so project work never gets tangled up with recurring billing.
Correct currency, every client
Invoice each client in their own currency with the right formatting for their region. A New York client gets billed in USD, a London client in GBP, from the same dashboard, without a separate tool or manual conversion.
Invoices that look like they came from your agency
Send through Gmail, Google Workspace, or a custom domain, so clients see your agency's name and address in their inbox. A generic "noreply@invoicingtool.com" sender undercuts the professional image you've built with the client.
One dashboard for where every client stands
See invoices raised, payments received, and what's still outstanding across your entire client list without opening a spreadsheet or pinging finance for a status update.
How It Works
How agencies actually use Alfaa
Setting up a new retainer client
Add the client once, with billing details and contact info. Set the retainer amount and the date it should go out each month. From that point, the invoice generates and sends itself, and you'll see it land in the dashboard as "sent" without touching it again.
Closing out a project
When a campaign or deliverable wraps, create a one-off invoice for that specific scope of work. It's tracked separately from any retainer invoices for the same client, so your billing history stays accurate even when a client is on both a retainer and a project at once.
Checking where things stand before a client call
Open the dashboard, filter by client, and see the full billing history, what's been paid, what's pending, and what's overdue, in the minute before a status call instead of digging through email.
Switching to Alfaa
Switching from a general invoicing tool or spreadsheets
Agencies usually land on Alfaa in one of two ways: they've outgrown a freelancer-focused tool like a basic invoice generator that can't automate retainers, or they're moving off manual invoicing in Google Sheets or Word templates that break down once the client list passes a handful of accounts.
Coming from a freelancer tool, the biggest shift is automation. Retainer clients stop requiring a manual invoice every month, and multi-currency billing stops being a workaround. Coming from spreadsheets, the shift is visibility. Instead of a shared sheet that's only as accurate as the last person who updated it, every invoice and payment status lives in one system everyone on the team can check.

Frequently asked questions
Everything you need to know about invoicing for marketing agencies
Software that handles retainer billing, project invoices, and multiple clients from one dashboard. Alfaa covers all three.
Yes. Alfaa supports recurring retainers, project-based invoices, and multi-currency billing for international clients.
No. Alfaa handles invoicing and billing, not bookkeeping. Most agencies run it alongside their accounting software or hand invoice records to a bookkeeper.
Most bill a fixed amount on a fixed schedule, typically monthly. Alfaa automates the sending so it stops depending on someone remembering to do it.
Agencies typically bill several clients at once, on different schedules, mixing retainers and project work. Freelance tools are usually built around one client and one invoice type, which is why agencies tend to outgrow them.
Yes. Retainer clients bill automatically on schedule, while project clients get invoiced manually whenever a deliverable closes. Both live in the same client workspace.
It usually delays approval on their end, since finance teams often can't process an invoice outside their standard currency workflow. Setting the correct currency per client avoids this.
Most agencies do. Alfaa handles the client-facing billing workflow; a separate accounting platform or bookkeeper handles ledgers and financial reporting.
