Trusted by digital and creative agencies
Built for agency workflows
Everything you need to bill clients professionally and track your agency's financial health
Multi-Project Billing
Manage invoices across dozens of clients and projects from a single dashboard. Each client gets their own billing profile with separate payment terms, branding, and financial tracking — so nothing gets mixed up during busy periods.
Retainer Invoicing
Automate recurring invoices for retainer clients with customisable schedules and amounts. Set it once and Invoicemonk handles every billing cycle — freeing your team to focus on client work instead of monthly admin.
Revenue Reporting
Track revenue per client, project profitability, and outstanding payments at a glance. Generate reports that help you make strategic decisions about client retention, pricing, and resource allocation.
Professional Branding
White-label invoices with your agency logo and custom payment terms. Every invoice reinforces your agency's professional identity and builds client confidence in your operations.
How agencies use Invoicemonk
From boutique studios to full-service agencies — here's how Invoicemonk fits your billing model
Monthly Retainers
Set up recurring invoices for every retainer client — SEO, social media management, PPC, or content creation. Invoicemonk sends each invoice automatically on the agreed date. Track retainer revenue separately from project work for clear financial visibility across your entire book of business.
Campaign Projects
For campaign or project work, create milestone-based invoices. Bill 30% at kickoff for strategy and planning, 40% after creative delivery, and 30% on campaign launch. Each invoice details the deliverables completed, making it easy for client procurement to approve payment quickly.
International Accounts
Bill global clients in their local currency without manual conversion headaches. A London client gets an invoice in GBP, a New York client in USD, and a Berlin client in EUR — all from one dashboard. Each invoice is formatted with the correct currency symbol, tax structure, and compliance details.
Common agency challenges — solved
We built Invoicemonk around the real billing problems agencies face at scale
Finance team spends days manually creating and sending monthly retainer invoices
Automated recurring invoices generate and send on schedule for every retainer client. Your finance team reviews them once, then Invoicemonk handles the rest each month.
No visibility into which client accounts are actually profitable
Revenue and expense tracking per client and project. See actual profitability at a glance and make data-driven decisions about pricing and client retention.
Chasing payments across 20+ client accounts is a full-time job
Automatic payment reminders follow up with every client on your customised schedule. Your dashboard shows all outstanding invoices across every account in one view.
Inconsistent invoice formatting undermines professional agency image
Branded invoice templates with your logo, colours, and terms. Every invoice looks polished and professional, reinforcing your agency's positioning with every client interaction.
How it works
From client onboarding to monthly reporting — streamlined for agency operations
Set up client accounts
Create a profile for each client with their billing address, contact person, preferred currency, and payment terms. For retainer clients, configure the recurring invoice schedule. For project clients, define the milestone billing structure. This setup takes minutes per client and ensures consistent, professional billing from day one.
Automate retainer billing
For monthly retainer clients, set the invoice amount, send date, and any standard line items. Invoicemonk generates and sends the invoice automatically each cycle. Your team reviews the queue once a month and can adjust amounts for scope changes before they go out.
Invoice project milestones
For project-based work, create invoices tied to specific deliverables — strategy presentation, creative concepts, campaign launch. Add line items for each component of work and reference the agreed scope. Send the invoice as soon as the milestone is delivered for faster payment.
Track and report
Your dashboard shows revenue by client, outstanding invoices, and payment trends. Pull monthly or quarterly reports to share with partners and stakeholders. Use profitability data to identify accounts that need renegotiation and spots where your agency is leaving money on the table.
Why agencies choose Invoicemonk over alternatives
Enterprise accounting software like QuickBooks or Xero is powerful but overly complex for agencies that primarily need to send professional invoices, manage retainers, and track who has paid. The learning curve alone costs your finance team weeks. Invoicemonk delivers the billing functionality agencies actually use — without the overhead.
Unlike simple invoicing apps, Invoicemonk understands the agency billing model. Retainer clients need automated recurring invoices. Project clients need milestone billing. International clients need multi-currency support. Invoicemonk handles all three from one dashboard, which means your team doesn't need to context-switch between different tools.
Most importantly, Invoicemonk helps you understand your agency's financial health. Revenue-per-client reporting, outstanding invoice tracking, and expense management per project give you the data you need to make confident business decisions — like which accounts to grow, which to renegotiate, and when to hire.

"We manage 30+ retainer clients. Invoicemonk's recurring invoices save us hours every month. Before, our finance manager spent two full days sending monthly invoices. Now it's completely automated and clients pay faster because of the reminders."
Kate B.
Operations Manager, Digital Agency
"The multi-currency support is a game changer for our international client base. We have clients in five countries and each gets invoices in their local currency. It makes our agency look polished and removes friction from the payment process."
David L.

"Project profitability tracking has changed how we run our agency. We discovered two accounts were actually unprofitable once we factored in all the costs. Now we use Invoicemonk data to negotiate better rates at renewal time."
