How to Set Up Automated Invoicing and Payment Collection for Your Marketing Agency

Automated invoicing removes the manual work of chasing clients for payment. It connects your accounting system to a payment platform so invoices go out, get paid, and reconcile without you touching a spreadsheet or sending a follow-up email.

For agency owners still sending manual invoices and following up by phone or email, this shift saves hours every week and improves how predictably cash lands in the account.

This guide covers how to set payment terms, when to charge a deposit, how to move clients onto a retainer, and how to connect your agency's invoicing to a payment platform like Pinch through Xero or MYOB.

Why Manual Invoicing Costs Agencies Time and Money?

Manual invoicing means someone on your team creates each invoice, emails it, tracks whether it was opened, and follows up when it isn't paid. Every one of those steps takes time away from client work.

The real cost isn't just admin hours. Late payments disrupt cash flow, and cash flow gaps make it harder to pay contractors, run ads on behalf of clients, or plan hiring. Agencies that rely on manual follow-up also tend to have inconsistent payment terms across clients, which makes forecasting revenue difficult.

Automated invoicing fixes this by handling reminders, payment collection, and reconciliation as a standard process rather than a manual one.

What Is Automated Invoicing?

Automated invoicing is a system where invoices are generated, sent, and collected without manual intervention. It typically connects your accounting software (like Xero or MYOB) to a payment platform that charges the client's card or bank account and marks the invoice as paid automatically.

The core components are:

• Recurring billing: invoices generated on a set schedule, such as monthly retainers.
• Automated reminders: clients are prompted to pay before and after the due date.
• Stored payment methods: a client's card or bank account is saved securely so future invoices don't need manual payment each time.
• Automatic reconciliation: paid invoices are matched against your accounting records without manual data entry.

How to Set Payment Terms for a Marketing Agency

Set payment terms before you send the first invoice, not after a client is already late. Most Australian agencies use one of these structures:

• 7 or 14 day terms for project-based work
• Due on receipt for smaller or one-off jobs
• Monthly in advance for retainers, so you're paid before the work is delivered rather than after

Write your terms into every proposal and contract, not just the invoice footer. Clients are far more likely to dispute a due date they didn't agree to upfront than one they signed off on.

If you're moving from informal terms to something firmer, apply the new terms to new clients first, then phase in existing clients over one or two billing cycles with clear notice.

Should I Charge a Deposit as a Marketing Agency?

Yes, for most project work, a deposit reduces your risk and filters out clients who aren't serious. A deposit of 30 to 50 percent upfront is standard for agency projects in Australia, with the balance due on delivery or milestones.

Deposits matter most for:

• New clients with no payment history
• Larger one-off projects like website builds or campaign launches
• Work with high upfront costs, such as paid media spend or contractor fees

For ongoing retainer clients, a deposit is less relevant. Instead, billing in advance each month achieves the same protection, since you're paid before the work is done rather than chasing payment afterwards.

How to Move Clients to a Retainer Model

Retainers give agencies predictable revenue and reduce the invoicing admin that comes with billing project by project. To move a client from project work to a retainer:

• Package the recurring work. Identify what you deliver every month, such as content, ad management, or reporting, and price it as a fixed monthly fee.
• Present the retainer as a value shift, not just a billing change. Frame it around consistent access to your team and predictable output, not administrative convenience.
• Set the billing date in advance. Bill on the 1st of the month for that month's work, rather than in arrears.
• Automate the recurring invoice. Once the retainer is agreed, set it up as a recurring invoice in your accounting software connected to a payment platform, so it generates and collects automatically each cycle.

Recurring retainer payments can be collected automatically each month.

Card vs Direct Debit for Agency Billing

Both methods can be automated, but they suit different situations.

For agencies, a common approach is to use card payments for project deposits and one-off invoices, and direct debit for retainer clients once the relationship is established. This reduces the card processing costs on larger recurring amounts while keeping cards as an easy option for smaller or first-time payments.

What Payment Software Do Marketing Agencies Use?

Most Australian agencies use payment software that connects directly to their accounting system, rather than a standalone invoicing tool. This avoids double handling of invoice data and keeps reconciliation automatic.

Pinch Payments is a payment automation platform built for this purpose. It connects to Xero, MYOB, and QuickBooks, and lets agencies:

• Collect invoice payments by card or direct debit
• Set up automated reminders for unpaid invoices
• Store a client's payment details for recurring retainer billing
• Give clients a self-serve portal to view and pay outstanding invoices
• Reconcile every payment against the matching invoice automatically

See how this works with your existing Xero or MYOB setup.

How to Automate Invoicing for a Marketing Agency in Australia

1. Connect your accounting software. Link Xero, MYOB, or QuickBooks to a payment platform. This lets the platform read invoice data (amount, due date, client details) directly, so you don't create invoices twice.
2. Set your default payment methods. Decide whether clients can pay by card, direct debit, or both, and whether transaction fees are absorbed by the agency or passed on to the client as a surcharge.
3. Turn on Pre-Approvals for retainer clients. This lets you charge an agreed amount automatically on the invoice due date, without the client needing to manually approve each payment.
4. Enable automated reminders. Set reminders to go out before the due date and again if payment is late, so follow-up doesn't rely on someone remembering to send an email.
5. Check invoice notification settings. If you use MYOB or QuickBooks, invoice issued emails need to be switched on in your accounting software for the payment portal link to work correctly. This is a common setup step that's easy to miss.
6. Let reconciliation run automatically. Once a payment is collected, it should be matched against the original invoice and marked as paid in your accounting system without manual entry.

How to Get Clients to Pay On Time

Late payment is usually a process problem, not a client problem. Agencies that get paid on time typically do three things well:

• They bill in advance for retainers, so payment isn't tied to work already delivered.
• They automate reminders, so clients are prompted before a human has to chase them.
• They store a payment method upfront, either a card or a direct debit authority, so the invoice is collected on the due date rather than waiting on the client to log in and pay manually.

A customer payment portal also helps. This gives clients a single place to see everything they owe, update their payment details, and pay in one click, which removes the friction that causes some late payments in the first place.

How to Deal With a Client Who Won't Pay

Start with a direct, specific conversation before escalating. Reference the exact invoice, amount, and due date, and ask when payment will be made rather than sending a generic reminder.

If that doesn't resolve it:

1. Send a formal overdue notice referencing your payment terms and any late fees specified in your contract.
2. Pause further work until the account is current. Continuing to deliver work for an unpaid invoice increases your exposure.
3. Offer a payment plan for clients who are willing but currently unable to pay the full amount, splitting the invoice into smaller scheduled payments.
4. Escalate to formal debt recovery as a last step, using a collections agency or small claims process, if the amount and relationship justify it.

Agencies that automate deposits and use stored payment methods for retainers rarely reach this point, since payment is collected before the risk builds up.
