Client Invoicing: 7 Proven Tips to Get Paid Faster in 2025

Nothing sends your anxiety to the roof faster than multiple past-due client invoices. 

After all, who’d want to chase invoices? Dealing with multiple missed client payments can be pretty stressful. Like barely-getting-enough-sleep type of stress, with constant worries about clients ghosting you or issuing severely delayed payments. 

We feel you. As someone who takes pride in your agency’s work, the last thing you want is to completely miss payroll because of clients who can’t pay on time. 

This is why we’ve compiled the best actionable invoicing tips from agency owners who went through the horrors and returned wiser.

Whether you’re issuing an invoice for the first time or streamlining your process after dealing with late payments recently, this guide is for you. 

You’ll learn tried-and-tested strategies from industry veterans so you can focus on delivering excellent outputs without getting bogged down by unpaid invoices. 

But first, let’s talk about the basics…

Why Client Invoicing Should Be Priority Number One.

An invoice is a document detailing the services rendered and the terms of payment the client must follow. It represents the money that should come in for creative agencies; without this cash flow, the business will be in big trouble.

Sadly, agencies are rife with horror stories involving delayed client payments. A 2022 Late Payments Report reveals design agencies often have to contend with this inconvenience, with 50% of their invoices getting paid up to 60 days (or more) too late.

Dealing with late payments means agencies must spend up to 13 hours per week following up, stealing precious time they could have spent sharpening their sales strategies, training new hires, finding new clients, or raising investments. 

Which brings us to these golden rules on client invoicing (and getting paid on time): 

How To Invoice Clients: 7 Steps To Get Paid on Time, Every Time

Sending an invoice is one thing, but it takes excellent planning to ensure your clients won’t make any excuse to delay payment for as long as they want. 

Here are seven tips you can apply right away to get your invoices paid on time and safeguard your agency’s finances: 

1. Draw Up a Contract

Letting your clients dictate when you’ll get paid immediately puts you on a losing end. 

A contract ensures a win-win situation for both parties before the project officially begins. 

A well-structured contract sets the foundation for your business relationship and protects you from potential payment delays and disputes. 

Negotiations can happen before a contract is finalized. Once it’s signed, however, every communication after that will simply reinforce what’s already in the document. 

Here's how you can create a contract that covers all your bases:

a. Set Clear Expectations Upfront

• Discuss Payment Terms Early: During the initial consultation or contract negotiation, discuss your rates, payment terms, and deadlines. This will help avoid confusion and potential conflicts down the road.
• Establish a Clear Understanding of the Project Scope: Ensure you and your client are on the same page regarding the scope of work and payment expectations. This includes setting clear guidelines for what happens in case of scope creep—where the project expands beyond the original agreement.

b. Define Payment Terms

• Payment Periods: Communicate your payment period to clients when agreeing on a contract. Typical payment terms vary by region, such as 30 days in the UK, 14 days in some EU countries, and up to 60 days in the U.S.
• Payment Methods: Specify the accepted payment methods (e.g., credit cards, Apple Pay). If you offer recurring payments or installment plans, clearly outline these options.
• Payment Due Dates: Set specific and communicated due dates for your invoices to avoid ambiguity.
• Late Payments & Fees: Outline the consequences of late payments, such as additional fees or interest charges. Make sure your client clearly states and understands these.

c. Incorporate a Payment Schedule

• Upfront Payments: Consider requiring an upfront payment, such as a 50% retainer, especially for larger projects. This not only secures your time but also ensures the client is committed.
• Milestone Payments: For ongoing projects, set up milestone payments tied to specific deliverables. This helps maintain cash flow and reduces the risk of non-payment.

d. Address Scope Creep

Scope creep happens when the project requirements exceed the original project scope. Here’s how your agency can deal with it: 

• Include terms for scope creep in your contract. By doing so, your agency won’t be forced to turn into a charity to complete work outside a pre-set project scope. 
• One way to address scope creep in your contract is to use a core/flex model. In this model, you sell core services at a fixed, outcome-based price and bill additional services hourly. 
• If scope creep occurs, politely highlight it to the client during weekly calls or emails and reflect the additional cost in your invoice.

e. Get Client Agreement

• Clarify Terms and Conditions: Be prepared for some negotiation, but it's better to settle all terms and conditions upfront rather than deal with issues later.
• Contract Signatures: Ensure your client signs the contract electronically or in person. This formalizes the agreement and makes it easier to enforce terms.

2. Ask for Payment Upfront

Upfront payments are built on trust, but the scale is tipped in your favor this time. 

This type of advanced payment requires clients to pay the invoice before the project starts. 

Charging clients upfront secures the agency’s cash flow and ensures clients are committed to the project. 

Here’s how to implement an upfront payment process that works:

a. Adopt an Upfront Billing Model

• 100% Upfront for Small Scopes: Small projects or new clients require full payment before starting the work. This is particularly useful when the project scope is clear and manageable.
• 50/50 Split for Medium Projects: For projects under $10,000 or short-term engagements, consider splitting the payment into two parts: 50% upfront and 50% upon completion. This keeps the client invested while ensuring you’re compensated for your efforts.
• Installments for Larger Projects: For more extensive, long-term projects, set up a payment schedule with installments tied to project milestones. The first payment should always be due before you schedule the start of the project.

b. Set Milestone Payments

• Link Payments to Deliverables: For project-based work, align payments with specific project milestones. This ensures you’re regularly compensated as the project progresses and reduces the risk of unpaid invoices.
• Final Payment Before Asset Delivery: Make it clear in your contract that final assets will only be delivered once the final payment is made. This gives clients a strong incentive to pay promptly.

c. Handle Exceptions Cautiously

While most clients should adhere to your upfront payment terms, enterprise and government clients may require different arrangements, such as net 30 or net 90 payment terms. These clients are usually reliable, but setting expectations and monitoring payments closely is important.

d. Enforce Strict Payment Policies

• No Tolerance for Delayed Payments: For new clients or those with whom you have yet to establish trust, it’s crucial to enforce your payment policies strictly. If a client is late with a payment after one or two reminders, consider pausing work until the account is settled.
• Secure Payments Before Work Begins: Never start prepping or working on a project until the invoice is paid, especially for new clients. This prevents situations where clients delay payment or, worse, avoid paying altogether.

Details of the upfront payment must be included in the contract you created earlier. 

Discuss it with the client before the contract signing to establish transparency and ensure both parties are on board with the payment setup. 

Setting upfront payments creates a strong foundation for a healthy client relationship and protects your business from potential cash flow issues.

3. Create a Professional Invoice. 

Once the terms and conditions of the contract are clear to both parties, you can whip up a professional-looking invoice to send to your client. 

You can create your invoice from scratch or let one of those cloud-based invoicing software do the job for you. 

Whatever you choose, the invoice should contain these basic details:

• Business name and contact details
• Client contact details
• Company logo
• Payment terms and methods
• Invoice number and date
• Service details
• Total amount due (with taxes)

Doing this old-school invoicing may still work if you’re just a freelancer dealing with a few clients. 

However, agency owners or managers with a lot on their plates may find the manual invoicing process time-consuming. 

Not only is it tedious, but it also lacks the scalability agencies need to send and manage multiple client invoices at once. 

Fortunately, ManyRequests’ all-in-one client portal software includes integrated invoicing, which helps agencies generate client invoices quickly.

This means agencies won’t have to spend an arm and a leg on multiple apps, as everything they need to run their business smoothly is under one roof. 

The clients' experience is equally smoother, as they can easily make design requests, review the outputs, receive invoices, and complete payments from their self-service portal. 

Let’s learn more about ManyRequests’ invoicing in the following section. 

How ManyRequests Can Help You Automate Client Invoicing

Here’s how ManyRequests can help solve your invoicing troubles and keep your agency’s finances on track:

a. Professional Invoicing Template

ManyRequests offers built-in tools that allow you to create invoices in a few clicks. 

You can add all the necessary details—such as your business name, logo, contact information, client details, project name, and a breakdown of services—ensuring your invoices look professional and are easy to understand. 

You can download the generated invoice with one click and send it to your client manually. 

If you’re sending multiple client invoices, ManyRequests can simplify the entire process. You can create and send invoices directly through the platform or add them to the client portal, where clients can view and manage their payments. 

b. At-a-Glance Invoice Management

With ManyRequests, you can manage all your invoices in one centralized location. The platform provides a clear overview of your finances, including incoming payments and overdue invoices. 

You can even impersonate clients to see what the invoice looks like from their perspective, ensuring clarity and transparency in every transaction. This comprehensive view helps you stay on top of your financials and reduces the likelihood of missed payments or overlooked invoices.

c. Customizable Client Portals

One of ManyRequests's standout features is the ability to create customized client portals. These portals give your clients a dedicated space to log in, view invoices, manage payments, and communicate with your team. 

This feature reduces the need for back-and-forth emails, as everything related to billing and payments is accessible in one place. It’s a time-saver for you and your clients, ensuring smoother transactions and better communication.

d. Seamless Integration with Stripe

For agencies that need a reliable payment processing system, ManyRequests integrates seamlessly with Stripe.

This integration allows you to accept payments from major credit cards and manage all your subscriptions and invoices in one place. 

Whether it’s a one-time payment or a recurring subscription, Stripe handles the payment process automatically, marking invoices as paid once the transaction is complete. This automation ensures you don’t have to update payment records, reducing the risk of errors and missed payments.

e. Support for Manual Payments

While automation is key, there are times when clients may need to pay via alternative methods such as bank transfers, checks, or other manual processes. 

ManyRequests accommodates these situations by allowing you to manage manual payments within the platform. You can track these payments alongside your automated transactions, ensuring that all financial data is organized and easily accessible.

Automating your invoicing process with ManyRequests streamlines your workflow and significantly reduces the stress and time associated with managing payments. 

In addition to the features above, ManyRequests can also help you:

• Send payment reminders to your clients via the built-in chat messaging so your message won’t get lost in their emails. 
• Create recurring plans for your clients and charge them weekly, monthly, or quarterly to help you generate steady income.

4. Invoice Promptly and Accurately

A streamlined and efficient invoicing process minimizes delays and helps maintain a positive cash flow for your agency. 

Here’s how you can ensure your invoices are accurate and sent promptly:

a. Preemptive Communication

Sending a preemptive email to inform your client that an invoice will be sent soon can help prepare them for the payment and reduce the likelihood of delays. 

This pre-billing communication can prevent bill shock and ensure your client is ready to process the payment as soon as the invoice is received.

b. Issue Invoices Promptly

The faster you send out your invoices, the quicker you can expect payment. 

Make it a habit to issue invoices when a project milestone is reached, or work is completed. This will keep your cash flow steady and ensure the transaction remains fresh in your client’s mind, reducing the likelihood of delays.

c. Include All Required Information

Accuracy is crucial in invoicing. Ensure that every invoice includes all the necessary details to avoid disputes and payment delays:

• Name and Contact Information: Include your business name, address, and contact details so clients know who they’re paying.
• Customer Details: Clearly state the client's name, business address, and the correct department or contact person responsible for payments. Double-check this information to ensure its accuracy.
• Itemized Descriptions: Provide a detailed breakdown of the services or products provided. This helps clients understand what they’re paying for and reduces the chance of disputes.
• Accurate Costs: Ensure all prices, taxes, and applicable discounts are correctly calculated and displayed on the invoice.
• Payment Terms and Due Dates: Specify the payment terms and due dates to give your client a clear deadline for the payment.

d. Avoid and Resolve Disputes Quickly

Disputes over invoices can slow down the payment process significantly. To avoid disputes:

• Double-Check for Errors: Before sending an invoice, review it carefully to ensure there are no mistakes. This simple step can prevent many headaches later on.
• Resolve Disputes Promptly: If a dispute arises, address it immediately. Work with your client to reach a mutual agreement quickly so the payment process doesn’t stall.

5. Offer Incentives for Early Payment

Encouraging clients to pay their invoices on time can be challenging, but offering early payment incentives can be a powerful tool. Not only does it reward clients for settling their invoices quickly, but it also helps you recoup your money faster, improving your cash flow. 

Here’s how you can implement early payment incentives effectively:

a. Offer Discounts for Early Payment

One of the most straightforward ways to encourage early payment is to offer a discount to clients who pay within a specific time frame. 

For example, you could offer a 2% discount on invoices paid within seven days. This small percentage can encourage clients to prioritize your payment, especially if they’re managing multiple invoices from various service providers. 

b. Tiered Discount Levels

To further motivate early payments, consider implementing tiered discount levels based on how quickly the invoice is paid. For instance:

• 3% Discount: For payments made within three days.
• 2% Discount: For payments made within seven days.
• 1% Discount: For payments made within ten days.

This structure encourages prompt payment and gives clients flexibility, making it more likely they’ll take advantage of the discount.

c. Targeted Incentives for Specific Clients

You may also selectively offer early payment discounts, especially to clients with a good payment history. 

Segment your clients based on their payment data and offer discounts to those who consistently pay on time or benefit from a little extra motivation to pay promptly. 

This approach helps you build stronger relationships with reliable clients while encouraging better payment habits from others.

6. Consider Charging Late Payment Fees

You are not a bank, and your time is valuable. When clients delay payments, it’s only fair to impose penalties for the inconvenience caused. 

An automated billing system can be set up to add late fees to all overdue invoices. This eliminates the need for manual follow-ups and reinforces the importance of timely payments. 

By automating this process, you ensure consistency and fairness across all clients. Here's how you can put this into practice:

a. Communicate the Penalty Terms

To avoid surprises, ensure your clients are fully aware of your late fee policy before receiving their first invoice. 

Include a stipulation in your payment terms that clearly states the penalties for late payments. For example, specify that any invoice not paid within 30 days will incur a daily interest or a fixed late fee. 

It’s also important to know the maximum interest levels you can charge in your state to ensure compliance with local laws.

b. Offer a One-Time Grace Period

To maintain goodwill, consider offering a one-time grace period for first-time offenders. 

When a client misses a payment, you can politely remind them that your billing system will automatically add late fees to overdue invoices. 

However, as a gesture of goodwill, you can offer to bypass this fee if they settle the payment by a specific date. This approach encourages prompt payment and shows you can be flexible when necessary.

Here’s a template you can use:

Subject: Overdue Invoice Reminder and Late Fee Notice

Hi [Client’s Name],

I hope you’re doing well. I wanted to remind you that invoice [Invoice Number] is now overdue. Per our payment terms, a late fee will automatically be applied to unpaid invoices. However, as a one-time courtesy, I can waive this fee if payment is received by [Specific Date].

Please let me know if you have any questions or concerns. I appreciate your prompt attention to this matter.

Best regards,

[Your Name]
[Your Position]
[Your Company Name]

7. Follow Up Professionally

Even with the best invoicing practices, there are times when payments can be delayed. When this happens, following up professionally to maintain a positive relationship while ensuring you get paid is crucial. 

Here’s how you can approach this sensitive task:

a. Start with a Polite Reminder

If a payment is overdue, your first step should be to send a polite reminder. Depending on your client's preferred communication method, you can do this via email or instant messaging. 

If you manage your clients through ManyRequests, this is handled through a built-in messaging system where all project-related communications are stored in one place. This way, you won’t have to deal with a scramble of emails each time you check for invoice updates. 

The key is to remain professional and understanding—there could be various reasons for the delay, and showing empathy can go a long way in preserving the relationship. 

Here’s a template you can use:

Subject: Friendly Reminder: Invoice [Invoice Number] Due

Hi [Client’s Name],

I hope you’re doing well. I wanted to check in regarding the invoice [Invoice Number] that was due on [Due Date]. If everything is in order, please provide an update on the payment status. This will help us keep everything on track.

Please contact us with any concerns or if you need to discuss the payment. We’re happy to work out an arrangement that suits both parties.

Thank you for your attention to this.

Best regards,

[Your Name]
[Your Position]
[Your Company Name]

This approach is polite yet firm. It clearly states that you expect payment while also offering to address any client's concerns.

b. Establish a Follow-Up Schedule

Consistency is key when following up on unpaid invoices. Set a clear follow-up schedule that you can stick to. Here’s a suggested timeline:

• 7 Days Before Due Date: Send a reminder that the invoice is coming due.
• On the Due Date: Remind the client that payment is now due.
• 1 Week After Due Date: Send a polite follow-up email if the payment hasn’t been received.
• 2 Weeks After Due Date: Send a second reminder, setting a final deadline for payment.
• After 2 Weeks: Follow up with a phone call to discuss the late invoice and payment.

c. Maintain Professionalism and Empathy

Throughout your follow-up process, it’s essential to remain professional and empathetic. Understand that late payments can be sensitive, and aggressive or confrontational behavior can damage your client relationship. 

Maintain a positive attitude and emphasize that you’re open to finding a solution that works for both parties.

d. Know When to Walk Away

Sometimes, despite your best efforts, a client may consistently pay late or not respect your payment terms. 

In such cases, it’s important to recognize when it’s time to part ways. If a client is causing more stress than they’re worth, it may be best to discontinue the relationship. 

Your time and energy are valuable, and working with clients who respect your business practices will ultimately lead to a more successful agency.

Frequently Asked Questions. 

1. Can I invoice someone without a contract? 

Yes, you can invoice a client without a formal contract, but it's not the best practice. 

While you can still request payment for work done, having a written agreement makes the process smoother and legally clearer. A contract helps outline the project's terms, payment details, and what happens if there's a disagreement, making it easier to enforce payment if issues arise. 

2. When should you invoice your client? 

The best time to invoice your client is right after you’ve completed and delivered the work. 

Sending the invoice promptly keeps the payment fresh in your client's mind, making it more likely that you'll get paid quickly. 

Although it might feel pushy to invoice immediately, it’s a standard practice that clients expect. If your industry has different norms, like billing at the end of the month or after reaching certain milestones, discuss and agree on these terms with your client upfront.

3. How long after you invoice a client can you expect payment? 

Typically, payment is expected within 30 days of issuing the invoice, which is the standard in many industries. However, this can vary depending on what you and your client have agreed upon. 

Creative industries operate on shorter payment windows, like 14 days, while others allow more extended periods. It’s essential to set a precise due date on your invoice and to communicate any late fees if the payment isn’t received on time.

4. What should I do if the client is late paying invoices? 

If a client is late in paying an invoice, your first step should be to send a polite reminder. An email is usually sufficient to start, but if you don’t get a response, follow up with a phone call. 

It’s important to stay professional and not let the situation drag on—being prompt and transparent in your communication shows that you take your payment terms seriously. 

If late payments become recurring, consider discussing stricter terms or late fees with the client to avoid future problems.

5. How do you receive large payments from clients? 

For large payments, especially those that exceed the limits of services like Zelle, you’ll want to use more reliable methods like ACH transfers or paper checks. These methods are standard for significant sums and avoid the higher fees associated with credit card processors like Stripe. 

For convenience and scalability, many agencies set up payment processors like Stripe or Bankcard USA, allowing them to handle small and large payments efficiently. This also enables auto-billing, saving time and reducing the hassle of chasing down payments.

Wrapping Up. 

Running a successful agency can be financially rewarding. However, it can also cause you to lose much sleep, especially if you’re constantly chasing invoices. 

The article discussed above is packed with actionable tips on issuing invoices and ensuring they are converted to client payments.
