Introduction
When it comes to getting paid, clarity is key. Whether you're a freelancer, consultant, or small business owner, establishing clear payment terms ensures both you and your clients understand when payments are due, what’s expected, and what happens if deadlines aren’t met. Without clear terms, late payments and miscommunication can quickly derail your cash flow.
In this guide, we’ll cover the most common payment terms, how they work, and why they matter. We’ll also show how Otto AI makes it easy to implement these terms in your invoicing process, saving time and avoiding confusion.

What Are Payment Terms?
Payment terms are instructions included in invoices that outline how and when a client must make a payment. These terms define:
The payment due date
Early payment incentives
Late payment penalties
Accepted payment methods
By clearly defining expectations, payment terms help reduce late payments, minimize disputes, and improve your business’s financial health.
Why Are Payment Terms Important?
Having clearly defined payment terms serves several key purposes:
Improves cash flow: You know when to expect payments, making budgeting easier.
Encourages prompt payment: Clients are more likely to pay on time when terms are clear.
Protects your business: Legal clarity reduces the risk of payment disputes.
Builds professionalism: Clear terms signal to clients that you take your business seriously.
Platforms like Otto AI make it easy to set and manage these terms with automation that tracks due dates, sends reminders, and applies discounts or penalties as needed.
Common Payment Terms Explained
Here are the most frequently used payment terms and what they mean in practice:
1. Net 30
“Net 30” means the payment is due within 30 days of the invoice date. This is one of the most widely used terms across industries.
Best for: Ongoing client relationships or larger companies with longer processing times.
2. Net 15 / Net 60
These terms follow the same structure but with shorter (15 days) or longer (60 days) timeframes.
Net 15: Encourages faster payments.
Net 60: Often used for enterprise clients with complex billing systems.
3. Due Upon Receipt
Payment is expected immediately when the client receives the invoice.
Best for: One-off projects or new clients with no payment history.
4. 2/10 Net 30
The client gets a 2% discount if payment is made within 10 days. Otherwise, full payment is due in 30 days.
Best for: Encouraging early payments while still offering a 30-day window.
5. Cash in Advance (CIA)
The client must pay before any work begins.
Best for: High-risk clients or custom work requiring upfront investment.
6. Cash on Delivery (COD)
Payment is due at the time of delivery of goods or services.
Best for: Physical goods or services completed in person.
7. End of Month (EOM)
Payment is due at the end of the calendar month the invoice was issued.
Best for: Businesses that batch payments monthly.
8. Milestone Payments
Payments are made in parts as specific project milestones are completed.
Best for: Large or complex projects that span several weeks or months.
9. Installment Terms
The invoice is broken into equal, scheduled payments over a period of time.
Best for: Retainers, ongoing services, or budget-conscious clients.
With Otto AI, you can apply any of these terms to your invoices quickly and consistently using customizable templates.

Real-World Examples
A Freelancer’s Project
A freelance copywriter charges $2,000 for a website overhaul. They require:
50% upfront (Cash in Advance)
50% upon final delivery (Due Upon Receipt)
This ensures some income is secured before work begins, and the rest is collected promptly after completion.
A Marketing Agency Retainer
An agency offers social media management services for $1,500/month under Net 15 terms.
This gives the client two weeks to pay and provides a predictable monthly income stream for the agency.
A Web Development Firm
A $10,000 project is billed in three stages:
30% upfront
40% after milestone one
30% upon completion
Milestone payments protect both parties and reflect progress clearly.
How to Choose the Right Payment Terms
Selecting the right terms depends on factors like client reliability, project scope, and your cash flow needs.
Consider these questions:
Is the client new or established?
How large is the project?
Can you afford to wait for payment?
What are the standard terms in your industry?
You may want to use stricter terms (like Cash in Advance) for new clients and more flexible ones (like Net 30) for repeat clients with a solid payment history.
Otto AI allows you to assign different terms to each client, helping you stay in control while maintaining flexibility.
Invoicing Best Practices
To make your payment terms work effectively, follow these tips:
