Key takeaways

• Establish a consistent billing schedule by setting aside dedicated time each week to create and send invoices, which prevents backlogs and maintains steady cash flow.
• Include all essential invoice elements such as your business details, customer information, unique invoice number, payment due date, itemised descriptions, and accepted payment methods to avoid delays and disputes.
• Bill more frequently by sending invoices weekly or immediately after job completion rather than monthly to improve cash flow and reduce administrative backlogs.
• Follow up on overdue invoices the day after the due date to train customers to pay on time and maintain healthy cash flow, as only 36% of invoices are paid on time without reminders.

What is an invoicing procedure?

An invoicing procedure is a repeatable system for creating, sending, and following up on invoices. It covers everything from tracking your work to collecting payment.

A clear procedure helps you:

• Bill consistently: send invoices on schedule instead of when you remember
• Reduce errors: include the right details every time
• Get paid faster: follow up promptly on overdue invoices
• Save time: spend less effort on admin and more on your business

Without a system, invoicing becomes reactive. You chase paperwork, miss details, and wait longer for payment. In fact, the average time to process an invoice manually is 14.6 days.

What to include on your invoices

Every invoice should contain the same essential details. Learn more about what an invoice is.

Missing information can delay payment or create disputes. Fixing each mistake can cost up to $53 when accounting for staff time and potential delays, according to research on invoice processing costs.

Include these elements on every invoice:

• Your business name and contact details: make it easy for customers to reach you with questions
• Customer's name and contact information: confirm you're billing the right person or company
• Unique invoice number: helps you and your customer track payments
• Invoice date: shows when the bill was issued
• Payment due date: sets a clear deadline for payment
• Itemised description of products or services: list what you provided with quantities, rates, and amounts
• Subtotal, taxes, and total amount due: break down the charges so customers see exactly what they owe
• Payment terms and accepted methods: specify how and when you expect to be paid

Using an invoice template or invoicing software helps you include these details automatically.

Connect quotes and invoices

Connect quotes to invoices by using the same descriptions and line items from your approved quote in your final invoice. This shows customers exactly what they agreed to pay for.

Get quotes signed off before starting work. Then mirror that language in your invoice to reduce disputes and speed up payment.

Track time and materials better

Track time and materials by recording the hours and expenses you spend on each job so you can invoice accurately. Without a system, you end up piecing together diaries, emails, and receipts when it's time to bill.

You need one source of truth for time and one for expenses. Apps can help:

• Time-keeping apps: clock in and out of jobs from your phone to capture billable hours automatically
• Expense apps: photograph receipts and attach them to specific jobs with Xero's expense apps so costs are ready when you invoice

Use invoice templates to their fullest potential

Invoice templates are pre-formatted documents that save time by storing your business details, common line items, and calculations. Many businesses start with spreadsheet templates before moving to dedicated software.

Get more from your templates by:

• Saving job-specific versions: pre-fill information for different types of work or repeat customers
• Building in formulas: automatically calculate totals, taxes, and discounts

As your invoice volume grows, consider upgrading to a dedicated invoice maker. Check out the Xero invoice template to get started.

Set a billing schedule

A billing schedule is a dedicated time you set aside each week to create and send invoices. Without one, invoicing gets pushed aside and cash flow suffers.

Pick a consistent day and time, then protect it like any other appointment. If you're stretched too thin, consider hiring a bookkeeper to help.

Invoice more often, get paid more often

Bill more frequently so money flows into your business more consistently. Many businesses invoice monthly, but that creates backlogs and delays payment.

Try these approaches instead:

• Bill weekly: prevents invoices from piling up and keeps cash flow steady
• Bill on completion: for one-off jobs, send the invoice as soon as the work is done to start the payment clock immediately

What could an invoice maker do for you?

Invoice maker software automates repetitive billing tasks to make your team more productive; for example, a full-time employee in an automated system can handle 23,333 invoices per year, compared to just 6,082 manually.

Here's how invoicing software speeds up your process:

• Stored pricing: saves your product and service rates so you don't re-enter them each time
• Automatic calculations: handles taxes and totals, and prepares paperwork for filing
• Payment tracking: reconciles with your bank daily to show which invoices are paid or outstanding
• Mobile access: lets you create and send invoices from your phone, anywhere

Should you accept online payments?

Online payments let customers pay directly from your invoice with a click. Businesses that offer convenient payment options get paid faster. For example, Stripe data shows customers pay 3x faster on average when using mobile wallets like Apple Pay or Google Pay.

Common options include:

• Debit and credit cards: widely accepted and familiar to customers
• Bank transfers: direct deposits with lower fees
• Payment services like PayPal: easy setup with built-in buyer protection

Most providers charge a small transaction fee, but setup is free. If your customers already pay on time, you may not need this. But if payments are slow, adding an easy option can speed things up.

Train your customers to pay on time

Train customers to pay on time by setting clear expectations from the first invoice. Early communication removes excuses and signals that you take payment seriously.

When you first bill a new customer, call to check the invoice has everything they need. If they miss the due date, follow up the very next day. You don't need to be aggressive. Just confirm nothing's wrong and show you're paying attention.

Keep this up over the first few invoices. Once customers know you follow through, on-time payment becomes the norm.

Chase invoices like you really want them

Follow up on invoices consistently. It's the most important part of getting paid. Even professional, accurate invoices often go unpaid without a reminder. Research on accounts payable indicates that only 36% of invoices in the U.S. are paid on time.

Send a reminder when the due date arrives. If payment still doesn't come through, pick up the phone. It takes persistence, but it's essential for healthy cash flow.

FAQs on invoicing procedures

Here are answers to common questions about setting up and managing your invoicing process.

How often should I send invoices to clients?

Bill weekly if you have regular work, or immediately after completing one-off jobs. More frequent invoicing means steadier cash flow and fewer backlogs.

What should I do if a client disputes an invoice?

Review the original quote or agreement, clarify any misunderstandings, and adjust the invoice if needed. Clear communication usually resolves disputes quickly.

Do I need invoicing software or are templates enough?

Templates work well when you're starting out or have low invoice volume. As you grow, software saves time with automatic calculations, payment tracking, and mobile access.

How long should I wait before following up on an unpaid invoice?

Follow up the day after the due date. A prompt reminder signals that you track payments closely and expect timely payment.

What's the difference between a quote and an invoice?

A quote is an estimate you provide before work begins. An invoice is a request for payment after you've delivered the product or service.
