Key takeaways

• Connect your quotes directly to your invoices by using the same descriptions, line items, and pricing to prevent disputes and speed up payment processing.
• Invoice more frequently rather than waiting for monthly cycles, as weekly billing or immediate invoicing after job completion creates steadier cash flow and gets customers paying sooner.
• Follow up on overdue payments the day after the due date with a friendly but professional call to signal you track payments closely and maintain consistent collection habits.
• Include complete invoice details such as business information, customer details, unique invoice numbers, due dates, itemised charges, and clear payment terms to ensure smooth processing and faster payment.

What is the invoicing process?

The invoicing process is the complete cycle of creating, sending, tracking, and collecting payment on invoices for your products or services. A well-organised process helps you get paid faster and keeps cash flowing into your business.

Here's how the cycle works:

• Create: Build an accurate invoice with all required details
• Send: Deliver the invoice to your customer promptly
• Track: Monitor which invoices are paid and which are outstanding
• Collect: Follow up on overdue payments and reconcile received funds

An organised process helps you avoid the delays and cash flow challenges that affect many businesses: research shows 49% of B2B invoices are overdue. The nine steps below show you how to build a system that works.

Start by linking your quotes to your invoices.

Connect quotes and invoices

Connecting quotes to invoices means using the same descriptions, line items, and pricing from your approved quote in your final invoice. This helps customers see they're getting exactly what they agreed to pay for.

Get quotes signed off before starting work. Then match your invoice to the quote to prevent disputes and speed up payment.

What to include in your invoices

A complete invoice includes all the information your customer needs to process and pay it. Complete details help ensure smooth processing and faster payment.

Include these essential elements:

• Your business details: name, address, contact information, and ABN or tax number
• Customer details: name, address, and any purchase order number they've provided
• Invoice number: a unique reference for tracking
• Invoice date: when you issued the invoice
• Due date: when payment is expected
• Itemised charges: clear descriptions of products or services with quantities and prices
• Total amount due: including any taxes or discounts
• Payment terms: accepted methods and any late payment fees (vendors commonly charge about 1.5% per month on overdue invoices, according to U.S. Small Business Administration guidance)

Optional but helpful:

• Payment instructions: bank details or online payment link
• Thank you message: a brief note to maintain goodwill

Check out the invoice template to get started.

Use invoice templates to their fullest potential

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

Get more from your templates by:

• Saving customer-specific versions: Pre-fill details for repeat clients and common job types
• Building in formulae: Automate totals and tax calculations to reduce errors

As your business grows, you may need a dedicated invoice maker with more features. Check out the invoice template.

How invoicing software speeds up your process

Invoicing software automates the repetitive parts of billing so you can send invoices faster and track payments in real time. According to research from Ardent Partners, teams using automation can process invoices in about three days, compared to 17 days for manual workflows.

Here's how it speeds up your process:

• Storing product pricing: Automatically pulls in your standard rates and service descriptions
• Calculating taxes: Handles tax calculations and prepares filing paperwork
• Reconciling payments: Shows which invoices are paid and which are outstanding through daily bank feeds
• Working on mobile: Lets you send invoices from anywhere using your phone

Track time and materials better

Tracking time and materials ensures you bill for everything you've done. A good system saves time and helps you capture every billable charge.

Use a single source of truth for time and another 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 so costs are ready when you invoice

Set a billing schedule

A billing schedule is a set day and time you dedicate to invoicing each week. A consistent schedule keeps invoicing on track and payments flowing.

Pick a consistent time slot and protect it. If you're too busy to manage invoicing yourself, hire a bookkeeper to help.

Invoice more often, get paid more often

Invoicing more frequently improves cash flow by getting customers on the payment clock sooner. Monthly invoicing creates delays on both ends: you're slow to send, and customers are slow to pay.

Consider these approaches:

• Bill weekly: Prevents backlogs and creates consistent cash flow
• Invoice immediately: Send invoices as soon as each job is done, especially for smaller or one-off work

The result is steadier income rather than unpredictable payments.

Should you accept online payments?

Online payments can get you paid sooner by removing friction from the payment process. For example, customers on average pay 3x faster when using digital wallets like Apple Pay or Google Pay. Other options include debit and credit cards, ACH services like PayPal, and direct bank transfers.

Most payment services are free to set up, though providers typically charge a transaction fee.

If customers already pay on time, your current process may be working well. But if payments are slow, adding a convenient option could speed them up. Find out how online payment services get you paid faster.

Train your customers to pay on time

Training customers to pay on time means setting clear expectations from the first invoice. It's about setting clear expectations and showing you take payment seriously.

When you first bill a new customer, call to check the invoice has everything they need. This courtesy also confirms they have everything needed to pay on time.

If they miss the due date, call the very next day. Keep the tone friendly and professional. Just check that nothing's wrong and signal that you track payments closely. Keep this up over the first few invoices to set expectations.

Chase invoices like you really want them

Following up on invoices is the most important part of getting paid. Even accurate, professional invoices often don't get paid on time without a reminder, but automated tools can make a significant difference, with some AI-powered systems recover 38% of failed payments on average.

Remind customers when the due date arrives. If they still don't pay, pick up the phone. It takes effort, but it's essential for your cash flow.

FAQs on invoicing process

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

How often should I send invoices?

Invoice as frequently as practical for your business. Weekly invoicing or invoicing immediately after each job improves cash flow by getting customers on the payment clock sooner.

What information must be included on an invoice?

Every invoice needs your business details, customer details, a unique invoice number, date, due date, itemised charges, total amount, and payment terms. Complete information helps ensure timely payment.

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

Follow up the day after the due date. A prompt reminder signals you track payments closely and confirms they have everything needed to pay.

Do I need invoicing software or can I use spreadsheet templates?

Spreadsheet templates work for simple needs, but invoicing software saves time as you grow by automating calculations, tracking payments, and sending reminders.

What's the difference between invoicing and billing?

Invoicing is creating and sending a request for payment. Billing is tracking what customers owe, sending invoices, and managing payments received.
