What is the invoicing process?

The invoicing process is the complete workflow of creating, sending, and collecting payment for bills you issue to customers. It covers everything from finishing a job to the moment money lands in your account.

A solid invoicing process helps you get paid faster and keeps your business running smoothly, protecting you from the late payments estimated to cause 50,000 business closures annually. For small businesses, the benefits include:

• Faster payments: Clear, timely invoices get paid sooner
• Better cash flow: Consistent billing keeps money moving into your business
• Fewer disputes: Accurate invoices reduce back-and-forth with customers
• Less admin time: A repeatable system cuts down on manual work

The nine steps below will help you build an invoicing process that works, so you can spend less time chasing payments and more time running your business.

How the invoicing process works

Before diving into specific tactics, it helps to see how all the pieces fit together. Here's the journey your invoices take from start to finish.

The invoicing workflow follows a predictable path: you complete the work, create an invoice, send it to your customer, track payment, and reconcile the transaction in your accounts. If payment doesn't arrive on time, you follow up.

The nine steps in this guide help you optimise each stage of this workflow. They cover everything from setting up a billing schedule to chasing overdue payments, so you can build a system that keeps cash flowing into your business.

1. Set a billing schedule

A billing schedule is a fixed time you set aside each week to create and send invoices. It turns invoicing from an afterthought into a priority.

Prioritising invoicing alongside paid work keeps your cash flow healthy. Pick a day and time each week to get it done, then lock it into your calendar. If you're too busy, hire a bookkeeper to help.

2. Invoice more often, get paid more often

Frequent invoicing gets money into your account faster. The longer you wait to send a bill, the longer you wait to get paid.

Many businesses invoice once a month, but more frequent billing offers advantages:

• Faster payments: Prompt invoices lead to prompt payments
• Lighter admin load: Work stays manageable throughout the month
• Consistent income: Money flows steadily into your account

The Federation of Small Businesses reports that more than half of small businesses experience late payments that affect their cash flow.

Consider billing weekly instead. Or, if you do lots of odd jobs, send invoices as soon as the work is done. It gets your customers on the clock sooner and keeps money flowing more consistently.

3. Connect quotes and invoices

Linking quotes to invoices reduces disputes and speeds up payment. When customers see familiar descriptions from the original agreement, they're more confident paying promptly.

Have customers sign off on quotes before starting work. Then use those same descriptions in your invoice so they can see they're getting what they paid for. This encourages prompt payment.

4. Track time and materials better

Accurate time and expense tracking makes invoicing faster and improves accuracy. With good tracking, you can send bills quickly instead of piecing together diaries, emails, and receipts.

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. Learn about online timesheets
• Expense apps: Photograph receipts and attach them to specific jobs. Explore expense apps

When you capture everything as you go, invoicing takes minutes instead of hours.

5. Use invoice templates to save time

Invoice templates are pre-formatted documents that speed up billing by eliminating repetitive data entry. Many businesses use spreadsheet templates, but they work best when you set them up properly.

Get more out of your templates by:

• saving versions with pre-filled information for specific job types and customers
• building in formulae that total charges and calculate taxes automatically

Make sure your templates include all required information: your business name and address, customer details, unique invoice number, dates, descriptions, amounts, value added tax (VAT) if registered, and payment terms.

As you grow, you may move onto dedicated invoicing software. Check out this invoice template to get started.

6. Automate your invoicing process

Invoice automation uses software to handle repetitive billing tasks, so you spend less time on admin. It's one of the fastest ways to improve your invoicing process.

A Gartner survey shows the percentage of finance functions adopting artificial intelligence (AI) tools more than doubled from 21% in 2023 to 58% in 2024.

Invoicing software can automate tasks like:

• Calculating prices and taxes: Store your rates and apply them automatically
• Reconciling bank transactions: See which invoices are paid and which are overdue
• Sending payment reminders: Follow up with customers without lifting a finger
• Creating recurring invoices: Bill regular customers on a set schedule
• Invoicing on the go: Send invoices from your phone, anywhere

The right invoicing software connects to your accounting system, so data flows through without manual entry. That means greater accuracy and faster payments.

7. Accept online payments

Online payment options get you paid faster by removing friction for your customers. Some invoice financing services make cash available within 24 hours of uploading a bill. The easier you make it to pay, the sooner your customers will do it.

Popular options include:

• Debit and credit cards: Offer familiar, convenient payment for most customers
• Digital wallets: Accept Apple Pay, Google Pay, and similar services
• Bank transfers: Receive direct payments with no card fees
• Payment services: Use PayPal and other automated clearing houses

Most providers charge a small transaction fee, but setup is free. If your customers already pay on time, your current setup works well. For customers who need extra encouragement, an easy payment option can help.

With Xero's Tap to Pay feature, you can accept contactless payments directly from your phone, making it simple for customers to pay invoices on the spot.

8. Train your customers to pay on time

Payment training means setting clear expectations with new customers from the start. It's about establishing habits that lead to on-time payments.

When you first bill a new customer, call them to check the invoice has everything they need. It's a nice courtesy that also sets clear expectations for timely payment. If payment hasn't arrived by the due date, call the very next day. Keep the tone friendly and professional. You're just making sure nothing's wrong and signalling that you watch this closely.

Keep this up over the first few invoices. Once customers know you follow up promptly, they're more likely to prioritise your bills.

9. Chase invoices like you really want them

Following up on invoices is essential to the invoicing process. Even with accurate, professional invoices, reminders help customers pay on time.

UK law states that if you and the customer don't agree on a payment date, a payment is late 30 days after the customer receives the invoice or you deliver the service. Remind your customer when the due date arrives, keeping in mind that agreed payment dates must usually be within 60 days for business transactions. If payment is still outstanding, get on the phone. This effort is hugely important for your cash flow.
