Smarter invoicing software designed for any business. Online invoicing is an essential part of running any type of business, but it can sometimes be a source of stress and frustration. If it’s time to upgrade from sending invoices manually, or if your business is looking to streamline how you track and manage late invoice payments, you’re not alone. What if there was a free, simple-to-use online invoicing software that streamlines invoicing and helps you get paid faster? Introducing Zeller Invoices . With Zeller Invoices, you can create and send professional online invoices in seconds from anywhere. From there, it’s simple to track and manage every invoice from one convenient online dashboard. Whether you're a restaurant owner issuing an invoice for an event deposit; a tradesperson sending invoices to collect payment for work completed; a wholesaler supplying goods to a chain of retail businesses on a recurring basis; or a freelance designer sending invoices to multiple clients  — Zeller Invoices lets you take control of your invoicing from start to finish. Powerful invoicing features Read on to discover how Zeller Invoices works — and what features are under the hood to help save you time, and reduce late payments. Create an online invoice in seconds With Zeller’s online invoicing software, you can create and send as many online invoices as you like for free. You can start the invoice creation process in your Zeller Account in the “ Invoices” tab of the menu bar — you’ll be guided through a step-by-step creation of your first invoice, from attaching a contact (a customer, business or supplier) to your invoice from Zeller Contact Directory , through to adding items and the requisite price, adding a due date, and then hitting send. You can even choose to schedule a specific date in the future for your Zeller Invoices to be sent. If you need to make changes to an invoice, you can easily edit, duplicate or cancel the invoice if required. You can even check a PDF preview of your Zeller Invoices to see how they will look to the recipient before you send them. For detailed steps on creating and sending a Zeller Invoice, follow this guide in the Zeller Support Centre. Accept invoice payments online Every Zeller Invoice can be paid online via Zeller’s secure online payment gateway. Customers can select to pay the invoice online via Visa, Mastercard, American Express or JCB for one low, flat rate . There are no monthly subscription fees to use Zeller Invoices either — you’re only charged if a customer selects to pay their invoice online using Zeller’s online payment gateway. Invoices that are paid online will be settled to your linked Zeller Transaction Account nightly or the next business day to third-party bank accounts. For business owners who don’t have a physical location — such as a freelancer or mobile service provider —online payments are an easier way to ensure you’re getting paid faster, without having to meet in person or chase up cash payments or direct deposits. Streamline invoice creation with item management When creating an invoice with Zeller, you can choose to add one-off line items for goods or services sold. Alternatively, you can create a list of goods or services you sell frequently in your new item management service. Saved items can then be quickly added to future invoices sent. Within item management, you can choose to customise GST preferences or apply discounts for a percentage or dollar amount by item, that reflect your business’ pricing and individual scenarios with different customers. Item management is particularly handy for businesses that regularly sell the same products or services, such as an accountant offering a standard consultation fee, or a wholesaler with a standard purchase price on goods sold to retailers. By saving each item in your item management library, future invoice creation will be much faster. Automate reminders to prompt payment With data from Accenture and Xero estimating a $1.1 billion cost to Australian small businesses as a result of invoice payment delays, it’s essential that business owners are enlisting the right online invoicing software that reduces the impact of late payments on their business. Zeller Invoices enables you to schedule automated reminders to be sent to invoice recipients before, on, and after the invoice due date. A gentle reminder to your customer that payment is due will drive urgency towards payments, combined with the ability to automate reminders which also minimises impact on your busy schedule. You can also choose to send your own manual reminders, or edit reminders for a specific invoice or contact, in just a few clicks, too. Track payment status When you’re busy focusing on running and growing your business, it’s easy to forget the payment status of every invoice sent. Zeller Invoices makes tracking invoice status easier with a built-in activity timeline and next-action prompts. Your invoice activity timeline provides you with a chronological list of all the actions taken on an invoice, including creation, send and payment dates. At a glance, this log shows you detailed information about each action, such as the date and time, which employee performed the action and any added notes or comments — giving you complete visibility over the actions taken to get the invoice paid. With the next action prompts embedded within the activity timeline, you can quickly take action on an invoice; such as sending a reminder or marking it as paid in the event your client made payment outside of Zeller’s online payment gateway. Personalise your invoices Looking professional is paramount for any growing business — and that’s just as important when you’re invoicing, too. With Zeller Invoices, you can add your business logo to your PDF invoice, online payment page, and payment receipt. Adding your logo ensures that your business looks professional, and will make a strong and positive brand impression on your customers. With more invoice customisation coming soon to Zeller Invoices, you’ll always feel confident knowing your business is putting its best foot forward.

There’s a lot to think about when starting a business, and how to invoice your clients probably isn’t the most glamorous item on that list. But there’s nothing like getting paid for the first time – and to do that, you’ll need to create an invoice. If you haven’t done it before, making your first invoice can feel a bit daunting, but don’t worry, it’s easy once you know the basics.  In this ultimate beginner’s guide, we’ll explain what an invoice is and why they’re important, plus walk you step-by-step through how to create one from scratch. We’ll also discuss why good invoice design matters, and show how purpose-built invoicing software like Zeller Invoices can make the whole process much easier. By the end, you’ll be invoicing like a pro.  What is an invoice? Understanding the basics for your business. An invoice is a bill you send to a client for goods or services you’ve provided. It details what was provided, how much is owed, who needs to pay whom, and by when. Invoices create a formal record of a sale – they’re not just paperwork, but a critical part of managing your business’s finances. Why are invoices so important? For one, they help you get paid. A clear invoice tells your client exactly what to pay and by when, making it more likely you’ll receive payment on time. Proper invoicing also protects your cash flow, helps you maintain accurate records, and ensures you meet your tax obligations​. If you don’t get your invoicing right, it can result in delays that can seriously impact your business. Research has shown that late payments cost Australian small businesses around $1.1 billion in a year​. Finally, invoices are often required by law for taxes and accounting. They serve as evidence of income when you file your tax returns or Business Activity Statements. In short, a well-made invoice not only gets you paid faster, it helps keep your business organised and compliant. How to create an invoice from scratch. Ready to make your first invoice? Here’s a step-by-step breakdown of how to create an invoice from scratch. You can use a word processor (like Microsoft Word or Google Docs), a spreadsheet (like Microsoft Excel or Google Sheets), or an electronic invoicing solution like Zeller Invoices. The key is to include all the necessary details and present them clearly. 1. Start with your business details: At the top of the invoice, include your business name (or your own name if you’re a sole trader) and contact information. This typically means your address, phone number, and email. If you have a business logo, add it to give the invoice a professional touch. Crucially, add your Australian Business Number (ABN) on the invoice – we’ll explain why this is so important in the next section. 2. Add your client’s information: Next, list the recipient’s details. Include your client’s name (or business name) and their address. For businesses, it’s good practice to include their ABN as well, especially for larger invoices. Including the customer’s details personalises the invoice and ensures it’s clear who is being billed. It also helps you and the client to keep records. Note that if you’re invoicing another business and the total is over $1,000, Australian law actually requires you to include the buyer’s identity or ABN on the invoice​ – and there’s nothing wrong with including both. 3. Assign an invoice number and date: To help you track payments and refer to specific jobs, every invoice should have a unique invoice number, e.g. INV-01, INV-02, etc. Also include the date of issue (the date you’re sending the invoice). Invoice numbers and dates are crucial for record-keeping. They allow you to track your invoices chronologically and are helpful if you need to follow up on unpaid bills or sort out any confusion. 4. Describe the goods or services provided: Provide a clear, itemised list of what you’re billing for. In a simple table or list form, include each product or service, along with a short description, the quantity, and the price for each item or unit. Being specific here is important – it reminds the client exactly what they’re paying for, and prevents misunderstandings. 5. Calculate subtotals and include GST (if applicable): As you’ll see in the example above, you should show the subtotal (the sum of all item prices) and any GST, if applicable, on your invoice. GST is a 10% tax on most goods and services in Australia. You should indicate the amount of GST included in the price or add it on as a separate line. For a Tax Invoice (an invoice that includes GST), you can either list prices as GST-inclusive and note “Total price includes GST”, or show the GST amount for each item or for the subtotal separately​. If you’re not registered for GST, don’t add GST to your prices (it’s illegal), and don’t mark the invoice as a “Tax Invoice”. Instead, just call it an ‘Invoice’. Learn more about GST here. 6. Show the total amount due: This is the bottom-line figure you’re asking the client to pay. It’s usually in bold or otherwise highlighted for clarity. It’s a good idea to add a word like ‘due’ to subtly reinforce that action is required. 7. Specify payment terms and due date: This is a critical part of the invoice. Payment terms tell your client how and when to pay you. Common payment terms for small businesses might be “Payment due 14 days from invoice date” or “Net 30 days” (meaning the client has 30 days to pay). Choose a timeframe that suits your cash flow needs and industry norms – 7, 14, or 30 days are typical for many freelancers and small businesses. Also, do the maths and clearly state the due date by which you expect payment. Along with the due date, include your accepted payment methods. For example, you might write “Please make payment via bank transfer to the account below” and then provide your bank BSB and account number. If you accept other methods – such as credit or debit card or even cheque – list those options as well. Providing multiple payment options can make it easier for the client to pay promptly. 8. Add any additional notes: Many invoices include a short note or memo at the bottom. This could be a polite ‘thank you’ message, which adds a friendly touch. You might also include any other relevant details here, such as “Please include the invoice number as a reference when making payment”, which is helpful for matching payments to invoices. Once you’ve added all the above, give your invoice a final proofread. Make sure names are spelled correctly, amounts are right, and nothing is missing. If everything looks good, your invoice is ready to send! How to simplify your invoicing with Zeller Invoices.
