Invoice Management Tips for Small Businesses

Dealing with invoices might be among your least favourite tasks, but when you’re a small business owner, it’s one of the most important. Good invoice management encourages regular cash flow, eases accounting woes and saves you time. So you’ll want to make sure you have a simple strategy for generating, sending and keeping track of them.

Find out how to get a handle on invoices so that you can get back to work.

What is invoice management? 

Invoice management refers to all the systems and processes involved in sending and receiving invoices. As a vendor, it includes the way you create, send and track customer invoices. When you’re the one making a purchase from a supplier, invoice management entails receiving and reviewing invoices, as well as approving and paying them. 

Why is invoice management important for small businesses?

Picture this: It’s tax season and your accountant asks you for all invoices sent to a specific customer. You thought you had them saved on your computer, but made a typo in one of the name files. You spend an hour locating the missing invoice. 

Here’s another scenario: You forget to pay a supplier because you’ve been extra busy opening a second location for your business. Now there are late fees, and you feel awkward about the situation. 

Or maybe you realize months after delivering a service and invoicing a customer that you haven’t been paid for it — and your cash flow is currently negative. 

These are the types of challenges proper invoice management helps you mitigate. It reduces the risk of errors, protects your cash flow, helps you maintain positive relationships with suppliers and keeps records organized for tax purposes, such as collecting and remitting the GST/HST, filing yearly income tax reports and being prepared if you ever get audited by the Canada Revenue Agency (CRA). 

Invoice management tips 

Since invoice management includes several different tasks, it’s important to choose the right processes and tools for your unique business needs. Here are invoice management tips to help you save time and streamline operations.

Choose the right type of invoice for the job

There’s no one-size-fits-all invoice template — different payment plans work for different projects. So before you begin the work, talk to your client or customer about a payment schedule that works best for both of you and make sure you agree upon one plan. Here are some options to consider:

Use automated invoice management 

Whether you need to send recurring invoices on a monthly basis or just want to create one-off invoices, there’s no need to spend hours on manual work. Automated invoice management can help you run the following tasks on autopilot: 

Manage invoices online

A quick way to reduce headaches and streamline your invoicing process is to eliminate paper from the equation. Paper invoices have a way of piling up (for both you and your clients) — they’re a headache to manage, and it’s easy to lose track of their status.

Enter modern invoicing software, which eliminates the need for paper and supports various aspects of invoice management, from invoice creation to record-keeping and analytics. You can send invoices online, add convenient online payment links to your invoices and automate several tasks and processes. 

If you’re wondering how to choose the right invoice management solution, there are a few factors to consider. 

 

Square Invoices checks all those boxes. You can send customized, professional invoices and check the status of every client from your computer or mobile device. You can also send invoices from your device using our invoice app and your customer won’t be charged a fee to pay.

Square Invoice software allows customers multiple, secure ways to pay, whether it’s by credit card, Apple Pay, Google Pay or Afterpay online. You can apply discounts and GST/HST with a few clicks. And you get access to your funds as soon as the next day. 

“Setting up invoices is really easy when I do private parties and weddings; it cuts out extra paperwork that needs to be done. They are just so easy to customize at the drop of a hat. You can change menu items, change the price, add HST, add discounts—all that kind of stuff,” said Sylvia Zietek, owner of Pierogi Queen in London, Ontario. 

Square makes it easy to automate invoicing tasks like sending payment reminders or scheduling recurring invoices. Plus, Square Invoices seamlessly syncs with accounting tools to help you stay organized. “Having my sales, invoices and expenses integrated and automated takes some of the pressure off me by reducing the amount of paperwork and organizing I have to do,” said Diona Joyce, owner of Tita Flips in Toronto, Ontario.

Common invoicing mistakes
