Invoicing is often seen as just admin, but it can directly affect cash flow. Quick and easy invoicing helps you plan, invest, and grow.

Late payments remain a major issue for UK businesses, affecting over 1.5 million UK businesses and costing the UK economy around £11 billion each year. At the same time, 82% of SMEs report cash flow challenges. Businesses that grow consistently don’t just win work - they get paid quickly, with minimal friction between sending an invoice and receiving funds.

Here are 10 ways invoicing can support growth, and how you can use Zeller Invoices to make it easier to send invoices, track them and get paid.

1. Get paid faster by sending invoices instantly

Speed matters more than most businesses realise. It’s common to batch invoices at the end of the day or week, but even short delays between completing work and sending an invoice can push payments back further than expected. When that happens across multiple jobs, it creates a cash flow gap.

With Zeller Invoices, you can create and send invoices in as little as 30 seconds from the Zeller App or Zeller Dashboard, whether you’re off site or in the office. It’s the same as using an invoicing app, so customers can pay straight away while it’s fresh in their memory. And best of all: with no extra software costs. You can create and send invoices for free, from your Zeller Dashboard or from the Zeller App.

Create and send an invoice in under 30 seconds.

Over 75% of Zeller Invoices are paid in less than 24 hours.

2. Make it easier for customers to pay

Most late payments aren’t due to customers refusing to pay, they’re caused by delays. If paying requires logging into a bank account, entering details, or juggling different apps or platforms, it creates friction. The more friction, the more likely payment is delayed or forgotten.

Zeller Invoices lets customers pay in just a few taps using their card, removing extra steps and making it easier to pay straight away. You can send invoices by email or SMS, giving customers a quick, direct path to pay.

3. The best way to keep track of your invoices

As your business grows, manually tracking invoices naturally becomes more difficult. It’s easy to lose visibility over which invoices are still outstanding, especially when you’re managing multiple customers or projects.

It can be a lengthy task to keep track of your payments if you use a spreadsheet to keep track of your invoices, Zeller Dashboard gives you a live status view of invoice status, so you can see what’s paid, pending, or overdue in one place.

You can also use the Zeller Customer Directory to track invoices by customer, giving you a clear view of payment status across your client base. Assign contacts to invoices, personalise them for repeat customers, and manage payment terms on an individual basis as your business grows.

4. Strengthen cash flow with faster access to funds

Cash flow isn’t just about revenue, it’s about timing. You might have completed the work and received the invoice, but delays in accessing funds can still create pressure and limit your ability to plan ahead.

With payments settling into your Zeller Business Account overnight, you get a clearer view of your cash position. Faster access to funds helps you stay on top of payments, whether that’s suppliers or reinvesting in your business.

5. Reduce time spent on admin

Manual invoicing can be time consuming. Creating invoices, tracking payments, and following up all take time away from running your business.

Zeller Invoices brings everything into one place, helping reduce admin time and making it easier to manage invoices as your business grows. You can create and send an invoice for free in as little as 30 seconds, so invoicing doesn’t slow you down.

Just open a Zeller Business Account and start invoicing.

6. Get paid however your customers want to pay

Customers don’t all pay the same way. Some prefer to pay online immediately, while others may prefer to pay in person or by phone. Limiting payment options can create unnecessary delays.

With Zeller, you can offer multiple ways to pay, so customers can choose what suits them. You can:

Send invoices with built-in card payments.
Accept in-person payments with a Zeller card machine .
Process remote payments using MOTO .

Offering flexible ways to pay makes it easier for customers to complete payment, helping you get paid faster.

7. Use invoices to reinforce your brand

Invoices are often one of the final touch points a customer has with your business. While they’re primarily functional, they still shape how your business is perceived.

A well-presented invoice helps reinforce qyour brand at every touchpoint. With Zeller Invoices, you can customise invoices with your logo, brand colours, and a personalised message in just a few clicks.

8. Spend less time chasing payments

Chasing payments is one of the most frustrating and time-consuming parts of running a business. UK businesses spend an average of 86 hours a year chasing overdue invoices. It interrupts your day and takes your focus away from more valuable work.

With Zeller Invoices, you can schedule customisable automated SMS or Email reminders before, on, and after the due date. These reminders help encourage faster payment while removing the need for manual follow-ups, saving time across your day.

9. Connect incoming payments with your wider finances

As your business grows, it becomes more important to understand how money is moving in and out. When invoicing sits separately from your wider financial tools, it can be harder to get a clear picture.

With Zeller Business Account and Zeller Expense Cards, you can track payments and manage all your spending in one place, giving you a clear overview of your businesses finances. Zeller also integrates with accounting tools like Xero, helping keep your records up to date without extra manual work.

10. Grow your business without adding complexity

Growth often brings more customers, more invoices, and more to keep track of. Without the right payment system in place, it can become harder to stay on top of everything as your business grows.

Zeller Invoices is designed to scale with your business, helping you manage increasing volumes of invoices and payments without adding complexity or changing how you already work.
