Here's a practical guide to doing it properly, without it eating your Sunday evening.

What needs to go on a dog walking invoice?​

As a sole trader in the UK, yours should include:

• Your name and address (or business name if you trade under one)
• Your client's name and address
• A unique invoice number
• The date the invoice was issued
• A description of the services provided
• The total amount due
• Your sort code, account number, or a payment link
• Payment terms (14 or 30 days is standard)

If your turnover is under the VAT registration threshold (currently £90,000), you don't need to charge VAT or include a VAT number.

Tracking the walks before you can invoice them​

The invoicing problem is really a record-keeping problem. If you've been tracking every walk in a notebook, a WhatsApp thread, or your memory, pulling that together at the end of the month takes time and leaves room for things to slip through.

The cleanest approach is to log each service as you go: date, dog, service type and price. By the time you're ready to invoice, the work is already done. You're just generating a summary of what you've already recorded.

What a good dog walking invoice looks like​

A well-structured invoice for a dog walking client shows each visit individually: the date, which dog, what service, and the price. The client can see exactly what they're being charged for, which means fewer questions, fewer disputes, and faster payment.

If you're looking after several pets for the same family, the invoice groups everything together clearly. Whether it's solo walks, group walks, home boarding or drop-in visits, each one shows up at the right price without you having to work it out manually each time.

By the end of the month, generating that invoice should take minutes.

Getting paid​

Bank transfer is the most common payment method for dog walkers in the UK. Include your sort code and account number clearly on every invoice, and add a payment reference you can recognise. Your invoice number works well for this.

Set clear payment terms upfront and include them on every invoice. Having a detailed, itemised invoice makes any late payment conversations easier. It's much harder to dispute a document that shows every walk.

What are your options?​

Once you've got a handle on the process, it's worth thinking about what tool you use to manage it. How you track and generate your invoices makes a big difference to how long it actually takes each month.

Your bank's built-in invoicing. Many business bank accounts now include a basic invoicing feature. It's free and good enough for very simple billing, but it won't handle individual walk tracking, multiple pets per client, or different service types at different rates. If your business is straightforward it might be all you need. If it's not, you'll hit its limits quickly.

Pet-specific business software. There are tools built specifically for pet sitting and dog walking businesses, and they're genuinely powerful. They include scheduling, staff management, GPS tracking, client portals, and much more. If you're running a team, they make a lot of sense. If you're a solo operator, you're paying upwards of £25–30 a month for features you'll never use, navigating a system designed for a business bigger than yours.

A spreadsheet. Most dog walkers start here. It works, but keeping it updated takes discipline and turning it into something you can send to a client takes effort every single month.

The part generic invoicing tools get wrong​

Most invoicing software works on the assumption that you're billing for a quantity of something. Five dog walks at £15 each. Simple enough on paper.

That's not how dog walking actually works. Your client doesn't just want to know they owe you £150. They want to see that Mondays and Wednesdays their dog went out, that you covered the bank holiday, and that the extra visit on the 14th is included. Line items by quantity don't tell that story.

If you're walking multiple dogs for the same client, or mixing walks with home visits or pet sitting stays, a basic invoice starts to look more like a puzzle than a professional document.

Built for solo dog walkers and pet sitters​

Simple Invoicing was built for exactly this: solo dog walkers and pet sitters who want professional invoicing without the complexity or cost of software designed for a team.

You log each walk or visit as you go. At the end of the month your invoice is ready: individual visits, correct dates, the right prices, ready to send. Client and pet details are stored so you're not re-entering them every time. At £9 a month it's less than the cost of a single walk.
