A Professional Dog Walker’s Guide to Tracking Bookings and Invoices for Free
A practical system that keeps your business organised without spending a penny
Running a dog walking business is wonderfully simple in one sense: dogs need walking, clients need help, and off you go with a pocket full of leads and a car that permanently smells faintly of wet Labrador.
However, behind the scenes there is a quieter job that determines whether your business runs smoothly or constantly feels chaotic.
That job is tracking bookings and managing invoices.
Many dog walkers believe they need expensive booking software to stay organised. In reality, plenty of very successful businesses run perfectly well using free tools and a clear system.
What matters is not fancy software. What matters is consistency, organisation and good habits.
This guide explains a simple professional system you can set up in under an hour.
The Three-Part Admin System
A reliable admin system for a dog walking business only needs three parts:
A booking tracker – to record every job
A calendar – to organise your daily schedule
An invoice system – to ensure you are paid
When these three pieces work together, you always know:
• who is booked in
• what services you are providing
• what clients owe
• what has already been paid
Without this structure, things slip through the cracks. And in a dog walking business, that usually means missed invoices and lost income.
Part 1: Creating a Master Booking Tracker
The booking tracker is the backbone of your business records.
It is simply a spreadsheet that contains every booking you take.
You can create this for free using:
• Google Sheets
• LibreOffice
Google Sheets tends to be the easiest option because it automatically saves your work and can be accessed from your phone.
What to Include in Your Booking Spreadsheet
Create columns for the following:
Client name
Dog name
Service type
Date of booking
Time of booking
Price
Invoice number
Payment status
Payment received date
Notes
Each row represents one booking.
Within seconds you can see:
• how busy you are
• what income is expected
• which invoices are still outstanding
Colour Coding Makes Life Easier
One very useful trick is colour coding payment status.
For example:
Green – Paid
Yellow – Invoice sent
Red – Payment overdue
When you open your spreadsheet you instantly see the financial health of your bookings without reading every row.
It is a simple visual system that saves time and prevents forgotten invoices.
With this sheet you can either add individual bookings, give them an invoice number and link them together or give a number of bookings on one line. You can easily see your monthly totals, whether you have sent invoices, when payments are overdue and when they have been paid.
Part 2: Using a Digital Calendar for Your Daily Schedule
Your spreadsheet tracks the business records. Your calendar manages the day-to-day work.
Trying to run a dog walking schedule purely from memory is a risky game. It only takes one missed booking for things to unravel quickly.
A free digital calendar keeps everything clear and organised.
Good options include:
• Google Calendar
• Apple Calendar
• Outlook Calendar
These calendars allow you to add each booking and set reminders.
How to Structure Your Calendar
Enter each walk or session as an event.
Example:
9:30 – Bella (Group Walk)
10:30 – Max (Solo Walk)
11:30 – Daisy (Puppy Visit)
This gives you a clear visual layout of your day.
Digital calendars are particularly useful because they:
• send reminders to your phone
• prevent double bookings
• allow you to check your schedule anywhere
If you employ staff or subcontractors, shared calendars can also help everyone stay coordinated.
This scheduler will automatically save to android but it is not currently compatible with apple. You can plan your day, adding start time, travel time and walk duration, it will then automatically work out for you the time you can start your second walk. You can add this to your google calendar or export the information. It is held in your local storage on your device.
Part 3: Creating a Simple Invoice System
Invoices are how your business gets paid. They must be clear, professional and easy to track.
Fortunately, creating invoices does not require special software.
You can build a simple invoice template using:
• Google Docs
• Microsoft Word Online
• Canva (free version)
Once you create the template, you simply duplicate it for each client.
What Every Invoice Should Include
A proper invoice should contain:
Business name
Your contact details
Client name
Invoice number
Date of issue
Description of services
Total amount due
Payment deadline
Payment method
Example:
TLC Dog Walking
Invoice #1045
Client: Sarah Jones
Services: 5 Group Walks
Total: £60
Payment due within 7 days.
This level of clarity prevents confusion and keeps things professional.
Why Invoice Numbers Matter
Every invoice must have a unique number.
This allows you to track payments accurately and keeps your records organised for accounting purposes.
A simple numbering system works perfectly.
Examples:
1001
1002
1003
Or:
2026-01
2026-02
2026-03
The key point is that each invoice number appears only once.
You should also record this number in your booking spreadsheet so you can match bookings to invoices.
Organising Your Files Properly
One of the biggest time-wasters in small businesses is poor file organisation.
The easiest solution is to keep everything in a cloud storage folder.
Good free options include:
• Google Drive
• Dropbox
• OneDrive
Create a main folder called:
Dog Walking Business
Inside it create subfolders such as:
Bookings
Invoices Sent
Paid Invoices
Client Forms
Contracts
Every invoice you send should be saved as a PDF inside the Invoices Sent folder.
When it is paid, move it into the Paid Invoices folder.
This keeps everything tidy and easy to find.
Building a Weekly Admin Routine
Admin becomes overwhelming when it is ignored.
The secret is a short weekly routine.
Set aside ten to fifteen minutes once a week to:
Check which invoices have been paid
Send any outstanding invoices
Update your spreadsheet
Record payments received
Think of it as a quick business check-up.
Regular small updates prevent the unpleasant moment when you realise several months of income has not been properly recorded.
Keeping Basic Records for Tax
In the UK, self-employed business owners must keep records of their income.
Your booking spreadsheet can easily double as a simple income tracker.
Add a column called:
Payment received date
When a client pays, record the date.
At the end of the month you can total the payments to see your income for that period.
This makes life much easier when completing a self-assessment tax return or working with an accountant.
Common Mistakes Dog Walkers Make
Many new dog walkers struggle with admin simply because they fall into a few common traps.
Relying on Memory
It might work when you have five clients.
Once you reach twenty or thirty, memory becomes unreliable.
Everything should be written down.
Not Sending Invoices Promptly
The longer you leave invoicing, the longer it takes to be paid.
Many professional dog walkers invoice:
• weekly
• fortnightly
• or monthly
Pick a system and stick to it.
Mixing Personal and Business Records
It is far easier to keep a separate folder and spreadsheet purely for business.
Even better, many dog walkers open a separate bank account for business income. This keeps finances much clearer.
When You Might Need Paid Software
Free systems work perfectly well for many dog walking businesses.
However, once you reach a larger scale with multiple staff members and hundreds of bookings, specialist software can become helpful.
Paid software often adds features such as:
automatic booking systems
online payments
client portals
automated reminders
But until your business reaches that level, a simple free system is often more than adequate.
Final Thoughts
A dog walking business may revolve around dogs, but its success depends on good organisation behind the scenes.
Tracking bookings and invoices does not require complicated tools or expensive subscriptions.
A clear spreadsheet, a reliable calendar and a simple invoice template are often all that is needed.
Once this system is in place, admin becomes quick and manageable. Instead of chasing paperwork or lost invoices, you can focus on the part of the job that actually matters.
Walking dogs, helping clients and building a business that works smoothly day after day.
A Note on The Dog House, Professionalism & Purpose
This space is written on one clear assumption:
you are a professional, not a casual pet lover with a lead and some spare time.
The Dog House exists because pet care, when done properly, is skilled work. It involves responsibility, judgement, boundaries, risk management, and decision-making — often under pressure and without applause.
Caring deeply does not mean operating loosely.
In fact, the more you care, the more structure you need.
You are allowed to:
• Treat your role as a profession, not a favour
• Expect clients to respect your time, policies, and expertise
• Put systems in place that protect your energy as well as your income
• Talk openly about boundaries, burnout, and business realities
• Acknowledge that loving animals does not mean tolerating poor behaviour from people
• Build a business that fits around your life, not one that consumes it
The Dog House is not about being harsh, cynical, or closed-off.
It is about being clear, grounded, and realistic.
Clarity reduces conflict.
Structure reduces stress.
Professionalism protects everyone — including the animals.
This space is here to support you in doing this work well, ethically, and sustainably, for the long term.
Because pet care businesses built on clarity and self-respect don’t just get by — they last.
