An owner remembers a £60 grooming price, but checkout shows £72. Another sees a separate VAT line on their invoice and wonders whether they have been charged twice. Both questions can arise when the price entered, the price advertised and the invoice breakdown are not understood consistently.
For UK pet-care businesses, useful VAT settings need to reflect the business’s actual tax position and the intended customer price. This guide explains the difference between inclusive and exclusive amounts, shows a worked example and gives you a practical testing process for TailPro. Confirm your VAT treatment with your accountant before changing the setup.
Check these points before changing a VAT setting
- Registration: whether your business is VAT registered and the relevant effective date.
- Treatment: the correct VAT treatment for each service or item.
- Price basis: whether the amount you enter includes VAT or excludes it.
- Customer display: what owners see on your price list and during booking.
- Invoice: how the net amount, VAT and total appear where applicable.
- Existing commitments: what happens to earlier quotes, bookings and invoices.
- Verification: who checks the resulting figures before customers use them.
A setting labelled “VAT inclusive” is not a decision about your registration status. Nor does enabling VAT in software register your business with HMRC.
Establish whether VAT should be charged
HMRC’s charging guidance says a business must register for VAT before charging it. If you are not VAT registered, do not add a VAT charge simply because the software offers that option.
For a registered business, establish the treatment and rate that apply to what you sell. Do not assume every service, product or adjustment can share one treatment without checking.
Keep the distinction between tax decisions and software configuration clear. Your accountant can help determine the correct treatment; TailPro’s team can explain how the available settings implement it.
If registration is starting or changing, agree the effective date and handling of existing transactions before editing live prices. A general setting change may not resolve every booking or invoice affected by the transition.
Understand what the entered price means
VAT-exclusive means the amount before VAT. VAT-inclusive means the total already contains VAT. The final customer amount is often called the gross price; the amount before VAT is the net price.
For price lists aimed at the general public, GOV.UK explains that prices include VAT, where applicable. A system’s ability to store exclusive prices does not make an unexpected tax addition appropriate for a consumer-facing offer.
The invoice can show VAT separately while retaining the same final total. That breakdown explains the tax within the price; it does not necessarily represent an extra charge.
Example: the same £60 entry can produce different results
Illustrative business scenario — not a customer case study.
A VAT-registered grooming business is testing a service to which the 20% standard rate applies. These figures illustrate the calculation, not a recommended service price or a ruling on your particular supply.
| Meaning of the entered £60 | Net amount | VAT | Customer total |
|---|---|---|---|
| £60 already includes 20% VAT | £50 | £10 | £60 |
| £60 excludes 20% VAT | £60 | £12 | £72 |
For the inclusive price, £60 ÷ 1.20 = £50 net, leaving £10 VAT. For the exclusive price, £60 × 20% = £12 VAT, producing a £72 total. These calculations follow HMRC’s inclusive and exclusive pricing guidance.
Do not subtract 20% from a VAT-inclusive £60 to find its net value: that produces £48, which is the wrong calculation here.
Before saving the setting, decide whether the intended customer price is £60 or £72. The software should reflect that decision consistently.
Follow one booking from price list to invoice
Choose an ordinary service and write down the expected total. Then check each point where the owner encounters the price:
- Your website price list or written quotation.
- The selected service in the booking journey.
- Any selected extras or discounts.
- The final amount before payment.
- The booking confirmation and invoice.
Compare the same service, date and selections at every stage. A legitimate extra or discount can change the total, but the reason should be understandable.
If an invoice contains a VAT breakdown, check that the customer total still matches the agreed booking. For a partially paid booking, distinguish the total charge from the amount already paid and the balance outstanding.
Keep staff instructions consistent too. A telephone quotation should not use a different price basis from the online booking journey.
Test extras, discounts and changed bookings
A basic service may calculate correctly while a more complicated booking reveals a problem. Include a service with an add-on, an eligible discount and multiple quantities in your checks.
Confirm what each adjustment applies to and how tax and rounding are handled. Do not assume that copying a service also gives its extras the intended tax treatment.
For a moved, cancelled or partly refunded booking, check the appropriate accounting process rather than overwriting an issued invoice to make the numbers match. Ask your accountant how corrections should be documented and TailPro which controls support that process.
Our guide to pet-care pricing rules covers the separate question of how charges and discounts interact.
Check invoice information as well as arithmetic
A correct total is only part of a useful invoice. Review the business and customer details, invoice reference, service description, dates and amounts.
GOV.UK’s invoice guidance explains the general requirements and notes that VAT invoices require additional information. HMRC’s charging guidance also specifies the VAT number and separate VAT amount where applicable.
Have a sample invoice checked for the type of transaction your business makes. Do not assume that an attractive invoice or a VAT-labelled total automatically satisfies every requirement.
Keep your VAT registration details current, and check how invoice information is retained when settings change. Historical documents should not become confusing because today’s configuration differs from the one used when they were issued.
Where TailPro fits into the workflow
TailPro supports booking-related payments and invoicing. Its VAT article describes inclusive and exclusive presentation across checkout and invoices; confirm the exact controls and behaviour for your account before relying on them.
Ask the team to demonstrate your own example: the intended customer total, an extra, a discount and the resulting invoice. That is more useful than checking a setting in isolation.
Also confirm whether changing the setting converts stored prices or simply interprets the same entered amount differently. As the £60 example shows, the difference can materially change what customers pay.
Explore TailPro’s payment and pricing features and use a representative booking to assess the workflow.
Frequently asked questions
Should I enable VAT if my business is not registered?
Do not configure a VAT charge as though you were registered. Confirm the appropriate non-registered setup with TailPro and check your registration obligations separately with your accountant or HMRC.
Does a separate VAT line mean the customer pays more?
Not necessarily. A £60 VAT-inclusive total can be shown as £50 net plus £10 VAT. The payable total remains £60.
Will changing VAT settings update existing invoices correctly?
Do not assume so. Verify the treatment of existing bookings, issued invoices and corrections before making the change.
Does TailPro submit VAT returns to HMRC?
VAT presentation and invoicing do not establish VAT-return submission or Making Tax Digital functionality. Confirm any accounting or filing requirement separately; no such capability is claimed here.
Is there a free plan?
TailPro offers an ongoing Free plan without a monthly software subscription. Applicable transaction and off-app fees remain, and plan access varies. Check the current pricing and confirm the VAT controls you need.
Check one price all the way through
Choose a frequently booked service, establish its correct VAT treatment and intended customer total, then compare the booking and invoice. Use that example to test TailPro before changing your wider price list.
