The CMA found pet owners overpaid £1 billion in five years. Itemised billing is how that stops.
The CMA's veterinary market investigation mandated three interrelated reforms: itemised billing (every invoice must separate individual charges), prescription fee caps (£21 for the first medicine, £12.50 for additional), and ownership disclosure on all client-facing documents. For independents, these are manageable individually but collectively they touch every invoice, every prescription, and every piece of client communication. Your agent validates every invoice against all three requirements: ensures itemisation is complete, caps prescription fees automatically, and includes ownership disclosure where required.
What Your Agent Actually Does
Your agent validates invoices against three CMA mandates simultaneously — itemised billing, prescription fee caps, and ownership disclosure — catching non-compliance before the invoice reaches the client.
Validates line-item separation on every invoice
Consultation, diagnostics, medications, consumables, hospitalisation — each must be a separate line item, not bundled into a single charge. Your agent checks every invoice for proper itemisation and flags any bundled charges that need breaking out.
Enforces prescription fee caps automatically
£21 for the first medicine, £12.50 for each additional — the CMA's prescription fee caps are specific and non-negotiable. Your agent checks every prescription charge against these caps and flags any that exceed them before the invoice is finalised.
Adds ownership disclosure to client-facing documents
The CMA requires practices to disclose their ownership structure on client-facing materials. Your agent ensures the required disclosure appears on invoices, estimates, and printed materials — particularly relevant for practices that have recently changed ownership or are part of a group.
Generates monthly compliance reports
How many invoices were fully compliant this month? Were any prescription fees above cap? Were any charges bundled rather than itemised? Your agent produces a monthly compliance summary that serves as evidence of systematic compliance — useful for CMA monitoring and practice governance.
Integrates with your PMS billing workflow
Your agent works with your existing invoicing process — reviewing invoices as they're created rather than requiring a separate compliance check step. Non-compliant invoices are flagged immediately, not discovered during an audit.
The real numbers.
| Practice manager time reviewing invoices for compliance | £2,000–£4,000/year |
| PMS reconfiguration for itemised billing | £1,000–£2,000 (one-off) |
| Prescription fee overcharge refunds and complaints | £500–£1,500/year |
| Realistic annual cost | £4,000–£8,000 |
| Agent build (one-off, configured to your PMS and billing structure) | £3,000–£5,000 |
| Monthly running costs (hosting + AI usage) | £120–£200/month |
| CMA regulatory updates | Included in first year |
| Realistic first-year total | £4,440–£7,400 |
Itemised billing sounds simple until you try to implement it across hundreds of invoices per month, each with different service combinations, medication charges, and consultation types. Add prescription fee caps and ownership disclosure requirements, and you have three compliance obligations touching every client transaction.
Your agent handles all three simultaneously, catching issues before they become complaints or compliance failures.
Good fit / not a fit.
This works brilliantly for:
- Practices processing 200+ invoices per month
- Practices that dispense medications regularly and need to track prescription fees
- Independent practices that need to demonstrate CMA compliance systematically
- Multi-vet practices where billing practices vary between clinicians
This probably isn't for you if:
- You already itemise every invoice and track prescription fees against CMA caps
- You have a dedicated billing administrator who manages invoice compliance full-time
- You rarely dispense medications (prescription fee caps are less relevant)
Let's talk.
We'll start with your PMS, your monthly invoice volume, and how you currently handle medication dispensing and prescription fees. Usually a 15-minute conversation.
