Cairos for opticians and optometry

The invoicing software for opticians and optometry

Three VAT treatments live at the same counter: the sight test is exempt, prescription glasses go at 10% and sunglasses at 21%. And there is a detail almost nobody looks at: if you give the sight test away with the purchase, you never have an exempt transaction, and without one there is no prorrata to work out.

What changes

What is particular about invoicing in opticians and optometry

An optician's is half practice and half shop, and VAT treats it as two different businesses sharing the rent, the electricity and the staff.

The sight test is healthcare

Article 20.Uno.3º exempts care given to natural persons by healthcare professionals, and qualified optician-optometrists are among them. If you charge for the sight test or the eye examination as a separate service, that invoice goes without VAT.

Three rates on the same receipt

Prescription glasses, frames for prescription glasses and prescription contact lenses are on the list in the eighth annex to the Act, which article 91.Uno.1.6º.c puts at 10%. Non-prescription sunglasses and accessories go at 21%. It is a closed list: you check each line against it instead of assuming.

The prorrata depends on a commercial decision

If you charge for the sight test separately you have an exempt transaction, and with it a prorrata that stops you deducting in full the VAT on the rent and the electricity. If you include it in the price of the glasses, there is no separate consideration and there is no exempt transaction. Charging for it or giving it away is a commercial decision with tax consequences, and it is worth taking it knowing that.

Every order goes through the lab

Lenses are ordered cut to the customer's prescription and take days. In between there is a deposit, a frame set aside and a customer ringing to find out whether they have arrived. A pending order is not a sale: it is an obligation with a date on it.

Day to day

How it is done today, and how it looks with Cairos

In an optician's the margin is lost at the counter: in the wrong rate, in the forgotten order and in the stock of frames that has been hanging there for two seasons.

A real photo of the inside of a Spanish optician's: a frame display, the consulting room at the back with the phoropter and the counter with the till. Shop lighting, no recognisable faces.

Without Cairos

  • Everything is charged at 21%, including the prescription glasses that should have gone at 10%.
  • The sight test gets invoiced or not depending on who is in that afternoon.
  • Nobody has worked out the prorrata, and the VAT on expenses is deducted in full.
  • The order to the lab is written in a notebook and sometimes it gets lost.
  • Nobody knows which frames have not moved for months.

With Cairos

  • Every product carries its rate in the catalogue and the receipt comes out right on its own.
  • The sight test is a service with its own treatment, decided once.
  • If you charge for the sight test separately, the prorrata is worked out on its own and adjusted in December.
  • The order is recorded, with its deposit and its expected date.
  • The stock tells you what moves, what does not and how much margin each brand leaves.
Taxes

What VAT each thing carries in an optician's

The service and the product follow different routes, and the product also has two rates depending on what it is. Neither is inherited from the other.

ItemVATWhy
A sight test or eye examination by a qualified optician-optometrist, charged separatelyExemptHealthcare under art. 20.Uno.3º, which reaches qualified opticians.
Prescription glasses and frames for prescription glasses10 %They are on the list in the eighth annex, which art. 91.Uno.1.6º.c puts at the reduced rate.
Prescription contact lenses10 %Same annex, same closed list.
Non-prescription sunglasses21 %It is an accessory, not a medical product on that list.
Solutions, cases and accessoriesDepending on the productYou have to check each line in the eighth annex before assuming 21%.
Hearing aids and devices to make up for impairments10 %They come under the same annex, which is also a closed list: you look line by line.
Repairing or adjusting a frame21 %It is a service, and it is not healthcare.
Vision therapy with a therapeutic purposeExemptIt becomes healthcare again if it prevents, diagnoses or treats and a qualified professional provides it.

And a question worth settling with your accountancy firm rather than by habit: the recargo de equivalencia does not reach anyone who transforms the product before selling it, and fitting lenses cut to a customer's prescription into their frame looks a lot like transformation. Nor does it apply to commercial companies. It is not a decision to take by looking at what the optician's next door does.

Questions from opticians and optometry

At 10%. Prescription glasses, frames for prescription glasses and prescription contact lenses are on the list in the eighth annex to the VAT Act, which article 91.Uno.1.6º.c puts at the reduced rate. Non-prescription sunglasses are not on that list: they go at 21%.
It is your decision, but it has consequences. If you charge for it, it is an exempt service and with it you go into prorrata: you stop deducting in full the VAT on the rent, the electricity and the software. If you include it in the price of the glasses, there is no separate consideration for that service and no exempt transaction appears. It is worth deciding with the numbers in front of you.
Yes. The rate goes on the product's or the service's record, it is not chosen at the counter, so a receipt with an exempt examination, glasses at 10% and a solution at 21% comes out right without anybody having to remember. And the 303 comes out with each taxable base in its own box.
It is the question to settle with your accountancy firm before anything else. The surcharge does not apply to commercial companies or to anyone who transforms the product before selling it, and fitting lenses cut to measure into the customer's frame has a good deal of transformation about it. What you can do is not take it for granted: the regime and its exclusions are on the recargo de equivalencia page.
Yes. The order is recorded with its deposit, its supplier and its expected date, and it stays on the pending list until it is handed over. That is what stops a customer ringing to ask about lenses nobody ordered.
Yes, with stock by warehouse and transfers between them, so you know which shop each frame is in without picking up the phone. How many shops fit in each plan is on the pricing page.

Your optician's invoices differently. So does the program.
