For advisory and law firms
Walk into the notary knowing which cheque each party brings.
Annexa runs the sale from start to finish and has the numbers ready: transfer tax or VAT and stamp duty, the 3% non-resident withholding, the bank’s provision and the seller’s mortgage. And in the Tax area, your client’s paperwork.
The hidden cost of every sale
Today, closing paperwork keeps one or more people busy. With Annexa, just one.
Every client’s sale is a steady drip of hours: settlement, withholdings, the bank’s provision, reports, NIE, tax representation and tax forms. Hours of qualified staff spent copying data and redoing sums.

How it is calculated and what it leaves out
On signing day the price minus what has already been paid changes hands. Out of it come the 3% if the seller is not resident (price × 3%), the cheque that cancels the seller’s mortgage and, whatever is left, the cheque to the seller. Costs are the regional transfer tax (standard rate) or, on new builds, VAT and stamp duty (AJD), plus an estimate for notary, land registry and agency; if the bank withholds them, they come out of the mortgage and the buyer puts in more at signing.
It is a guide: it leaves out municipal capital-gains tax, IBI, community fees, professional fees, other withholdings and reduced transfer-tax rates. Each sale in Annexa includes all of that.

Does Annexa replace my CRM?
No. Your CRM is for prospecting: listings, viewings and offers. Annexa starts when the buyer says yes and handles the reservation, the deposit contract, the signing and after-sales. They work together.
Is it only for international clients?
No. Annexa handles any property sale, with Spanish or international clients. For international ones it adds what usually complicates the closing: the 3% non-resident withholding, documents in English and the power of attorney to sign from abroad.
What if my buyer has no NIE yet?
Annexa shows that it is missing and tracks the process step by step: appointment, EX-15 form, 790-012 fee and collection. If the buyer lives abroad, they can get it online without travelling to Spain through the NIE service of Sarah’s firm: they sign a power of attorney before a notary online and a team of registered lawyers files it in Spain.

Can I try it before paying?
Yes. First we show it to you in a 30-minute demo with a sample sale. If you like what you see, we set it up with you on a video call. And from your first payment you have a 30-day guarantee: if it is not for you, we refund what you paid.
Does it work outside the Costa Blanca?
It was born in Alicante and Murcia. Transfer tax already adapts to each region; other regional particularities will come later.
Where is my data?
We explain it in detail in the demo: which providers we use (database, servers, email and artificial intelligence) and where each one operates. We would rather tell you properly than promise what we cannot.
