Software for property developers: sell your new build unit by unit.

Developments with their unit types and units, live availability, a mortgage and costs calculator for buyers, and reservations and deposits with e-signature. For developers who sell direct and for agencies marketing third-party developments.

  • Unit types and units
  • Signed reservations and deposits
  • 14-day trial
The problem

Selling a development with spreadsheets is selling blind.

A development has dozens of units, several sales agents and buyers at different stages. The availability list usually lags behind reality.

Out-of-date availability

Two agents offer the same home because the sales office spreadsheet was not updated.

Numbers worked out by hand

Every buyer asks what they will pay a month and how much they need saved, and each agent works it out differently.

Paper reservations

Reservation and deposit documents filled in by hand, with the risk of errors in the unit, price or amounts paid.

Prospects who go cold

Whoever asked about a type B months ago never hears that one has become available.

How FixrOS does it

New-build sales software, inside the Brokerage module.

Developments

The development, its unit types and every unit, in one place.

You set up the development with its developer, define the unit types (for example two and three bedrooms, penthouses, ground floors with garden) and load the units with their floor, area and price. Each unit has its status, so the whole team sees what is free, what is reserved and what has a signed deposit.

  • Developments and developers
  • Unit types and units
  • Status of every unit
  • Alongside the rest of your portfolio
Calculator

Mortgage and costs, worked out in front of the buyer.

The FixrOS mortgage and costs calculator helps you answer the two questions every buyer asks: how much will I pay a month, and how much do I need saved? Enter the unit price, deposit, term and interest rate, and you see an estimate of the monthly payment and purchase costs. It is a sales guide; the binding offer always comes from the bank.

  • Estimated monthly payment
  • Purchase costs
  • Savings needed
Reservations and deposits

Reservation and deposit for each unit, with e-signature.

When a buyer picks their home, you generate the reservation document from the unit and then the deposit contract, with the development, unit and buyer details already filled in. They are signed electronically and the unit's status changes for the whole team. Documents are available in Spanish, Catalan, English and Galician, handy when the buyer is from abroad.

  • Reservation and deposit from the unit
  • E-signature
  • Spanish, Catalan, English and Galician
  • Unit status up to date for everyone

Practical guide

What to know when selling new builds in Spain

Payments on account must be guaranteed

In new builds the buyer usually pays part of the price before receiving the home: reservation, deposit and stage payments during construction. The first additional provision of Law 38/1999 on Building Regulation requires anyone developing homes who wants to collect payments on account during construction to guarantee their refund, plus statutory interest, through a surety insurance policy or a joint bank guarantee, in case the works do not start or are not completed within the agreed period. Those payments must also be received through a credit institution, into a special account kept separate from the developer's other funds.

For the agency marketing the development, this boils down to a question to ask before signing the first reservation: is the guarantee in place, and which is the special account? Putting it in the document reassures the buyer and prevents problems later.

What taxes a new-build buyer pays

The first delivery of a new home by the developer is subject to VAT. Article 91.Uno.1.7.º of Spanish VAT Law 37/1992 applies the reduced 10% rate to buildings or parts of buildings suitable for use as homes, including up to two parking spaces and annexes transferred with them. Second and subsequent deliveries are VAT-exempt (article 20.Uno.22.º) and, as a rule, fall under Transfer Tax (ITP).

In addition, the first copy of the public deed of sale is subject to Stamp Duty (AJD) at the rate approved by each autonomous community, under article 31.2 of the consolidated ITP and AJD Law; if the community has not approved one, 0.50% applies. That is why the costs calculator gives an estimate: the exact rate depends on the region and sometimes on the buyer's circumstances.

The information the buyer is entitled to see

Royal Decree 515/1989 requires anyone selling homes to consumers to make available, among other things, the site and home plans, a description with usable floor area and the materials used (article 4), and an explanatory price note including the total price, with the agent's fees and VAT where the sale is subject to it, and the payment terms (article 6). And Royal Decree 390/2021 requires the energy label in advertising, stating whether it refers to the project certificate, the completed building or an existing building (article 15.2).

Having every unit properly described in FixrOS, with its floor area, type and price, makes it easier to prepare that documentation and ensures every agent gives the same information. If the development is also shown on the office's digital window, the details come from the same record.

When the development is finished, management begins

A delivered development becomes a new owners' association, and often flats that investor buyers want to let. In FixrOS those steps live in the same system: property management for the new community in the Communities module and rental management in the Portfolio module, on the same properties and the same people.

FAQ

Questions about new-build software

Is it for developers or only for agencies?

For both. A developer selling its homes direct uses developments, units and reservations; an agency marketing third-party developments keeps them alongside the rest of its portfolio.

How is a development organised in FixrOS?

With the development and its developer, its unit types and its units. Each unit has its floor, area, price and status (free, reserved, under deposit), visible to the whole team.

What does the mortgage and costs calculator work out?

An estimate of the monthly payment based on price, deposit, term and interest rate, and of the purchase costs. It is indicative: taxes depend on the autonomous community and the binding offer comes from the bank.

What VAT applies to a new-build home?

As a rule, 10% on the first delivery of buildings or parts suitable for use as homes, including up to two parking spaces and annexes transferred with it (article 91.Uno.1.7.º of Law 37/1992). The deed also pays AJD at each autonomous community's rate.

Can the reservation and deposit be signed remotely?

Yes. FixrOS generates the documents with the unit and buyer details, in Spanish, Catalan, English or Galician, and they are signed electronically.
