BILLING AND TAXATION POLICY — VERSION 0.1 (DETAILED DEVELOPMENT)
This Policy details the issuance, management and retention of financial documents under the current version 0.1: Wisdom issues documents for its own transactions and allows documents issued by the Service Provider to be uploaded. It does not offer to issue documents for or on behalf of Service Providers.
Wisdom is a brokerage platform. Therefore, the same reservation may comprise two legally differentiated operations: the service provided by the professional to the client and the platform services provided by Wisdom.
This separation determines who must issue each invoice and who assumes the corresponding tax obligations.
1. Two different economic concepts
The price of a reservation can be made up of:
Settlement of the professional: amount corresponding to the service performed by the professional.
Wisdom service fee: amount corresponding to the intermediation services, infrastructure, payments, support and other functionalities provided by Wisdom.
Unless there is an applicable Premium benefit, the ordinary Service Fee is 10% of the professional's settlement + €0.50, with a minimum of €1.
Both concepts can be part of the same payment to facilitate the customer experience, but they correspond to different operations and may require separate tax documentation.
2. Service Fee Invoice
Where legally applicable, Wisdom will issue the invoice for its own Service Fee.
This invoice will document exclusively the services provided by Wisdom and not the professional activity carried out by the provider.
The invoice will identify Oier Hernanz Arroyo as the issuer, under the trade name Wisdom, with his current tax details; the recipient where applicable; the transaction, the amount and the applicable taxes. “Wisdom, S.L.” will not be used as though it were the issuing entity.
The professional is not the issuer of this invoice nor is it liable for Wisdom's own income.
3. Professional service invoice
The material provision of the service is carried out between the professional and the client.
The invoice for the work, when there is a legal obligation to issue it, will be issued by the Provider to the Client through its own means and may be attached to the reservation.
The professional continues to be the taxpayer with respect to said operation even if the payment has been processed through Wisdom.
The use of the platform does not convert Wisdom into the service provider nor does it transfer to Wisdom the tax obligations of the professional.
4. Documents provided by the Lender
The Provider generates and issues its invoice outside the Wisdom issuing system, with its identity, numbering, content and taxes.
The Service Provider may upload the file to the booking so that the Client can view or download it. This action authorizes the necessary storage and availability, not the issuance of documents by Wisdom on the Service Provider’s behalf.
The Lender remains the issuer and responsible for the authenticity, accuracy and tax compliance of the document. Wisdom does not sign or issue the invoice for the Service.
Format, technical integrity or file security controls are not equivalent to an audit of the invoice or a validation of its tax treatment.
Wisdom may record who provides the document, the reservation, the time of upload and its history, with the guarantees and conservation limits of the Privacy Policy.
5. Responsibility for data and document
Attaching an invoice to Wisdom does not modify the Lender's tax responsibility.
The professional must keep the data necessary to issue their documents correctly updated and will be responsible, among other aspects, for:
Your identity and NIF or tax identifier.
Your tax address.
Your tax situation.
The tax treatment of your activity.
The type of VAT or other applicable tax.
Possible exemptions.
The assumptions of reversal of the taxable person when applicable.
Any other necessary tax information.
Wisdom does not audit registrations or the declared tax situation and does not provide personalized tax advice. Identity checks, payments, diligence and legally required communications are maintained, and the possibility of acting in the event of signs of irregularity.
6. Individual and Self-Employed / Company
Individual is the natural person who selects and confirms that condition without Wisdom having audited their tax situation. Self-employed / Company is someone who declares to be registered and act as a businessman or professional. Both categories describe stated information and not accreditation from Wisdom.
The actual legal status depends on the activity. A label does not exempt from taxes, registrations, invoices or licenses. Whoever is obliged must issue their document, correct its classification if it is incorrect and deliver it by an appropriate means even if a function of the app is not available.
The declaration is made when setting up the payout method and must be kept up to date. Self-Employed / Company requires express acceptance of its accuracy and responsibility, with the scope established in the Terms. Not having a payout method or not having answered does not constitute a declaration of acting as a private individual.
7. Issuance and content of invoices
The invoices issued by Wisdom will incorporate the information required by the applicable regulations. The Provider must guarantee by its own means that its invoice meets the corresponding requirements.
Where applicable, they may include:
Number and series.
Issue date.
Date of the operation when different.
Identification of the issuer.
Identification of the recipient when necessary.
Service description.
Tax base.
Tax rate.
Tax fee.
Total amount.
Special tax mentions when applicable.
Reservation reference.
The invoice file supplied by the Service Provider will retain its original issuer and content. Wisdom will not replace the Service Provider’s identity with the platform’s brand or generate a consolidated invoice for the work in Wisdom’s name.
8. Numbering and series
Invoices must maintain an orderly and correlative numbering within the corresponding series.
Wisdom will use its own series for its invoices and corrective invoices. It will not assign or use up Service Providers’ tax invoice numbers; each Service Provider will manage their series outside Wisdom’s invoice issuance system.
The corrective invoices will use the specific series that correspond in accordance with the applicable regulations.
The number of an invoice already issued cannot be reused for a different operation.
9. Invoices already issued
An issued invoice is not silently modified or replaced when the circumstances of a transaction subsequently change.
When an invoice must be corrected in accordance with applicable regulations, the corresponding corrective document will be issued.
This preserves traceability between the original document and any subsequent corrections.
10. Corrective invoices and refunds
A cancellation, refund or adjustment of the amount may require a rectification of a previously issued invoice.
Where applicable, Wisdom will generate a corrective invoice for its own amounts.
For example, if a previously invoiced Service Fee is returned in whole or in part, the system may generate the necessary tax document to reflect such modification.
If the invoice concerns the work, the Service Provider must issue and supply the corrective invoice. Wisdom may record the refund and host the document, but does not generate or correct it on the Service Provider’s behalf.
In the interface, Wisdom may use more understandable names such as “Refund”, as long as the tax document retains the corresponding legal nature internally and in its content.
11. Final price adjustments
In certain services, especially those charged by the hour or under a budget, the final amount may not coincide with the initial estimate.
If the professional settlement increases, the Service Fee may also increase and documentation corresponding to the additional amounts may be generated.
If the final amount decreases and there is a return of previously invoiced amounts, the legally corresponding rectifications will be made.
The documents issued will always reflect the amounts actually applicable to the final operation.
12. Deposits
The deposit is part of the economic system of the reservation and does not necessarily constitute an independent concept of the final price.
Its documentary treatment will depend on the nature of the amount being charged and the applicable regulations.
When an advance payment corresponding to a Wisdom operation must be documented by invoice, Wisdom will issue the corresponding document.
If said amount is subsequently returned or adjusted, the appropriate tax regularization will be carried out.
13. Wisdom Premium
When Premium eliminates the ordinary Service Fee, only the amounts that actually correspond to Wisdom will be documented.
The Premium application does not modify the professional's responsibility for the billing of their own service.
In recurring reservations, each session will maintain the economic and fiscal conditions that correspond to it based on the rules applicable at the time it is established or the corresponding payment occurs.
14. Reservation Summary
Wisdom may generate a Reserve Summary to facilitate the understanding of an operation.
This document can visually gather information such as:
Contracted service.
Professional.
Client.
Service amount.
Service fee.
Payments made.
Refunds.
Related documents.
The Booking Summary is informative and must expressly state this: it is not an invoice for the work nor does it replace legally required invoices. It will separate the amount of the Provider and the Service Fee and will not present Wisdom as the issuer of the entire service.
When there are several documents, they can be downloaded together, preserving the identity and content of each issuer. If the Provider has not yet provided its invoice, its absence will be indicated without generating a substitute.
15. Client tax data
The client may provide or update the tax data necessary for the issuance of their documents.
Changes made after the issuance of an invoice will not automatically modify documents already issued.
When a document already issued contains incorrect data and its correction is legally necessary, the applicable rectification procedure will be used.
The user is responsible for providing true and updated data.
16. VAT, exemptions and other taxes
Each issuer is responsible for the tax treatment of its own operations.
Wisdom will determine and apply the taxes corresponding to the services that it provides in accordance with its tax situation and the applicable regulations.
The professional will be responsible for determining the taxes applicable to their services.
The Service Provider determines and applies the taxes on their invoice using their own means. Under this arrangement, Wisdom does not request tax settings in order to generate invoices on the Service Provider’s behalf.
The information stated or contained in an uploaded file does not constitute validation by Wisdom. The absence of an audit does not exempt the Provider or Wisdom from their respective legal obligations.
17. International operations
Tax obligations may vary depending on the country of establishment of the parties, the location of the service, the business status of the recipient and other circumstances.
Wisdom may adapt the documentation, taxes or information requested when necessary to comply with applicable regulations.
The professional remains responsible for determining his or her own international tax obligations where applicable.
18. Currency
Invoices and documents linked to a reservation will reflect the currency in which the operation was legally carried out.
Wisdom may display indicative conversions in other currencies to facilitate user understanding.
These conversions do not replace the actual amount of the transaction or the amount reflected in the tax documentation.
19. Premium Billing
When a Premium subscription is charged directly by Wisdom, confirmed charges may generate the corresponding invoice.
Each renewal or independent collection will be documented in accordance with applicable regulations.
No invoice will be issued for failed payment attempts or for operations that have not resulted in a collection.
When Premium is contracted through the App Store and it is Apple who processes and documents the operation, Wisdom will not issue a second invoice presenting itself as the one who has directly made that charge.
20. Conservation and access to documents
Wisdom may retain invoices and other tax documentation for the legally required periods.
Users will be able to access the available documents using the functions enabled in the application.
The conservation of information will continue when it is necessary for tax, accounting, administrative obligations, fraud prevention, disputes or defense of rights, even if an account is subsequently closed.
21. Information to the authorities
Wisdom will comply with the legal information obligations applicable to the platform.
This may include the collection, verification and communication of financial or tax information from certain providers in accordance with standards such as DAC7.
These communications do not mean that Wisdom files the professional's personal tax returns or assumes the payment of their taxes.
22. Fiscal responsibility
Each party is responsible for its own tax obligations.
The Service Provider is responsible for their income, documents, declared data, registrations, taxes and other obligations arising from their activity. Falsehood or non-compliance on their part does not make Wisdom a guarantor of the Service or of their tax situation, without prejudice to Wisdom’s own responsibilities.
The client will be responsible for providing correct information when requesting tax documentation in their name.
Wisdom will be responsible for its own obligations as a platform and the tax documentation that it is legally required to issue.
The use of Wisdom tools does not exempt any party from complying with the regulations that apply to it.
23. Changes to this Policy
Wisdom may modify this Policy to adapt it to legislative, fiscal, technological or functional changes.
When a modification is relevant to users, it will be communicated through the appropriate means.
