Self Check-In Opens the Door. When and How Is the Contract Signed?

The access code solves entry. It does not replace the moment when the guest reads and signs the contract for the stay.

A recurring question among short-term rental hosts is simple: if the guest enters alone, when do they sign the contract?

Some hosts email a PDF. Some leave a copy on the table. Others rely on the conditions displayed by the booking platform. When check-in happens in person, the signature may be collected together with the guest's documents.

These answers differ because three separate moments are often mixed together:

• the conditions shown before booking;
• the contract signed during check-in;
• the instructions that physically allow the guest to enter.

Self check-in has automated the third step. It does not remove the first two.

Before booking: information that may affect the decision

Essential conditions should be visible before the guest confirms: price, dates, cancellation terms, material house rules, mandatory charges and relevant property characteristics.

This remains true whether check-in will be online or in person.

Showing conditions before booking, however, does not necessarily mean that the contract governing the stay has already been signed. Pre-contract information and contract execution are connected, but they are not the same operation.

During check-in: the contract needs a defined moment

With in-person check-in, the process is intuitive: the contract is presented, reviewed and signed in front of the host or an authorized operator.

Online check-in should reproduce the same essential step digitally. The correct document must be shown to the guest, linked to the booking and signed through the method used by the check-in process.

A simple "I have read and accept" button can record an acknowledgement, but it should not automatically be described as equivalent to every type of signature. The legal and evidentiary weight depends on the signing method, identification of the signatory, integrity of the document, and how the process is recorded and preserved.

In Italy, rental contracts are subject to a written-form requirement. Electronic documents and signatures can have legal effect, but electronic signatures do not all provide the same level of assurance. Under the eIDAS Regulation, a qualified electronic signature has the equivalent legal effect of a handwritten signature. The appropriate method depends on the contract, the type of operation and professional legal advice.

Readers outside Italy should verify the rules that apply in their own jurisdiction.

A stay under 30 days does not mean "no contract"

A frequent misunderstanding concerns registration.

The Italian Revenue Agency states that rental contracts lasting no more than 30 days are generally not subject to mandatory registration. This does not mean that no contract exists, that form is irrelevant, or that emailing house rules is automatically sufficient.

**Registration, written form and signature are separate issues.**

The property must also keep other obligations separate: guest identification, required authority reporting, tourist tax, statistical reporting and local procedures. The contract does not replace these obligations, and they do not replace the contract.

Why an emailed PDF does not complete the process

Sending a PDF makes the document available. By itself, however, it may not establish:

• which version was presented;
• who signed it;
• when the signature occurred;
• whether the document later changed;
• whether both parties received the complete signed copy.

An orderly process should connect at least five elements:

• 1. the exact document linked to the booking;
• 2. the identity of the signatory;
• 3. the signing action;
• 4. the date and time;
• 5. the signed copy and its audit record.

A timestamp alone does not turn a click into a signature. It is one part of the record, not the entire process.

Online or in person: two paths for the same stay

Properties do not all operate in the same way.

A holiday rental with autonomous access may want the contract and check-in completed before arrival. A small hotel may prefer a signature at reception. A B&B may alternate depending on arrival time or booking type.

A useful system should support both paths.

Online check-in

The guest receives a personal link, completes the required steps, reviews the contract connected to the booking and signs it online. The signed copy is then delivered or made available. Where configured, sensitive access information becomes available only after the required steps have been completed.

In-person check-in

The host or operator opens the booking, presents the contract, collects the signature in person and records the completed step and signed copy within the same booking flow.

The channel changes. The contract and booking remain the same.

Do not hide the contract inside the guest guide

The guest guide and the contract should be connected, but not confused.

The guide explains how to experience the stay: arrival, Wi‑Fi, access, house rules, services and practical information. The contract defines the relationship between the parties and should be clearly presented as a document to review and sign.

Keeping both inside one journey does not turn guide content into an implied contract. It prevents the guest from having to search through separate emails, attachments and links.

The sequence should be clear:

booking → check-in → signed contract → access and stay.

How StayFast Flow is designed to handle it

Flow is the StayFast layer for check-in and stay compliance. Contract signing will be part of the check-in journey rather than a separate emailed attachment.

Two operational paths are planned:

• **online**, with the booking-specific contract presented and signed by the guest during the digital journey;
• **in person**, with the signature collected in front of the host or operator and the signed document recorded against the same booking.

Flow is intended to preserve the relationship between booking, contract version, signatory, date and time, completion status and signed copy. The electronic-signature method and required assurance level will need to match the property's situation and professional advice.

The contract will therefore be an explicit check-in step — not a hidden checkbox and not an implied acceptance inferred from delivery of the door code.

Flow is in development. This section describes the intended direction, not a feature currently available in production.

Where to start

• 1. Have the contract template reviewed for your business and jurisdiction.
• 2. Separate pre-booking conditions from the document to be signed.
• 3. Decide when online signing and in-person signing should be used.
• 4. Do not call a simple click a "signature" unless the process has been designed as one.
• 5. Always connect the contract, signatory, document version and booking.
• 6. Make the signed copy available.
• 7. Keep contract signing, identity checks and regulatory reporting as distinct steps.

The rule that prevents most mistakes

If, after the stay, you cannot reconstruct which contract was signed, by whom, when and for which booking, the process is not complete.

Conclusion

Self check-in does not remove the contract. It moves the point at which the contract must be presented and signed.

The answer is not another PDF inside a message thread. It is a defined signature step, either online or in person, linked to the same booking.

That is where Flow is intended to connect operations and clarity without confusing door access with contract execution.
