Why signature-ready proposals still get delayed

A proposal may be complete, internally approved, and already in the customer’s inbox, yet acceptance can still take time. The delay is often caused not by ongoing negotiations but by the process itself: the PDF must be downloaded, printed, signed, scanned, and returned. Alternatively, the customer sends an informal acceptance by email, which someone must later assign manually to the correct opportunity.

These interruptions extend the sales process and make follow-up more difficult. Sales representatives may not know whether the document has been opened, who is expected to sign, or whether an additional customer-side approval is missing. Multiple files with similar names also create uncertainty about which version is current.

An electronic signature workflow brings these steps together. The recipient opens a link, reviews the proposal, and signs on a phone, tablet, or computer. The completed document is then distributed to the designated participants and assigned to the relevant record.

Electronic signatures do not make customers decide faster. They do, however, remove avoidable technical and organisational barriers once a decision has been made.

Clarify what acceptance means before adding signatures

Not every proposal requires a signature to be accepted. Depending on the applicable law, type of contract, agreed terms, and circumstances, an explicit email or conduct indicating acceptance may be relevant. Other transactions may be subject to statutory or contractually agreed form requirements.

Before digitising the process, clarify:

• Does the signature conclude a contract or merely confirm an order?
• Are there statutory, sector-specific, or agreed form requirements?
• Is the correct person signing, and do they have sufficient authority?
• Must terms and conditions, specifications, or other attachments be incorporated?
• Is a particular signing order required for multiple parties?

The answers determine which signature method and workflow are appropriate. Transactions with significant legal or commercial consequences may require professional review of the specific setup. A signature platform does not replace an assessment of the individual case.

SES, AES, or QES: choosing the appropriate level

The eIDAS Regulation distinguishes between simple, advanced, and qualified electronic signatures. Higher signature levels generally involve more demanding requirements for identification, technical safeguards, and signature creation. Using the most complex method for every proposal is therefore not necessarily appropriate.

Simple electronic signature (SES): This category can include a typed name, a confirmation click, or a signature captured within a documented process. It is often suitable for routine, lower-risk transactions without specific form requirements.

Advanced electronic signature (AES): An AES must, among other requirements, be uniquely linked to the signatory, enable identification of the signatory, and make subsequent changes to the signed data detectable. It provides a higher level of technical traceability.

Qualified electronic signature (QES): A QES is based on a qualified certificate and created using a qualified electronic signature creation device. Under eIDAS, it has the equivalent legal effect of a handwritten signature throughout the EU. Issuing the relevant certificate requires identity verification.

Article 25 of eIDAS also states that an electronic signature must not be denied legal effect or admissibility as evidence solely because it is electronic or does not meet the requirements of a QES. This does not mean that every signature has the same evidential weight or satisfies every form requirement.

For typical sales proposals without a specific form requirement, an SES or AES may be suitable. The choice should reflect the risk profile, contract value, potential consequences of a dispute, identification needs, and internal policies.

Building an end-to-end proposal workflow

An efficient process does not begin with the signature field. It connects proposal generation, internal approval, delivery, signing, and storage.

A typical workflow may include:

1. Generate the proposal from structured data: Customer details, items, prices, and contract periods are taken from a CRM, ERP system, or approved template.
2. Trigger internal approval: Discounts or non-standard terms are reviewed by the responsible person before the document is sent.
3. Define signatories: Names, email addresses, roles, and the signing order are specified.
4. Send the document: The customer receives an individual link, a clear request for action, and the details of an accessible contact person.
5. Send reminders automatically: If the document remains unsigned, the system sends reminders at appropriate intervals without creating unnecessary pressure.
6. Document completion: The signed PDF, signature data, and any validation report are assigned to the relevant record in a way that protects their integrity.
7. Start downstream processes: The CRM status, order creation, project handover, or invoicing process is updated or initiated.

Maintaining one unambiguous version is essential. If the price or scope changes after the proposal has been sent, a new version should be created and submitted for signature. Altering a signed document afterwards compromises its integrity.

Practical example: a proposal with two approval stages

An IT service provider prepares a proposal for an implementation project. Any discount above an internally defined threshold requires approval from the head of sales. On the customer side, the project owner should review the document before an authorised representative signs it.

The digital process could work as follows:

• The CRM generates the proposal from approved line items.
• A non-standard discount automatically triggers internal approval.
• Once approved, the customer’s project owner receives a review link.
• The signature request is then forwarded to the authorised representative.
• After completion, both parties receive the same signed PDF.
• The CRM status changes to “accepted”, and a project handover record is created.

The time saving does not come only from the signature itself. Manual status enquiries, file storage tasks, and transfers between systems are also reduced.

User experience affects completion speed

Even a technically secure process may fail if recipients find it confusing. Clear user guidance reduces questions and errors.

A well-designed request should provide the following:

• The sender and purpose of the request are immediately recognisable.
• The proposal can be read on mobile devices without installing software.
• Required fields and signature fields are clearly marked.
• Attachments and incorporated terms are available before signing.
• The recipient can download the document and access it again after completion.
• In multi-party workflows, recipients can see when their action is required.
• A named contact is available for technical or commercial questions.

Additional identification steps should be applied according to risk. An unnecessarily complex process increases friction, while a process that is too weak may not provide the intended level of evidence.

Audit trails, timestamps, and document integrity

For later verification, the process should capture more than a visible image of a signature. Depending on the solution, events such as sending, access, authentication, consent, and completion can be recorded. An audit trail can support the evidential record, but it is not automatically an electronic signature itself and does not remove the need to assess evidential weight.

Technical validation features can indicate whether a PDF was changed after signing. Electronic timestamps can additionally provide evidence that specific data existed at a particular time. Whether a simple or qualified electronic timestamp is appropriate depends on the use case.

Operationally, the following aspects are particularly relevant:

• a clear link between the document version and signature process,
• traceable authentication and consent events,
• protection against undetected modification,
• signed files that remain verifiable over time,
• defined retention and deletion rules.

Addressing GDPR requirements

Digital proposal workflows process personal data such as names, business contact details, IP addresses, authentication data, and event logs. Data protection should therefore be considered during implementation rather than after launch.

Relevant questions include:

• Which data is processed for which purpose?
• What legal basis may apply to each processing activity?
• Does the signature provider act as a processor, and is an appropriate agreement required?
• Which subprocessors are involved?
• Where is data stored and processed?
• Are there transfers to third countries, and on what basis?
• Which access, retention, and deletion rules apply?
• How are data subject requests and security incidents handled?

Only data necessary for the chosen workflow and level of evidence should be collected. Role-based access, multi-factor authentication for administrative accounts, and documented deletion procedures can reduce risk.

Implementation: standardise before automating

A clearly defined initial use case is preferable to an immediate company-wide rollout. A business might begin with standard proposals from one sales team. The existing process should first be documented from drafting through approval and archiving; only then should the organisation decide which steps to automate.

A practical checklist includes:

• classify proposal types and applicable form requirements,
• assign signature levels to defined risk categories,
• document authority and approval rules,
• standardise templates and attachments,
• configure roles and permissions,
• assess CRM, ERP, or document management integrations,
• define reminders and exception handling,
• coordinate data protection, information security, and retention,
• test the process with internal and external users,
• monitor processing time, recurring questions, and error causes.

Electronic signatures shorten the sales process most effectively when they are not treated as an isolated replacement for handwritten signatures. The main benefit comes from an integrated, understandable, and traceable workflow that connects an approved proposal with a properly documented order.
