  • Electronic signatures on commercial quotes are legally valid in the UK under the Electronic Communications Act 2000 and retained UK eIDAS regulation.
  • A simple or advanced electronic signature is sufficient for most B2B quotes; qualified signatures are only needed when the document must carry the legal weight of a deed.
  • The audit trail - capturing timestamp, IP address, signer email, and document version - is what makes an electronically signed quote defensible if the order is later disputed.
  • Configuring the post-acceptance trigger is as important as the signature field itself: accepted quotes should convert to job records automatically, not after someone checks the inbox.
  • Quotes accepted within the same working session as they are sent convert at significantly higher rates than those that cross the end-of-day boundary.

A commercial quote can be accepted electronically in the UK under existing legislation, and the signing experience takes the customer under two minutes. This guide covers the setup sequence: signature fields, audit trail configuration, and the post-acceptance trigger that moves the job into your pipeline the moment a customer confirms.

A customer in the UK can legally accept a commercial quote with an electronic signature. Under the Electronic Communications Act 2000 and the retained UK eIDAS regulation - which continues to apply post-Brexit - an electronic signature is valid provided it demonstrates the signer's intent and is uniquely linked to them. For most commercial quotes, from supply agreements and project proposals to service contracts and product orders, a simple or advanced electronic signature is sufficient. No printing, no wet ink, no scanning. From the customer's side, the process takes under two minutes: they receive a secure link, read through the quote, click into a clearly marked signature field, type or draw their signature, and receive a confirmation email with the signed document attached. That is the complete customer journey.

Why the print-sign-scan cycle costs more than it looks

The gap between a customer deciding to go ahead and the formal confirmation that puts the job in motion is where deals go quiet. A buyer who opens a quote, decides they want to proceed, and then cannot immediately confirm because they need to print, sign by hand, scan, and email back will often save the email to deal with later. Later rarely carries the same urgency. Research on B2B quote-to-order conversion rates published in 2026 found that the average across industries sits at 20 to 35%, and a key operational factor separating top-performing businesses from the rest is how easy the quote is to accept - not just how fast it arrives. Quotes accepted within the same working session as they are sent convert at significantly higher rates than those crossing the end-of-day boundary.

An eSignature field removes the mechanical barrier. A customer ready to say yes can confirm in the same browser session, without locating a printer or finding a scanner. The thesis of this guide is that setting up eSignature on a quote is not a single configuration step - it is a short sequence of decisions covering the signature field itself, the audit trail that makes it legally defensible, and what happens in your system the moment acceptance lands.

The configuration sequence

1

Check that your quote template includes a signature block

Before enabling eSignature, you need a quote template that has a dedicated signature block - a clearly marked section at the base of the document where the customer's name, company name, date of signing, and the signature itself will appear. Without a signature block, there is nowhere for the customer to sign, and the eSignature tool has no field to populate. If your current template does not include this, add it in your document template settings before going further. The signature block also signals to the customer that this is the formal acceptance point, not simply a pricing summary or a proposal for discussion.

2

Decide which level of electronic signature your quotes require

Under UK eIDAS, three levels of electronic signature are recognized: simple, advanced, and qualified. For most commercial quotes - services, goods, project work - a simple or advanced electronic signature is legally sufficient. A simple electronic signature, such as a typed name or a drawn signature accompanied by a declaration of agreement, meets the requirements of the Electronic Communications Act 2000 provided there is a clear record of who signed and when. An advanced electronic signature adds an identity verification step, typically a one-time code sent to the signer's email or mobile number, which links the signature more securely to the named individual. A qualified electronic signature is the highest tier and carries the same legal weight as a handwritten signature in any UK court; it is relevant for transactions that function as deeds rather than simple commercial agreements. The 2019 Law Commission report confirmed that electronic signatures can satisfy statutory signature requirements in the UK, which means that for standard B2B quotes, advanced is the practical default and simple is acceptable for lower-risk transactions.

Add the signature field at the correct position in the template

Place the signature field after the pricing summary and payment terms, and before any footer or contact section. The field should capture at minimum: the signer's full name, their job title if the quote is addressed to a company, the date, and the signature itself. If your quote includes binding terms and conditions, add a checkbox above the signature field with a statement such as "By signing below, I confirm that I have read and agree to the terms set out in this quote." This checkbox creates the explicit consent record that makes the electronic acceptance defensible - it is the evidence that the signer read the terms and actively agreed, rather than simply clicking through a form.

4

Configure what happens the moment the quote is accepted

This is the step most businesses skip, and it is the one that determines whether eSignature actually changes how fast jobs start moving. When a customer signs, something should happen automatically in your system - not after a team member notices the email. At minimum, the accepted quote should convert into a confirmed order or job record, the account manager or operations team should receive a notification, and the quote should lock against further edits so the signed version cannot be inadvertently changed. When post-acceptance automation is not configured, the team learns about accepted quotes by checking inboxes, which reintroduces the manual delay that eSignature was supposed to eliminate. Set these triggers up before you send the first eSignature-enabled quote.

5

Confirm your audit trail captures the required data points

An audit trail is what makes an electronically signed quote legally defensible if the order is later disputed. It should record: the timestamp of when the document was opened, the timestamp of when the signature was applied, the signer's email address, their IP address, and the precise version of the document that was signed. Most eSignature platforms generate this record automatically and attach a certificate of completion to the signed PDF. Check that your setup captures all five data points and that the signed document and its audit record are stored together in one retrievable location. Keeping the signed PDF in email and the audit log in a separate system creates retrieval problems if you need to produce the evidence quickly - for example, when a customer later claims they agreed to different terms.

Version the document before sending

Lock the quote from editing the moment it is sent for signature. If the pricing changes before the customer signs, withdraw the quote and reissue rather than editing the live document. Editing a document after it has been opened for signature creates version inconsistencies that the audit trail will record - and which a customer could use to question whether they signed the version they reviewed.

Testing and sending

6

Walk through the acceptance process from the customer's side

Before enabling eSignature for live quotes, send a test version to your own email address and complete the process as a customer would. Open the link, read through the document, locate the signature field, sign, and submit. Check that the confirmation email arrives within seconds, that it contains the signed PDF as an attachment, and that the post-acceptance trigger from Step 4 fires correctly. Confirm that the audit trail records the opening and signing events. A broken link, a delayed confirmation, or a trigger that does not fire are easy to catch in testing and very visible to a customer who has just committed to an order. Any friction at the point of confirmation signals to the customer that the business is not organized, which is the wrong message to send immediately after they have agreed to spend money.

7

Include clear acceptance instructions in the message you send with the quote

The most technically correct eSignature setup will underperform if the customer does not understand what they are being asked to do. Include a short, specific instruction in the cover message: "To confirm this order, open the link below, review the quote, and sign at the bottom of the document. You will receive a signed copy by email immediately." Brief instructions reduce the chance that the recipient forwards the email to a colleague without context, loses the link, or assumes someone else is responsible for confirming. For larger orders where internal approval is involved, a short call after sending helps confirm the right person has access to the signing link. The approvals feature can surface quotes that have been opened but not yet signed, giving you a factual basis for follow-up without guessing.

Multiple signers

If your quote requires sign-off from more than one person at the customer's organization - for example, a budget holder and a technical lead - configure the signing order before sending. Most eSignature tools allow you to specify a sequence, so the second signer only receives the link after the first has signed. This prevents a situation where two signers receive the quote simultaneously, one signs, and the other never acts on it.

When the setup is working

When the configuration runs correctly, the sequence closes without manual intervention: quote sent, customer signs, job confirmed, team notified, customer receives their signed copy. The paperwork gap disappears. For the customer, acceptance feels as straightforward as placing an online order. For the business, same-day acceptance becomes the operational norm rather than the exception that requires a chasing call. The audit trail and post-acceptance triggers handle the administrative record that the print-sign-scan cycle used to leave to chance - and left, more often than not, incomplete.
