Is a quote legally binding? Guide for freelancers

Yes: a quote can be legally binding once a valid contract exists — usually through offer and acceptance under Dutch law (Civil Code book 6). A signature is not always required; acceptance by email or via Moneybird’s online accept flow can count. Whether you or your client are bound depends on what the quote says (for example “without obligation”), whether the offer was revocable, and whether the validity date has passed. This article explains that at a general level — not legal advice — and what to do when the client has not replied yet.

Offer, acceptance and when you have a contract

Under Dutch contract law, an agreement is formed by offer and acceptance (Article 6:217 DCC). Your estimate is often the offer: work, price and terms. The client accepts by saying yes, signing, accepting online or confirming in writing — as long as it is clear and aimed at that offer.

Not every quote is immediately set in stone. Article 6:219 DCC distinguishes revocable and irrevocable offers. You can usually withdraw a revocable offer before acceptance (unless you promised otherwise). An irrevocable offer binds you even before acceptance: you cannot simply take it back. What applies in practice depends on the text on the quote, your emails and what parties may reasonably expect.

Is a quote legally binding without a signature?

Often yes, if acceptance is clear. A signature is useful evidence, but Dutch law does not require a wet signature for every business quote. Acceptance by email (“agreed to quote 2026-042”), a confirmation that names scope and amount, or accepting in the Moneybird portal can be acceptance — if it is unambiguous.

Without a signature, proving what was agreed can be harder. Many freelancers therefore:

• repeat quote number and amount in every email;
• use Moneybird online acceptance where available;
• send a short confirmation after verbal yes: “as discussed, agreed to quote X for €Y”.

Is email acceptance enough?

Email is a normal way to communicate and to accept. It must be clear: the client must recognise and accept the offer. Vague lines (“sounds good, let’s talk next week”) are riskier than “I agree to quote 1234 of 12 October, including planning as described”.

You can tighten the process:

1. Send the estimate through Moneybird with link or attachment.
2. Ask explicitly for confirmation on the quote (email or portal).
3. Put verbal agreement in writing the same day.

See estimate follow-up for rhythm before and after that confirmation.

Non-binding (“vrijblijvend”) versus firm quotes

Many Dutch quotes say vrijblijvend (without obligation). That does not automatically mean “legally worthless”, but often means the supplier may withdraw right after acceptance where the law or your terms allow (Article 6:219(2) DCC: with a non-binding offer the supplier may still withdraw immediately after acceptance). Without that wording, and with an irrevocable offer, you as supplier are bound sooner once the client wants to accept.

For the client: without acceptance there is usually no contract to perform. “We are still thinking” is not acceptance.

When are you bound as the freelancer?

You are bound to an irrevocable offer that the client accepts in time — or to an accepted quote where you cannot rely on the vrijblijvend withdrawal rule. You are less locked in when:

• the client has not accepted yet;
• the validity period has ended and you did not extend;
• you revoked a revocable offer before acceptance and made that clear.

Consumer law and sector rules can add layers; this article does not cover every edge case.

When is the client bound?

For the client, acceptance is usually when the agreement kicks in. Until then they can often still walk away without a contract — though it may be awkward socially. After acceptance, performance, extra work and cancellation follow your quote, terms and law.

A signed quote is strong evidence, not the only form of acceptance.

Validity and binding status

Binding status and validity are related but not identical. The “valid until” date says: this offer holds until then (price, planning). After that you may send a new quote. Whether an old quote can still be accepted depends on what you communicated; see quote validity in Moneybird.

Align follow-up with that date: remind calmly before expiry so the client can decide while the offer is current.

No response yet: not binding, still follow up

Without acceptance there is usually no contract — but you still want clarity. Send a short follow-up email, call if that fits your quote follow-up call approach, and mention validity. If it stays quiet after your last touch, close the estimate professionally (estimate no response).

Moneybird does not send automatic estimate reminders like invoices. FollowBird connects to Moneybird, shows open estimates in your dashboard and sends up to 3 email reminders on days you set; when the estimate is accepted in Moneybird, reminders stop. FollowBird does not call clients and does not judge whether a quote is legally binding — it helps you ask for a clear yes or no in time.

Checklist before you become bound

• Does the quote say vrijblijvend and valid until?
• Online acceptance in Moneybird or explicit email?
• Terms attached or linked?
• Plan for verbal yes (confirmation email)?
• Follow-up scheduled before expiry?

Not legal advice

This article is not legal advice. Rules on offer, acceptance, consumers and cancellation vary by situation. For large amounts, disputes or consumer clients, have your texts and process reviewed by a lawyer. FollowBird supports follow-up on open Moneybird estimates, not contract advice.

Summary

Is a quote legally binding? When there is a valid agreement — typically offer plus acceptance. Signatures help but are not always required; email and portal can suffice. “Vrijblijvend” and validity shape how firm both sides are. Until there is a yes: follow up professionally.
