What you get

Why builders choose EstiMate

From accepted quote to signed contract

When the client accepts, the contract is built from the quote: scope, price, deposit and stage payments, programme dates. Your standard terms are filled in from Settings and can be edited per job.

  • Payment terms and late payment
  • Delays and weather
  • Responsibilities, insurance, guarantee, disputes

E-signature that stands up

The client reviews the contract on the quote link, types their name to sign, and the signed date and name are recorded. Both sides download the PDF. No printing, no scanning, no 'I never saw that'.

  • Signed online, timestamped
  • PDF for both parties
  • Contract locks the scope

Variations as signed addenda

Every approved variation is added to the contract total with its own approval record, so the final account is the contract plus a list of signed changes — not an argument.

  • One-tap approval link
  • Contract total updates
  • Full audit trail

Consumer-friendly and clear

Written in plain English for domestic clients, with the cancellation and deposit terms UK consumer law expects, and a legal toolkit for when things go wrong: letters before claim, suspension notices and statutory interest.

  • Plain-English terms
  • Cooling-off wording
  • Legal toolkit included

Questions

Frequently asked questions

Is an e-signed contract legally binding in the UK?

Electronic signatures are recognised under UK law and are widely used for building contracts. EstiMate records who signed, when, and the exact document, which is the evidence that matters.

Can I use my own terms?

Yes. Your default payment, delay, responsibility, insurance, guarantee, termination and dispute wording is set once in Settings and pre-filled on every contract; edit any clause per job.

Is it a JCT contract?

EstiMate's contract is a plain-English build contract generated from your quote. For projects that require a formal JCT or NEC form, attach the signed form to the job's documents and use EstiMate for valuations, variations and records.

Which plan includes contracts?

EstiMate (£15.99 a month) and above.
