What you get

Why builders choose EstiMate

Price the change where it happens

Materials and labour for the variation, a title and a note, sent from the phone while you're stood in front of it. The client gets a link, sees the price and approves or declines.

  • Materials + labour costing
  • Client approval link
  • Approved / declined / pending status

Everything downstream updates

An approved variation joins the job's value: the contract total, the client's total owed, the invoice ledger, Cost control, Business, Reports and the year-end all move together.

  • Contract addendum
  • Invoice on approval
  • Reports include extras

Upsells the client picks

Optional extras on the original quote — the bigger skylight, the smart thermostat — are ticked by the client on the quote link and recorded as approved additional works when they accept.

  • Client-selectable extras
  • Live total on the quote
  • Choices locked on acceptance

No more 'we agreed that on site'

Each variation has a number, a date, who approved it and what it cost. When the final account is discussed, the list is the answer.

  • Variation numbers
  • Timestamps
  • Client responses recorded

Questions

Frequently asked questions

How does the client approve a variation?

They open the link you send (WhatsApp or email), see the description and price, and tap Approve. The response is recorded on the job with the time.

Does an approved variation change the contract?

Yes — it's added to the contract total as an addendum, and to the amount the client owes, invoices and all reports.

Can I record a variation the client agreed verbally?

Yes, mark it approved yourself; the record still shows the price, date and who marked it. Sending the link is better evidence.

Is this on the free plan?

Additional works are part of the EstiMate plan (£15.99 a month) and above.
