The customer said go ahead, out loud. Who remembers at invoice time?

For example: Your tech finds more work behind the wall, and the customer says go ahead, out loud.

What it costs

At invoice time, nobody remembers who agreed to what.

What owners do today

A phone call to the office and a note that never makes it to the invoice.

Stop before the extra work starts

A spoken yes is real in the moment and gone by the time the invoice arrives. Make it a rule for the whole crew: when the work grows past the estimate, stop and write it down before the tools come out.

Write down five things

Each change, however small, gets the same short record:

  • What was found, in plain words, with a photo when you can.
  • Why it needs doing, and what happens if it is left.
  • What it adds to the price, and to the time on site.
  • Who said yes, and when.
  • Who on your side approved the price.

Get the customer's yes in writing

Send the change to the customer and ask them to reply yes in writing: an email reply or a signature on the page both work. Keep that reply with the job. It ends the argument before it starts.

Put it on the invoice as its own line

List each change separately on the invoice, in the same words you used when the customer agreed. The customer recognizes their own yes, and the original price stays the price they were quoted.

Work that comes off the job gets the same treatment, so the customer sees the credit too.

Say it before the job starts

One line on every estimate sets the rule for both sides: anything found once the work is open is priced and agreed before it is done. Nobody is surprised, because nobody was told otherwise.

    Change order CO-2026-03 on the CONSTRUKTR web dashboard for the demo company, waiting for a decision: extend the Wing C patch and reseal about 20 feet of open parapet coping, raised by Danny Ortiz on Sep 30, 2026, because the coping is open and letting water behind the membrane. It adds $2,150.00, taking the recorded price of $1,650.00 to $3,800.00, with Approve, Send to customer, Have the customer sign and Reject buttons.

Questions owners ask

Will asking for a signature slow the job down?

Very little. A one-line written yes is a record, and it is quicker than an argument at invoice time.

What if the customer will not agree in writing?

Make anything unsafe safe first, such as an active leak or a live wire. Then stop, finish what was quoted, and price the rest as its own job.

Can software keep this record?

Yes, on your side. CONSTRUKTR's change orders come with every plan: a tech raises the added scope from the job, the office prices it and approves it, and the record keeps who approved what. The customer's own yes is still yours to get, by email or on paper.
