Keep the original scope

Scenario price
$400.00
Payment fee
$12.30
Known labor (6.00 h)
$180.00
Tools, acquisition, overhead
$10.00

Before tax, refunds, and costs not entered. One combined payment assumed. Fees and time values are illustrative, not provider rates or earnings forecasts.

02 / Adjust the assumptions

Zero acquisition and overhead are explicit starting estimates. Enter them if they apply. Time is rounded to the nearest minute.

03 / What would keep the original estimate?

These minimum extra prices cover the added time and percentage fee under your assumptions. They preserve the original contribution even if it is negative; they are not suggested quotes.

Integration only
$92.78
Integration + entered support allowance
$216.49

Same tools and overhead; one combined payment. Unlimited support remains unknown. Unavailable means the fee or the tool’s amount limit prevents a modeled solution.
