Variations, that won't get knocked at final accounts

Log them when they're instructed, price based on the terms set in your contract and carry the approved ones into the live bill and the next valuation.

How much unapproved work are you carrying?

Instructed work isn't priced

Work is verbally confirmed on site. The work starts, the pricing follows weeks later, and by then the evidence has gone.

Nobody tracks the unapproved ones

Six variations sitting unapproved is a real margin risk. The work was instructed verbally but never confirmed in writing only to be negotiated at final accounts.

Unrecovered variations

Work done this period misses the next application, pushing payment back 60–90 days.

See how growing contractors are using Coreloops to track and recover variations.

Draft, sent, approved or rejected

Track each variation through its status with the date it was raised and how long it's been open. Additions, omissions and modifications are handled separately, with cost and sell held against each.
