Most builders can tell you about a variation that got away. The client asked for something extra while walking the site. The supervisor agreed, because it was a reasonable request and the relationship was good. The work was done, the extra materials went on the job and the extra hours went on the timesheets. But nobody raised an invoice for it, because by the time the office prepared the final claim, nobody remembered that it had been a change to the contract.
One missed variation is annoying. Spread across every job and every supervisor over a year, it can be the difference between a good year and a flat one.
Why variations get lost
Variations are usually lost at the moment they are agreed, not at the moment they should be invoiced. The conversation happens on site with no paperwork within reach. The supervisor is thinking about getting the job done. By the time they are back in the ute, the change has joined a mental list of things to mention to the office, and that list gets shorter on the drive home.
The second place they get lost is pricing. A variation scribbled in a notebook still needs to be costed, sent to the client and approved before the work starts. If that takes three days and the client wants an answer now, the supervisor gives one and the formal process gets skipped. Once the work is under way, the leverage to get a signature has gone.
The third is the final claim. If the person preparing it is working from the original contract and a folder of emails, any variation that was agreed verbally is invisible to them. They are not being careless. They cannot invoice something they do not know about.
What helps straight away
- Nothing changes without a number. Every variation gets a sequential number as soon as it is raised, even if the price comes later. A numbered list is something the office can check against the final claim.
- A simple variation form on the phone. A photo, a description, a rough price and the client's name. A shared form in a notes app will do, as long as the supervisor can fill it in on site in a couple of minutes.
- A weekly variation review. Ten minutes with each supervisor going through the open list. Has the client approved it? Has the work been done? Has it been claimed?
What a proper variation workflow looks like
Builders who have stopped losing variations have made the right way to raise one also the easiest way. The supervisor raises the variation on their phone while they are standing on site, with photos. The office prices it from the same catalogue the original estimate came from, so it takes minutes rather than days. The client gets a document they can approve from their phone. Once it is approved, the variation sits on the job next to the contract, and the progress claims and the final claim pick it up without anyone having to remember.
That is how variations work in JACK, the construction platform we built with a builder. Variations, selections and progress all live on the job, the mobile apps work on site without reception, and the financial tracking and cashflow forecast update as each variation is approved.
If your business runs jobs across spreadsheets, email and goodwill, the variation workflow is often the best first piece to build. It pays for itself quickly, supervisors see the benefit straight away, and estimating, claims and job costing can be connected to it later.
