The VariationFlow app
With the app, anyone on site records a variation: what changed, who directed it and their signature, photos, a voice note and the location. In about a minute, with or without signal, and in your crew’s own language.
Free for iPhone and Android. Your crew signs in with your company’s VariationFlow account, and the account is free for your first job: one project, two users, no card.

A variation recorded on the day, with a photo, a location and the name of whoever directed it, carries more weight in a progress claim, or an adjudication, than anything pieced together from memory.
Pick the project, say what changed and who directed it, and hand over the phone for their signature. The location comes from GPS, or type a room or grid reference over it. Add photos and a voice note of up to 30 seconds.
Switch on “Work has proceeded” when work started without a written direction. The app shows a commercial risk warning, and the variation reaches the office flagged that way.
Before sending, the app checks it can reach VariationFlow rather than trusting the phone’s network status. With no connection it keeps the record on the phone, photos and voice note included, and sends it by itself when signal returns.
Every record carries its own key, so a second attempt to send never makes a duplicate, and it keeps the time it was taken, not the time the signal came back.
The register lists your variations by reference, with their status from Priced and Submitted to Instructed and Paid, and who directed each one. Anything still waiting after 28 days is flagged, and turns red after 42.
The app speaks the phone’s language: English, Spanish, Italian, Portuguese, Japanese and five more. Amounts are in your company’s currency, Australian dollars, and site staff see no prices.
A record lands as a draft in the register on the web, ready to price and submit to the head contractor, and anyone with the dashboard open sees a notice the moment one comes in from site.
