Renovations run over budget in small steps, not in one bang. Log every stage payment and purchase next to your contract sum, with extras from the extras log counted in automatically, and see where you stand before the final invoices arrive. Free, on your own device.
Pay per completed stage, keep the deposit small, and hold the final instalment until after a good handover; the full logic is in how to pay for a renovation. Extras deserve their own discipline: log them as they happen and they can never surprise you here. Still planning? The budget planner is the before-quotes version of this page.
A spending tracker for during the build: your real payments against the contract sum, with extras from the extras log counted in automatically so overspend shows early.
What you enter: Your contract sum and your payments. What you get: A running view of spent versus agreed, on your own device.
The budget planner divides a budget before quotes arrive: how much to which part of the project. This tracker starts when the build starts: every payment and purchase against the contract sum, with your extras counted in automatically. Planning first, tracking during; two different questions.
Because the last weeks of a build are the most expensive: the final instalment, the snagging, the items everyone postponed. If you are at 90 percent before handover, you arrive at the moment you most need a reserve without one. Keep 10 percent for the unexpected until the work is signed off.
