How to keep track of renovation costs
Renovation costs spiral quickly without a system. Learn how to track invoices, catch early-payment discounts, and keep your budget under control.
Three contractors, five invoices, one nearly missed payment. Without a system, renovation costs spiral out of control fast. Here is how to stay on top of them.
Why costs get confusing quickly
Different trades invoice at different times, in different formats, with different payment terms. Advance payments arrive before work is complete; final invoices come months later. Without a clear record, you lose track of what is paid, what is outstanding, and what is overdue.
The four budget categories
- Labour – all contractors, including travel and hourly surcharges
- Materials – sometimes bundled in quotes, sometimes invoiced separately
- Planning – architect, structural engineer, permits
- Contingency – 10–20 % of the total budget for unexpected issues
Early payment discounts: easy savings
Example calculation
Many invoices include a 2 % discount for payment within 14 days. On a €50,000 project, that is €1,000 left on the table if you miss the deadline. Worth tracking.
How to stay in control
- 1Record every invoice immediately: amount, date, trade, payment status.
- 2Separate advance payments from final invoices – they relate to the same work.
- 3Make early-payment deadlines visible.
- 4Monthly review: paid / outstanding / under review.
