I have agreed to pay for a car repair. how to protect myself from additional costs?

I bumped into another car when reversing. I have offered to pay the cost of repair. How can I protect myself from further costs? Should I write a statement and ask the other party to sign it? How should I word it? Is the invoice sufficient?
