What is a Running Bill (RA Bill) in Construction?
A Running Bill, commonly known as RA Bill, is a periodic invoice submitted by the contractor to the client or department for the work executed during a specific period (usually monthly). It is an interim payment request for the progressive work done on the project.
RA Bill helps contractors recover costs of labour, materials, and machinery on an ongoing basis instead of waiting until project completion.

- Helps clients monitor project progress
- Reduces financial burden on contractors
- Creates transparent payment records
- Supports better project control and decision-making
Proper RA Bill management is a key factor during prequalification in construction tender in India.
