Construction Site Billing

Hello, I'm in need of assistance with the billing of a residential construction project I'm undertaking. I require detailed cost breakdowns for each task and phase, to ensure all expenses are accounted for. I have specific billing software and methods that I would like used, so I'm looking for someone who is experienced in using them. The project is currently in its early stages, so time is of the essence! If you have the required expertise, I invite you to submit your proposal for this project. Thank you.
