Persol Business Process Design just rolled out Zero Billing, a service that tries to wipe out human labor from billing work by leaning on AI, machine learning, and a mix of automation tools. Billing is one of those annoying back office tasks that spikes at month end, drags teams down, and still depends on people stitching together tools that never talk to each other. Most companies struggle because every client has its own rules and formats, which leaves teams drowning in manual checks.
Zero Billing tackles that mess by automating invoice creation, invoice intake, contract checks, and workflow approvals. The pitch is straightforward. Let AI read free text instructions, calculate deadlines, match contract terms, and keep the data flowing without the usual hand holding. Early results show roughly an 80 percent cut in labor hours for invoice issuance, which tells you how much waste was hiding in the old process.
