Why Project Managers Hate Coding Invoices — and What It Costs You | Tanmaya Kala (TK), Co-Founder & COO, MeltPlan

Tanmaya "TK" Kala spent 13 years at DPR Construction rising to Project Executive on billion-dollar healthcare projects — including OSHPD hospital builds where clients demanded actual-cost documentation down to the square foot of drywall. Now he's Co-Founder & COO of MeltPlan, building AI tools for pre-construction.

In this episode of Finance at the Jobsite, TK breaks down why the finance–operations gap exists on nearly every project: why coding invoices is "a chore" that gets deprioritized, how he blocked Friday afternoons just to get billing done, and why the accounting system — not the PM platform — is still the real source of truth. He shares stories from the field, including a subcontractor emailing certified payroll with exposed Social Security numbers, and explains why billing becomes a last-minute scramble when everyone waits until the deadline to maximize cash flow.

We also cover: lump sum vs. cost plus contracts and what each means for financial workload, why only 2% of projects hit cost, time, and benefits, material tracking in a post-COVID supply chain, and TK's vision for AI making project managers reviewers instead of doers — plus his 95% accuracy threshold for when AI automation actually pays off.
