Why valorización contratista cycles eat your cash

The cycle

Valorización contratista is the monthly invoice the contractor submits to the client for work performed. Under EPC, the cycle binds three things tightly: the avance physical (what got built), the dotación headcount (who was on-site), and the client's accepted format (Power BI / SAP IDoc / Excel template / custom XML).

When any of those three drift out of sync, the cycle slips. A slipped cycle moves the invoice from month-N to month-N+1 — and the contractor finances the gap.

Where the slip happens

In our deployments at CUMBRA Quellaveco, COSAPI San Gabriel, and similar projects we observed the same pattern: 60–70% of valorization slip is mapping work. The avance is correct, the dotación is correct, but converting them into the client's exact format took 3–5 days of manual reconciliation per cycle.

That's a 3–5 day delay on cash multiplied by the contract size. For a USD 4M / month operation, that's roughly USD 600,000–1,000,000 of working capital permanently absorbed in the timing gap.

What custom mapping fixes

A custom mapping layer — one that knows your protocols and the client's expected schema — turns the manual reconciliation into a query. The avance and dotación data already live in your roster and project-tracking systems. The mapping translates them at submit time.

In CUMBRA's deployment we measured the cycle from > 5 days down to < 24 hours. That's not a feature; it's working capital recovered.
