Most cost overruns on Nigerian sites don't come from one big theft — they come from dozens of small, inflated quotes that never get checked against what materials actually cost nearby. Costra closes that gap before the money moves, not after.

How a request moves through Costra

REQUEST LOGGED

Site sends a quote

Material, quantity, supplier, and the price quoted — logged in one place instead of scattered across calls and WhatsApp.

CHECKED AGAINST FLOOR

Costra checks the floor

Compared against verified prices Costra collects directly from independent suppliers at Dei-Dei and Mararaba — never from the requests being checked.

YOU DECIDE

Approve or push back

You see exactly how a quote compares before you release a naira. Every decision is recorded in a defensible audit log.

What you get on day one

Budget vs. actual

See what's approved through Costra against your budget, stage by stage.

Audit log

Every request, check, and decision recorded — your defensible record if anyone asks.

Independent market floor

Reference prices sourced only from independent suppliers, never from submitted quotes.

Self-reported spend

Purchases made outside Costra are tracked separately, never mixed with verified spend.

Coming after Phase 1

Built once the verification loop is proven

Quantity-vs-plan flagging, reorder reminders, a verified project timeline, and BOQ-based budgeting — earned by real transaction history, not shipped ahead of it.
