Why Marine Contractors Fund the Barge Before the Check

QUICK ANSWER

Marine contractors fund the barge before the check when mobilizing equipment on water costs a fortune weeks ahead of the first pay application, port authorities pay on government cycles, and every project demands its own bonding documentation. One $13.5M marine contractor doubled net profit from 7% to 14% on the CONTROL system.

THE CASH PROBLEMS

The specific ways marine contractors lose cash, pulled straight from what makes this trade different.

Port Authority Pay Cycles

Ports and government owners pay on their process, which routinely runs 60 to 90 days behind the work. Your barge charter and crew boat run on 30-day terms.

Barge Mobilization Recovery

Floating equipment to the job is one of the largest costs in the trade, and it earns nothing by itself. Mob and demob priced as their own lines keep the project paying for its own logistics.

Per-Project Bonding Documentation

Every marine project wants fresh financials, WIP schedules, and bonding paperwork. Clean monthly statements turn bonding from a fire drill into a formality.

International Vendor Payments

Specialty marine gear and parts often come from overseas vendors on wire terms. Currency timing and prepayment belong inside the cash forecast.

QUESTIONS MARINE CONTRACTORS ASK
Why do marine contractors run out of cash on government work?
Marine contractors run out of cash on government work because port authorities and agencies pay on 60 to 90 day cycles while barge charters, fuel, and crews get paid monthly or weekly. Mobilization costs stack on top, spent weeks before the first application. The margin can be excellent while the account runs empty.
How does a marine contractor keep bonding capacity ready?
A marine contractor keeps bonding ready with clean monthly financial statements, an accurate WIP schedule, and a balance sheet the surety can trust. Chapter 7 of CONTROL builds that monthly cadence, which is how one $13.5M marine contractor kept its bank balance above $1.2M and its surety comfortable.
What profit margin should a marine contractor target?
A marine contractor should target 22 to 30% gross profit per project and 12% net profit after all expenses, with overhead between 9 and 13%. One $13.5M marine contractor moved from 7% to 14% net once equipment cost basis, billing standards, and a monthly cadence were in place.
