Below are common financing structures used by established aerospace businesses. Features vary by lender and market conditions; the points here are educational and general.
SBA 7(a) loan: versatile working capital and growth
The SBA 7(a) program is a widely used option for working capital, equipment, refinancing eligible debt, and even business acquisition. It’s often flexible about use of funds and may suit manufacturers and MROs scaling headcount, inventory, and certifications. Learn more in this in-depth SBA loan guide and the SBA’s official 7(a) overview.
- Typical use cases: payroll and working capital for ramp-ups, tooling and fixtures, refinancing high-cost short-term debt, and partner buyouts.
- Loan sizes: often up to $5 million (subject to SBA rules and lender criteria).
- Helpful when your growth plan includes expanding into new programs, adding shifts, or carrying longer receivables.
For smaller, faster requests, explore the SBA Express loan program for streamlined timelines on reduced amounts.
SBA 504 loan: facilities and major equipment
SBA 504 financing is commonly used for owner-occupied buildings (e.g., hangars, production facilities) and large equipment. A 504 structure pairs a bank first lien with a Certified Development Company (CDC) second lien, often allowing longer amortizations than conventional loans.
- Use cases: hangar or plant purchase/expansion, high-ticket manufacturing and testing systems, energy-efficient upgrades.
- May enable lower down payments versus traditional commercial real estate loans (subject to program rules).
- Fits long-lived assets that generate ROI over time.
Conventional term loans for expansion
Many established aerospace companies use conventional term loans for growth projects: adding lines, consolidating debt, or funding AS9100/ITAR-related investments. Compare structures and documentation differences in this guide to a term loan for small business and review the general features of a Term Loan.
- Use cases: software (PLM/MES/ERP), test benches, additional shifts, and marketing/sales expansion for aftermarket parts.
- Often tied to cash flow metrics like debt service coverage ratio (DSCR).
Equipment financing and leasing
Equipment financing can align payments with the productive life of specialized assets. Aerospace operators often finance CNC mills, autoclaves, five-axis machines, coordinate measuring machines, and avionics benches. Read the detailed equipment financing guide or explore Equipment Financing options.
- Potential benefits: preserve cash for materials and hiring while acquiring critical capacity.
- Structures: loans, leases, and sale-leasebacks; terms depend on credit, equipment type, and resale value.
- Example: finance a $450,000 five-axis mill over 5–7 years while backlog revenue ramps.
Business line of credit for working capital
Lines of credit provide flexible draw-and-repay access, useful for bridging payables and receivables during build cycles. Compare features in the business line of credit guide or explore a Business Line of Credit overview.
- Use cases: deposits to suppliers, progress payments, AOG events, seasonal inventory.
- Asset-based lines may be secured by receivables/inventory; unsecured lines are typically smaller with higher credit standards.
Invoice factoring and receivables financing
When receivables are strong but payment terms are long, factoring can accelerate cash flow by selling invoices at a discount. Aerospace firms serving primes or government agencies sometimes pair factoring with lines of credit. See the in-depth invoice factoring guide.
- Use cases: large, creditworthy customers; subcontracts with longer terms; bridging milestone invoices.
- Considerations: notification vs. non-notification, customer concentration, and compatibility with government contract assignment rules.
Short-term business loans
Short-term options can cover urgent needs, time-sensitive discounts, or quick-turn repairs. Learn the general features of a Short-Term Online Loan.
- Use cases: urgent tooling, rush materials to meet delivery windows, or an unexpected equipment repair.
- Considerations: higher effective costs; best when tied to a clear ROI or when bridging to a longer-term facility.
Some companies also review merchant cash advance products for fast access to capital; ensure you understand daily/weekly remittances and total cost.
Revenue-based financing for recurring revenue
For aerospace-adjacent software or services with recurring revenue, revenue-based financing can align repayments with monthly revenue. See Revenue-Based Financing to understand typical structures and considerations.
