Construction companies routinely confront a financing decision: get a surety bond (a third-party guarantee that the project will be completed) or take an MCA (working capital to fund the project directly). These instruments serve different purposes but often get confused in early-stage contractor decision-making.
What a surety bond is.
A surety bond is a three-party agreement:
- Principal: the contractor doing the work.
- Obligee: the project owner (often a government agency).
- Surety: the bonding company that guarantees the work.
If the contractor fails, the surety pays the obligee and recovers from the contractor. The contractor pays the surety a premium of 1–5% of bond face value.
Types of construction bonds.
- Bid bond: guarantees the contractor will honor the bid if awarded. Required on most public projects.
- Performance bond: guarantees the work will be completed per contract.
- Payment bond: guarantees subcontractors and suppliers will be paid.
- Maintenance bond: guarantees workmanship for a period post-completion.
When MCAs make sense for construction.
- Bridging mobilization costs: project awarded but owner won't pay first draw for 60 days; MCA bridges the gap.
- Buying materials before draws: lumber, steel, concrete required upfront.
- Subcontractor payroll: weekly subs need to be paid before monthly draws arrive.
- Equipment rental deposits: cranes, lifts require large upfront deposits.
- Bonding company indemnification fees: some sureties require collateral that ties up cash.
- Small projects under $100K: bonds may not be required; MCA fills working-capital need.
When MCAs DON'T make sense for construction.
- As a substitute for a bid bond: project owners require bonds, not cash; MCA doesn't satisfy the requirement.
- Long projects (6+ months): MCA daily debits eat working capital before final draws arrive.
- Public works: most require bonds; MCA can complement but cannot replace.
- Projects with strict draw schedules: MCA daily debits create cash-flow misalignment.
Decision framework.
| Scenario | Use bond | Use MCA |
|---|---|---|
| Public project requiring performance bond | Yes | No |
| Private project, owner not bonding | Maybe | Yes |
| Need working capital between draws | No | Yes |
| Subcontractor payroll | No | Yes |
| Material purchase before mobilization | No | Yes |
| Building bonding capacity (long-term) | Yes | No |
Cost comparison.
- Performance bond on $500K project: 1.5% premium = $7,500 (one-time, often refunded partially).
- MCA $100K for 9 months at 1.32 factor: $32K cost.
The bond is cheaper but serves a different purpose. They're complementary, not substitutes.
Bond capacity and MCA interaction.
Bonding companies underwrite contractors based on:
- Net worth: typically need 10% of single-project size in working capital.
- Liquidity: cash + receivables.
- Backlog: current uncompleted work.
- Indemnification: personal guarantees from owners.
An MCA appears as debt on bank statements, which:
- Reduces effective working capital (daily debits = cash outflow).
- Reduces bond capacity (less liquidity = smaller bonds available).
- Can trigger surety covenant violations (some require pre-approval of new debt).
Worst-case scenario.
Contractor takes $100K MCA for working capital, simultaneously applies for $1M bond capacity increase. Surety pulls bank statements, sees daily MCA debits, declines capacity increase, contractor loses the project they were planning to bid.
Sequence matters.
Best practice:
- Set bonding capacity first before any MCA.
- Use MCA tactically for projects below bonding capacity.
- Communicate with surety before taking MCA on a bonded job.
- Pay down MCA before requesting capacity increases.
Construction-specialty MCA funders.
- CAN Capital: construction-friendly underwriting.
- Credibly: accepts contractor licenses and project documentation.
- PIRS Capital: specialty in trades.
- Generic funders: skeptical of construction due to project lumpiness; pricing 0.05–0.10 higher.
AIA billing and MCA.
Commercial contractors using AIA (American Institute of Architects) billing have predictable draw schedules. MCA funders familiar with AIA documents underwrite better than those reading raw bank statements.
Common pitfalls.
- Taking MCA without surety approval: triggers covenant violation, bond cancellation.
- MCA timing mismatched to draw cycle: 30-day draws + daily MCA = cash crunch mid-month.
- Mixing personal and business funds: surety and MCA both flag.
- Over-leveraging on one project: MCA debits a project's profit margin before final payment.
- Not disclosing MCA on bond renewal: insurance fraud risk.
Takeaway. Surety bonds and MCAs serve different purposes — bonds guarantee project completion (required for most public work, recommended for large private projects), MCAs provide working capital between draws or for non-bonded small projects; the financing decision should sequence bonding capacity first, then use MCAs tactically with surety approval to avoid covenant violations that can collapse bond capacity entirely.
Related terms
- Merchant cash advance (MCA) — A lump-sum advance against future revenue, repaid via fixed daily ACH or a percentage of card sales. Legally a sale of future receivables, not a loan.
- MCA vs loan (legal distinction) — An MCA is legally a purchase of future receivables, not a loan. This distinction exempts MCAs from state usury caps but requires specific contract structure — including reconciliation provisions.
- Personal guarantee (PG) — A clause making the business owner personally liable if the MCA defaults. Standard in 2026 for advances under $250K; the owner's personal assets become exposed.
