Retainage Squeeze on a Growing Backlog
Ridgeline Construction LLC holds a Tennessee BC license with a $1.5M monetary limit and carries a $2M aggregate / $1M single-project bonding line. Backlog is $2.4M across four jobs that cover overhead but throw off no surplus cash. Cash on hand is $38,000; the $250,000 line of credit is drawn to $60,000 at 9.5%. Company-wide payroll runs $46,000 per week. Ridgeline is offered a 20-week, $620,000 tenant-improvement package at an 8% gross margin, with 10% retainage, monthly billing, a 21-day owner invoice-approval cycle, and payment 45 days after approval. Job costs run at 92% of billings. The owner wants mobilization in three weeks and has already sent a letter of intent. The bank covenants a 1.20 current ratio.

Assumptions and arithmetic
- Billings: $620,000 ÷ 20 weeks ≈ $31,000/week ($124,000 per 4-week billing cycle).
- Job cost outflow: 92% × billings ≈ $28,500/week.
- Cash conversion: bill at the end of each 4-week cycle + 21 days to approve + 45 days to pay = cash lands roughly 66 days after billing (about 9½ weeks after the work was performed).
- Retainage: 10% withheld from every dollar received.
| Week | Cumulative job cost out | Cash received (90% of billed) | Net position |
|---|---|---|---|
| 4 | $114,000 | $0 | –$114,000 |
| 9 | $256,500 | $0 | –$256,500 |
| 13 | $370,500 | $111,600 (cycle 1) | –$258,900 |
| 17 | $484,500 | $223,200 (cycles 1–2) | –$261,300 |
| 20 | $570,000 | $223,200 | –$346,800 |
Conclusion: peak funding need is roughly $260,000 during construction, growing to about $347,000 at completion once the final two invoices (and the $62,000 retainage) are outstanding.
Available liquidity: $38,000 cash + ($250,000 – $60,000 undrawn) = $228,000. That is short before the job is half complete, and the shortfall widens every week after that. Ridgeline cannot fund this job as written. Note also that interest on a $200,000+ average draw at 9.5% eats about $19,000 of the $49,600 gross margin, cutting the return roughly in half even if the bank cooperates.
2. What specific commercial terms would you renegotiate before signing, and which financial indicators should the owner watch weekly if the job is taken?

Renegotiate, in priority order:
- Retainage to 5% or a retainage bond. Retainage is not a margin problem, it is a liquidity problem - it is the last money in and the slowest.
- Billing frequency to bi-weekly or milestone draws. Cutting the cycle in half pulls roughly $60,000 of cash forward by 4–6 weeks, which is worth more than a point of margin.
- Kill the 21-day approval lag or add an automatic-approval clause ("deemed approved if not rejected in 10 days"). Undisputed-amount statutes and prompt-pay principles support this.
- Mobilization payment of 10% and a stored-materials provision for the millwork/mechanical packages.
- Escalation or a purchasing contingency on any material line not bought out at contract execution.
Weekly dashboard:
- Cash flow projection vs. actual receipts, by job, 8 weeks forward
- Days sales outstanding (DSO) by owner - a 66-day cycle is already the constraint
- Under/over billings (a large underbilling balance means costs are running ahead of billings)
- Current ratio against the 1.20 covenant and line-of-credit headroom
- Job cost-to-complete vs. original estimate, by division
A profitable income statement with a negative operating cash flow is the classic construction failure pattern; the schedule of values and the billing cycle, not the markup, are what decide solvency.
3. Separately, what happens to the surety and monetary-limit picture if Ridgeline signs this contract?
Read the worked answer
Bonding: aggregate backlog would move to $2.4M + $0.62M = $3.02M against a $2.0M aggregate program - a 50% overrun. The single-project limit ($1.0M) is satisfied, but the aggregate is not. Writing this bond without surety consent breaches the indemnity/general agreement and risks the surety refusing bonds on the next job, which is worse than losing this one. Options: get written surety consent for an increased aggregate, obtain a bond-only rider, or negotiate with the owner to waive the performance bond in exchange for a larger retainage or a letter of credit - a trade that makes the cash problem worse, which is the point to raise with the owner.
Monetary limit: the license limit ($1.5M) applies per project, not to aggregate backlog, so a $620,000 contract is inside the limit. Do not confuse the two - but do verify the license limit on the Board's records rather than on the certificate in the truck, since limits change with financial statements.
Decision: a job that cannot be bonded as bid and cannot be cash-funded as drafted is not a job; it is a financing transaction the company is not equipped to make.
