A profitable project can still need cash before the next milestone
A 24,000 project earns 6,000 gross profit yet reaches a 2,400 funding gap. Follow the deposit, delivery costs and collections in order.
The short answer
Profit compares total revenue with total cost. Funding need depends on when costs are paid and revenue is collected. A positive profit at the end of a job does not ensure a nonnegative cash balance while the work is underway.
Follow an illustrative three-phase project
A project sells for 24,000 and costs 18,000, so final gross profit is 6,000. The client pays 25% before work, 25% after phase 1, 25% after phase 2 and the final 25% after phase 3. Costs are paid 40%, 40% and 20% across the three phases. Assume zero starting cash and that each phase's costs are paid before the next collection.
| Event | Change in cash | Balance |
|---|---|---|
| Deposit collected | +6,000 | 6,000 |
| Phase 1 costs paid | −7,200 | −1,200 |
| Phase 1 payment collected | +6,000 | 4,800 |
| Phase 2 costs paid | −7,200 | −2,400 |
| Phase 2 payment collected | +6,000 | 3,600 |
| Phase 3 costs paid | −3,600 | 0 |
| Final payment collected | +6,000 | 6,000 |
The lowest balance is −2,400. The project therefore needs 2,400 of additional funding under this sequence. The final 6,000 profit does not fund a cost that arrived before the corresponding collection.
Change the sequence, not the profit
Try a 40% deposit, 20% after phase 1, 20% after phase 2 and a 20% final payment, with the same costs. Collections are 9,600, 4,800, 4,800 and 4,800. The balance after each phase's costs is 2,400, zero and 1,200 respectively. No additional funding is needed in that simplified sequence; the final profit remains 6,000.
This is a scenario comparison, not a claim that a client will agree to the deposit. Use the cash-flow calculator to preserve a baseline and test the proposed milestones.
An invoice is not a collection
The calculation assumes funds arrive at the stated boundary. Issuing a milestone invoice does not establish that cash is available to pay the next cost. A late collection can deepen the trough, and expenses inside a phase may occur before a phase-end summary suggests. For a real funding plan, record expected collection timing and review the job alongside other commitments.
Keep funding assumptions with the proposal
The proposal checklist includes the deposit, milestones and client dependencies. The break-even tool asks a separate question about cost over uncertain duration. Neither tool calculates financing charges, tax, default risk or the legal effect of payment terms. Use the examples to expose the assumptions before committing to the job.
