Cash arrives after the work. That is the design problem.
A founder can acquire demand efficiently and still create a cash crisis when lead cost, delivery cost, invoice lag, and payment terms are treated as separate systems. This playbook connects them.
Pull the invoice trigger closer to the proof.
Select a node. The readout shows the decision that moves money through the system. The days below are an illustrative operating model, not a benchmark.
Stop funding the gap
Map the lead cost, delivery cost, contract trigger, and expected collection date before the sale is accepted.
cash_out → collection_dateFour controls. One cash path.
Terms before delivery
State due dates, accepted payment methods, deposits, and late-payment treatment in the contract and on the invoice.
Deposit for upfront cost
Use an advance or retainer when setup, discovery, reserved capacity, or materials create real cost before the main outcome.
Milestone = invoice trigger
Define deliverables and approval criteria that make the next invoice objective, visible, and hard to postpone.
Invoice at the event
Automate issuance at the agreed trigger and pair it with aging ownership, reminders, and a usable payment path.
A shorter term without a clear invoice, approval path, and collection owner is only a shorter sentence on paper.
Choose the lever that matches the work.
| Lever | Good fit | Failure mode |
|---|---|---|
| Deposit | Upfront cost or capacity reservation. | Ambiguous scope or unfair refund treatment. |
| Progress billing | Long project with measurable stages. | Milestones too vague to approve. |
| Early-pay discount | Fast cash is worth the margin tradeoff. | Discount erodes contribution or trains delay. |
| Net terms | Risk and relationship justify trade credit. | Seller finances an uncontrolled aging book. |
What should be measured?
Invoice lag, DSO, deposit coverage, aging by customer, approval delay, actual collection date, and the days between delivery and invoice.
Is negative CCC universal?
No. It depends on business model, terms, supplier relationships, customer behavior, and the timing of cash relative to operating costs.
Make cash timing a product decision.
Design the contract and billing path before increasing acquisition spend. Scale the offer that can finance its own delivery responsibly.
