You can win the lead, close the customer, and still run out of cash if the money leaves before the invoice is issued—and the invoice sits unpaid after the work begins. This playbook moves cash collection closer to the value event without turning the relationship into a negotiation trap.
Founders often optimize acquisition and close rate while accepting a silent financing burden: ad spend and delivery costs are paid today, but the customer pays in 30, 60, or 90 days—or after a vague “completion” milestone that keeps moving.
Shortening the cash conversion cycle is not demanding payment earlier at any cost. It is designing the contract, deposit, invoice trigger, and collection process so cash arrives near the work that creates value.
Select a checkpoint to see which commercial or operating decision changes the timing of cash. The exact days are illustrative; the sequence is the control system.
Map the lead cost, delivery cost, contract trigger, and expected collection date before the sale is accepted.
cash_out → collection_dateUse the shortest commercially reasonable path—not the most aggressive one. Each lever changes timing while preserving clarity and trust.
Choose due dates, payment methods, deposits, and late-payment rules during contracting. Terms shown only after delivery are not terms; they are a surprise.
Use an advance payment, setup fee, or retainer when discovery, onboarding, reserved capacity, or materials create cost before the main deliverable. State exactly what the payment covers.
Break long engagements into defined milestones with completion criteria, approval windows, and a pre-agreed invoice amount. A milestone that cannot be verified will not accelerate cash.
Issue the invoice at the contractual trigger, offer a usable payment method, monitor aging, and assign ownership for follow-up. Collection is a workflow, not a personality test.
Payment design should lower financing strain without creating avoidable disputes, margin leakage, or customer resistance.
| Lever | Use it when | Protect against |
|---|---|---|
| Deposit or retainer | Upfront work, reserved capacity, or material cost is real. | Calling a non-refundable fee “alignment” without clear scope. |
| Milestone billing | Work can be divided into measurable deliverables. | Vague completion criteria that delay approval and payment. |
| Early-pay discount | The cash value exceeds the margin and financing cost given up. | Offering a discount that trains buyers to delay or erodes contribution. |
| Net terms | The customer’s process and risk justify trade credit. | Treating Net 30 or Net 60 as free financing with no aging control. |
It is the time cash is tied up between paying for operating inputs and collecting cash from customers. A common formula is days inventory outstanding plus days sales outstanding minus days payable outstanding; service businesses may have little inventory, but receivables and payables timing still matter.
No. The deposit should reflect real upfront cost, reserved capacity, risk, and the customer’s buying context. An arbitrary deposit can create friction without improving the underlying economics.
Send it at the agreed contractual trigger: on order, upon receipt, at a defined milestone, or immediately after the service event. Waiting for an internal reminder adds avoidable days to DSO.
No. A Net 7 invoice can still be paid late if the customer’s approval process, invoice data, or payment method is broken. Terms must be paired with accurate invoices, accessible payment, and an aging workflow.
Track invoice date, contractual due date, actual collection date, DSO, deposit coverage of upfront cost, aging by customer, and the days between milestone completion and invoice issuance.
Design the cash path before you scale acquisition: clear terms, appropriate deposits, measurable milestones, immediate invoicing, and accountable collection.
