Working capital is the cash trapped between paying suppliers, holding inventory, and collecting receivables. Automation reduces idle days—not by “motivating sales harder,” but by removing manual delays in invoicing, approvals, and collections.

Cash conversion cycle (CCC) in plain numbers

Common definitions (verify against your financial statements):

  • DSO (days sales outstanding): how fast customers pay.
  • DIO (days inventory outstanding): how long cash sits on shelves.
  • DPO (days payables outstanding): how long you wait to pay vendors.

CCC ≈ DSO + DIO − DPO (lower is better). If DSO is 48, DIO 35, DPO 32 → CCC ≈ 51 days of financed working capital you must fund via equity, revolver, or supplier terms.

Automation levers that actually move cash

  1. Invoicing same-day with correct PO references—delays here silently extend DSO.
  2. Collections cadence—automated reminders at T+7/T+14, escalation rules, not ad-hoc emails.
  3. AP approval workflows with mobile approval to avoid “stuck in inbox” DPO noise (don’t pay early by accident).
  4. Inventory signals tying purchasing to sell-through, not monthly bulk buys.

Cost of bridging CCC

If a line of credit carries 11% APR, shaving 10 CCC days on $400k monthly throughput is material interest saved—model short-term rates with the interest calculator before dismissing “process work” as non-financial.

Controls (non-negotiable)

Segregate duties on vendor creation, wire approvals, and refund issuance. Faster systems with weak controls are how fraud scales.
