The core difference
Profit measures performance (revenue − expenses) within a period. Cash flow tracks money in and out, regardless of when revenue is earned.
- Invoice today, get paid in 30 days → profit now, cash later.
- Buy inventory now, sell next month → cash out now, profit later.
Simple reconciliation checklist
- Accounts receivable aging (0–30, 31–60, 61–90+)
- Accounts payable schedule (who you owe & when)
- Inventory turns (COGS / avg. inventory)
- Deferred revenue (prepayments you still owe work for)
Operational fixes
- Shorten payment terms; add % for Net‑30
- Deposit or milestone billing for projects
- Lean inventory (ABC analysis, reorder points)
- Negotiate supplier terms to mirror your cash in
Direct method cash map
| Stream | In/Out | When |
|---|---|---|
| Customer receipts | In | On payment date |
| Supplier payments | Out | On your pay date |
| Payroll & tax | Out | Per cycle |
| Capex | Out | On purchase |
Move: Build a 13‑week cash forecast; update weekly.
Decision checklist
- Will this improve contribution margin in 60 days?
- What is the effect on cash in 30/60/90 days?
- What can be delayed or made variable?
Map timing differences
Create separate lines for invoicing, cash receipts, payables, payroll, and capex. Profit can be up while cash is down if receipts lag.
13‑week forecast
- Weekly buckets for cash in/out.
- Mark certainties vs assumptions.
- Reconcile to bank balance every Friday.
Operational fixes
- Deposits/milestones, earlier billing.
- Inventory turns and reorder points.
- Mirror supplier terms to customer terms.
13‑week forecast skeleton
- Rows: cash in (receipts), cash out (payroll, COGS, overhead), net.
- Columns: week 1–13; flag certainty vs assumption.
- Reconcile every Friday to bank balance.
Fast cash wins
- Milestone billing & deposits on new projects.
- Invoice same‑day; auto reminders at 3/7/14 days.
- Turn slow inventory with bundles or outlet listings.
Receivables playbook
- Deposit or milestone billing on kickoff.
- Invoice same‑day; auto‑chase at 3/7/14 days.
- Offer ACH with small discount to cut card fees and speed cash.
Inventory levers
- ABC analysis; buy A’s just‑in‑time, bulk B’s with breaks, trim C’s.
- Raise turns with bundles and season‑end clearance.
- Use reorder points tied to lead time variability.
Working capital levers
- Shorten DSO: deposits, milestones, automated reminders.
- Extend DPO: negotiate Net‑30/45 where feasible.
- Reduce inventory days: smaller, more frequent buys in volatile demand.
Cash early‑warning indicators
- Receivables > 1.2× monthly revenue.
- Inventory grows while sell‑through falls.
- Breakeven revenue creeping up for 3 months.
FAQ: Cash vs profit
Q: Why is profit up but cash down?
A: Receivables growth, inventory build, or capex can absorb cash even when P&L looks healthy.
Q: What’s a good runway?
A: Aim for 8–12 weeks of operating outflows available.
Example weekly cash cadence
- Mon: invoice & follow‑ups
- Wed: payables planning & vendor calls
- Fri: reconcile bank & update 13‑week forecast
Cash conversion cycle (CCC) primer
CCC = DIO + DSO − DPO. Lower is better. Improve by faster collections (lower DSO), leaner inventory (lower DIO), and extended payables (higher DPO).
Red‑flag patterns
- Revenue up but CCC worsening month over month.
- Payables stretched beyond agreed terms.
- Rising returns or warranty claims hitting cash.
Case: collections discipline
Switching from manual invoices to auto‑billing with ACH cut DSO from 39 to 21 days, freeing one payroll cycle of cash.
Cash glossary (fast)
- DSO: Days Sales Outstanding—lower is faster cash.
- DIO: Days Inventory Outstanding—stock tied up.
- DPO: Days Payables Outstanding—time to pay vendors.
Collections SOP
- Deposit on contract; invoice milestones with dates.
- Automate reminders; escalate to phone at day 10.
- Offer ACH or card on file; small fee for late payment.
Cash buffer targets
Reserve 1–2 months of fixed costs; add 0.5 months for seasonal businesses. Refill buffer before increasing owner pay.
Cash ladder for tough months
- Accelerate receipts (deposits, milestone billing).
- Defer non‑critical capex.
- Negotiate terms on overhead vendors first.
- Reduce inventory buys to historical sell‑through.
Collections scripts
Day 3: “Friendly reminder—invoice #123 is due on [date]. Need a fresh link?”
Day 10: “Can we schedule payment today? ACH link attached.”
