Profit is a theory—cash is reality. The right bookkeeping system doesn’t just keep you compliant; it compresses your cash conversion cycle, prevents surprises, and fuels growth. In this playbook, we turn books into a cash engine using forecasting, AR/AP levers, inventory discipline, and tax-aware timing. Prefer to hand it off? Our team can run monthly books, 13-week forecasts, and quarterly tax plans. Explore our Bookkeeping, Outsourced Controller/CFO, and Tax Preparation.
The Cash Flow Framework
- 13-Week Cash Forecast: a rolling weekly view of inflows/outflows, reconciled to bank balances.
- Cash Conversion Cycle (CCC): reduce days sales outstanding (DSO), optimize inventory days (DIO), and extend days payables outstanding (DPO) responsibly.
- Margin Discipline: price for gross margin first; track contribution margins by SKU/service/job.
- Working Capital Policy: deposits, retainers, credit limits, and payment terms—documented and enforced.
AR Levers that Pull Cash Forward
- Invoice same-day; require deposits/retainers for projects; milestone billing for long jobs.
- Offer ACH with autopay; card on file for subscriptions/recurring services.
- Collections cadence: 3-7-14-21 day reminders; statements weekly on past-due; friendly + firm scripts.
- Early-pay incentives and late-fee policies where legal; credit checks and limits for new accounts.
AP Levers that Protect Runway
- Consolidate vendor cycles to 2–3 payment days/month; avoid “anytime” ad-hoc disbursements.
- Negotiate Net 30–45 with key vendors; use virtual cards for control & rewards.
- Prioritize by impact: payroll & taxes → mission-critical vendors → everything else.
- Use approval workflows for spend thresholds; enforce PO or pre-approval for CapEx.
Inventory & COGS (If Applicable)
- Adopt demand-based reordering (ROP/EOQ); kill dead SKUs; tighten vendor MOQs.
- Monthly shrink & adjustments; land freight & duties into COGS correctly.
- Cycle counts beat annual surprises; chase gross margin by SKU, not just blended margin.
Payroll & Cadence
- Align payroll dates with cash inflows; avoid off-cycle payrolls unless critical.
- For S-Corps, document reasonable comp and use accountable plans to reimburse expenses.
- Track labor by job/class for true job costing and pricing decisions.
Forecasting & Dashboards
- Weekly 13-week forecast (receipts, disbursements, taxes); variance review every Monday.
- KPIs: gross margin %, operating margin %, DSO/DIO/DPO, cash burn/runway, debt service coverage (DSCR).
- Scenario planning: base, stretch, and downside with hiring and inventory impacts.
Tax-Aware Cash Timing
- Quarterly estimates on safe-harbor; avoid surprise year-end balances.
- Time CapEx, bonus depreciation, and prepayments deliberately—don’t just “buy deductions.”
- S-Corp vs. sole prop modeling; retirement contributions coordinated with cash constraints.
What We Do (Month–Quarter–Year)
Monthly
- Reconcile bank, credit, payment processors; lock the month with P&L, Balance Sheet, and Cash Flow.
- AR/AP aging reviews with action lists; update 13-week forecast; vendor & pricing audits.
- Inventory roll-forward; job/segment margin analysis; owner distributions tracking.
Quarterly
- Estimated tax calculations; working capital review; KPI dashboard & pricing tune-ups.
- Debt schedule updates; covenant checks; cash runway plan.
Annually
- Tax returns (1120S/1065/1120; 1040 with Schedules C/E), 1099 e-filing, and year-end planning.
- Budget build; cost structure reset; insurance & vendor re-quotes.
Common (Costly) Mistakes
- Confusing profit with cash; no 13-week forecast or aging discipline.
- Letting DSO creep; paying vendors early without discounts; missing AP batching.
- Bloated SKUs and stale inventory; miscoded COGS; unreviewed merchant fees.
- Skipping quarterly estimates; “December deduction shopping” that drains cash.

FAQs
How do I build a reliable 13-week cash forecast?
Start from reconciled bank balances; map recurring inflows/outflows; add weekly AR collections assumptions and AP batches; reconcile forecast vs. actual every week and adjust.
What’s a good target DSO/DPO?
It’s industry-specific, but the direction is universal: lower DSO via faster invoicing/autopay and healthy DPO via negotiated terms—without harming vendor relationships.
Can I grow and keep cash positive?
Yes—pair growth with contribution margin checks, deposits/milestones, disciplined inventory buys, and a weekly forecast to prevent overextension.
How often should I revisit pricing?
Quarterly for inputs-sensitive businesses; at least semiannually for services. Always tie pricing to target margins and current costs.
