A business diagnostic checklist is a fast health snapshot across finance, operations, strategy, and people that tells you where your company is bleeding value right now. The move is simple: run it today, score each item, and convert your worst finding, usually cash, into a 90-day fix with a named owner. Templates and advisor guidance follow below.
TL;DR:
- Cash runway is critical, and a red score indicates less than three months of operation remaining at current expenses.
- Prioritize fixing cash flow and margin issues within the first 7 to 30 days, attaching specific owners and deadlines.
- Engage an advisor if cash projections are critically short or if persistent margin erosion occurs despite internal attempts.
- Conduct the checklist monthly to catch slow-building issues like customer concentration or inventory turnover before they escalate.
- Focus on fixing the most urgent problems first, such as cash and accounts receivable, rather than less immediate strategic concerns.

1. Ten checkpoints that reveal your business’s real condition
A real diagnostic does not wander into every corner of the business. It hits the ten places where problems actually start, and it forces you to write down evidence instead of relying on a gut feeling.
- Cash runway. How many months can you operate at current burn without new revenue or financing?
- Rolling forecast accuracy. Does your forecast get updated weekly, and how far off was last month’s number?
- Gross margin by product line. Which SKUs are actually profitable once you account for shipping and returns?
- AR/AP aging. Are customers paying late, and are you paying suppliers on time?
- Bank reconciliation cadence. Is someone reconciling accounts monthly, or has it slipped to “whenever”?
- Customer concentration. Does one customer or channel account for an outsized share of revenue?
- Repeat purchase rate. Are you retaining customers, or replacing them every quarter through paid acquisition?
- Inventory turnover and fulfillment timing. How long does stock sit before it sells, and are orders shipping on schedule?
- Supplier concentration and cost leakage. What happens if your primary supplier raises prices or misses a shipment?
- Value proposition and pricing alignment. Can you state, in one sentence, why a customer picks you over the alternative, and does your pricing reflect that?
Beyond the numbered items, watch for softer signals that often surface at the same time:
- Returns creeping up without a clear product or fulfillment cause.
- No one person owns a given KPI, so problems get discovered late.
- Sales-tax nexus questions that nobody has revisited since the business grew into new states.
- A dashboard that shows last month’s numbers instead of this week’s.
The SBA’s guidance on everyday planning frames this well: forecast your key numbers, review them against expectations and prior periods, and decide what to stop, start, or change. That habit, repeated monthly, is most of what a diagnostic checklist formalizes.
For each checkpoint, capture the evidence, not just a score. Our guide to measuring financial health walks through building that kind of evidence trail for the finance items specifically.
Pro Tip: Run the checklist on a Friday afternoon, when the week’s numbers are fresh and you are not mid-crisis on any one item.
2. Scoring the checklist and building your 90-day plan
A diagnostic without a scoring method just becomes a list you feel bad about. Keep it simple: score each of the ten checkpoints 0 (red, urgent), 1 (amber, watch), or 2 (green, healthy).
- Count your reds first. Any red on cash runway, gross margin, or customer concentration jumps to the front of the line regardless of what else is flagged.
- Sort ambers by dependency. A margin problem tied to a supplier issue should be fixed before you address something downstream of it.
- Assign a 7-day action to anything that is actively losing money right now, typically cash and AR.
- Assign a 30-day action to structural fixes: renegotiating supplier terms, correcting pricing, tightening reconciliation cadence.
- Assign a 90-day action to anything strategic: repositioning, channel diversification, or a pricing overhaul.
Say your cash-runway score comes back red at three months. The 7-day step is a 13-week rolling cash-flow view so you can see the shape of the problem, not just the balance. The 30-day step is renegotiating payment terms with your two slowest-paying customers and your largest supplier. The 90-day step is a pricing or SKU-mix change that improves margin enough to extend runway on its own. Each step needs a name attached to it and a date you will check whether it actually happened.
Pro Tip: Write the owner and deadline directly next to each checklist item. A fix with no name attached rarely gets done by the next review.
3. Deciding when to bring in an advisor and what to ask them
Some findings you can fix yourself over a weekend. Others need outside expertise, particularly when the problem touches tax exposure, complex financing, or a pattern of failed attempts to fix the same margin leak.
Bring in an advisor when you see:
- Cash runway that appears critically short with no clear path to extend it internally.
- Margin erosion that persists after you have already tried an obvious fix.
- Sales-tax nexus or multi-state compliance questions you cannot answer confidently.
- A strategic decision, like raising capital or restructuring, where the stakes are too high to guess.
Forbes Advisor’s guidance on choosing a financial advisor recommends interviewing 2 to 4 candidates before committing, and evaluating fiduciary status, fee structure, and whether they typically work with businesses like yours. Ask directly whether they will coordinate with your existing CPA or attorney rather than working in isolation. Map your questions to your checklist results: if margins are your red flag, ask how they approach margin diagnostics specifically, not just general financial planning. Our guide to how advisors fit into founder decisions goes deeper on matching advisory scope, whether a one-off diagnostic or a retained relationship, to the size of the problem you found.
4. How a founder-to-founder diagnostic actually runs
The gap between knowing your numbers are wrong and knowing exactly which number to fix first is where most diagnostics fail founders.
Quick wins tend to show up in cash visibility and pricing within the first few weeks. The deeper fixes, the ones tied to positioning or channel mix, take longer and need sustained attention rather than a single engagement.
What most business owners get wrong about diagnostics
Most owners treat a business diagnostic as a once-a-year event, something you do before a big decision or when a lender asks for it. That is backward. The checklist above is most useful as a monthly habit, because problems like margin erosion and customer concentration build slowly and are far cheaper to fix in month two than month eight.
The other mistake is treating every red flag as equally urgent. It is not. Cash runway problems compound daily. Strategic positioning problems compound over quarters. Owners who spend their first available hour on a branding question while runway sits at four months have their priorities backward, and no amount of polish fixes a business that runs out of cash first.
If you take one thing from this checklist, take the discipline of scoring before you act. The instinct to fix the loudest problem, rather than the most urgent one, is what keeps otherwise capable founders stuck rehearsing the same fire drill every quarter.
Get a rapid expert read on your numbers
If running the checklist surfaces more red flags than you have time to fix alone, the DTC Operator Diagnostic turns the same checkpoints into a prioritized, founder-specific action plan, typically centered on cash clarity and a concrete 90-day sequence. If you just need a fast second opinion on one finding, a Founder Hour gets you an hour of direct advisory time to pressure-test the decision before you commit resources to it.
Start with whichever matches the size of the problem you found: book the diagnostic for a full picture, or the Founder Hour for a single sharp question.

FAQ
What is a business diagnostic?
A business diagnostic is a structured review of a company’s finances, operations, strategy, and people, designed to identify what is constraining growth or profitability. It typically scores specific checkpoints, like cash runway or gross margin, rather than offering a general impression of business health.
What are the 7 basic elements of a business plan?
Definitions vary slightly by source, but a common version includes an executive summary, company description, market analysis, organization and management structure, product or service line, marketing and sales strategy, and financial projections. These elements overlap closely with the finance, strategy, and people checkpoints in a diagnostic checklist.
How do I start an LLC checklist?
Forming an LLC generally involves choosing a business name, filing formation documents with your state, obtaining an EIN, and setting up separate business banking and bookkeeping. The SBA’s business guide covers the financial setup steps once the entity is formed.
What are the essential parts of a business plan?
Beyond the core seven elements, many plans add sections covering funding requests, appendices with supporting documents, and detailed financial statements like cash-flow forecasts. The exact count varies by template, so match the sections to what your specific audience, whether a lender or investor, actually needs to see.
How much does a business diagnostic cost?
Commerce Catalyst’s DTC Operator Diagnostic is a $197 one-time engagement, while a single Founder Hour advisory session runs $500 per hour for founders who want a faster, narrower conversation.
