Build the monthly cash budget from actual collection and payment timing, not annual EBITDA divided by twelve. Separate acquisition funding from operating cash, reconcile earned revenue to receipts, schedule payroll, supplies, rent, debt, capital spending, and adviser-modeled taxes, then test the lowest cash point under supported downside assumptions.
What question does the monthly budget answer?
The budget asks whether the buyer can meet obligations when they are due during the acquisition and operating transition. Annual EBITDA can be positive while the bank account falls below the amount needed for payroll, rent, service obligations, or debt payments.
Begin with the expected closing date and a defined opening cash balance. Specify whether the balance is inside the acquired business, separately funded by the buyer, restricted, or already committed to another use. A purchase-price payment or seller escrow is not automatically available operating cash.
The SBA business-management resources include financial management as an ongoing responsibility. They do not prescribe a standard med spa cash reserve. The buyer needs a business-specific forecast built from records, contracts, actual terms, and qualified financial advice.
How does this differ from acquisition sources and uses?
Sources and uses show how the buyer funds price, fees, equipment, working capital, and other transaction needs. The monthly cash budget shows what happens to operating liquidity after those uses occur. The two models should reconcile, but they answer different questions.
If $100,000 is included as opening working capital in acquisition uses, do not also assume an unrelated $100,000 cash injection into the operating forecast without explaining the same source. Conversely, working capital can include noncash assets and liabilities rather than a bank balance, so a purchase agreement target may not provide cash for payroll.
Identify restricted reserves, escrow, undrawn facilities, unpaid equity commitments, and lender conditions separately. A potential source is not available cash until the relevant requirements and timing are supported. Do not hide a forecast shortfall with an uncommitted “additional financing” line.
Which monthly inputs are needed?
| Input | Evidence | Timing question |
|---|---|---|
| Opening cash | Funding and closing reconciliation | What is available on day one? |
| Collections | POS, processor, bank, customer ledgers | When does money arrive? |
| People costs | Payroll calendar and supported staffing plan | Which pay dates occur? |
| Supplies and vendors | Orders, terms, inventory, contracts | When must suppliers be paid? |
| Occupancy and debt | Lease and actual loan schedules | What fixed payments are due? |
| Capital and transition | Quotes and implementation calendar | When is one-time cash required? |
| Taxes and reserves | Qualified adviser inputs | Which amounts and dates apply? |
The IRS recordkeeping guidance identifies supporting documents that help establish income and expenses. The forecast should preserve its source references and assumptions so another reviewer can distinguish verified timing from estimates.
How do earned revenue and collections reconcile?
Map service revenue, customer deposits, packages, memberships, receivables, refunds, taxes, tips, fees, and processor timing. A customer can pay before a service is earned or receive a service using earlier collections. The forecast should show receipts while the earnings model measures the appropriate revenue basis.
The IRS Publication 538 explains tax accounting methods, not the acquisition’s complete operating forecast. An accountant should reconcile reporting bases and determine actual treatment. Do not use a cash-method label to ignore future service commitments or an accrual label to assume receivables convert immediately.
Forecast by meaningful cohorts where available: ordinary visits, membership collections, prepaid redemptions, retail, and financing-provider settlements. Use the actual processor schedule and observed payment behavior. A single monthly collection percentage may be too crude when a large promotion or system change crosses the closing date.
What does an illustrative first month look like?
Assume a fictional opening cash balance of $90,000 and $180,000 operating collections. Payments are $72,000 payroll, $34,000 supplies, $14,000 rent, $25,000 other operating costs, $18,000 debt service, and $30,000 capital spending. Total payments are $193,000.
Closing cash is $90,000 + $180,000 − $193,000 = $77,000. This simplified teaching case excludes taxes and other items solely to isolate the arithmetic; a real budget must include adviser-modeled obligations and all actual uses. These are invented amounts, not med spa cost ratios or financing terms.
The month can show a cash decline even if recurring operations are profitable because capital spending and payment timing matter. Do not subtract the $30,000 equipment payment from cash and then subtract depreciation as another cash outflow. Keep the earnings-to-cash bridge explicit.
How does the lowest cash point change the decision?
Continue the fictional case with $77,000 opening cash in month two, $140,000 collections, and $187,000 total payments. Closing cash falls to $30,000. If the buyer’s stated planning minimum is $60,000, the modeled shortfall is $30,000.
The $60,000 minimum is an arbitrary example assumption, not a recommended reserve for every practice. The actual minimum should reflect payroll, fixed obligations, volatility, vendor terms, access to committed liquidity, and the buyer’s risk capacity. A positive balance is not automatically sufficient.
Monthly ending balances can also hide an intra-month problem. A large payroll may be due before a delayed payout arrives. Use a weekly or daily bridge around critical dates when needed. The purpose is to identify the true funding point rather than produce a reassuring month-end average.
What downside scenarios deserve their own columns?
Test slower collections, lower visits, reduced provider availability, delayed hiring, device downtime, refunds, higher supplies, rent changes, and delayed financing where relevant. Tie each scenario to a specific assumption and explain whether costs decline with revenue or remain fixed.
Do not combine every imaginable worst event into an unlabeled case or assume no adverse event can occur together. Use supported operating scenarios and a separate severe stress if helpful. The buyer should understand what triggers additional action and how much time remains before cash becomes insufficient.
Keep upside separate. A new service, higher price, marketing improvement, or staffing expansion may require spending before it generates collections. Do not use unverified growth to cover a current funding gap while leaving the corresponding implementation cost out of the model.
How should actual results update the forecast?
- Reconcile opening cash to bank and processor records.
- Compare actual receipts and payments with the budget.
- Explain volume, price, timing, staffing, and one-time differences.
- Update remaining obligations and committed funding.
- Recalculate the lowest cash point and minimum-buffer gap.
- Assign actions, owners, and decision dates.
Preserve prior versions rather than overwrite the assumptions without explanation. A forecast that always matches the latest result loses its value as a decision record. The buyer needs to know whether a variance is a temporary timing movement or a persistent change in operating economics.
The lender’s projection and the buyer’s cash budget should use consistent facts, while recognizing that formal underwriting calculations can differ. Obtain actual lender terms and current requirements rather than infer payment capacity from a simple spreadsheet balance.
What actions can address a shortfall?
Possible responses include additional verified equity, revised timing, supported vendor terms, reduced discretionary spending, changed price or structure, delayed closing, or stopping. None should be assumed available. Essential clinical, safety, legal, and customer obligations cannot be treated as optional simply to improve the forecast.
Use the valuation hub, buyer roadmap, operations guidance, and seller hub. The diligence guide, membership obligation guide, and Four-Number Med Spa Valuation Screen connect cash timing with verified earnings.
The final budget should expose the buyer’s decision, not conceal it. If the business requires more liquidity than the buyer can reliably provide, an attractive annual EBITDA figure does not resolve the gap.
What else do owners and buyers ask?
Can annual EBITDA divided by twelve serve as a cash budget?
No. It misses collection and payment timing, seasonality, debt principal, capital spending, taxes, working capital, and transition costs. Build monthly receipts and payments from actual evidence, reconcile opening cash, and examine critical intra-month dates. Annual profitability can coexist with a cash shortfall when obligations fall due before collections arrive.
Is the purchase agreement’s working-capital target the same as opening cash?
Not necessarily. The target may include receivables, inventory, prepaids, payables, or other defined items while excluding cash and debt. Read the actual agreement and reconcile it to the buyer’s funding plan. A delivered working-capital balance does not automatically provide a bank deposit large enough to meet immediate payroll and rent.
How much minimum cash should a buyer keep?
There is no universal amount established by this guide. Set a documented planning minimum using actual payroll, fixed obligations, volatility, service commitments, vendor terms, committed liquidity, and risk capacity. Test timing and downside, and obtain qualified advice. The fictional $60,000 threshold is an arithmetic assumption rather than a recommended reserve.
Can an uncommitted loan be used to fill the budget gap?
Do not treat it as available cash. Identify the lender, terms, conditions, timing, eligibility, and actual commitment before relying on funding. A model should show unresolved financing separately. If the buyer cannot support the shortfall with verified resources, revise the plan, timing, terms, or acquisition decision rather than insert an unsupported balancing source.
