What is a 13-week cash flow forecast, and how do practitioners build one?
A 13-week cash flow forecast is a rolling, week-by-week projection of a company's cash receipts and disbursements over the next quarter, updated every week and compared with actual results. Turnaround advisors, lenders and boards use it to see when liquidity gets tight and which payments the business can safely make.
What a 13-week cash flow forecast is
A 13-week cash flow forecast is a rolling, week-by-week projection of the cash a business expects to collect and pay out over the next quarter, built from actual receipts and disbursements rather than accounting profit. Each week the oldest week drops off, a new week 13 is added, and last week's forecast is compared line by line with what actually cleared the bank.
Thirteen weeks is long enough to capture a full cycle of payroll runs, monthly rent, quarterly tax payments and most debt service dates, and short enough to forecast receipts customer by customer and payments vendor by vendor. That granularity is why turnaround advisors, chief restructuring officers, lenders and boards lean on it when liquidity is tight.
How a 13-week model is built
Most practitioners build it in the same order:
- Start from available bank balances by account, reconciled to statements, not the book balance in the general ledger.
- Forecast receipts from the accounts receivable aging and each customer's actual payment history, keeping collections of existing invoices separate from cash from new sales.
- Place disbursements in the week they will leave the account: payroll and benefits on real pay dates, rent, critical vendors, taxes, insurance, interest and principal.
- Add non-operating lines such as professional fees, restructuring costs and capital expenditure.
- Calculate ending cash and total liquidity, including undrawn revolver availability, against a minimum cash threshold agreed with management or the lender.
- Every week, roll the model forward and produce a variance report that explains each material gap between forecast and actual.
| Forecast line | Source documents | Common mistake |
|---|---|---|
| Opening cash | Bank statements, treasury portal | Using the ledger balance instead of cleared funds |
| Customer receipts | AR aging, payment history by customer | Assuming customers pay on stated terms |
| Payroll | Payroll register, pay calendar | Missing employer taxes and benefit remittances |
| Vendor payments | AP aging, scheduled payment runs | Ignoring deposit or cash-in-advance demands from key suppliers |
| Debt service | Credit agreement, amortization schedule | Forgetting interest dates that fall mid-quarter |
| Professional fees | Engagement letters | Under-forecasting advisers, including any success fee due at a milestone |
| One-time receipts | Signed agreements, issued invoices | Counting a deal before it is signed |
13-week cash flow vs other forecasts
| Tool | Basis | Horizon | Question it answers |
|---|---|---|---|
| 13-week cash flow | Direct receipts and disbursements | 13 weeks, weekly | Can we pay what falls due? |
| Annual budget | Accrual profit and loss | 12 months, monthly | Will we hit our operating targets? |
| Statement of cash flows | Indirect, starting from net income | Historical periods | Where did cash come from and go? |
| Three-statement model | Accrual, linked statements | Several years | What can the business support and earn? |
| Adjusted EBITDA bridge | Normalized accrual earnings | Trailing twelve months | What is the recurring earning power? |
| Chapter 11 budget | Direct, approved by the lender and court | Usually tracks the same 13 weeks | Which spending is authorized during the case? |
In a chapter 11 case, the budget that governs what a debtor in possession may spend is commonly built from the 13-week model, so variances there carry real consequences.
Where data licensing proceeds belong in the forecast
Leave them out until terms are signed. A licensing payment is a single one-time receipt, and even after signature its date depends on the buyer selecting the data and the invoice going out. When a company licenses its records through SourceX, it receives one all-in price, paid once, typically within about 60 days of invoicing.
| Deal stage | Forecast treatment | Reason |
|---|---|---|
| Introduction made, qualification under way | Exclude entirely | The company may not qualify, and nothing has been agreed |
| Data inventory done, price and terms in negotiation | Exclude; mention as upside in the commentary | Nothing is binding until the company signs |
| Agreement signed, buyer selection pending | Keep out of the base case; show only in a sensitivity case | Timing depends on the buyer's selection |
| Buyer has selected the data and the invoice is issued | Include about 60 days after the invoice date, flagged as one-time | Payment typically lands within about 60 days of invoicing |
| Cash received | Record as actual and label it non-recurring | Keeps it out of run-rate receipts |
Lenders and buyers will also ask how a one-time license is treated in a diligence review; see non-recurring income in quality of earnings.
Cash timing and revenue timing are separate questions. How a license is structured can affect when it is recognized as revenue under ASC 606, which distinguishes a right to use licensed intellectual property from a right to access it, as Deloitte's revenue recognition roadmap explains. The 13-week model ignores that and records cash when it clears; take the profit and loss question to the company's auditors. This is general information, not legal, tax or financial advice.
Why the forecast matters to restructuring advisors who make introductions
The disbursement review is where records get lost. When a turnaround team cuts software subscriptions, decommissions servers or lets a legacy help desk lapse to save cash, years of operational history can disappear with them. Before a subscription line comes out of the forecast, ask whether the system's history has been exported and who holds the copy; a company whose archives were deleted cannot license them later.
The same weekly meeting is a natural place to mention licensing as a possible future receipt rather than a rescue. It suits companies with 50+ full-time employees at peak (contractors excluded), several years of documented operations across many systems, rights to the records and an authorized sponsor willing to engage. The who qualifies page lists the full baseline, and the company fit checker gives a preliminary, non-binding screen with no contact details required.
For an advisor who introduces the company, partners earn 25% of the eligible platform fees SourceX actually collects from the referred company's licensing deals, capped at $100,000 per referred company, payable only after the buyer pays and SourceX receives its fee. Rewards are not guaranteed, and advisers retained by an estate or a lender should check their engagement terms and disclosure duties before accepting any fee.
Illustrative example
Illustrative, fictional company: a 140-person freight brokerage is in a lender-led turnaround. The interim CFO's week-1 forecast shows liquidity dipping below the agreed minimum in weeks 9 to 11. The owner has already started a data licensing process for nine years of load, carrier and dispatch records, and the agreement is signed in week 4.
The CFO keeps the receipt out of the base case. The buyer selects the data and the invoice goes out in week 8, so the receipt enters the model as a one-time inflow around week 17, beyond the current window. The plan for weeks 9 to 11 still rests on collections and vendor terms, and the licensing receipt appears in the lender update only as upside after the forecast period.

Common questions
Why 13 weeks rather than a month or a year?
Thirteen weeks equals one quarter, which captures every payroll cycle, a full month-end close, quarterly tax payments and most interest dates, while staying short enough to forecast each large customer and vendor individually. Monthly forecasts hide mid-month cash troughs, and annual budgets are built on accrual profit, so neither shows whether payroll can be met in a specific week.
Who prepares and owns the 13-week cash flow?
Usually the company's CFO or controller owns it, often with a turnaround firm, interim CFO or financial advisor building and maintaining the model during a restructuring. Lenders and boards review it weekly or every other week. Ownership matters because the variance explanations must come from people who know why a customer paid late or a vendor demanded a deposit.
What is a variance report in a 13-week cash flow?
It compares last week's forecast with actual receipts and disbursements line by line and explains each material gap as either timing, which reverses in a later week, or permanent, which does not. Lenders often set covenants on cumulative variances, so a credible variance report matters as much as the forecast itself.
Can a signed data license support a lender forbearance request?
It can be mentioned, but it should not carry the liquidity plan. Until the buyer selects the data and an invoice is issued, the payment date is uncertain, and payment typically arrives within about 60 days of invoicing. Present it as a one-time upside case with clear assumptions, and let collections, cost actions and financing carry the base case.
Is a 13-week cash flow template enough for a turnaround?
A template gives the structure, but the value comes from the inputs: customer-level receipts, actual pay dates, vendor-by-vendor payment plans and a weekly variance discipline. Teams that spread last month's totals evenly across weekly columns lose the detail that makes the forecast useful. Start from the bank and build each line from source documents.
