CashFlow Compass — 13-Week Cash Flow Forecast & Runway Planner

See the week your cash runs short while there is still time to act

A monthly profit and loss statement can look healthy while week three of the month is empty. Salaries leave on the 1st, your biggest customer pays on the 20th, GST goes out after month end — and none of that timing shows up on a monthly view. CashFlow Compass turns your monthly sales and costs into thirteen weekly closing balances. Each of your revenue lines carries its own collection lag and bad-debt percentage; each cost line carries its own payment lag. The engine shifts every line into the week the money actually moves, adds GST output minus input with your filing lag, folds in one-off capex and refunds, and prints the answer: opening cash, closing cash, your buffer, OD headroom and an OK / BELOW BUFFER / NEGATIVE status for each week. A dashboard turns it into one plain-English sentence, twelve numbers and two charts. A scenarios tab runs Base, Slow and Stress as three complete engines, so you can price a bad quarter before you live it. Macro-free, offline, and it opens in Google Sheets.

The Problem With a Monthly View

Profitable on paper, short of cash on Friday

A business can be profitable and still miss payroll. The two things that decide whether you make it through the month are timing and lags: when customers actually pay you, and when you actually pay everyone else. A monthly profit and loss statement averages all of that into one number and quietly hides the two weeks where the account is thin.

Most small businesses run the forecast in their head. The result is a decision made on a bad morning — a supplier paid late, a discount given away, an overdraft drawn at the worst possible rate. Thirteen weeks is the horizon that fixes this. It is one quarter: long enough to see a squeeze coming, short enough that the numbers are still close to true. You can plan for week 4 on the 1st of the month; you cannot do much about week 4 once week 4 has arrived.

CashFlow Compass exists to make that quarter visible in about ten minutes of setup, using the numbers you already know — your monthly sales, your monthly costs, and how long each of them takes to move through the bank.

What Is Inside the Workbook

Seven tabs, each doing one job

Setup — nine inputs

Business name, the start Monday, opening bank balance, the buffer you refuse to go below, your undrawn CC/OD limit, and four GST settings: registered or not, the sales rate, the purchase rate you can claim, and your filing lag in weeks. Nothing else on this tab needs editing.

Assumptions — the lags that matter

Six revenue lines and twelve cost lines, each with a monthly amount, an annual growth rate, and its own lag in weeks. Revenue lines also carry a bad-debt percentage; cost lines carry fixed-or-variable and whether input GST credit is claimable. Six one-off slots take capex, refunds and advances with the week they land.

Forecast-13W — the engine

Thirteen week columns with real dates, then sales invoiced, collections after lag and bad debt, costs billed, payments after lag, GST accrued and paid, one-offs, total money in, total money out, and the four rows that answer the question: opening cash, closing cash, your buffer, OD headroom — plus a per-week status.

Dashboard — the sentence

One gold line at the top that reads your own numbers back to you in plain English: CLEAR, WATCH or ALERT, with the week and the rupee amount. Below it, twelve metrics including lowest closing balance, the week it happens, extra cash needed and GST payable. Then five health checks and two charts.

Scenarios — three full engines

Not an estimate: three complete thirteen-week engines driven by four dials each — sales multiplier, cost multiplier, extra collection delay, extra payment delay. The Slow case is 85% of plan with two extra weeks of collection; the Stress case is 70% with four extra weeks and stretched suppliers. Each returns lowest cash, gap and verdict.

Actual vs forecast — the honesty tab

Type what really hit the bank each Monday and the sheet returns the variance on inflows and outflows, the real closing balance, and a forecast-accuracy percentage. Below 85% on the inflow side means your collection lags are optimistic, and the sheet says so.

START HERE — four minutes

The conventions the model uses, the order to fill the tabs, the three habits that make a forecast worth having, the colour code, and what the workbook deliberately does not do.

A Look at the Dashboard

The example workbook, as it opens

CLEAR: closing cash stays above your buffer in all 13 weeks. The lowest point is ₹3,39,863 in week 4 — a reasonable week to approve a planned spend or prepay a supplier.

What You Get for ₹249

One ZIP, five files, nothing to subscribe to

Two workbooks

CashFlow-Compass-Template.xlsx — blank, ready for your numbers. CashFlow-Compass-Example.xlsx — the same seven tabs filled in for a fictional business, so you can see a tight week and a clear week before you trust your own.

Quick start and manual

START-HERE.txt walks you through setup in ten minutes, step by step. README.txt explains how every calculation works, how to read the signal, the Monday ritual, Google Sheets steps and a troubleshooting list.

Licence

LICENSE.txt — one business or one professional, unlimited internal use, unlimited years, no resale or redistribution. Eight clauses, plainly written.

Built to be audited

No hidden steps. The engine is one row per line per week, all visible: sales row, collections row, cost row, payments row. You can trace any closing balance back to the assumption that produced it, and every formula is unlocked if you want to change one.

Built to be edited

No password protection and no macros, so the file will not be blocked by a corporate mail filter or a security warning. Insert a row, rename a line, add a seventh revenue line — the totals are SUM ranges, not fixed lists.

Who It Is For

If money comes in later than it goes out, this is your sheet

🏪

Traders, distributors and retailers

Stock bought on 14-day credit, sold to distributors on 45-day terms, salaries on the 1st. The mismatch is the business model — this sheet makes it visible week by week.

🏗️

Contractors and project businesses

Milestone billing, retention held back, material bought up front. The one-off table takes the machine you must buy in week 4 and the advance that arrives in week 2.

💻

Agencies and professional firms

Retainers billed at month start, paid in seven days; salaries and rent on the 1st; a big client who pays in sixty. Run the Slow case before you hire.

🏥

Clinics, studios and local services

Cash at the counter, insurance or corporate panels paying late, equipment EMIs on a fixed date. Fixed versus variable is a column, so the dashboard splits both.

📊

Accountants and virtual CFOs

A structured thirteen-week file you can fill from a client's Tally export in twenty minutes, and hand back as a PDF with two charts on it. Multi-client licence available.

🚀

Founders preparing for a lender

Banks and NBFCs ask for a cash flow projection, not a P&L. This gives you the weekly closing balances, the headroom figure and a printed dashboard to attach.

How It Works

Setup in ten minutes, ten minutes every Monday after that

The maths, so you can trust it. Each monthly figure is divided by 4.33 to reach a weekly figure, then grown at your annual rate week by week. A revenue line with a three-week collection lag contributes nothing in weeks 1 to 3, and in week 4 collects what was invoiced in week 1, less the bad-debt percentage you set. Costs work the same way with the payment lag. GST is output tax on invoiced sales minus input credit on the cost lines you marked claimable, with the positive part paid after your filing lag. Headroom is closing cash plus undrawn OD limit minus your buffer — the amount you could absorb before you break your own floor.

The weekly ritual. Every Monday: type last week's real money in and out on the actuals tab, glance at the accuracy score, move the start date forward one Monday, and read the new signal line. Four weeks of that and the forecast starts being right, which is when it becomes worth something. The manual says this too, because a forecast you do not update is a decoration.

The order of moves when it says WATCH or ALERT. Chase the three largest overdue invoices. Offer a small early-payment discount on the biggest one. Shift a non-critical payment run by seven days — never statutory dues, never payroll. Draw the OD line before you need it rather than after. Delay growth spend last. The workbook names the week and the gap; the manual lists the levers; the decision stays yours.

File Format & Compatibility

Plain .xlsx, no lock-in, no macros

Format

One ZIP containing two .xlsx workbooks (Office Open XML), a quick-start text file, a full manual and a licence. Unzips on Windows, macOS, Linux, Android and iOS with the built-in tools — no extra app needed.

Works in

Microsoft Excel 2016 or later on desktop, Microsoft 365, Excel for the web, LibreOffice Calc 7 and later, and Google Sheets. Both workbooks are tested in Excel and LibreOffice; the Google Sheets steps are in the manual.

No macros, no add-ins

Every calculation is a standard formula — SUM, INDEX, SUMIFS, SUMPRODUCT, IF. Nothing needs enabling, no security warning appears, and the file opens in a corporate environment that blocks .xlsm.

Printing and PDF

Every tab is set to A4 with fit-to-width, so the dashboard prints on one landscape page with both charts — ready to sign and hand to a bank or an investor.

Units and format

Amounts in whole rupees with Indian grouping (12,50,000). Dates in dd-mmm-yy. Thirteen weeks starting on the Monday you choose.

What it is not

Not accounting software and not a filing tool. It does not compute GST returns, TDS, PF/ESI or loan covenants, and it is not financial, tax or legal advice. Your forecast is only as good as the assumptions you enter — the manual is honest about that.

Licence

One purchase, one business, forever

Your purchase covers use by one business or one practising professional, on any number of your own devices, for as long as you like, with no renewal. You may edit every cell, print or export the output for your bank, lender, investor or accountant, and share that printed output freely. You may not resell, redistribute or republish the workbooks, upload them to a file-sharing site or a template marketplace, or include them in a paid course or client deliverable — consultants and CAs using it with clients need one licence per client business. Full terms are in LICENSE.txt inside the ZIP.

Frequently Asked Questions

Is this an ebook or a working file?

A working file. The ZIP contains two macro-free .xlsx workbooks — one blank template and one filled-in example — plus a quick-start, a full manual and a licence. You open it in Excel or Google Sheets and type your own numbers.

Do I need to know Excel formulas?

No. You type into gold cells only: your opening cash, your buffer, your revenue and cost lines with their lags, and any one-off items. Every calculation, chart and colour code is already built. If you want to change a formula you can — nothing is locked or password-protected.

Why thirteen weeks and not twelve months?

Because a monthly view hides the bad week. Salaries leave on the 1st, your biggest customer pays on the 20th, GST goes out after month end — a month can close healthy while week three is empty. Thirteen weeks is one quarter: long enough to see a squeeze coming, short enough that the numbers are still roughly true.

How does it handle GST?

It computes output GST on your invoiced sales at the rate you enter, subtracts input credit on the cost lines you mark as claimable, and pays the positive net amount after the lag you set. Negative weeks are held at zero rather than carried forward, which keeps it simple. Your actual liability comes from your returns, not from this sheet.

Does it work in Google Sheets?

Yes. Upload the .xlsx to Drive, open it, then File > Save as Google Sheets. Formulas, number formats, dropdown validation and both charts carry over. After import, re-apply the custom rupee format on a few cells and re-point the chart titles if Google has renamed the ranges — the manual explains both in one line each.

What is the difference between the template and the example?

They are the same seven-tab workbook. The example is filled in for a fictional trading and service business called Sunrise Traders, so you can see a real forecast with a tight week before you type anything. The template is blank. Use the example to learn, the template to work.

Will it tell me how to fix a cash shortfall?

The signal line names the week and the size of the gap, and the manual lists the order of moves that usually works: chase the three largest overdue invoices, offer an early-payment discount, shift a non-critical payment run by a week, draw the OD line before you need it. It does not decide for you, and it is not financial advice.

How many businesses can use one purchase?

One business or one practising professional, on any number of your own devices, for as long as you like. Consultants and CAs using it with clients need one licence per client business — write to us for a multi-client licence.

How do I get the files after payment?

After a successful payment on Razorpay you land on a thank-you page with a download button. Click it and the ZIP is yours immediately. There is no account to create and no email to wait for.

Is it a subscription?

No. One payment of ₹249, no renewal, no expiry, no per-user fee. You keep both workbooks and can run the forecast for as many years as you like.

Can I get a refund?

Digital products are non-refundable once downloaded. But if a file arrives corrupted or will not open, or you were charged incorrectly, email lonefaisal977@gmail.com within 7 days and it will be replaced or resolved.
