How to Set Up a 12-Week Cash Flow Forecast for Your Newly Acquired Business

Acquiring a business is an exciting milestone, but the hard work doesn’t end there. One of the most critical steps post-acquisition is ensuring you have a solid grip on your business’s cash flow.?

This is where a 12-week cash flow forecast comes into play. It helps you to understanding your cash position, anticipate challenges and making informed decisions.

If you’ve just acquired a business and want to take control of its financial health, this guide will walk you through setting up a 12-week cash flow forecast.

Why a 12-Week Cash Flow Forecast Is Essential

Before diving into the "how," let’s quickly discuss the "why."

A 12-week cash flow forecast:

?? Provides visibility: It helps you understand when cash is coming in and going out, allowing you to spot potential cash shortfalls before they happen.

?? Improves decision-making: It gives you the insight needed to make smart, timely decisions, whether that’s managing expenses, securing financing or planning growth initiatives.

?? Builds confidence: When you know where your cash stands, you feel more confident in your business operations, allowing you to focus on other areas of growth.

Now that we understand the importance, here is a simple 6-step process for you…

Step 1: Gather Your Financial Data

Start by collecting all the necessary financial information. You’ll need:

?? Bank statements from the past few months

?? Accounts receivable (money owed to you) and accounts payable (money you owe)

?? Recurring expenses, such as rent, utilities, payroll, insurance, and supplier costs

?? Sales forecasts and revenue projections

Having all this information in hand will allow you to build an accurate and reliable forecast.

Step 2: Set Up Your Cash Flow Spreadsheet

To create a 12-week cash flow forecast, you can use a simple spreadsheet tool like Excel or Google Sheets.

Here is how to set it up:

1. Create Columns: Label each column with the week number (e.g., Week 1, Week 2, etc., up to Week 12).

2. List Rows:

? Opening Cash Balance: This is your starting cash for each week.

? Cash Inflows: List all expected cash receipts, such as sales revenue, accounts receivable collections, loans, or other sources of cash.

? Cash Outflows: List all expected cash payments, including rent, payroll, utilities, loan repayments, and supplier payments.

? Net Cash Flow: Calculate the difference between cash inflows and outflows for each week (Cash Inflows - Cash Outflows).

? Closing Cash Balance: Add your net cash flow to the opening balance to determine your closing cash balance for the week, which will also be the opening balance for the next week.

Step 3: Estimate Your Cash Inflows

Estimating your cash inflows accurately is crucial.

Start with your sales forecasts and break them down into expected weekly receipts. Consider any outstanding invoices and when you realistically expect them to be paid.

Be conservative with your estimates.

Assume that payments might take longer than expected, especially if you are still establishing relationships with your clients post-acquisition.

Step 4: Calculate Your Cash Outflows

Next, list all your cash outflows.

Be thorough and include every expected payment:

?? Fixed expenses (rent, payroll, insurance)

?? Variable expenses (supplies, raw materials)

?? Loan repayments or interest payments

?? Any one-time costs or investments you plan to make during the 12-week period

Double-check that you haven’t missed anything—cash flow forecasting is only as accurate as the information you put in.

Step 5: Review and Adjust Your Forecast

Once you’ve filled out your spreadsheet, take a step back and review it. Does the cash flow look stable, or are there weeks where cash might run tight?

Look for potential issues such as:

?? Weeks where outflows exceed inflows (creating a cash shortfall)

?? Heavy expense weeks, like payroll or large supplier payments, that might need better planning

If you notice issues, consider strategies to manage them:

?? Delay non-essential expenses to even out cash flow.

?? Negotiate payment terms with suppliers to spread costs over a more extended period.

?? Speed up accounts receivable collections by offering early payment discounts.

Step 6: Monitor and Update Your Forecast Weekly

A cash flow forecast isn’t a "set it and forget it" tool. Update it every week with actual figures to see how your forecast matches reality.

This process allows you to:

?? Adjust projections based on recent performance.

?? React to any unexpected cash flow changes promptly.

?? Identify patterns and refine your forecasting skills.

Tips for Keeping Your Forecast Accurate

1. Be conservative with your estimates—overestimating revenue or underestimating expenses can lead to surprises.

2. Stay proactive by maintaining strong communication with clients and suppliers to ensure payment timelines are as expected.

3. Use technology—cash flow management software like Fathom can help automate parts of the process, reducing the risk of human error.

Final Thoughts

Setting up a 12-week cash flow forecast is an essential task for any new business owner. It might seem daunting at first, but with the right approach, it becomes a powerful tool for navigating the critical first months after acquisition.
