Cash Flow Management for Handyman & Home Services: Your 13-Week Forecast
Plenty of home service businesses, from independent handymen to new HVAC contractors, struggle with cash, even when profitable. You might be invoicing for a big remodeling job, but if you're waiting 45 days for payment while paying for lumber, permits, and your crew today, your bank account can quickly empty. The 13-week rolling cash flow forecast is the essential tool for your trade. It gives you a 90-day heads-up on your cash position, updated weekly, so you always know where you stand.

The Quick Answer
Build a 13-week (90-day) rolling cash flow forecast. Every week, update it. Add the new Week 13 and remove the week you just finished (Week 1). This forecast shows your bank balance each week. It helps you spot cash shortages *before* they hit. Then you can act fast. Maybe push customers to pay for that kitchen remodel sooner. Or delay paying for new drywall until you get paid. Or use your business credit line for a new air compressor. You get enough time to fix things.
Why 13 Weeks?
Why 90 days (13 weeks) is key for your trade: It's long enough to see problems brewing for that bathroom remodel or HVAC installation. But it's short enough that you can guess pretty well when customers will pay for jobs, or when you need to pay for copper piping or a sub-contractor. Annual forecasts are too vague. Monthly ones don't give you enough warning to adjust for big material orders. The "rolling" part means you *always* have a 90-day view, not one that shrinks over time.
Building the Forecast: Cash In
Your cash coming in comes from a few places. * **Customer Payments:** This is usually when clients *actually* pay you for that new deck or electrical upgrade, not just when you send the bill. If you require a 50% deposit upfront for big jobs, mark that down. If your average client pays 45 days after a handyman job is done, shift your invoice dates 45 days forward to predict when the money hits your bank. Don't forget, some clients will be late. If 10% of your remodel payments are 60+ days, factor that in. * **Recurring Work:** Maybe you have a few small maintenance contracts. * **Other Money:** Money from selling old tools, new business loans, or cash you put into the business yourself. For each week, guess when and how much cash you'll get based on your real experience.
Building the Forecast: Cash Out
Your cash going out includes these common items: * **Payroll:** Your crew's wages, non-negotiable. Don't forget your own salary. * **Rent & Fixed Costs:** If you have a shop or office, this is a set cost. * **Materials & Supplies:** When do you pay for lumber, paint, copper wire, HVAC parts? This is crucial. If you pay your supplier on Net 30 terms, make sure you mark the week the payment leaves your account. * **Sub-contractors:** When do you pay the plumber or electrician you hired for a big job? * **Vehicle Costs:** Truck payments, fuel, maintenance, insurance. * **Tools & Equipment:** Payments for that new concrete mixer or a repair on your power washer. * **Permit Fees:** For bigger jobs. * **Software & Marketing:** Costs for your scheduling app, QuickBooks, or local advertising. List every payment for the exact week it leaves your bank account. The date your accounting software *says* you owe it might be different from when the cash actually goes out.
Reading the Forecast: What to Look For
Your forecast will show your cash balance at the end of each week. Here's what to watch for: * **Red Weeks:** Any week where your cash goes below your "safe" limit. For a home service business, this might be enough to cover 3-4 weeks of payroll, fuel, and quick material buys. * **Cash Flow Direction:** Is your ending balance going up, staying even, or dropping? If you're getting more jobs but your cash isn't growing, it often means you're not collecting payments fast enough from clients. You're doing the work, but the money isn't hitting your bank. * **Slow Times:** Do you know that late winter is slow for outdoor work, or summer brings fewer interior remodels? Spot these predictable slow spots. Have your business credit line ready *before* you're scrambling for cash.
Interventions: What to Do When You See a Gap
When you spot a cash problem in your forecast, here’s how to act: * **More Than 60 Days Out:** * **Get Paid Faster:** For new jobs, ask for bigger upfront deposits or more progress payments. For current jobs, send invoices the *day* the work is done. Offer a small discount (like 1-2%) if clients pay their final remodeling invoice within 5 days. Call clients who are 15 days late. * **Hold Off on Spending:** Can that new saw or drill press wait a month? Delay it. * **Talk to Suppliers:** Can your lumber or electrical supplier give you Net 45 instead of Net 30 payment terms on your next big order? * **30-60 Days Out:** * **Use Your Credit Line:** If you have a business credit line, draw on it *before* you're desperate. * **Supplier Plans:** Talk to your biggest material suppliers. Can you pay half your bill now and half in two weeks? * **Delay Hiring:** Hold off on bringing on that new apprentice or helper if possible. * **Under 30 Days Out:** * **Must-Pays First:** Your crew's payroll, your shop rent, and taxes come first. Always. * **Talk to Suppliers Early:** If you *can't* pay your hardware or plumbing supplier on time, call them *before* the due date. Most would rather work out a plan than be surprised.
How to Get Started
* **Set Up Your Spreadsheet:** Use a simple spreadsheet program like Excel or Google Sheets. Put "Week 1" through "Week 13" across the top. Down the left side, list: * Starting Cash * Cash In (Client Payments, Other) * Cash Out (Payroll, Materials, Sub-contractors, Fuel, Rent, etc.) * Net Cash Flow (Cash In minus Cash Out) * Ending Cash Balance * **Fill in Week 1:** Use your actual bank balance from this morning as your "Starting Cash." Then list all the money that *actually* came in and went out this past week. * **Forecast Weeks 2-13:** * **Cash In:** Look at your open invoices in QuickBooks or your client schedule. When are those remodeling payments or repair job invoices *expected* to hit your bank? * **Cash Out:** Look at your upcoming bills. When are those material supplier invoices due? When do you pay your sub-contractors or your crew? When is your truck payment due? * **Update Weekly:** Every Monday morning, take 15-20 minutes. Drop the oldest week, add a new Week 13. Update with fresh info. This weekly check-in is where you gain real control over your business cash.

FREQUENTLY ASKED QUESTIONS
What is a healthy cash reserve for a small business?
Most financial advisors recommend 3-6 months of operating expenses as a cash reserve. For businesses with predictable recurring revenue, 3 months is sufficient. For businesses with lumpy or seasonal revenue, 6 months provides a meaningful buffer.
How do I speed up accounts receivable collections?
Send invoices the day work is complete, not at month-end. Offer 2/10 net 30 terms (2% discount if paid within 10 days). Send payment reminders at 15 days past due, not 30. Accept ACH and credit card payments to remove friction. For chronic late payers, require deposits before starting work.
Should I use a cash flow forecast or a profit and loss statement to manage my business?
Both. The P&L tells you whether your business model is working. The cash flow forecast tells you whether you can pay your bills next month. Profitable businesses can and do run out of cash — especially during growth phases when you are investing ahead of revenue.
