Cash Flow Forecast for Solo Tradesmen: Keep Your Business Strong
You're a skilled roofer, plumber, or tiler ready to work for yourself. Great! But leaving a steady paycheck means *you* are now responsible for cash flow. Many self-employed tradespeople, even good ones, struggle because they run out of cash, not because they aren't profitable on paper. Your tools and skills are top-notch; your cash management needs to be too. The 13-week rolling cash flow forecast is your simple 90-day map to make sure your bank account never hits empty.

The Quick Answer
As a self-employed plumber, roofer, or flooring installer, you *must* know your cash position. Build a 13-week (90-day) rolling cash flow forecast. Update it every week. This forecast shows your projected weekly cash balance. It helps you see cash shortfalls *before* they happen. This means you can act in time: chase down unpaid invoices from that recent drywall job, hold off on buying a new tile saw, or tap your business line of credit. Don't wait until your bank account is empty to react.
Why 13 Weeks?
For solo trades like plumbing or roofing, 90 days is perfect. Your projects usually last days to a few weeks, and customer payments often clear 30-60 days after you finish the work. This 90-day view is long enough to see if that big flooring job will leave you short on cash before final payment, but short enough to be realistic about when you'll actually get paid for a hot water heater install or a roof repair. Shorter forecasts (monthly) don't give you enough time to react. Longer ones (annual) are often guesswork when you're just starting out.
Building the Forecast: Cash In
For a self-employed tradesperson, your cash inflows mostly come from customer payments. Think about: * **Customer Invoices:** When do customers *actually* pay you for that bathroom renovation or electrical rough-in? Not just when you send the invoice. If Mrs. Smith usually pays 15 days after you finish tiling, mark that down. If a commercial client takes 45 days, factor that in. * **Material Deposits:** Sometimes clients pay a deposit for materials upfront. When does that cash hit your bank account? * **Loan Proceeds/Owner Cash:** Did you take out a small business loan to buy a new work truck, or put in some of your own savings to get started? When does that money arrive? Remember: if you have a few clients who are always slow, like 1 in 5 taking an extra two weeks for a roofing payment, reflect that delay in your forecast.
Building the Forecast: Cash Out
As a solo tradesperson, your cash outflows include: * **Your Own Paycheck:** Even if it's just a draw, when do *you* pay yourself for your living expenses? * **Vehicle Costs:** Truck payments, fuel for your work van, maintenance. When are they due? * **Tools & Equipment:** Payments for your new pipe threader, tile cutter, or nail gun. Tool repair costs. * **Materials:** Plywood, copper pipe, bags of mortar, wiring. When do you pay your suppliers (e.g., Home Depot, local lumber yard)? * **Insurance:** General liability, workers' comp (if you hire even temporary help), health insurance premiums. When do these clear your bank? * **Software & Subscriptions:** Your invoicing software (like QuickBooks Self-Employed), website hosting. * **Loan Payments:** Any payments for that business loan or equipment financing. * **Marketing/Permit Fees:** Local permits for jobs, online ads. List every payment for the week it *leaves your bank account*, not when you get the bill. Your credit card bill due on the 25th might clear your bank on the 27th.
Reading the Forecast: What to Look For
The goal is to see your ending cash balance each week. Watch for: * **Red Flag Weeks:** Any week where your projected cash balance drops below your absolute minimum. For a solo tradesperson, this 'minimum' might be enough to cover your own basic living expenses, truck payment, insurance, and the next week's essential materials. Maybe $2,000-$3,000 to keep the lights on and the truck running, even if you don't get paid. * **Cash Flow Direction:** Is your weekly balance generally going up, staying flat, or slowly dropping? If you're busy with new roofing jobs but your cash isn't growing, you might be letting invoices sit too long. * **Slow Season Dips:** Do you know that late winter is slow for outdoor work, or that August is slow for general contractors when clients go on vacation? Plan for these predictable slow periods by making sure your cash reserves are built up beforehand.
Interventions: What to Do When You See a Gap
When your forecast shows a cash gap, here's what to do: * **60+ Days Out:** * **Collect Faster:** Send your final invoice the day the plumbing job finishes. Offer a 2% discount if a client pays within 5 days. Follow up on that 30-day overdue invoice for the flooring project. * **Cut Spending:** Hold off on buying that new power washer or a fancier estimating software. Delay ordering non-urgent material for a future job. * **Talk to Suppliers:** Can you get 60-day payment terms instead of 30-day terms from your drywall supplier? * **30-60 Days Out:** * **Use Credit:** Draw on your business credit card or line of credit to bridge the gap. * **Negotiate:** Call your main material supplier. Explain you need an extra 10-15 days on an upcoming payment. Most will work with you if you're proactive. * **Under 30 Days Out:** * **Survival Mode:** Pay your most critical bills first: your own living expenses, truck payment, insurance, and taxes. * **Communicate:** Call your utility company, your insurance provider, or your suppliers *before* you miss a payment. Don't ghost them; a heads-up usually buys you goodwill and more time.
How to Get Started
It's easier than it sounds. * **Build It:** Create a simple spreadsheet. Label columns 'Week 1' to 'Week 13'. Rows include 'Starting Cash,' 'Cash In (Customer Payments, Deposits),' 'Cash Out (Your Pay, Truck, Materials, Insurance),' 'Net Cash Flow,' and 'Ending Cash.' * **Start with Today:** For Week 1, put in your *actual* cash balance from your business bank account today. * **Forecast:** For Weeks 2-13, fill in your expected cash inflows based on your project schedule and when you expect client payments to clear. Then add your expected outflows – your truck payment, material bills, insurance, etc. * **Update Weekly:** Every Monday morning, take 15-20 minutes. Update Week 1 with actual numbers, shift all other weeks left, and add a new Week 13. This simple habit keeps your finger on the pulse of your 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.
