How to Manage Cash Flow as a Tradesperson

Cash flow kills more trade businesses than bad work ever does. Here is a practical guide to keeping money moving in your business.

Most trade businesses do not fail because the work is bad. They fail because there is no money in the bank when wages, materials, or fuel need paying. You can be flat out busy and still go broke if the cash is not landing in your account on time.

Cash flow is simply the timing of money in and money out. Get the timing right and you can run a calm, profitable business. Get it wrong and every Friday becomes a panic.

Why cash flow is harder in the trades

Trade work has a brutal cash cycle. You buy materials before the job. You pay your team weekly or fortnightly. The client pays you 14, 30, or sometimes 60 days after the work is done. That gap is where businesses die.

Bigger jobs make this worse. A $ 40,000 bathroom build can swallow $ 18,000 in materials before you see a cent. Price every job properly with a deposit and progress payments and that gap shrinks fast. It helps to work the numbers through a free quote calculator so each stage payment is costed before you commit.

Get money in earlier

The single biggest lever is asking for money sooner. Not more money, just sooner. Most clients will happily pay a deposit and progress payments if you ask up front and write it into the quote.

Always take a deposit

On any job over $ 500, ask for a deposit. 25 to 50 percent is normal in plumbing, electrical, and building. Build the deposit into your standard quote so you never forget it. Start from one of the free quote templates and the deposit line is already there. The client signs the quote, the deposit lands, you order materials.

Bill at milestones, not the end

Break larger jobs into stages. Rough-in done, invoice. Fix-out done, invoice. Final, invoice. You do not wait six weeks for one big payment. The money flows as the work flows.

Invoice the day the work is done

An invoice sent five days late gets paid five days late. Send it from your phone the moment you leave site. Whatever your line of work, the directory of trades shows how a mobile quoting and invoicing workflow lets you generate and email the invoice before you have packed the van.

Slow money out without burning suppliers

While you pull money in faster, push your own payments out without damaging relationships. The trick is to use the supplier terms you already have, not stretch them.

• Open trade accounts with your top three suppliers. 30 day terms is standard.
• Pay on the due date, not the day the invoice arrives.
• Negotiate longer terms once you have a track record. 45 days is achievable after a year.
• Use a business credit card for fuel and small purchases. You get up to 55 days of free money.
• Never miss a supplier payment. Once you do, you lose terms and pay cash for everything.

Build a buffer (and protect it)

A cash buffer is the difference between sleeping at night and dreading every Monday. The target is simple. Hold one month of fixed costs in a separate account. Wages, rent, vehicle, insurance, software, accountant. Add it up and bank that amount.

Get there by skimming. Every invoice that lands, move 5 to 10 percent into the buffer account before you spend a cent. You will not miss it. After six months you have a real safety net.

Know your numbers weekly, not yearly

Most tradies look at their numbers when the accountant calls in July. By then the damage is done. You need three numbers in front of you every Monday morning.

• Cash in the bank right now.
• Money owed to you (debtors) and how old each invoice is.
• Money you owe out in the next 30 days (suppliers, wages, tax).

If money owed to you is bigger than money you owe out, you are fine. If it is the other way around, act this week. Chase the oldest invoices, slow a non urgent purchase, ring the client whose deposit is due.

A real example

Take a sparky doing a $ 12,000 switchboard upgrade. Old habit: order $ 4,500 in gear on the trade card, do the work over two weeks, invoice on completion, get paid 28 days later. Total time between paying for materials and being paid: 42 days. That is $ 4,500 of your money tied up.

New habit: 30 percent deposit ($ 3,600) before any materials are ordered. Materials go on 30 day account. Progress invoice ($ 4,800) at switchboard install. Final invoice ($ 3,600) on completion. By the time the supplier bill is due, you have collected $ 8,400. You finish the job cash positive instead of cash negative.

Common cash flow mistakes

• No deposits because you feel awkward asking.
• Quoting low to win the job, then losing money on every one.
• Mixing personal and business money in one account.
• Buying a new ute on finance during a quiet quarter.
• Not putting GST and tax aside as it comes in.
• Letting one invoice sit unpaid for 60 days without a phone call.

The bottom line

Cash flow is not about earning more. It is about timing. Take deposits, invoice fast, chase early, hold a buffer, and watch your numbers weekly. Pair that with proper pricing and a tidy quoting system and the panic disappears.

Get the timing right and you can run a calm, profitable business that handles quotes, invoices, and reminders in one place.
