In the trades, cash flow is everything.

Even if your schedule is packed, you can still face problems if payments don’t arrive when you need them.

The U.S. Small Business Administration estimates that 82% of small businesses fail because of cash flow issues.

I’ve seen it firsthand with electrical, HVAC, and plumbing contractors. The problem is the gap between when they are paid and when they get paid.

The reality in this business is simple but brutal. You pay for materials and labor today, but you don’t get paid for 30, 60, sometimes 90 days (or more if you have a commercial side to your business). That gap kills profit.

So let’s go through a practical, boots-on-the-ground strategy to stretch your payables, reduce your costs, and take back control by using your local supply house and the Ramp corporate card.

Step 1: Review the Terms You Already Have.

Most contractors already have accounts with their local supply houses. Whether it’s electrical distributors, plumbing wholesalers, or HVAC suppliers, their terms likely look like this:

• Net 30 is standard
• Longstanding relationships can get you Net 60 to Net 90

In practice, I’ve seen that over 70% of contractors don’t fully leverage extended terms, either because they pay early out of habit or because of poor cash flow management.

The missed opportunity is when your supplier gives you 60 days, which is essentially free financing. If they give you 90 days, even better, you’re getting materials installed and invoices collected before your bill is due.

Now it gets interesting.

Step 2: Layer in Ramp to Extend Payables Even Further

Ramp is a charge card that works differently from a typical bank card.

Key features include:

• 1.5% cash back on every purchase
• No personal guarantee required
• Full balance due monthly (like Amex-style cards)
• Detailed spend controls and visibility

You gain more control over your spending when you control the timing. Add a layer to your supplier relationships to gain control over every transaction.

It will likely go something like this:

You buy materials with your Ramp card, and your supplier still offers its usual 30-90-day terms. Ramp only requires payment about 30 days after your statement closes. That setup gives you time to complete the job, send the invoice, and get paid before the bill is even posted to your account.

• Day 0: Buy $10,000 in materials
• Day 30: Supplier invoice posts
• Day 30–90: Supplier payment due
• Day 60–120: Ramp statement due

Depending on how you time it, you can push your cash outflow to 60–120 days after the initial purchase.

And to make it even better, you’re earning 1.5% cash back, which on $250,000/year in materials equals $3,750 straight back to your bottom line.

Step 3: Turn Everyday Purchases Into Real Profit

When it comes to profit margins, in a good year, most residential contractors operate at 8%–15% net profit margins.

So when Ramp gives you 1.5% back, that’s not pocket change.

Let me use an example:

• On $500,000 in annual material spend
• 1.5% cash back = $7,500

That’s equivalent to needing $50,000–$90,000 in additional revenue just to generate the same profit.

And unlike chasing more jobs, this doesn’t require:

• Hiring more techs
• Buying more trucks
• Increasing marketing spend

It’s just smarter purchasing.

Step 4: Empower Your Field Techs Without Losing Control

One of the biggest operational headaches is field purchasing. A tech gets to a job, realizes they’re missing a fitting, breaker, or control board, and now you’ve got delays.

Traditionally, you have two bad options:

• Send them back to the shop (lost time)
• Let them use personal cards or petty cash (lost control)

Ramp provides an effective solution.

You can:

• Issue individual cards to each field tech
• Set spending limits by role or job
• Restrict purchases to approved vendors

According to industry surveys, uncontrolled field spending can account for up to 5% leakage in project costs.

With Ramp:

• Techs can make spot purchases instantly
• You see every transaction in real time
• Receipts and job costing stay organized automatically

This provides control without hindering your team’s efficiency.

Step 5: Work with Your Local Suppliers

Suppliers rarely object to card payments, especially from regular customers. Paying by card can strengthen your relationship, as suppliers receive faster payments and benefit from simplified accounts receivable.

Some suppliers may charge processing fees, but these can often be reduced or waived through negotiation. Consistent volume, loyalty, or early payment agreements can encourage flexibility. Even with a small fee, the cashback benefit often outweighs the cost.

This structure benefits both parties: you gain extended payment terms, your supplier receives reliable payments, and the relationship becomes more stable.

Step 6: Stacking Benefits for Maximum Impact

Combining supplier terms with Ramp provides a significant cash flow advantage. Suppliers may offer 30 to 90 days to pay, and Ramp adds approximately 30 more days. This can extend your cash outflow to 120 days, allowing you to complete projects and collect payment before your bills are due.

You also reduce direct costs through approximately 1.5% cash back on spending, which accumulates significantly over the year. For contractors with tight margins, this can meaningfully improve profitability without altering pricing or sales strategies.

This approach also streamlines financial processes, improves control over field purchases, and enhances spending visibility. Since materials often represent over half of project costs, even minor improvements can significantly impact your bottom line.

And it isn’t a complex change. You can set this up quickly and start seeing the benefit almost immediately.

Step 7: Don’t Make These Common Mistakes

Before implementing this strategy, consider these important lessons:

• Don’t lose track of payment timing.
• Extending payables is effective only with disciplined management. Missing a Ramp payment can quickly negate your gains.
• Don’t overextend your purchasing.
• Extended payment terms should not lead to excessive inventory purchases.
• Communicate with your supplier.
• Build trust by letting them know how you’re planning to pay.
• Start with one crew or job.
• Test the system with a small team before expanding company-wide.

Failures with these systems typically result from poor execution rather than flaws in the system itself.

This Is About Control

After 30 years in this industry, I have found that successful contractors are not always the busiest, but those who effectively manage their cash flow.

Using Ramp with your local supply house is not about financial maneuvering. It is about:

• Giving yourself breathing room
• Turning everyday purchases into profit
• Running a tighter, more disciplined operation

If your annual material spend exceeds $200,000, this strategy warrants serious consideration. While it is effective at lower volumes, the benefits increase as your purchasing grows.

What are Your Next Steps?

If you want to put this into action, here’s what I’d do this week:

1. Review your supplier terms
2. Confirm whether you’re at Net 30, 60, or 90—and push for better if you can.
3. Run your annual material spend
4. Multiply it by 1.5% to see your potential savings.
5. Check out Ramp
6. Visit their site and see if you qualify: https://www.tempestamedia.com/ramp-corporate-card/
7. Pilot with one crew
8. Issue cards, set limits, and track results for 30 days.
9. Measure cash flow improvement
10. Look at how much longer you’re holding onto cash—and what that allows you to do.

If you implement this right, you’re building a stronger, profitable business.

And in this industry, that’s what separates the companies that survive from the ones that scale.
