Why Contractors Need Specialized Payment Tools
Contractors face unique challenges: you’re often on a job site, you need to send estimates that turn into invoices, and you need to get paid before buying materials for the next project. A standard payment processor doesn’t help you manage a project from bid to final payment. According to Joist and One Click Contractor, the best solutions combine:
- Estimating & Invoicing: Turn a bid into an invoice with one click.
- Mobile Payments: Take credit cards on-site via a phone or tablet.
- ACH & Bank Transfers: Lower fees for large project payments.
- Fast Funding: Get money in 1-2 days or instantly.
- No Long Contracts: Month-to-month flexibility.

If you need to take a credit card payment right at the job site—for a deposit, final payment, or change order—Square is the most popular and reliable choice. Here’s why it’s a favorite among contractors, according to Square’s merchant services and user reviews:
- Free mobile card reader: Square provides a free reader that plugs into your phone’s headphone jack or uses Bluetooth.

Fee Breakdown & Cost Comparison for a Typical Contractor
Let’s compare what you’d pay for a $5,000 project invoice paid via different methods. (Assumes one invoice payment.)
| Payment Method | Fee Calculation | Total Fee | You Receive |
|---|---|---|---|
| Square / Stripe (card online) | 2.9% + 30¢ | $145.30 | $4,854.70 |
| Square (in-person card) | 2.6% + 10¢ | $130.10 | $4,869.90 |
| Stripe ACH | 0.8% (max $5) | $5.00 | $4,995.00 |
| Square ACH (via invoice) | 1% (min $1) | $50.00 | $4,950.00 |
| PayPal online | 3.49% + 49¢ | $174.99 | $4,825.01 |
For large invoices, ACH is dramatically cheaper than credit cards. Encourage clients to pay via ACH or eCheck by offering a small discount—you’ll save hundreds on big projects.
Must-Have Features in Contractor Payment Software
Based on expert advice from U.S. Chamber of Commerce and contractor forums, here’s what to look for:
✅ 1. Mobile Accessibility
You need to invoice and get paid from the job site. Look for apps that work on your phone.
✅ 2. Integrated Invoicing & Estimates
Don’t juggle separate tools. A platform that turns an estimate into a paid invoice saves time and reduces errors.
✅ 3. Multiple Payment Options
Offer credit card, ACH, and even financing (like One Click’s integration with Greensky). Some clients prefer to finance large projects.
✅ 4. Fast or Instant Funding
Cash flow is king. Next-day or instant transfer options (even for a fee) can be worth it to cover material costs.
✅ 5. Fee Markup / Pass-through
Some platforms (like Joist) let you add a line item to cover processing fees, so you effectively pay $0. Ensure it’s compliant with card network rules.
✅ 6. Security & PCI Compliance
Processors like Square and Stripe are PCI-compliant by default, meaning you don’t have to worry about annual compliance paperwork.
