5 Simple Steps to Track Subcontractor Expenses the Right Way
Article • April 30th, 2026 • Amber MalonePaying subcontractors is common. Tracking them correctly is where many businesses get into trouble. This companion guide walks you through five simple steps to organize payments, collect W-9s, prepare for 1099s, and avoid year-end stress using QuickBooks Online.
If you use subcontractors in your business, tracking their payments correctly is not optional.
It affects:
• Your 1099 filings
• Your tax reporting
• And how stressful January feels every year.
The good news is this does not need to be complicated.
Here is the exact process I recommend.
1. Collect a W9 Before You Pay
This is the most important step.
Always collect a W-9 before issuing the first payment.
If you wait:
• People stop responding
• You lose leverage
• You are chasing documents at tax time.
Inside QuickBooks Online, you can:
• Request W9 information directly.
• Store the completed form in the vendor profile.
Do this once, and you avoid problems later.
2. Set Up Vendor Profiles the Right Way
Every subcontractor should have a complete vendor profile.
Make sure it includes:
• Legal name.
• Address.
• Email.
• W9 attached.
• Marked as a contractor.
QuickBooks can automatically send 1099s, but only if this information is correct.
3. Keep Subcontractor Payments Organized
Do not scatter these payments across multiple categories.
Keep it simple and consistent.
Use clear categories like:
• Subcontractor expenses.
• Contract labor.
• Cost of goods sold labor.
This makes your reports easier to review and decreases errors when preparing 1099s.
4. Separate Reimbursements from Actual Pay
Not everything you pay a subcontractor is income to them.
If they purchase items on your behalf, that is a reimbursement.
Examples include:
• Materials.
• Supplies.
• Filing fees.
If you do not separate this:
• They may overpay taxes.
• Your records become inaccurate.
Simple fix:
Use bills in QuickBooks and split line items between:
• Services.
• Reimbursements.
5. Review Your Reports Before Year-End
Do not wait until January to clean things up.
Instead, review your numbers in the fourth quarter.
Look at:
• Your Profit and Loss.
• Vendor totals.
• Any missing information.
This gives you time to fix issues before deadlines hit.
Final Thought
Tracking subcontractor expenses is not about doing more work. It is about doing the right work at the right time.
When you follow these five steps consistently:
• 1099s become simple.
• Your records stay clean.
• Tax season becomes much easier to manage.
