If you’re building business credit from a brand-new LLC, net-30 vendor accounts are the most reliable first tradelines you can open. A net-30 account lets you buy supplies on credit and pay within 30 days — and when the vendor reports your on-time payments to the business credit bureaus, each account becomes a positive tradeline on your business credit file.
Business credit bureaus — Dun & Bradstreet, Experian Business, and Equifax Business — build your file from the tradelines that report to them. Vendor accounts that report are the foundation of that file. Without them, your business has no credit history, and every lender falls back on your personal credit.
Not all net-30 vendors are worth your time. The ones that actually build credit share a few traits:
Start with two to three verified accounts. You don’t need a dozen vendors on day one. A small set of accounts that report consistently, paid on time, builds a stronger file than a pile of unused accounts. You can add more as your profile matures.
Be realistic about the investment. Activating vendor reporting typically costs around $250 — that’s minimum purchases across a few vendors, buying real supplies your business needs, not paying fees. It’s not free, and anyone who says otherwise is overselling.
The hard part is knowing which vendors actually report to which bureaus, their minimum orders, and their approval requirements. The Business Credit DIY Playbook includes 13 verified net-30 accounts with bureau reporting confirmed, organized by tier, plus the exact 90-day application sequence — for a one-time $79.
