Net-30 Contractor Accounts: How They Work

Net-30 keeps your crew working before AP cuts a check — but only if the account is set up clean. Here's what net-30 means, how to qualify, and how billing rolls up.

What net-30 means

Net-30 means the balance is due 30 days from the invoice date. You get the service now — the dumpster drops, the fuel fills, the restrooms get placed — and pay on terms, which lets a contractor keep sites moving without every order waiting on a check. It's the standard way established contractors buy site services.

How to qualify

New accounts typically start with a quick credit review and a signed services (or fuel-supply) agreement. Depending on the account, a first order may run on prepaid or first-order terms and then move to net-30 as the account establishes a history. Your rep confirms the terms at setup — no guessing. Larger or multi-site accounts can set a credit line sized to expected volume.

COI, W-9, and vendor prequal

Contractor accounts usually need paperwork on both sides, and we keep ours ready:

  • Certificate of insurance (COI) emailed to your office on request, so your compliance file is complete before the first drop.
  • W-9 on request.
  • Vendor prequal — we're set up to move quickly through builder and owner vendor portals; give us the portal and we start the application.

How PO and billing work

  • One PO per project if you work that way — or per-order, whichever your AP prefers.
  • Consolidated invoicing — every service (restrooms, dumpsters, fence, diesel) across every site can roll onto one monthly statement, itemized by site, service, and (for fuel) equipment tag. Your bookkeeper reconciles one document, not four.
  • Photo proof and metered tickets on file — clean backup for any billing question, owner request, or inspection.
  • Flat, all-in quotes — the number your rep quotes is the number you pay; no fuel or environmental surcharge tacked on later.

Why it's cleaner on one account

Running fuel, toilets, dumpsters, and fence through four vendors means four credit applications, four COIs to chase, four invoices, and four reconciliations a month. Consolidating onto one SolidSite account means one set of terms, one statement, and one dispatcher who can move any of it — which is the whole point of the one-ticket model.

Late terms, straight

Past-due balances accrue interest per the terms on your invoice (stated up front, per Texas Finance Code). We'd rather keep the account clean and the crew supplied than chase paper — so if something's off on a statement, one call to your rep sorts it.

Straight answers

Questions, answered

Common questions on net-30 accounts — straight from dispatch.

What does net-30 mean?
The invoice is due 30 days from its date. You get the service now and pay on terms.
How do I qualify for net-30?
A quick credit review and a signed agreement. New accounts may start on first-order terms and move to net-30 as history builds. Your rep confirms.
Can I get one invoice for all my sites?
Yes — every service and site can roll onto one monthly statement, itemized by site, service, and equipment tag for fuel.
Do you provide a COI and W-9?
Yes — COI emailed on request and a W-9 on request. We move fast through vendor-prequal portals.
Are there hidden surcharges on the invoice?
No. Quotes are flat and all-in — no fuel or environmental add-ons after the fact.
