Free Invoice Maker for Houston Businesses

This tool lets you build a professional invoice from scratch, line by line, and export it as a PDF — no account required.
Texas tax considerations for Houston businesses
Like all Texas businesses, Houston companies benefit from the absence of a state income tax. Your invoices will reflect sales tax only where applicable — the combined rate in Houston is 8.25%. The energy sector in particular involves complex tax rules around equipment, services, and offshore work. If your business operates across state lines or handles oilfield services, it is worth confirming your tax obligations with a CPA familiar with Texas energy taxation rather than relying on general guidance.
Invoice practices in Houston's contract economy
Houston's large energy and construction companies typically have formal procurement and accounts payable processes. As a vendor or subcontractor, expect to receive a purchase order before work begins — and to reference that PO number on every invoice you submit. Net 30 to Net 60 payment terms are common with larger operators. For smaller clients and direct service work, Net 15 or due-on-receipt is more typical. Always confirm payment terms in writing before starting work.
Frequently asked questions
What sales tax rate should Houston businesses show on invoices?
The combined sales tax rate in Houston is 8.25% — 6.25% state plus 2% city. This applies to taxable goods and certain services. Texas does not tax most professional services, but construction materials, equipment rentals, and some technology services are taxable. Always confirm your product or service classification with the Texas Comptroller before adding a tax line to your invoices.
Does Texas have a franchise tax that affects my invoicing?
Texas imposes a franchise tax on most businesses with annual revenue above $2.47 million (as of 2024). It is paid to the state annually, not shown on your invoices to clients. Your invoices to clients should reflect sales tax only where applicable. The franchise tax is a separate business obligation you handle through your annual tax return.
How should Houston energy sector contractors invoice clients?
Energy contractors often work against purchase orders issued by large operators. Your invoice should reference the PO number, cost code, and approved scope. Many operators require invoices submitted through their vendor portal rather than by email. Confirm the submission method and invoice format before you begin work to avoid payment delays.
