1. New Mexico-specific invoice requirements
- Sales tax line: 4.88% state rate. Services billed to NM customers must include sales tax. GRT (gross receipts tax) 4.875% applies broadly including services.
- Late-fee cap: New Mexico statute N.M. Stat. §56-8-3 caps interest on unpaid invoices at 1.5% per month. Spell out the rate in writing on every invoice and in your contract — courts won't enforce undisclosed fees.
- Right-to-cancel notice: Customers in New Mexico get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Insulation Contractor line items + standard terms
Every insulation contractor invoice in New Mexico should itemize work clearly. Standard insulation contractors use Net 14 terms with a 30% deposit required upfront.
- Material — per sqft — billed by sqft.
- Labor — billed by hour (~$70 default).
- Removal of old insulation — billed by flat.
3. Insulation Contractor licensing in New Mexico
EPA certifications required for older homes. State licensing varies.
4. Send and follow up
Send the invoice the same day work completes. Use software that records open events and offers a one-click online payment so you don't need to chase a check by mail. New Mexico customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
