1. Delaware-specific invoice requirements
- Sales tax line: 0.00% state rate. Most services rendered in Delaware are exempt from sales tax — but materials, parts, and tangible goods are not. No state or local sales tax. Gross receipts tax on businesses instead.
- Late-fee cap: Delaware statute Del. Code tit. 6, §2301 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 Delaware get 72-hour cancellation rights on certain home-services contracts. Disclose this in your terms.
2. Electrician line items + standard terms
Every electrician invoice in Delaware should itemize work clearly. Standard electricians use Net 14 terms with a 30% deposit required upfront.
- Service call fee — billed by flat (~$100 default).
- Labor — billed by hour (~$125 default).
- Materials — billed by itemized.
- Permit fee — billed by passthrough.
3. Electrician licensing in Delaware
Licensed at state level. Journeyman + master tiers. Bonding often required for jobs over a state-set threshold.
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. Delaware customers expect digital payment options today — accepting card and ACH typically reduces days-to-paid by 30–50%.
