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. IT Consultant line items + standard terms
Every it consultant invoice in Delaware should itemize work clearly. Standard it consultants use Net 30 terms with no deposit required.
- Block-of-hours retainer — billed by flat.
- Onsite labor — billed by hour (~$175 default).
- Remote labor — billed by hour (~$145 default).
- After-hours surcharge — billed by pct.
- Hardware — billed by itemized.
3. IT Consultant licensing in Delaware
No general license. Vendor certifications (Microsoft, Cisco, AWS) drive credibility. SOC 2 expected for handling client data.
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%.
