HIC registration number, insurance carrier, bond details — entered once, displayed on every estimate and PDF. Signature audit trail (timestamp, name, IP) on every customer acceptance. Built by an active New Jersey HIC running a real painting business in Atlantic County.
A short reference for what NJ's Contractors' Registration Act (N.J.S.A. 56:8-136 et seq.) asks of home improvement contractors. Not legal advice — verify the current rules with your attorney or the NJ Division of Consumer Affairs.
Anyone offering home improvement work in NJ must register with the Division of Consumer Affairs and receive a HIC registration number. The number must appear on contracts, invoices, business cards, vehicles, and advertising.
Home improvement work totaling more than $500 must be performed under a written contract that includes scope of work, total price, start and end dates, and contractor identification (including the HIC number).
Registered HICs must carry commercial general liability insurance of at least $500,000. Proof of insurance is part of the registration renewal process.
For door-to-door and other off-premises home improvement sales, NJ buyers have the right to cancel the contract within three business days of signing. The contract must disclose this right.
Contractors may not advertise services without the HIC number, misrepresent their registration status, or engage in unconscionable practices. Violations can result in DCA enforcement action.
Most contractor software treats HIC numbers, bond details, and insurance carriers as notes-field afterthoughts. Senku surfaces them as proper settings, displayed on every customer-facing estimate and PDF.
Enter your NJ HIC registration number and state once in Settings. It appears in the header of every estimate, every PDF export, and the customer-facing portal — automatically, never by retyping.
Insurance carrier, policy number, expiration date, and certificate URL. Bond company and bond amount. All optional, all toggleable, all shown to the customer alongside the estimate when enabled.
When a customer signs an estimate on their portal link, Senku records the timestamp, the typed name, and the IP address. Stored against the estimate. Useful if you ever need to show that a customer agreed to a specific scope and price.
Every estimate exports to a PDF with your branding, your compliance disclosures, the line items, terms, and signature blocks. Use it as the written contract for jobs over $500, or attach it to your existing contract template.
When the scope grows mid-job, request a change order through the portal. Customer reviews and accepts on their phone. Signed acceptance is captured alongside the original estimate — no separate paperwork to chase.
Every payment recorded with method, date, amount, and notes. Stripe, Venmo, Zelle, cash, check. Refunds tracked separately. If a customer disputes a payment six months later, the record is there.
The New Jersey Contractors' Registration Act (N.J.S.A. 56:8-136 et seq.) requires anyone offering home improvement services in NJ to register with the Division of Consumer Affairs and display their HIC registration number on contracts, invoices, business cards, and advertising. Home improvement work over $500 must be performed under a written contract. Contractors must also carry commercial general liability insurance of at least $500,000.
Senku surfaces the fields that NJ HIC contracts need — your registration number, insurance carrier and policy number, bond company and amount, customer name and address, project scope, line-item totals, payment terms, and a signature with timestamp + IP audit trail — and exports a PDF you can use as the written contract. The legal-compliance review of any specific contract template is on you or your attorney; Senku provides the structure and the audit trail.
You enter it once in Settings (HIC number, state, and an enable toggle). It then appears on every estimate, PDF export, and customer-portal view automatically. Same pattern for your insurance carrier / policy / expiration and your bond company / amount. No retyping per estimate; no risk of forgetting it on a job.
When a customer signs an estimate on their customer-portal link, Senku records the acceptance timestamp, the typed name, and the IP address that submitted the signature. This information is stored against the estimate and is available on the contractor-side portal. Useful if you ever need to demonstrate that a customer agreed to a specific scope and price at a specific time.
Yes. The HIC / insurance / bond fields are generic — set your state and number once and they're displayed on every estimate regardless of where the job is. NJ is where the founder runs his own contracting business, so the product is opinionated about NJ requirements, but nothing about Senku is NJ-only.
Senku is built by SJ Tech Solutions. The founder operates Perfect Finish Painters LLC in Atlantic County, NJ — an active NJ HIC — and built Senku because the alternatives didn't fit the way a working contractor actually runs a business.
