Terms & Conditions

Plain English. How proposals, projects, invoices, and payments work with Nio Tech.

Last updated: September 19, 2026

These Terms & Conditions of Service ("Terms" or "Agreement") govern all products, services, and work performed by Nio Tech Corp ("Company," "Nio Tech," "we," "our," or "us"), a licensed low-voltage contractor operating in the State of New York, for the client identified on the associated proposal, invoice, or work order ("Client," "you," or "your"). They also govern your use of nio-tech.net and our online invoice payment page. By signing a proposal, approving a quote, issuing payment (including online through our payment page), or permitting work to commence, you agree to be bound by these Terms in their entirety.

The short version

Proposals are valid for 30 days. Unless a proposal says "fixed price," pricing is an estimate, and we will tell you before proceeding if costs change materially.
A 50% deposit is due before work starts or materials are ordered, and it is non-refundable. Projects over $10,000 may be billed in milestones instead.
The final balance is due within 7 days of substantial completion or the final invoice, whichever comes first.
Pay online by card or bank transfer through Stripe, or by check, ACH or wire, or Zelle. Credit card payments may carry a processing surcharge of up to 3.5%, shown before you pay.
Late balances accrue 1.5% per month starting on the 8th day after the due date.
Changes need a signed change order before the extra work is done.
One-year workmanship warranty. Equipment carries the manufacturer's warranty.
Security systems are deterrents and documentation tools. They do not guarantee that a theft, break-in, or other loss will not happen.

1. Scope of services

Nio Tech Corp provides professional installation, configuration, maintenance, and consulting services for low-voltage systems including, but not limited to:

Security camera systems (IP, CCTV, NVR/DVR, cloud-based surveillance, remote monitoring)
Access control and intercom systems (keycard, fob, biometric, video intercom, DoorKing, Paxton, HID)
Smart home automation (lighting, shades, climate control, entertainment, Control4, Lutron)
WiFi and networking infrastructure (UniFi, enterprise wireless, structured cabling, routing)
Audio and phone systems (distributed audio, commercial sound, VoIP, Sonos, Russound, LEA, JBL)
Low-voltage wiring and signage (Cat6/fiber, AV wiring, digital signage for commercial and residential properties)

The specific scope, pricing, and deliverables for each project are detailed in the associated written proposal or work order ("Proposal"), which is incorporated into these Terms by reference.

2. Proposals and estimates

2.1 Validity

All proposals and estimates are valid for thirty (30) calendar days from the date of issuance unless otherwise stated in writing. After expiration, pricing and availability are subject to change without notice.

2.2 Acceptance

A Proposal is deemed accepted upon your written approval (including email or electronic signature), payment of the required deposit, or verbal authorization to proceed with work. You agree that electronic signatures and electronic records are valid and enforceable. If you accept on behalf of a company, building, board, or another person, you confirm that you have authority to do so.

2.3 Estimates vs. fixed pricing

Unless the Proposal expressly states "fixed price," all pricing is provided as an estimate. Actual costs may vary based on site conditions, concealed obstacles, code requirements, or scope changes. We will notify you of any material variance before proceeding.

3. Payment terms

3.1 Deposit

A non-refundable deposit of fifty percent (50%) of the total project cost is required before any work commences or materials are ordered. For projects exceeding $10,000, we may structure a milestone-based payment schedule as outlined in the Proposal.

3.2 Progress payments

For larger installations, interim payments may be required at specified milestones (for example, rough-in completion, equipment delivery, or system commissioning). These milestones will be identified in the Proposal.

3.3 Final payment

The remaining balance is due upon substantial completion of the work, defined as the point at which the system is installed, tested, and operational. Final payment is due within seven (7) calendar days of project completion or delivery of the final invoice, whichever comes first.

3.4 Accepted payment methods

We accept payment by check, ACH or wire transfer, credit card, Zelle, or other methods specified on the invoice. Card and ACH payments can be made online through our secure payment page (see Section 4). Credit card payments may be subject to a processing surcharge of up to 3.5% where permitted by law. Any surcharge will be disclosed on your invoice or at checkout before you pay, and the amount shown at checkout is the total you will be charged.

3.5 Late payments

Invoices not paid within the specified terms accrue a late fee of 1.5% per month (18% per annum) on the outstanding balance, beginning on the eighth (8th) day after the due date. We reserve the right to suspend all work, withhold equipment, or revoke system access until the account is brought current.

3.6 Collections

If an account remains unpaid for more than sixty (60) days, we may refer the balance to a collections agency or pursue legal action. You are responsible for all costs of collection, including reasonable attorney's fees, court costs, and collection agency fees.

4. Online payments through Stripe

Our online payment page at nio-tech.net/pay lets you look up an invoice by invoice number and the email address on file, review the amount due, and pay through a checkout page hosted by Stripe, Inc. ("Stripe"). By using it you agree to the following:

Verification. You may only pay invoices that were issued to you or that you are authorized to pay. We verify the invoice number against the email address on the invoice. Do not attempt to look up invoices that are not yours.
Amount. The amount shown at checkout is the current open balance on the invoice, including any prior partial payments, plus any processing surcharge disclosed there. When you complete checkout, you authorize Nio Tech, through Stripe, to charge that amount to the payment method you provide.
Card payments. Card details are entered on Stripe's hosted page and never reach our servers. Card payments are subject to your card issuer's terms.
ACH bank payments. When you pay by bank account you authorize a one-time electronic debit from that account for the invoice amount. ACH payments can take several business days to settle. The invoice is not considered paid until the funds settle. A debit that is returned or reversed reinstates the balance, and Section 3.5 applies from the original due date.
Returned payments. If a check, ACH debit, or card payment is returned, reversed, or declined, you are responsible for any bank or processor fees we incur, and the original balance remains due.
Stripe's terms. Stripe is an independent payment processor. Your use of the checkout page is also subject to Stripe's own terms and privacy policy, available on stripe.com. We are not responsible for outages, errors, or decisions by Stripe or your bank.
Receipts and records. Stripe emails a receipt to the address used at checkout. Our success page confirms the payment was received, and the matching QuickBooks invoice is updated automatically, usually within minutes. The QuickBooks record is the authoritative statement of your account.
Agreement to these Terms. Where the checkout page asks you to accept these Terms, ticking the box is your agreement. Completing a payment is also your agreement to these Terms, whether or not a checkbox is displayed.
Security. Do not share invoice numbers or payment links publicly. If you believe someone has paid or attempted to pay an invoice without authorization, contact us immediately at support@nio-tech.net.

5. Refunds, payment disputes, and chargebacks

Deposits are non-refundable (Sections 3.1 and 6.1).
Labor and services already performed are non-refundable.
Materials. Custom, special-order, and non-stock equipment is non-refundable and non-returnable. Stock items that a supplier will take back may be credited less the supplier's restocking fee (typically 15% to 25%) and any shipping costs.
Overpayments and duplicate payments are refunded in full to the original payment method within ten (10) business days of our confirming them.
Invoice questions. If you believe an invoice is wrong, tell us in writing before the due date and we will review it and correct genuine errors. Undisputed portions remain due on time.
Talk to us before disputing a charge. Email support@nio-tech.net and we will resolve most issues quickly. If you file a chargeback or ACH dispute on a valid invoice without contacting us first, the amount remains due, you are responsible for any dispute fees we are charged, and the account is treated as past due under Sections 3.5 and 3.6.
Approved refunds are issued to the original payment method. Stripe or your bank may take several business days to post them.

6. Cancellation and termination

6.1 Cancellation by Client

You may cancel the project at any time by providing written notice to us. Upon cancellation, the following applies:

Pre-installation cancellation. If cancellation occurs before work has commenced and no materials have been ordered, the deposit is forfeited as liquidated damages to cover administrative costs, scheduling, and lost opportunity.
Cancellation after work begins. You shall pay for all work performed to date, all materials ordered or received (whether installed or not), any restocking fees assessed by suppliers (typically 15% to 25%), and a cancellation fee equal to 20% of the remaining unperformed contract value.
Custom or special-order equipment. Materials ordered specifically for your project (including custom-configured hardware, specialty finishes, or non-stock items) are non-refundable and non-returnable.

6.2 Cancellation by Company

We reserve the right to cancel or suspend work at any time if: (a) you fail to make payments when due; (b) site conditions are unsafe or not as represented; (c) you materially breach these Terms; or (d) circumstances beyond our reasonable control prevent performance. In such cases, you shall pay for all work completed and materials procured through the date of cancellation.

6.3 Rescheduling

Rescheduling requests made within 48 hours of a confirmed installation date may be subject to a rescheduling fee of up to $250 to cover crew scheduling and logistics costs.

6.4 Residential clients

If you are a homeowner and the work is home improvement under New York General Business Law Article 36-A, you may have additional rights, including a right to cancel within three business days of signing a contract at your home. Nothing in these Terms reduces those rights. Where these Terms conflict with that law, the law controls and these Terms are read to comply with it.

7. Change orders

Any changes to the original scope of work must be documented in a written Change Order signed by both parties before additional work is performed. Change Orders may affect the project price, timeline, or both. We are not obligated to perform work outside the original Proposal without a signed Change Order. Verbal requests for additional work will be documented by us and presented as a Change Order for your approval.

8. Project timeline and delays

8.1 Estimated timelines

Project timelines provided in Proposals are estimates based on normal conditions. We will make commercially reasonable efforts to complete work within the estimated timeframe but do not guarantee specific completion dates unless explicitly stated in writing.

8.2 Delays beyond our control

We are not liable for delays caused by: supply chain disruptions, material shortages, shipping delays, permitting or inspection delays, Client-caused delays (including failure to provide site access, decisions, or approvals), work performed by other trades, weather, or acts of God.

8.3 Client-caused delays

If the project is delayed due to your action or inaction for more than fourteen (14) calendar days, we may invoice for work and materials completed to date and charge a daily storage fee for equipment held on your behalf.

9. Warranty

9.1 Workmanship warranty

We warrant all installation labor and workmanship for a period of one (1) year from the date of project completion. This warranty covers defects in installation technique, wiring, mounting, and configuration performed by our technicians.

9.2 Equipment warranty

All hardware, equipment, and devices are covered by the manufacturer's warranty, which varies by product and brand. We will assist you in processing manufacturer warranty claims during the warranty period. We do not independently warrant third-party hardware.

9.3 Warranty exclusions

Warranties do not cover: damage caused by misuse, abuse, negligence, power surges, lightning, water damage, or unauthorized modifications; normal wear and tear; consumable components (batteries, bulbs, fuses); software bugs or third-party service outages; and issues arising from your failure to maintain systems as recommended.

9.4 Service after warranty

After the warranty period, maintenance and repair services are available under a separate Service Agreement or on a time-and-materials basis at our then-current rates.

These are the only warranties we give. To the extent permitted by law, we disclaim all other warranties, express or implied, including merchantability and fitness for a particular purpose.

10. Limitation of liability

10.1 Maximum liability

To the fullest extent permitted by law, our total aggregate liability arising out of or related to any project shall not exceed the total amount paid by you to us for the specific project giving rise to the claim.

10.2 Exclusion of consequential damages

In no event shall we be liable for any indirect, incidental, special, consequential, or punitive damages, including but not limited to: loss of profits, loss of data, business interruption, property theft, security breaches, or any damages arising from the failure or malfunction of installed systems, regardless of whether we were advised of the possibility of such damages.

10.3 Security system disclaimer

We install security and surveillance systems as a deterrent and documentation tool. We do not guarantee the prevention of theft, vandalism, unauthorized entry, or any criminal activity. We are not an alarm monitoring company and do not provide 24/7 monitoring services unless separately contracted. You acknowledge that no security system can guarantee absolute protection. We are not an insurer; the prices we charge are for equipment and installation and are not related to the value of your property or the losses you could suffer, and you should maintain your own property, liability, and business insurance.

10.4 Network and connectivity disclaimer

For systems relying on internet connectivity, we are not responsible for failures caused by your internet service provider, network outages, bandwidth limitations, or third-party cloud service disruptions.

Some jurisdictions do not allow certain limitations, so some of the above may not apply to you. Nothing in these Terms limits liability for death or personal injury caused by our negligence, for fraud, or for anything else that cannot be limited by law.

11. Client responsibilities

You agree to:

Provide safe, timely, and unobstructed access to the work site during agreed-upon hours.
Ensure the site is clean, clear, and ready for installation (for example, furniture moved, walls accessible, power available).
Provide accurate information about existing systems, building infrastructure, and any known hazards.
Obtain any necessary approvals from building management, HOA, landlords, or co-op boards prior to scheduled installation.
Make timely decisions regarding equipment selection, placement, and configuration to avoid project delays.
Maintain adequate internet bandwidth and electrical infrastructure to support installed systems.
Designate an authorized point of contact who can make binding decisions on your behalf during the project.
Use the installed systems lawfully, including compliance with any rules on camera placement, audio recording, signage, and notice to tenants, employees, or visitors that apply to your property.

12. Permits, codes, and inspections

We will perform all work in compliance with applicable local, state, and federal codes and regulations. If permits are required, we will advise you and may assist in obtaining them. Permit fees are your responsibility unless included in the Proposal. Any additional work required to meet code compliance discovered during installation may result in a Change Order.

13. Property and site conditions

13.1 Existing conditions

Installation of low-voltage systems may require drilling, cutting, patching, and routing of cables through walls, ceilings, and floors. We will exercise reasonable care to minimize cosmetic impact, but you acknowledge that some minor patching or touch-up may be necessary and is your responsibility unless painting or patching services are included in the Proposal.

13.2 Concealed conditions

We are not responsible for pre-existing concealed conditions including but not limited to: asbestos, lead paint, mold, faulty wiring, structural deficiencies, or code violations. Discovery of such conditions may require a Change Order or project suspension.

13.3 Third-party damage

We are not liable for damage caused by other contractors, tradespeople, or building personnel to equipment or wiring installed by us.

14. Intellectual property and system access

All system designs, network configurations, programming, and custom integration work created by us remain the intellectual property of Nio Tech Corp. Upon full payment, you receive a non-exclusive license to use these configurations for the installed systems. System login credentials and access information will be provided to you upon final payment. We may retain administrative access for warranty and support purposes unless you request removal in writing.

Content on nio-tech.net, including text, images, and design, belongs to Nio Tech or its licensors and may not be reused without permission. Manufacturer names and logos belong to their respective owners and are used only to describe products we install.

15. Confidentiality

We treat all Client information, including property layouts, security system configurations, access codes, and network credentials, as confidential. We will not disclose such information to third parties except as required to perform the contracted work or as required by law. How we handle personal information, including what you enter on the payment page, is described in our Privacy Policy.

16. Indemnification

You agree to indemnify, defend, and hold harmless Nio Tech Corp, its owners, officers, employees, and subcontractors from and against any and all claims, liabilities, damages, losses, and expenses (including reasonable attorney's fees) arising from: (a) your misuse of installed systems; (b) your failure to comply with these Terms; (c) your breach of applicable laws; or (d) claims by third parties related to your use of the systems or services provided.

17. Force majeure

Neither party shall be liable for failure or delay in performance caused by circumstances beyond their reasonable control, including but not limited to: natural disasters, pandemics, government actions, labor disputes, supply chain disruptions, cyberattacks, utility failures, or acts of terrorism. The affected party shall notify the other party promptly and make reasonable efforts to mitigate the impact. Payment obligations for work already performed and materials already procured are not excused.

18. Dispute resolution

18.1 Good faith negotiation

The parties agree to attempt to resolve any dispute arising under this Agreement through good faith negotiation for a period of thirty (30) days from the date written notice of the dispute is given. Start by emailing support@nio-tech.net.

18.2 Mediation

If negotiation fails, the parties agree to submit the dispute to non-binding mediation administered in New York County, New York, before resorting to litigation.

18.3 Governing law and jurisdiction

This Agreement is governed by and construed in accordance with the laws of the State of New York, without regard to conflicts of law principles. Any legal action shall be brought exclusively in the courts of New York County, New York.

19. General provisions

Entire agreement. This Agreement, together with the associated Proposal and any Change Orders, constitutes the entire agreement between the parties and supersedes all prior negotiations, representations, or agreements. If documents conflict, a signed Proposal or separately negotiated written agreement controls, then Change Orders, then these Terms. Terms printed on your purchase order or vendor forms do not apply unless we sign them.
Amendments. No modification of this Agreement, as it applies to a signed Proposal, is valid unless made in writing and signed by both parties.
Severability. If any provision of this Agreement is held invalid or unenforceable, the remaining provisions continue in full force and effect.
Waiver. Failure by either party to enforce any provision does not constitute a waiver of the right to enforce that provision in the future.
Assignment. You may not assign this Agreement without our prior written consent. We may assign or subcontract portions of the work as needed.
Notices. All notices under this Agreement shall be in writing and sent to the addresses specified in the Proposal, or to such other address as a party may designate in writing. Notices to us may be sent to support@nio-tech.net or to the mailing address in Section 23.
Survival. Sections regarding Payment, Limitation of Liability, Indemnification, Confidentiality, and Dispute Resolution survive termination of this Agreement.
