Terms of Service · NexiNext

These terms are the agreement between you and NexiNext. By creating an account or using the Service, you accept them. If you are accepting on behalf of a company, you confirm you have authority to bind it, and “you” means that company.

1. Who we are, and what the Service is

The Service is operated by NexiNext LLC, a Texas limited liability company, at 26119 Interstate 45 N, Suite 305, Spring, TX 77380, United States. “The Service” means the website at www.nexinext.com, the application at app.nexinext.com, and the NexiNext mobile apps.

NexiNext is a business platform for managing customers, projects, time, quotes, contracts, invoicing, expenses and related work.

2. Eligibility and accounts

You must be at least 18 and able to enter a binding contract. You must give accurate registration details and keep them current.

You are responsible for everything that happens under your account, and for keeping your credentials secure. Turn on two-factor authentication. Tell us at once at hello@nexinext.com if you believe your account has been compromised.

3. Workspaces, roles, and your users

A company workspace has an owner, and members with roles that determine what they can see and do. The company that owns a workspace is responsible for:

Who it invites, what role it gives them, and removing access when someone leaves
Everything those members do in the workspace
Making sure it has the right to enter the customer data it puts into the Service, and that it has given its own customers whatever privacy notice the law requires

The workspace owner can see, export, modify and delete the workspace’s data, including content created by its members. If you use a workspace that belongs to your employer, your employer administers it — not us.

4. Plans, billing and taxes

Plans and trials. Paid plans are billed in advance on the cycle you select. Free trials convert to a paid plan at the end of the trial unless you cancel before it ends.

Payment. Payments are processed by Stripe. By providing a payment method you authorise recurring charges for your plan until you cancel. Card details go to Stripe, not to us — see the Privacy Policy.

Price changes. We may change prices. Changes take effect at your next renewal, and we will give you at least 30 days’ notice by email.

Taxes. Fees are exclusive of taxes. You are responsible for any VAT, IVA, sales or withholding tax that applies, other than tax on our net income.

Failed payment. If a charge fails we will retry and notify you. If it stays unpaid, we may suspend the account. Suspension does not delete your data — see section 12.

Cancellation and refunds. You may cancel at any time; the cancellation takes effect at the end of the current billing period, and you keep access until then. Fees already paid are not refundable, except where required by law or where we have materially failed to provide the Service.

5. Your data, and what you own

You own your data. Everything you and your workspace put into the Service — customer records, documents, files, messages, invoices — remains yours. We claim no ownership of it.

You grant us the limited licence we need to actually run the Service: to host, store, back up, transmit, display and process your data, and to make the derived copies that operating a system requires (search indexes, thumbnails, PDF renderings, backups). That licence exists only to provide the Service to you and ends when your data is deleted.

We do not use your data to train AI models, and neither does our AI provider under our agreement with them.

You are responsible for the lawfulness of the data you put in — including having a lawful basis to hold your own customers’ personal information. If you are subject to a privacy law that requires a data processing agreement, contact us at hello@nexinext.com.

6. Acceptable use

Do not use the Service to:

Break the law, or infringe anyone’s rights
Send spam, or messages the recipient has not agreed to receive
Upload malware, or anything designed to damage or interfere with a system
Try to gain unauthorised access to the Service, another workspace, or anyone’s account
Probe, scan or load-test the Service without our written permission
Scrape it, or use automated means to extract data beyond the documented API
Resell or white-label the Service without a written agreement with us
Issue fraudulent tax documents, or use the invoicing features to misrepresent a transaction
Store data you are not legally allowed to store

We may investigate suspected violations and suspend accounts involved in them.

7. Third-party integrations

The Service connects to Stripe, Facturapi, Gmail, Instagram, and other providers. Your use of each is also governed by that provider’s own terms, and your relationship with them is your own. We are not responsible for their availability, their acts or omissions, or for changes they make to their APIs — any of which can interrupt an integration without our involvement. Optional integrations are off until you connect them.

AI assistants people connect. On the plans that include it, and only where your owners or administrators turn it on, people in your workspace may connect an AI assistant of their own choosing — Claude, ChatGPT or another — to their own NexiNext access. That assistant and its provider are a third-party service the person chooses and uses under their own agreement with that provider: we do not choose it, contract with it or control it. What the assistant reads is sent to its provider at that person’s request; the Privacy Policy explains what is sent. Section 8 says what an assistant may and may not do in NexiNext.

The AI tools list. Where your company uses AI work, NexiNext shows a short list of well-known AI tools for each kind of output, labelled as examples, not endorsements. We review it every quarter, and each tool shows the date it was last reviewed and one line on what reaches that tool and under whose account. The list is not a recommendation of any vendor or of its practices or terms. No tool pays to be listed or ranked, nothing in the list is an affiliate, referral or tracked link, and the list carries no links to vendors at all. Ticking the tools your company already pays for sends no data anywhere: it only decides which tool names your tasks and their briefs show. For a tool that cannot connect to NexiNext, a person’s own AI may write a prompt that the person copies into that tool themselves; we send nothing to it. Which tool is recommended for a task is decided by fixed rules from your ticks, never by an AI. Your use of any listed tool is between you and its vendor.

8. AI features

Some features generate text, summaries, and extracted data using a large language model.

Output can be wrong. AI can produce confident, plausible, incorrect results. You are responsible for reviewing anything it produces before you send it, sign it, file it or rely on it. A price a person’s assistant puts on a quote draft is marked as suggested by that person’s assistant, and the quote cannot be sent until a person has confirmed every such price.
It is not professional advice. Nothing an AI feature produces is legal, tax, accounting or financial advice.
When AI runs. Most AI features run only when someone asks for them. A few run without anyone asking at that moment: on the plans that include it, a message that reaches you from outside — through your forms, a connected inbox or Instagram, or logged by your people — is read when it arrives to label it, unless your owners or administrators turn that off; an automation you write can generate a prospect’s summary or draft an outreach sequence; applying a quarterly budget review prepares that quarter’s profitability analysis; and the problem reports sent to us are read when they arrive, to sort them and, for some, to fix the fault. Section 5 governs what happens to the content they process; the Privacy Policy explains each of these, what is transmitted and to whom.
Availability, limits and quotas for AI features may change, including by plan.
What a connected assistant may do. A person’s assistant (section 7) connects in one of two ways. A Read only connection only reads: it looks things up and cannot change anything, and every customer’s connection is of this kind. A Read and suggest connection is for employees only, and only where your owners or administrators have turned on AI assistants can work on tasks: it may also leave drafts on tasks — draft answers to a task’s brief, a draft of ideas and files, and draft replies in the conversation on an idea — that only that person can see. Nothing an assistant leaves is live until its person publishes it in NexiNext. Publishing is that person’s own act, with the same effect and the same responsibility as if they had done each step themselves: it notifies the team and applies the next steps they kept. An assistant can never publish, delete, see what its person can’t, or set off an automation.
Your customers’ information. A task’s brief can include what your customers have told you, such as their answers to the questions you send them, and the notes you keep about them. Where you let your people connect their own AI assistants, those assistants may read it, and it then goes to those assistants’ providers. As the party responsible for your customers’ personal information, you are the one who must tell them, in the privacy notice you give them (section 3), that their information may be read with your people’s AI tools.
Tasks that never leave NexiNext. If you mark a kind of task Never leaves NexiNext, nothing about the brief or the files of those tasks goes to any AI model, whether a person’s own assistant or our AI features. A connected assistant still sees what its person’s ordinary look-ups show of any task: its name and its dates.

9. Electronic invoicing and fiscal documents

Read this section if you use the CFDI features.

The Service prepares and transmits invoices for stamping through an authorised Mexican PAC (Proveedor Autorizado de Certificación). You remain the taxpayer. You are solely responsible for the accuracy, completeness, timeliness and legal correctness of every fiscal document issued from your account — the RFC, the régimen fiscal, the uso de CFDI, the amounts, the tax treatment, the cancellations and the complements.

NexiNext is not a tax adviser, is not an accountant, and is not the PAC. We provide software. We do not verify that a document is fiscally correct, and we are not liable for tax assessments, fines, surcharges, rejected deductions or penalties arising from documents issued through the Service. Consult your accountant.

You are responsible for keeping your digital seal certificate (CSD) valid and its password current. Stamping will fail if the certificate expires or is revoked by the SAT.

Availability of stamping depends on the PAC and on the SAT, neither of which we control.

10. Availability, support and beta features

We aim to keep the Service available and to fix problems promptly, but we do not offer a service level agreement unless we have signed one with you separately. The Service can be interrupted by maintenance, by a provider outage, or by something we did not foresee.

Support is provided by email at hello@nexinext.com during business hours.

Features labelled beta, preview or experimental are provided as-is, may change or be withdrawn, and should not be relied on for anything critical.

We may modify the Service, and may discontinue a feature. If we discontinue something material, we will give you reasonable notice and, where practical, a way to export the affected data.

11. Your data when things end

You may export your data at any time while your account is active, through the export features and the API.

If you cancel, or if we terminate for cause, your data remains available for export for 30 days after the account closes. After that we delete or anonymise it within 90 days, except for records we must keep — see the retention section of the Privacy Policy. Fiscal records in particular are retained for five years because Mexican law requires it.

Do not treat NexiNext as your only copy of anything you cannot afford to lose.

12. Suspension and termination

You may close your account at any time.

We may suspend or terminate your access if you materially breach these terms, if your account is used unlawfully, if payment remains overdue after notice, or if we must do so to comply with the law or to protect the Service or other users. Except where the breach is serious or unlawful, we will give you notice and a reasonable chance to fix it first.

We may also terminate for convenience on 30 days’ notice, in which case we will refund any prepaid fees for the unused part of your term.

13. Intellectual property

The Service, its software, design, brand and content are ours (or our licensors’) and stay that way. These terms grant you a limited, non-exclusive, non-transferable right to use the Service during your subscription. You may not copy, modify, reverse engineer, or create derivative works from the Service, except to the extent the law says you may despite this clause.

If you send us feedback or suggestions, we may use them without obligation to you.

14. Warranty disclaimer

The Service is provided “as is” and “as available”. To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, or that it will meet your requirements.

15. Limitation of liability

To the fullest extent the law allows:

Neither party is liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, revenue, goodwill or data, even if advised such damages were possible.
Our total liability arising out of or relating to these terms or the Service is limited to the fees you paid us in the 12 months before the event giving rise to the claim.

These limits do not apply to fraud, wilful misconduct, or anything the law does not permit us to limit.

16. Indemnity

You will defend and indemnify us against claims, damages and reasonable costs arising from your data, your use of the Service in breach of these terms, or your violation of law or of a third party’s rights.

17. Governing law and disputes

These terms are governed by the laws of the State of Texas, United States, without regard to conflict-of-laws rules. The state and federal courts located in Montgomery County, Texas have exclusive jurisdiction, and both parties consent to that venue.

If you are a consumer in Mexico, nothing in this section deprives you of the protections of Mexican consumer law or of your right to bring a matter before PROFECO or a competent Mexican court.

18. Changes to these terms

We may update these terms. The date at the top changes with them. For material changes we will notify account holders by email at least 30 days before they take effect. If you keep using the Service after that, you accept the updated terms; if you do not accept them, cancel before they take effect.

19. General

Entire agreement. These terms and the Privacy Policy are the whole agreement between us on this subject, and replace anything said earlier.

Assignment. You may not assign these terms without our consent. We may assign them to a successor in a merger or acquisition.

Severability. If a provision is held unenforceable, the rest stays in force.

No waiver. Not enforcing something once does not waive it.

Force majeure. Neither party is liable for a failure caused by something genuinely beyond its reasonable control.

Notices. We will reach you at the email on your account. Reach us at hello@nexinext.com.
