Terms of service

Last updated: October 2026.

Site use

This site is provided as-is. Content is informational; nothing here constitutes a binding offer of services. Engagement terms are agreed separately in a written statement of work.

Intellectual property

The site's text, design, and source code are mine unless noted otherwise. Case studies describe real engagements; client names are anonymized where the work is under NDA. You may link to and quote from case studies with attribution.

Website plans

Draft for review; not legal advice.

• Cancellation. Monthly plans can be cancelled at any time, effective at the end of the current billing month.
• Annual billing. Annual billing is a year paid upfront, at a discounted rate. It is not refunded on cancellation; the plan stays live until the paid year ends and then does not renew.
• Domain. We register your domain while your plan is active. Renewal is included only for standard TLDs (.com, .net, .org); other TLDs are renewed at your cost.
• At exit. You keep your content. You can take your domain with you by paying its registration cost, and we transfer it to your name. The site's source code is handed over after 12 paid months.
• Maintenance. Monthly allowances (change requests or hours, depending on plan) do not carry over, and work beyond them is quoted.

Invoice API plans

• Quota. Each plan includes a monthly quota of electronic documents: one accepted comprobante that reached Hacienda. Retries and submissions against the test environment never count. Dev is sandbox-only: it has a per-day submission limit and no document quota. Self-serve tiers are billed monthly.
• Overage. Submissions continue past the quota; documents beyond it are charged as document overage, per document, at the rate shown on the Invoice API page.
• Issuer and provider. You remain the issuer of record. We operate as a notified system provider and sign and submit on your behalf. We make no claim of Hacienda certification or homologation.
• Document archive. We keep your electronic documents in the document archive for the five-year legal retention period, and we can export them to you and to Hacienda on request, including on exit. We remain the archive of record: a storage bucket you connect (Business) or we provision for you (Enterprise) is an additional copy you control, and does not move that retention duty.
• Enterprise. The service commitment on Enterprise is a separate annual contract, not the monthly plan price.

No warranty

The site is provided without warranty of any kind. I try to keep it accurate and available, but I make no guarantees.

Governing law

Engagements are governed by the laws of the jurisdiction agreed in the statement of work. Disputes are resolved per the dispute resolution clause in the SOW.
