Engagement Terms

Last updated August 9, 2026

These terms summarise how Arthus Systems LLC sells and delivers its services. They sit alongside the written agreement signed for each project, which takes precedence where the two differ.

What we sell

Arthus Systems LLC provides custom software development, SaaS product development, AI automation, web and mobile application development, UI/UX design, and technical systems work. All of it is delivered as professional services under a written agreement, scoped and quoted for each client.

What we do not provide

We do not provide financial, investment, tax, or legal services. We do not sell, trade, or hold cryptocurrency or other digital assets. We do not operate a marketplace, and we do not process or hold payments on behalf of third parties.

How an engagement starts

Every project is quoted individually. After a scoping discussion we issue a written proposal setting out the scope, milestones, timeline, and price. Work begins once you approve that proposal in writing and the initial deposit is received.

Pricing and currency

All prices are quoted, invoiced, and settled in United States Dollars (USD). We do not publish fixed price lists, because scope determines cost. Every client receives a written quote before any work begins, and the price agreed in that quote is the price billed.

Payment methods and billing

We accept credit and debit cards, and bank transfer (ACH or wire). Card payments are handled by our third-party payment processor; we do not store or have access to full card details on our own systems.

Projects are billed as an initial deposit followed by milestone invoices as agreed stages are delivered. Retainers and support plans are invoiced monthly in advance. Every payment is accompanied by an itemised invoice showing the work billed, and a receipt once payment is received. Invoices are payable within the period stated on them, which is normally 14 days.

How we deliver

All services are delivered digitally. No physical goods are shipped. Source code, designs, and related assets are delivered into a repository or workspace that you own and control, so you hold the work as it is produced rather than only at the end.

Deliverables are released against the milestones set out in your agreement, normally within five business days of a milestone being approved. Timelines are agreed in writing for each project, and we tell you promptly if anything changes.

Ownership and handover

On final payment for a milestone, ownership of the work delivered under that milestone transfers to you. At the end of an engagement we provide a complete handover of code, assets, and documentation, so you can continue with your own team or another provider without depending on us.

Your responsibilities

To keep delivery on schedule we need timely feedback, access to the systems and information the work depends on, and approval of milestones as they are completed. Where these are delayed, timelines may move accordingly.

Support after launch

Post-launch support and maintenance are available under a separate agreement. Where an agreed support plan is in place, we acknowledge support requests within one business day during business hours (Monday to Friday, 9:00 to 18:00, Mountain Time).

Confidentiality

We treat your business information, data, and systems as confidential, and use them only to deliver the agreed work.

Billing questions

If you have a question or concern about any charge, contact us at contact@arthussystems.com before raising a dispute with your bank or card issuer. We acknowledge billing enquiries within two business days, and most are resolved quickly once we can see the invoice and the agreement together. Contacting us directly is always faster than a dispute.

Cancellation and refunds

How cancellation works, and how deposits, work in progress, and prepaid amounts are treated, is set out in our Cancellation Policy and Refund Policy.

Governing law

These terms are governed by the laws of the State of New Mexico, United States, without regard to conflict-of-law rules.
