Terms of Service
1. Our services and business context
Parkhurst Interface provides website wireframe planning, interface design, user journey and navigation review, interactive prototype development, and interface standards and design documentation. Services are intended to help businesses plan and communicate digital experiences. Work may be ordered as a focused engagement or a combination of agreed services.
Descriptions on this website identify typical service categories. They do not promise that every engagement includes every page, screen, device layout, component, research activity, prototype transition or documentation item. Those details belong in a written proposal, statement of work or other expressly accepted project agreement.
2. Who may use the website
You may use the website for lawful business evaluation, communication and related purposes. If you submit a request on behalf of an organization, you should have authority to provide the information and discuss the proposed engagement. A person authorizing paid work must have the authority required to bind the relevant client.
Do not use the website to submit misleading information, impersonate another person, transmit malicious code, attempt unauthorized access, interfere with hosted functions or infringe another person's rights. We may restrict misuse as reasonably necessary to protect the website, other users and our business operations.
3. Inquiries and acceptance of a project
Submitting a form asks us to review your information and respond. A submission confirmation means the form response has been successfully processed by the website; it does not mean that a paid project, delivery date, reservation or final price has been accepted. The form does not collect payment or place an item into a shopping cart.
An engagement begins only through the acceptance method stated in a written proposal or agreement. This may include an agreed approval and any payment or materials identified as a condition of starting. We may ask for clarification, propose a different scope or decline work that is outside our services or availability.
4. The written scope and order of documents
The project agreement should identify the client, services, pages or screens, relevant states and device layouts, deliverables, review rounds, schedule, fee, payment milestones and any important assumptions. If an item is important to the intended outcome, it should be stated clearly before the work is authorized.
A signed or otherwise validly accepted project agreement controls project-specific matters to the extent it expressly changes these general terms. Mandatory law takes priority. If documents conflict or leave an important point unclear, the parties should resolve it in writing before relying on an interpretation or beginning additional work.
5. Estimates and prices
The listed ranges are indicative U.S. dollar fees: $300–$700 for wireframe planning, $600–$1,500 for interface design, $250–$600 for a user journey and navigation review, $400–$1,000 for a prototype and $350–$900 for a documentation package. The actual quote depends on the agreed work and may differ when the required scope changes.
A written proposal identifies the fee and any applicable taxes, authorized expenses or separately priced services. No hourly rate, automatic discount, deposit percentage, recurring charge or third-party purchase is implied merely by visiting the website. Additional charges require an applicable agreement or other lawful authorization.
6. Client information and cooperation
The client is responsible for providing accurate business context, intended user tasks, relevant content, existing assets and timely consolidated feedback. The client should identify one person authorized to coordinate decisions unless a different approval structure is agreed. Requirements affecting accessibility, security, regulated content or implementation should be raised at the outset.
You are responsible for the rights and permissions needed for materials you supply. Please avoid sending unnecessary personal or confidential information and use test data where suitable. Delayed or incomplete inputs can affect the design and schedule; material consequences should be discussed rather than treated as silently accepted.
7. Design reviews and changes
Review rounds are opportunities to evaluate specified deliverables against the agreed direction and scope. Feedback should identify the relevant screen or element and the reason for the requested adjustment. The included number of rounds, response periods and any milestone approval process should be recorded in the proposal.
New pages, substantially different user flows, revised functionality, additional device layouts or a new visual direction may be a scope change. We should describe the change and its effect on price, timing and deliverables before performing chargeable additional work. An informal discussion does not by itself authorize unlimited revisions.
8. Timing, dependencies and delivery
Project dates are based on the agreed scope, available inputs and review schedule. The agreement should distinguish targets from any firm commitments and identify relevant dependencies. We do not promise a universal turnaround period for all projects or immediate availability based on the website alone.
Deliverables are provided in the agreed digital formats and through an agreed delivery method. Handoff may include design files, exports, an interactive prototype or documentation depending on the scope. Development, live-site deployment, ongoing hosting and maintenance are separate unless expressly included.
9. Prototypes, demonstrations and implementation
A prototype demonstrates intended interactions and selected transitions. It may use representative content and simulated states to support discussion before implementation. It is not a production system, and it should not be used to process actual payments, sensitive information or operational transactions unless separately developed and authorized for that purpose.
The process demonstration on this website is an explanation of our approach. It is not presented as a completed client engagement, a testimonial or evidence of a commercial outcome. The presence of six demonstrated stages does not add those stages to every service package.
10. Intellectual property and confidentiality
Rights in final deliverables, editable source files, pre-existing materials and third-party assets are governed by the project agreement and Intellectual Property Policy. File possession or payment alone does not replace any signed instrument required for an assignment of copyright. Licenses for fonts, images and other third-party resources must be respected.
We use project information for relevant business and service purposes. If either party requires a non-disclosure agreement or specific confidentiality procedure, it should be agreed before restricted materials are transferred. No client-identifying project material is automatically authorized for portfolio publication by a general website inquiry.
11. Payment, cancellation and disputes
Payment methods, due dates, deposits and milestone amounts must be stated in the proposal or invoice. We do not request payment-card details through the general inquiry form. The Payment & Billing Policy explains how questions about invoices and authorized work should be raised.
A cancellation should be communicated in writing so the parties can identify the effective date, work completed, outstanding commitments and any unused prepaid amounts. Refunds are assessed under the written agreement, Cancellation & Refund Policy and applicable law. An invoice dispute should identify the charge and the reason for questioning it so that it can be reviewed.
12. Professional judgment and limits of the engagement
UX/UI work involves judgment about information, structure, visual hierarchy and interaction. Recommendations are based on the materials, scope and assumptions available for the engagement. We do not guarantee increased sales, conversion, traffic, search placement, funding, regulatory approval or another business result.
A general usability review is not an accessibility certification, security audit, legal opinion or complete assessment of every user group. If formal testing, a particular technical standard or specialized review is required, its method and scope must be expressly agreed. The client and development team remain responsible for implementation decisions outside our agreed role.
13. Responsibility and mandatory protections
Each party is responsible for its own acts, materials and obligations within the agreed engagement. To the extent permitted by applicable law, a party is not responsible for losses that are outside the legally recoverable consequences of its conduct or arise from matters beyond its agreed role. Project-specific allocations of risk should be set out clearly in the project agreement.
Nothing in these terms excludes liability or removes a remedy that applicable law does not allow to be excluded or removed, including applicable protections concerning fraud, intentional misconduct or other non-waivable rights. A disclaimer on this website should not be read as a promise that every legal claim or mandatory obligation can be waived.
14. Iowa law and resolution of concerns
Subject to mandatory law that applies to a particular client or transaction, these terms and the general service relationship are governed by the laws of the State of Iowa, without applying choice-of-law rules to displace non-waivable protections. Any court proceeding must be brought in a court with proper jurisdiction and venue under the applicable agreement and law.
Please first send a clear written explanation of a concern and the resolution you seek so that it can be investigated. This request for communication does not prevent a person from using a lawful remedy or meeting a required legal deadline. We do not identify a particular county as mandatory venue merely from our mailing address.
15. Website availability, changes and contact
We may update website content, service descriptions and these terms. Changes do not automatically amend an already accepted project agreement; that agreement's amendment rules and applicable law continue to apply. Technical maintenance, platform issues or circumstances outside our reasonable control can affect website availability.
The date above identifies this version. If part of these terms is unenforceable, the remaining provisions apply to the extent permitted by law. Questions about a proposed engagement, an existing project or these terms may be sent through the on-site inquiry form or directed to the contact details below.
