PARTMASH™ END USER LICENSE AGREEMENT

The EFI Store · Horsepower Connections LLC

Last updated: September 15, 2026 | Effective Date: ______________

This End User License Agreement ("Agreement") is between Horsepower Connections LLC, an

Arizona limited liability company doing business as The EFI Store ("Company," "we," "us"),

and the business entity subscribing to PartMash ("Customer," "you").

By creating an account, connecting any account, or using the Service, you agree to this

Agreement. If you are agreeing on behalf of a company, you represent that you are authorized to

bind it.

1. The Service

PartMash (the "Service") is subscription software that reads product, pricing, cost and

inventory data from systems you connect — including QuickBooks Online, Shopify, and supplier

price feeds — compares them, and, at your direction, writes changes back to those systems.

We may modify or improve the Service. We will not materially reduce core functionality you are

paying for during a paid term without notice and the option to cancel for a prorated refund.

2. License

Subject to this Agreement and payment of fees, we grant you a non-exclusive, non-transferable,

non-sublicensable right to access and use the Service for your own internal business purposes

during your subscription term.

You may not: resell, sublicense, or provide the Service as a service bureau to third

parties; reverse engineer, decompile, or attempt to derive source code; circumvent usage limits

or access controls; use the Service to build a competing product; or use it in violation of any

law or of the terms of any system you connect.

We retain all right, title and interest in the Service, including all software, models, and

documentation. No rights are granted except those expressly stated.

3. Accounts and Security

You are responsible for the accuracy of your registration information, for all activity under

your account, and for maintaining the confidentiality of your credentials.

4. Subscription, Fees, and Cancellation

Fees. Subscription fees, billing frequency, and any usage limits are those shown at the time

you subscribe. Fees are stated in US dollars and are exclusive of taxes.

Billing and renewal. Subscriptions renew automatically for successive periods until

cancelled. You authorize us and our payment processor to charge your payment method for each

renewal at the then-current rate.

Price changes. We will give at least thirty (30) days' notice before a price increase

takes effect. The new price applies from your next renewal; you may cancel before then.

Cancellation. You may cancel at any time, effective at the end of the current paid period.

Refunds. Fees already paid are non-refundable except where this Agreement expressly says

otherwise or where required by law.

5. Connected Accounts and Your Authority

The Service functions only when you connect third-party accounts ("Connected Accounts").

You represent that you are authorized to connect each Connected Account and to permit the

Service to read from and write to it. You are responsible for complying with the terms of each

connected provider.

You may disconnect at any time, from within the Service or from the provider's own

application-management page. On disconnection we immediately cease further access and revoke

the stored tokens. Deletion of data is governed by the Privacy Policy.

Third-party providers are not our subcontractors. We are not responsible for their

availability, accuracy, or acts. If a provider changes or withdraws its API, the affected

functionality may change or stop.

6. Changes the Service Writes — Your Review, Your Responsibility

This is the most important section of this Agreement. Read it.

The Service can propose and apply changes to prices, costs, product records, descriptions and

inventory levels in your live systems. Those systems face your customers and your accounting.

You are responsible for reviewing changes before they are applied. Where the Service offers

a review, preview, dry-run or approval step, you are responsible for using it. Where you enable

automatic application, you accept the results of that choice.

We do not guarantee that supplier or vendor data is correct. The Service reports what your

sources say. Supplier feeds contain errors — wrong prices, wrong pack quantities, wrong

descriptions, stale costs — and the Service can faithfully transmit an error that originated

upstream.

You are solely responsible for:

similar pricing obligation you owe a manufacturer or distributor;

7. Intuit and QuickBooks

Your use of QuickBooks Online through the Service is additionally subject to Intuit's own terms.

Intuit is not a party to this Agreement and has no liability for the Service.

We handle QuickBooks data as described in Section 5 of the Privacy Policy, including that we

do not sell it, do not use it to train models offered to third parties, and do not provide third

parties with access to it.

8. Your Data

You own your data. You retain all right, title and interest in product records, pricing,

cost and accounting data retrieved from your Connected Accounts or uploaded by you

("Subscriber Data").

You grant us a limited license to host, process, transmit and display Subscriber Data solely to

provide and support the Service, and to maintain the change history described in the Privacy

Policy.

Aggregated data. We may use de-identified, aggregated statistics that cannot reasonably be

used to identify you or your business. **We do not disclose your costs, margins, supplier

terms, or customer data to any other subscriber**, in aggregate or otherwise.

9. Confidentiality

Each party will protect the other's non-public information with at least reasonable care and

use it only as needed to perform under this Agreement. This does not apply to information that

is public, independently developed, or lawfully obtained elsewhere, or where disclosure is

legally compelled.

10. Availability and Support

We aim to keep the Service available and to respond to support requests promptly.

11. Beta and Pre-Release Features

Features identified as beta, preview or experimental are provided as-is, may change or be

withdrawn, and are excluded from any warranty or commitment in this Agreement.

12. Warranty Disclaimer

EXCEPT AS EXPRESSLY STATED, THE SERVICE IS PROVIDED **"AS IS" AND "AS AVAILABLE," WITHOUT

WARRANTIES OF ANY KIND**, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A

PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.

WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT DATA OBTAINED

FROM SUPPLIERS OR CONNECTED ACCOUNTS IS ACCURATE OR COMPLETE.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW:

No indirect damages. NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL,

CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST MARGIN, OR LOST

DATA, EVEN IF ADVISED OF THE POSSIBILITY.

Cap. OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THIS AGREEMENT WILL NOT

EXCEED THE FEES YOU PAID US IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE

CLAIM.

Pricing outcomes. WITHOUT LIMITING THE ABOVE, WE ARE NOT LIABLE FOR LOSSES ARISING FROM

PRICES SET, MARGINS REALIZED, SALES MADE OR NOT MADE, MAP OR UPP ENFORCEMENT ACTION, OR

SUPPLIER RELATIONSHIPS, WHETHER OR NOT THE UNDERLYING DATA CAME THROUGH THE SERVICE.

These limits do not apply to a party's fraud, willful misconduct, or gross negligence, or to

your obligation to pay fees.

14. Indemnification

You will defend and indemnify us against third-party claims arising from your Subscriber Data,

your use of the Service in breach of this Agreement, or your lack of authority over a Connected

Account.

We will defend and indemnify you against third-party claims that the Service, used as permitted,

infringes a US intellectual property right, and will pay damages finally awarded.

15. Term, Suspension and Termination

This Agreement runs while you hold an active subscription.

We may suspend or terminate for material breach not cured within thirty (30) days of

notice, for non-payment, or immediately where continued use poses a security or legal risk to

us, to Intuit, or to another provider.

On termination: your access ends, we cease accessing your Connected Accounts, and stored

tokens are revoked. Data deletion follows the Privacy Policy.

16. Governing Law and Disputes

This Agreement is governed by the laws of the State of Arizona, without regard to conflict

of laws rules. The parties submit to the exclusive jurisdiction of the state and federal courts

located in Maricopa County, Arizona.

17. General

Entire agreement. This Agreement and the Privacy Policy are the entire agreement between the

parties on this subject.

Changes. We may update this Agreement. Material changes take effect on your next renewal, or

thirty (30) days after notice, whichever is later. Continued use after that constitutes

acceptance.

Assignment. You may not assign without our consent. We may assign in connection with a

merger, acquisition, or sale of assets.

Severability and waiver. If a provision is unenforceable, the rest remains in effect. A

failure to enforce is not a waiver.

Force majeure. Neither party is liable for delay or failure caused by events beyond its

reasonable control.
