Terms of Service

Last updated: August 31, 2026

These Terms of Service (“Terms”) govern access to and use of Argumentum (the “Service”), provided by Andrew Comer, a sole proprietor doing business as Tenpenny Software (“Tenpenny Software,” “we,” “us,” or “our”) to merchants using Shopify (“you” or “merchant”). By installing, accessing, or using Argumentum, you agree to be bound by these Terms. If you do not agree, do not install or use the Service.

1. Acceptance of these Terms

You must have the authority to bind the merchant on whose behalf you are installing Argumentum, and to grant Argumentum the Shopify access scopes it requests during installation. If you are using Argumentum on behalf of a business, you represent that you are authorized to accept these Terms for that business, and “you” refers to that business.

2. Description of the Service

Argumentum helps merchants capture and organize evidence for payment disputes (chargebacks). It watches order, fulfillment, and tracking events as they happen, lets you log communication with customers and, on Standard and Pro plans, attach supporting screenshots or documents to an order, and assembles a draft evidence packet for each dispute that you review, edit, and export. Argumentum detects disputes on Shopify Payments automatically, and, if you connect your own Stripe account, can detect and document disputes on that account too. (PayPal support is planned but not yet available — see Section 8.) Argumentum is a documentation and readiness tool — for a Shopify Payments dispute, it does not submit evidence to Shopify Payments, a card network, or any other party on your behalf, and you remain solely responsible for submitting it yourself. The one exception is the optional direct-submission feature described in Section 7, available only for a Stripe account you’ve connected and only when you take the specific action described there.

3. Eligibility and your account

  • You must have an active Shopify store. Dispute detection works automatically for Shopify Payments; detecting and documenting disputes on a Stripe account requires you to separately connect that account to the Service through Stripe’s own sign-in.
  • You are responsible for the accuracy of the information in your store (order, customer, and fulfillment records) that Argumentum reads and uses to build evidence packets.
  • You are responsible for maintaining the security of your own Shopify account and staff access, and for any activity that occurs under your store’s use of the Service.
  • Access to Argumentum ends automatically when the app is uninstalled from your Shopify store.

4. Subscription plans and billing

Argumentum is offered on the following plans, billed and managed entirely through Shopify’s own billing platform (Shopify App Pricing). We do not separately collect or process your payment details — Shopify bills you directly, and Shopify’s own merchant terms govern that billing relationship.

Plan Price Usage
Free $0/month Hard limit of 30 orders processed per month — no usage-based charges
Standard $9/month First 300 orders processed per month included; $0.050 per order beyond that
Pro $29/month First 3,000 orders processed per month included; $0.010 per order beyond that

Attaching screenshots or documents to an order (Section 2) is available on Standard and Pro only; it is not available on the Free plan.

Every new installation begins with a 14-day trial with full access to the Service, regardless of which plan you later choose. Near the end of the trial, we’ll email a plan recommendation based on your store’s order volume during the trial, but you choose your own plan through Shopify’s hosted pricing page.

The Free plan has a hard monthly order-volume limit. If your store consistently processes more orders than the Free plan’s limit for 5 consecutive daily checks, we will notify you and provide a grace period (currently 14 days) to upgrade. If the grace period lapses without an upgrade, creation of new evidence packets may be paused until you upgrade — evidence packets you’ve already generated remain fully accessible, editable, and exportable regardless of plan or billing status. Every other plan has no such hard limit: orders beyond a plan’s included monthly volume are billed automatically through that plan’s own Shopify usage meter, and nothing is ever paused for exceeding it.

If a paid plan’s metered overage consistently costs more than the next plan’s flat monthly fee for 5 consecutive daily checks, or if your store’s order volume stays well under your current plan’s included allowance for 30 consecutive daily checks, we’ll send an informational suggestion to switch plans — neither of these is ever gating, and nothing is changed automatically. These thresholds are part of the Service’s own plan-recommendation logic, not a Shopify billing rule, and may change with notice as described in Section 14.

Metered overage is billed automatically through each paid plan’s own Shopify usage meter; you do not need to take any action for usage billing to apply. Except as required by applicable law, fees already billed by Shopify are non-refundable.

5. Acceptable use

You agree not to:

  • Use the Service to prepare or submit evidence you know to be false, misleading, or fabricated, including in connection with disputing a charge you know to be valid.
  • Use the Service in a way that violates Shopify’s Acceptable Use Policy, API License and Terms of Use, or Partner Program Agreement.
  • Attempt to interfere with, disrupt, reverse-engineer, or gain unauthorized access to the Service or its underlying infrastructure.
  • Use the Service to process personal information you are not lawfully entitled to process, or in a manner that violates applicable data protection law.
  • Resell, sublicense, or provide the Service to a third party as your own standalone offering.

6. Your data and content

As between you and Tenpenny Software, you own the order, customer, fulfillment, and dispute data from your store, the communication-log notes and evidence-packet edits you or your staff enter into the Service, and any attachments (screenshots or documents) you or your staff upload (“Your Data”). You grant Tenpenny Software a limited license to access, store, and process Your Data solely to provide and maintain the Service, as described in our Privacy Policy, which is incorporated into these Terms by reference. Our Data Processing Addendum sets out the formal terms of that processing (including Standard Contractual Clauses for international transfers) and is incorporated into these Terms the same way.

You represent that you have the necessary rights and permissions to provide Your Data to Argumentum, including any personal information about your customers, and that doing so complies with your own privacy obligations to those customers. If you connect a third-party payment processor (currently: Stripe — see Section 8 on PayPal) to the Service and direct us to transmit Your Data to it, you represent that you’re authorized to connect that account and to direct that transmission.

7. No automated submission; no guaranteed outcomes

Argumentum is a documentation and organization tool, not an automated dispute-resolution service. We never submit anything on your behalf automatically — not on a deadline, not based on any signal, not without your explicit action every single time. For Shopify Payments disputes, the Service does not submit evidence directly at all — every evidence packet requires your review and an affirmative export step, and you submit it yourself through Shopify. For a dispute on a Stripe account you connect, the Service offers an optional direct-submission feature: after you review the evidence the Service has assembled and affirmatively acknowledge what you’re about to send, we transmit it to Stripe. (PayPal support, including an equivalent direct-submission capability, is planned but not yet available — see Section 8.)

Submission through this feature is final and one-time only. Once submitted, Stripe’s own rules govern what happens next — a submission cannot be undone, amended, or resubmitted through the Service, and we have no ability to alter or retract it afterward, regardless of what Stripe’s own systems might independently permit.

In every case, you are solely responsible for the accuracy and completeness of anything you approve for direct submission, and for confirming actual dispute deadlines and requirements directly with your payment provider.

We make no representation or warranty that using the Service — including the direct-submission feature — will result in a favorable dispute outcome, that any evidence packet is complete or sufficient for a particular dispute, or that any deadline, readiness indicator, order-match suggestion, or automated signal (including the billing-address/location match signal described in our Privacy Policy) is accurate or exhaustive.

8. Third-party services and Shopify’s own terms

Argumentum is built on and operates within the Shopify platform. Your use of Shopify itself, including Shopify Payments, is governed by Shopify’s own merchant terms of service, separate from these Terms. Argumentum also relies on third-party service providers (database hosting, cloud storage, email delivery, and an IP geolocation lookup) to operate — see our Privacy Policy for the current list and what each is used for. We are not responsible for the availability or performance of Shopify or any third-party provider we rely on, though we’ll make reasonable efforts to keep the Service working around any disruption.

If you choose to connect Stripe to the Service, your use of Stripe is governed by your own agreement with it, entirely separate from these Terms — we are not a party to it and are not responsible for Stripe’s decisions, availability, or handling of anything you submit to it.

PayPal support is planned but not yet available. We have built the capability to detect and document disputes on a merchant’s own connected PayPal account and to submit evidence to it directly, but this feature is switched off pending PayPal’s own approval of Tenpenny Software as an integration partner — an external process outside our control, with no guaranteed timeline. You cannot currently connect a PayPal account through the Service. We will update these Terms with the specifics of that connection and submission process before the feature becomes available to any merchant.

9. Intellectual property

Tenpenny Software owns all right, title, and interest in and to the Service, including its software, design, and the Argumentum name and branding, excluding Your Data. Subject to these Terms, we grant you a limited, non-exclusive, non-transferable license to access and use the Service for your own business purposes for as long as your subscription is active. Nothing in these Terms transfers any ownership of the Service to you.

10. Term, suspension, and termination

These Terms remain in effect for as long as you use the Service. You may stop using the Service, and end these Terms, at any time by uninstalling Argumentum from your Shopify store.

We may suspend or terminate your access to the Service if you violate these Terms (including Section 5), if required to do so by Shopify or applicable law, or if your subscription falls into non-payment through Shopify’s billing platform. Where reasonably possible, we will provide notice before suspending or terminating access for cause.

On termination, your right to use the Service ends immediately. Section 4 (fees already due), Section 6 (data ownership), Sections 11-13 (disclaimers, liability, indemnification), and Section 15 (governing law) survive termination. Data retention and deletion after termination are described in our Privacy Policy.

11. Disclaimer of warranties

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR SECURE, OR THAT ANY EVIDENCE PACKET, READINESS INDICATOR, DEADLINE, OR OTHER OUTPUT OF THE SERVICE WILL BE ACCURATE, COMPLETE, OR SUFFICIENT FOR ANY PARTICULAR DISPUTE OR PURPOSE.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, TENPENNY SOFTWARE WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR BUSINESS OPPORTUNITY — INCLUDING ANY LOSS ARISING FROM A LOST OR UNSUCCESSFUL PAYMENT DISPUTE, A MISSED DEADLINE, OR AN INACCURATE OR INCOMPLETE EVIDENCE PACKET — EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. TENPENNY SOFTWARE’S TOTAL LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE WILL NOT EXCEED THE AMOUNT YOU PAID TO SHOPIFY FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM. Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above limitations may not apply to you.

13. Indemnification

You agree to indemnify and hold Tenpenny Software harmless from any claim, liability, damage, loss, or expense (including reasonable legal fees) arising out of or related to: your use of the Service in violation of these Terms; Your Data, including any personal information you provide to the Service without the necessary rights or permissions; or your violation of any applicable law.

14. Changes to the Service or these Terms

We may modify or discontinue features of the Service, and may update these Terms, from time to time. We will revise the “Last updated” date above when we do, and where a change is material, we will take reasonable steps to notify you (for example, by email or an in-app notice) before it takes effect. Continued use of the Service after a change takes effect constitutes acceptance of the updated Terms.

15. Governing law and dispute resolution

These Terms are governed by the laws of the State of Washington, United States, without regard to its conflict-of-laws principles. You and Tenpenny Software agree to submit to the personal jurisdiction of, and venue in, the state and federal courts located in Yakima County, Washington, for any dispute arising out of or relating to these Terms or the Service not otherwise resolved informally.

16. General provisions

  • Entire agreement. These Terms, together with our Privacy Policy, are the entire agreement between you and Tenpenny Software regarding the Service, and supersede any prior agreements regarding the Service.
  • Severability. If any provision of these Terms is found unenforceable, the remaining provisions remain in full effect.
  • No waiver. Our failure to enforce any provision of these Terms is not a waiver of our right to do so later.
  • Assignment. You may not assign these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, or sale of assets.
  • Force majeure. Neither party is liable for delay or failure to perform caused by circumstances beyond its reasonable control.
