Terms of Service

Effective 2026-09-27 · Mobile Invoices is a product of Stacked Systems LLC

1. Who we are and what you’re agreeing to

Mobile Invoices (the “Service”) is a product of Stacked Systems LLC (“we”, “us”, “our”), an Indiana limited liability company. Mobile Invoices is the name of the product, not a separate company or business name: these Terms of Service (the “Terms”) are an agreement between you and Stacked Systems LLC, which operates the Service, bills you for it under its own name, and is the party responsible to you under these Terms. By creating an account or using the Service you agree to these Terms and to our Privacy Policy. If you don’t agree, don’t use the Service.

These Terms cover Mobile Invoices only. Other products from Stacked Systems LLC are separate services with their own terms. If you use the Service for a business, you’re agreeing on that business’s behalf, you confirm you have authority to do so, and “you” includes that business.

2. The Service

Mobile Invoices lets solo contractors build an estimate or invoice on their phone and text the client a clean mobile page — with their own Venmo, Zelle, Cash App, and PayPal details on it. No card processing, no percentage fees. We host your documents and show your own payment details on them; the rest is between you and your customer. We may change, add, or remove features as the product develops. If a change materially reduces what you’re paying for, we’ll tell you before it takes effect.

The Service is operated from the United States and is intended for businesses in the United States. We make no promise that it’s appropriate or available anywhere else.

3. Eligibility and your account

You must be at least 18 and able to enter a binding contract, and you may use the Service only for business purposes — estimating and invoicing your own customers. You need an account. Keep your password secure and your account email current; you’re responsible for everything done under your account. Tell us promptly at hello@mobileinvoices.app if you think it’s been compromised.

Give us accurate information, including your business name and the payment details you choose to show on your documents. You may not use the Service if we’ve previously terminated your account.

4. Your content and your customers’ information

You keep all rights to what you put into the Service — your business details, logo, clients, saved items, and documents (“Your Content”). You give us a non-exclusive, worldwide, royalty-free license to host, store, copy, display, and transmit Your Content solely to operate, secure, and improve the Service for you, including showing your documents to the people you share them with. We don’t sell Your Content and don’t use it to train AI models.

Your Content includes information about other people — your customers’ names and contact details. You confirm you have the right to give us that information, you’re responsible for handling it lawfully and keeping it accurate, and you’ll tell those people how it’s used where the law requires. You also confirm Your Content doesn’t infringe anyone’s rights or break any law.

You send your own messages. The Service gives you a link; you deliver it by text, email, or however you choose, from your own phone or accounts. We don’t send messages to your customers on your behalf. You’re responsible for those messages, including having any consent the law requires for them (for example under the TCPA for text messages) and honoring requests to stop.

5. Documents, share links, and the client portal

Every finalized document gets a private, unguessable link, and every client gets a portal link listing the invoices you’ve sent them. Anyone who has one of those links can open it without signing in, so share links only with the people who should see them. Links stay live until the document or your account is deleted. Once a document is finalized it can’t be edited — duplicate it and send a new one instead. Drafts can be edited or deleted freely.

You’re responsible for what your documents say: the accuracy of descriptions, quantities, prices, and totals; any tax you charge; and compliance with the laws, licensing rules, and invoicing requirements that apply to your trade and location. We don’t review your documents, and nothing in the Service is legal, tax, or accounting advice.

6. Payments between you and your customers

Mobile Invoices doesn’t process payments. Your documents display the payment details you enter — for example your Venmo, Zelle, Cash App, or PayPal information — and your customers pay you directly through those services. We aren’t a party to those payments; we never receive, hold, or transmit your customers’ money; and we’re not a payment processor, money transmitter, or bank. “Zero fees” means we don’t charge a fee on those payments. The payment services you use have their own terms and may charge their own fees.

Enter your payment details carefully. We can’t recover money sent to a wrong or outdated handle, and we’re not responsible for payments that fail, are delayed, or go astray on a third-party service. Disputes about work, amounts, or payment are between you and your customer.

7. Plans, billing, and the free tier

Free tier. The free tier includes 5 documents per calendar month, estimates and invoices combined. A document counts when it’s created: drafts, documents you later delete, and invoices converted from estimates all count toward the limit. The count resets at the start of each calendar month. Every feature is included on the free tier; volume is the only limit, and we may change the limit with notice.

Paid plan. Mobile Invoices Pro removes the monthly limit. It costs $20.00 per month or $200.00 per year, billed in advance by Stacked Systems LLC through our payment processor, Stripe. Subscriptions renew automatically at the end of each billing period until you cancel. Prices are in US dollars and exclude sales, use, and similar taxes; if we’re required to collect tax on your subscription we’ll add it at checkout.

What you’ll see on your statement. Because Stacked Systems LLC is the business you’re paying, Stripe’s checkout page, your receipts, and the billing portal all show Stacked Systems LLC — not Mobile Invoices — and the charge appears on your card statement as STACKED SYSTEMS LLC. Your receipt lists Mobile Invoices Pro as the item. If you see a charge from Stacked Systems LLC you don’t recognize, it’s your Mobile Invoices subscription — email us before disputing it.

Cancelling and refunds. You can cancel any time from Settings → Manage billing. Cancellation takes effect at the end of the current billing period: you keep Pro until then, and afterwards your account returns to the free tier with all of your existing documents intact. Except where the law requires otherwise, fees are non-refundable and we don’t prorate partial periods — but if something has gone wrong, email us before disputing a charge; we’d rather sort it out. If you dispute a charge with your card issuer without contacting us first, we may suspend the account until it’s resolved.

Failed payments. If a renewal payment fails, Stripe will retry it. While a payment is past due your account is treated as free tier for creating new documents; if the payment can’t be collected, the subscription is cancelled.

Price changes and promotions. We may change prices with at least 30 days’ notice by email or in the app. Changes take effect at your next renewal and never apply to a period you’ve already paid for. Promotional codes are subject to their stated conditions and may be withdrawn.

8. Acceptable use

Don’t use the Service to break the law; to send spam or unsolicited messages; to create fraudulent, misleading, or fake documents; to infringe anyone’s rights; to upload malware; or to attack, probe, scrape, or overload our systems or our providers’. Don’t share your account, resell or relabel the Service, or reverse-engineer it without our written permission. We may suspend or terminate accounts that do these things, and we may remove content that violates these Terms or the law.

9. Our intellectual property and your feedback

The Service — its software, design, and name — belongs to Stacked Systems LLC and its licensors and is protected by intellectual-property laws. These Terms don’t give you any right to it beyond using the Service as intended. Pages you share may carry a small “Sent with Mobile Invoices” line. If you send us feedback or suggestions, we may use them without any obligation to you.

10. Availability and changes to the Service

The Service is provided on an as-available basis with no uptime guarantee or service-level agreement. This is an early-stage product: there may be downtime, bugs, and changes, and we may discontinue the Service. If we discontinue it or remove a major feature, we’ll give you reasonable notice — at least 30 days where practical — and a way to export your data. We recommend keeping your own copies: Settings offers CSV exports of your documents and clients, and every document can be downloaded as a PDF.

11. Disclaimers

To the fullest extent the law allows, the Service is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We don’t warrant that the Service will be uninterrupted, error-free, or secure, that a document will be delivered or opened, or that your customers will pay you. Nothing in the Service is legal, financial, tax, or accounting advice. Third-party services you use alongside the Service — payment apps, your phone’s messaging, your email — are outside our control and governed by their own terms.

12. Limitation of liability

To the fullest extent the law allows, Stacked Systems LLC and its members, managers, employees, and providers are not liable for any indirect, incidental, special, consequential, or punitive damages, or for lost profits, revenue, business, goodwill, or data, arising out of or relating to the Service or these Terms, however caused and under any theory of liability, even if we’ve been told such damages are possible. Our total liability for all claims relating to the Service is limited to the greater of the amount you paid us in the twelve months before the claim arose or fifty US dollars ($50). These limits reflect how inexpensive the Service is. Some jurisdictions don’t allow some of these limits, in which case they apply only to the extent permitted, and nothing here limits liability that can’t be limited by law.

13. Indemnification

You’ll defend, indemnify, and hold harmless Stacked Systems LLC and its members, managers, employees, and providers from claims, damages, and expenses (including reasonable attorneys’ fees) arising out of Your Content, your documents and the transactions they describe, your messages to your customers, your use of the Service, or your breach of these Terms or the law. We’ll notify you promptly of any such claim and may take over its defense at our own expense.

14. Termination

You can stop using the Service and delete your account at any time from Settings. Deletion is immediate and permanent: it cancels any subscription, removes your documents, clients, saved items, and logo, and disables every link you’ve shared. Export what you need first.

We may suspend or terminate your account if you materially breach these Terms, if your subscription remains unpaid, if we’re required to by law, or if we discontinue the Service. Where practical we’ll warn you first and give you a chance to export your data. On termination your right to use the Service ends. Sections that by their nature should survive — including 4, 6, 9, and 11 through 17 — survive.

15. Governing law and disputes

These Terms and any dispute relating to the Service are governed by the laws of the State of Indiana, United States, without regard to conflict-of-law rules.

If you have a problem, email hello@mobileinvoices.app first and give us 30 days to work it out with you informally — most issues are resolved this way. If we can’t, any dispute must be brought exclusively in the state or federal courts located in the State of Indiana, and you and we each consent to their jurisdiction and venue. Either of us may instead bring an individual claim in small-claims court where permitted. Any claim must be filed within one year after it arose, unless the law doesn’t allow that period to be shortened. If you’re a consumer whose home law gives you rights this section can’t take away, those rights aren’t affected.

16. Changes to these terms

We may update these Terms as the product changes. If a change is material, we’ll give at least 14 days’ notice by email or in the app before it takes effect, except where a change is required by law or only covers a new feature, in which case it may take effect immediately. Continuing to use the Service after the effective date means you accept the updated Terms; if you don’t, delete your account before then. The current version is always on this page, with its effective date at the top.

17. General

These Terms, together with the Privacy Policy, are the entire agreement between you and Stacked Systems LLC about the Service and replace any earlier agreements. If any part is found unenforceable, the rest still applies. If we don’t enforce a provision, we haven’t waived it. You may not assign these Terms without our consent; we may assign them to a successor of the Service or of our business, and we’ll tell you if we do. Neither of us is liable for delays or failures caused by events outside our reasonable control. Nothing here creates a partnership, employment, or agency relationship. We’ll send notices to the email address on your account; you can send notices to us at the address below. You’ll comply with US export and sanctions laws in using the Service.
