1. Accepting these Terms
By creating an account, accessing, or using DueTally, you agree to these Terms and our Privacy Policy. If you use DueTally for an organisation, you confirm that you can bind that organisation; "you" then includes both you and it.
You must have reached the age of legal majority where you live and have legal capacity to enter this contract. If you do not agree, do not use DueTally.
2. What DueTally does
DueTally helps users create and send invoices, payment requests, and payment links; manage clients and public receiving-wallet addresses; send reminders and receipts; create PDFs and exports; and monitor supported public blockchains for transactions that may match an amount due.
DueTally is non-custodial. We are not a wallet, exchange, bank, escrow agent, money transmitter, payment processor, tax adviser, or financial adviser. We do not hold, receive, transmit, exchange, recover, or control your funds. Your payer sends funds directly to the public wallet address you provide.
3. Accounts and security
- Provide accurate information and keep it current.
- Keep access to your email, Google account, devices, and DueTally session secure.
- Do not share an account in a way that defeats access controls or impersonates another person.
- Notify pedro@duetally.com promptly of suspected unauthorised access.
You are responsible for activity under your account unless caused by our breach of these Terms or failure to use legally required care. We may require reasonable verification before acting on account, privacy, or deletion requests.
4. Your responsibilities
You are responsible for:
- the legality, accuracy, and completeness of invoices, requests, payment links, client records, tax rates, wallet addresses, and messages you submit;
- checking the token, network, wallet address, amount, exchange rate, and transaction status before treating a payment as complete;
- having a lawful basis to store client and payer data and to email invoices, reminders, and receipts;
- honouring your contracts with clients, including refunds, credits, disputes, and delivery of goods or services;
- your taxes, accounting, sanctions screening, licensing, consumer, anti-money-laundering, and other regulatory duties; and
- keeping your own records and exports where the law or your business requires them.
DueTally’s detected, matched, confirmed, paid, or review statuses are workflow aids. They are not bank statements, legal settlement determinations, or guarantees that a transaction is final or belongs to a particular payer.
5. Blockchain and stablecoin risks
Blockchain transactions may be public, irreversible, delayed, reorganised, duplicated, misdirected, or affected by network congestion, smart-contract faults, RPC-provider errors, forks, exploits, sanctions, token issuer actions, or loss of a stablecoin’s value. A token described as a stablecoin may not remain redeemable or equal to its reference currency.
You and the payer must verify the destination address, token contract, and network. Funds sent to the wrong address, asset, or network may be unrecoverable, and DueTally cannot reverse or recover them. Supported assets and networks may change for security, technical, legal, or provider reasons.
6. Public pages and communications
Published invoices, requests, and payment links are accessible to anyone who has their public link. Do not place secrets, special-category personal data, or unnecessary confidential information on them. You control who receives each link, but links can be forwarded.
When you ask DueTally to send a message, you instruct us to send it on your behalf. You must identify yourself accurately, use truthful content, and comply with applicable electronic-communications and anti-spam rules. Service emails may be delayed, filtered, rejected, or forwarded by third-party systems.
7. Plans, billing, and taxes
Free Plan
The Free Plan includes up to five published invoices, payment requests, or payment links per calendar month. Drafts do not count. Reaching the limit does not remove existing history.
Paid Plan
The Paid Plan is USD $29 per month unless the checkout states otherwise. Stripe processes payment. The subscription renews automatically each month until cancelled. You authorise recurring charges, including applicable taxes disclosed at checkout. Exchange, bank, card, or foreign-transaction fees charged by others are your responsibility.
You can cancel through the Stripe customer portal available from DueTally or by contacting us. Cancellation stops future renewals and normally takes effect at the end of the paid billing period. Except for the withdrawal right below, a service failure, or where law requires otherwise, charges already paid are non-refundable and we do not provide prorated refunds.
We may change plan features or prices prospectively. We will give reasonable advance notice of a price increase affecting an existing subscription. Continued use after the effective date constitutes acceptance; you can cancel before the increase applies.
8. Consumer rights, governing law, and disputes
If you are an EU or EEA consumer, you may withdraw from a Paid Plan within 14 days after subscribing, without giving a reason. Email pedro@duetally.com before the deadline with a clear statement that you are withdrawing. You may use: “I give notice that I withdraw from my DueTally Paid Plan, ordered on [date], for [name and account email].” We will reimburse the subscription payment using the original payment method within 14 days after receiving your notice and may end Paid Plan access when the withdrawal is processed.
Consumers also retain all mandatory rights concerning digital-service conformity, remedies, unfair terms, jurisdiction, and other protections under the law that applies to them. Nothing in these Terms excludes or limits rights that cannot legally be excluded or limited.
These Terms are governed by Portuguese law, without regard to conflict-of-law rules. The courts of Lisbon, Portugal have jurisdiction, except that a consumer may rely on any mandatory law or court jurisdiction available where they habitually reside.
Please first contact pedro@duetally.com so we can try to resolve the issue. Consumers may also contact the Lisbon Consumer Conflict Arbitration Centreor another competent entity listed by Portugal’s Directorate-General for Consumers. We do not require private arbitration and these Terms do not prevent either party from seeking an available court remedy.
9. Acceptable use
You must not use DueTally to:
- break any law, sanctions restriction, court order, or third-party right;
- facilitate fraud, deception, money laundering, terrorist financing, unlawful gambling, trafficking, ransomware, or sales of prohibited goods or services;
- send unsolicited or misleading messages, impersonate others, or create fraudulent invoices or payment requests;
- upload malware, probe or bypass security, interfere with the service, scrape at abusive rates, or access another user’s data;
- reverse engineer the service except where applicable law expressly permits it; or
- resell or provide DueTally as a service bureau without our written permission.
We may investigate suspected abuse and preserve or disclose relevant information where legally permitted and reasonably necessary to protect users, the public, DueTally, or comply with law.
10. Your content and data
You retain ownership of information and content you submit ("Customer Data"). You grant us a limited, worldwide licence to host, copy, transmit, display, and otherwise process Customer Data only to operate, secure, support, and improve the service, comply with your instructions, and meet legal obligations.
You confirm that you have the rights and lawful basis needed to provide Customer Data and instruct its processing. Our Privacy Policy explains when we act as a controller and when we process client or payer data on your behalf. Section 19 contains the data-processing terms that apply where privacy law treats you as a controller and us as your processor.
11. DueTally intellectual property
DueTally and its software, design, branding, documentation, and service content are owned by us or our licensors. Subject to these Terms, we give you a limited, non-exclusive, non-transferable, revocable right to use the service during your account term. No other rights are granted.
If you provide feedback, you allow us to use it without restriction or payment, but we will not publicly identify you as its source without permission.
12. Third-party services
DueTally relies on third parties for authentication, hosting, email, billing, analytics, diagnostics, blockchain data, and block explorers. Their systems and terms may affect availability and processing. Links to third-party sites do not make us responsible for their content. Your direct use of a wallet, blockchain, Stripe checkout, Google account, or block explorer may also be governed by that provider’s terms.
13. Service changes and availability
We aim to keep DueTally reliable but do not promise uninterrupted or error-free service. We may maintain, modify, suspend, or discontinue features for operational, security, legal, or product reasons. Where reasonably possible, we will give advance notice of a material discontinuation and an opportunity to export relevant data.
14. Suspension and termination
You may stop using DueTally at any time. To request account closure and deletion, email pedro@duetally.com. Cancelling a paid subscription alone does not delete your account or history.
We may restrict or suspend access when reasonably necessary to address a security risk, non-payment, unlawful use, material breach, or risk of harm. We may terminate for a material breach that is not cured after reasonable notice, unless immediate action is reasonably necessary. On termination, your licence ends. Provisions intended by their nature to survive—including payment obligations, ownership, disclaimers, liability, disputes, and data-protection duties—continue to apply.
15. Disclaimers
To the maximum extent permitted by law, DueTally is provided “as is” and “as available.” We disclaim implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty that blockchain monitoring, matching, communications, or third-party services will be complete, timely, accurate, or uninterrupted.
This section does not affect mandatory consumer guarantees or liability that cannot be disclaimed under applicable law.
16. Limitation of liability
Nothing limits liability for fraud, wilful misconduct, death or personal injury caused by negligence, breach of mandatory data-protection duties, or any liability that law does not allow us to limit.
Otherwise, to the maximum extent permitted by law, we are not liable for indirect, incidental, special, exemplary, punitive, or consequential loss; loss of profit, revenue, goodwill, opportunity, or data; or loss caused by an incorrect wallet, token, network, irreversible transaction, stablecoin failure, blockchain event, or third-party service.
For non-consumer users, our total aggregate liability arising from DueTally or these Terms will not exceed the greater of USD $100 and the fees you paid to DueTally during the 12 months before the event giving rise to the claim. For consumers, liability is limited only to the extent allowed by mandatory applicable law.
17. Indemnity for organisational users
If you use DueTally for a trade, business, or organisation, you will defend and indemnify us against third-party claims, damages, and reasonable costs resulting from your Customer Data, your client relationship, your breach of Sections 4, 6, or 9, or your violation of law or third-party rights. This does not apply to the extent a claim was caused by us. This section does not apply to consumers acting outside a trade or profession.
18. Changes and general terms
We may update these Terms. We will post the revised version and update its date. We will give reasonable advance notice by email or in the service if a change materially reduces your rights or increases your obligations. Changes apply prospectively. If you do not agree, stop using DueTally and cancel before the change takes effect.
We may assign these Terms as part of a genuine reorganisation, financing, sale, or transfer of DueTally, subject to applicable law. You may not assign them without our consent. If one provision is unenforceable, the rest remain effective. A failure to enforce a provision is not a waiver. These Terms and documents expressly incorporated into them are the entire agreement about DueTally.
19. Data Processing Terms
This section applies when we process personal data contained in Customer Data on your behalf and the GDPR, UK GDPR, or a similar law requires controller–processor terms. It forms a data processing agreement ("DPA") between you as controller (or processor for another controller) and Pedro Silva, trading as Plainworks, as processor (or subprocessor).
Scope and instructions
The processing lasts while we provide DueTally and during limited deletion, backup, or legal-retention periods. Its subject is operating a receivables service: storing, organising, displaying, transmitting, exporting, emailing, and matching Customer Data and public-chain transactions. We process only on your documented instructions, including these Terms and your use of service features, unless law requires otherwise. If an instruction appears to violate data-protection law, we will inform you where permitted.
People and data
Data subjects may include your staff, clients, client contacts, invoice recipients, payers, and other people you add. Data may include names, contact and business details, billing addresses, invoice and line-item details, messages, public wallet addresses, transaction hashes and amounts, payment status, and related activity. DueTally is not intended for special-category data, criminal-offence data, government identifiers, private keys, seed phrases, or payment-card data in Customer Data, and you must not submit them.
Our duties
- Ensure people authorised to process Customer Data are bound by confidentiality.
- Maintain appropriate technical and organisational security measures proportionate to the risk, including access controls, transport encryption, secret management, logging, minimisation, backup and recovery measures, and vulnerability/dependency maintenance.
- Notify you without undue delay after becoming aware of a personal-data breach affecting Customer Data and provide reasonably available information needed for your legal duties.
- Taking account of the nature of processing, reasonably assist with data-subject requests, security obligations, breach notifications, DPIAs, and regulator consultations. You remain responsible for deciding how to respond.
- On termination or your verified request, delete or return Customer Data unless law requires retention. Residual backup copies remain protected and are deleted through the ordinary backup lifecycle.
- Provide information reasonably necessary to demonstrate compliance. Audits must be legally required, coordinated in advance, limited to relevant systems and confidential information, avoid disrupting the service, and—unless an audit identifies material non-compliance—be at your cost.
Subprocessors and transfers
You generally authorise the subprocessors identified in the Privacy Policy for hosting, database, authentication, email, billing support, diagnostics, analytics where acting on Customer Data, and blockchain infrastructure. We will require materially equivalent data-protection obligations and remain responsible for their processing to the extent required by law. We will post or communicate material subprocessor changes and allow a reasonable objection based on documented data-protection grounds.
Where Customer Data is transferred outside the EEA, UK, or another protected territory, we will use an applicable adequacy decision, the European Commission’s Standard Contractual Clauses, the UK Addendum, or another lawful safeguard. For an EEA restricted transfer from you to us that lacks another mechanism, the 2021 controller-to-processor Standard Contractual Clauses are incorporated with you as exporter, us as importer, optional docking, general written authorisation for subprocessors, Portuguese law, Portuguese courts, and this Section plus the Privacy Policy supplying the Annex details.
Your duties
You are responsible for lawful, fair, transparent collection; giving required notices; responding to rights requests; configuring the service appropriately; limiting access; and ensuring your instructions comply with law. If you are a processor, you confirm your controller authorises these Terms and our subprocessors.
