Terms of Use
Crest Invoice is a personal software project operated by the Crest Invoice Team: Alina Riaby and Pavel Riaby.
These terms apply when you use Crest. By choosing a feature, you ask Crest to perform that feature under these terms. The Privacy Policy explains personal data processing. Contact support@crest-invoice.com with questions.
Service and eligibility
Crest is a free, early-stage invoice software project. It lets you create and download invoices and, when offered, opt into hosted, sending, access and status features. It is not a payment, legal, tax or accounting service.
You must be 18 or older, have legal capacity, and have authority to issue the invoice or act for its sender. You must also have authority to provide any client or other personal data you enter.
Crest may change, suspend or discontinue a feature as the early-stage service evolves. Where practicable, Crest will give reasonable notice of a material change and provide a feasible way to save or export affected invoices first.
User responsibility
You are responsible for the accuracy and lawfulness of invoice identities, items, tax, currency, totals, dates, payment instructions, client data and delivery. Required invoice fields and recordkeeping differ by jurisdiction and transaction. Crest guides provide general information, not legal, tax or accounting advice; check the rules that apply to you and use a qualified adviser when needed.
You confirm that you have a lawful basis or other authority to enter client personal data and send the invoice, and that you will follow applicable privacy and marketing rules. Check the final PDF or Live Invoice before sending and preserve the records the law requires.
Payments and third parties
Crest displays payment instructions or external links supplied by the invoice creator and can record a reported status. Crest does not receive, hold, route, settle or guarantee funds and is not a payment processor.
Any bank or payment-provider relationship, availability, fees, exchange rates, fraud controls, refund or dispute is between the relevant parties and provider. A client's payment report is not proof of bank settlement. The invoice sender must verify receipt independently.
Third-party links and services have their own terms and privacy practices. Crest is responsible for its own software and processing, not for a third party's independent service.
Acceptable use
Do not use Crest to:
- create or send unlawful, deceptive, fraudulent, infringing or abusive invoices;
- distribute malware, phishing, spam or harassment;
- impersonate a person or organisation, or use personal data without authority;
- probe, bypass or interfere with security, access controls or rate limits;
- run automated scraping or load that harms the service or other users; or
- violate a relevant provider's rules or applicable law.
Crest may investigate and proportionately restrict abusive use. Where feasible and lawful, Crest will preserve a way for the affected user to obtain their lawful data.
IP, termination and availability
You retain rights in the invoice and other content you provide. You grant Alina Riaby and Pavel Riaby only the limited licence needed to render, host, send and operate the feature you request. Crest retains rights in its software, site, documentation and brand, subject to any stated open-source or third-party licence.
You may stop using Crest at any time and delete hosted data through available controls or support@crest-invoice.com. Crest may suspend or terminate access for a material breach, abuse, a security need or a legal requirement. Data is then deleted or isolated under the Privacy Policy, subject to narrow legal evidence and backup expiry.
Crest is provided without an uptime promise. Planned maintenance, unexpected failure, provider interruption or early-stage feature change can make it temporarily unavailable. Save important final invoices and records outside the service.
Disclaimers, liability and disputes
To the extent the law permits, Crest provides the early-stage service and its general-information guides without a promise that every feature will be uninterrupted, error-free or suitable for a particular legal, tax or payment outcome. You remain responsible for checking invoices and payment receipt.
Nothing in these terms excludes or limits responsibility for fraud, wilful misconduct, gross negligence, death or personal injury where caused, mandatory consumer rights, data-protection responsibility, or anything else that cannot lawfully be excluded. Mandatory rights prevail over inconsistent wording in these terms. Crest does not set an artificial monetary liability cap for this free service.
Serbian law governs these terms to the extent that a mandatory law does not require otherwise. Before starting court proceedings, contact support@crest-invoice.com so the issue can be addressed in good faith where appropriate. This does not restrict mandatory consumer, data-protection, jurisdiction, complaint or court rights, and these terms do not require an exclusive court or arbitration venue.
Contact and versioning
Contact the operators at support@crest-invoice.com.
The effective date and version appear at the top. Material changes will receive appropriate notice, and prior versions will remain retrievable. Continued use does not accept a new purpose or obligation where the law requires a separate agreement. A future paid subscription or payment service will require separate terms before it is offered.
