The contract between you and GSTFiler.
Plain-English where we can, precise where we must. These Terms explain what we will do for you, what we ask of you in return, and where each of us stands when something goes wrong.
These Terms apply from the Effective Date above. If you signed up before that date on an older version, the older version continues to govern your subscription until your next renewal or until you accept these revised Terms in-app, whichever comes first. Words that begin with a Capital Letter are defined where they first appear.
01About these terms
These Terms of Use (the “Terms”) are a binding contract between you and Octet Logic OPC Private Limited, a company incorporated under the Companies Act, 2013, having its registered office in Hyderabad, Telangana, India (referred to in these Terms as “Octet Logic”, “we”, “us”, or “our”).
They govern your access to and use of GSTFiler — the software-as-a-service platform available at
www.gstfiler.com,app.gstfiler.com, and any associated subdomains, applications, application programming interfaces (APIs), and command-line tools we make available (collectively, the “Service”).By creating an account, signing in, or otherwise accessing the Service, you confirm that you have read and accept these Terms, our Privacy Policy and our Data Policy, each of which is incorporated by reference. If you are accepting these Terms on behalf of a business or other legal person, you confirm that you are authorised to bind that entity, and references to “you” include that entity.
If you do not agree, do not use the Service.
02The Service
GSTFiler is a Goods and Services Tax (GST) compliance platform built for businesses and tax consultants in India. The Service is intended to help you:
- prepare, validate and file GSTR-1, GSTR-3B and other GST returns;
- reconcile your books of account with GSTR-2A and GSTR-2B data fetched from the Goods and Services Tax Network (GSTN);
- triage Invoice Management System (IMS) actions, generate e-invoices, e-way bills, and other related artefacts;
- maintain workpapers, audit trails, and a calendar of statutory due dates.
The Service connects to GSTN through a NIC-approved GST Suvidha Provider (GSP) channel. The underlying tax law, return formats, validations, due dates, rates, and portal availability are set by the GSTN and the Government of India and are outside our control. The Service is software that helps you comply with that law — it is not a substitute for professional tax or legal advice.
03Who can use the Service
You may use the Service only if all of the following are true:
- you are at least 18 years of age and have the legal capacity to enter into a binding contract under Indian law;
- you are not barred from receiving services under the laws of India or any other applicable jurisdiction;
- any business you represent (a proprietorship, partnership, LLP, company, HUF, trust, society, or other entity) is duly registered or constituted, and you are an authorised representative of that business;
- any GST Identification Number (GSTIN) you add to the Service belongs to a business you own, employ you, or have a written engagement (such as a tax-consultancy engagement letter or board resolution) authorising you to act for.
We may refuse, suspend or terminate accounts that, in our reasonable judgement, do not meet these eligibility criteria.
04Your account, password and credentials
To use the Service you must create an account using a valid email address and a password, or sign in using a supported single-sign-on (SSO) provider where available. We may require email verification using a one-time password (OTP) before activating your account.
You are responsible for keeping your sign-in credentials secret, for choosing a strong password, and for all activity that takes place under your account. If you suspect unauthorised access, you must notify us at support@octetlogictech.com without delay so we can take appropriate action (such as forcing a session reset). We are not liable for losses arising from your failure to keep credentials confidential.
The Service enforces a single active session per user — signing in elsewhere will sign you out of earlier sessions. This is a security feature; it is not a basis for sharing one account across multiple individuals. Each human user must have their own account.
Workspaces with multiple team members are governed by the role-based access controls (RBAC) you configure. The workspace Owner is responsible for assigning, reviewing and revoking access for their team and for any acts or omissions of users they have invited.
05Filing through GSTN and use of EVC OTPs
When you choose to file a return through the Service, we transmit the return data to the GSTN through our GSP channel. The GSTN authenticates the filing using either a Digital Signature Certificate (DSC) or an Electronic Verification Code (EVC) one-time password sent to the registered mobile number of an authorised signatory.
By initiating a filing, you confirm that:
- you have reviewed the return and the underlying data, and the contents are true and correct to the best of your knowledge;
- the authorised signatory whose EVC OTP is used has read and approved the return;
- you alone are responsible for entering the OTP — we do not see or store your OTP after it is forwarded to the GSTN;
- once filed at the GSTN, a return cannot be cancelled or rolled back by us. Any rectification must be made through subsequent returns in accordance with the CGST Act, 2017 and rules made thereunder.
Network errors, GSTN downtime, NIC throttling, GSP rate-limits, last-day congestion and similar events are inherent to filing on a government portal. We do not guarantee that any specific return will be successfully filed by any specific deadline. You remain responsible for filing on time and we recommend you do not wait until the final hours of a due date.
06Your books and data — ownership
As between you and us, you own all data you upload, enter or generate in the Service — including your books of account, invoices, purchase registers, GSTIN registrations, return drafts, workpapers, comments and attachments (collectively, “Customer Data”).
You grant us a limited, worldwide, royalty-free, non-exclusive licence to host, copy, transmit, process and display Customer Data, solely to the extent necessary to operate the Service, file returns on your behalf, provide support, back up your data, and comply with law. We do not sell Customer Data and we do not use Customer Data to train artificial-intelligence models offered to other customers.
Detailed terms about residency, retention, access, sub-processors, breach notification and customer export / deletion are set out in our Data Policy.
07Your responsibilities
You agree that you will:
- provide accurate, current and complete information when you sign up, and keep it up to date;
- maintain your books of account in accordance with the Companies Act, 2013, the Income-tax Act, 1961, the CGST Act, 2017 and other applicable laws — the Service helps with compliance but does not replace your statutory record-keeping obligations;
- review any return, reconciliation, journal or report generated by the Service before you act on it or file it;
- obtain and maintain any consents required from your customers, vendors, employees and other data subjects whose personal data you process inside the Service;
- pay any taxes, interest, penalties, late fees, demands or assessments arising under tax law — these are between you and the tax authorities;
- comply with our Acceptable Use rules below.
08Acceptable use
You must not use the Service to:
- break any applicable law — including tax, anti-money-laundering, foreign-exchange, sanctions, competition, intellectual-property or privacy law;
- file or attempt to file returns on behalf of a GSTIN you are not authorised to represent;
- impersonate any person, falsify a digital signature, or use someone else’s OTP without their express, contemporaneous consent;
- upload viruses, malware, worms, time-bombs or any code intended to disrupt, damage or gain unauthorised access to the Service or other systems;
- interfere with the Service’s operation, probe its security, attempt to bypass authentication, rate-limits, or access controls (responsible-disclosure submissions to support@octetlogictech.com are welcome);
- reverse-engineer, decompile or disassemble any part of the Service, except to the extent the law expressly permits;
- scrape, mirror, frame or otherwise systematically download the Service’s content (including the HSN/SAC catalog, FAQ, or marketing copy);
- use the Service in any way that could damage Octet Logic’s reputation, brand or business.
We may suspend access immediately, without notice, if we reasonably believe you are in breach of this clause, if a regulator instructs us to, or if your use poses a security or stability risk to other customers.
09Plans, billing and renewal
We offer free, trial and paid plans. The features and limits of each plan are described on www.gstfiler.com/pricing and may change from time to time. Plan-specific terms (number of GSTINs, return volume, AMC inclusions, support response times) are part of these Terms.
Paid plans are billed in Indian Rupees (INR) and shown exclusive of GST unless stated otherwise. Applicable GST is added to your invoice at the rate in force on the invoice date. Subscriptions are billed monthly or annually as you select at checkout.
Unless we tell you otherwise at sign-up, paid subscriptions do not auto-renew; we will notify you before the end of your billing period and you may choose to renew. If you do not renew, your account moves to a read-only state at the end of the period and is subject to the deletion timelines in our Data Policy.
Payments are processed by third-party payment gateways. We do not store your full card number, CVV, UPI PIN or net-banking password — those remain with the gateway and your issuing bank.
10Free trials and refunds
Where a free trial is offered, it is limited to the duration shown at sign-up and to one trial per GSTIN / entity. Trial features may be restricted compared with the paid plan. We may end or shorten any trial at any time.
Subscriptions, set-up fees, training fees and one-time-implementation fees are non-refundable once paid. The narrow exceptions (duplicate charges and verified technical failure), the time-limit for raising a refund request, and the process for processing approved refunds are set out in our Refund Policy, which forms part of these Terms.
11Suspension and termination
You may terminate your subscription at any time by writing to support@octetlogictech.com or by following the in-app cancellation flow if available. Termination takes effect at the end of the then-current billing period; no pro-rata refund is owed for the unused portion.
We may suspend or terminate your account, in whole or in part, with or without notice, if:
- you breach these Terms and (where the breach is curable) you do not cure it within seven (7) days of being asked;
- you are 15 days or more overdue on a payment;
- your use poses a security, legal, regulatory or stability risk;
- we are required to do so by a competent authority, court order or applicable law;
- you become insolvent, file for bankruptcy, enter liquidation or otherwise cease ordinary operations.
Termination does not extinguish any payment obligation that accrued before termination, or any clause of these Terms that by its nature should survive (including clauses on intellectual property, disclaimers, limitation of liability, indemnity, governing law and dispute resolution).
12Intellectual property
The Service, its codebase, designs, branding, the GSTFiler name and wordmark, the Octet Logic name and wordmark, all documentation, the HSN/SAC catalog as compiled and presented by us, and all other materials we provide are owned by Octet Logic or our licensors. They are protected by Indian and international copyright, trademark and other intellectual-property laws.
Subject to your compliance with these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to access and use the Service for your internal business purposes for the duration of your subscription. No other rights are granted by implication, estoppel or otherwise.
If you give us feedback, suggestions or feature requests (“Feedback”), you agree we may use it without restriction and without owing you anything in return. We are not obliged to keep Feedback confidential.
13Third-party services
The Service interoperates with services run by third parties — including the GSTN, the NIC, our GSP partner, payment gateways, email and SMS providers, cloud infrastructure providers, and (if you enable them) analytics, e-invoice and e-way-bill services. These services are governed by their own terms and privacy policies. We are not responsible for their availability, accuracy or behaviour, but we will use reasonable efforts to choose reliable partners and to inform you of material changes.
A current list of the sub-processors we use to operate the Service is set out in our Data Policy.
14Disclaimers
The Service is provided “as is” and “as available”. To the maximum extent permitted by law, we disclaim all warranties, conditions and representations of any kind, whether express, implied or statutory — including any warranty of merchantability, fitness for a particular purpose, accuracy, non-infringement, or that the Service will be uninterrupted, secure or error-free.
Nothing in the Service constitutes tax, legal, accounting, audit or financial advice. Any opinions, classifications (including HSN/SAC suggestions), rate mappings, ITC eligibility hints or calculator results are informational and must be independently verified by you and, where appropriate, by a qualified professional before you act on them.
We do not warrant that the GSTN, NIC portal, or any third-party tax-authority system will accept any particular return, e-invoice, e-way-bill or other artefact, nor that any of those systems will be available on any particular date.
15Limitation of liability
To the maximum extent permitted by law, Octet Logic is not liable to you, your business, your team members, your customers, your vendors, or any other person for any loss, damage, cost or expense arising out of or in connection with these Terms or the Service. This includes, without limitation:
- any indirect, incidental, special, consequential, exemplary or punitive damages;
- any loss of profit, revenue, goodwill, reputation, anticipated savings, business opportunity, contracts or data;
- any tax, interest, late fee, penalty, demand, assessment or notice issued by any tax authority;
- any loss arising from delay, downtime, error, throttling, validation failure, or refusal at the GSTN, the NIC portal, our GSP partner, any payment gateway, or any other third-party system;
- any loss arising from the Service being unavailable, slow, or failing to perform on any particular date — including on or near a statutory due date;
- any loss arising from a return, e-invoice or e-way bill prepared or filed through the Service.
The above applies even if Octet Logic has been advised of the possibility of such loss, and whether the claim is framed in contract, tort, statute, equity or otherwise.
You agree that you will not claim, and will not seek reimbursement, indemnity or set-off from Octet Logic for any such loss or damage. You remain solely responsible for your own books, your own returns and your own tax positions, and for any tax, interest, penalty or other consequence that arises under tax law — whether or not the Service was used to prepare or file the underlying record.
Nothing in this clause limits or excludes any liability that cannot be limited or excluded under applicable law — including liability for fraud, gross negligence, wilful misconduct, or for death or personal injury caused by negligence. Where the law caps but does not allow exclusion, our liability is limited to the smallest amount permitted by law.
16Indemnity
You agree to defend, indemnify and hold harmless Octet Logic, its affiliates and their respective officers, directors, employees and agents from and against any claim, demand, loss, damage, cost or expense (including reasonable legal fees) arising out of or in connection with:
- your breach of these Terms, the Privacy Policy, the Data Policy, or applicable law;
- any return, e-invoice or other artefact filed by you or on your behalf through the Service;
- any Customer Data you upload, including any claim by a third party that such data infringes their rights or breaches their privacy;
- your acts or omissions and those of any user you have invited to your workspace.
We will give you prompt notice of any claim covered by this clause and reasonable cooperation in defending it. You may not settle any claim in a way that imposes an obligation on us without our prior written consent.
17Changes to the Service and these Terms
We are continuously improving the Service and may add, change or remove features, plans or prices at any time. Where a change materially reduces functionality on your paid plan during a billing period, we will, on request, refund you the unused portion of the relevant fees on a pro-rata basis.
We may amend these Terms by posting a revised version at
www.gstfiler.com/termsand updating the Effective Date and Version number at the top. Material changes will also be notified to you by email or in-app banner at least 15 days before they take effect. Your continued use of the Service after a change takes effect constitutes your acceptance of the revised Terms; if you do not agree, you must stop using the Service and may terminate as described in clause 11.18Notices and communications
We may send notices to you by email to the address registered with your account, by message inside the Service, by SMS to the mobile number you provide, or by posting on
www.gstfiler.com. Notices are deemed received when sent (for email and in-app) or 48 hours after dispatch (for SMS).You must send legal notices to support@octetlogictech.com with a copy by registered post to the registered office of Octet Logic OPC Private Limited, Hyderabad, Telangana, India.
19Governing law, jurisdiction and dispute resolution
These Terms, and any non-contractual obligations arising out of or in connection with them, are governed by the laws of the Republic of India, without reference to its conflict-of-laws principles.
Subject to the next paragraph, the courts at Hyderabad, Telangana have exclusive jurisdiction over any dispute arising out of or in connection with these Terms or the Service.
Before either party commences court proceedings, the parties will attempt in good faith to resolve the dispute by senior-management discussion within 30 days of written notice of the dispute. If the dispute remains unresolved at the end of that period, either party may refer the matter to arbitration by a sole arbitrator under the Arbitration and Conciliation Act, 1996. The seat and venue of arbitration shall be Hyderabad, Telangana, and the language shall be English. Nothing in this clause prevents a party from seeking interim or injunctive relief from a court.
20General
Entire agreement.
These Terms, together with the Privacy Policy, the Data Policy, your order form, any plan-specific schedule, and any addenda we sign with you, are the entire agreement between you and us about the Service and supersede any earlier agreement on the same subject.
Severability.
If any clause is held to be invalid or unenforceable, the rest of these Terms continue in effect, and the invalid clause is modified to the minimum extent necessary to make it enforceable.
No waiver.
A failure or delay by either party in exercising a right under these Terms is not a waiver of that right.
Assignment.
You may not assign these Terms or your account without our prior written consent. We may assign these Terms to an affiliate, or in connection with a merger, acquisition, financing or sale of all or substantially all of our business or assets, on notice to you.
Force majeure.
Neither party is liable for failure or delay caused by events beyond its reasonable control — including acts of God, government action, war, riots, fire, flood, earthquake, pandemic, internet outage, GSTN/NIC downtime, or denial-of-service attack.
Relationship.
We are independent contractors. Nothing in these Terms creates a partnership, joint venture, agency, fiduciary or employment relationship between you and us.
