Terms of service

These terms are an agreement between TATHA VASTU PRIVATE LIMITED (CIN U68200MH2026PTC466986, "Tatha Vastu", "we") and the organisation that signs up ("the customer", "you"). They take effect on 1 November 2026.

The service

Tatha Vastu provides software to record site measurements against BOQ items, generate RA bill packages, track deviations and recoveries, share bills with the client's engineer for checking, and sync certified bills to accounting tools. The service includes the web app, the site app and the client bill room, as described on our pricing page for each plan.

What Tatha Vastu does not do

• Tatha Vastu does not certify bills. Certification remains with the client's engineer-in-charge or the PMC appointed by the client.
• Tatha Vastu does not replace the engineer-in-charge's official measurement book where your contract requires one.
• Tatha Vastu does not file GST or TDS returns for you.
• Tatha Vastu does not give tax, legal or contractual advice. Recoveries and taxes are computed at the rates and rules you configure for each work order, and you are responsible for checking that they match your contract and current law.

Accounts and users

You are responsible for the people you invite, the roles you give them and the work orders they can see. Keep sign-in details private and tell us at once if you suspect someone else is using an account. Client and PMC users invited to a bill room use it free of charge and only for the bills shared with them.

Trial, plans and payment

A new customer can use Tatha Vastu free for 14 days on one live work order. At the end of the trial, the service continues only if you choose a plan. Fees are as shown on the pricing page or in a written order form, are exclusive of GST, and are payable in advance for the billing period chosen. A live work order is one with a bill in progress during the billing period; closed work orders move to a read-only archive at no charge.

We may change prices for a renewal term by telling you at least 30 days before it starts. Refunds follow our refund policy.

Your data

Everything you put into Tatha Vastu remains yours: BOQs, measurements, photos, bills, comments and certifications. You give us permission to host, process and display it only to provide the service to you and the users you authorise. We process personal data inside your content as your Data Processor under our data processing agreement, which forms part of these terms.

You can export your bills, measurement sheets and registers in Excel and PDF at any time. After your subscription ends, your account stays available read-only for 60 days so you can export everything. After that, we erase your content, except copies the law requires us to keep.

Acceptable use

• Do not upload content you have no right to use, or content that is unlawful.
• Do not use the service to make or present a bill you know to be false.
• Do not try to reach data you have not been given access to, or test our security without following our responsible disclosure terms on the security page.
• Do not resell the service or copy it to build a competing product.

We may suspend access that breaks these rules or puts other customers at risk, and we will tell you why, unless the law prevents us.

Availability and support

We work to keep Tatha Vastu available at all times and post the current state on our status page. Planned maintenance is announced in advance and scheduled outside Indian working hours where possible. Support requests are answered within one working day.

Intellectual property

We own the software, the bill formats we build into it and our documentation. A custom format built from your client's bill belongs to you as far as it reflects your client's document, and we may reuse the general method but not your data.

Warranties and liability

We will provide the service with reasonable skill and care. Apart from that, the service is provided as it is, and we do not promise that a client will certify or pay any bill. To the extent the law allows, neither party is liable for indirect or consequential loss, and our total liability in any 12 months is limited to the fees you paid us in those 12 months. Nothing limits liability that cannot be limited under Indian law.

Ending the agreement

You can cancel at any time; the cancellation takes effect at the end of the paid period. Either party may end the agreement at once if the other materially breaks these terms and does not fix the breach within 30 days of written notice.

Law and courts

These terms are governed by the laws of India, including the Information Technology Act, 2000. The courts at Mumbai, Maharashtra have exclusive jurisdiction over any dispute arising from them.

Notices to us go to TATHA VASTU PRIVATE LIMITED, 31, Poddar Chamber, S A Brelvi Road, Horniman Circle, Mumbai, Maharashtra 400001, India, or through the contact form. We send notices to the email address of the account owner.
