# Tathyank > Tathyank is an ERP for construction, interior design, HR and general business in India. Sales, BOQs, purchase, site stores, finance and payroll share one set of numbers, and payroll computes Indian statutory deductions from the same register that produced the payslip. ## Status - Everything described in this file is in the Tathyank launch release and is switched on per workspace. One module, inbox operations, is switched off. - AI is off by default in every workspace until the workspace switches it on. The assistant works with the asker’s own permissions, cannot delete a record, saves nothing until a person confirms it, and payroll has no AI. - Early access is free, by invitation, until paid plans start in 2027. No price list is published. ## Industry packs - [Construction](https://www.tathyank.com/construction): Tender to handover, on one set of numbers. BOQs drive purchase, receipts land in the site store, labour bills match the muster, and project finance shows budget, committed and actual for every cost head — across every site. - [Interior design](https://www.tathyank.com/interior-design): From moodboard to handover, without the WhatsApp chase. Finishes chosen on the moodboard become BOQ lines, the client approves in their portal, and site updates, payment requests and the handover certificate sit on the same project. - [HRMS](https://www.tathyank.com/hrms): Payroll that gets the statutory part right — live today. Attendance, leave and holidays feed a payroll that computes PF, ESI, professional tax by state slab, TDS under both regimes, gratuity and full-and-final — from the same register that produced the payslip. - [General business](https://www.tathyank.com/general-business): Sell, bill and stock across every brand you run. CRM pipeline, quotes to orders to invoices to payments, and stock across stores — for trading, services and multi-brand businesses. ## Indian statutory payroll - Attendance: Muster, shifts and regularisation. Biometric device sync from ZKTeco and eSSL. - Payroll and statutory: PF, ESI, PT by state slab, TDS under both regimes, gratuity, full-and-final. - Filing outputs: Bank advice, PF ECR, ESI return, PT and LWF challans, journal voucher, cost by centre and Form 16 Part B. - Registers by state: Muster roll, overtime and leave registers in Form 25, Form II, Form P and Form G, and a generic form elsewhere. ## Pages - [Tathyank — ERP for construction, interiors, HR and business](https://www.tathyank.com): From the first enquiry to the handover certificate — sales pipeline, BOQs, purchase, site stores, finance and payroll share one set of numbers. - [What does Tathyank mean? तथ्याङ्क — the figure that is true](https://www.tathyank.com/name): Tathyank (तथ्याङ्क, tathyāṅka) is Sanskrit: तथ्य (tathya) a fact, that which is so, and अङ्क (aṅka) a mark or figure.
