ERP for construction · interiors · HR · business

Every site, store and payslip on one record.

From the first enquiry to the handover certificate — sales pipeline, BOQs, purchase, site stores, finance and payroll share one set of numbers. The AI reads them and shows its working.

Free during early access · paid plans from 2027

The Tathyank site intelligence Signals screen: counts of critical, open, acknowledged and self-cleared signals, and a list of open signals — a flooring task slipping behind the joinery handover, a cost head over budget, a late delivery — each with the numbers that raised it.

02AI & workflow automation


AI that shows its working.

Say what happened on site. Tathyank changes every record it touches — and nothing is saved until you confirm it. Predictions list what they read; a person accepts them.

  • CMD

    One instruction, many records

    Type or speak once: tasks, payment requests and activity progress update together, each confirmed by you.

  • SI2

    Voice notes from site

    Supervisors talk; the note lands on the right activity.

  • SI3

    Drawing takeoff

    Quantities read off drawings into the BOQ for a person to review.

  • SI6

    Signals and predictions

    Delays, overruns and low stock flagged from your own numbers; predictions carry a confidence.

  • AUTO

    Approvals and escalation

    An approval matrix with amount bands, levels, delegation and SLA escalation.

Joinery is likely to start eleven days late, not six.

What it read: forecast finish · supplier lead times · two open finish approvals · the last four joinery starts. Accepting raises the work; it changes no plan by itself.

Everything on this page ships at launch.

03One record, end to end


From the first enquiry to the handover certificate.

A won deal becomes a project site; the BOQ drives purchase; receipts land in the site store; bills match the PO and the goods; the client signs off in the portal.

The Tathyank CRM forecast screen: the weighted pipeline by the month each deal is expected to close, against a monthly target, beside the pipeline by lead band, and the start of a table of open deals by stage with each stage’s probability and weighted value, all in rupees.

Sales pipeline, weighted

Every open deal times its stage probability, by the month it should close — against the target the partners set.

The Tathyank Site stores list: each site store and the central yard with its site, warehouse and bins, type, storekeeper, value on hand, capacity and status, a site with no store yet, and a closed store kept for its history.

Site stores and warehouses

Stock on hand and capacity for every site and the central yard.

Nothing retyped


A finish chosen once is never typed again.

Each record is made from the one before it, so a quantity, a rate or a vendor is entered once and carried through to the ledger.

04Why teams switch


More of the business, on the same numbers.

Project tools stop at the site. Tathyank carries on into the pipeline before it and the payroll behind it.

05Case study


Built with the first team that runs on it.

A turnkey interiors contractor fitting out corporate offices and bank branches, with offices in four Indian cities. They signed up on their own and sent a brief.

What they asked for

  • A stage-wise project tracker
  • A Measurement Book, with advance and billing trackers
  • Attendance, leave and payroll
  • Drawings, material lists and vendor lists

What was built from the brief

  • The Measurement Book, with check and approval
  • Advances and RA billing
  • The stage tracker, with a Gantt chart
  • Drawings with pinned comments, and finishes that push to the BOQ
  • The vendor and material chain, from purchase to the site store

What runs for them

  • Attendance, leave and payroll since August 2026
  • The AI HR assistant for their admin since September 2026
  • An office IP allowlist, checked on every request
  • Staff email sent in their own name
  • The construction modules, switched on in September 2026
