Construction ERP software in Coimbatore

Yes — LekhaPro's Construction pack runs a Coimbatore contractor's projects end to end: priced BOQs with rate analysis, critical-path schedules, and measurement books feeding RA bills whose waterfall — retention, advance recovery, LD, 194C TDS, GST — reconciles to the paise. The 1% labour cess on Coimbatore sites goes to Tamil Nadu Construction Workers Welfare Board (labour.tn.gov.in), a cost line the project accounts carry. Cloud edition, any browser.

The Coimbatore trade, honestly

Coimbatore’s construction trade grew up alongside its pump, motor and foundry industries, so industrial sheds, plant civil works and effluent infrastructure sit beside public contracts — smart-city streetscapes and lake restoration, Highways Department jobs, and the elevated corridor taking shape along Avinashi Road. Private industrial clients negotiate hard on milestones and back-to-back subcontract terms; government work follows SOR tendering, measurement books and running bills with retention. M-sand from district crushers softens one input cost, but steel and cement swings still travel straight into rate analysis and every RA bill’s escalation working.

What a Coimbatore contractor gets

  • Project portfolio with parties, document register and a health read
  • BOQ, schedule-of-rates library, rate analysis & variation orders
  • WBS, CPM critical path and float, baselines & 14-day look-ahead
  • Delay analysis against the saved baseline
  • Material indents → Procurement PR/PO/GRN with receipt progress
  • Labour, equipment-hour and site-expense capture into the core ledger
  • Measurement Book with a cumulative BOQ-quantity guard
  • RA billing waterfall — retention, advance recovery, LD, 194C TDS, GST
  • Running contractor statement that ties out every bill
  • Project costing and budget-vs-actual against the estimate
  • EVM — CPI/SPI, cost-to-complete, EAC, VAC and project profitability
  • Quality & safety — NCR/CAPA, snags, the HSE register, and a blocked-until-clear handover

Plans are ₹249, ₹449 and ₹2,499 a month — GST-inclusive totals on pricing. New to the terms? Place of supply decides the tax head on every invoice, and goods movements may need an e-way bill.

What it does not do — in Coimbatore or anywhere

  • · The Construction pack is Cloud-only — it runs in a browser, not in the offline Windows desktop edition, in Coimbatore or anywhere.
  • · It does not register your establishment with the BOCW board or file the cess — it carries the cess as a cost line; registration stays between you and the board.
  • · It is not a CAD, BIM or quantity-takeoff tool — BOQ quantities are entered against the schedule of rates, not derived from drawings.
  • · GST and 194C TDS are computed on the RA bill but not filed for you; submission stays with you or your CA.
  • · No office in Coimbatore — sales and support are online (email and WhatsApp) from an India-based team, with no local branch, reseller or on-site visit.
  • · No payroll, attendance or HR module — staff salaries and professional tax stay with your CA, in Tamil Nadu as everywhere.

Questions Coimbatore contractors ask

Does the Construction pack work for a Coimbatore contractor?

Yes. Projects carry a priced BOQ against a schedule-of-rates library with rate analysis and variation orders, a WBS with a full critical-path pass, and site execution — indents, labour logs, equipment hours, expenses — that posts into the core books rather than a second set. It is a Cloud pack, run from any browser, and nothing is city-locked.

Who collects the labour cess on Coimbatore sites?

Tamil Nadu Construction Workers Welfare Board (labour.tn.gov.in) (TN Labour Dept GO PDF — TN Construction Workers Welfare Board, Chennai, checked 2026-08-05) — the board that registers establishments and collects the 1% BOCW cess in Tamil Nadu. LekhaPro carries the cess as a cost line in the project accounts; registering with the board and depositing the cess stay between you and it.

How do measurement books become RA bills?

Each Measurement Book line records this-bill quantity against the BOQ ceiling and the cumulative already certified, and the RA generator refuses quantity beyond the ceiling — over-billing needs a variation order, not a keystroke. The bill then runs one waterfall: gross, less retention, less advance recovery, less LD, less 194C TDS, plus GST, to a net certified figure the running statement ties out on every bill.

How does GST work on a Coimbatore works contract?

The place of supply for works on immovable property is where the site stands — so a Coimbatore project answers to Tamil Nadu (code 33) regardless of where your head office sits, and the RA bill raises CGST + SGST or IGST accordingly on the core invoice path. Whether an out-of-state contractor needs a local registration is a question for your CA; the pack computes and posts either way.

Are retention and mobilisation advances tracked?

Yes, with server-side caps: retention stops accruing at the contract ceiling, advance recovery stops at the outstanding mobilisation balance, and the LD penalty is capped at its ceiling — each computed on the bill, not remembered in a spreadsheet. The running contractor statement asserts the waterfall identity across the whole bill series.

Can it tell me a project is slipping before the client does?

That is what the schedule and earned-value layer is for: saved baselines with delay analysis against them, a 14-day look-ahead, and PV/EV/AC producing CPI and SPI with cost-to-complete and estimate-at-completion. A CPI drifting below par on a Coimbatore job shows up in the numbers months before it shows up in a site meeting.

How do site materials and expenses reach the books?

Material indents approve into purchase requisitions that Procurement carries through PR → PO → GRN with receipt progress reported back; labour logs give cost per unit by work type; equipment logs are hours × rate plus fuel; and site expenses go draft → approve → post into the core expense ledger. There is no parallel site cashbook to reconcile later.

Can quality or safety issues block a handover?

Yes — deliberately. Inspections, material tests, NCRs with CAPA, a snag list and an HSE register run alongside execution, and handover stays blocked while snags or NCRs are open. Closing it stamps the warranty and flips the project into defect liability, which is the sequence a client's engineer expects to see.

What about e-way bills for material moving to site?

Within Tamil Nadu, an e-way bill applies above ₹1,00,000 (100 annexure goods exempt at any value) (Ntf No. 09/2018 Rc.46/2018/Taxation/A1 (31.05.2018) · ctd.tn.gov.in, checked 2026-08-05); inter-state movements follow the national ₹50,000 rule. LekhaPro generates the JSON from the underlying document either way.

How do we try it on a live Coimbatore project?

14 days free, no card. Load one real BOQ, enter last month's measurements and generate the RA bill — then put it beside the one your billing engineer produced, because the waterfall reconciling to the paise is the point. We sell and support online only, with no Coimbatore branch. Local context: Coimbatore’s construction trade grew up alongside its pump, motor and foundry industries, so industrial sheds, plant civil works and effluent infrastructure sit beside public contracts — smart-city streetscapes and lake restoration, Highways Department jobs, and the elevated corridor taking shape along Avinashi Road.
