In short

SimpleERP is ERP software for civil contractors and interior contractors in India. Quotations become orders and SAC-coded GST invoices, material is bought and moved between site warehouses, and payroll with advances, site expense claims and machinery depreciation post to one ledger.

A day in a contracting business

A contractor runs several sites at once, and the money leaks through material, labour and small cash spends that nobody writes down.

Morning at Arun Builders starts on the phone. The supervisor at the Velachery site needs forty more bags of cement, the interior team at an office fit-out in Guindy is short of plywood, and the client for a villa in Porur wants a revised quotation for the compound wall.

Material goes to whichever site shouts loudest. Surplus tiles sit at one site while another buys fresh. Supervisors pay for diesel, tea and a hired mixer from their own pockets and hand in a fistful of slips at month end. The mason who took an advance in June is still on a page in the accountant's notebook.

SimpleERP gives each site its own warehouse, so material is bought into it and moved out of it on record, and it ties the money to two documents: the quotation the client accepts, and the GST invoice with the right SAC code that you raise against it.

Sales

Quote the job once and bill it in stages

A quotation the client accepts converts into a sales order or an invoice without retyping, and a sales order can be invoiced in parts, so a large job can be billed stage by stage against what was agreed.

  • Revise a sent quotation into a new draft; the old one stays as it was sent.
  • Partial invoicing. The order tracks what has been billed and what is still open.
  • One customer per client, with a ship-to address per site that drives the place of supply.

GST billing

Invoices with the right SAC code for works

Set up your works and labour as service items with a SAC code and a rate, and supplied goods as products with an HSN code, and one invoice can carry both with the tax split worked out per line.

  • CGST and SGST or IGST from the place of supply of the site.
  • HSN or SAC on every line and a summary on the print.
  • Sales register by period and branch for your GSTR-1 check.

Purchase and inventory

Know what material is lying at each site

Make each site a warehouse, and every supplier bill receives cement, steel or plywood into the site it was delivered to, so stock on hand by site is a report, not a phone call.

  • Purchase orders to dealers with a deliver-to warehouse per site.
  • Stock transfers move surplus from one site to the next, at average cost.
  • Supplier bills and payables with an ageing of what you owe each dealer.
  • Stock adjustments with a reason for wastage found at a site count.

Expenses

Site spends recorded the day they happen

Supervisors file expense claims from their phone with a photo of each slip, a manager approves them, and the accountant reimburses, with every step posted to the books.

  • Claim lines with receipts for diesel, hire charges, food and travel.
  • Approve or reject with a reason; approved amounts can be trimmed.
  • Quick expenses paid from cash or bank, tagged to a branch when you use one per site.

Payroll and assets

Pay the crew and track the machinery

Monthly payroll reads attendance and salary structures, recovers advances through the payslip, and posts to the books, while the mixer, the scaffolding and the site vehicle depreciate every month in the asset register.

  • Advances paid to workers and recovered month by month.
  • Salary components such as Basic, allowances, PF and PT per employee.
  • Fixed assets with a custodian, maintenance records and monthly depreciation.

Ready on day one

What you don't have to set up

SimpleERP seeds the routine parts when you sign up, so your first day is about your sites and clients, not about configuring software.

  • A chart of accounts with inventory, payables, salaries and fixed asset accounts already mapped.
  • GST rates split into CGST, SGST and IGST, ready to pick on a product or a service.
  • Units such as bags, kilograms, metres and pieces, and numbering on the April to March year.
  • Asset categories such as Plant and machinery and Vehicles, with straight-line depreciation.
  • Seven ready-made roles, from Owner to Employee self-service, to copy and adjust for site supervisors.

One system

The modules that do this work

A supplier bill puts material into a site warehouse, an invoice writes the sale and the GST, and payroll, claims and depreciation post to the same ledger.

Honest limits

What SimpleERP does not do for contractors yet

We would rather you know now than find out in month two.

  • Project accounting or site-wise profit and loss. Use a warehouse per site for material and, where it helps, a branch per site so registers and expenses can be filtered by site.
  • Retention money or running account (RA) bills. Bill each stage as an invoice against the sales order, and record retention with your CA's advice.
  • Piece-rate or daily-wage payroll. Payroll is a monthly salary with components and advances.
  • E-way bill generation or e-invoice (IRN) through the government APIs.
  • Batch or serial number tracking for material. Stock is tracked by product and warehouse.

FAQ

Questions, answered

What GST rate applies to construction and interior works?

It depends on the kind of work and the client. Works contracts usually fall under SAC 9954, often at 18%, and goods supplied separately carry their own HSN code, such as 9403 for furniture. In SimpleERP you set the SAC or HSN code and rate on each item, and the invoice applies CGST and SGST or IGST from the place of supply. Rates change, so confirm the rate for your goods with your CA or the GST portal before you rely on it.

Can SimpleERP show profit and loss for each site?

No, there is no project accounting yet. Material per site is visible when each site is a warehouse, and if you set up a branch per site, invoices, expenses and registers can be filtered by that branch. A full site-wise profit and loss is not something it produces today.

Can I move leftover material from one site to another?

Yes. A stock transfer moves the quantity from one site warehouse to the other at weighted average cost, and both warehouses show the movement in their history.

We have about forty people across sites. Will it work for us?

Yes. Each person can have their own login with a role, supervisors can file expense claims and employees can check in from a phone browser, and payroll runs for everyone each month. There is no separate mobile app; it is a responsive web app.

We keep accounts in Tally and site records in Excel. How do we move?

Import your material list from a CSV file with opening stock per site warehouse, add your clients and dealers, and enter opening balances. Many contractors start with new invoices and supplier bills from the first day of a month and keep the old books for reference.
