Construction

Construction software fails because the estimate, the purchase orders, the site progress and the billing all live in different spreadsheets. We close the loop. We build estimating based on the BOQ, controlled buying, RA billing tied to site measurements, labour attendance, and RERA and drawing control that stand up in a dispute.

Construction software that closes the loop

From the BOQ to buying, to what was built, to what was billed. This is the estimate-versus-actual tool your project managers open first.

The real problem

The fourteen-percent margin was actually four.

Nobody discovers that on purpose. It happens because the estimate is in one spreadsheet, the purchase orders in another, site progress in a WhatsApp group, attendance in a register and billing in a third sheet. Nobody matches them up until the project is three months in. By then the extra material is already on site, the rates that moved away from the BOQ are already paid, the RA bills are six weeks behind the work, and the margin has quietly gone. None of this is a scheduling problem. It is a loop that never closed between what was estimated, bought, built and billed. We close that loop. It starts by making the BOQ the base that everything else is checked against.

Talk about your projects
Week 3
Overrun is visible

Estimate-versus-actual difference for each line item, while a cost overrun can still be managed and not regretted at handover.

3-way
Procurement match

PO, GRN and invoice are matched before a payment goes out. So material cannot be paid for before the order is approved and received.

Offline
Site capture

Progress, material use and geotagged photos are saved with no signal and sent later, with the time they were taken kept.

1day
RERA quarterly filing

A report you run from real site data, not two weeks spent working out what happened from a WhatsApp group.

Where construction platforms actually break

Construction software fails for a reason that has nothing to do with construction. It fails because the estimate lives in one spreadsheet, the purchase orders in another, site progress in a WhatsApp group, labour attendance in a register, and billing in a third spreadsheet — and by the time anyone matches them up, the project is three months in and a margin that looked like fourteen percent is actually four. The job of the software is to close the loop between what was estimated, what was bought, what was built and what was billed, almost live.

The BOQ is the contract, and estimate-versus-actual is the whole game

A project is won on a bill of quantities and lost on the gap between that BOQ and what actually got spent. Every serious construction platform is, at its core, a tool that holds the estimated quantity and rate for every line item and then tracks actual use against it, material by material and activity by activity. So a cost overrun is visible in week three, while it can still be managed, and not at handover when it is simply a loss. We build the BOQ as the base, link buying and site use back to its line items, and make the estimate-versus-actual difference the number the project manager opens the software to see.

Procurement and RA billing are where the cash actually moves

Material is the largest cost on most projects and procurement is where money leaks. Indents are raised without checking the BOQ, purchase orders are placed without approval, material is received without a proper GRN, and rates move away from what was estimated. We build indent-to-PO-to-GRN as a controlled flow with approvals and three-way matching against the invoice. On the income side, running-account (RA) bills are how a contractor gets paid. They show measured quantities of work done, priced against the contract, with retention and deductions worked out correctly, and progress claims that match what the site actually recorded. A contractor whose RA bills are behind the work is paying for the client's project out of their own money.

Labour, site and the things that only exist on the ground

A construction site runs on labour that turns up daily, and attendance written in a paper muster is attendance nobody can trust or match against the wage bill. Biometric or face-recognition attendance at the site gate, tied to the contractor and the labour category, makes the wage bill easy to prove and the work output easy to measure. Daily progress reports, material use, safety incidents, and photographs with location and time from the site are saved on an app that works offline, because a construction site is one of the worst places for a network. They are sent when a signal returns. This is also where the data for every compliance duty starts.

RERA, drawings and the document control nobody budgets for

For real-estate development, RERA asks for quarterly progress reports based on what actually happened on site, and strict handling of collections in escrow. But the quieter risk on any project is drawing and document control. A site team building from an old version of a drawing means a rework bill and a dispute waiting to happen. We build drawing registers with version control, transmittals with receipt confirmation, RFIs and their replies, and an approval trail. So the version on site is the current one, and when a claim or an arbitration comes, the document history is a real record and not a guess.

Modules

What we build into a construction platform.

BOQ & estimating

The bill of quantities as the base. It holds the estimated quantity and rate for each line item, and actual use is tracked against every one.

Procurement

Indent to PO to GRN with approval limits and three-way matching, rate contracts, and every purchase linked back to a BOQ line.

RA & progress billing

Bills raised from site measurements, priced to the contract, with retention, advance recovery and price rise worked out correctly.

Labour & attendance

Biometric or face-recognition attendance at the gate, tied to contractor and category, so the wage bill is easy to prove.

Site management app

Daily progress, material use, safety incidents and geotagged photos. It works offline first, because a site has no signal.

Drawing & document control

Drawing registers with version control, transmittals with receipt confirmation, RFIs and an approval trail that stands up in a dispute.

RERA disclosure

Milestone progress against plan, geotagged photographs and collections that follow escrow rules. The quarterly filing becomes a simple report.

Planning & scheduling

Activity plans, links between tasks and progress against schedule, so a late milestone is a warning and not a surprise at review.

Cost control & finance

Project P&L from committed and actual cost, subcontractor bills, GST, and a Tally or ERP handover that finance can trust.

Cash flow

RA bills that lag the work are a loan to your client.

The fastest way to sink a profitable project is to let the running-account bills fall behind the work. Every week that finished, measured work is not billed is a week the contractor is paying for the client's project out of their own pocket. On a large project that gap runs to crores.

We tie RA billing to the site measurements, so a bill is raised from recorded progress and not rebuilt from memory. Retention, mobilisation advance recovery, price rise and legal deductions are worked out against the contract and not by hand. And because the bill links back to the BOQ line items and the actual use, the margin on the project is visible as it is billed, not found out too late at final account.

India, specifically

The rules and realities you build against.

  • RERA

    Quarterly progress reports from real site data, strict handling of the restricted part of collections in escrow, and the registered project number on advertising.

  • GST on works contracts

    Works-contract GST, reverse charge on certain supplies, TDS under GST, and RA bills that match the returns and do not clash with them.

  • Labour compliance

    Attendance by contractor and category, wage records, and the papers that make a labour audit a simple question and not a rush.

  • Sites have no signal

    Progress, attendance and photos must work fully offline and send later, with the time they were taken on site kept.

  • Drawing revisions

    A team building from an old drawing means a rework bill. Version control and transmittals keep the current version on site.

  • Tally & ERP reality

    Finance runs on Tally or an ERP. A clean, matched handover of purchases, bills and payments is better than typing it all again.

How we ship it

The BOQ base first. Cost control comes from it.

  1. 01

    Walk a live site

    Weeks 1–2

    The stores, the gate, a progress meeting, a billing cycle. Every construction platform that gets dropped was designed far from the site.

  2. 02

    Build the BOQ engine

    Weeks 3–9

    The bill of quantities, estimate-versus-actual, and the difference view. Buying and billing both depend on this being right.

  3. 03

    Control the money

    Weeks 10–17

    Indent-to-PO-to-GRN with three-way matching, and RA billing tied to measurements. These are the two steps where cash actually moves.

  4. 04

    Take it to the ground

    Weeks 18–26

    The offline site app, attendance, drawing control and RERA reports. This is where the compliance data finally starts, clean and correct.

The stack

What a construction platform is built on.

Tough where the site needs it, controlled where the money moves, and honest about the books that finance already keeps.

The metrics that matter

What a project director actually watches.

Not a Gantt chart nobody updates. These are the numbers that decide whether a project makes money. A platform that cannot show them without a data export is not finished.

Talk to us
Cost
Variance to budget

Committed and actual cost against the BOQ, for each line item, live. This is the number that decides the project margin.

WIP
Work billed vs done

The gap between finished work and RA bills raised. Every rupee of it is your money lent to the client.

GRN
Unmatched receipts

Material received without a matching PO and invoice. This is the queue where buying leaks hide.

Plan
Progress vs schedule

Real progress against the planned milestone, for each activity, so a delay shows up weeks before the review.

Do you know your project margin today?

Not at final account but today, from committed and actual cost against the BOQ. If it lives in five spreadsheets that are matched up once a quarter, the margin is a surprise waiting to happen. Give us twenty minutes and we will show you what closing the loop changes.

FAQ

The questions you were going to ask on the call.

Because a project is won on a bill of quantities and lost on the gap between it and what actually got spent. The BOQ holds the estimated quantity and rate for every line item. The platform tracks actual use against it, material by material and activity by activity. That makes a cost overrun visible in week three, while it can still be managed, and not at handover when it is simply a loss. We make the estimate-versus-actual difference the number a project manager opens the software to see, and link buying and site use back to the BOQ line items.

Material is the largest cost and procurement is where money leaks. Indents are raised without checking the BOQ, POs are placed without approval, material is received without a proper GRN, and rates move away from the estimate. We build indent-to-PO-to-GRN as a controlled flow with approval limits and three-way matching against the supplier invoice. So a payment cannot go out before the order is approved and the delivery is received. Rate contracts and vendor performance are tracked, and every purchase links back to the BOQ line it was meant for.

Yes, and this is where contractors most often pay for the client out of their own pocket. Running-account bills are raised from actual site measurements, priced against the contract, with retention, mobilisation-advance recovery, price rise and legal deductions worked out correctly and not by hand. Because each bill links back to the BOQ and to recorded use, project margin is visible as it is billed and not found at final account. A bill that is behind the work is your money lent to the client with no interest.

It has to, because a construction site is one of the worst places for a network. Daily progress reports, material use, safety incidents, and photographs with location and time are saved offline and sent when a signal returns. The time they were taken is kept, not the time they were sent. Biometric or face-recognition attendance at the gate, tied to the contractor and labour category, makes the wage bill easy to prove and work output easy to measure. This is also where the raw data for your compliance duties starts.

For real-estate development, quarterly project-progress reports made from what actually happened on site, strict handling of the restricted part of collections in escrow, and the registered project number on advertising. The trap is that the report must come from real site data, which usually lives in an engineer's head and a WhatsApp group. Our site app saves milestone progress against plan with geotagged photographs, and the collections ledger understands escrow. So the quarterly filing becomes a report you run, and not two weeks of worried guesswork.

A working core — BOQ and estimating, procurement, RA billing and the site app with attendance — is typically 18 to 26 weeks from around ₹24,00,000. We build the BOQ base and the estimate-versus-actual tool first, because buying, billing and cost control all come from it. Then we build the site app, then RERA and document control. You are running a live project through it long before the last module is ready.
