Custom Software Development for Construction Companies

Stacklyn builds enterprise construction software for contractors, infrastructure developers, and construction MNCs. We deliver project controls platforms, digital site progress tracking, subcontractor and BOQ billing systems, QA/QC and snag list apps, and material and plant tracking software built for the realities of multi-site construction delivery.

Industry Background

Software Challenges in the Construction Sector

Construction runs on thin margins, long supply chains, and thousands of daily decisions taken at site level — yet most contractors still coordinate through WhatsApp groups, Excel trackers, and PDF drawings. Large contractors run Primavera P6 or MS Project at the planning layer and SAP or Tally at the finance layer, but the site execution layer between them is almost always a spreadsheet. That gap is where cost overruns, rework, delayed variations, and disputed claims are created. Purpose-built execution software closes it by capturing progress, quality, labour, and material data at source.

Industry Pain Points

Problems We Solve for Construction Companies

Site Progress Trapped in Excel

Daily progress reports compiled manually from site engineers, reaching management days late and too aggregated to act on.

Drawing Version Chaos

Site teams working from superseded drawings and revisions, causing rework that is only discovered at inspection stage.

Subcontractor Billing Disputes

Manual measurement books and work-done certification creating disputes, delayed RA bills, and unrecoverable claims.

Material & Equipment Leakage

No real-time visibility of material consumption against BOQ, idle plant hire, and untracked movement of equipment between sites.

QA/QC and Snag Backlogs

Paper-based inspection checklists and snag lists that never close out, holding up handover and retention release.

Labour Productivity Blind Spots

No reliable data on manpower deployed versus output achieved per activity, making productivity claims impossible to defend.

What We Build

Software Solutions for Construction Companies

01

Construction Project Controls Platform

Unified dashboard for planned versus actual progress, S-curves, cost-to-complete, and variance analysis. Integrates with Primavera P6 and MS Project schedules while capturing execution data from site.

02

Digital Daily Progress Reporting (DPR)

Mobile-first DPR app for site engineers: activity-wise progress, manpower deployed, plant utilised, weather, and hold-ups — captured offline at site and rolled up into management dashboards automatically.

03

BOQ, Measurement & Subcontractor Billing

Digital measurement book, work-done certification workflows, RA bill generation, deduction and retention handling, and subcontractor billing portals that shorten certification cycles from weeks to days.

04

QA/QC, Snagging & Handover App

Configurable inspection and test plans (ITP), digital checklists, photo-evidenced snag capture with drawing pinning, NCR workflows, and handover dossier generation for client acceptance.

05

Drawing & Document Control System

Controlled revision management for drawings, RFIs, transmittals, and specifications with automatic superseding, distribution matrices, and mobile access to the current revision at site.

06

Material, Store & Inventory Management

GRN-to-consumption tracking against BOQ, indent and issue workflows, multi-store stock visibility, reconciliation reports, and wastage analysis integrated with procurement and ERP systems.

07

Plant, Equipment & Hire Management

Equipment register, log sheet capture, utilisation and idle-hour analysis, hire cost tracking, preventive maintenance scheduling, and inter-site transfer workflows for owned and hired plant.

08

Site Safety & Permit-to-Work System

Digital permit-to-work issue and closure, toolbox talk records, safety observation rounds, incident and near-miss reporting, and workforce induction tracking across all active project sites.

Why Stacklyn

Why Construction Companies Choose Stacklyn

We Speak Construction, Not Generic SaaS

BOQ, RA bills, measurement books, ITPs, NCRs, retention, and variation orders are the vocabulary we design around — not an afterthought bolted onto a generic project tool.

Offline-First Site Apps

Basements, tunnels, and remote alignments have no signal. Our site apps capture data offline and sync automatically when connectivity returns, with conflict-safe merging.

Integrates With What You Already Run

We connect to Primavera P6, MS Project, SAP, Tally, and existing ERP investments rather than asking you to rip out working systems.

Built for Multi-Project, Multi-Entity Groups

Role-based access by project, entity, and region, with consolidated group-level reporting for management and board review.

Photo & Evidence-Led Workflows

Every progress claim, snag, and inspection carries timestamped, geotagged photo evidence — the difference between a claim that is paid and one that is disputed.

Rapid Pilot, Then Scale

We start with one live project as a pilot in 8-12 weeks, prove value against real site data, then roll out across the portfolio.
