Interior Fit-Out Project Management System Web App

The Interior Fit-Out Project Management System Web App runs a commercial fit-out business from first enquiry to final handover in one browser application: 27 modules, 7 editable roles, 30 ready-made reports and a database of 32 tables seeded with 10,708 rows of working demo data, so every screen is populated the moment you sign in. It is built on Google Apps Script and stores everything in a Google Sheet in your own Drive.

Quotations and BOQ, work packages with weighted progress, site tasks, snags and punch lists, inspections, handover and DLP, subcontractors, materials and stock, purchase orders, goods receipt, labour, timesheets, milestone invoices with retention, payments and expenses all live in the same interior fit-out project management system, so the numbers on the dashboard always agree with the records underneath. Think of it as interior contractor management software, a snag list and BOQ tracker and a Google Apps Script project management web app in one download.

🔑 Key Features of the Interior Fit-Out Project Management System

📊 Live project dashboard. Nine KPI cards show active projects, contract value in hand, invoiced and collected over 12 months, outstanding receivables, gross margin, open snags, overdue site tasks and materials to reorder. Below them sit Billing and Collection by Month, Project Mix by Status, Largest Live Contracts, Package Progress by Trade, Open Snags by Trade and a “What needs attention” list.

📐 Quotations and BOQ. Price each enquiry as a bill of quantities with area in sq ft, net value and value with GST, then track it through Draft, Sent, Under Review, Won, Lost or Expired. The page reports quoted value, won value, win rate and quotations awaiting a decision.

🧱 Weighted progress, not guesswork. Each project is split into trade work packages (civil, gypsum and ceiling, flooring, joinery, glazing, painting, electrical, HVAC, fire fighting, plumbing) with a budget and a weight %, so project progress rolls up from real package and task progress.

🔧 Snags, inspections and handover. Raise snags by location, trade and severity, assign them to a subcontractor with a target date, and close them. Record inspections, then log handover with the defect liability period (DLP) start and end dates and any snags carried over.

🚚 Procurement and site cost. Materials with reorder levels, stock movements, purchase orders to suppliers and subcontractors, goods receipt notes with partial receipts, a labour register and weekly timesheets feed cost to date on every project.

💰 Milestone invoicing with retention. Invoices carry invoice value, retention, net payable, amount received and due date, and the Payments and Expenses modules complete the money trail. Receivables, overdue amounts and retention held show at the top of the page.

📑 30 management reports. Project Profitability, BOQ vs Actual Cost, Two Week Look Ahead, Subcontractor Performance, Snag Register and Ageing, Retention Held, Cash Flow Summary and 23 more, each with date, project and client filters, print and CSV export.

🔐 Roles, audit and housekeeping. Seven editable roles control the sidebar, every change is written to an Audit Log, and Settings, List Management and Database Archive let you rebrand the system, edit dropdowns and move old records out of the live tables.

📦 What’s Inside the Interior Fit-Out Project Management System

Your ZIP download holds Code.cs.txt (the Apps Script server code), Index.txt (the complete interface) and the PDF user manual. The sidebar groups 27 modules into Overview, Commercial, Delivery, Supply Chain, Site Workforce, Finance, Records and Administration, plus a Help page. Ten of the screens are shown below.

📊 Interior Fit-Out Project Management System vs. Excel Tracker vs. Paid Construction Software

For fit-out contractors who want quotations, site delivery, procurement and billing in one system without a per-user subscription, this fit-out system sits in the sweet spot.

👥 Who This Template Is For, and Who It’s Not For

✅ This template is built for:

• Commercial interior fit-out contractors running 5 to 40 office, retail, hospitality, clinic or campus projects a year
• Turnkey interior firms that price a BOQ, manage trade subcontractors and bill by milestone with retention
• Project managers and quantity surveyors who need snag, handover and DLP records next to the money

❌ This template is NOT for:

• Teams that need Gantt charts, CPM scheduling or BIM model links, which this system does not include
• Firms that need statutory tax filing, e-invoicing or a link to their accounting software; invoices here are internal billing records
• Crews that must work offline on site; the app needs an internet connection and runs in the browser

💼 Real-World Use Cases

A fit-out contractor in Mumbai with 12 live office sites. The quantity surveyor prices every enquiry as a BOQ, the project managers watch package progress by trade, and the director signs in with the read-only Viewer role on Monday mornings to check contract value in hand, receivables and overdue site tasks.

A retail interiors firm rolling out store fit-outs. The procurement officer raises purchase orders against each store, site engineers record goods receipt and timesheets, and the BOQ vs Actual Cost report shows which stores are running over budget before the final account.

A hospitality fit-out specialist with long defect periods. Snags are assigned to subcontractors with target dates, handovers record the DLP end date, and the Retention Held report shows exactly how much money is still waiting on DLP release.

❓ Frequently Asked Questions

Can I try the Interior Fit-Out Project Management System before buying?

Yes. The live demo above runs the full system with fictional data. Sign in with any of the 10 demo accounts to see the dashboard, the modules each of the 7 roles can reach, and all 30 reports before you spend anything.

What do I need to run it?

A Google account. This web app runs on Google Apps Script and creates its own Google Sheet database in your Drive during setup. Users sign in with the user names you create, so they do not need their own Google accounts.

How long does setup take?

About 15 minutes. You paste two files into a new Apps Script project, deploy it as a web app and run setup once. Setup builds 32 tables and seeds demo data, and it resumes automatically if Google’s time limit interrupts it.

How does this compare to Procore or Buildertrend?

Those are subscription platforms with scheduling, mobile apps and integrations. This fit-out project management software is a one-time $39.99 purchase that covers quotations, packages, snags, procurement and billing on your own Google account, without Gantt scheduling, offline use or accounting integrations.

Can I change the currency, tax and print size?

Yes. The demo shows Indian Rupees and GST, but Settings lets you set the currency symbol, default GST %, retention %, credit days, company details and print size (3 inch, 4 inch or A4) used on quotations, orders and invoices.

Can I add more users or change what a role can see?

Yes. There is no per-user fee. Open Users & Roles to add users and reset passwords, pick a role and tick exactly the permissions it should hold, and the sidebar follows those permissions immediately.
