The Interior Fit-Out Project Management System is a Google Apps Script web app with 27 modules, 7 editable roles and 30 ready-made reports. Setup builds a Google Sheet database of 32 tables and seeds it with 10,708 rows of demo data for a fictional contractor running 34 fit-out contracts, so every screen and report is populated the moment you sign in.
Commercial fit-out work is hard to track in spreadsheets because the money and the site move at different speeds. A BOQ is priced in one file, packages are let to subcontractors in another, snags live on a site engineer’s phone and retention sits in the accounts ledger. This interior fit-out project management system puts quotations, work packages, site tasks, snags, procurement, labour and milestone billing in one browser application on your own Google account, so the dashboard and the records always agree. It works as a snag list and BOQ tracker, a subcontractor and purchase order register and a Google Apps Script project management web app at the same time.

Key Features of the Interior Fit-Out Project Management System
- Nine-card live dashboard. Active projects, contract value in hand, invoiced and collected over 12 months, outstanding receivables, gross margin, open snags, overdue site tasks and materials at or below reorder level, with a “What needs attention” list that opens the module behind each alert.
- Quotations and BOQ with win rate. Every enquiry is priced as a bill of quantities with area, net value and value with GST, and the page tracks quoted value, won value, win rate and quotations awaiting a decision.
- Progress driven by site weightages. Trade work packages carry a budget and a weight %, so project progress rolls up from real package and task completion instead of a number someone typed in.
- Snag-to-handover control. Snags carry location, trade, severity, assignee and target date; handovers record the defect liability period and the snags carried over.
- Procurement and cost to date. Materials, stock movements, purchase orders, goods receipt notes, labour and timesheets feed the cost side of the Project Profitability report.
- Milestone billing with retention. Invoices hold invoice value, retention, net payable, received and due date, and Payments and Expenses complete the money trail.
- Seven editable roles and an audit log. Tick exactly which permissions a role holds and the sidebar follows them immediately; every create, edit and upload is written to the Audit Log.

Who Should Use This Template
Perfect for:
- Commercial interior fit-out contractors running office, retail, hospitality, clinic and campus projects
- Turnkey interior firms that price a BOQ, let trade packages to subcontractors and bill by milestone with retention
- Owners who want fit-out project management software they can edit, with no per-user subscription
Not a fit if:
- You need Gantt charts, critical-path scheduling or BIM links
- You need statutory tax filing, e-invoicing or an accounting-software integration
- Your crews must record work offline; the app needs an internet connection
Real-World Use Cases
An office fit-out contractor with a dozen live sites. The quantity surveyor prices every enquiry as a BOQ, project managers track package progress by trade, and the managing director signs in as a Viewer each Monday to check value in hand, receivables and overdue site tasks without being able to change a record.
A retail interiors firm rolling out stores. The procurement officer raises purchase orders per store, site engineers record goods receipt and timesheets, and the BOQ vs Actual Cost report flags stores drifting over budget before the final account is agreed.
A hospitality fit-out specialist. Snags are assigned to subcontractors with target dates, handovers record the DLP end date, and the Retention Held report shows how much money is still waiting on release.
Advantages of the Interior Fit-Out Project Management System
- One purchase, unlimited users. There are no seat fees, so site engineers, surveyors and accounts staff can all have their own login.
- Your data, your Drive. Records sit in a Google Sheet you own and can back up with the built-in backup command.
- Working from day one. The seeded demo business shows how every module connects before you enter your own projects.
- Fully editable. Trades, BOQ categories, expense categories and site areas are managed in List Management, and the full source code is included.
Opportunities for Improvement
- There is no Gantt chart or dependency scheduling; timing is handled through task due dates and the Two Week Look Ahead report.
- Invoices are internal billing records. The system does not file tax returns or connect to accounting software.
- Google Apps Script has daily quotas and execution time limits, so very large businesses should archive old records regularly with Database Archive.
- Inspections are internal quality records; the system does not certify compliance with any building or safety standard.
- After any code change you must deploy a new version for the live URL to update.
Best Practices
- Try each role in the live demo first, then decide which of the seven roles your team needs and trim the permissions.
- Set company details, currency symbol, GST %, retention % and print size in Settings before you print the first quotation.
- Agree package weights at the start of each project so the progress figures mean the same thing on every site.
- Close snags in the system the same day they are fixed, so the handover snag count stays accurate.
- Use Database Archive at year end to keep the live tables fast.

Frequently Asked Questions
Can I try the Interior Fit-Out Project Management System before buying?
Yes. The live demo above runs the full web app 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 buy anything.
What do I need to run it?
Only a Google account. The web app runs on Google Apps Script and creates its own Google Sheet database in your Drive during setup. Team members sign in with user names you create, so they do not need their own Google accounts.
How long does setup take?
About 15 minutes. Paste two files into a new Apps Script project, deploy it as a web app and run setup once from the first-run panel or the editor. Setup resumes on its own if Google’s time limit interrupts it.
How does it compare to Procore or Buildertrend?
Those are subscription platforms with scheduling, mobile apps and integrations. This interior contractor management software is a one-time purchase covering quotations, packages, snags, procurement and billing on your own Google account, without Gantt scheduling, offline use or accounting integrations.
Can I change the currency and tax rate?
Yes. The demo shows Indian Rupees and GST, but Settings lets you change the currency symbol, default GST %, retention %, credit days, company details and the print size used on quotations, orders and invoices.
Is there a limit on users or projects?
There is no licence limit on users or projects. The practical limits are Google Apps Script quotas and Google Sheets size, which is why the system includes Database Archive for moving old records out of the live tables.
