Building a Custom Inventory System When Spreadsheets Stop Working

Spreadsheets are great. Until they're not.

I built a custom inventory system for Hollow Bamboo Film Productions after their spreadsheet-based tracking fell apart. Hundreds of equipment items across 6 locations. Constant texting asking "where's the RED camera?" Paper lists that were always outdated.

Here's what I learned building the replacement.

When Spreadsheets Break

Spreadsheets fail when:

  • Multiple people update simultaneously. Conflicting versions, overwritten data.
  • Items move frequently. By the time you update the spreadsheet, the item moved again.
  • You need real-time visibility. Spreadsheets are static. Reality isn't.
  • You need mobile access. Editing a spreadsheet on your phone is painful.
  • History matters. Who checked out what? When did it come back? Spreadsheets don't track this well.

Hollow Bamboo hit all five. They needed something purpose-built.

What We Built

QR codes on every item. Scan with your phone to check in/out. No typing, no searching, no errors.

Mobile-first interface. Crew members on set don't have laptops. Everything works from a phone.

Real-time location tracking. See where every item is right now, not where it was when someone last updated a spreadsheet.

Complete history. Full audit trail of every movement. Who, what, when, where.

Multi-location support. Six warehouses/locations, one system.

The Technical Approach

Database: Airtable for the backend. Easy to modify, good API, non-technical team can manage it.

Mobile interface: Stacker for the mobile app. Connects to Airtable, provides native mobile experience.

QR codes: Generated unique codes for each item. Printed labels that crew can scan.

Notifications: Automated alerts when items are overdue or missing.

The Results

  • 20+ hours weekly saved - No more texting to find equipment
  • Complete visibility - Know where everything is instantly
  • Paid for itself in the first month

Client review: "Extremely attentive and responsive. Gave us an accurate timeline and met it. Highly recommend."

When Custom Makes Sense

Not every inventory problem needs custom software. Use off-the-shelf tools when:

  • Your process is standard
  • Volume is low
  • You can adapt to the tool's workflow

Build custom when:

  • Your workflow is unique
  • Off-the-shelf tools don't fit
  • Scale or complexity justifies the investment
  • You need specific features that don't exist

If spreadsheets are failing you and off-the-shelf tools don't fit, book a call. We'll figure out what makes sense for your situation.
