From Sunday Night Spreadsheets to Automated Invoice Processing - A Restaurant Owner's Story

It started with a zip-lock bag full of invoices and a frustrated friend.

“Every Sunday night, same routine,” James told me over a beer at his bar. “I take home all the supplier invoices from the week, spread them out on my kitchen table, and spend hours typing everything into a spreadsheet.”

As the owner of a busy downtown bar, James needed to track his food and beverage costs carefully. But the process was stealing his one night off – time he should have been spending with family or planning his business’s future.

What made it more frustrating? The invoices were already in his email inbox. They were printed out during the week, stored in that zip-lock bag, and then manually entered into a spreadsheet. It was a digital-to-paper-to-digital journey that was wasting hours of valuable time.

The Real Cost of Manual Data Entry

For James, like many restaurant and bar owners, tracking costs is crucial. But the process was:

  • Taking 3-4 hours every Sunday night
  • Prone to human error from late-night data entry
  • Delaying insights into spending trends
  • Creating unnecessary paper waste
  • Adding stress to an already demanding job

Building a Better Solution

We knew there had to be a better way. Working closely with James, we built a simple system that would:

  1. Process invoices forwarded from his email
  2. Use AI to extract and categorize every line item
  3. Automatically populate his Google Sheet
  4. Flag any unusual prices or quantities

Using OpenAI’s Assistant API, we created a specialized system that could understand supplier invoices – from simple beverage orders to complex food deliveries with varying units and pricing structures.

How It Works

The solution is remarkably simple to use:

  1. Receive invoices from suppliers as usual
  2. Forward them to a dedicated email address
  3. AI extracts and categorizes each line item
  4. Data flows directly into your Google Sheet
  5. Weekly summary reports highlight key trends

No changes to your supplier relationships. No complicated software to install. Just forward your invoices and we handle the rest.

The Results

For James, the impact was immediate:

  • Sunday nights reclaimed for family time
  • More accurate data entry
  • Real-time visibility into costs
  • No more paper storage
  • Faster insights into pricing trends

“I actually look at my numbers more now,” James told us recently, “because I’m not burnt out from entering them manually. I spotted a supplier’s price increase within days instead of weeks.”

Beyond One Bar

After seeing the impact on James’s business, we realized this was a common problem across the industry. Every restaurant and bar owner we talked to had their own version of the “Sunday night spreadsheet routine.”

That’s why we’ve made our Invoice Capture system available to other businesses. Whether you’re dealing with five invoices a week or fifty, the system scales to match your needs.
