AI-powered invoice tracking for auto repair shops

My father-in-law runs an automotive repair shop. He has poor visibility into the invoices he receives from vendors — they arrive by mail or email, pile up on the counter, and most months end with him handing the accountant a shoebox of paper from a dozen different vendors. ShopLedger turns those invoices into structured data with one upload.

How it works

1

Send invoices

Upload PDFs through the web app, snap a photo and text it to your ShopLedger number, or forward email invoices directly.

2

AI extracts the data

Claude reads each invoice and pulls out vendor, line items, totals, dates, and auto-categorizes the spend.

3

Review and export

See spend breakdowns by vendor, category, and month. Edit anything the AI got wrong. Export a clean CSV for your accountant.

Three ways to submit invoices

Meet the shop owner where they are — not everyone wants to open a laptop.

Web Upload

Drag and drop PDFs or images into the browser. Batch upload supported.

Mobile

Coming soon
