Link receipts to bank statement transactions

receipt-statement-linker

Python program that links receipts/invoices to bank statements, extracting data from both into a single json file.

Comamnd Line Options

• --receipt-input receipt.jpg - Receipt/invoice files to process
• --statement-input statement.pdf - Bank statement files to process
• --receipt-output output.json - JSON filepath for output
• --categorize - Turn categorization on
• --categories category1 category2 ... - Categories to use for categorization (optional)

Config file

The config file can be found at $XDG_CONFIG_HOME/receipt_statement_linker/config.toml. The config file has the following fields:

• transcription_model - model used for receipt & statement transcription.
• categorization_model - model used for receipt & statement categorization, if enabled.
• matching_model - model used for matching receipts to statement transactions when multiple transaction prices match the receipt price.
• categorization_notes - notes to provide extra context to the model when categorizing

Models are litellm model strings. You can find them by going here and selecting a provider.

Categorization

With categorization on, each entry will include a category for the transaction, and categorization for each item within the associated receipt. The default categories are:

DEFAULT_CATEGORIES = [
  "GROCERIES",
  "EATING_OUT",
  "TRANSPORTATION",
  "HOUSING",
  "HEALTHCARE",
  "PERSONAL_CARE",
  "ENTERTAINMENT",
  "SAVINGS_AND_INVESTMENTS",
  "DEBT_PAYMENT",
  "UTILITIES",
  "MISC",
]

Custom categories can be specified using --categories category1 category2 ....

Only labels may not be enough context for the categorization. To add more context to give to the model, you can add context in the config file like so:

categorization_notes = "'Liberty' is a theatre, so it falls under entertainment."

Supported Filetypes

The filetypes that are supported are based on whatever model is selected. The defualt is Gemini 2.5 Flash, and supported filetypes for this model can be found here.

A sample invoice and statement can be found under example/. The output of running it on these sample docs using the args --receipt-input example/invoice-sample.pdf --statement-input example/bank-statement-sample.pdf --categorize --receipt-output example/example.json is found under example/example.json
