Invoice Amount Consistency CheckerTASKWork only with a small readable invoice with quantity, price, tax and total. Recalculate displayed arithmetic using approved page code and flag discrepancies. Create a CSV file named webact-invoice-amount-consistency-checker.csv. Keep the complete file under 48,000 UTF-8 bytes. If required, propose a read-only run_js inspection of the current document for my explicit approval. Do not fetch URLs, access credentials, execute remote code or change page content. Use only observed content and facts I supply. Keep missing values unknown. Preserve IDs, dates, units and currencies. Report omitted, truncated or unreadable content; do not claim full coverage. Verify the output against the source and stop if the required input is unavailable. A small arithmetic check, not an accounting or tax-compliance audit. Decimal/currency rules need a tested fixture. Keep one header row, consistent columns, escaped quotes and literal spreadsheet-safe text. Ask me for any required settings or source facts that are missing before starting. Start with up to 25 records or one short document. Report exactly which source content was included. Setup: Specify the currency precision and rounding rule before recalculating amounts.

Can I use a scanned invoice or attachment?
Use readable HTML or supply the text on a normal webpage. Scanned documents, PDF parsing and attachment batches are outside these recipes. Review the output against the original before using it in your records.
Can I use this on the Free plan?
Yes. Install the Chrome extension, verify your WebAct account and use an available ChatGPT browser connection in the same Chrome profile. Free includes 25 user-started automation tasks per calendar month (UTC), shared across all tools. A task counts when its first action starts; steps and necessary retries within that task do not count separately. Provider limits apply. After 25 tasks, upgrade or wait for the reset.
Does this page run the task?
This page provides an illustrative example and a task to copy. Run it through WebAct on the source page you activate. Selected page context is processed by your browser AI provider. An ordinary answer in browser Chat uses no WebAct automation allowance; creating a file or changing fields in Task mode does.
