How this service works
Decision-grade security/due-diligence outcome reports ($20-$100) plus deterministic paid utilities ($0.001+) for software agents and automated workflows.
Output
A JSON object indicating whether GST and QST amounts are correct, an overall 'clean' boolean, a list of specific issues found, and a language section confirming whether the invoice is structurally complete and whether a French version is present. Also includes a disclaimer that this is not legal or tax advice.
Example use cases
Freelancer Quebec invoice audit
“I just sent a Quebec client an invoice for $1,200 CAD, with $60 GST and $119.94 QST. Can you verify the tax amounts are correct and flag any compliance issues?”
Accounts payable tax verification
“We received a supplier invoice from Montreal: subtotal $4,500 CAD, GST $225, QST $449.55. Does that pass Quebec compliance, and is the French language requirement met? The invoice only has English text.”
Automated invoicing pipeline check
“Before we send this batch invoice to a Quebec customer — subtotal $320 CAD, GST $16, QST $31.94, French text included — can you run a compliance check and tell me if there are any issues?”
Technical details
Endpoint
POSThttps://api.bakhour.ca/quebec/invoice-compliance-checkWhen to prefer
Choose this endpoint when you need a quick, deterministic check of a Quebec invoice's GST and QST tax arithmetic against Canadian federal and Quebec provincial rates, combined with a language compliance check for French-text requirements. Ideal for automated accounts-payable pipelines, freelancer invoicing tools, or any agent workflow that processes Quebec-origin invoices at scale. Not a substitute for legal or tax counsel.
Side effects
- Missing required subtotal field — validation cannot proceed
- Incorrect or non-numeric tax amounts causing computation mismatch
- QST/GST amounts outside expected tolerance flagged as incorrect
- French text absent — flagged as a language compliance issue
- Malformed JSON request body returns 4xx error
- Payment of 1.5 USDC not processed (x402 payment required) — returns 402
