Receipt taxes and invoice taxes answer different questions

Distinguish taxes charged to customers from taxes appearing on business purchases. Understand why receipt storage does not calculate input tax credits or refunds.

Sales invoices show what the business billed. Purchase receipts support what the business bought. For tax-season preparation, keeping these two document collections distinct is more useful than adding all visible tax amounts into one spreadsheet cell. Just Invoice helps an accountant retrieve both kinds of evidence from an authorized customer account. It does not automatically decide whether a purchase tax amount can be claimed or whether an expense is deductible.

Identify the direction of the transaction

Start with a plain question: did your business sell something, or buy something? An invoice you issued is sales evidence. A supplier’s invoice or receipt is purchase evidence, even if its filename includes the word “invoice.” Upload supplier purchase documents into the receipt library, using the purchase date and an optional description. Keep invoices issued to your customers in the invoicing workflow. This distinction prevents a supplier bill from being mistaken for revenue during the accountant’s review.

Preserve purchase details before thinking about a claim

A total charged to a card does not necessarily reveal the supplier identity, purchased items, or separate taxes. Keep the full supplier document, including all relevant pages. Do not crop away details just because the final total remains readable. The accountant may need information that seemed unimportant when you took the photograph. The mixed-purchase guide explains how to add context when one receipt contains both business and personal items without altering the original evidence.

Understand the limits of a visible tax amount

Eligibility for an input tax credit or, in Quebec, an input tax refund involves more than finding a tax line. Registration, activities, use of the purchase, and supporting information can matter. Review the CRA’s input tax credit guidance and ask the accountant about your situation. This guide does not calculate a claim. A legible receipt is useful evidence, not an automatic approval of the purchase’s tax treatment.

Give the accountant a documented question

Suppose a hardware-store receipt includes materials for a customer job and supplies for home. Preserve the complete receipt and describe which items relate to the job. If you cannot separate them confidently, identify the uncertainty instead of inventing a percentage. The accountant can keep private review notes and follow up with you outside the portal. Include enough context to locate the transaction again: purchase date, supplier, job reference when appropriate, and the specific issue needing attention.

Assemble a package instead of a net-tax guess

Use the year-end checklist to gather the wider records the accountant requests. Keep the taxes charged report separate from any working assessment of purchase taxes. Other activity, adjustments, and prior information can affect the final return. Made in Canada, Just Invoice reduces document chasing and makes source files easier to find. The value is a clear handoff to the professional, while tax decisions and filing remain outside the receipt library.

Does uploading a receipt claim its taxes automatically?

No. Uploading stores a document for review. The accountant must assess eligibility and the required supporting information.

Can a bank statement replace every supplier receipt?

It can help trace a payment, but may omit purchase and tax details. Ask the accountant which additional evidence is necessary for the transaction.
