Review invoices with multiple tax registration numbers

An accountant reviewing several customer businesses needs to know whose invoices are being examined and which registration details appear on them. A tax total without that context can hide a business-selection mistake. Just Invoice records business information on invoices and provides tax reporting for authorized customer access. The practical review is to connect each questionable row to its PDF and its business identity, rather than combining everything into one unexplained number.

Distinguish the account from the business

A customer account can contain business records, while an accountant can connect to several customers. Those are different levels of organization. Begin by naming the customer and the business relevant to your review. Do not assume two trading names represent one registration, or that similar supplier names identify the same entity. If a customer has changed their legal structure, ask for the effective dates and professional guidance. The portal supplies documents; it does not determine the legal relationship between entities.

Inspect the document as issued

Open invoice PDFs from early and late in the review period. Check the seller identity, tax labels, and displayed registration information. When a number is missing or unexpected, preserve the invoice reference and ask the customer to confirm the details with their adviser. A current business setting alone does not explain every historical document. The invoice PDF review guide explains why the source document belongs alongside spreadsheet summaries, especially when a change occurred midyear.

Make a small registration review table

Keep the working table descriptive. Record the business name, document reference, displayed tax name, displayed number, and the question requiring confirmation. Avoid treating a guessed number as verified. If two numbers appear to conflict, identify the exact invoices rather than replacing either value in an export. For Quebec documents, retain distinct TPS and TVQ labels so the accountant can assess each separately. A row saying “confirm number on invoice 310” is useful even before the answer is available.

Keep report scope visible

Separate summaries where necessary to make the businesses and periods understandable. A combined report is convenient for locating activity, but it does not establish that all rows belong on the same return. Read the Quebec invoice-tax report guide before interpreting TPS/TVQ totals. The accountant still needs to consider activities outside Just Invoice, purchase documents, and other adjustments. Ask for registration or entity evidence through an agreed channel if the invoice itself cannot answer the question.

Correct the process, then address exceptions

Once the correct details are confirmed, make sure future invoices use the appropriate business information. Historical corrections require a deliberate process with the customer and accountant; do not erase the review trail for cosmetic consistency. Add registration checks to client onboarding when a new business joins the practice. Just Invoice is made in Canada for clear invoicing and document exchange. Professional verification of registrations and the treatment of each entity remains separate from storing and viewing those documents.
