One supplier invoice can describe costs that serve two Businesses, but recording the full amount in both would duplicate the expense. Preserve the original document, identify the part supported for each Business and document the factual allocation used.

This is a recordkeeping method, not a rule for tax treatment. SilaTrail does not decide whether a cost is deductible or what allocation is appropriate. Ask a qualified professional when the connection or allocation is uncertain or material.

Separate the evidence from the decision

Start with the complete invoice or receipt. Record what was purchased, the service period, who paid and which Businesses received the goods or services. A supplier name alone is not evidence that both Businesses benefited.

If one document contains distinct line items, use those line items as the clearest starting point. If the cost is shared without separate lines, write down the factual basis used to divide it—such as measured usage, time, quantity or another supportable method. Do not invent a percentage after the fact merely to make totals fit.

Record the parts without duplication

Use this control sequence:

1. Keep one readable source document.

2. Identify the total amount and any tax shown.

3. Record only the supported portion in each Business.

4. Add a note describing the shared document and allocation basis.

5. Check that the portions do not exceed the original total.

6. Confirm the payment source and any owner-paid amount.

If the platform stores a copy of the document in each authorized Business, treat those copies as evidence for the same source—not as permission to record the full transaction twice. Private attachments must remain visible only to people authorized for that Business.

Review the result

During month-end review, compare the combined portions with the source invoice. Check dates, currencies, taxes, repayments and bank matches. If one Business later receives a refund, credit or correction, preserve the new document and update the affected record rather than changing both sides without an explanation.

The CRA requires business expense claims to be supported by an invoice, receipt, agreement or other voucher. The CRA also says to keep separate records for each business you run. A clear allocation note helps connect the source document to the separate records.

Frequently asked questions

Can I attach the same receipt to two Business records?

A controlled copy or authorized link may support both portions, but it should be clear that both records refer to one original document. Storage access must stay Business-scoped.

What if I cannot support an allocation?

Keep the document and mark the issue for review. Do not guess. Ask the Business owner or accountant to determine the appropriate treatment.

Should the two portions always add to the full invoice?

The records should explain the entire business-related allocation, but some parts may be personal, disputed or otherwise outside a Business record. Document the facts and seek professional guidance rather than forcing an unsupported result.
