When several Businesses buy from the same supplier, the supplier name cannot determine ownership. Match every purchase using the invoice number, purchaser, Business purpose, service period, amount and payment source.

This is a practical recordkeeping method. SilaTrail does not decide which Business may claim a cost or how it should be classified for tax or accounting.

Capture the Business at intake

Ask the purchaser to identify the Business when the order is placed, not weeks later during reconciliation. Use a Business-specific reference, project code or delivery note where the supplier supports it. Save the complete invoice and record the service or goods in plain language.

If invoices arrive in one shared email inbox, route them into the selected Business only after checking the document. An email folder, sender address or bank descriptor is not authorization to expose the document across workspaces.

Match more than the supplier name

Use several facts together:

• invoice or receipt number;
• order and transaction date;
• amount and currency;
• purchaser or authorized contact;
• goods, services or project;
• service period or delivery details;
• payment account; and
• the Business that received the value.

This prevents a recurring software charge, fuel receipt or professional-service invoice from being copied into the wrong Business merely because the vendor is familiar.

Handle shared invoices deliberately

If one invoice actually covers more than one Business, preserve the full source and document the supported allocation. Record only the relevant portion in each Business and confirm the portions do not duplicate the original total. Leave uncertain items open for professional review rather than assigning them by habit.

Private receipt files should remain protected by the same Business boundary as the expense. Do not solve a matching problem by placing one unrestricted copy in a shared location.

Review recurring supplier activity

At month-end, group records by supplier within each Business and look for:

1. duplicate invoice numbers;

2. unexpected amounts or service periods;

3. charges paid from another Business’s account;

4. missing credits or refunds; and

5. attachments reused for unrelated transactions.

Then compare the supplier activity across Businesses at an owner level only to locate exceptions—not to merge the books.

The CRA says expense claims need invoices, receipts or other supporting vouchers and that separate records should be kept for each business. Clear supplier matching connects each source document to the correct record trail.

Frequently asked questions

Can I create one supplier profile for all Businesses?

A shared directory may reduce typing, but it must not merge transactions, attachments, payment details or access permissions across Businesses.

What if the invoice has no Business name?

Use order details, purchaser information, purpose and payment evidence. Add a factual note, and ask the owner if the destination remains unclear.

How do I prevent duplicate recurring charges?

Compare invoice numbers, service periods and amounts before recording. A new email or statement line does not necessarily represent a new expense.
