Do you still send your accounting by email or WhatsApp? Real risks of the traditional model
Lost invoices in email chains
Attachments that are misplaced, threads that break, documents that are never accounted for on time.
No traceability or acknowledgement of receipt
You don't know which documents arrived, which were accounted for and which are pending review.
Sensitive documents in unsecured channels
WhatsApp and personal mail do not meet the security requirements for financial information.
Time wasted looking for supporting documents
When a request comes from the Treasury, spending hours searching for emails from months ago is not an option.
Manual errors in handover
Each time a document is forwarded and re-uploaded, the risk of accounting error increases.
No version control
If an invoice is rectified, there is no clean way to know which version is in force.
Your accounting relationship, sorted once and for all
Matrix Connect turns the back-and-forth of invoice emails into a single digital environment where everything is where it needs to be. You send, we receive, and we both see the same thing at all times. Without losing documents, without claiming acknowledgments, without eleven o’clock emails at night looking for a receipt.
At Sellarès Assessors we have integrated it into the daily flow of the accounting team: every movement is recorded, every document classified, and the historical file grows automatically without you having to do anything extra.
- A single working environment for the company and advisor
- Each document with date, author, and processing status
- No complex migrations or technical learning curve
