A supplier sends an invoice on Friday afternoon. It is in Italian, priced in dollars and includes a VAT reference you need to check. If it sits in an inbox until month-end, it becomes one more document to chase, enter and reconcile under pressure. Knowing how to upload supplier invoices properly turns that recurring admin job into a controlled daily workflow.
For most businesses, the best process is not about choosing a perfect file name or building a complex approval maze. It is about getting every invoice into one place quickly, preserving the original document, and letting the right checks happen before VAT reporting begins.
How to upload supplier invoices: choose the easiest route
The right upload method depends on how your business receives documents. A freelancer handling a handful of monthly bills may prefer to forward invoices from their inbox. A growing SME with staff buying supplies may need a quicker route from a phone. An accountancy firm may need a consistent method across several clients.
Use the route that creates the least resistance for the person holding the invoice. If a process is too fussy, documents will remain in personal inboxes, WhatsApp chats or paper piles until the deadline is close.
Upload by email
Email forwarding is usually the simplest option for PDF invoices received from suppliers. Forward the original email or attach the invoice to your dedicated processing address. Where possible, send the original PDF rather than a screenshot or a printed-and-scanned copy. A native PDF is clearer, easier to read and retains useful information such as document references and page order.
Create a simple internal rule: any supplier invoice received by email is forwarded on the day it arrives. Do not wait until payment is due. The invoice date, not just the payment date, may matter for bookkeeping and VAT timing.
For recurring supplier emails, set up a forwarding rule only if you are confident it will not capture irrelevant documents such as delivery updates, statements or marketing messages. Automation is useful when it reduces work, not when it creates a new queue of exceptions.
Send invoices through WhatsApp
WhatsApp works well for invoices received as photos, paper receipts or documents shared by staff while they are away from their desk. Take a clear photo in good light, include all four corners of the page, and send each invoice once. If an invoice has multiple pages, make sure every page is included.
Photos are practical, but they have trade-offs. Creased paper, shadows, blurred text and cropped VAT numbers make extraction less reliable. A supplier PDF is always preferable when one is available. Use a photo when it is the fastest way to capture a document before it disappears into a glove compartment, site folder or desk drawer.
Use a dashboard upload for batches and review
Dashboard upload is the practical choice when you already have a folder of invoices, need to add several files together or want to check a document before submitting it. It is also useful for accountants collecting a month of client records.
Before uploading a batch, remove duplicates and non-invoice documents. Supplier statements, purchase orders and delivery notes can be useful records, but they are not supplier invoices. Keeping document types separate reduces review time later.
What to check before you submit an invoice
You do not need to manually enter every field before upload. That defeats the point of invoice automation. You should, however, make sure the document is readable and complete. A quick check at the point of capture prevents a more expensive fix at month-end.
Check these four details before submission:
- The supplier name, invoice number and invoice date are visible.
- The total, currency and any VAT amount can be read clearly.
- All pages and supporting credit-note references are included.
- The document is an invoice or credit note, not a quotation, statement or duplicate.
If the invoice is missing a VAT number, has an unclear charge or appears to use the wrong legal entity, upload it but flag it for review. Do not quietly guess. The goal is not to force every document into a category. It is to identify the small number that need a person to make a decision.
Let automation handle extraction, not judgement
Once an invoice is uploaded, invoice-processing software can extract the supplier, date, invoice number, net amount, VAT amount, gross total and currency. It can also retain the original document as evidence, which matters when you need to trace a figure back to its source.
The strongest workflows learn from repeat suppliers. If the same telecommunications provider, software platform or wholesaler appears each month, the system should begin to recognise the supplier and apply the usual treatment. That reduces repetitive coding without forcing you to create rigid templates before you can start.
But supplier memory is not a substitute for review. A regular supplier can issue a credit note, bill a different service, change currency or charge VAT differently on a particular transaction. Automation should process the familiar work quickly and surface the unusual work clearly.
This distinction matters for business owners and accountants alike. The aim is not blind processing. It is fewer low-value decisions and more attention where VAT treatment, deductibility or supplier detail genuinely changes.
Handle Malta VAT and foreign currency with care
Uploading the document is only the first step. The accounting value comes from classifying it correctly.
For Malta businesses, supplier invoices can involve local VAT, EU supplier VAT, reverse-charge considerations, exempt items or purchases outside the EU. The right treatment depends on the supplier, the nature of what was bought, where it was supplied and the VAT status of your business. A software subscription from an EU business and office supplies bought locally may both be ordinary business expenses, but they do not necessarily belong in the same VAT category.
That is why a good upload workflow should capture the full invoice rather than only the total. The VAT number, supplier location, tax rate and description can all provide context for the correct categorisation. Where the document does not give enough information, send it for accountant review rather than treating it as a standard purchase by default.
Foreign currency adds another layer. Keep the original currency amount and invoice date with the document, then convert the value into euros using the rate and approach your accounts follow. Do not overwrite the original amount. You may need it later when matching the payment, checking exchange differences or answering a query about the supplier balance.
MyAccountant is designed around this workflow: submit an invoice by email, WhatsApp or dashboard, then let the platform extract data, categorise VAT, convert foreign currencies to euros and prepare Malta-ready monthly figures for review.
Build a routine that prevents month-end catch-up
The most effective invoice process is boring in the best way. Documents arrive, they are submitted promptly, exceptions are reviewed, and the month-end report is largely ready before the final week begins.
For a small business, a ten-minute check two or three times a week may be enough. Review newly uploaded invoices, resolve duplicates, confirm unusual VAT treatments and match anything that needs additional context. For a busier business, make invoice capture part of the accounts-payable routine each working day.
Accountancy firms should agree the intake method with each client at the start. Some clients will reliably forward everything by email. Others will send photos through WhatsApp. Do not insist on one channel if it causes delays. Standardise the destination and review process, while allowing clients to submit documents in the way they will actually use.
It also helps to separate invoice capture from payment approval. Uploading an invoice records what has been received. It does not have to mean the purchase is authorised for payment. Businesses with approval controls can retain those controls while still getting invoices processed early for bookkeeping and VAT purposes.
Common upload mistakes that create extra work
The most common problem is duplicate submission. An employee photographs an invoice, the supplier emails the PDF later, and both versions enter the records. Use invoice number, supplier and total to identify possible duplicates, but check carefully before deleting anything. Two invoices with the same total are not automatically the same transaction.
Another issue is uploading bank transaction screenshots instead of invoices. A bank line proves money moved. It rarely gives enough detail for VAT recovery, expense categorisation or audit support. Keep the supplier invoice alongside the payment record.
Finally, avoid holding invoices until they have been paid. Unpaid supplier bills still affect what you owe, what has been incurred and potentially the period in which VAT should be considered. Capture first, then manage payment status separately.
A good supplier invoice workflow should feel almost invisible: submit the document when it arrives, review only what needs judgement, and let your records stay current while the business keeps moving.
