Everyone pays attention to outgoing invoices because collection starts there. However, in most businesses, the incoming invoice inbox is left unattended until the end of the month. Yet, the real risk accumulates right there.
An incoming invoice is not just an expense record; it carries deductible VAT, supplier balances, stock entries, and sometimes closes out a purchase order. When the inbox isn't cleared, all of these remain incomplete.
In this article, we covered a practical daily routine to clear the inbox, how to make acceptance-rejection decisions, and how to set up matching.

Why do invoices accumulate?
The reason for accumulation is not laziness, but ambiguity of ownership. Incoming invoices concern accounting, purchasing, and the warehouse alike. A task that concerns everyone often ends up being nobody's responsibility.
The second reason is access issues. Documents sit in the integrator portal, and only one person has the password for that portal. When that person is on leave, the inbox remains untouched for a week.
The third reason is indecision. When an invoice amount is higher than expected, the team says "Let me ask before processing" and waits for a response. Questions are asked, but follow-up is neglected.
The hidden cost of an accumulated inbox
Risk of VAT loss. Exercising the right to deduction depends on recording timing. Missing periods may lead to the loss of rights; confirm current practices with your financial advisor.
Incorrect balance. Unrecorded invoices make your debt to suppliers appear lower than it actually is, leading to flawed payment planning.
Reconciliation discrepancies. The supplier reports receivables according to their records, but there is no matching entry on your end. Correcting these discrepancies takes time, as we explained in the current account reconciliation article.
Missing rejection deadlines. Your right to reject an invoice under the commercial scenario is subject to strict time limits. When the inbox is checked late, erroneous documents are deemed accepted, making subsequent corrections much more cumbersome. We compared options in the cancellation and objection process article.
Daily routine: A fifteen-minute order
Instead of clearing the inbox once a month for four hours, clearing it for fifteen minutes every day is both easier and safer. Here is the sequence we recommend.
1. Scan incoming documents
List documents received in the last twenty-four hours using date filters. Reviewing the amount and supplier columns is usually a sufficient first screening.
2. Quickly clear expected invoices
Invoices with matching orders and correct amounts are processed without hesitation. These usually make up the majority of the list.
3. Flag suspicious items
Set aside documents with mismatched amounts, no matching orders, or from unknown suppliers. These will wait, but they won't get lost.
4. Assign pending items to specific owners
Saying "it was asked to purchasing" is not enough; it must be visible which document is pending with whom. Notifications bring this tracking down to the individual level.
Accept or reject?
Rejection is not a relationship-damaging move; it's a normal part of the process. However, not every discrepancy warrants a rejection. A practical distinction can be made as follows.
If the document contains errors in title, tax ID, or basic information, rejection is appropriate; the document must be corrected anyway. If there is a quantity discrepancy, compare it with the delivery note first — is it a short delivery or an erroneous invoice?
Price differences often require communication rather than rejection. If the agreed price differs from the invoice price, speaking with the supplier and opting for a difference invoice or return invoice leads to smoother progress.
The most helpful tool when making a decision is the reference document. If the order and delivery note are at your fingertips, decisions take only seconds.
Matching with orders
The heart of incoming invoice management is matching. Document headers must link to the correct current account, and line items to the correct purchase order lines.
Header-level matching is fast: if the total matches, pass it. Line-level matching is more precise, showing exactly which item has a discrepancy. We detailed the differences between these two methods in the document matching article.
When matching is established, inventory entries are automatically created simultaneously. The gap between goods receipt and invoicing is closed; the three-way control article explains this order.
If suppliers issue invoices using their own product codes, matching becomes difficult. Multi-code definitions solve this issue; you can check out the supplier cards and multi-codes article.
Who should handle this task?
The inbox must have a single owner. This person does not necessarily have to process the documents themselves; they are responsible for scanning the inbox daily and assigning pending items to respective owners.
Acceptance and rejection privileges should be kept restricted. Allowing everyone who can view a document to reject it creates risk. The authorization model separates viewing from processing.
In multi-company structures, inboxes must be separated by company. Users should only see documents within their own scope; the multi-company scope model ensures this.
This entire workflow operates within the e-Document module by gathering incoming, outgoing, pending, and canceled documents in a single list.
Period-end closing
Even if a daily routine is well established, a separate closing check is required at the end of the month. This check catches records that may have been overlooked during the period.
The first check is the list of documents received during the period but still unprocessed. This list must be empty; if not, the reason for each record must be explained.
The second check involves invoices not linked to an order. Some of these might be service purchases; however, if they are goods purchases, it means an out-of-process transaction took place. We addressed this loophole in the purchasing approval workflow article.
The third check is supplier balances. Unexpected balance discrepancies point to missing or duplicate records; refer to the current account reconciliation article.
Post-closing data is transferred to your financial advisor. If you use an existing accounting system, this transfer is planned via system synchronization; manual transfers are both slow and prone to errors.
This closing routine may take half a day during the first months. As the habit of daily scanning settles in, the time drops below an hour—and that is the real gain.
Frequently asked questions
Within how many days should I respond to an incoming invoice?
Rejection periods are limited under the commercial scenario. Confirm the current deadline with your financial advisor; the practical recommendation is to scan the inbox daily.
Will a rejected invoice be sent again?
Yes, if the supplier corrects the document and reissues it. Therefore, specifying the rejection reason shortens the subsequent cycle.
What should be done with an invoice that has no order?
First, verify whether a purchase was actually made. Setting up a purchasing approval workflow is an effective method to prevent unauthorized purchases.
How do I transfer documents to my existing accounting software?
System synchronization is used to plan transfers to Mikro, Logo, or Piconn.
The inbox is like a liability that grows silently. Fifteen minutes a day is much cheaper than four hours at the end of the month and dealing with overlooked discrepancies.
