The supplier invoicing is a critical process because it combines legality, efficiency, and financial control. It’s not just about paying: it’s equally important to rigorously collect, validate, integrate, and reconcile each invoice. Even more so in the midst of the digital era. Therefore, for today’s CFO, working with a powerful and efficient system is not only an advantage but a necessity. If this applies to you, here we provide a checklist, best practices, a comparison of tools, and answers to the most frequently asked questions that most CFOs and executives ask about automated accounting and approvals.
Why Supplier Invoicing is So Important
First, let’s clarify why supplier invoicing is fundamental today. We are talking about an accounting process that, when well managed, has a great direct impact on several areas of any business. For example, it provides:
- Regulatory Compliance, as you avoid administrative and economic sanctions for late payments or formal errors.
- Operational Efficiency, as you free up time and resources to, for instance, perform more strategic analyses.
- Solid Supplier Relationships, which result from adhering to payment agreements.
- Treasury Visibility, which is fundamental for making responsible financial decisions.
Essential Elements for Managing Supplier Invoicing
However, for this process of supplier payments to function securely and efficiently, you must ensure that:
- There is a centralized repository for invoices.
- Automated validation is performed (tax ID, IBAN, due dates, etc.).
- It integrates with FACe for suppliers regarding public invoices.
- The approval workflows are auditable and immediate.
- The reconciliation is done with purchase orders, contracts, or delivery notes.
- Common formats are supported: Facturae, XML, PDF, etc.
- It generates alerts due dates and terms.
- Security is guaranteed security and backup (cloud, GDPR).
Common Supplier Invoicing Errors and How to Avoid Them
Moreover, in managing supplier invoicing, errors are often repeated in many companies, regardless of their size or sector. Detecting and preventing them leads to significant savings in time, money, and resources.
Based on our experience, the five issues listed below are the most common errors when invoicing suppliers.
1. Not verifying supplier information
- Problem: payments made with incorrect bank details or to unauthorized suppliers.
- Solution: establish an IBAN and CIF verification protocol before registering the invoice. If it’s with OCR, it’s more convenient.
2. Registering duplicate invoices
- Problem: double payment for the same invoice because it was received in different formats (paper, PDF, online portal).
- Solution: use a system with automatic duplicate detection by invoice number and NIF.
3. Lack of reconciliation with orders or contracts
- Problem: payments to suppliers for unauthorized amounts or concepts.
- Solution: link each invoice to its purchase order in the ERP before approval.
4. Ignoring the deadlines of the Late Payment Law
- Problem: by not meeting the stipulated deadlines, you run the risk of sanctions and reputational damage as a company.
- Solution: configure automatic alerts for payments that are close to their due date.
5. Not using standard electronic formats
- Problem: incompatibility with FACe suppliers or with the internal ERP.
- Solution: implement software compatible with Facturae and other accepted formats.
Precisely, each of these five solutions can be applied if you work with a solution like easyap’s.
