Invoicing rarely gets attention until something goes wrong. A delayed payment, a frustrated supplier, or a last-minute rush before the books close is often the first sign that something in the process isn’t working as it should.
In this article:
For many finance teams, slow invoicing isn’t caused by lack of effort. It’s caused by systems and workflows that haven’t kept up with how modern businesses operate. The good news? Most invoicing delays come down to a few common, fixable mistakes.
Below are three invoicing mistakes that consistently slow down finance teams — and what you can do to eliminate them.
Mistake 1: Relying on Manual or Semi-Manual Invoice Processing
Many businesses still handle invoices through a mix of emails, PDFs, spreadsheets, and paper. Even when invoices arrive digitally, key information is often entered manually (copy + paste) into accounting systems.
This approach creates friction at every step. Manual data entry takes time, introduces errors, and forces finance teams to spend hours correcting small mistakes. A single typo can delay approvals, payments, and month-end closing.
Over time, this adds up. What looks like “just a few minutes per invoice” quietly turns into hours, if not days of lost productivity each month — and significantly higher processing costs per invoice.
How to fix it
Moving to smart e-invoicing and automated data capture removes the biggest bottleneck. When invoices are received digitally straight into the accounting system and key data from PDFs is extracted automatically, finance teams can focus on validation instead of data entry. Fewer errors mean fewer delays, and invoices move through the workflow faster from day one.
Key takeaways
- Always prefer e-invoices, whether they arrive via the international Peppol network or a local e-invoice format. They are received into your
- When PDFs are unavoidable, use automated invoice digitization with AI-based data capture instead of manual entry.
Mistake 2: Unclear or Manual Invoice Approval Workflows
In many organizations, invoice approvals still depend on emails, forwarded messages, or informal agreements. Invoices are sent to the “right person,” but there is no clear visibility into who has approved what — or what is still waiting.
This lack of structure slows everything down. Finance teams spend time chasing approvals, invoices sit idle in inboxes, and payment deadlines creep closer. In the worst cases, invoices are approved late simply because no one realized they were pending.
Unclear approval workflows also create internal risk. Without defined rules or audit trails, it’s harder to ensure invoices are reviewed consistently and in line with company policies.
How to fix it
Automated approval workflows bring structure and transparency into the process. Clear rules based on your company’s needs ensure invoices are routed automatically to the right approvers based on amount, supplier, or department. Real-time status tracking shows exactly where each invoice is and what action is needed next.
Key takeaways
- Define clear approval rules instead of relying on emails and memory.
- Use automated workflows that provide visibility, accountability, and a full audit trail.
Mistake 3: Invoicing Systems That Don’t Integrate With Accounting Software
Many invoicing tools claim to “integrate” with accounting or ERP systems, but in practice this often means exporting files, uploading spreadsheets, or manually updating data between systems. While this may look acceptable on paper, it still creates friction for finance teams.
When data has to be imported, exported, or manually synced, errors are almost inevitable. Numbers get out of date, corrections take time, and finance teams lose confidence in whether the data they are working with is current. Month-end closing becomes slower, and reporting is delayed because systems are never fully aligned.
Instead of saving time, these so-called integrations introduce another layer of manual work — just in a different format.
How to fix it
Truly effective integrations run in the background and require no manual intervention. Invoice data should flow automatically and continuously between invoicing and accounting systems, without file transfers or duplicate data entry. When systems stay in sync in real time, finance teams can trust their data and work more efficiently.
Key takeaways
- Avoid “integrations” that rely on exporting and importing files or manual data updates.
- Choose invoicing solutions with seamless, automated integrations that keep accounting data accurate and up to date at all times.
- One process, one dataset — no parallel systems to maintain.
Faster Invoicing Starts With Better Systems
Slow invoicing is rarely a people problem. It’s almost always a process problem. By reducing manual data entry, structuring approval workflows, and connecting invoicing with accounting systems, businesses can dramatically speed up invoice handling without adding headcount. The result is faster payments, better cash flow visibility, and a finance team that can focus on higher-value work.
Fixing these three mistakes is often the quickest way to unlock immediate efficiency gains — and it sets the foundation for scalable, compliant financial operations.
