A good approval workflow removes the waiting. PS **Pranjali Singh**May 12, 2023 ยท 4 min read An invoice approval workflow decides who must approve each invoice, in what order and within what time. When it runs on paper and email, invoices wait on desks and in inboxes, nobody can see where they are, and payments go out late. Finance teams spend their time chasing approvals rather than managing payables. This guide, refreshed for 2026, covers the eight most common approval workflow problems and a practical fix for each, from digital intake and clear rules to reminders, audit trails and reporting. Key takeaways - Digitize intake so every invoice is in one queue from day one - Define approval rules by amount, category and cost center - Automate reminders and escalation so nothing waits silently - Extract and match invoice data automatically - Keep an audit trail and report on cycle times and bottlenecks ## Problem one: paper based processes Paper invoices get lost, sit on desks and have to be scanned, posted or carried to approvers. Every step adds days and risk. **Fix:**move to digital intake. Ask suppliers to send invoices to one email address or portal, scan any paper on arrival, and route everything through one system. See [e-billing](https://aavenir.com/glossary/e-billing/). ## Problem two: no visibility or tracking Without a central system, nobody can see which invoices are waiting, where or why. Bottlenecks stay hidden until a supplier complains. **Fix:**use a workflow tool that shows the status of every invoice in real time to accounts payable, approvers and, where appropriate, suppliers. Dashboards should show invoices by stage and by age. ## Problem three: slow approvals and missed deadlines Approvals stall when approvers are busy, traveling or unsure whether they are the right person. Due dates pass and late fees follow. **Fix:**define approval workflows with clear roles, then automate notifications, reminders and escalation. If an invoice waits beyond a set time, it moves to a delegate or the next level. Approvers should be able to act from any device. See [invoice approval](https://aavenir.com/glossary/invoice-approval/). ## Problem four: manual data entry and reconciliation Typing invoice data into the accounting system is slow and error prone, and errors cause matching failures that send invoices back for rework. **Fix:**extract invoice data automatically and match it to purchase orders and receipts. Invoices within tolerance flow to approval; mismatches go to accounts payable with the difference highlighted. See [two way and three way matching](https://aavenir.com/what-is-2-way-3-way-matching/). ## Problem five: no standard process Different departments follow different approval rules, which confuses suppliers, approvers and accounts payable alike. **Fix:**standardize. Write down approval criteria by invoice type, amount and category, use checklists for review, and configure them once in the system so every invoice follows the same logic. Treat purchase order and non purchase order invoices differently, with rules for each. See [purchase order and non purchase order invoice approval](https://aavenir.com/best-practices-automating-invoice-approval-process-for-po-vs-non-po-invoices/). ## Problem six: poor collaboration Questions about an invoice bounce between accounts payable, approvers, procurement and suppliers by email, and context gets lost. **Fix:**keep comments, attachments and questions on the invoice record, so everyone sees the same history. Let suppliers see status and respond to queries through a portal. ## Problem seven: compliance and audit gaps Manual processes make it hard to show who approved what, when and on what basis, which complicates audits and regulatory reviews. **Fix:**store every invoice and supporting document in a secure digital archive with a complete audit trail of every action and approval. Enforce approval limits and separation of duties in the system. ## Problem eight: no analytics Without reporting, you cannot see where approvals slow down or which suppliers cause most exceptions. **Fix:**report on approval cycle time by step and approver, exception rates by reason and supplier, on time payment and discounts captured. Review the numbers monthly and fix the biggest bottleneck first.

Schedule a demo ## How does Invoiceflow handle approvals? In [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/), Aavenir AI extracts invoice data on arrival and matches it to the purchase order, receipt and contract. Invoices are routed by your rules, with reminders and escalation, and approvers act from any device. Exceptions go to an accounts payable specialist, who decides each one, and every step is logged. It runs natively on ServiceNow, where approvers may already work, or standalone. ## Where should you start? Map your current approval process, including the informal steps. Measure how long invoices wait at each stage. Then digitize intake, define the rules and automate reminders, in that order. Most teams see the biggest gains from removing waiting time rather than speeding up the review itself. ## The bottom line Invoice approval workflows slow down because of paper, unclear rules, silent waiting and manual entry. Digitize intake, standardize the rules, automate reminders and escalation, match data automatically, keep an audit trail and use reporting to fix the biggest bottleneck first. ### In this article - Problem one: paper based processes - Problem two: no visibility or tracking - Problem three: slow approvals and missed deadlines - Problem four: manual data entry and reconciliation - Problem five: no standard process - Problem six: poor collaboration - Problem seven: compliance and audit gaps - Problem eight: no analytics - How does Invoiceflow handle approvals? - Where should you start? **See invoice approval routing in Invoiceflow**Rules based routing, reminders and escalation, with a person deciding every exception.

An invoice approval workflow sets who must approve each invoice, in what order and within what time, based on rules such as amount, category and cost center. Automated workflows route invoices, send reminders and keep an audit trail. See [Invoiceflow](https://aavenir.com/solutions/accounts-payable-automation/). ### ### How can you speed up invoice approvals? Receive invoices digitally, extract and match data automatically, route by clear rules, send reminders and escalate invoices that wait too long, and let approvers act from any device. Report on cycle times to find bottlenecks. Learn about [invoice management](https://aavenir.com/glossary/invoice-management/). ### ### Should purchase order and non purchase order invoices follow the same approval?
