Paperless Accounts Payable: How to Eliminate Paper from Invoice to Payment
Paperless accounts payable is an AP process where invoices are captured, processed and approved digitally from receipt to payment without printing, manual filing or physical sign-offs. According to Ardent Partners’ 2024 AP Metrics Report, organizations using fully automated AP processes achieve 5-day average invoice cycle times compared to 25 days for paper-based processes, an 80% improvement in efficiency.
KIP.ai by Axrail enables paperless accounts payable by accepting invoices from multiple digital channels, extracting data automatically, matching to purchase orders and routing for electronic approval. Axrail is an AWS Premier Partner. This guide covers what paperless AP means, the steps to eliminate paper, the cost savings and how to start without disrupting your suppliers.
What is paperless accounts payable?
Paperless accounts payable is an AP workflow where every step from invoice receipt to payment runs digitally. Invoices arrive via email, WhatsApp, API or SFTP rather than postal mail. Data is extracted by software rather than keyed by hand. Matching to purchase orders and delivery orders happens automatically. Approvals flow through electronic routing rather than paper on desks. Filing is digital rather than in cabinets.
The goal is not just to reduce paper but to remove the manual handling that paper creates. Every time a person prints, sorts, keys or files, there is cost and delay. Paperless AP addresses both by keeping everything digital from the start.
According to the Institute of Finance and Management, the average cost to process a paper invoice is $15.96, while an automated electronic invoice costs as little as $2.36. That is an 85% reduction in processing costs per invoice.
Why paper creates problems in accounts payable
Paper invoices introduce friction at every stage of the AP process. Understanding these pain points clarifies why going paperless delivers measurable improvements.
Slow receipt and routing. Paper invoices arrive by mail days after they are issued. They must be opened, sorted and routed to the right person before processing can begin. If someone is out of the office, paper sits on desks.
Manual data entry. Every field on a paper invoice must be typed into the accounting system: supplier name, invoice number, date, line items, quantities, prices, tax, total. The American Productivity and Quality Center (APQC) reports that manual data entry accounts for 42% of AP staff time in paper-based processes.
Keying errors. Manual entry introduces mistakes. A mistyped digit in an invoice amount or PO reference creates reconciliation problems downstream. The Institute of Finance and Management estimates that 3.6% of manually entered invoices contain errors that require correction.
Physical storage and retrieval. Paper invoices must be filed, and filed invoices must be retrievable. Searching through filing cabinets for an invoice during an audit or supplier query takes time that digital search eliminates.
Approval bottlenecks. Paper approvals require physical presence. When an approver travels or works remotely, invoices wait. According to Levvel Research, 62% of organizations cite approval delays as their top AP challenge.
Lost documents. Paper can be misfiled, damaged or lost entirely. The Association for Information and Image Management (AIIM) found that organizations lose 7.5% of paper documents and spend an average of $120 in labor costs searching for each misplaced file.
The paperless AP workflow
A paperless accounts payable workflow follows the same logical stages as a paper process but executes each one digitally.
| Stage | Paper process | Paperless process |
|---|---|---|
| Receipt | Mail delivery, sorting | Email, WhatsApp, API or SFTP capture |
| Data capture | Manual keying | Automated extraction |
| Validation | Visual comparison | System matching against PO and DO |
| Approval | Paper routing, signatures | Electronic workflow, digital sign-off |
| Filing | Physical cabinets | Cloud storage, instant search |
| Payment | Cheque or bank transfer | ERP payment run |
1. Multi-channel digital capture
In a paperless workflow, invoices arrive through digital channels. Email is the most common: suppliers send PDFs as attachments, and the AP system ingests them automatically from a dedicated inbox. KIP.ai also accepts invoices via WhatsApp (useful for field operations and suppliers who communicate that way), API (for high-volume suppliers with their own systems), SFTP (for batch file transfers) and shared folders.
The multi-channel approach means you do not need to mandate a single submission method. Suppliers continue sending invoices the way they prefer, and KIP.ai consolidates them into one queue.
2. Automated data extraction
Once captured, each invoice is read by document extraction software. KIP.ai extracts supplier name, invoice number, invoice date, PO reference, line items with quantities and prices, tax amounts and totals. Each extracted field receives a confidence score so your team knows which values are certain and which need a human check.
KIP.ai delivers 90% out-of-the-box extraction accuracy on supported documents. Fields with lower confidence are highlighted for review rather than assumed correct.
3. Automated matching
Extracted invoice data is matched against the purchase order and delivery order (or goods received note). This 3-way matching confirms that what was ordered, what was received and what is billed all agree. For more detail on matching, see 3-way matching in accounts payable.
Invoices that match within tolerance move forward automatically. Invoices with mismatches become exceptions, routed to your team for review.
4. Electronic approval routing
Approved invoices follow electronic routing based on your delegation of authority rules. Different invoice values or categories can route to different approvers. A maker reviews exceptions and low-confidence fields, and a checker gives final approval. Every decision is logged, creating a digital audit trail.
5. Digital filing and search
Approved invoices and all supporting documents are stored digitally. When you need to find an invoice during a supplier query or audit, you search by invoice number, supplier, date, amount or any other field rather than walking to a filing cabinet.
6. ERP posting and payment
Clean, approved data is sent to your ERP. KIP.ai integrates with Xero, QuickBooks, Oracle NetSuite and other systems. The invoice is posted and ready for payment according to your normal payment run schedule.
The numbers behind paperless AP
The business case for paperless accounts payable is well documented. Here are key statistics from industry research:
| Metric | Paper process | Automated paperless | Source |
|---|---|---|---|
| Cost per invoice | $15.96 | $2.36 | IFM 2024 |
| Processing time | 25 days average | 5 days average | Ardent Partners 2024 |
| Error rate | 3.6% | 0.8% | IFM 2024 |
| Staff time on data entry | 42% | 8% | APQC 2024 |
| Exception rate | 24% | 11% | Ardent Partners 2024 |
For an organization processing 2,000 invoices monthly, the cost savings alone are substantial: moving from $15.96 to $2.36 per invoice saves over $325,000 annually.
Steps to eliminate paper from accounts payable
Going paperless does not require a big-bang transformation. Most organizations transition in stages.
Step 1: Redirect invoice receipt to digital channels
Start by setting up a dedicated email inbox for invoices and asking suppliers to send there. Most suppliers already send PDFs by email; they just need the address. For suppliers who still mail paper, set up a scanning process: scan and email, or use WhatsApp mobile capture.
Step 2: Implement automated extraction
Connect KIP.ai to your invoice inbox. Invoices that arrive are automatically extracted into structured data. Review the extraction results initially to calibrate confidence thresholds and identify any supplier formats that need attention.
Step 3: Configure matching rules
Set up matching between invoices and your purchase orders and delivery orders. Define tolerance thresholds: how much price or quantity variance is acceptable before an exception is raised. See what happens when documents do not match for more on exception handling.
Step 4: Map approval workflows
Configure electronic approval routing to match your delegation of authority. Different invoice amounts or cost centers can route to different approvers. The maker-checker workflow ensures every invoice has a second review before posting.
Step 5: Connect to your ERP
Set up the integration between KIP.ai and your ERP. Approved invoices flow into the ERP for posting and payment. KIP.ai works with Xero, QuickBooks, Oracle NetSuite and other systems.
Step 6: Communicate with suppliers
Let suppliers know the new invoice submission process. Most will welcome the simplicity of emailing a PDF. Provide the dedicated inbox address and any specific requirements (such as including PO reference in the email subject).
Handling the transition from paper
The shift to paperless does not happen overnight. During the transition, you will handle both paper and electronic invoices.
Scan and route paper invoices. Paper invoices can be scanned and emailed to the KIP.ai inbox. They then follow the same extraction and matching workflow as native electronic invoices.
Track paper volume over time. Monitor how much of your invoice volume remains paper-based. Most organizations find paper drops steadily as suppliers shift to email. You can accelerate this by reaching out to high-volume paper suppliers.
Maintain digital filing from day one. Even during transition, store all processed invoices digitally. This builds your searchable archive and ensures consistency once you are fully paperless.
How KIP.ai enables paperless accounts payable
KIP.ai is built for paperless invoice processing. It handles every step from multi-channel capture to ERP posting.
Multi-channel intake. Invoices arrive via email, WhatsApp, API, SFTP or shared folders. You do not need to mandate a single submission channel.
Document extraction with confidence scoring. KIP.ai extracts invoice fields and scores each one for confidence. High-confidence fields proceed automatically; low-confidence fields are flagged for human review.
3-way matching. Invoices are matched against purchase orders and delivery orders. Matching happens before data reaches your ERP, catching exceptions early.
Maker-checker approval. Every exception is flagged for your team to review and decide. A maker reviews, a checker approves. Approvals are logged for audit.
ERP integration. Clean data flows to Xero, QuickBooks, Oracle NetSuite and other systems. Your ERP remains your system of record; KIP.ai is the pre-ERP layer that ensures clean data arrives.
FamilyMart Malaysia uses KIP.ai to process 2,000-3,000 invoices monthly in a fully paperless workflow. Invoices arrive by email, are extracted and validated automatically, and flow to Microsoft Navision for posting. Read the full story in how FamilyMart Malaysia automated supplier invoices.
Common concerns about going paperless
What if suppliers will not switch to electronic?
Most suppliers already send invoices by email. For those who do not, you can scan paper and email it into the system. Over time, paper suppliers naturally shift as they see the convenience of email confirmation and faster payment.
What about legal requirements for paper records?
In most jurisdictions, digital records with proper controls meet legal and audit requirements. The key is maintaining a tamper-evident digital archive with appropriate access controls. Check your local regulations, but electronic invoice storage is widely accepted.
How do we handle disputes without paper originals?
Digital invoices are the original in a paperless workflow. When a dispute arises, you retrieve the original PDF, the extracted data, the matching results and the approval history from the system. This is often faster and more complete than searching through paper files.
What about invoices that require physical signatures?
Electronic approval workflows replace physical signatures. The approval record in the system, with timestamp and approver identity, serves as the sign-off. For jurisdictions or contracts requiring wet signatures, you can implement electronic signature solutions alongside the AP workflow.
Measuring paperless AP success
Track these metrics to measure progress and impact:
Paper volume percentage. What share of invoices still arrives as paper? Target zero over time.
Cost per invoice. Calculate total AP cost divided by invoice volume. Expect this to drop as automation increases.
Cycle time. Days from invoice receipt to approval ready. Paperless processes should show significant improvement.
Exception rate. Percentage of invoices requiring manual intervention. Lower rates indicate cleaner data and better matching.
Touchless rate. Percentage of invoices that flow from capture to posting with no manual handling. See touchless invoice processing for more on this metric.
