An electronic <a href="/automated-accounts-payable-system">accounts payable system</a> captures supplier invoices as structured data, codes them to the general ledger, routes them for approval online, and keeps a timestamped record of every step. This guide explains how electronic invoice processing systems work, where products differ, what they cost, and exactly what AutoPayables does and does not do.

What AutoPayables actually does
The invoice side of electronic accounts payable, done properly. No matching engine, no payment rail, and we say so up front.
AI invoice capture
Forward invoices to a dedicated intake address or upload them. The AI extracts vendor, invoice number, PO number, dates, currency, subtotal, tax, discount, shipping, total, and line items, and stores a confidence score so you review only what the model was unsure about.
Line level GL coding
Every line on an invoice carries its own GL account. A facilities bill covering two properties or a supplier invoice with materials and freight gets coded correctly in one pass instead of becoming a manual journal entry at month end.
Vendor master
Vendors hold tax ID, 1099 status, payment terms, a default GL account, remittance and bank details, and an active or inactive status. Coding defaults follow the vendor, so repeat invoices need less handling.
Threshold approval with an audit log
Set one amount above which invoices require approval. Every submission, approval, rejection, and comment is written to an immutable log with the user and timestamp, which is the record an auditor asks for.
Purchase order records
Store purchase orders and their line items alongside your bills so the reference document is in the same system. Note that AutoPayables does not compare them or enforce tolerances; there is no matching engine.
REST API
On the Scale plan, post invoices to the upload endpoint and read invoices and vendors back as JSON. This is how data leaves AutoPayables today, and how teams wire it into their own reporting or ledger process.
How the electronic AP workflow runs
Four stages from a supplier invoice to a recorded liability.
Capture the invoice
Email the invoice to your intake address or upload it. The AI reads the document and produces structured header and line item fields, flagging anything it was not confident about.
Code it to the GL
Apply GL accounts line by line. Vendor defaults pre-fill the common cases, so a recurring invoice usually needs a glance rather than a decision.
Route for approval
Invoices above your threshold go to an approver, who approves, rejects, or comments in the browser. The decision is logged with the user and timestamp.
Record the payment
When the bill is paid from your bank or accounting software, record the payment and allocate it against the bill so the liability closes and the trail is complete.
Paper AP vs an electronic accounts payable system
The same invoices, handled two very different ways.
Manual, paper AP
- Invoice details retyped by hand into accounting software
- One GL account per invoice, splits fixed later by journal entry
- Approvals chased over email with no record of who said yes
- Vendor terms and 1099 status live in a spreadsheet
- Audit evidence reconstructed from folders and inboxes
- Finding an old invoice means searching the filing cabinet
Electronic AP with AutoPayables
- AI extracts header and line fields on arrival
- Each invoice line carries its own GL account
- Threshold routing with a timestamped approval log
- Vendor master holds tax ID, 1099 flag, terms, and remittance
- Approval history queried directly from stored records
- Search by vendor, invoice number, amount, or date
Who an electronic AP system suits
Where digitizing the invoice side pays for itself quickly.
Teams still keying invoices
If AP staff retype vendor, amount, and line details into accounting software every day, capture removes the slowest and most error prone step in the process. This is the clearest case for going electronic.
Cost tracked across jobs or properties
When one invoice covers several jobs, properties, or departments, line level coding handles the split at entry. Create a GL account per unit and code the lines to it rather than fixing it with journal entries later.
Controllers who need audit evidence
An approval log with user, comment, and timestamp on every invoice turns audit prep from a reconstruction exercise into a query. Pairs with accounts payable internal controls work.
Teams that pay from their bank already
If your payments run fine through your bank or accounting software, you may only need the invoice side automated. A payment run that builds the NACHA ACH file and checks for your bank closes the loop without paying for a payment rail you would not use.
What is an electronic accounts payable system?
An electronic accounts payable system is software that handles supplier invoices as digital data instead of paper: it captures each invoice when it arrives, turns it into structured fields, codes it to the general ledger, routes it for approval online, and keeps a timestamped record of every step. The term is used interchangeably with electronic payables, e-payables, and paperless accounts payable.
Going electronic is the first half of the problem. Actually running the function day to day, with vendor records, terms, coding rules and an approval trail in one place, is what accounts payable management software is for.
The category covers a wide range of products. At the light end are tools that capture and code invoices and hand the result to your accounting system. At the heavy end are mid-market and enterprise platforms that also match invoices to purchase orders and receipts, run multi-step approval hierarchies, and move money through their own ACH, check, and virtual card rails. Knowing where a product sits on that range is the whole buying decision, and most vendor pages are vague about it on purpose. This page is not. The same vagueness applies to the technology itself, which is why generative AI AP automation software is worth reading before you weigh another accuracy percentage.
What makes an accounts payable system electronic?
An AP system is electronic when the invoice exists as structured data from the moment it arrives, rather than as an image someone reads and retypes. That single change is what removes the keying, the lost paper, and the "where is that invoice" email thread.
In a manual process, someone opens the mail or the inbox, reads the invoice, types the vendor, number, date, and amount into accounting software, prints it, walks it to an approver, files the paper, and later reconciles what was paid against what was filed. In an electronic process, the invoice is parsed on arrival into vendor, invoice number, PO number, dates, currency, subtotal, tax, discount, shipping, total, and individual line items. Everything downstream reads those fields instead of re-reading the document. Capture is layer two of seven, and the accounts payable platform page walks through the rest in the order an invoice meets them.
How does an electronic accounts payable system work?
Most systems follow the same four stages, whatever the vendor calls them.
Capture. Invoices arrive by email to a dedicated intake address or by upload. OCR and AI read the document and produce structured fields. Better systems store a confidence score per extraction so a human reviews only the fields the model was unsure about, instead of re-checking everything.
Code. The invoice is assigned to general ledger accounts. This is where systems differ more than buyers expect. Some code at the invoice header only, which means a single invoice covering three cost centers gets forced into one account or split by hand afterwards. Others code at the line level, so each line on the invoice carries its own GL account.
Approve. The invoice routes to an approver by rule. Simple systems use one amount threshold. Mid-market platforms add department, vendor, cost center, and multi-step hierarchies with delegation and escalation. Every decision, comment, and rejection should be written to an immutable log with the user and timestamp.
Record or pay. The approved invoice is recorded as a liability and either exported to your accounting system or paid from inside the platform. Whether a product actually moves money is the single biggest functional split in this category.
What is the difference between manual and electronic accounts payable?
Manual AP depends on a person reading each invoice and retyping it, chasing approvals over email, and filing paper. Electronic AP parses the invoice into data on arrival, routes approvals in software with a timestamped trail, and keeps every document and decision in one searchable place. The practical differences are speed, keying accuracy, and whether an auditor can be handed evidence or has to have it reconstructed.
| Step | Manual, paper AP | Electronic AP system |
|---|---|---|
| Invoice arrival | Opened, printed, put in a tray | Parsed into structured fields on arrival |
| Data entry | Retyped into accounting software | Extracted automatically, humans review flagged fields |
| GL coding | Written on the invoice, keyed later | Applied in software, header or line level |
| Approval | Email threads and signatures on paper | Routed by rule, decision logged with user and time |
| Audit evidence | Reconstructed from folders and inboxes | Queried from a stored approval log |
| Finding an invoice | Search the filing cabinet or ask around | Search by vendor, number, amount, or date |
Is an electronic AP system the same as paperless accounts payable?
In everyday use, yes. Paperless accounts payable, electronic accounts payable, and e-payables all describe replacing paper documents and manual keying with digital records. If there is a shade of difference, "paperless" emphasizes removing physical documents while "electronic" emphasizes the data and the workflow. A system can be paperless and still slow if approvals sit in someone's inbox, so judge products on how invoices move, not on whether paper is gone.
What are electronic payables?
Electronic payables, often shortened to e-payables, is the broader term for handling the whole payables function digitally: digital invoice receipt, electronic coding and approval, digital records, and in many programs electronic disbursement by ACH or virtual card rather than printed checks. Card issuers and banks tend to use "e-payables" specifically for the payment side, where a virtual card program can earn rebates on spend. Software vendors tend to use it for the invoice side. Ask which one a vendor means before you compare quotes.
What does an electronic AP approval workflow look like?
An electronic AP approval workflow is a rule that decides who must approve an invoice, plus a record of what they decided. The minimum useful version is a monetary threshold: invoices above a set amount require approval before they can be recorded for payment, and each submission, approval, rejection, and comment is written to a log with the user and timestamp.
More complex organizations need more. Multi-step hierarchies send an invoice up several levels as the amount rises. Department, vendor, project, or cost center routing sends different invoices to different people. Delegation covers approvers who are out of office, and escalation moves an invoice on when it has been sitting too long. These are genuinely useful, and they are also the features that separate a $49 tool from a platform with an implementation project attached. Be honest with yourself about which you need, because paying for a routing engine you configure once as "everything over $5,000 goes to the controller" is a common and expensive mistake.
How do electronic invoice processing systems handle exceptions?
An exception is any invoice that cannot flow straight through: a price that differs from the purchase order, a quantity that does not match what was received, a missing PO number, a duplicate, a vendor not on file, or a low-confidence extraction. Systems handle these in three broad ways.
- Confidence flagging. The capture model marks fields it is unsure about so a human corrects those rather than reviewing every invoice.
- Validation rules. The system checks the invoice against reference data such as the vendor master or an open purchase order and holds anything that fails.
- Exception queues. Failed invoices land in a worklist owned by a person, with a reason code, instead of quietly stalling.
Two and three way matching against purchase orders and goods receipts is the most demanding form of exception handling and it is not universal. If matching is what you are buying, confirm the vendor stores goods receipts and performs the comparison itself, rather than simply displaying the PO next to the invoice. For the mechanics, see three way matching tolerances and invoice exception handling.
What AutoPayables does and does not do
Most pages in this category imply the whole category feature list. Here is exactly where AutoPayables sits, so you can rule it in or out in a minute instead of after a demo.
| Capability | AutoPayables |
|---|---|
| AI invoice capture by upload or email intake | Yes, with a stored confidence score per extraction |
| Header fields captured | Vendor, invoice number, PO number, dates, currency, subtotal, tax, discount, shipping, total |
| Line item capture | Yes |
| Line level GL coding | Yes, every invoice line carries its own GL account |
| Vendor master with tax ID, 1099 flag, terms, remittance details | Yes |
| Purchase order records | Yes, stored and viewable |
| Approval workflow | One amount threshold, with a full approval audit log |
| Multi-step, department, or vendor based routing | No |
| Reminders, escalation, out of office delegation | No |
| Two or three way PO matching | Yes, on vendor and amount within a tolerance percent you set |
| Duplicate invoice detection | No |
| Payment execution (ACH, check, virtual card) | ACH file and checks for your bank to send, no virtual cards |
| QuickBooks, Xero, NetSuite sync | Yes |
| REST API for invoices and vendors | Yes, on the $149 Scale plan |
If you need PO matching or a payment rail, buy a mid-market platform and budget for the implementation. If your bottleneck is keying invoices and coding them correctly to the GL, that is the part we do well, and the free trial is enough to test it on real documents.
Why line level GL coding matters more than most buyers expect
A single vendor invoice frequently spans more than one account: a facilities bill covering two properties, a supplier invoice with materials on one line and freight on another, a services invoice split across departments. Header level coding forces that invoice into one GL account and pushes the split into a manual journal entry later, which is where coding errors and month end rework come from.
Line level coding assigns an account to each line as the invoice is processed. If you track cost by job, property, plant, or cost center, create a GL account per unit and code the lines to it. That is the honest way to get job level cost out of a system built around a general ledger, and it works today. See GL coding in accounts payable for how to structure the accounts first.
How much does an electronic accounts payable system cost?
Pricing in this category takes three shapes, and vendors rarely publish enough to compare them directly.
| Model | How it is charged | Typical fit |
|---|---|---|
| Per user, per month | A seat fee for everyone who touches AP, plus a fee on each payment sent | Teams with few approvers and high payment volume |
| Per invoice or volume tier | A monthly fee tied to invoice count, users often unlimited | Teams with many approvers and predictable volume |
| Quote only | Modules, volume bands, and an implementation fee, negotiated | Mid-market and enterprise with matching and multi-entity needs |
For reference points on published numbers, see our Bill.com pricing, Tipalti pricing, and AP automation pricing breakdowns. AutoPayables publishes flat plans: a free trial for your first 20 invoices, Growth at $49 a month for 200 invoices, and Scale at $149 a month with unlimited invoices, unlimited users, and API access. On the Growth plan that works out to about 25 cents an invoice at full usage.
Whatever model you compare, build the all-in number: seats multiplied by the seat rate, plus payment fees at your real monthly volume, plus any implementation charge amortized over the contract. The headline rate is almost never the number you will pay. If you are weighing a long commitment, our notes on AP automation contract terms cover what to negotiate before signing.
How to choose an electronic accounts payable system
Work in this order and you will shortlist quickly.
- Write down your real bottleneck. Keying? Approval delays? Coding accuracy? Audit evidence? Payment execution? Buy for that, not for the longest feature list.
- Decide whether you need PO matching. If you run purchase orders and want price and quantity enforced, that requirement alone rules out most lightweight tools.
- Decide whether the system should move money. Many teams are happy paying from their bank or existing accounting software and only need the invoice side automated.
- Check the integration honestly. Ask whether the sync is live and bidirectional, a scheduled export, or an API you would have to build against.
- Test on your own invoices. Capture accuracy varies enormously by document type. Run your ugliest ten invoices, not the vendor's demo set.
- Price the whole contract. Seats, payment fees, modules, implementation, and the renewal increase.
For a wider view of the category, see accounts payable software, invoice approval software, and accounts payable audit software. If your invoices arrive as structured e-invoices rather than PDFs, e-invoicing software covers that path.
A narrower read of the same territory, focused on capture and coding rather than the whole system, is on accounts payable processing software.
Going electronic is the format change. What happens to the invoice once it is electronic is the subject of accounts payable invoice automation.
Going electronic is a decision about method. Which product category you buy is a separate one, and the accounts payable systems comparison covers the four options and what each costs.
Going electronic removes the paper but not necessarily the typing. If what you want is the whole chain running without someone rekeying figures, our page on the automated accounts payable system covers where the two ideas differ.
Frequently asked questions
An electronic accounts payable system is software that handles supplier invoices as digital data instead of paper. It captures each invoice on arrival, converts it to structured fields, codes it to the general ledger, routes it for approval online, and keeps a timestamped record of every step. It is also called electronic payables, e-payables, or paperless accounts payable.
Manual AP relies on a person reading each invoice, retyping it into accounting software, chasing approvals by email, and filing paper. Electronic AP parses the invoice into data on arrival, routes approval in software with a timestamped log, and stores every document and decision in one searchable place. The gains are speed, keying accuracy, and audit evidence.
In practice they mean the same thing. Paperless accounts payable emphasizes removing physical documents, while electronic accounts payable emphasizes the data and the workflow. Both describe replacing paper invoices and manual keying with digital records. A system can be fully paperless and still slow, so judge products on how invoices actually move.
Electronic payables, or e-payables, is the broader term for running the payables function digitally: digital invoice receipt, electronic coding and approval, digital records, and in many programs electronic disbursement by ACH or virtual card instead of printed checks. Banks and card issuers usually mean the payment side, software vendors usually mean the invoice side.
Some do and some do not, and it is the biggest functional split in the category. Platforms with their own payment rails send ACH, checks, and virtual cards from inside the product. Other systems automate invoice capture, coding, and approval and leave the transfer to your bank or accounting software. AutoPayables sits in between: it builds a NACHA ACH file, print-ready checks and a Positive Pay file from approved bills, and your bank moves the money.
No. AutoPayables stores purchase orders and vendor invoices, but it does not compare them or enforce price and quantity tolerances, and it does not store goods receipts. If matching is a requirement, choose a mid-market platform built for it. What AutoPayables does well is AI capture and line level GL coding on every invoice line.
Pricing takes three shapes: per user per month plus payment fees, a monthly fee tied to invoice volume, or a quote-only contract with modules and an implementation fee. AutoPayables publishes flat plans: a free trial for your first 20 invoices, then $49 a month for 200 invoices, and $149 a month for unlimited invoices, users, and API access.
Many do, through a live sync, a scheduled export, or an API. Ask which of the three a vendor means, because the words are used loosely. AutoPayables syncs approved bills, vendors and payments with QuickBooks Online, Xero and NetSuite, and the REST API on the Scale plan moves invoice and vendor data to other systems.
It decides who must approve an invoice and records what they decided. The basic version is an amount threshold: anything above a set figure needs approval before it can be recorded for payment. Larger organizations add multi-step hierarchies, department or vendor routing, delegation, and escalation. Every decision should be logged with the user, comment, and timestamp.
