How to Build a Touchless AP Process in Business Central

Touchless AP can sound more complicated than it really is. The goal is not to remove people from accounts payable or allow every invoice to post automatically. It is to let clean, predictable invoices move through Microsoft Dynamics 365 Business Central without unnecessary manual work.

Consider a supplier invoice that matches an approved purchase order. The goods have been received, the quantity is correct, the price is within tolerance, the supplier is active, the invoice is not a duplicate, and the accounting information is complete. There is no exception to investigate and no decision left to make.

Yet in many organizations, someone in AP still opens the email, downloads the attachment, enters the invoice, checks every field, sends it for approval, follows up, and posts it manually. The invoice is ready, but the process slows it down.

A touchless AP process helps finance teams automate routine invoices while directing people toward transactions that contain missing information, unusual activity, or real financial risk. For companies using Business Central, building that process requires more than adding a digital approval step. Invoice capture, validation, matching, tolerances, posting, and exception management all need to work together.

Here are some practical ways to build a touchless AP process that improves efficiency without weakening control.

Start With a Clear Definition of Touchless AP

One of the biggest misconceptions about touchless AP is that every invoice should move through the system without review. That is not a realistic or useful goal.

Some invoices should stop. A supplier may charge the wrong price, a receipt may be missing, the purchase order may not exist, or a non-PO invoice may need coding. A new vendor may require additional checks, while an unusually large amount may need another level of approval. Those situations need human attention.

Touchless AP is designed for the invoices that do not require those decisions. A clean invoice should be able to continue automatically when it meets conditions the organization has already approved. Those conditions may include a valid supplier, an approved purchase order, a completed receipt, acceptable price and quantity differences, correct coding, and no duplicate.

The system handles the predictable work while finance handles the exceptions. That is what makes the process both faster and more controlled.

Begin With the Invoices Most Likely to Succeed

Trying to automate every supplier and invoice type at once can make the project harder than it needs to be. A better approach is to begin with a predictable group.

Look for suppliers that submit invoices consistently, include the correct purchase order number, use stable pricing, and generate enough volume to make automation worthwhile. These invoices are usually the easiest place to establish a reliable touchless flow.

For example, a distributor may start with recurring inventory suppliers whose invoices regularly match purchase orders and receipts. A manufacturer may begin with material suppliers that follow agreed pricing and delivery processes.

More complicated invoices can follow later. Non-PO invoices, one-time suppliers, credit notes, prepayments, utility bills, and professional services invoices often require different controls. They do not need to be forced into the same process from the beginning.

Starting with a focused group helps finance test the rules, understand the exceptions, and improve the workflow before expanding it.

Make Sure the Purchasing Process Supports Automation

Touchless AP starts before the invoice arrives. Business Central needs accurate purchase orders, receipts, vendor records, dimensions, tax settings, and approval rules. If that information is missing or inconsistent, invoice automation will stop repeatedly.

For example, the system cannot match an invoice if the purchase order was never created. It cannot confirm delivery if the warehouse or project team has not recorded the receipt. It cannot validate the supplier if vendor records are duplicated or incomplete, and it cannot apply the correct coding if dimensions are missing from the purchase order.

These issues appear in AP, but they often begin somewhere else. That is why building touchless AP requires coordination across finance, purchasing, receiving, projects, and operations.

Purchasing needs to create accurate orders. Receiving teams need to record goods and services promptly. Department managers need clear approval responsibilities. Finance needs consistent vendor and accounting data.

When the upstream process is reliable, more invoices can move automatically. When it is not, AP becomes the team that fixes every gap after the invoice arrives.

Create One Clear Entry Point for Invoices

Invoice automation becomes harder when documents arrive everywhere. Some suppliers send invoices to a central mailbox, while others send them directly to employees. Branches may use separate addresses, paper invoices may be scanned locally, and employees may forward documents several days after receiving them.

This makes it difficult for finance to know what has arrived and what is still waiting. An invoice may sit unnoticed in someone’s inbox, the same document may be submitted twice, or AP may need to download, rename, and organize files before processing can begin.

A touchless process needs controlled digital invoice intake. Suppliers may still use different formats, but those invoices should enter one connected workflow. PDFs, scanned documents, structured files, and electronic invoices should become visible to finance as early as possible.

This gives AP a clearer starting point and reduces the risk of lost documents, duplicate submissions, and delayed processing. Truvio AP Automation for Business Central helps organizations connect invoice capture, validation, matching, approvals, posting, and exception management with Business Central.

The first requirement for touchless AP is simple: the system needs to see the invoice before it can process it.

Validate Invoice Data Before It Moves Forward

Capturing invoice data is only the first step. The system may read the supplier name, invoice number, date, currency, purchase order reference, tax, total, and line details, but those values still need to be checked against Business Central.

The supplier should resolve to an active vendor. The purchase order should exist and belong to that supplier. The invoice number should not already be registered. Currency and payment terms should agree with the vendor or purchase order, while line totals, tax, and invoice totals should reconcile. Required dimensions and accounting fields should also be valid.

This validation is what turns extracted information into reliable AP data. Without it, the organization may automate data entry while allowing incorrect information to move further into the workflow.

For example, an invoice may be read successfully but contain one incorrect digit in the purchase order number. If the system only captures the field, the invoice may be routed incorrectly. If it validates the field against Business Central, the issue can be identified immediately.

A touchless invoice should move forward because the data agrees with trusted ERP records and company policy, not simply because the document was readable.

Use Matching to Identify Clean Invoices

For purchase-order invoices, matching is the core of touchless AP. The system needs to compare what the supplier invoiced with what the organization ordered and received.

A clean invoice should confirm that the supplier matches the purchase order, the invoiced items were ordered, quantities agree with the receipt, prices are correct, tax and additional charges are acceptable, and the invoice total is accurate.

When everything agrees, the invoice can continue automatically. When something does not match, the system should identify the specific issue.

A missing receipt is not the same as a price difference, and a duplicate invoice is not the same as an unexpected freight charge. A quantity issue may need input from the warehouse, while a pricing problem may belong with purchasing. A project coding question may need the project manager.

Clear exceptions make it easier to send the invoice to the person who can resolve it. They also prevent AP from spending time investigating issues that belong elsewhere in the business.

Use Tolerances to Avoid Unnecessary Delays

Exact matching may sound like the safest approach, but in practice it can create more manual work than necessary.

Small differences are common. A supplier may include an approved freight charge, a currency conversion may create a minor rounding difference, a contract price may vary slightly, or tax calculations may differ by a few cents. Stopping every invoice for every difference does not always improve control.

Tolerances help the organization distinguish an acceptable variation from a meaningful exception. The right tolerance depends on the value and type of purchase.

A $10 difference on a $50 invoice may need attention. The same $10 difference on a $100,000 equipment purchase may not. A routine freight charge from an established supplier may be expected, while the same charge from a new supplier may require review.

Tolerances should reflect business policy and real financial risk. Their purpose is not to force more invoices through the system. It is to stop low-value differences from consuming the same time as material problems.

Do Not Reapprove Purchases Without a Reason

Approval workflows are one of the most common places where invoice processing slows down. A manager may approve the purchase request, the purchase order is created, the goods are received, and the invoice matches the order. The same manager is then asked to approve the invoice.

That may feel controlled, but it does not always add a new decision.

A stronger process uses approval where something still needs to be reviewed. A matched PO invoice within tolerance may continue automatically. A non-PO invoice may require coding and approval. A price difference may go to purchasing, while a missing receipt may go to the person responsible for confirming delivery. A high-value or unusual transaction may need additional authorization.

This makes approvals more useful. Approvers receive fewer routine requests, which makes it easier to recognize and respond to the invoices that actually need their attention.

The goal is not to remove approval. It is to avoid asking people to approve the same purchase twice.

Set Clear Rules for Automatic Posting

Posting creates the liability in Business Central, so the conditions for automatic posting should be clear.

An organization may decide that an invoice can post automatically only when the supplier is valid, no duplicate has been found, the purchase order and receipt match, differences are within tolerance, required coding is complete, and any necessary approvals have been finished.

The company should also decide which invoice types are eligible. Routine PO invoices from established suppliers may be strong candidates. Invoices from new suppliers, credit notes, prepayments, complex non-PO purchases, or unusually large transactions may still require review.

These rules make touchless AP easier to control and easier to explain. Finance can show why an invoice was allowed to post automatically and which checks were completed before it moved forward.

The goal is not automatic posting at any cost. It is controlled straight-through processing for invoices that meet clearly defined requirements.

Give Every Exception a Clear Owner

Touchless AP depends on what happens when an invoice stops. An exception should make four things clear: what is wrong, who needs to act, what needs to be done, and how long the invoice has been waiting.

A message that says “matching failed” does not give the user enough information. A more useful exception might show that the unit price exceeds the purchase order by $250, the approved tolerance is $100, and purchasing needs to review the difference.

That gives the user a clear path forward.

Ownership should follow the cause of the problem. Receiving teams should resolve missing receipts. Purchasing should review price and order differences. Project managers should confirm project-related costs. Finance should investigate duplicates, tax issues, and accounting errors.

AP should have visibility into the full process, but it should not become the messenger between every department. When exceptions are clear and well routed, invoices move faster and finance spends less time chasing answers.

Use Exception Data to Improve the Process

Exceptions are more than invoices that failed automation. They show where the wider business process needs attention.

If many invoices arrive without purchase order numbers, supplier instructions may need to improve. If one department regularly has missing receipts, its receiving process may need attention. If the same dimensions are corrected repeatedly, purchase order coding may need to be strengthened. If a supplier frequently invoices outside agreed prices, purchasing may need to review the contract.

Tracking these patterns helps finance increase automation in a controlled way. Instead of simply asking why the touchless rate is low, the team can identify which issues are creating manual work and address them at the source.

This is one of the biggest advantages of a connected process. AP automation does not only process invoices. It helps the organization see why invoices are slowing down.

Measure the Manual Work That Disappears

Processing time is useful, but it does not tell the whole story. An invoice can be processed quickly and still require several manual actions.

A better measure is how much routine work has been removed. Finance should track how many invoices post without manual entry, how many match correctly on the first attempt, how often coding needs to be changed, and how long exceptions remain unresolved.

It is also useful to understand how many invoices require approval and which exception types appear most often. Different invoice categories should be measured separately where possible.

PO invoices, non-PO invoices, freight invoices, credit notes, and utility bills may have very different automation potential. Combining them into one number can hide where the process is working and where manual effort remains.

The best touchless rate is not always the highest one. It is the highest rate the organization can achieve while maintaining accuracy, policy, and control.

Build Touchless AP in Stages

A successful touchless process usually grows over time. Start with one supplier group, one business unit, or one invoice category.

Define the conditions a clean invoice needs to meet. Configure capture, validation, matching, tolerances, routing, and posting rules. Then review what happens.

Look at which invoices moved automatically, which ones stopped, and whether the exceptions were legitimate. Check whether missing master data created problems, tolerances were appropriate, and the right people received the issues.

Use those findings to improve the process before expanding it.

This staged approach helps finance build confidence and demonstrate results without trying to redesign the entire AP function at once. It also makes adoption easier for purchasing, receiving, approvers, and other teams involved in the workflow.

A Better AP Process Should Make Finance Easier to Manage

A common mistake in finance automation is assuming that more technology means more complexity. The best AP improvements often do the opposite by making the process easier to understand, easier to track, and easier to improve.

For AP teams, that means less time spent entering invoice data, repeating checks, following up on approvals, and moving questions between departments. Purchasing and receiving teams receive clearer exceptions with better context, while approvers receive fewer routine requests and more meaningful decisions.

For the business, the result is faster processing, cleaner liabilities, better visibility, and a process that can support growth without creating the same increase in administrative work.

Touchless AP is not about removing control. It is about applying control where it matters.

Building Touchless AP Starts With Better Exception Management

Manual invoice processing can feel familiar, but familiarity is not the same as efficiency. When every invoice requires the same attention, finance spends too much time confirming what is already correct. Approvers receive unnecessary requests, genuine problems become harder to see, and growth creates more work instead of a better process.

A touchless AP process gives clean invoices a controlled path through Business Central and directs human attention toward the invoices that need it. The goal is not an AP process with no people involved. It is an AP process where people are involved for the right reasons.
