Managing supplier invoices is a major part of the work of accounting and finance teams. In many companies, the validation process is still largely manual: email exchanges, paper signatures, informal validations or multiple reminders.
This operation can lead to :
- delays in validation
- processing errors
- a lack of visibility on pending invoices
- risks of unauthorised payments
To meet these challenges, companies are setting up an invoice validation workflow, also known as a supplier invoice approval circuit.
Byautomating the invoice workflow, you can organise, monitor and secure the entire validation process before it is integrated into the accounts.
In this article, we will look at :
- what is the invoice validation workflow?
- the differences between a single circuit and a multi-level workflow
- how to set up automatic validation rules
- how to improve supplier invoice tracking
- and how to connect the process to accounting via automated exports.
What is the invoice validation workflow?
The invoice validation workflow is an automated process that defines the stages an invoice must go through before it is posted and paid.
This approval circuit determines :
- the people responsible for validation
- the order of validations
- invoice routing rules
- automatic notifications and reminders.
In practical terms, when a supplier invoice is received, it is integrated into an automated invoice management platform that automatically triggers the validation workflow.
Each validator then receives a notification enabling them to:
- approve the invoice
- to reject it
- request additional information.
All actions are logged, guaranteeing complete traceability of the validation process.

Why set up an invoice validation workflow?
Implementing an automated approval workflow brings many benefits to businesses.
Improve monitoring of supplier invoices
Thanks to a centralised dashboard and search filters, teams can quickly see :
- invoices awaiting validation
- validated invoices
- rejected invoices
- invoices ready for posting.
This considerably improves the monitoring of supplier invoices and avoids the loss of documents.
Speed up invoice processing
Invoice workflow automation means that invoices are automatically sent to the right people without manual intervention.
Validations are quicker and payment times more manageable.
Reducing errors and risks
A structured approval circuit helps to avoid :
- duplicate payments
- unvalidated invoices
- accounting entry errors.
Each invoice follows a clear, controlled process.
Reinforcing compliance and traceability
All actions (validation, rejection, comment) are recorded in the invoice history. This provides a reliable audit trail, which is particularly useful in the event of an internal or tax audit.
The different types of invoice validation circuits
Depending on the size of the company and the complexity of its internal processes, several types of validation workflow can be put in place.
Automated invoice management solutions generally allow two main types of circuit: simple or advanced, like those offered by Azopio. Our first two offers, LITE and PRO, offer simple validation, while the last two, ADVANCED and ULTIMATE, offer advanced validation: see details of our offers here: https: https://www.azopio.com/en/pricing/
The simple validation circuit (1 level)
The simple validation workflow corresponds to the most basic case: the invoice must be validated by a single person before being posted.
How it works
The process is as follows:
- receipt of supplier invoice
- integration into the invoice management platform
- automatic transmission to a single validator
- validation or rejection of the invoice
- export to accounting.
When should a simple workflow be used?
This type of circuit is particularly suitable for :
- VSEs and SMEs
- organisations with little hierarchy
- low-value invoices
- when the purchasing manager or executive validates all expenditure.
Advantages of the single circuit
The simple workflow offers a number of benefits:
- quick installation
- rapid invoice validation
- manageable process.
Even with a single level of validation, the company already benefits from automated monitoring of supplier invoices.
Advanced validation circuit (multi-level workflow)
More structured companies generally use an advanced validation workflow with several levels of approval.
In some solutions, such as Azopio, it is possible to configure up to 5 levels of validation.
Example of a multi-level approval circuit
An invoice, for example, might follow this path:
- operational manager
- department manager
- finance department
- general management
- accounting.
Each validator must approve the invoice before it goes on to the next stage.
Why use a multi-level workflow?
An advanced approval circuit enables :
- tighter budgetary control
- validation adapted to major expenditure
- better financial governance.
This type of workflow is particularly used in :
- structured SMEs
- ETIs
- multi-service organisations.
Set up automatic validation rules
One of the great advantages of modern invoice validation workflow solutions is the ability to create automatic routing rules.
These rules enable the approval circuit to be adapted according to different criteria.
Validation according to invoice amount
For example, a company might define the following rule:
- invoice less than €500 → approval by the department manager
- invoice between €500 and €5,000 → approval by manager + finance department
- invoice over €5,000 → approval by senior management.
So if an invoice exceeds a certain threshold, it is automatically sent to a further validation level.
Validation by document type
The simple or advanced workflow can also be configured according to the type of document:
- Supplier
- Customer
- Accounting document
- Bank
- Other document
For example:
- Telephony supplier invoices → IT department validator
- marketing invoices → marketing validator.
- Contract → finance + CEO
Add attachments and collaborate in the workflow
An advanced validation workflow does more than just approve an invoice.
It can also be used to centralise all related documents.
For example, validators can add :
- an order form
- a supplier contract
- a delivery note
- additional proof.
Users can also :
- leave a comment
- ask questions
- ask for corrections.
This facilitates collaboration between teams and improves the transparency of the process.
Simple workflow vs advanced workflow: what are the differences?
Depending on the size of the company and the complexity of its organisation, the validation workflow for supplier invoices may be simple or involve several levels of approval.
The table below compares the two approaches, using the Azopio solution as an example:
| Criteria | Simple validation workflow | Advanced validation workflow |
| Number of levels | 1 single level of validation | Several levels (up to 5) |
| Complexity | Quick and easy process | Structured, hierarchical process |
| Type of company | VSEs, small SMEs | Structured SMEs, ETIs, large companies |
| Validation | A single person validates the invoice | Several validators depending on the organisation |
| Automatic rules | Generally limited | Advanced rules (amount, service, supplier) |
| Receipt management | Possible attachments | Adding purchase orders, contracts and supporting documents |
| Traceability | Detailed monitoring of validations | Detailed monitoring of validations |
In practice, many companies start with a simple workflow and then move to a multi-level workflow as their organisation or invoice volume increases.
Invoice workflow automation: productivity gains for the accounting department
Automating the invoice workflow transforms a time-consuming manual process into a fluid digital workflow.
In particular, a dematerialisation solution enables you to :
- automatic invoice collection (email, scan, import)
- extract data using OCR and artificial intelligence (AI)
- automatically trigger the validation workflow
- notify validators
- restart pending validations.
As a result, accounting teams spend less time on administrative management and can concentrate on higher added-value tasks.
Accounting exports: connecting workflow to your accounting software
Once the invoice has been validated in the workflow, it must be entered into the accounts.
Automated invoice management solutions allow you to generate automatic accounting exports to avoid double entry.
Types of accounting exports
Information can be exported to :
- accounting software (Sage, ACD, Cegid, EBP, Cogilog, etc.)
- ERP
- financial tools
- accounting firms.
Exported data
Exports can include :
- the supplier
- the invoice number
- amounts exclusive of tax, VAT and sales tax
- the accounts
- cost centres
- analytical references.
This ensures seamless integration between the validation workflow and the accounting system.
Conclusion: the validation workflow, a pillar of automated invoice management
Implementing a supplier invoice validation workflow is now a key element in modernising corporate financial management.
Whether it’s a simple single-level circuit or an advanced multi-level workflow, automation enables :
- improve monitoring of supplier invoices
- secure validations
- speed up invoice processing
- reduce errors
- simplify accounting integration.
As electronic invoicing becomes more widespread, these tools become essential for structuring and automating financial processes.
