What is the best way to automate supplier invoice processing?
Efficiency question :
Automating supplier invoice processing requires several elements to work together. A first step is to maintain a structured supplier list and, when the volume warrants it, use a dedicated email address for receiving invoices.
When invoices are received, an automated mechanism can save them and file them in the appropriate folders. Power Automate can handle this step. Data from the invoices can then be combined and consolidated with Power Query to facilitate processing and analysis.
It is also possible to go further by creating a custom Copilot agent that can participate in several stages of the process, from receiving the invoice through processing it according to established rules.
Key considerations:
Automation should be based on a robust, clearly defined process. You need to determine how invoices are received, where they are saved, what information must be retrieved and which rules must be applied before processing.
Confidentiality is also important. Folders containing invoices should be accessible only to authorized people and should be covered by appropriate backup and recovery mechanisms.
Challenges:
Not all invoices will arrive in the same format, and some will not match the expected rules. Exception mechanisms should therefore identify invoices requiring special attention rather than allowing automated processing to continue.
The rules must also correctly identify the supplier and prevent an invoice from being filed or processed in the wrong place.
Technology:
Several Microsoft technologies can be combined depending on the desired level of automation. Power Automate can manage the receipt, saving and filing of documents. Power Query can consolidate and transform the data required to process and analyze invoices.
A custom Copilot agent can also be integrated into the process to analyze information, apply rules and trigger the appropriate actions.
Developer's advice:
Before trying to automate the entire process, document the journey of a supplier invoice from receipt through final processing. Identify the rules that are always the same, the information required at each stage and, most importantly, the situations that require human intervention.
Also establish document access rules, backup mechanisms and exception handling from the outset. Effective automation should not only process compliant invoices quickly; it should also recognize situations that fall outside the expected process and route them to the right person.
