Intro
Effectz.AI partnered with Hirdaramani Group of Companies to automate a document-heavy accounts payable workflow using E-Flow. The objective was not only to capture invoice data. It was to convert supplier invoices, invoice email instructions, validation rules, and ERP posting steps into a controlled AP execution workflow connected to Microsoft Dynamics 365 Finance & Operations.
E-Flow was configured to support invoice intake, data extraction, instruction handling, validation, exception review, dashboard visibility, and D365 invoice posting support through RPA-based automation. Since the solution has recently gone live, this case study focuses on the implemented workflow and operational value rather than post-live KPI numbers.
Client
Hirdaramani Group of Companies operates complex finance workflows across a large enterprise environment. Supplier invoices may arrive through email with attached invoice PDFs, supporting instructions in the email body, posting table details, PO references, product receipt references, currency details, VAT details, and corrections that need to be applied before ERP posting.
D365 Finance & Operations was already in place as the ERP environment. However, the AP process still required a workflow layer that could interpret invoice documents and email instructions together, prepare clean invoice data, support human review where required, and execute the posting process into D365 with better control.
The challenge
The business challenge was not simply invoice extraction. The AP process required operational interpretation across both documents and email context before an invoice could be posted correctly into D365.
This created several problems:
- Invoice data was spread across invoice PDFs and email body instructions
- AP users had to interpret supplier-specific formats, corrections, and posting instructions
- Local and foreign supplier invoices required flexible extraction and enrichment
- Invoice data had to be prepared in the correct format for D365 posting
- Invoice numbers, supplier details, PO references, product receipt references, currency, tax, subtotal, and totals needed validation before ERP entry
- Failures and mismatches needed to be reported clearly to users with reasons
- Finance users needed better visibility into invoice status across the workflow
The solution
Effectz.AI implemented E-Flow as the execution layer for AP invoice processing with D365 integration.
Instead of using AI only to read invoice fields, E-Flow was configured to support the full invoice execution flow: email-based invoice intake, invoice PDF understanding, email instruction extraction, business-rule validation, data preparation for D365, exception handling, dashboard monitoring, and RPA-supported ERP posting.
This allowed Hirdaramani to move from document capture to a more complete AP execution workflow.
How the automated workflow works
Step 1: Supplier invoices are ingested
Supplier invoices are received through email, with support for manual upload where required. E-Flow collects the invoice attachment and the related email body so that the document and instructions can be processed together.
Step 2: E-Flow reads the invoice and email body
E-Flow extracts key invoice information from the invoice PDF and operational instructions from the email body. This includes details such as company or site, vendor name, PO number, product receipt number, currency, subtotal, VAT percentage, VAT amount, corrected total, PO references, GRN references, and posting-related instructions.
Step 3: E-Flow validates and enriches the extracted data
The extracted data is validated against workflow requirements and prepared for downstream ERP handling. E-Flow supports enrichment steps such as supplier identification, translation where required, invoice number formatting, removal of special characters, and application of corrections or instructions mentioned in the email.
Step 4: Exceptions are routed for human review
If required information is missing, mismatched, or fails validation, the invoice is flagged for review. Users can view the status through the E-Flow dashboard, check failure reasons, correct the issue where needed, and allow the workflow to reprocess and validate the invoice again.
Step 5: E-Flow prepares the invoice for D365 posting
Once the data is validated, E-Flow prepares the invoice information in the format required by D365 Finance & Operations. This includes normalizing invoice numbers, identifying suppliers, applying email instructions, and preparing the data needed for invoice entry.
Step 6: RPA-supported posting is carried out in D365
RPA automation supports the D365 posting workflow by creating the invoice entry, entering the invoice data, attaching the supporting invoice document, validating key fields, and checking the invoice total against D365.
Step 7: Status, failures, and confirmations are reported
The workflow provides invoice status visibility through dashboards. Failed invoices are reported back to users with failure reasons, while successful processing can capture confirmation and posting details for traceability.
What E-Flow automated
With E-Flow in place, the AP team no longer needed to treat invoice processing as a fully manual document handling and ERP entry task.
E-Flow automated the core execution chain:
- Receive supplier invoices from email and supported upload channels
- Read invoice PDFs and extract invoice fields
- Extract operational instructions and posting details from the email body
- Validate and enrich invoice data before ERP posting
- Apply supplier, invoice number, tax, currency, PO, product receipt, and correction logic
- Route exceptions for human review where required
- Prepare validated invoice data for D365 Finance & Operations
- Support invoice entry, document attachment, and validation through RPA automation
- Report processing status, failures, and confirmation details through dashboards and email feedback
Business impact
Reduced repetitive AP handling
E-Flow reduces the amount of routine manual work required to read invoices, interpret emails, prepare invoice data, and enter information into the ERP workflow.
Better use of finance users' time
Finance users can focus more on exceptions, validation decisions, and process control instead of spending most of their effort on repetitive data handling.
Stronger handling of real-world invoice complexity
The workflow supports invoices where important information is not limited to the invoice PDF alone. Email instructions, corrections, posting details, PO references, and product receipt references can be processed as part of the same execution flow.
Cleaner data before D365 posting
E-Flow prepares invoice data before it reaches D365 by normalizing invoice numbers, removing unsupported characters, identifying suppliers, applying instructions, and validating key fields.
Improved exception management
Invoices with missing data, mismatches, or posting failures are surfaced to users with reasons. This makes exception handling more structured and traceable.
Greater process visibility
Dashboards give users visibility into invoice status, including processed, pending, and failed invoices. This improves operational monitoring and makes the workflow easier to manage across users and teams.
ERP automation without replacing the ERP
The solution works with D365 Finance & Operations rather than replacing it. E-Flow acts as the document execution layer that prepares and moves validated invoice data into the ERP process.
Outcome
- E-Flow went live as an AP invoice execution workflow for Hirdaramani Group of Companies
- Supplier invoices can be processed from email-based intake and supported upload channels
- Invoice PDFs and email body instructions are processed together
- Local and foreign supplier invoice workflows are supported
- Extracted data is validated, enriched, and prepared for D365
- Exceptions are routed through a user-facing dashboard
- RPA automation supports invoice entry and validation in D365 Finance & Operations
- Failure reasons and processing status are reported back to users
- The workflow creates a foundation for scaling invoice automation across broader AP operations
Why this matters
Many AP automation projects stop at document capture. But enterprise invoice processing often depends on the operational context around the document: email instructions, PO references, product receipts, tax details, supplier-specific formats, corrections, and ERP posting requirements.
Hirdaramani already had D365 Finance & Operations. What was needed was an execution layer that could connect supplier invoice documents and email-based instructions to the ERP workflow in a controlled and traceable way.
E-Flow closed that gap by combining document understanding, email instruction extraction, validation, exception handling, dashboard visibility, and D365 posting support in one AP workflow. That is what makes the implementation useful as an operational finance automation layer, not just an invoice extraction tool.
