AR Reinvented With AI: How a Financial Services Client Replaced Manual Backlogs With Autonomous Cash Application 

The client’s cash application process was a high-cost bottleneck. Daily payments—wires, ACH, and CHIPS—arrived with remittance details scattered across email bodies, attachments, and bank reports, forcing analysts to interpret and post each one by hand. The hardest part was reconciliation: payer names on bank statements rarely matched the billed entity, and cash seldom mapped cleanly to invoices—one invoice might be settled across several payments, or a single payment cover many—a problem that compounded when a customer had multiple invoices open at once.

What made automation fail in practice:

• Fragmented payment-to-invoice matching: Split payments and many-to-many invoice relationships made it hard to tie incoming cash to the right open receivables.
• Unstable remittance formats: PDFs, spreadsheets, and free-text emails shifted constantly, defeating brittle rules.
• Bank statement variability: Bank PDFs weren’t reliably extractable due to structural inconsistencies across pages.
• Identity ambiguity: Payer names didn’t align to customer or invoice records (abbreviations, parent entities, formatting drift).
• Business impact: Backlogs inflated unapplied cash and degraded daily close quality, increasing downstream disputes.

The client didn’t need a screen-scraping bot—they needed a reliable interpretation of real-world payment artifacts.

Evoke Technologies implemented an AI‑native, end‑to‑end cash application platform designed to operate at enterprise scale. The solution autonomously ingests payment data, interprets remittance information using large language models, matches payments to open invoices, and hands off validated results to RPA for ERP posting.
A Layered Matching Engine for Real-World Payments
The system uses a sequenced matching strategy to maximize auto-match rates in messy payment environments:

• Invoice numbers extracted from memo lines and validated through the Invoice API
• Email remittance cross-checks using amount and customer when memo data is unclear
• Cascading name matching that reduces customer names from full string to single token, applying similarity scoring at each step
• Reference-based matching using ACH trace numbers, CHIPS references, and bank-assigned IDs from mined bank statement data

Each match is enriched with invoice details, confidence scoring, and full or partial match status, then written to Oracle and exported for UiPath to post into the ERP.
Handles Data from Every Payment Source
The system brings together payment details from remittance emails and bank statements into a single matching flow.
It captures key information from incoming emails and attachments, then reads bank statements line by line to rebuild transaction data at scale.
Because payment formats change constantly, the design avoids brittle rules and keyword-based parsing. This makes the process more resilient, scalable, and easier to maintain.
Humans Handle Exceptions
Payments that cannot be matched with sufficient confidence are routed to a UiPath review queue. The AR team no longer works every transaction — only the true exceptions.
Auditable by Design
Every record captures match source, confidence score, Invoice API response, and timestamps. Credentials are encrypted at rest, and configuration is externalized so the platform can be extended without code changes. Finance and compliance teams get a complete, queryable audit trail for every applied payment.

The AR function transitioned from transaction execution to oversight, improving close velocity and cash visibility.

Evoke demonstrated that combining LLMs with structured database lookups and RPA produces automation that is both more intelligent and more resilient than traditional rule-based bots—capable of handling the inconsistent, real-world data that finance teams deal with every day.
