Far less manual invoice work
Invoices no longer need keying, coding, and chasing by hand before they reach Workday. Your AP team spends its time on the invoices that need a decision.
Integrations
Keep Workday Financial Management as your system of record. Rillion takes invoices from capture to approval and sends clean, approved data back to Workday, so AP moves faster without changing how finance runs.
Workday Financial Management handles supplier invoices, matching, and approvals through its business processes. Rillion adds AI invoice capture and coding, flexible approval workflows, and payment automation, so AP runs faster while Workday stays clean and accurate.
Invoices no longer need keying, coding, and chasing by hand before they reach Workday. Your AP team spends its time on the invoices that need a decision.
Invoices arrive in Workday captured, coded, and approved. That means fewer corrections, fewer reversals, and reporting you can trust.
Reorganizations, new entities, and new approvers are easy to handle. Your AP team can update approval rules in Rillion without starting a new Workday configuration project.
Invoices reach the right person straight away, and reminders keep them from sitting in a queue. Suppliers get paid on time, and month-end stays on schedule.
Every invoice, decision, and approval is recorded and searchable. When auditors ask questions, the answers take minutes to find.
Rillion doesn't charge per user, so every approver across every department and entity can take part without adding license costs.
Rillion AP automation
Invoices arrive by email, PDF, or paper. Rillion's AI extracts the supplier, PO reference, line items, amounts, and tax automatically, with around 95% accuracy from day one.

Rillion AI learns from your historical invoices and suggests the right accounts and worktags for each one. It gets more accurate with every invoice your team approves.

Rillion matches invoices against Workday purchase orders and receipts, including POs with hundreds of lines. Price and quantity differences are flagged and sent to the right person before anything reaches Workday.

Invoices are routed by company, cost center, amount, or your own rules. Approvers get automatic reminders and can sign off on desktop or mobile.

Approved header and line data post to Workday Financial Management with your companies, suppliers, accounts, and worktags intact. Master data stays in sync, so both systems match.

Pay suppliers by virtual card and earn a rebate on every payment. Rillion handles supplier onboarding, remittance, and reconciliation for you.

Every invoice, match, and approval is stored in one cloud archive. Find any invoice in seconds, with its full history attached.

Invoices arrive by email, PDF, XML, or paper, and Rillion reads each one with AI. It identifies the supplier against your Workday supplier records and extracts the invoice number, PO reference, line items, amounts, and tax. Nobody has to retype a thing.
For PO invoices, Rillion’s matching engine checks each invoice against the corresponding Workday purchase order and receipt, even when they have hundreds of lines. It supports both two-way matching (invoice to PO) and three-way matching (invoice, PO, and receipt). Invoices with missing information or price and quantity differences go to the right person before anything posts, so only clean, matched data reaches Workday.
For cost (non-PO) invoices, Rillion AI predicts coding based on your historical invoice data. It proposes distributions to the correct account, project, and cost center, then learns from every final posting, so proposals get more accurate over time. Need fixed logic for certain suppliers or cost types? Add your own coding rules alongside the AI.
Invoices are routed to approvers or exception handlers based on your rules. Approvers can see invoice status and payment timing and can sign off on any device, with automatic reminders keeping invoices moving. Once approved, header and line data are sent to Workday Financial Management for posting, and any exceptions follow predefined paths so nothing gets stuck.
Approvers can see invoice status and payment timing, sign off on any device, and get automatic reminders that keep invoices moving. Exceptions follow predefined paths, so nothing gets stuck.
Approved invoices can be paid through Workday's standard settlement process.
Alternatively, process payments directly in Rillion with Rillion Pay to automate vendor payments, eliminate paper checks, reduce costs, help prevent fraud, and gain better insight into payment status. In all cases, payment outcomes and remittance information are reflected back in Rillion for centralized archiving and future audits.
Rillion captures, codes, and matches invoices before they reach Workday. Approved header and line data post with your companies, suppliers, accounts, and worktags intact, so there's no rekeying and no cleanup, and Workday stays accurate and ready for reporting.
Many Workday AP tools stop at invoice capture and approval. Rillion also handles payment, with virtual cards, rebates on every payment, and supplier onboarding done for you. Workday then becomes a source of savings for AP, not just a place to process invoices.
Rillion has focused on AP automation for over 30 years. We involve our technical leads early, adapt to how your organization works, and give you a dedicated Customer Success Manager after go-live, so your AP process keeps improving long after implementation.
Testimonials
“I had thought at that time we could expand our AP process improvement into the other areas of the company but what I didn’t expect was how soon our CFO took advantage of the technology that Rillion had to offer.”
"[With Rillion,] we processed 20 invoices in 15 minutes — a task that previously took 2 hours. It’s a huge time efficiency gain."
"I like that with Rillion you see a pie chart of the expenses. So each month I can see that at a quick glance... which is nice, you know each day when I go through entering/posting the invoices I kind of look at that to see where we’re at."
"Rillion Prime allows us to decide for ourselves the best and most efficient way to process invoices. It was important to find a great, modern solution, and a provider that offers services in Finnish."
"From a finance perspective, the benefit is that invoice processing is now much smoother. Rillion Prime offers various features that enable further development and streamlining of operations. One significant aspect regarding smoothness, and efficiency of invoice processing, has been the ability to organize work roles in the best possible way to simplify the workflow."
