Accounts payable Services
Streamline your AP function with expert outsourced support from Viaante trusted by UK businesses to process invoices faster, reduce errors, and improve cash flow control.
What Are Accounts Payable Services And Why Do They Matter?
Accounts payable (AP) is at the core of every business’s financial operations. It encompasses every process involved in managing outgoing payments from receiving supplier invoices to approving, recording, and settling them on time. When managed poorly, AP creates bottlenecks, errors, and strained vendor relationships. When managed well, it becomes a strategic lever for cash flow optimisation and operational efficiency.
At Viaante, we provide fully managed outsourced accounts payable services for UK businesses of all sizes. Whether you’re processing dozens of invoices a week or thousands a month, our experienced AP teams and proven workflows ensure your payables function runs accurately, compliantly, and cost-effectively.
Viaante's Accounts Payable Services
We handle every stage of your AP cycle, from invoice receipt to vendor reconciliation. Our services are tailored to your business processes, volume, and software stack providing a seamless extension of your in-house finance function.
Invoice Data Capture and Processing
We receive invoices across all formats email, post, PDF, EDI, or supplier portals and capture data with precision using OCR technology and manual verification. Every invoice is coded, logged, and routed without delay.
Purchase Order (PO) Matching 2-Way and 3-Way
We perform both 2-way matching (invoice vs. PO) and 3-way matching (invoice vs. PO vs. goods receipt note) to validate every supplier invoice before it enters the payment workflow. Discrepancies are flagged and resolved before payment is authorised.
Vendor Invoice Verification
Each invoice is checked against supplier agreements, VAT registration details, and internal pricing schedules to confirm accuracy and legitimacy before processing. This layer of verification reduces the risk of overpayment and fraud.
Vendor Account Management
We maintain accurate, up-to-date vendor master records including payment terms, bank details, contact information, and VAT numbers ensuring your supplier database is always audit-ready and error-free.
Payment Scheduling and Processing
We schedule payments in line with agreed terms, prioritising by due date and available cash flow. We work with BACS, CHAPS, SWIFT, and other payment rails relevant to your suppliers domestic and international.
Expense Categorisation and Coding
Every invoice is mapped to the correct nominal code, cost centre, and project code, ensuring your management accounts and financial statements reflect accurate, granular spending data.
Duplicate Invoice Detection
Our quality control process actively scans for duplicate invoices using multiple matching parameters invoice number, supplier reference, amount, and date preventing erroneous double payments before they occur.
Exception Handling and Discrepancy Resolution
Where invoices fail validation or trigger exceptions pricing discrepancies, missing POs, or blocked approvals our team manages resolution directly with your teams or suppliers, keeping your AP queue clear.
Vendor Reconciliation
We regularly reconcile supplier statements against your purchase ledger to identify unallocated payments, missing invoices, and credit note discrepancies, giving you a clean, accurate payables position at all times.

TESTIMONIALS
What Clients Are Saying About Us
Global leader in E-procurement Operations
I was reviewing some invoices and I noticed that the team was doing an excellent job of identifying multi-invoices. Of the 100 I looked at 34 needed to be rejected and all 34 were correctly rejected. Thank you for being on top of it! We didn’t realize the processors were going to be sending in multi-invoices so we were nervous about them getting missed. Just wanted to pass on the good news and thanks!

Many thanks! May I take this opportunity to thank the entire Team for their efforts and dedication at this most difficult time.
I have every respect for their commitment in normal times, and I have some experience of what it is like to be locked away at home and working and all the challenges that bring with both family life and also the isolation of being away from one’s colleagues. Great work Team Viaante!
