D365 Finance Functional Architect | Contract | Outside IR35 at WeDo Technology Solutions Limited, London, £600-£900 per day

D365 Finance Functional Architect - AR / Payments / Tax / Subscription Billing | Contract

We are looking for a highly experienced Microsoft Dynamics 365 Finance Functional Architect to join a major enterprise finance transformation.

This is a specialist Finance role rather than a broad D365 F &O position. We need someone with genuine depth across Accounts Receivable, Cash & Bank Management, taxation, payments and Subscription Billing , capable of designing solutions for complex and sometimes non-standard accounting scenarios.

The programme is moving a large home installations finance operation onto an existing D365 F &O environment, covering billing, deposits, revenue recognition, consumer finance, payments, refunds, reconciliation and financial reporting.

Many of the target processes are still to be defined, making this a hands-on functional architecture and discovery role rather than simply implementing an established design.

The Role

You will own the detailed D365 Finance functional and accounting design , working alongside the Solution Architect, Finance stakeholders and technical teams.

Key responsibilities will include:

• Design D365 Finance configuration across Accounts Receivable, General Ledger and Cash & Bank Management .
• Define financial dimensions, chart-of-account additions, bank accounts and associated finance structures.
• Design customer deposit/prepayment processes including VAT recognition at receipt, deferred income and subsequent application against invoices .
• Define revenue recognition and posting approaches for installation-based billing.
• Configure and design Subscription Billing / billing schedules for one-off rather than traditional recurring transactions.
• Design tax configuration supporting multiple VAT treatments, mixed-rate invoices and date-effective tax changes.
• Own functional design for invoice amendments, cancel-and-reissue processes, credit notes, refunds, compensation and customer credit balances.
• Design bank reconciliation, settlement matching, suspense handling and finance exception reporting.
• Define the accounting and allocation model for consumer-finance/lender settlements , including high-volume remittance files, lender debtor accounts and commission recognition.
• Support payment allocation across card, lender finance, BACS, cheque and digital payment methods.
• Define standard and custom financial reporting requirements and support Trial Balance integration into SAP S/4HANA.
• Translate complex Finance requirements into robust D365 functional designs and clearly identify where standard functionality is insufficient.

Key Experience

This role requires significantly more depth than a generalist D365 Finance consultant. We are looking for:

• Deep functional architecture experience with Microsoft Dynamics 365 Finance / D365 F &O Finance .
• Expert knowledge of Accounts Receivable and customer accounting .
• Strong Cash & Bank Management , settlement and reconciliation experience.
• Strong understanding of UK VAT and D365 tax configuration , ideally including mixed-rate and date-effective tax scenarios.
• Experience with customer deposits, prepayments, deferred income and revenue recognition.
• Strong knowledge of Subscription Billing / billing schedules within D365 Finance.
• Experience designing complex credit, rebilling, refund and invoice-correction processes.
• Experience with high-volume payment/remittance allocation or complex debtor settlement processes.
• Ability to understand and defend the accounting treatment behind the proposed system design rather than simply configure requirements provided by others.

Experience with Worldpay or comparable payment providers, consumer-finance/lender settlements, SAP S/4HANA integration, utilities or high-volume consumer billing would be particularly valuable.

This is a role for a genuinely senior D365 Finance specialist who can sit with Finance stakeholders, understand the accounting problem and determine how it should be represented within Dynamics - including recognising when standard F &O functionality will not be enough.
