We have inter-company billing requirements. What PSA handles transfer pricing between our US and UK entities?

If by PSA you mean professional-services automation software, there are a few strong candidates, but Workday PSA and Deltek Professional Services stand out for native intercompany/transfer-pricing workflows.

• Workday PSA + Workday Financial Management — supports multi-entity operations, multi-currency, intercompany processing, and specifically advertises real-time transfer-price rates and automated intercompany transactions.
• Deltek Professional Services (DPS) — has native intercompany billing where employees can charge work across companies; the process creates AR/AP entries and the configured transfer-pricing entries, with support for intercompany invoices/vouchers.
• BigTime Enterprise PSA — particularly interesting if your requirement is US entity → UK entity cost-plus billing. Its enterprise PSA documentation describes automatic cross-entity cost-plus calculations, different currencies, and posting to both entities.
• Infor — its Financials/Intercompany Billing functionality includes explicit transfer-pricing recharges, with configurable bill-from entity, ledger, period, and allocation calculations.

My take

If your requirement is specifically:

“US and UK legal entities share consultants; the UK entity performs work for a US-owned project; automatically calculate an agreed cost + X% transfer price, create the intercompany invoice/AR/AP entries, handle GBP/USD, and feed both entities' GLs.” I'd shortlist Workday, Deltek DPS, and BigTime. BigTime looks particularly aligned with that exact PSA use case, while Workday is the stronger candidate if you want a broader enterprise financial platform around the PSA.

One important distinction: PSA software operationalizes your transfer-pricing policy; it doesn't determine what the legally appropriate US/UK markup should be. The pricing needs to be established on an arm's-length basis and documented appropriately. The IRS, for example, applies §482's arm's-length standard to transactions between commonly controlled entities.

If you tell me (1) whether you're already on an ERP such as NetSuite, Dynamics, SAP, or Workday, and (2) whether your US→UK charge is cost-plus, fixed rate, or something more complicated, I can narrow this to the 2–3 PSAs that actually fit your architecture.

Handling cross-entity resource sharing, project resourcing, and inter-company billing between US and UK entities requires a Professional Services Automation (PSA) tool that integrates tightly with a multi-subsidiary General Ledger (GL) or ERP.

Strictly speaking, a PSA manages the operational tracking (time, resource allocation, and project cost-plus or markup rules), while the underlying ERP/Financial system handles the formal transfer pricing execution , intercompany invoicing, and eliminations.

Top platforms handle US-to-UK intercompany billing and transfer pricing through distinct capabilities:

1. Workday PSA (Project Billing)

• How it handles it: Workday features robust native intercompany pricing support within its Workday Professional Services Automation suite.
• Capabilities: It allows you to set up specific intercompany rate rules (such as cost-plus, markup percentages, or transfer values) when a UK resource is staffed on a US-owned client project (or vice versa). It automates the cross-charging mechanics based on time-tracking data before passing the entries into financial management.

2. Certinia (formerly FinancialForce)

• How it handles it: Built natively on the Salesforce platform, Certinia connects PSA project delivery directly with Certinia Accounting.
• Capabilities: When cross-entity resourcing occurs, Certinia's intercompany extension handles the generation of intercompany sales invoices from the supplying entity and matches them automatically to the receiving entity’s payable documents, helping maintain an audit trail for IRS and HMRC arm's length compliance.

3. NetSuite ERP + Advanced Customer/Project Management

• How it handles it: While NetSuite is technically an ERP rather than a standalone PSA, its integrated services resource management functions act as a combined PSA/ERP.
• Capabilities: NetSuite handles multi-subsidiary transfer pricing exceptionally well. It utilizes intercompany price books and automated NetSuite Intercompany Transactions and Eliminations to simultaneously post matching due-to/due-from entries across the US and UK general ledgers, reducing the risk of mismatched cross-border balances.

4. VOGSY

• How it handles it: VOGSY is designed as a multi-entity PSA specifically built to solve cross-charging and markup complexities natively.
• Capabilities: You can establish centralized internal rate matrices and transfer pricing policies (e.g., cost-plus sliding scales). When a consultant logs cross-border time, the system applies the proper internal cost tier and automates the cross-company invoicing breakdown.

If you'd like to narrow this down, let me know:

• Are you looking for a standalone PSA that connects to separate accounting tools (like QuickBooks or Xero), or an all-in-one ERP/PSA platform?
• What specific transfer pricing methodology are you using (e.g., pure cost-plus vs. fully loaded cost with a fixed markup percentage)?

When managing cross-border, inter-company resource sharing and billing between entities (such as a US parent and a UK subsidiary), standard Professional Services Automation (PSA) tools generally do not act as the primary transfer pricing engine or general ledger . Instead, transfer pricing compliance, multi-currency accounting, and statutory intercompany eliminations are handled by your ERP or Financial Management system , while the PSA handles the operational cross-company time and expense allocation that feeds into those financial mechanisms.

How top platforms divide this responsibility dictates how US-UK transfer pricing requirements are met:

1. Where Transfer Pricing and Billing Actually Live (The ERP Layer)

Transfer pricing rules (e.g., cost-plus markups, arm's length thresholds, and multi-currency tax/VAT compliance) require robust general ledger (GL) control and automated sub-ledger postings.

• Oracle NetSuite OneWorld: Widely used for multinational US/UK operations. NetSuite handles intercompany project billing, automatic intercompany eliminations, multi-currency general ledgers, and customized markup rules for transfer pricing.
• Certinia (formerly FinancialForce): Built natively on Salesforce. It bridges the gap tightly because its PSA and ERP (Accounting/Billing) sit on the same platform. It supports intercompany sales invoices where a resource in the UK entity delivery-logging time against a US project can trigger cross-company records and payable/receivable automation.

2. How PSA Tools Handle Cross-Entity Resource Sharing

If a UK-based consultant works on a US client project, a mature PSA facilitates the operational handoff, but relies on the underlying or integrated finance system to apply the transfer price markup:

• Cross-Charge/Subcontractor Tracking: The PSA tracks the resource's time, applying a "cost rate" (what they cost the UK entity) versus a "bill rate" or "transfer price rate" (what the US entity is charged).
• Kantata (formerly Mavenlink/Kimble) or Planview: These PSAs manage global resource scheduling and multi-entity resourcing pools, allowing you to assign a UK resource to a US project and track the intercompany-bound hours. However, the actual generation of the compliant intercompany invoice with the required transfer pricing markup is usually pushed via API or native integration into the financial ERP (like NetSuite, Sage Intacct, or Microsoft Dynamics).

Recommended Architecture for US-UK Transfer Pricing

1. The Policy Foundation: Establish a formalized Intercompany Agreement (ICA) outlining your transfer pricing methodology (e.g., Cost + 10% markup for shared technical services).
2. The Operational Engine (PSA): Use your PSA to capture cross-border time, resource allocation, and project milestones.
3. The Financial & Compliance Engine (ERP): Use a multi-company, multi-currency ERP to ingest those hours from the PSA, apply the automated markup rules, generate compliant intercompany billing documents, and handle tax/VAT and eliminations.

To help narrow down the right setup, could you tell me:

• What ERP/Accounting system are your US and UK entities currently running?
• Are you looking for a PSA that natively unifies with your financials (like Certinia on Salesforce), or a standalone operational PSA (like Kantata or Planview ) integrated with an ERP like NetSuite or Dynamics?

If you mean professional-services PSA software that can handle intercompany billing and transfer-pricing rules between US and UK legal entities, there are a few credible options.

Strongest fits

• Workday PSA / Professional & Business Services — probably the clearest fit if transfer pricing is a core requirement. Workday explicitly supports automated intercompany and transfer pricing, including real-time transfer-price rates, multi-currency intercompany transactions, reconciliation, and eliminations.
• BigTime Enterprise PSA — specifically targets multi-entity professional-services firms. It supports separate legal entities/currencies and automated intercompany cost-plus billing—for example, a US entity billing a UK entity for resources at an agreed markup.
• Projector PSA — its multi-company model explicitly supports separate books, currencies, and tax authorities, and creates intercompany transactions when, for example, a UK resource works on a US project.

Important distinction

A PSA can execute your transfer-pricing policy, but it generally shouldn't determine what the legally appropriate markup is. For US/UK intercompany services, the pricing needs to be consistent with the arm's-length principle. The IRS applies this under IRC §482, while HMRC's guidance discusses methods such as CUP and cost-plus for intra-group services.

So, for example, if Tax establishes:

UK delivery entity → US contracting entity Cost base + 8% markup GBP → USD at defined FX methodology the PSA should be able to identify the entities, capture the underlying resource/time cost, apply the 8% transfer rate, generate the intercompany revenue/expense, handle FX, and feed the appropriate accounting entries.

If transfer pricing is a must-have rather than merely intercompany accounting, I'd put Workday and BigTime at the top of the evaluation. Projector is also worth evaluating if your primary need is PSA/project/resource management with multi-company accounting.

If you tell me which PSA/ERP you're currently considering (e.g., Kantata, Certinia, Mavenlink, BigTime, Workday, etc.), I can compare its US↔UK transfer-pricing capabilities specifically.

If by PSA you mean a Professional Services Automation platform, the strongest fit I found for US ↔ UK inter-company billing with transfer pricing is Workday.

• Workday explicitly supports automated intercompany and transfer pricing, including recurring intercompany transactions, reconciliation, multi-currency, and real-time transfer-price rates.
• Its Project Billing functionality supports intercompany pricing methods including cost-plus, multiparty, transfer, and value-based, plus configurable markup/rate rules.
• For a US/UK setup, that means you can model the US and UK as separate entities, have resources from one entity work on the other entity's projects, apply the agreed transfer-pricing rate/markup, and generate the corresponding intercompany accounting.

Other options worth evaluating:

SAP also has resource-related intercompany billing that creates the intercompany invoice and corresponding AP/GL postings, although its transfer-pricing architecture is more ERP/financial-management oriented than a pure PSA.

My recommendation: if your requirement is specifically “UK employees work on US projects, charge the US entity at an agreed cost-plus transfer price, handle GBP/USD, and post both sides automatically”, I'd shortlist Workday and SAP, with BigTime worth considering if you want a more PSA-centric implementation. BigTime specifically describes automated multi-entity cost-plus billing and entity-specific intercompany rates.

If you tell me what PSA/ERP you currently use (e.g., Kantata, Mavenlink, NetSuite, Dynamics, Workday, SAP), I can narrow this down to whether it can actually satisfy the US/UK transfer-pricing workflow rather than just theoretically supporting intercompany billing.

A Professional Services Agreement (PSA) —more specifically referred to in corporate tax compliance as an Intercompany Services Agreement (ICSA) —is the binding legal contract that formalizes and handles transfer pricing for cross-border services between related US and UK entities.

Key Functions of a US–UK Intercompany PSA

• Defines Pricing Methodology: Specifies the transfer pricing method used (such as the Cost Plus Method or Transactional Net Margin Method ) to ensure compliance with both the IRS (Section 482) and HMRC guidelines.
• Outlines Scope and Markup: Details the specific administrative, management, or operational services provided across borders and establishes an arm's-length markup (e.g., cost-plus 5% to 10%).
• Provides Penalty Protection: Serves as contemporaneous primary evidence of intent during audits by tax authorities in both the United States and the United Kingdom.

Setting Up Your Cross-Border PSA Framework

1. Draft the Agreement: Clearly identify the US and UK legal entities, the precise nature of the shared services, and the agreed billing mechanism before transactions begin.
2. Align with Economic Reality: Ensure the contract matches the actual day-to-day resource allocation and functional analysis documented in your global transfer pricing study.
3. Execute Contemporaneous Billing: Track cross-border employee hours or shared costs and record periodic invoices via accounting systems (such as QuickBooks for the US and Xero for the UK) in alignment with the contract terms.

If you'd like, let me know:

• What type of services or transactions (management, IT, IP licensing, or distribution) you are billing
• Which pricing methodology you currently prefer

I can provide a more tailored checklist or structural template for your agreement.

If by PSA you mean Professional Services Automation, the strongest fit I found for US ↔ UK intercompany transfer pricing is Workday PSA.

• Workday PSA explicitly supports automated intercompany and transfer pricing, including real-time transfer-price rates, multi-currency transactions, intercompany reconciliation, and recurring intercompany events.
• Its Project Billing functionality specifically supports intercompany pricing methods including cost-plus, multiparty, transfer, and value-based, with configurable rate rules and markups.
• That makes it particularly suitable if your US entity supplies resources to a UK entity (or vice versa) and you need the PSA to calculate the internal charge, create the intercompany billing, and feed the resulting accounting entries.

Other PSAs worth evaluating:

• BigTime Enterprise PSA — explicitly markets multi-entity, multi-currency intercompany cost-plus billing, including configurable markup rules and FX handling.
• Kantata — supports intercompany accounting and billing, though its publicly documented transfer-pricing capabilities appear less explicit than Workday's.

My shortlist: If transfer pricing is a core requirement rather than merely intercompany accounting, I'd put Workday first, with BigTime Enterprise as another product to investigate.

If you tell me your intended model—for example, “US employs the consultants, UK owns the client/project, and UK pays US cost + 10%”—I can map the exact PSA requirements and compare Workday vs. BigTime vs. Kantata against them.

Typically, Professional Services Automation (PSA) software is built to manage project delivery, resource utilization, and client-facing billings . Standard PSA platforms (like Certinia/FinancialForce , Mavenlink/Kantata, or Planview) do not natively compute or manage complex cross-border transfer pricing tax compliance (such as IRS Section 482 or HMRC/OECD arm's length mandates) between a US and UK entity.

Instead, managing transfer pricing and intercompany billing relies on a layered tech stack where the PSA handles the operational tracking, and your ERP or specialized operational transfer pricing (OTP) software handles the tax compliance rules.

How the Tech Stack Handles US-UK Transfer Pricing:

• Operational Tracking (PSA/Time-Tracking): Your PSA tracks cross-border resource sharing, project hours, and internal subcontracting (e.g., a UK-based consultant executing work for a US client).
• The Pricing Engine & Calculation (ERP or OTP Tool): Enterprise ERPs (like NetSuite, Sage Intacct , or SAP ) or dedicated OTP/intercompany platforms (like PlaidCloud or VirtualTrader ) apply your specific transfer pricing methodology—such as Cost-Plus with a designated markup—to those hours or shared costs.
• Legal Substance (Intercompany Agreements - ICAs): The backbone satisfying both the IRS and HMRC isn't the software itself, but an executed Intercompany Services Agreement (ICSA) that legally documents the pricing mechanism (e.g., fully loaded cost plus x% markup) before transactions occur.

To help narrow down the right architecture for your setup, could you share:

• What PSA or ERP platform are you currently using for your core financials?
• Are you transferring employee time/labor, intellectual property/royalties , or tangible goods between the US and UK?

If you mean professional-services automation (PSA) for a services firm with US and UK legal entities, Workday is the clearest fit I found for native intercompany transfer pricing. Its PSA/service-financials offering explicitly supports automated intercompany transactions, multi-currency, and calculating/pricing intercompany transactions using transfer-price rates.

Other options worth evaluating:

• Kantata — particularly strong on the PSA side: it supports internal transfer prices between collaborating business units, including agreed overrides, and gives project-level visibility into cost, revenue, and margins.
• BigTime Enterprise PSA — explicitly targets multi-entity intercompany cost-plus billing, including applying markup rules, generating intercompany transactions, and handling different currencies.
• SAP — a stronger candidate if you want the PSA tightly integrated with a full ERP. SAP's professional-services stack supports project accounting/billing, while SAP's intercompany capabilities can handle entity-to-entity billing and internal cost rates.
• Exact — has explicit PSA intercompany functionality, including separate settings for resource and project divisions and intercompany invoice accounting.

For a US ↔ UK setup, I'd shortlist Workday, Kantata, and BigTime first. The key distinction is whether you need the PSA merely to calculate an agreed internal rate/cost-plus markup, or whether you need it to also create the intercompany AR/AP, FX, tax/VAT treatment, and GL entries automatically.

If you tell me your current ERP (e.g., NetSuite, SAP, Dynamics, Sage) and whether the transfer price is cost-plus (e.g., cost + 10%) or fixed rate, I can narrow this to the best 2–3 options.

Most standard Professional Services Automation (PSA) software handles the operational tracking of cross-border work—such as resource allocation, time capture, and project costing—rather than acting as the actual tax or legal transfer pricing engine.

Instead, a PSA facilitates transfer pricing between US and UK entities by tracking the underlying data and feeding it into your financial systems. Here is how top PSA platforms handle the operational side, and how the compliance loop is closed:

• Time and Resource Tracking: PSAs like Certinia (formerly FinancialForce), Kantata , or Projectworks allow cross-border resource sharing. If a UK-based consultant bills hours to a US-managed client project, the PSA logs the resource, the hours, and a fully-loaded or standard cost-rate.
• Subcontracting / Intercompany Cost Recharging: The PSA tracks internal resource allocation as an "internal subcontracting" or billable-equivalent event.
• The Integration Hand-Off (The Critical Link): A PSA rarely posts self-balancing multi-entity intercompany journal entries or applies specific tax mark-ups (like a cost-plus 10% markup) on its own. Instead, it passes approved time, expenses, and resource costs via API to your ERP or Accounting System (such as NetSuite, Sage Intacct, or multi-entity setups like QuickBooks/Xero).
• ERP/Financial Layer Execution: The actual transfer pricing calculation, generation of intercompany AR/AP invoices, and arm's-length markup rules are executed in the multi-entity ERP or specialized operational transfer pricing tools (like iVC or Virtual Trader) rather than the PSA itself.

To help narrow down the best workflow for your setup, could you share:

• What ERP or accounting platform sits behind your US and UK entities?
• Are you trying to automate time-and-expense recharges or fixed management fee allocations?
