ERP Consultant in London

London's business landscape and what it asks of an ERP

London's economy leans heavily on services. The City and Canary Wharf hold banks, insurers, brokers and asset managers. Around them sit some of the largest law, accountancy and consulting practices anywhere, plus a dense layer of advertising, media and creative agencies. Shoreditch, King's Cross and other districts host fintech, software and marketplace companies at every stage. And many international groups choose London as their head office, running subsidiaries across Europe, the Gulf, Africa and Asia from here.

These businesses rarely struggle with basic bookkeeping. Their problems appear at the edges: billing arrangements that the system cannot represent, product data that will not reconcile to the ledger, or a group close assembled by hand from subsidiaries on different software. Those are design problems, and they need to be solved before configuration starts.

My UK ERP consultant page covers the national topics, including VAT, Making Tax Digital and data protection. Here I focus on the London-specific patterns: practice finance, fintech data volumes and multi-country groups. For a wider view of how I work with British companies, see the UK overview.

Partner-led firms: engagements, lock-up and profitability

A London law, accountancy or consulting firm earns money through engagements, so its ERP or practice management system must follow each engagement from proposal and conflict checks through time recording, billing, collection and write-off. Partners watch lock-up, the time between doing work and getting paid, as closely as revenue. They also want profitability by client, sector and partner, which depends on how cost and time are allocated.

The requirements here are detailed. Fee arrangements might be hourly, fixed, capped, staged or success-based, sometimes within the same client. Disbursements and third-party costs pass through with or without markup. Billing often needs partner review, and some clients insist on their own invoice formats or e-billing portals. The checklists I capture this with are set out on my professional services ERP and consulting firm ERP pages.

The key design decision is often whether a general ERP should handle practice management at all, or whether a specialist practice system should run engagements while the ERP handles finance. I compare both routes honestly, with the integration effort each one implies, and document the decision so the firm's management committee can sign it off.

Fintech and SaaS scale-ups: from product data to a clean ledger

London's fintech and software companies often outgrow their first accounting setup within a few funding rounds. The product platform records payments, loans, trades or subscriptions in volumes no finance team can post one by one, and the general ledger falls behind the business it is meant to describe.

I approach this as a data architecture question. Which events in the product ledger matter to finance? How should they be summarized into daily or periodic journals? Which balances must reconcile every day, such as cash at payment providers and customer balances, and who investigates breaks? For regulated firms, records that relate to client money or safeguarding usually live in the product or specialist systems, and your compliance team will set expectations for record-keeping, outsourcing and hosting that the ERP and its vendor must meet.

For subscription businesses the focus shifts to billing: plan changes, usage charges, multi-currency pricing, credit notes and revenue recognition. I set out these rules using my SaaS ERP framework and plan the connections through system integration work, so finance closes from system data rather than exports pasted into spreadsheets.

International groups with a London head office

When a group runs subsidiaries in several countries from London, each subsidiary keeps books in its local currency, under local statutory and tax requirements, often on software chosen locally years ago. Head office then has to consolidate, translate currencies, eliminate intercompany balances and report to the board, lenders or a parent company abroad.

There are a few ways to fix this, and the right one depends on your group. Some move every subsidiary onto one ERP with a shared chart of accounts and local localization where it is available. Others keep local systems and introduce a consolidation layer that maps each local chart to a group chart. Many end up with a hybrid: one ERP for the larger entities and mapped imports for small ones. I compare these options, including what each platform offers for local tax and statutory needs in the countries you operate in, which should always be checked with local advisors.

Intercompany is usually where groups feel most pain. Management charges, shared service recharges and cross-border sales need to be invoiced consistently and agreed on both sides before the close. I define these flows with your finance team, then test them end to end through ERP solution design and structured UAT.

Remote delivery on London hours

India sits a few hours ahead of London, so my working afternoon covers your morning. That makes London one of the easiest cities for me to support remotely: workshops, design reviews and training sessions can all happen in normal London business hours, and the window grows a little during British Summer Time. Groups with finance teams in the Gulf or continental Europe can usually join the same calls without anyone working late.

Between sessions, I send written decisions, updated process maps and short recorded explanations, so stakeholders who missed a meeting can catch up without another one being booked. For month-end testing and go-live, I schedule extra availability around your close calendar.

If an in-person session would genuinely help, such as a partner workshop or a board presentation, it can be arranged ahead of time. Otherwise everything runs online. To discuss a system decision for a London firm or group, get in touch.
