[Hiring] Client-Facing Financial Controller @JobRack

Role Description

We're looking for a Client-Facing Financial Controller to own the day-to-day finance function for a portfolio of ambitious founder-led ecommerce companies and thrive on the intensity of that work. This is a hands-on delivery role, not an oversight role.

• Run end-to-end finance for a portfolio of founder-led ecommerce clients: month-end close, management accounts, cashflow, reporting and ad-hoc analysis.
• Deliver month-end close within 10 working days for every client, including full balance sheet reconciliations signed off to source.
• Review day-to-day finance operations across your portfolio and raise the bar on accuracy and timeliness.
• Oversee supplier payment runs and ensure cash is going out cleanly, on time and properly approved.
• Maintain granular weekly cashflow forecasts so founders know exactly where they stand.
• Own multi-channel revenue reconciliation using A2X or Link My Books (Shopify primary, Amazon and other marketplaces where relevant).
• Reconcile payment processor payouts (Stripe, Klarna, PayPal, Shopify Payments) including fees, FX, refunds and chargebacks.
• Handle inventory and COGS accounting: landed cost, stock adjustments, margin analysis, 3PL reconciliations.
• Lead weekly and monthly client calls: walking founders through their numbers, answering questions on the fly, flagging risks and opportunities.
• Manage and mentor Finance Managers working on your clients, reviewing their work and raising the bar.
• Build and refine reporting packs, KPI dashboards and cashflow models that clients actually use.
• Continuously improve the playbook: better processes, smarter tooling, AI-assisted workflows.

A typical week includes multiple client touchpoints, reviewing finance operations across your portfolio, overseeing supplier payment runs, updating granular weekly cashflows, 3 to 5 reporting packs out the door, and time spent making the machine run smoother for next month.

This is a full-time role with flexible hours, but most of our clients work on UK (GMT+1) or New York (GMT-4) time, so expect meaningful overlap with those windows.

Qualifications

• Strong technical accounting: you can run a clean close, own balance sheet reconciliations end to end, and reconcile back to source in every account.
• Proven track record of closing books within tight timelines (ideally 10 working days or better) across multiple entities.
• ACCA, CIMA, CPA or equivalent qualification.
• 3+ years owning end-to-end finance for multiple clients or business units simultaneously.
• Hands-on ecommerce accounting experience: Shopify (and ideally Amazon), A2X or Link My Books, multi-channel revenue recognition, COGS.
• Proven ability to reconcile payment processors (Stripe, Klarna, PayPal, Shopify Payments) including fees, FX and chargebacks.
• Advanced Xero: clean setup of tracking categories, bank rules, reporting layouts and consolidations.
• Strong Excel or Google Sheets skills; you can build a model, not just read one.
• Confident on client calls; you can walk a non-finance founder through their numbers and earn their trust.

Requirements

• Experience at a multi-client accounting firm or fractional CFO practice.
• Inventory-heavy ecommerce experience: 3PL reconciliations, landed cost, stock counts, multi-warehouse.
• Familiarity with AI tools (Claude, ChatGPT, Gemini) to speed up day-to-day work.
• Past experience mentoring or managing junior finance team members.

Benefits

• £4,000–£5,000/month depending on experience.
• Full-time, fully remote.
• 25 days paid holiday.
• 10 days paid sick leave.
• Local public holidays off.
• Your birthday off.
• Annual bonus based on individual and company performance.
