Case Study: Pierre Tunger achieves streamlined invoicing and all-in-one billing with Zervant

Pierre Tunger - Customer Case Study

Pierre Tunger is a freelance business consultant who helps sole traders and start-ups get a grip on the numbers—sales forecasts, budgeting, cash flow, pricing and cost planning. He found many entrepreneurs struggle with financial planning and fragmented tools, which can leave viable businesses unfunded or unprofitable without clear, objective forecasts.

Pierre delivers Excel-based models and no‑obligation consultations to identify viability, produces turnkey calculations and plans, and helps clients apply for grants. By vetting projects early and using Zervant’s all-in-one invoicing, he streamlines billing and administration; most clients secure funding or leave with clear, actionable plans, and Pierre has grown a successful, efficient consultancy.
