Lumanu

Lumanu is a B2B payments solution enabling companies to pay anyone, anywhere, with zero vendor setups and managed compliance and tax. Designed specifically for the marketing and advertising vendor ecosystem, Lumanu is your Payments Master Vendor that works within your ERP/AP system. Pay your marketing and creative service vendors globally without the burden of traditional vendor setup and tax compliance. Lumanu streamlines payments, ensures tax compliance, maximizes financial controls, and manages vendor onboarding for businesses engaging with external partners (influencers, creators, affiliates, agencies, freelancers, production vendors, etc.). Positioned within the B2B payments software category, Lumanu is purpose-built for finance, procurement, and operations teams at enterprises, agencies, and platforms who manage payments to a large number of external partners. Lumanu consolidates fragmented payment, compliance, and onboarding workflows into a single vendor relationship within a client’s AP or ERP system. Clients fund Lumanu once, and Lumanu acts as the vendor of record, handling all downstream tasks, including identity verification, vendor onboarding, global disbursements, and tax documentation across 200+ countries.

It replaces the need for clients to individually manage thousands of one-time or short-term marketing vendors with a scalable, compliant infrastructure purpose-built for distributed vendor ecosystems. Key features include: • Vendor Onboarding & Compliance • KYC/KYB, W8/W9 tax form collection, AML/OFAC/PEP screening • Business and bank account verification • Global Payments • Local payment rails (ACH, SEPA, Visa Direct), Swift, and card payments • Local currency disbursement in over 200 countries • Tax Compliance • IRS 1099 reporting, VAT/GST calculations, e-invoicing • Auto tax withholding and invoice generation • Financial Controls • Segregated Workspaces and Wallets • Approval workflows, custom roles, audit logs • Vendor Experience • Self-serve portal, real-time payment tracking, Instant Pay • Dedicated support for vendors worldwide Lumanu is designed to serve the needs of global brands, agencies, and platforms that require robust control, scale, and compliance in marketing-related payments.
