Lumanu

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.

Merze

Merze (www.merze.ai) offers cross-border US tax intelligence for global founders. We unify GAAP bookkeeping, corporate tax filing, sales tax nexus monitoring, and entity compliance into one secure platform for high-growth startups. Merze eliminates these risks by unifying all six layers of compliance into one dashboard. The Solution: Six Unified Services Merze provides complete coverage through six integrated pillars. 1. US Business Incorporation Merze handles the structural foundation of your company. Whether you are forming a Delaware C-Corp for venture capital or an LLC for pass-through taxation, we manage the filing, EIN acquisition, and post-incorporation documents. We ensure your entity structure aligns with your fundraising goals from day one. 2. GAAP Bookkeeping & Financial Reporting Investors do not accept cash-basis spreadsheets; they demand GAAP (Generally Accepted Accounting Principles) financials. Merze maintains your books on an accrual basis every month. Our HITL CPAs reconcile your bank feeds, categorize expenses, and generate investor-ready P&L, Balance Sheet, and Cash Flow statements. This ensures you are always ready for a board meeting or Series A due diligence. 3. Corporate & Personal Income Tax Filing We handle the complete lifecycle of income tax compliance. This includes: - Federal Form 1120: Annual corporate income tax return. - State Income Tax: Filings for every state where you have physical or economic presence. - Founder Compliance: Personal tax filings for founders to ensure alignment between personal and business assets. 4. Sales Tax Nexus Monitoring State-level tracking is no longer enough. Following the Wayfair ruling, startups can trigger "Economic Nexus" merely by selling software or goods into a jurisdiction. Merze tracks your liability across 50 states and 11,000+ local tax jurisdictions (cities and counties). We calculate the exact tax owed and file the returns automatically. 5. Registered Agent Services Every US entity is legally required to have a Registered Agent to receive government notices. Merze acts as your official presence in every state where you operate. We receive, digitize, and alert you to legal notices in real-time, ensuring your corporate veil remains intact and your entity stays in good standing. 6. 1099 Vendor Management End-to-end automation for vendor qualification and 1099-NEC filing, including free CPA verification to ensure you pay only for eligible vendors, not blind bulk uploads.
