Hey Product Hunt! 👋 I'm Manuel, founder of BlackHold Consulting and builder of Clientum. The problem I kept seeing with every SMB client I consulted: they were running their business across 4-5 disconnected tools — one for invoicing, another for clients, a spreadsheet for cash flow, something else for HR. Every month, hours lost just stitching things together. So I built Clientum: a single platform that connects invoicing, treasury, CRM, HR, inventory and accounting. No integrations needed. No data scattered everywhere. We're a small team from Galicia, Spain, and this is our first PH launch. Would love your honest feedback — what would make this a must-have for your business or your clients? Happy to answer every question. 🙌

One thing I learned while working with small businesses: Most founders don’t have a “management” problem. They have a fragmentation problem. Invoices in one tool. Clients in another. Cash flow in a spreadsheet. HR somewhere else. Clientum was built to reduce that noise and give SMBs one clear place to run the business💥
