𝗢𝗽𝘁𝗶𝗺𝗶𝘇𝗲𝗱 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻𝘀 + 𝗖𝗹𝗲𝗮𝗻 𝗕𝗼𝗼𝗸𝘀 = 𝗛𝗶𝗴𝗵𝗲𝗿 𝗣𝗿𝗼𝗳𝗶𝘁𝘀 If your books are behind, your reports don't make sense or you're not really sure where your money is going, you're not alone. That's exactly the kind of situation I sort out for business owners every day. I've spent 17 years doing this work and the clients who get the most out of working with me are the ones who are tired of guessing. They want clean numbers, clear reports and a business that doesn't fall apart the moment they step away. QuickBooks Online is my expertise, whether you need a full year of cleanup, a migration from Xero or Wave, a fresh setup from scratch or just someone reliable handling it every month, I've done it all. I can also manage your Gusto payroll end-to-end and work hand-in-hand with CPAs when tax season comes around, so nothing slips through. The operations piece is what sets me apart from most bookkeepers. I don't just fix your numbers, I build the systems around them so your business can actually run without you being in every conversation. SOPs, onboarding flows, automations, delegation frameworks, I document and set up the stuff that's currently living in your head. What I can help you with: ✅ QuickBooks Online: Setup, Complete Cleanup & Full Cycle Bookkeeping Your QBO is a mess, years behind or was set up wrong from the start? I'll fix it and keep it clean going forward. ✅ Migration to QuickBooks Online Moving from Xero, Wave or spreadsheets; I handle the full transition without losing your data or history. ✅ Monthly P&L, Balance Sheet & Cash Flow Reports You shouldn't be running blind. I deliver clean, customized reports every month so you always know where you stand. ✅ Budget vs. Actuals Reporting See exactly where you're over or under budget, so you can make adjustments before small variances become big problems. ✅ Cash Flow Forecasting Reports Stop being surprised by slow months. I build forward-looking cash flow reports so you can plan ahead with confidence. ✅ Job & Project Profitability Reports Not sure which clients or projects are actually making you money? I break it down so you can double down on what works. ✅ Year End & Tax Ready Reports No more scrambling in Q1. I keep your books CPA ready all year so tax season is just another month. ✅ Gusto Payroll: Processing & Compliance W2s, 1099s, filings, tax deposits, handled correctly and on time, every time. ✅ Accounts Receivable & Payable Management Chasing invoices and losing track of what's owed? I put a system in place so nothing falls through the cracks. ✅ Account Reconciliation Bank, credit card, merchant accounts, all reconciled and accurate so your reports actually reflect reality. ✅ SOPs, Workflow Systems & Automation If your team relies on you for everything, that's a systems problem. I document processes and set up automations so they don't have to. ✅ Team Onboarding & Delegation Frameworks Scaling but can't let go? I build the training and handoff systems that make delegation actually work. Platforms: QuickBooks Online · Gusto · Xero (migration) · Wave (migration) · Google Sheets · Stripe · PayPal · Square Results I've delivered: 🔴 99.9% reconciliation accuracy, consistently 🔴 $150K+ in missed income recovered through audit corrections 🔴 35% reduction in overdue receivables 🔴 100% payroll compliance, no late filings, no penalties 🔴 60+ hours/month saved through streamlined workflows 🔴 $500K+ in retained revenue through process improvements 🔴 40% faster client onboarding after SOP implementation If you're tired of not knowing your numbers or knowing them but not having the time to fix them, let's talk. Send me a message and we'll figure out exactly where to start. 📩

I've managed and executed advertising campaigns for Microsoft, LinkedIn, Rakuten, Ad Council, Macy's, Burger King, and Mercedes from strategy to implementation. I'm especially adept at targeting LinkedIn, Google/YouTube, and Facebook/Intagram users to ensure you are hitting the ideal target audience for your marketing efforts. I also know how to set up conversion tracking and re-marketing campaigns so you can re-target users who are engaged in your content. I have a wide range of experiences working at a media agency, a publisher, and a video ad server. I've worked with various brands and industries and am passionate about talking strategy and execution to get the most out of your objectives. I am very transparent in my work and like to think of myself as a partner and extension of your team. Together we'll develop high-quality multi-channel marketing strategies to solve your business problems!

Having Adam in a meeting means you will quickly identify the ask, proposed solution, and plan, making each meeting efficient for everyone involved. Adam's clarity, speed, and depth of knowledge separate him from the rest. I'm convinced Adam does not have bad days.” - Director of Marketing @ Reddit ⭐️⭐️⭐️⭐️⭐️ “Adam Yaeger and his team, Llama Lead Gen is an incredible asset to our Ad Council team. Adam was super reliable and always there to answer our questions throughout the process. They are incredibly savvy in managing our campaigns from start to finish. They were our teammates through and through. I'm looking forward to working together with Adam in the future.” - VP of Media @ Ad Council ⭐️⭐️⭐️⭐️⭐️ “What can I possibly say about Adam to do this justice? He's done everything from building out our ad campaigns, creating landing pages, scheduling organic social media posts, joining potential client calls, and collaborating with multiple team members as if he's fully integrated into the company. It's been a wonderful experience; he's impressed on every level. And this is coming from someone who has worked with WAY too many people on the marketing front and has always been disappointed in one way or another. Anyone hiring Adam is in amazing hands. Can't promise I won't keep him very busy, though, and limit his free time for other projects :)” - Founder & CEO @ Digital Marketing Agency ⭐️⭐️⭐️⭐️⭐️
