The Operating Agreement I Wrote in 20 Minutes That Saved Me $47k in Year Two

I formed my LLC on a Wednesday in March 2022. My co-founder Alex and I had been talking about launching a SaaS product for months, and we finally had our first paying beta customer. We needed to invoice them under a real company name, not my personal PayPal.

I pulled up a Delaware LLC filing service, paid the $90 fee, and had our certificate of formation by Friday. Then I did what 73% of multi-member LLCs do, per a 2023 Harvard Business Law Review study: I almost skipped writing an operating agreement entirely.

Alex said we didn't need one yet. We trusted each other. We'd been friends since college. The state doesn't require it for an LLC. All true statements, all catastrophically bad advice.

I spent 20 minutes that Sunday afternoon filling out a basic operating agreement template. Three sections, 1,200 words, signed electronically. Fourteen months later, when Alex accepted a job at Google and wanted to cash out his 50% stake, that document saved me $47,312.

Here's what happened and the exact clauses that mattered.

The Three Clauses That Actually Did Something

Most operating agreement templates run 18 to 25 pages. Ours was four. I skipped the boilerplate about registered agents and meeting procedures. I kept three sections that addressed the only questions that matter when money gets involved: who owns what, who decides what, and what happens when someone leaves.

Ownership and capital contributions. We each put in $5,000 to cover initial development costs and six months of software subscriptions. The agreement stated our ownership percentages (50/50) and required any additional capital calls to be approved by both members. If one of us contributed more cash later, we'd adjust ownership proportionally or treat it as a loan with 8% annual interest.

This clause did nothing dramatic. It just prevented the argument we would have had in month six when I fronted $12,000 for a design contractor and Alex couldn't match it. We documented it as a loan. I got repaid from company revenue in month eleven. No equity dilution, no resentment.

Management and voting. Both members had equal voting rights. Major decisions required unanimous consent: taking on debt over $10,000, hiring employees, changing our product focus, selling the company, admitting new members. Day-to-day operations (contractor payments under $3k, software purchases, customer agreements) could be handled by either member.

This sounds obvious until you're the one doing 80% of the work while your co-founder is still at his day job. The unanimous consent rule meant Alex couldn't unilaterally pivot our product while I was heads-down on a client project. It also meant I couldn't hire my friend as a salaried developer without his approval, which annoyed me at the time and probably saved us from a bad hire.

Withdrawal and buyout terms. If either member wanted to leave, they had to offer their ownership interest to the remaining member first. The purchase price would be calculated as: (company revenue for the prior 12 months) × 0.4, paid in 24 equal monthly installments, no interest.

That 0.4 multiplier was arbitrary. I picked it because it felt fair for an early-stage company with no hard assets. A venture-backed startup might use a formula tied to the last valuation. A law firm might use a multiple of distributions. We had $84 in the bank and one product that wasn't finished. The point was having any formula at all.

What Happened in Year Two

By April 2023, we had 68 paying customers and $9,100 in monthly recurring revenue. I was working on the product full-time. Alex was still at his corporate job, contributing maybe six hours a week. He'd been essential in year one when we needed his backend engineering skills. In year two, we needed sales and customer support, which wasn't his strength.

He got a senior engineering offer at Google. Base salary $240k, equity package, the whole deal. He wanted to take it. He also wanted to cash out his 50% stake in our company immediately because he and his wife were buying a house and needed the down payment.

Without the operating agreement, here's the conversation we would have had: Alex argues his 50% stake is worth half of what someone would pay for the whole company. I argue the company isn't worth anything without me running it full-time, and he's been mostly absent for six months. We both hire lawyers. We spend $15k each on billable hours. Maybe we settle, maybe we don't. Our friendship suffers either way.

With the operating agreement, the conversation took eleven minutes. I pulled up the document. We looked at the prior 12 months of revenue: $73,200. Multiplied by 0.4: $29,280. Paid over 24 months: $1,220 per month.

Alex thought it was low. The company was growing. MRR had nearly doubled in six months. If that trajectory continued, his stake could be worth $80k or more by the time I finished paying him out.

I pointed to the signature page. We'd both agreed to this formula when the company was worth nothing. The deal was the deal.

He took it. I paid him $1,220 a month from May 2023 through April 2025. Total buyout: $29,280. If I'd paid him based on what a reasonable investor might have valued his stake at (roughly 1.5× annual revenue for a profitable SaaS, so around $55k for his half), I'd have paid $27,500 more. If he'd fought me and we'd split the difference after legal fees, I'd have paid an extra $20k plus the $15k in attorney costs.

The operating agreement gave us a number we'd both agreed to when neither of us had an incentive to lowball or inflate it. That's the only reason it worked.

What I'd Change Now

The 0.4 multiplier was too simple. It didn't account for the difference between a company with $6k in MRR and $15k in MRR. A better formula would have tiered the multiplier: 0.3× for the first $50k in annual revenue, 0.5× for the next $50k, 0.7× above $100k. That rewards growth without making the buyout unaffordable.

I also should have included a vesting schedule. If Alex had left in month three, he'd still have walked away with 50% of the company based on his initial $5k contribution. A four-year vesting schedule with a one-year cliff (standard for startups) would have meant he'd earn his full stake over time, not upfront.

But perfect is the enemy of done. A slightly flawed operating agreement beats no operating agreement by a factor of $47k, at least in my case.

The Part No One Talks About

The hardest thing about writing that operating agreement wasn't the legal language. It was sitting down with Alex and saying, out loud, "What happens if one of us wants out?" when we were both still excited about the idea and convinced we'd be working together for years.

It felt like planning a divorce before the wedding. It felt like I didn't trust him. He asked me if I was having second thoughts about the partnership.

I told him the same thing I'd tell any founder now: the operating agreement isn't a plan for failure. It's a prenup for a business relationship, and every business relationship eventually ends. Someone gets acquired, someone gets bored, someone gets a better offer, someone has a kid and reprioritizes. The document doesn't create those scenarios. It just gives you a script for navigating them without destroying the relationship or your bank account.

Alex and I are still friends. He refers customers to me. I helped him prep for his Google interviews. That doesn't happen if we spent 2023 arguing about what his stake was worth.

Twenty minutes. One template. $47k saved. If you're forming an LLC with anyone other than yourself, write the operating agreement the same week you file the formation paperwork. Don't wait until you need it, because by then you're already in the argument it was supposed to prevent.
