The Silent Killer of SMB Acquisitions? The “90 day cash crunch”. And the worst part is most buyers don’t even recognize that it’s going to happen. All throughout the buying process, the entrepreneur is focused on understanding the systems, roles, and growth opportunities of the business. They’re focused on getting the lender, investors, and sellers on board with the process. And they miss one of the most critical concepts in operating a business: cash flow
Until you’re in the business, it all looks clean on a spreadsheet: monthly earnings = cash flow. But it doesn’t exactly work like that in the real world.
To help you avoid making these critical mistakes, we enlisted help from Reid Tileston. Reid is an amazing educational resource, offering both real-world and academic perspectives that have educated thousands in the ETA community. We’d highly recommend checking out Reid’s information on his website and following him below. He also has a great book about entrepreneurship called Grit it Done.

Most underrated diligence item in SMB acquisitions?
Cash flow dynamics.
When you’re buying with debt (a lot of it), you better understand how cash actually moves. Meaning purchasing cycles, invoice timing, collections, payments.

What is the “90-day cash crunch”? Put simply, the 90-day cash crunch refers to the business running out of cash within the first 90-days. Now, it might seem like quite a daunting task to tank a business so quickly to end up without liquidity in something as little at 90 days, but it happens more often than it might seem. Though we do not contemplate a cash crunch beyond the 90-day period in this article, many of these concepts can be applied to any stage of operating a business. Understanding the root causes outlined here is a great start to mitigating future cash flow issues. At the end of the day, the entire Entrepreneurship Through Acquisition (“ETA”) concept relies on two fundamental concepts: 1) an effective acquisition, and 2) effective operations. One without the other leads to failure (most of the time).
For the acquisition, the buyer (who often is a first-time buyer in SBA funded ETA deals) could make an incorrect analysis of sufficient working capital. In one scenario the buyer under-negotiates working capital because it was the only way to get the deal done. In another similar, but related example, Buyers often choose to maximize post-close ownership rather than post-close liquidity leaving little in the way of excess cash to float for any unforeseen cashflow issues. Lastly, the Buyer did not fully understand the ramifications of not asking for a line of credit (“LoC”) from their lender. Though this happens less frequently than it used to, there are still Buyers out there who do not have an LoC available for additional liquidity. And worse, some banks don’t even offer them! Lastly, in SBA transaction escrows and holdbacks are frowned upon thus a working capital true-up ends up changing the Seller note that isn’t paid until years down the road; but you need cash now!
On the operations side is where it gets more difficult. Employees can leave when they find out the owner sold the business. They might just march into the new owner’s office to ask for a raise or a bonus— and if they don’t get paid they walk. The #1 customer the Seller’s known for 15 years decided to go with another service provider since his relationship left. Not to mention this is all happening while the new owner’s learning a new business in an industry they (likely) haven’t worked in before.
One thing is guaranteed in small business— expect the unexpected. There are hidden costs in any transition and for that reason… Cash is King, especially in your first 90 days.
Employees demanding a raise, a bank that won’t accept deposits, vendors won’t give payment terms, and a few checks got lost in the Seller’s P.O. box. Sounds like quite a nightmare in the first 90 days— one that very well could sink the ship without preparation. Liquidity at closing isn’t just a financial concept-- it is an insurance policy against the 90-day cash crunch and potentially personal bankruptcy. It’s your get-out-of-jail free card when something unexpected (edit: guaranteed) happens. And it’s what gives a new owner room to learn, adapt, and operate without making panicked decisions that end up creating long-term consequences.
Let’s break it down:
● You need real cash on the balance sheet. Ideally, you walk into ownership with cash on the balance sheet and a line of credit in place. Now how much cash is a different, more nuanced question that depends on the company’s cash conversion cycle and working capital intensity. The way we like to think about it is in X days of operating expenses and/or monthly sources and uses from working capital swings. The line of credit can be a difference maker when selecting lenders for a deal; you might have to make a tough decision on which bank to select depending on the availability of a line of credit or not. (Tip: contact [email protected] for help with your SBA financing needs)
Use it strategically. The quality of earnings provider will advise on the amount of cash to put on the balance sheet. And many readers may have thought of using it for new uniforms, a new website, or a new marketing campaign (the broker told you they’ve never marketed before, and it’s a huge growth opportunity). But that cash buffer isn’t there for major capital investments. It’s there so when the business is in a tight spot with the hidden costs of the transition, it will still able to make it through to the other side.
Some transition costs are unavoidable. Even at the highest levels of mergers and acquisitions in private equity, big law, investment banking, etc. there are surprises and things that go wrong. Smart operators plan for them by having access to quick cash whether it be through a LoC or a family member invested in their success who can write an emergency check upon request.
Lastly, it buys you time. Often it is the case that the business will get worse before it gets better. Cash on the balance sheet and a strong line of credit do exactly that. They mean owners can slow down, make thoughtful, long-term decisions for the Company, and avoid the desperate 90-day cash crunch that takes too many first-time buyers down.
Bottom line? If you’re squeezing every dollar to maximize post-close ownership, but leave yourself with no room for error, you’ve already made the first critical mistake. That doesn’t mean the deal has to be overcapitalized, but that does mean Buyers need to bring enough cash to the balance sheet and sign with a bank that will underwrite a line of credit.
