10 common mistakes when opening a business in Guatemala (and how to avoid them)

We’ve watched hundreds of businesses through their first months of operation. Some grow, some close. The causes are many, but certain mistakes repeat again and again. Here are the 10 most common — and what to do instead.

1. Not separating personal finances from the business

The most common mistake. Early on it feels natural to put everything in one account. Three months later you don’t know how much you earned, how much you spent, or whether the business is profitable. Open a business account in the first week — even a checking account at the same bank.

2. Taking cash only

You lose half your potential sales. Accepting card or transfer today is trivial — a processor at a 3% fee pays you back 10× more in extra sales than it charges in fees.

3. Not issuing electronic invoices (FEL)

The SAT eventually comes knocking. And when it does, the fines are far higher than the cost of having operated properly from the start. Getting enabled as a FEL issuer is free, and issuing from the SAT’s Agencia Virtual or App FEL has no cost either. There’s no excuse not to do it.

4. Underestimating fixed costs

Rent, water, electricity, internet, salaries — costs you pay whether or not you’re selling. Calculate them before you open and multiply by 3 for the first months (they always cost more than you expect). If you don’t have 3 months of fixed costs in reserve when you open, open later.

5. Hiring before cash flow is steady

The initial excitement pushes you to hire 3 people in the first month. If sales aren’t confirmed, you’ll be paying salaries out of your personal reserve. Wait at least 60–90 days of steady cash flow before your first hire.

6. Not tracking inventory

If you sell products, you have to know what you have and what you don’t. Without digital inventory, you’ll sell what you don’t have (angry customer) or hold stock that expires in the back room (direct loss). Cuadra, Excel, or a notebook all work — the problem is having none.

7. Measuring nothing

How much did you sell yesterday? What was your average ticket last month? Which product sells most? If you don’t know, you’re operating blind. Most small businesses don’t need complex reports — they need 3 key numbers: sales/day, average ticket, and gross margin.

8. Over-investing in looks before validating

Spaces decorated like a Pinterest board but with zero customers. Investing in infrastructure is only justified once you’ve validated that the offer works. Start simple, validate demand, then invest.

9. Not documenting processes

When you hire your first person, everything you know "lives in your head." Document the basic processes from the start — a Google Doc with "how to open the register," "how to close the day," "how to issue an invoice" saves you months of re-explaining the same thing.

10. Not asking for help

The last and most underrated. There are entrepreneur networks in Guatemala (AGER, chamber-of-commerce programs, WhatsApp communities) that share mistakes and lessons. Spending 6 months making mistakes someone already made is a waste of time and money.

You don’t have to make every mistake yourself. Learn from the ones who came before you.
