Entrepreneurs in Colombia: The Most Common Mistakes of the First Year

I opened my first business in Bogotá with COP 15 million in capital, a business name, and zero registration at the Chamber of Commerce. Six months later, a large company wanted to hire me, they asked for my NIT, and I had nothing to show them. I lost the contract. It was the first of many expensive lessons.

The first year as an entrepreneur in Colombia is a minefield. Not because entrepreneurship here is impossible — on the contrary, there are real opportunities — but because the formal system has its own rules and nobody explains them to you beforehand. Chambers of commerce offer courses, but they're generic. Accountants charge you to answer questions. And Facebook groups are full of contradictory advice. If you're just starting out and want to begin getting clients without relying only on referrals, you can post your services for free on Colombia Move and have a public page with WhatsApp contact from day one.

After talking with dozens of Colombian and foreign entrepreneurs who have been operating for more than a year — from clothing stores in downtown Medellín to digital agencies in Chapinero — these are the seven mistakes that come up again and again. If you can avoid them, you're already one step ahead of most.

Error #1: Starting to invoice without formalizing the business

The most common and most costly mistake in the long run. Many entrepreneurs start providing services or selling products without registering at the Chamber of Commerce, without an active RUT, and without thinking about the legal entity they're going to use.

The consequence isn't immediate — at first, everything seems to work. But when a corporate client arrives (who will ask you for a NIT to make a withholding), when you want to open a business bank account, or when you need to formally hire someone, you realize you built on sand.

The formalization process isn't as complicated as it seems. For most individual entrepreneurs, the route is: activate your RUT at DIAN as a natural person, register at the Chamber of Commerce as a commercial establishment if you have a physical location, and decide if you need to incorporate a SAS. A SAS makes sense if you're going to have partners, need to separate personal assets from business assets, or plan to grow quickly. If it's just you, being a natural person may be enough for now.

Error /#2: Ignoring electronic invoicing until DIAN blocks you

Since 2019, Colombia has one of the most demanding electronic invoicing systems in Latin America. If you exceed COP 12 million annually in income — which happens pretty quickly — you're required to issue electronic invoices transmitted to DIAN in real time. A PDF receipt via WhatsApp doesn't count as a legal invoice.

The problem is that many entrepreneurs know about the requirement but postpone it. Until an important client asks them for a valid invoice, or until DIAN sends them a notice. At that point, they already have months of operation without complying with the regulation, and there's no way to regularize it retroactively.

The good news: there are free options. DIAN offers its own Free Electronic Invoicing portal. The interface isn't pretty, but it works for those who invoice infrequently. If you already have a reasonable volume, platforms like Alegra (from COP 50,000/month) or Siigo make the process much smoother and integrate with your accounting.

Important: before issuing your first electronic invoice, DIAN must formally enable you through a testing process. Plan a week for that procedure. Don't leave it for the day an urgent client asks you for an invoice.

Error #3: Not understanding what taxes you need to pay — and when

The Colombian tax system has several taxes that apply to businesses, and confusing them is very easy at first. The three that most affect the newly formalized entrepreneur are:

Withholding tax: when you invoice a company (not natural persons), the client is obligated to withhold a percentage of the invoice from you (typically 3.5% or 10% depending on the concept) and pay it directly to DIAN. It's not that they're stealing from you — it's a prepayment of your income tax. Always ask for the withholding certificate at year-end to claim it in your tax return.

VAT: if you're responsible for VAT (you exceeded the threshold of 3,500 UVT in annual income, approximately COP 183 million), you must charge 19% VAT to your clients and declare it bimonthly. Most new entrepreneurs are in the simple or simplified regime and don't charge VAT directly, but it's worth confirming with an accountant.

Industry and commerce tax (ICA): it's the municipal tax. Each city has its own rate. In Bogotá it can be between 0.3% and 1.4% of gross income, depending on the sector. In Medellín it's similar. It's declared annually at the respective municipal office.

Error /#4: Hiring employees without knowing labor law

Hiring your first person seems simple: "I'll pay you X per month and we'll start". But in Colombia, the real cost of a formal employee goes well above the agreed salary.

Colombian salaries must include: social security (health + pension, where the employer pays 12.5% and the employee pays 9%), parafiscals (SENA, ICBF, Compensation Fund — another 9% of salary), service bonus (an extra salary per year, paid in two installments), severance (an annual salary that goes to a fund), and vacation (15 business days per year).

In practice, if you hire someone at COP 1,600,000 (2026 minimum wage), the real cost for your company is between COP 2,200,000 and COP 2,400,000 monthly. For an employee with a salary of COP 3,000,000, the total cost can exceed COP 4,200,000.

The mistake isn't hiring — the mistake is not calculating this beforehand and discovering halfway through the year that the business can't sustain the payroll. If you can't afford a formal employee, consider hiring by service provision (civil contract) with an independent contractor who is already formalized. It's a valid option for one-off or specialized work.

The guide to Colombian labor law for entrepreneurs and employers explains contracts, settlements, and employee rights in more detail.

Error /#5: Mixing personal finances with business finances

It sounds like textbook advice, but it's one of the most frequent problems. Many entrepreneurs have a single personal bank account and from there they pay business expenses, receive client payments, and also cover monthly groceries and rent.

The result is an accounting disaster. You can't really know if the business is profitable because you don't have clear visibility of its income and expenses. When tax filing arrives, your accountant has to review transaction by transaction. And if you ever need to demonstrate the financial health of the business to a bank or investor, you have nothing coherent to show.

Practical solution: open a savings account dedicated exclusively to the business from the first month. Nequi Business, Bancolombia or Davivienda have options for small businesses. Pay yourself a fixed monthly 'salary' from the business — what's left as your personal income — and separate the rest for operating expenses, taxes and reserves.

Error #6: Underestimating working capital

Working capital is the money you need to operate while you wait for customers to pay you. It's the Achilles heel of many businesses that, in theory, are profitable but die from cash flow problems.

Real example: you have a COP 20 million contract with a mid-sized company. They ask for 60 days of credit to pay. Meanwhile, you have to pay payroll, office rent, suppliers and your own expenses. If you don't have a cash reserve to cover those two months, you're in trouble — even if the business is 'successful' on paper.

Practical rule: before you start, make sure you have capital to operate for at least 3 months without income. If you're already operating, always keep at least 2 months of fixed expenses in cash. When you negotiate large contracts with companies, try to get a 30-50% advance — it's not uncommon in the Colombian market and many companies accept it without problem if you propose it with confidence.

Error #7: Operating without written contracts with clients and suppliers

"We agreed on WhatsApp". "We have our word". "It's a trusted acquaintance". These phrases have cost millions of pesos to entrepreneurs who believed a verbal agreement was enough.

Colombia has a judicial system that can work, but it's slow and costly to activate. Without a written contract, proving that someone owes you money or breached an agreement is almost impossible. A WhatsApp can help, but it doesn't replace a document with clear conditions, deadlines, deliverables and consequences for breach.

You don't need a lawyer for every contract. For frequent services, create a basic template with: service description, value, payment method, delivery deadline, and intellectual property clause if applicable. There are free templates online. Sign it digitally (DocuSign, Adobe Sign, or even a hand-signed PDF scanned). If the contract exceeds COP 5 million, it's worth having a lawyer review it once — then use that version for all similar contracts.

The first year is the hardest — but avoidable

None of these errors is inevitable. All are predictable. The problem is that most entrepreneurs discover them after making them, not before.

If you're in the process of starting, the smartest investment you can make in the first few months is to pay for two or three hours of consulting with an accountant and the same with a lawyer specialized in commercial law. That's COP 300,000-600,000 that can save you years of headaches.

And if you've already made one of these mistakes — welcome to the club. The important thing is not the mistake but what you do with it. Most have a solution. Colombia has regularization mechanisms, periodic tax amnesties, and processes to formalize situations that started informally. Talk to someone who knows and act fast.

Frequently Asked Questions

❓ Do I need a SAS to start a business in Colombia or can I operate as a natural person?

It depends on your situation. As a natural person you can invoice and operate legally. A SAS makes sense if you have partners, want to limit your personal liability, or plan to grow and need financing. For solopreneurs with simple operations, natural person status is sufficient at the start.

❓ When am I required to register with the Chamber of Commerce?

If you have a commercial establishment (store, office or point of sale visible to the public), registration with the Chamber is mandatory. If you operate from home as a service provider, it's not strictly mandatory, but registration as an establishment facilitates banking procedures and dealings with corporate clients.

❓ What happens if I've been operating for months without electronic invoicing?

If you're already required to invoice electronically and haven't done so, the first step is to enable yourself with DIAN as soon as possible. There are penalties for not invoicing correctly (between 1-10 UVT per invoice), but the bigger risk is losing the deductibility of your income if DIAN audits you. There's no way to retroactively regularize invoices already issued informally, but you can minimize damage by starting today.

❓ Can I hire someone on a service provision basis to avoid paying social benefits?

Yes, but with conditions. A service provision contract is valid when the person works autonomously, sets their own schedule and has no subordination. If you hire someone who works exclusively for you, on a fixed schedule, following your instructions — that's a disguised employment relationship, and a labor inspector can declare the existence of an employment contract with all retroactive consequences.

❓ How much does it cost to formalize a business in Colombia?

Basic costs are: RUT with DIAN (free), registration with Chamber of Commerce as a natural person between COP 50,000-200,000 depending on declared assets, and if you incorporate a SAS, lawyer fees usually range around COP 500,000-1,500,000 plus Chamber fees. In total, starting formally can cost between COP 100,000 and COP 2,000,000 depending on the structure you choose.
