Excel vs. ERP vs. Custom Software: Which to Choose to Scale Your Company in Colombia
A comparison of costs, risks and flexibility between Excel, a generic ERP and custom software, with a chart to decide based on your stage.
By Keyner Trillos· Updated
In short
- Excel works at the start, with fewer than 50 transactions a day and a small team.
- A generic ERP fits if your processes are traditional accounting and payroll; it becomes a brake when it charges per user and is costly to customize.
- Custom software makes sense when your operation is your competitive advantage and you need WhatsApp, payments and logistics integrated.
Almost every company starts in Excel. The problem comes when the file becomes the heart of the business: several people edit it, nobody knows who changed a price and a formula error throws inventory off. What's next: an ERP or your own software?
Comparison matrix
| Criteria | Excel / Sheets | Generic ERP (subscription) | Custom software |
|---|---|---|---|
| Initial cost | COP 0 | COP 5,000,000 – 30,000,000 in implementation | COP 8,000,000 – 35,000,000 in development |
| Recurring cost | Low | High: monthly fee per user | No per-user licenses, only infrastructure |
| Adaptability | High but fragile | Low: the company adapts to the system | Total |
| Security | Very low: no roles, risk of deletion | High | High, with roles and audit logs |
| WhatsApp and APIs | Almost impossible | Limited to connectors or paid modules | Native |
| Ownership | — | The vendor's | 100% the company's |
The dangers of running on Excel
- No real concurrency: several reps in the same file cause locks, overwrites and lost orders.
- No audit trail: you don't know who changed a price, deleted inventory or altered a discount.
- Data leaks: anyone with access can copy your entire customer base.
When a generic ERP becomes a brake
- Cluttered screens full of fields your team doesn't use, which slow down service.
- Per-user pricing: every new salesperson or assistant raises the monthly bill.
- Expensive, slow customization: a report or a connector can cost millions of pesos and take months.
Advantages of custom software
- Fast interfaces that work on phones, tablets and computers.
- Unlimited users with no per-person fees.
- Permissions by role and department.
- Integration with WhatsApp, payment gateways, DIAN invoicing and AI agents connected to your data.
What should you choose today?
- Excel: if you're validating the business and the operations team has fewer than 3 people.
- Standard accounting ERP: if you only need basic electronic invoicing and payroll, without complex operations.
- Custom software: if your sales, logistics or service processes set you apart and you want a long-term advantage.

Frequently asked questions
When should I move off Excel?
When several people edit it at once, you pass about 50 transactions a day, or an error in the file has already cost you money.
Custom software or ERP?
An ERP if your processes are standard (accounting, payroll). Custom software if the way you sell, produce or serve customers is your advantage and you need your own integrations.
