What is each one (without cartoons)
- Alegra — Cloud, light and loved by accountants and micro-SMEs: local electronic invoicing (Colombia, Mexico, Peru and more), expenses, basic inventory and accounting reports. Affordable prices per plan according to invoices and users.
- Siigo — The Colombian accounting giant (bought Aspel in Mexico): robust formal accounting, electronic payroll, strong link with the accounting union. Deeper and heavier than Alegra.
- Aura — Complete operation platform: CRM, WhatsApp inbox with AI agents, POS, online store, multi-channel inventory, billing (CFDI in Mexico), payroll and finances — all in a single system for $599 USD/month per organization.
The structural difference: accounting-centric vs operation-centric
Alegra and Siigo were born from the receipt: their center of gravity is to record well what ALREADY happened (the invoice, the expense, the entry) to comply with the tax authority and give order to the accountant. Everything else — sales, customers, channels — orbits around the record.
Aura is born from the other side: from the moment the sale HAPPENS. The lead that writes on WhatsApp, the AI that attends to it, the order, the payment, the inventory that goes down — and in the end, yes, the invoice and the entry as an automatic consequence. Accounting is the mirror of the business, not the business.
Neither approach is "better" in the abstract: it depends on what problem you're hurting about. If your pain is fiscal/accounting, the first. If your pain is operating and selling with 6 disconnected tools, the second.
Face to face on what matters
- Local electronic billing: all three comply in their countries (DIAN in Colombia, SAT in Mexico). Siigo and Alegra with more years of drag in Colombia; Aura with complete CFDI 4.0 in Mexico, including the global POS.
- Formal accounting for the accountant: Siigo wins in pure accounting depth; Joy in simplicity. Aura generates the information from the operation and exports it — and for the accounting office there is the accountants module.
- Sales and customers: Aura without competition in this trio — CRM, WhatsApp with AI, POS and ecommerce do not exist in Alegra/Siigo or are basic modules.
- Inventory: basic in Alegra, functional in Siigo, multi-channel and with recipes in Aura (counter + online + marketplaces of the same stock).
- Price: Alegra the cheapest to invoice; I'm intermediate with serious accounting; Aura higher monthly payment but replaces the entire stack (CRM + POS + store + WhatsApp + billing + payroll).
Verdict according to your case
- You are an accountant or micro-business that ONLY invoices and records expenses: Alegra — unbeatable price and simplicity.
- Colombian company with demanding formal accounting and accountant who lives in Siigo: Siigo.
- Business that sells (store, restaurant, services, ecommerce) and wants to stop sewing tools: Aura — and the 14-day trial for $14 USD lets you test it with your real operation.
- Common hybrid path: operate in Aura and provide the accountant with the reports and receipts — each their own tool.

Do Alegra and Siigo work in Mexico?
Yes: Alegra has a Mexico version with CFDI, and Siigo operates in Mexico through Aspel (which it acquired). Local depth varies by product — check stamping, accessories and payroll depending on what you need.
Does Aura replace my accountant?
No, and none of the three. Aura generates and organizes information (invoices, sales, expenses, payroll) so that your accountant can close and declare in a fraction of the time. The accountant provides fiscal criteria; The system eliminates waste.
Can I migrate from Alegra or Siigo to Aura?
Yes: customers, products and balances are imported via CSV/Excel, and your historical CFDI lives in the SAT anyway. The typical thing is to start the operation in Aura and retain consultation access to the previous system for a few months.
Which one has better handling of WhatsApp?
Aura, by design: WhatsApp Business API multi-agent inbox with AI agents that serve, quote and collect. In Alegra and Siigo, WhatsApp is not part of the product — they are accounting systems, not conversational sales.
