Best Accounting Software in Congo-Brazzaville: 2026 Comparison

In Congo-Brazzaville (Republic of the Congo), the headline 18% VAT rate isn't what your customers actually pay: a 5% surtax applies on top of most transactions, pushing the effective burden to roughly 18.9%. Software that only models the "standard" 18% VAT undercharges your customers and misstates your filings. It's exactly the kind of country-specific detail worth checking before picking a tool — especially since Congo-Brazzaville is sometimes confused with its neighbor, the Democratic Republic of Congo (DRC), which has a completely different currency, tax system and legal framework.

This guide compares the main accounting solutions for an SME based in Brazzaville or Pointe-Noire.

What accounting software must handle in Congo-Brazzaville

• 18% VAT + 5% surtax. The effective tax burden on most sales runs close to 18.9%, due to an additional surtax. A common point of confusion to get right in your invoices and filings.
• SYSCOHADA chart of accounts. The harmonized eight-class framework shared across the OHADA zone — Congo-Brazzaville is a founding member, unlike the DRC.
• CNSS at 24.28%. The overall social-security contribution rate, not to be confused with Cameroon's (~16.2% CNPS) or Gabon's (23% CNSS).
• Recent tax reform (ITS/TUS). The Impôt sur les Traitements et Salaires (ITS) and Taxe Unique sur les Salaires (TUS) regime has seen recent adjustments; honestly, some final parameters are still being confirmed as implementing texts are published — we'd rather tell you that than display a made-up figure.
• Notice period not uniformly fixed by law. Unlike some other OHADA countries with a statutory scale, Congo-Brazzaville leans heavily on collective bargaining agreements and the employment contract — your HR module needs to reflect that rather than impose a universal (and wrong) scale.
• Electronic invoicing from August 2026. A phased compliance rollout has been announced — worth planning for now.
• FCFA (XAF) currency, CEMAC zone. Like Cameroon and Gabon, but clearly distinct from the DRC, which uses the Congolese franc (CDF).
• Mobile Money: MTN Mobile Money and Airtel Money.

Comparing the solutions

Sage

Sage is used by several accounting firms in Brazzaville, but the 5% VAT surtax is rarely configured by default — verify it line-by-line on test invoices before any rollout.

QuickBooks

Without a SYSCOHADA chart or support for Congo's marked-up VAT, QuickBooks requires systematic manual rework — a real risk for local tax compliance.

Odoo Accounting

Flexible, but Congolese localization (VAT surtax, 24.28% CNSS) needs active verification with your integrator, since the ITS/TUS reform is still stabilizing.

NexaCore

NexaCore natively models Congo's 18% VAT plus the 5% surtax, and its 24.28% CNSS. Where ITS/TUS regulation is still evolving, we flag it clearly in the app rather than inventing a figure — and we update as soon as final texts are published. Congo-Brazzaville is treated as its own country, distinct from the DRC, with its own currency (XAF), its own payroll rules, and MTN Mobile Money/Airtel Money as native payment methods.

Which software should you choose?

• Choose Sage if your accounting firm requires it — be sure to verify the VAT surtax calculation.
• Choose Odoo if you have an integrator to validate the Congolese localization.
• Choose NexaCore if you want VAT and CNSS handled correctly from day one, with full transparency on regulatory points still in flux.

FAQ

Why is my VAT in Congo-Brazzaville above 18%?

Because a 5% surtax applies on top of the standard 18% rate on most transactions, pushing the effective burden to roughly 18.9%. Many non-localized tools miss this surtax entirely.

Is Congo-Brazzaville the same as the DRC?

No, not at all. Congo-Brazzaville (Republic of the Congo) uses the FCFA (XAF) and OHADA/SYSCOHADA law. The DRC (Democratic Republic of Congo) uses the Congolese franc (CDF) and doesn't apply the same legal framework. Confusing the two can throw off your entire books and payroll.

Is the notice period fixed by law?

Not uniformly. Unlike some other OHADA countries with a national statutory scale, Congo-Brazzaville relies heavily on collective bargaining agreements and the employment contract — always check the agreement that applies to your sector.

Does NexaCore show made-up rates for points that are still uncertain?

No. Where ITS/TUS regulation is still evolving, we flag it clearly rather than displaying an unconfirmed figure. See our accounting software in Congo-Brazzaville page for the current state of the data.
