Chart of accounts, Sage 100 export, WAEMU VAT, and audit trail: everything your finance leadership needs to digitize procurement while staying compliant.
Procura team · April 2026 · 10 min readThe OHADA Accounting System (SYSCOHADA) is the unified accounting framework adopted by the 17 member states of the Organization for the Harmonization of Business Law in Africa. Created in 2000 and substantially revised in 2017, it is the mandatory legal framework for the bookkeeping of every company operating in the OHADA zone, from Benin to Chad and including Senegal, Côte d'Ivoire and Cameroon.
The revised SYSCOHADA borrows heavily from IFRS while reflecting African economic realities. Notably, it introduces the cash flow statement, comprehensive income and specific rules for financial instruments. For procurement, it requires complete traceability from PO through payment, with supporting documents for every entry.
In a procurement context, SYSCOHADA compliance means every disbursement must be backed by a purchase order, a goods receipt and a validated invoice. Missing documents expose the company to tax reassessments and qualified opinions from external auditors. Digitizing procurement with a tool like Procura makes compliance natural by automatically archiving the full sourcing file.
Companies that ignore SYSCOHADA compliance face penalties ranging from fines to criminal liability for executives. In the WAEMU zone, tax controls are progressively digitizing, making accounting inconsistencies easier for the authorities to detect.
The SYSCOHADA chart of accounts organizes procurement around three core account families. Account 401 'Suppliers' captures liabilities to vendors. On every validated invoice, account 401 is credited with the gross amount, reflecting the company's commitment to pay within agreed terms.
Class 60 accounts capture expenses by nature. Account 601 covers merchandise purchases, 602 raw materials, and 604 external services. Account 607 'Merchandise purchases' is heavily used in trading companies. Every entry must be split by purchase nature to enable detailed cost-structure analysis.
Account 445 'State, recoverable VAT' is central for managing VAT on purchases. The standard WAEMU rate is 18%, but some goods qualify for exemptions or reduced rates. Account 4451 covers VAT on fixed assets, while 4452 covers VAT on goods and services. Correct VAT bookkeeping is critical to exercise the right to deduct.
Procura automatically generates SYSCOHADA-compliant journal entries from every validated invoice. The system splits the net amount to the right expense account, the VAT to the matching 445 account, and the gross amount to the vendor's 401. This automation eliminates coding errors and accelerates month-end close.
Sage 100 Comptabilité is the most widely used accounting software in Francophone Africa. Integrating a digital procurement tool with Sage 100 is therefore mission-critical for finance teams. Procura exports journal entries in native Sage 100 format, ready to import without manual rekeying.
The PU (purchases) journal receives vendor invoice entries. Each line carries the account number, normalized memo (invoice number + vendor name), debit or credit amount, document date, journal code and supporting-document reference. Procura honors Sage's max field lengths and encodes special characters correctly.
The BK (bank) journal records disbursements when invoices are actually paid. When a payment is issued from Procura, the system generates the settlement entry: debit vendor account 401, credit bank account 521. Partial payments and credit notes are handled automatically with the matching reconciliation entries.
The export file is a CSV with semicolon delimiter, Windows-1252 encoding and a column structure that matches Sage 100 import specs. Companies using other accounting tools (Saari, Ciel, Tom2Pro) can configure a custom mapping in Procura to align the export format with their tool.
The West African Economic and Monetary Union (WAEMU) has harmonized VAT across its 8 member states with a standard rate of 18%. That rate applies to the majority of goods and services purchased by companies. There are still country and category variations though: Senegal applies a reduced 10% rate on some food items, while Côte d'Ivoire exempts certain agricultural inputs.
Managing VAT in the CEMAC zone has additional wrinkles. Cameroon applies 19.25% (VAT + additional centimes), Gabon 18%, and the Republic of Congo 18.9%. Companies operating across multiple countries must handle these variations in their bookkeeping and tax filings, which significantly complicates manual invoice processing.
The deductible-VAT mechanism requires every purchase invoice to meet strict formal conditions: mention of the vendor's tax ID (NIF), separate net amount and VAT, invoice date and number. A non-compliant invoice doesn't allow VAT to be deducted, which represents an 18% additional cost for the company. Procura automatically checks formal compliance on every invoice during OCR extraction.
VAT returns are filed monthly in most OHADA-zone countries. Procura generates a deductible VAT recap by period, split by rate and country, simplifying return preparation. Reconciling filed VAT against booked VAT becomes automatic, reducing tax-reassessment risk.
The audit trail is the documentary chain that lets you reconstruct the path of a transaction from origin to accounting entry. SYSCOHADA explicitly requires every journal entry to be backed by reliable, dated supporting evidence retained for at least 10 years.
In a manual procurement process, the audit trail is often incomplete: paper POs go missing, approval emails get deleted, invoices are filed without a PO reference. During an external audit or tax control, the inability to produce these documents triggers qualified opinions from the auditor or expense disallowance from the tax authority.
Procura automatically builds a complete, timestamped audit trail for every procurement transaction. Every step is tracked: requisition creation, manager approval, PO issuance, goods receipt, invoice validation, payment authorization. Everything is bundled into a single sourcing file, viewable in one click and exportable as PDF for auditors.
Compliance is not just archiving. It also means segregation of duties (the requester doesn't validate the invoice), respecting approval thresholds, and tracing modifications. Procura implements these controls natively: configurable approval workflows, change log with user identifier, and locked records that can't be deleted once validated.
