Definition of corporate identity and legal parameters
The first and most critical stage in the installation of a corporate ERP system is to create the company card of the legal entity completely and in full compliance with the legislation. Legal fields such as the official company title, Tax Identification Number (TIN), Tax Office, Trade Registry Number, MERSIS Number and NACE code declared in the Trade Registry Gazette must be entered into the system correctly, verbatim.
Especially in Revenue Administration e-Document systems such as e-Invoice, e-Archive, e-Delivery Note and e-Ledger; Even a single character typo in the title or tax number causes schema validation errors in e-document submissions and certificate approvals. For this reason, after the company opening card is created, cross-checking should be done with the Revenue Administration e-Document portal and Interactive Tax Office records.
Company and branch configuration checklist
The following control table summarizes the basic parameters and rules to be considered for error-free opening of the company card and subunits in ERP installation:
| Definition Parameter | Description and Scope | Critical Warning | Relevant ERP Module |
|---|---|---|---|
| Legal Title & TIN | Official full company title in the tax office and registry record | Checked one-to-one in e-Document and official book certificates | General Accounting & e-Transformation |
| MERSİS & Registry No | Turkish Commercial Code mandatory legal entity registry information | Mandatory in e-Invoice footnote and e-commerce sites | Finance & Document Designs |
| Branch & Workplace Code | Distinction of physical store, factory, warehouse or regional directorate | Determines branch-based balance sheet, income statement and VAT distinction | Accounting, Sales & Stock |
| Default Currency | The main currency in which the company keeps its legal books (TRY etc.) | Cannot be changed after going live; requires cross exchange rate | General Ledger & Cash/Bank |
| Financial Working Period | Calendar year (01.01-31.12) or special accounting period dates | Past dated voucher entries are blocked with period locking | End of Period & Transfer Transactions |
Multi-branch and multi-warehouse organizational architecture
Growing businesses have factories, regional directorates, retail stores and contract manufacturing workshops, in addition to the head office. Each location should be opened with an independent branch code on ERP; Each branch's own virtual and physical warehouses, cash and POS accounts should be associated.
In inter-branch goods transfers, the 'Warehouse Transfer Receipt' is used to ensure that the shipment is monitored bilaterally as stock in transit and stock receiving delivery. Likewise, in inter-branch money transfers, automatic transfer and current account settlements and chart of accounts integration are kept consistent.
Fiscal period management, transfer and change discipline
A separate working period is opened on the ERP for each fiscal year. After the closing offsets are made at the end of the year, the transfer wizard is run and the stock inventory, current account balances, cash/bank holdings and check-note portfolio are transferred to the new period as an opening slip.
After going live, arbitrarily changing parameters such as company name, chart of accounts main breakdowns or stock valuation method (FIFO, Weighted Average, etc.) disrupts the balance of all financial reports. For this reason, the company definitions screen should be authorized only to system administrators (Admin) and every intervention made should be monitored through the audit log.
