Migrate from TallyPrime to Microsoft Dynamics 365 Business Central

Each TallyPrime Company maps to a Dynamics 365 Legal Entity with its own GSTIN registration, fiscal year configuration, and base currency. We export the company name, GSTIN, mailing address, and fiscal year start date from Tally and create the corresponding legal entity in Dynamics 365 during the initial configuration phase. Multi-company Tally installations with inter-company vouchers map to separate legal entities with inter-company journal templates configured in Dynamics 365 to replace Tally's voucher-level inter-company references.

TallyPrime Ledgers map to Dynamics 365 General Ledger accounts. We preserve the complete ledger hierarchy (Group -> Ledger structure), GST classification (GST rate, HSN/SAC applicability), and opening balances as the G/L Account's opening transaction. Bank ledgers carry IFSC codes and account numbers into the Bank Account setup in Dynamics 365. Cost Categories and Profit Centers from Tally map to Financial Dimensions in Dynamics 365 Business Central or Cost Centers in Finance and SCM, allowing segment-wise P&L reporting equivalent to Tally's cost-category filtering.

Every TallyPrime voucher type (Sales, Purchase, Receipt, Payment, Contra, Journal, Debit Note, Credit Note) maps to a corresponding journal template or document type in Dynamics 365. We sequence voucher export by voucher date and apply a cutoff-date filter so that opening balances from the last closed period in TallyPrime land as the first open-period entries in Dynamics 365 without gaps or double-counting. Voucher numbering series, approval workflows, and print layouts are configuration-level items that do not migrate as code.

TallyPrime Stock Items with HSN/SAC codes, opening quantity, rate, value, and unit of measure map to Dynamics 365 Items. We preserve the stock item's opening quantity and value as the initial inventory posting, map the BOM (Bill of Materials) to the Dynamics 365 Bill of Materials structure, and carry forward the last purchase rate and standard cost as the initial item cost. Items with Track as Asset flag map to Fixed Assets in Dynamics 365.

TallyPrime Godowns map to Dynamics 365 Locations (Business Central) or Sites and Warehouses (Finance and SCM). Each godown's name, address, and GST location code carry forward as the warehouse's address and GST registration number. Stock-on-hand per godown from TallyPrime becomes the opening warehouse quantity in Dynamics 365. For single-warehouse migrations, we consolidate all godown stock under one warehouse and flag the consolidation for the customer's inventory manager to validate.

TallyPrime Party records with GSTIN, PAN, mailing address, contact details, credit limits, and opening receivables or payables map to Dynamics 365 Customer and Vendor records. GSTIN validation is preserved and the GSTIN number becomes the Tax Identification Number on the customer or vendor. Outstanding opening balances carry forward as open receivables (for customers) or open payables (for vendors) linked to the appropriate ledger accounts. Party types (sundry debtor, sundry creditor) map to the Customer or Vendor posting group in Dynamics 365.

TallyPrime UoMs are name/alias pairs that map directly to Dynamics 365 Units of Measure. Compound UoMs (e.g., 'dozen boxes') are split into their component units during export and reassembled in Dynamics 365 using the UoM conversion table. All UoMs are created before Item migration so that the Unit of Measure Group on the Item record can reference the correct conversion factors.

TallyPrime currency definitions and historical exchange rates map to Dynamics 365 Currency and Exchange Rate tables. We export the currency code, symbol, decimal places, and the exchange rate applicable at each voucher date, creating corresponding exchange rate records in Dynamics 365 so that multi-currency vouchers retain their original rupee-equivalent values.

TallyPrime allows highly customized voucher types with numbered series, print layouts, and approval configurations. We map standard voucher types (Sales Invoice, Purchase Invoice, Payment, Receipt, etc.) to their Dynamics 365 equivalents and flag any voucher type that uses a TDL-defined numbering series or print layout as a manual-rebuild item in the handoff documentation.

Fixed Assets tracked in TallyPrime via stock items with the 'Track as Asset' flag and separate depreciation books map to Dynamics 365 Fixed Assets. We export the asset register including book value, accumulated depreciation, and depreciation method, creating the corresponding Fixed Asset records in Dynamics 365 with the correct depreciation book and opening net book value as the initial acquisition cost.

GSTR-1, GSTR-3B, e-Invoice, and e-Way Bill JSON records from TallyPrime are exported as reference documents and stored alongside the corresponding voucher records in Dynamics 365. The GST portal maintains the authoritative filing history; we carry forward the last filed period reference number and ITC opening balance as explicit ledger opening balances in Dynamics 365. ITC carry-forward from TallyPrime's GST registers maps to the Input Tax Credit ledger in Dynamics 365.

TallyPrime Cost Categories and Profit Centers are exported as named dimension sets and mapped to Dynamics 365 Financial Dimensions. In Business Central, we create Department and Project dimensions; in Finance and SCM, we create the corresponding dimension types. Tally's segment-wise P&L reports map to Account Schedules in Dynamics 365 that filter by the migrated financial dimensions.
