An ERP is the system of record. The obstacle to ecommerce is translation: marketplace data arrives in the marketplace’s vocabulary, while the ERP posts in yours. This guide covers the translation.
The ERP’s language versus the marketplace’s
| ERP vocabulary | Marketplace vocabulary |
|---|---|
| Ledger accounts, tax heads | Order, settlement and charge types |
| Invoice and voucher numbers | Order IDs, statement IDs, settlement IDs |
| GST structures per return | GST values embedded in reports |
| Warehouse master | Fulfilment centres |
Posting fails when the two are merged instead of translated.
What the ERP needs from ecommerce
Before anything reaches the ERP, it must be:
- Order-wise — each order as its own set of entries.
- GST-wise — tax per head and rate, not totals.
- Warehouse-wise — movement and COGS at the location level.
- Traceable — every entry points at the marketplace order.
- Reconciled — receivable, settlement and bank agree.
Preparing order-wise entries
Build per-order: revenue, marketplace charges, GST lines, TCS/TDS positions, settlement receivable, COGS and stock movement. Each maps to an ERP ledger. Verified against the settlement report, the set of entries is complete.
GST-wise and tax-ready posting
Entries carry the correct GST head and rate per line, so the ERP’s own GST structures accept them. Return data can be extracted from the ERP because the detail is already there at the right granularity.
Warehouse and inventory masters
Inventory and stock-transfer lines post against your ERP’s warehouse masters. COGS is recognised at the shipping warehouse; transfers move stock between locations without creating false revenue.
Working with Tally, SAP and Zoho
Each ERP receives the same accounting in its own structure:
| ERP | Posting shape |
|---|---|
| Tally | GST-ready ledgers, entry vouchers per order |
| SAP | Mapping to your chart of accounts and tax structures |
| Zoho | Postings to ledgers, tax profiles and warehouse masters |
The mapping differences are handled in the layer that posts, keeping source accounting identical.
Daily, not month-end
The effect of the layer is that the ERP is current continuously: every order accounted, every settlement reconciled, every stock movement posted. Month-end becomes a review of completed work — not a reconstruction of the month.
DeepEcom plays exactly this role: it does not replace your ERP; it makes your ERP ecommerce-ready.
