There is a reason so many ecommerce companies run their marketplace finance in spreadsheets next to their ERP. The ERP is very good at postings and bad at marketplace feeds, and the layer that should translate between the two usually does not exist.
What an ERP is actually good at
An ERP — Tally, SAP, Zoho — is a system of record. It holds chart of accounts, GST ledgers, warehouse masters, and posting rules. It is built to reliably record an accountant’s entries.
What it is not built for is the messy, delayed, cross-referenced data that comes out of marketplaces:
- Settlement reports keyed to statement IDs, not invoice numbers.
- Refunds weeks after the original sale.
- Charge types in the marketplace’s vocabulary.
- TCS and TDS embedded in payouts.
The mismatch, made concrete
| Your ERP expects | Marketplaces provide |
|---|---|
| A clean sales invoice | An order feed with a settlement later |
| Net revenue | Gross sale minus charges you must decompose |
| Cash on receipt | Payouts pooled across many orders |
| One tax line | GST per charge, TCS and TDS on top |
| Leading inventory | Warehouse stock movements |
| Gradual reconciliation | A monthly settlement mystery |
Pumping the second column unchanged into the first produces books that nobody can reconcile.
The accounting layer
The accounting layer sits between the marketplaces and the ERP. It does four jobs in sequence:
Connect. Aggregate order, settlement, payout, inventory and return data from every marketplace into one structured store.
Understand. Turn raw events into order-wise facts: what was sold, what was charged, what tax applies, what inventory moved.
Reconcile. Match expected, settled and received money until receivables, settlements and bank agree.
Account. Build detailed accounting entries — order-wise, GST-wise, warehouse-wise — and post them into the ERP in the ERP’s own structure.
Why the ERP does not do this itself
Automating it inside the ERP would mean teaching the ERP marketplace semantics: multiple settlement formats, evolving charge types, TCS variants, warehouse-led fulfilment. That work changes monthly and belongs to a layer whose entire job is eating structured ecommerce data.
The ERP stays the canonical ledger. The accounting layer makes the ERP ecommerce-ready.
What changes when the layer exists
- The books are per order, not monthly summaries.
- GST-wise and warehouse-wise detail exists behind the totals.
- Marketplaces, bank, and ERP reconcile to the same numbers.
- Month-end stops being a chase and becomes a review.
DeepEcom as that layer
DeepEcom does not replace the ERP. DeepEcom makes the ERP ecommerce-ready — connecting marketplaces, understanding every order, reconciling every payout, and posting detailed accounting into Tally, SAP and Zoho.
