Step 1 — Requirement study
We map the document flow: enquiry to order, order to delivery, delivery to invoice, invoice to collection, and for manufacturers, material issue to production to dispatch. That produces the voucher types, approval points and user roles the configuration needs, and usually reveals two or three manual registers that can be retired immediately.
Step 2 — Masters design
The chart of accounts is built so the P&L and balance sheet read the way your management and your CA want, not as a flat list. Item masters get consistent naming, groups, units, HSN codes and tax categories, with aliases and barcodes where billing speed matters. Party masters carry GSTIN, credit limits, credit days and transport defaults.
For distributors with large item lists, de-duplication happens here. It is tedious and it is the highest-value hour of the whole project.
Step 3 — Migration and opening balances
We migrate masters and opening balances rather than importing years of messy transactions. Ledger balances, party outstandings bill-by-bill, stock quantity and valuation, and pending orders are entered and then matched against your existing system. Nothing is signed off until the trial balance agrees to the rupee and stock valuation agrees to the item.
Step 4 — GST, formats and controls
GST configuration is tested with real documents: an e-invoice with an actual IRN, an e-way bill with an actual number, a credit note, an RCM purchase and an export invoice where applicable. Invoice, challan and packing-slip formats are designed and printed on your own printers. User rights, back-dated entry restrictions and the audit trail are switched on before go-live, not after an incident.
Step 5 — Training, parallel run and go-live
Staff are trained by role, then you run one billing cycle in parallel. Parallel running feels like duplicate work and it is the cheapest insurance available — it catches rate errors, tax mapping mistakes and stock issues while the old system is still there to compare against. Go-live happens at a period boundary, ideally the 1st of a month.
Step 6 — First GST cycle and handover
We stay through the first GSTR-1 and 3B produced from Busy: HSN summary checked, 2A/2B reconciled, e-invoice register matched to the sales register. Once that filing is clean, we hand over with documentation of your configuration and move you onto AMC for ongoing support.
