Custom accounting software, audit-ready by default.
We've shipped a double-entry accounting system with multi-currency, bank reconciliation, GST returns, fixed-asset depreciation, subscriptions, period close. If your business is large enough that QuickBooks / Tally / Zoho start hurting, here's what the custom build actually involves.
A production-grade accounts module already built and running. We ship a custom one for clients who need their own.
ragenaizer.com / accountsWhat goes inside a real accounts.
These are the moving parts we've shipped before. Your custom build picks a subset — and we tell you upfront which parts are worth re-implementing and which ones aren't.
Double-entry ledger
Journal-first design — every transaction is balanced by construction. Reports derive from journals, never the other way around.
Multi-currency
Transactions in any currency. FX rates at transaction time, FX revaluation at period close. Realised + unrealised gain/loss handled cleanly.
Bank reconciliation
Statement import, auto-match, fuzzy match for slight differences, manual override with audit trail.
AR + AP
Invoices, recurring invoices, credit notes, vendor bills, purchase orders, AR / AP aging.
Tax engine
GST + TDS for India out of the box. Returns generation (GSTR-1, GSTR-3B). Extensible for other jurisdictions.
Fixed assets
Depreciation methods (straight-line / WDV / units-of-production), batch run, disposal, gain/loss postings.
Subscriptions / recurring billing
Plans, trials, metered usage, dunning. Webhooks from Stripe / Razorpay auto-post.
Period close & audit lock
Soft close, hard close, year-end close with check-lists. Reopen-with-reason if you must.
The problems that don't show up in the demo.
These are the ones that take a custom build from "works in a screenshot" to "works in production for three years." We've already learned them once.
- 01 Audit trail that survives schema migrations — five years from now, the journal entry needs to be readable.
- 02 Period locking that allows late adjustments via reversal-and-correction without rewriting history.
- 03 Multi-entity / multi-book consolidation with intercompany eliminations.
- 04 FX revaluation that posts correctly to realised / unrealised buckets at the right granularity.
- 05 Number-sequence allocation in a multi-writer cluster without gaps — accountants notice.
How we'd put it together.
ASP.NET Core, Postgres (the relational integrity matters here — no NoSQL), a separate read-model service for reports, and a Hangfire / Quartz worker for end-of-period batch jobs. Audit log lives in an append-only event store.
We'll tell you when not to build.
Custom isn't always the right call. We've shipped Ragenaizer so we can say that honestly.
- →The accounts is the moat — your competitor can't have the same one.
- →You have compliance / sovereignty / data-residency requirements no SaaS will satisfy.
- →You need to integrate at a level deeper than off-the-shelf vendors expose.
- →Per-seat pricing across thousands of users makes the build cheaper inside 24 months.
- →The workflow is generic enough that a configurable platform will do.
- →You want it in weeks, not quarters.
- →You'd rather buy than own — let someone else maintain the accounts forever.
- →Your engineering capacity should go to the parts of your product that no SaaS covers.
