One core, seven verticals, an accounting substrate underneath all of it.
What Wynk Systems actually does, stated per capability with its delivery status.
Each vertical is a full domain package — not a product code on a generic loan. Origination, servicing, arrears, restructure and write-off are modelled per vertical, and each one carries its own IFRS 9 staging and capital treatment.
| Vertical | What it models | Status | Evidence |
|---|---|---|---|
| Unsecured personal lending | NCA affordability, Reg 42–44 cost caps, Reg 23A capital | ✓ Live | Control |
| Mortgages | Secured amortisation, LTV bands, collateral revaluation | ✓ Live | Control |
| Debt consolidation | Settlement-quote orchestration across incumbent creditors | ✓ Live | Control |
| Vehicle and asset finance | Balloon structures, residuals, title-hold registry | ✓ Live | Control |
| SME term and revolving lending | Cash-flow scoring, covenant monitoring, director sureties | ✓ Live | Control |
| Invoice discounting and factoring | Debtor verification, concentration limits, recourse ledger | ✓ Live | Control |
| Trade finance | LC, guarantee and collection lifecycles on ISO 20022 and SWIFT MT | ✓ Live | Control |
Every rand movement writes its double-entry fact in the SAME database transaction that moves the money. There is no nightly accounting run to reconcile against, because there is nothing to reconcile: the ledger is not downstream of the product, it is inside it.
- Postings are hash-chained, so a rewritten history breaks the chain at the point of tampering.
- Any statement line walks back to its origin event, workflow step, identity and mandate.
- IFRS 9 staging IFRS 9 sorts exposures into three stages by credit deterioration; the stage decides whether the loss allowance is 12-month or lifetime. and Basel 3.1 capital consume the same facts as the financial statements.
- Six frameworks are projections of one fact set — a framework cannot disagree with another about what happened.

Multi-currency wallets and the value-added-services catalogue post to the same audited ledger as loan interest — one ledger, one chain, one truth.
Single and multi-currency wallets
Balances are integer minor units against a ledger account, so a wallet balance IS an accounting position rather than a number kept alongside one. Multi-currency wallets carry pockets, holds and an FX path that books the spread as it is earned.
Value-added services
Airtime, data, electricity tokens, municipal bills, subscriptions and insurance premiums. Margin is recognised as it is earned, on the same audited ledger as loan interest — there is no separate VAS book to reconcile.
Merchant acceptance
Interoperable QR and card acquiring with merchant settlement batches. The merchant payout arithmetic is a conservation identity: what was collected, less the disclosed discount, equals what is paid.
Every movement is idempotent
A replayed purchase returns the original outcome marked already-processed. A provider rejection auto-reverses and the customer is told it was refunded — the interface never renders a confirmation for money that came back.
Built to be inspected. A supervisor should be able to disprove our claims from the artefacts, not accept them from a slide.
- Row-level security per tenant, forced — the table owner cannot read across the boundary either.
- Two-eyes dual control on every money-adjacent and override action.
- POPIA minimisation, self-service DSAR, and no personal information in logs or URLs.
- goAML STR and CTR packs generated from ledger facts with a full submission lifecycle.
