Build a Prepaid Credit or Wallet System for Customers
If your customers buy credit in advance, spreadsheets and ad-hoc CRM fields create double-spend risk, disputed balances, and expiry chaos. A proper credit system with atomic updates, gateway top-ups, and clear rules protects cash, trust, and recurring prepaid revenue.
We build the digital wallet ledger that keeps every top-up and spend honest.
Sound Familiar?
These are the exact issues SaaS, education, marketplace, and loyalty teams face when prepaid credits are not a real ledger:
- Credit balances live in spreadsheets or ad-hoc CRM fields that two people can edit at once
- Customers dispute their available credit because top-ups and spends do not share one ledger
- Concurrent bookings or redemptions double-spend the same balance before either write completes
- Expiry rules are informal, so expired prepaid credits stay spendable or vanish without an audit trail
- Support and finance spend hours reconstructing who topped up, who spent, and what should remain
Industry research puts gift-card and prepaid breakage at 10–19% of value sold. Without tranche-level expiry and an audit trail, you cannot tell leakage from legitimate unused credit, and support arguments become he-said-she-said instead of ledger proof.
What the Credit System Actually Does
Top-up paid → wallet credited → spend authorised → balance syncs to CRM. No editable spreadsheet cell in the path.
Customer Tops Up
Pays via PayFast, Stripe, or Instant EFT for a prepaid credit pack
Wallet Credited Once
Idempotent ledger entry lands; retries cannot invent a second top-up
Spend Debits Atomically
Booking or order checks and reduces balance in one locked step
CRM & Expiry Stay True
Available credit, history, and tranche expiry stay visible and enforceable
Everything You Need for a Reliable Digital Wallet
Atomic Balance Ledger
Every top-up and spend is an immutable ledger entry. The available balance is derived and updated in the same transaction, so concurrent redemptions cannot invent phantom credit.
Gateway Top-Ups
Customers buy prepaid credits via PayFast, Stripe, Ozow, or your existing gateway. Successful payments credit the wallet once, with idempotent handling so retries never double-fund.
Spend & Redemption Controls
Bookings, orders, or usage draw against the wallet with a balance check and debit in one step. Insufficient credit is rejected cleanly instead of going negative in a spreadsheet.
Expiry & Tranche Rules
Credits expire on the rules you set. Debits consume the soonest-to-expire tranche first, so breakage and liability stay auditable for finance.
CRM Balance Visibility
Support and sales see available credit, recent top-ups, and spend history on the customer record, without opening a separate wallet spreadsheet.
Audit Trail & Alerts
Every movement has a reason code, timestamp, and reference. Failed top-ups, disputed balances, and near-zero wallets surface as alerts instead of silent leakage.
Platforms We've Wired into Prepaid Credit Systems
From Spreadsheet Credits to a Trusted Wallet
How an online education marketplace stopped R480K in annual credit leakage and cut balance disputes from 12 a month to under one.
The Manual Process
- Lesson packs sold via PayFast, then balances typed into a shared sheet and a CRM number field
- Two tutors booking the same learner at once could both debit the same remaining hours
- Expired packs stayed spendable because nobody ran a monthly clean-up
- Support spent 10–14 hours a week reconstructing top-ups from gateway exports
- Parents disputed balances weekly; goodwill refunds hid the real leakage
The Wallet Process
- Successful top-ups create one ledger credit with an idempotency key
- Bookings debit atomically; concurrent slots cannot both consume the same rand
- Expiry runs on tranches; soonest-to-expire credits spend first
- CRM shows available credit and history so support answers in under a minute
- Finance reconciles prepaid liability from the ledger, not from three exports

Frequently Asked Questions
How is a prepaid credit wallet different from an instalment plan or a deposit?
Instalment plans collect an outstanding balance over time. Deposits are accounting liabilities against future invoices. A prepaid credit or digital wallet is a customer-facing stored-value ledger: customers top up in advance, spend against an available balance, and may face expiry rules. The hard problem is balance integrity under concurrent spend, not scheduling collections or booking deferred revenue.
Which payment gateways can fund the wallet?
We regularly connect PayFast, Stripe, Ozow, Peach, and Netcash so a successful payment creates a single credit entry. Idempotency keys stop network retries from double-funding the same top-up. Card data stays with the gateway so your PCI scope stays on hosted pages or tokens, not raw card storage.
Can we keep balances visible in our CRM?
Yes. Available credit, last top-up, and recent spends sync to HubSpot, Pipedrive, Salesforce, or a custom CRM so support answers balance questions from the customer record. The CRM shows the balance; the wallet ledger remains the system of record.
How do you stop double-spend when two bookings hit the same wallet?
Spend checks and debits run as one atomic update with locking or versioning on the wallet. Two concurrent redemptions cannot both succeed against the same rand. Spreadsheet cells and CRM number fields cannot offer that guarantee.
How do expiry and unused credit work?
You define the policy: fixed dates, rolling windows, or no expiry. Debits consume the soonest-to-expire tranche first. Finance gets a clear view of liability and breakage instead of guessing which rows in a sheet still count.
How much does a prepaid credit wallet system cost?
A focused top-up and spend ledger with CRM visibility typically starts around R25,000. Full builds with multi-gateway funding, tranche expiry, alerts, and portal self-service usually land between R40,000 and R80,000. Most clients with material prepaid volume recover the cost within a few months by stopping leakage and support churn.
Stop Running Customer Credit on Spreadsheets
If prepaid balances can be edited by hand, you are one concurrent booking away from leakage, disputes, and lost trust.
