Boring engineering.
On purpose.
Most small-business SaaS gets built fast and held together with hope. GameStoreOS handles your store credit, your consignment payouts, your daily sales reconciliation — the parts where a wrong number costs you money or trust. We built it the way payment processors and accounting software get built, using patterns that have kept money straight for decades.
For the technically inclined (or the person they have look at this before signing): each section has a plain-English explanation and a short note on the engineering underneath.
A real ledger for everything financial.
Store credit and consignment balances aren’t a single number we keep updated — they’re the running sum of every entry. Issuing credit, redeeming it, splitting payment across cash and gift card, paying out a consignor: each is a recorded event you can replay a year from now. When a customer disputes a balance, the trail is complete.
Append-only ledger with classification snapshots at the moment of each redemption. Pending-redemption holds prevent over-spend mid-transaction. Reconcilers run on a schedule and a break-glass tool exists for the operator if something needs hand-correction.
All-or-nothing operations.
Multi-step financial actions — a consignor payout, a split redemption, a sale being ingested — run inside a single database transaction. Either every step writes or none of them do. You don’t end up paying a consignor twice because the system hiccupped after step two.
Service-layer enforces a transaction-per-operation rule. Audit log writes happen inside the same transaction as the business write — a recorded action and its audit row are always in agreement.
Reconciles with your POS, not against it.
Sales arrive from Wix as webhooks, with a polling backstop so nothing slips through if a webhook fails to deliver. We treat the POS as the canonical source of tender — what we say happened is what your POS recorded, not our best guess. If something gets out of sync, the operator has a one-click resync that reloads from source.
Idempotent ingestion keyed by Wix order and transaction IDs. Order Transactions API is the canonical tender source; offline-paid balances are projected from order activities. Operator-grade wipe-and-resync available for recovery.
Audit log on every state change.
Sign-ins, content edits, ledger writes, staff permission changes — recorded with who, what, and when. Searchable from inside the admin. The same trail that lets us help you investigate a discrepancy is the trail a compliance auditor would want to see if you ever needed one.
Centralized audit registry with enumerated action types. Emitted only on persistence events, not on draft mutations, so the log reflects what actually happened.
Two-stage releases. Infrastructure as code.
No update reaches your store directly. Every change runs on a separate dev environment first, against real data shape and the same code, and only ships to production when a human operator types the release command. No 3am surprise auto-deploys. The cloud setup itself — servers, permissions, secrets, queues — is described in code and version-controlled, not clicked together by hand.
Dev and prod are separate GCP projects with separate Supabase databases. Both environments are deployed from the same Terraform module, so dev is a real rehearsal for prod. Release is a single explicit step from a known-green dev commit.
Boring, dependable tools.
Postgres for the database. Next.js for the apps. Google Cloud and Supabase for the infrastructure. Firebase Auth for sessions. Nothing exotic, nothing that depends on a venture-funded startup staying alive, nothing chosen because it was trending. These are the same components run by companies who can’t afford to be down on a Saturday night either.
Row-level security in the database. TypeScript end-to-end. Capability-based authorization with compile-time exhaustiveness checks. Secrets stored in Google Secret Manager, never in source.
We keep an internal architecture brief covering the database schema, the deployment pipeline, the audit and authorization model, and the recovery tooling. Happy to share it with anyone doing a technical review before you sign on — just ask.
