Services
Each of these is usually its own product at its own vendor, held together by imports, exports and a spreadsheet someone updates by hand. StreamBit designs and builds all four as one system, animated by the same event log.
01
A register app for the lane
A real register interface designed for the way clerks and customers actually move through a sale — not a checkout screen bolted onto inventory software. Cash, card, split tender, refunds, voids and the audit trail are first-class, not afterthoughts.
Deliverable — Lane register (iPad)
offline-mode checkout · multi-till audit trail · cash drawer / scanner drivers
02
Counts that reconcile to the event log
Cycle counts, receiving scans, dock arrivals, transfers between locations and stock adjustments. Every change is recorded as an event, so the on-hand quantity at any point in time is derivable from the log — not overwritten when a count gets rerun.
Deliverable — Receiving + cycle-count app
barcode-driven scans · event-log on-hand derivation · location transfers
03
One source of truth for listings
The same product data that drives the register drives the public storefront, so prices, stock and descriptions stop drifting behind the till. Catalogue edits flow through the event log and reach the site without a separate, fragile sync job.
Deliverable — Storefront + catalogue editor
event-driven listings · stock pulled from the projection · zero nightly sync
04
Books that read off the same ledger
Daily close, payouts, tax summaries and owner reports are projections of the same event log the till writes to — so close at the end of the day reconciles by construction, not by a manual spreadsheet at midnight.
Deliverable — Daily-close dashboard
till-driven payout report · tax summaries · owner KPI views off the same log
How they fit together
The four pillars above are not four products bolted together. They are four different views of the same event log — the same source of truth a sale at the till writes to.
The point-of-sale is a write path into that log. Inventory is a stock-state projection. The web catalogue is a listing-state projection. Back-office is a money-state projection. They cannot drift, because there is no separate source to drift from.
An event-sourced backbone reads like your business actually runs. Any past day, any past sale, any past inventory snapshot can be replayed on demand to answer a question your old CSV export could not.
That is what holds the four pillars together — not glue, not a nightly job, not a spreadsheet someone updates by hand.
