Three accounting tools became one

The problem

Coastal Supply Co. is a regional distributor of restaurant supplies — paper goods, kitchen tools, smallwares, cleaning chemicals. They run about 2,400 SKUs out of one warehouse with nine employees. Margins are tight; the business survives on volume and operational discipline.

The operational discipline was held together by three separate tools. QuickBooks Enterprise handled accounting. A separate warehouse management system handled inventory. ADP handled payroll. The three systems cost roughly $1,800 a month combined and never agreed with each other. Inventory adjustments in one system didn't match cost-of-goods entries in another. Reconciling them at month-end took the owner two full days.

Worse: nobody could answer simple questions in real time. Which SKUs were actually profitable? Which were tying up cash in slow stock? When should the next reorder of the top movers run? The data existed somewhere across the three systems. Nobody had time to combine it.

The setup

Coastal Supply migrated all three tools to TwinBooks. Inventory data, accounting data, and payroll data ended up in one system with one login and one source of truth. The migration took three weeks — the bulk of the work was matching SKUs to ledger accounts cleanly so the AI insights would be accurate.

TwinBooks' AI layer ran over the unified operational data. The first run flagged forty-two SKUs as unprofitable at current pricing, identified about $34,000 stuck in slow-moving stock, and suggested reorder timing on the top fifteen movers based on actual sales velocity instead of gut feel.

How it works

An inventory transaction — a sale, a return, a transfer — feeds the accounting ledger automatically. There's no separate journal entry to make. Payroll runs from the same employee and hours data already in the system. End-of-month closes in half a day instead of two days.

The AI insights run continuously, not monthly. The owner sees SKU profitability change in real time as costs and pricing shift. When a top mover is approaching the reorder threshold, TwinBooks surfaces it before stockout becomes a customer problem. When cash is locked in slow stock, the platform suggests promotions, bundle pricing, or vendor returns to free it up.

The owner runs reports from one dashboard instead of stitching three exports together in Excel.

What changed

Tooling cost dropped significantly — replacing three SaaS subscriptions with one. End-of-month time dropped from two days to half a day. SKU profitability decisions shifted from monthly hindsight to real-time insight. Cash freed up from slow stock got redirected into top movers.

The owner's role changed. Before TwinBooks, end-of-month was bookkeeping triage. After, end-of-month was strategy — looking at which products to push, which to drop, where to invest the cash that came back.

Why this matters for inventory businesses

Distributors and warehouses live and die on margin. The difference between a business that grows and one that struggles is usually visibility — knowing which SKUs make money, which to reorder when, and where cash is locked. That visibility is hard to get when inventory, accounting, and payroll live in three different tools.

TwinBooks consolidates the operational stack into one platform and runs AI over the unified data. Distributors stop paying for three subscriptions. They stop reconciling tools that don't match. They start making decisions in real time instead of monthly.
