Building a financial dashboard with Stripe, Shopify, and Plaid without writing a reconciliation engine

Your data lives in three places If you run a business that sells through Shopify and processes payments with Stripe, your financial data is split across three systems. Stripe knows your payment volume and fees. Shopify knows your orders, refunds, and its own payouts. Your bank knows what actually landed in your account and what you spent. Building a dashboard that combines all three means writing OAuth flows, managing API keys, syncing data on a schedule, normalizing amounts (Stripe uses cents, Plaid uses dollars with negative signs for deposits), and building matching logic to figure out which bank deposit corresponds to which payout. That is months of work before you display a single number. FlowCheck handles all of that. You connect your accounts, and every endpoint returns unified data. Here is how to set it up from scratch.
