Store Profit

StoreProfit shows Shopify merchants what they actually keep. Shopify reports revenue. StoreProfit subtracts COGS, landed costs, shipping, payment and platform fees, discounts, returns and ad spend to show net profit per order and per product, with the full cost breakdown behind every number. Ad spend syncs automatically, so the P&L stays current without a spreadsheet. It also covers the two things profit dashboards usually leave out. Cashflow: a forecast of your cash position, your runway, and upcoming bills and payouts. Inventory: demand forecasting, reorder alerts, sell-through and dead stock by SKU, and purchase order planning based on sales velocity. Most tools do profit, cash or inventory. StoreProfit does all three in one app, so you can see whether a product is profitable, whether you can afford to reorder it, and when to place the order.

Synup

Synup is a local marketing platform for agencies, resellers, and multi-location businesses. You run it by talking to it. Sydekick, Synup's AI agent, executes local marketing work through conversation: no dashboards to click through, no data to collect by hand, no reports to stitch together. Meet Sydekick:- Tell Sydekick to update business hours across 400 locations, respond to this week's reviews in each client's brand voice, or pull a performance report across the full portfolio, and it does the work. Sydekick goes well beyond routine execution. It audits your local presence and flags what needs fixing. It browses websites to fetch the information it needs. It builds custom landing pages. It designs reports to answer the exact question you asked, in the format you want, rather than forcing you into a fixed reporting template. Skills and Playbooks:- Sydekick works from skills and playbooks. Start with the ready-made library covering common local marketing workflows. Create your own skills for the processes unique to your agency or brand, and reuse and refine them over time so Sydekick gets better at your specific work. When you're stuck, just ask the Synup team. Listings Management:- Business information stays in sync across Google, Apple, Bing, Facebook, and every major listing platform. Bulk changes across thousands of locations happen through a single instruction. Synup verifies that data is indexed and visible to searchers, not just submitted. Reputation Management:- Sydekick monitors reviews across Google, Facebook, and every major review site, drafts and posts responses that match each brand's voice, and runs review request campaigns over email and SMS to grow review velocity for every location. Social Media Management:- Publish across Google Business Profile, Facebook, Instagram, and LinkedIn for hundreds of locations. Sydekick generates localized content per location so every post feels native to its market. Local SEO Analytics:- Local rankings, GBP performance, and review sentiment tracked for every location. Ask Sydekick for the analysis you need in plain language and get answers across the portfolio, or have it build a custom-designed report for a client presentation. Local SEO Tools API:- Agencies, platforms, and SaaS companies use the Synup API to power listings sync, review management, and GBP automation inside their own products. Headless and built to scale across millions of locations. Synup MCP Server:- Synup connects to Claude, ChatGPT, and any MCP-compatible AI assistant, so teams can query listings, pull review data, and manage locations through the AI tools they already use. White-Label Everything:- Every surface can be fully white-labeled under your brand: custom domains, your logo, your colors, your client-facing experience. Your clients never know Synup is in the stack. Synup keeps every location accurate, responsive, and visible in search. You describe the outcome. Sydekick does the work.
