You sell on Shopify. Flowtopus handles your suppliers. One flow. Your call.

Shopify lets you create a purchase order and receive it. Flowtopus handles what happens in between: it emails the order to your supplier, reads replies and documents, flags changes to dates, quantities and prices, tells you when a supplier goes quiet, tracks deposits and landed cost, and warns you when a delay will cause a stockout.

Connect Shopify and Flowtopus imports your products, stock and sales: you don’t need a Stocky export for those. Stocky can’t export suppliers: you name your first supplier during setup, then add the others and assign them from each product’s page. Stocky purchase orders aren’t imported: you keep read-only access to export your completed purchase orders as CSV files from Stocky’s built-in reports for at least 90 days after August 31, 2026, and your next orders start in Flowtopus.

You install the public Shopify app and authorize the inventory, product, and order access Flowtopus needs. Your Shopify store is then linked to your Flowtopus organization.

Free includes one Shopify store, up to 100 master SKUs and one supplier, with stock visibility, low-stock alerts and reorder points. Starter adds purchase orders and sending, with 50 purchase orders, 20 supplier documents, 40 supplier emails and 100 automatic reorder suggestions a month; Pro and Scale raise the limits and make automatic suggestions unlimited.

Each file a supplier attaches to an email, each PDF or photo you forward from WhatsApp once it is linked to an order, and each file you upload counts as one document. Small images such as signature logos don't count. Flowtopus reads the first 4 files of each email or WhatsApp forward, and every file counts: ask suppliers to spread larger sets across several emails. Each supplier message Flowtopus reads counts as one email, with or without files; messages you send don't count. Each product Flowtopus proposes to reorder counts as one suggestion. Each purchase order created, including the drafts Flowtopus prepares, counts toward the monthly purchase orders: 50 on Starter, 500 on Pro and 2,500 on Scale. Allowances renew on the 1st of each month (UTC). When an email brings more files than you have documents left, its files aren't read; once your email allowance runs out, new supplier messages aren't read either. After the renewal or an upgrade, upload the files from the original email, which you can download in Flowtopus, or ask the supplier to send them again. Supplier replies still reach their order, and low-stock alerts keep running.

No. Critical inventory calculations remain explainable, and an authorized human must review consequential purchasing decisions before a PO is sent.

Flowtopus connects supplier emails and documents to the correct PO, extracts commitments and exceptions, and shows their likely operational impact. Starter includes 20 documents and 40 supplier emails a month; Pro and Scale raise the limits.

Yes, from Starter. Each team member connects their phone in Settings, forwards the supplier's WhatsApp messages to the Flowtopus number and, within two minutes, sends the order number on its own, for example PO-1051. Without it, Flowtopus looks for an order number in the messages, or holds them until you choose the order. Flowtopus reads the forwarded text, PDFs and photos and proposes the changes for you to review, as with a supplier email. You can also write what a supplier told you by phone or on WeChat: it is marked as your team's note. Excel files sent on WhatsApp are not read: have .xlsx or CSV proformas sent by email, or upload them in Flowtopus. Flowtopus never sends WhatsApp messages: to send an approved order on WhatsApp, you send it yourself and record it in Flowtopus.

No. With the Flowtopus service, your orders leave from the Flowtopus sender and your suppliers reply to your Flowtopus reply address: no mailbox connection at all. You can also send from your Google or Microsoft address without granting reading access, forward the exchanges you choose, or send the prepared messages yourself. Full synchronization remains a separate, optional connection.
