Stella Source

Stella Source is the revenue engine for metals -- one platform for pricing, quoting, ordering, and payments -- built for the way metal is actually bought and sold. Most metal service centers and fabrication shops are leaving revenue on the table because their sales process is the bottleneck standing between them and revenue growth. Stella Source fixes that. Invite your customers to your online storefront where they can browse your catalog, see their specific pricing, and place stock or fabrication orders on their own time, without waiting on your team. Give your sales team the easiest path to an accurate quote no matter the sales channel, email, phone, fax, or online. Without ever leaving the inbox, your sales team can use AI-powered tools that turn any order request into a ready-to-send quote in minutes. And when the order closes, send digital payment links to convert to cash faster than ever. The result is a business that grows revenue from existing customers, reaches new digital-native buyers, and scales sales capacity. Your team spends less time managing the process and more time on the relationships that actually move the needle.

Synapto

Your software already moves your customers' money. Getting paid for it usually means a rebuild. Synapto is a UK payments provider built API-first for platforms, marketplaces and software companies that collect payments and pay people out. One integration covers both directions. Collect card and Direct Debit payments, then fire payouts from your own events: a job marked complete, an order dispatched, a shift signed off. Every payment in is matched to every payout out automatically, so reconciliation isn't a spreadsheet job. Payouts are configured, not built. No development project sitting on your roadmap waiting for a payments release. Pay-ins live in two days. Same-day and next-day payouts. GBP settlement on UK rails. Merchants switching from a standard PSP cut processing costs by 30% on average, and you get a named account manager who answers the phone, not a ticket queue.
