About Seam

Seam is self-hosted B2B operations platform for a company and its contractors

Seam is a finished, self-hosted B2B platform for two companies that work together: one hands out the work, the other does it, and both look at the same record instead of two spreadsheets and a WhatsApp thread. Each order carries its own status pipeline, the terms both sides accepted, the documents and e-signatures, the invoice and its payment. Every change is dated and attributed, so "when did we agree that" has an answer. Built for small and mid-sized firms in construction, logistics, e-commerce fulfilment, vehicle import, agriculture and general subcontracting. Ships with 28 opt-in trade packs, per-country VAT, tax and filing data for 15 countries, and a complete interface in 13 languages. Python and vanilla JavaScript. Flask and waitress are the only two dependencies. No database server, no front-end build, no third-party services required. 2,204 automated checks pass against a real server. When one company subcontracts to another, the job lives in two places. The buyer has it in their spreadsheet, the contractor has it in theirs, and the agreement itself is somewhere in a mail thread. Nobody can say what was agreed, when the status changed, or who approved the extra work, so every dispute becomes an argument about whose version is right. Following the Github link you can see everything related to the platform in detail, also you can give it a test with demo account! Sold as-is: a complete codebase with no users and no revenue. Priced accordingly. This project has exceptional capacity and real potential, for a well developed useful tool with great working capacity and opportunity for global development with the right approach, marketing and monetization.

Next step: Pick one trade and go narrow. The platform ships with 28 opt-in add-on packs, each adding the fields, terms and stages one industry actually uses: construction subcontracting, e-commerce fulfilment, vehicle import, freight, agency work and more. A buyer does not have to be a horizontal tool competing with everything. They can launch as "the system for electrical subcontractors" or "the system for vehicle importers", sell into one trade association, and switch on the next pack when the first market is won. No development is needed to change vertical.Or go wide geographically. The interface is complete in 13 languages, and company registers, VAT rules and national identity schemes are implemented for 15 countries. Most competitors in this space are single-market and English-only. A buyer can open in Poland, Romania, Greece or Turkey on day one, in markets where the incumbent is a spreadsheet and an e-mail thread.Two business models, both already built. Run it as a hosted service and charge per company, with plans, per-feature purchases and payment webhooks already working. Or licence it as self-hosted software to businesses that will not put their pricing and commercial terms on a vendor's server: manufacturing, defence supply chains, legal and regulated industries. The second market pays more per sale, closes slower, and is barely served, because almost nothing in this category can actually be self-hosted. Seam is one process, one file-based database and two dependencies, which is what makes that route real rather than a claim.The record itself compounds. Every completed order builds a company's verifiable trading history inside the platform: how fast it delivers, how fast it pays, how often it hits agreed dates. That record is portable and cryptographically signed, and it gives a company a reason to invite its counterparties in rather than just use the tool alone. A buyer who leans into this has a network effect available that a pure workflow tool does not. Obvious additions, none of them required to launch: native mobile apps against the existing API; connectors to SAP, Odoo or Microsoft Dynamics for larger buyers; a reseller channel through accountancy firms and industry associations; and a contract with a qualified trust service provider to sell eIDAS-qualified signatures as an upsell, since the CSC API v2 integration for that is already written and tested. What a buyer must supply honestly: a domain, an outgoing mail provider, and distribution. There is no audience, no waiting list and no brand recognition to inherit. The engineering is done, tested and documented. The market work starts at zero.

What's included

Source code, All related design work

Exclusive rights. The sale transfers full ownership: all rights, title and interest in the source code, the name, the design and the trademark. The seller retains no licence and keeps no copy in use. The repository carries an all-rights-reserved licence written for exactly this kind of transfer. Included with the code: The Git repository with its full commit history, so a buyer can see how every part was reasoned about and changed, not just the final state. The test suite: 2,204 automated checks across 44 files, with a single runner. It tests a live instance, not mocks. A deployment kit: Dockerfile, fly.toml for Fly.io, a systemd unit, and a one-command installer that sets up Caddy with automatic HTTPS on a bare VPS. Operator tooling: an encrypted-backup decryptor, a two-factor lockout recovery tool, a demo-data purge that walks the foreign-key graph, a health endpoint and an alert hook. The demo instance generator, which builds a fully populated multi-industry showcase from scratch in one command. It is what every screenshot in this listing was taken from. The screenshot pipeline itself: a headless-browser tool that re-photographs the whole product in any of the 13 languages, plus the generator that builds the gallery page from those images. A buyer can regenerate all marketing imagery after rebranding, without a designer. The logo as SVG and as PNG and JPEG at 32, 64, 256, 512 and 1024 px, with transparency. Documentation: install and deployment guide, architecture notes, and a README in English and Bulgarian. The complete 13-language translation set, which alone represents substantial work and is the usual reason this kind of product stays single-market. No customer data is included because there are no customers. The only database that transfers is the demo one, generated by a script.
