Vibecode Gastrosync
track this build5 steps, step by step0%KINDA · weekend project
A single venue can replace the Word, spreadsheet, and inbox loop in a weekend: capture an event enquiry, price it from a small catalogue, publish an offer for acknowledgement, and keep one operational factsheet current. Gastrosync becomes much harder to replace when several locations and teammates depend on permissions, document history, reliable delivery, regional tax and invoice rules, payment slips, and legally meaningful signed records.

You are building a lean indie version of Gastrosync. Create the following project files first, then implement the application by following them. Keep the files updated as decisions change. Do not collapse this into a single README or prompt. ===== README.md ===== # Gastrosync indie build ## Goal Build the smallest trustworthy replacement for the core Gastrosync workflow for one developer or a tiny team. ## Scope Move one venue's event enquiry through contact capture, itemized pricing, a shareable offer, customer acknowledgement, and an always-current operations factsheet. ## Quick start 1. Install the documented dependencies. 2. Copy `.env.example` to `.env`. 3. Run the development command chosen during implementation. 4. Complete the acceptance checks in `BUILD_PLAN.md`. ## Honest limits This build deliberately does not replace: - multi-location authorization and team-wide shared workflows - production-grade signed-document freezing, auditability, and delivery guarantees - deep product catalogues, reusable templates, automations, and operational reporting - VAT, deposit, final-invoice, cancellation, and reverse-charge edge cases - Swiss and German payment slips plus ZUGFeRD EN16931 e-invoice behavior If those capabilities are essential, use Gastrosync instead of pretending the gap is solved. ===== AGENTS.md ===== # Agent instructions - Optimize for a working, understandable weekend build. - Prefer the fewest moving parts that satisfy the brief. - Do not invent cryptography, security guarantees, APIs, or compliance claims. - Keep secrets out of source control and logs. - Add focused tests for destructive, security-sensitive, and data-loss paths. - Run the project checks before declaring the build complete. - Record any deliberate shortcut in the README under "Tradeoffs". ===== BUILD_PLAN.md ===== # Build plan ## Original build brief Build a working single-venue event sales tool in an empty repository. Use Ruby 3.4, Rails 8, Hotwire, Tailwind CSS, PostgreSQL, and Docker Compose; do not offer alternative stacks. The core loop is: capture an enquiry, price the event, share an offer, record customer acknowledgement, and publish the current operations factsheet. Make the first run work with one documented Docker command and seed a clearly labelled demo venue. Implement one private venue account with users, contacts, events, event status, dates, guest count, rooms, notes, and an activity timeline. Add a small reusable catalogue of food, drink, room, staffing, and equipment items with quantity, unit price, VAT label, and optional notes. Let staff turn an event into a versioned itemized offer with totals, expiry date, terms, and PDF download. Publish each offer at an unguessable signed URL where the customer can review it and acknowledge it with name, email, checkbox, and timestamp. Treat acknowledgement as workflow evidence, not a qualified electronic signature, and say that clearly in the UI and README. After acknowledgement, preserve a read-only JSON snapshot and PDF while allowing staff to create a new revision. Generate a shareable factsheet from the latest accepted offer plus event timings, contacts, setup notes, dietary notes, and assigned staff. Keep the factsheet live as operations notes change and provide a print-friendly PDF. Send offer and acknowledgement emails through SMTP with retries, idempotency keys, visible delivery status, and a local mail preview in development. Provide full JSON export, daily backup instructions, audit events for every status or document change, and clear empty and failure states. Enforce owner and staff permissions on every mutation; validate inputs and never log secrets or private document contents. Write focused tests for totals, offer revisions, acknowledgement locking, permissions, and factsheet rendering plus one end-to-end happy path. Put secrets in .env, ship .env.example, and add install, test, lint, build, backup, and production-run scripts. Deliberately exclude multiple venues, granular branch authorization, collaborative editing, calendar or accounting integrations, payments, and native mobile apps. Deliberately exclude legally qualified signatures, jurisdiction-aware VAT advice, invoices, cancellation documents, QR payment slips, and ZUGFeRD or EN16931 claims. Create a README covering setup, data location, email, permissions, backups, security assumptions, and every excluded production feature. Finish by running the tests and production build and list the exact commands used. ## Required capabilities - Docker - PostgreSQL - self-hosted server - SMTP credentials for sending offer links ## Delivery order 1. Scaffold the smallest runnable application and document its commands. 2. Implement the primary data model and core workflow. 3. Add validation, safe failure states, and persistence. 4. Cover the critical path with automated tests. 5. Exercise a clean install from the README and fix every missing step. ## Done when - A new user can go from clone to first successful workflow using only the README. - The core workflow works without paid infrastructure unless the brief requires it. - Tests cover the highest-risk behavior. - Known limitations are explicit rather than hidden. ===== .env.example ===== # Copy to .env and document every variable when it is introduced. # Never put real credentials in this file. APP_ENV=development # Add only values required by the selected implementation.

The visible forms and PDFs are not the expensive part. Venues pay so every salesperson and operator sees the same event, the accepted document stays defensible, messages arrive, permissions hold across locations, and changing tax and invoice rules do not become a manager's side project.

Vibecode Gastrosync
Kinda. The core of Gastrosync is buildable in a weekend with the prompt on this page, but there are real gaps: multi-location authorization and team-wide shared workflows, production-grade signed-document freezing, auditability, and delivery guarantees. Read the honest list above before committing.
How much does Gastrosync cost?
Gastrosync's pricing is usage-based or varies by plan · No public pricing page or price was found on the official site; the site routes prospective customers to an enquiry or demo..
What do I lose by replacing Gastrosync?
Honestly: multi-location authorization and team-wide shared workflows; production-grade signed-document freezing, auditability, and delivery guarantees; deep product catalogues, reusable templates, automations, and operational reporting; VAT, deposit, final-invoice, cancellation, and reverse-charge edge cases; Swiss and German payment slips plus ZUGFeRD EN16931 e-invoice behavior. If any of those are load-bearing for you, keep paying.
Is there an open-source alternative to Gastrosync?
No mature open-source alternative worth pointing at, which is exactly why the one-shot prompt on this page exists.
