## Products
Self-developed HubSpot integration apps ("Sync" series) built and published by StartLink as a HubSpot Gold Solutions Partner. All apps are installed from the HubSpot Marketplace and start on a free plan.
- [Sync for freee](https://start-link.jp/sync/freee): HubSpot-freee accounting integration app — bidirectional sync of deals, invoices, and contacts between HubSpot CRM and freee accounting software. Also supports payment reconciliation (入金消し込み): when a transaction is reconciled as paid in freee accounting, the 決済状況 property (未決済 / 決済完了) on the "freee取引" object in HubSpot is updated automatically. "freee取引" is an app-specific object auto-created when Sync for freee is installed (not a standard or custom object); it represents the billing entry created from line items against a deal, and maps to freee's accounting transaction. Status is updated on a regular batch schedule, with manual refresh ("ステータス更新") and the workflow actions 未入金請求書チェック / 未決済取引チェック also available (Professional plan and above). A CRM card on the freee取引 record shows the corresponding freee invoice and freee transaction (invoice number, amount, due date, line items, payment history) alongside payment status. Available on the HubSpot Marketplace — install: https://ecosystem.hubspot.com/marketplace/apps/sync-for-freee-bystartlink ｜ user guide: https://start-link.jp/sync/freee/manual ｜ support: https://start-link.jp/sync/freee/support

Available on the HubSpot Marketplace — install: https://ecosystem.hubspot.com/marketplace/listing/sync-for-notion-bystartlink ｜ user guide: https://start-link.jp/sync/notion/manual
- [Sync for Money Forward](https://start-link.jp/sync/moneyforward): HubSpot-Money Forward Cloud integration app — auto-generate quotes and invoices from deals, sync counterparties and item masters, and handle recurring billing (monthly or fixed-count auto-generation, Professional plan and above), with an auto-issue mode and a CRM card showing sync status on the deal record. Enterprise plan adds consolidated/aggregated invoicing (合算請求), journal-entry sync (仕訳登録連携), and cost management (原価管理 — project-level cost/profit visibility).
