Seller story卖家故事

I built InvoiceNest after sending my own invoices from a messy spreadsheet. It grew slowly through consultant communities. I’m selling to focus on a full-time role and don’t want a neglected product. The codebase is intentionally small — features that don’t reduce invoice friction were cut.我在用混乱表格开票后做出了 InvoiceNest。它通过顾问社区缓慢增长。出售是为了投入全职工作,不愿让产品荒废。代码库刻意保持精简——不能降低开票摩擦的功能都砍掉了。
