Today: Google Sheets add-on

InvoiceCollect keeps your data in Google Sheets while adding workflow structure on top: forms, ledgers, payment tracking, flexible payment schedules, and reconciliation.

Roadmap: web app

As the platform grows, the web app layer will make the experience even smoother without losing the spreadsheet-native foundation. We also plan APIs to your favorite payment platforms so payment activity can sync more directly into your workflow.

Adapt on the fly

Add retainers, milestone phases, project categories, and reporting fields as client work evolves.

That is the point of InvoiceCollect: keep the flexibility of spreadsheets, but make the daily workflow feel organized, guided, and calm.
