About Brackish Books

A financial planning tool for small commercial farms.

What it is

Brackish Books is two sister apps under one roof. Tides serves aquaculture operators — RAS systems, pond farms, open-ocean and nearshore shellfish, and wild harvest businesses. Tilth serves agriculture operators — mushroom growers, market produce farms, orchards, and small livestock operations.

Both apps share the same financial engine: per-product pricing with margin and break-even analysis, enterprise budgets, integrated cash-flow planning, and annual projections that tie revenue, COGS, overhead, and ending cash together.

Who it's for

Owner-operators, farm managers, and bookkeepers at small commercial farm and harvest businesses. The platform is designed for adults running real operations. It contains no advertising, no social network, no messaging between strangers, and no public user-generated content — making it appropriate for use on school, workplace, library, and other managed networks.

How it's built

Brackish Books is built on modern web infrastructure with row-level data security so each workspace's records stay scoped to its own team. All traffic is served over HTTPS.
