ScreensConcept
Desktop and mobile: Finance and operations teams configure modules and import data at desks, while field and approval work happens on phones; both are core workflows. Sample screens on a computer and a phone, in the proposed brand. Their numbers are sample data.

About this appAI proposal
Tallyhouse is a modular business system for growing companies. Start with one module, such as invoicing, customers or stock, and add others when you need them. You pay only for the modules you switch on, not for a whole suite.
It runs as an installable web app on phones and desktops, with a clean interface and an API behind every screen. Teams with developers can self-host it. Teams without can use managed hosting.
It is for mid-sized companies and their in-house developers who find large ERP suites too heavy and open-source alternatives dated. Each module is small enough to read, change and test, so custom workflows do not become a long project.

- Why this name
- A tally is the old way of counting what the business holds, and a house suggests rooms you add one at a time.
In the first version
Members say which features they would use. It tells PWAS what people want; it changes no score.
Switch on only the modules you need
Finance, customers, stock and purchasing are separate modules. Enable one at a time and pay only for those in use.

What it could be worthEstimate
What a software business making this much sells for today, from real deals. Pick a monthly revenue.
If it makes
Worth about
$194,000
Sale range $132,000 to $263,000
$120,000 a year in revenue
From 87 software businesses listed and sold on Empire Flippers in the last year, revenue vetted by the broker: they sell for about 19× their monthly revenue, most between 13× and 26×.
Measured on profit, the middle deal is 32× monthly net profit: about 2.7 years of profit.
An estimate, not an offer or financial advice. A real price depends on profit, growth, churn, how much of the work is the owner's, and the buyer.
How it would growAI proposal
How the product would reach new customers through its own use, and how the first ones would be found. A plan to test, not a result.
- Built-in loop
- No loop in the product. It reaches customers through the open-source project, developer content and direct sales. Self-hosting teams find it through the code repository and guides.
- Do they become customers?
- Developers who try the open core may later buy managed hosting or support, but this is not proven. Test how many self-hosters convert to paid plans.
- First customers
- Small wholesale and distribution companies with 20 to 100 staff and one in-house developer, outgrowing spreadsheets or a dated open-source ERP.
- Where to reach them
- Open-source communities: Publish the core, a migration guide from ERPNext and Odoo, and answer questions in developer forums.
- Direct outreach: Contact operations managers at distributors and offer a free pilot of one module.
- First milestone
- Five paying companies in one vertical on managed plans within three months of the first release.

RisksAI inference
- CommercialCompanies may keep paying for Odoo or ERPNext rather than switch. The open core must give a clear reason to move, and one module has to be good enough to win alone.
- TechnicalAccounting rules, tax and stock costing differ by country. Supporting more than one region early could stall the first version.
- CommercialGiving away a self-hosted core may leave few buyers for managed plans. The split between free and paid modules needs testing.
- DataMigrating from existing systems is messy. Poor imports could stop a company from adopting it.
- RegulatoryHolding financial records brings duties on security, backups and retention that differ by market.
