A store-use account is a charge-account customer that represents your store itself — you ring up mistints, colorant, break-room cleaning supplies, and anything else consumed internally against this account instead of a real customer. Every store-use sale removes the inventory from the books, posts a $0 charge-account invoice, and leaves a paper trail for your accountant at year-end.
In the POS mode, open Customers in the left sidebar.
Mistints, colorant waste, and break-room supplies all pull from the same inventory your customers buy from. Without a place to record that usage, your on-hand counts drift — the paint is gone but Rundoo thinks it's still on the shelf — and you lose the tax write-off that internal-consumption inventory qualifies for.
A store-use account fixes both:
From the Customers list, click Add customer and fill in the modal. A few store-use specifics:
Store Use, {Location} — Store Use, Paint 123 — Mistints, {Location} — Colorant. If you run multiple categories of store consumption (mistints vs. colorant vs. cleaning), one account per category is cleaner than one catch-all.See Customers for the full Add customer walkthrough.

Once the account exists, open it and click the Settings tab. Scroll to Financing and set a charge-account Finance term — Net 1 Statement is the standard pick for store-use accounts, since the goal is to close the zero-dollar invoices the same month they post. Set a modest Credit limit ($1,000.00 is typical) to keep the account behaving like a real charge account without blocking anything in practice. Leave Finance charge as No finance charge — you're not paying yourself interest.

Setting a statement-based Finance term is what turns the account into a charge account — without it, the Charge account tender won't unlock at POS. See Finance terms for how the terms themselves work.
