Firing cost billing
Bill firing costs without paper slips or spreadsheets
Set up your pricing model once and log every piece in seconds. At the end of the month the billing is ready, without you adding anything up.
Your pricing model, your rules
Per kilo, per piece, tiered by temperature or a flat rate. You pick a template and add your own rules: minimum price, member rate, included quota.

Supported pricing rules:
- Per kilo
- Temperature tiers
- Minimum price per piece
- Round up per started kilo
- Member vs. non-member rates
- Included allowances
- Fixed-price exceptions (e.g. plates)
- Per-piece extras (e.g. glaze)
- Express surcharge
Log pieces while the kiln is being loaded
Pick the member, type the weight, the price is there. On your phone, right next to the scale.
- Price appears straight away, by your rules
- Included quota is deducted as you save
- A photo per piece, when you need one
- Correctable while the firing is still in preparation

Every number stays traceable
Every price is stored as a snapshot: weight, plan, the rule applied, the quota used. Change your price list later and past billing stays untouched.
- Weight, plan and rule stored per line
- Past firings do not shift with the price list
- Answer questions from the line, not from a spreadsheet

Monthly billing and export
One summary per member: membership fee, firing charges, paid or open. A CSV export goes to your accountant.
- Membership fee and firing charges in one summary
- Paid status per line
- Member and external rates shown separately
- CSV export for accounting, Lexoffice and sevDesk are planned
