Invoicing App for Butcher Shops: Wholesale Statements by Weight

An invoicing app for a butcher shop has to bill what came off the scale, not what was ordered. Describe your wholesale accounts and how you deliver, and Mythex builds an app that logs each delivery by weight, rolls the week into one statement per restaurant, and produces PDF invoices and credit notes.

Who it's for

Butchers who supply restaurants, cafes or caterers by the case and currently bill from a word processor, a spreadsheet or the back of delivery tickets, and who spend the end of each month chasing who paid for what.

What you can build

Wholesale accounts with delivery days, payment terms and a kitchen contact
Delivery notes listing each cut, actual weight and price per pound or kilo
A weekly statement per restaurant listing every delivery
Credit notes for short weights or returns, linked to the delivery
PDF invoices with your numbering, logo and tax
An overdue list showing who owes what this week

Bill from the scale ticket

A chef orders about twenty pounds of short rib; you cut and ship 21.4. If the invoice says twenty, you lose money, and if it says twenty-one point four without proof, you get a phone call. Log each delivery with the weighed amount for every line, and print or share the delivery note when it goes out. The invoice then matches a note the kitchen already signed for, and the monthly argument about what was delivered goes away.

Weekly statements instead of a pile of invoices

Most restaurants would rather pay once a week or once a month. Keep each delivery as its own record, then ask for a statement per account that lists them with dates and totals, and a due date based on that account's terms. One email a week replaces five, and you can see at a glance which account is falling behind.

Credit notes and price changes

Short weights, a returned case or a cut that did not meet the chef's spec should become a credit note tied to the original delivery, so the history makes sense later. Wholesale prices move with what you pay at market; store a price list per account with a start date, so old deliveries keep their old price when you raise it.

Retail invoices too

The same app can invoice private customers for a whole lamb, a hog roast or a large party order, with a deposit taken at order and the balance after weighing. Keep retail and wholesale customers as separate types so your wholesale dashboard shows only trade accounts.

A prompt to start from

Build an invoicing app for my butcher shop's wholesale accounts. Each restaurant has delivery days, payment terms, a contact and its own price list. I log each delivery with cuts, ordered quantity, actual weight and price per kilo. Every Friday each account gets one statement listing that week's deliveries as a PDF. Add credit notes linked to a delivery for short weights, and a dashboard of overdue balances.

Questions

Can I invoice by the actual weight delivered?

Yes. Each delivery line has the ordered amount and the weighed amount, and the invoice uses the weighed amount at that account's price.

Can restaurants get one invoice a week?

Yes. Deliveries are logged separately and grouped into a weekly or monthly statement per account, with every delivery listed on it.

Does it produce a PDF?

Yes. Ask for a printable layout with your logo, numbering and tax, and download it or attach it to an email.

Does it handle tax?

Tell Mythex which rate applies and it is worked out per line and shown in the total. If some items carry a different rate, say so and it can apply rates by product.

Do I need to know how to code?

No. You describe how you bill and Mythex builds the app with a live preview. Changes are made by chatting.

How much does it cost?

There is a Free plan with daily credits and no card. Pro is $25/month and adds code editing, export, a custom domain and credit top-ups.
