Invoice Generator

Invoice Generator

Produce an invoice the user can send within a minute. Output is a self-contained HTML file (prints cleanly to PDF from any browser) plus a markdown copy for records.

Step 1 — Load context

Read .solo/business.md. You need: business name/name, payment terms, payment methods, tax notes, currency, hourly/day rate. If missing, ask for only the missing fields — do not run the full setup.

Step 2 — Invoice number

Look in invoices/ for existing files named INV-<number>-*.{html,md}. Use the highest number + 1. If the folder is empty, ask the user for the starting number (default INV-0001). Never reuse a number.

Step 3 — Line items

Accept any of:

• A time log (from /time-log or pasted): group by task/day, multiply hours by rate.
• A list of deliverables with fixed prices.
• A milestone from a proposal/SOW ("50% deposit for X").

Confirm the total with the user before writing if you had to make any assumption (e.g. which rate applies).

Compute: subtotal, tax (only if business.md specifies a rate; otherwise none and say so), total. Due date = issue date + payment terms (default net 14).

Step 4 — Write the files

Write invoices/INV-<number>-<client-slug>.html and .md.

HTML requirements: single file, no external assets, system font stack, prints on one A4/Letter page, @media print hides nothing important. Layout:

<Business name>                                    INVOICE
<address / email / website>                        INV-<number>
                                                   Issued: <date>
Bill to:                                           Due: <date>
<Client name>
<Client contact / address if known>

| Description | Qty | Rate | Amount |
|-------------|-----|------|--------|
| ...         |     |      |        |

                                       Subtotal   <amount>
                                       Tax (<x>%) <amount>   (omit row if none)
                                       TOTAL      <amount>

Payment: <methods from business.md>
Terms: <payment terms>. <Late fee policy if any.>
<Tax/VAT note if any.>
Thank you.

Keep it plain. No logos unless the user provides a path; no colors beyond one accent for the total.

Markdown copy: same content as a table, for the user's records and for /monthly-finance-summary.

Step 5 — Hand off

Report: file paths, total, due date. Offer a 3-sentence cover email in the business.md tone ("Invoice attached for , total , due . Let me know if anything needs adjusting.").

Do not

• Do not guess tax rates. If business.md is silent, no tax line, and say so.
• Do not reuse or skip invoice numbers.
• Do not put bank account numbers into the file unless they are already in business.md or the user pastes them for this invoice.
