A workflow for creating a client invoice as a PDF, uploading it to Drive, recording it in Google Sheets, and adding the related bookkeeping entry. An invoice is a request for payment for goods or services.

It is for resolving a customer from the client registry, generating and issuing an invoice, logging it, and recording the journal entry.

It connects invoice creation with storage, tracking, and bookkeeping, reducing repeated data entry. It asks for confirmation before making cloud changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.01104
Opus 5.5	$0.00028	$0.00442
Sonnet 5.5	$0.00014	$0.00221
Haiku 4.5	$0.00007	$0.00110

Security

Grade A, and why

invoice scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Invoice

Runs the full bookkeeper invoice workflow with a customer-registry layer on top so an existing client's billing details are auto-filled. User-invoked only — every run writes to Google Sheets and Drive and posts a journal entry, so pause for confirmation before each cloud write.

The tool commands and their exact flags live in the source-of-truth workflow: workflows/generate_invoice.md. This skill adds customer resolution + confirmation gates around those 6 steps. Do not re-derive the flags — read that workflow.

Step 0 — Enter the project

cd /path/to/bookkeeper

All paths below are relative to this directory. Tenant: the books belong to a bookkeeper client under clients/ — default sandbox-demo. If the user says the invoice is for a different client's books (--for <slug> or by context), append --client <slug> to EVERY tool command below; the registry is then that client's clients/<slug>/customers.json. Business identity, remittance details, tax rule, and invoice numbering all come from that client's profile automatically.

Step 1 — Resolve the customer

The argument $1 is the client name (may be partial, e.g. /invoice Acme). If no argument, ask who the invoice is for.

Read tools/customers.json.
Case-insensitively match $1 against client_name / keys (substring match is fine).
- One match → show the stored client_name, client_address, currency, is_canadian_client, default_payment_terms. Ask the user to confirm or edit. If the address is blank, collect it now.
- Multiple matches → list them, ask which one.
- No match → new client. Collect client_name, client_address, currency (CAD/USD), and is_canadian_client (drives HST). Remember this is new — you'll offer to save it in Step 5.

Never silently overwrite a stored address — if the user changes it, confirm before saving.

Step 2 — Collect the invoice line items

Ask for the remaining inputs (see the input table in workflows/generate_invoice.md): services (description + amount per line), invoice_date (default today, America/Toronto), payment_terms (default the client's stored terms), optional due_date / notes. Currency and HST flag come from Step 1.
