Barb the Bookkeeper

Ask Barb for this period's VAT201, who owes you money, or why a figure is what it is. She looks it up in your own books with your permissions, shows her working, and leaves a draft for a person to check and submit.

Prepare my VAT201 for September and October.
The draft is ready for Karoo Kettle Co, tax period 202610. It's a refund:
Output tax (field 13)R3,150.00
Input tax (field 19)R11,700.00
Refundable (field 20)R8,550.00
The refund comes from the enamelling kiln: R9,000.00 VAT on a capital purchase, in field 14. All 7 transactions are classified. Open the draft, check it, and submit it when you're happy.
Why is the UK design work in field 2?
A service to a non-resident is zero-rated under section 11(2)(l) of the VAT Act, so it carries no VAT but still belongs on the return, in field 2 (GEN-ELEC-04-G01). Confirm with your accountant that the client is not in South Africa when the service is supplied.

Illustrative, from the Karoo Kettle demo. Karoo Kettle Co is a fictitious company.

01 · What she does

The work a good bookkeeper does first, drafted for you

Prepares the VAT201

Builds the return for the period from your invoices and journals, field by SARS field, and tells you what's left unclassified.

Explains a figure

"Why is field 14 R9,000?" She traces it to the invoices behind it and links each one.

Debtors and creditors

Who owes you, for how long, and who to chase first. What you owe and when it's due.

Reports on request

Trial balance, profit and loss, balance sheet, general ledger, registers: run, read and summarised.

The document on your screen

Open an invoice and ask about it. She sees what you see, nothing more.

Coming next in build

A photo of a supplier slip into a draft purchase invoice with the right VAT template; bank matching; a month-end checklist.

02 · What she won't do

Limits you can read, and an accountant can check

Submit, cancel or delete

Everything she prepares is a draft. A person checks it and submits it.

Pay, send or file

She never pays a supplier, emails a customer or files with SARS.

See past your permissions

She works as you, through ERPNext's own roles and company permissions. Separate companies stay separate.

Guess

She looks every figure up, names her source for every tax rule, and says so when a question needs your accountant.

03 · Her sources

She cites the official documents

Barb is not a registered tax practitioner. For a judgement call she explains the rule, names the source, and suggests you confirm with your accountant.

04 · How it works

Your books stay in your ERPNext
