Sales Type D

This Sales code records income the business earns from sales type d. As an income account, it normally carries a credit balance: credit entries increase the balance (recording new income) and debit entries decrease it (for example, a credit note issued to a customer).

Real-world examples

Construction (new build vs. repair and maintenance)

A building contractor works on both new-build housing and repair/maintenance jobs, which are taxed completely differently — constructing a new dwelling is normally zero-rated for VAT, while repair and maintenance work is standard-rated at 20%. Repurposing 4100 for new-build sales, leaving another code for repairs, makes it easier to see the VAT treatment is being applied correctly: a zero-rated new-build invoice for £18,000 posts as a debit of £18,000 to 1100 (Debtors Control Account) and a credit of £18,000 to 4100, with nothing posted to 2200 (Sales Tax Control Account) — compared with a repair invoice of the same value, which would carry £3,600 of VAT on top.

Manufacturing (splitting product lines)

A manufacturer producing two distinct product ranges repurposes 4100 to record sales of one range separately from the other, purely to see which range is actually driving revenue and margin. A batch of orders invoiced at £3,600 (£3,000 net) is a debit of £3,600 to 1100, a credit of £3,000 to 4100, and a credit of £600 to 2200 — mechanically no different from any other sales code, just relabelled to match how the business wants to see its own numbers.

Commonly confused with

Because code 4099 (Flat Rate — Benefit/Cost) sits right next to this one in Sales, it's a common mis-posting target. Code 4100 is specifically for sales type d, while 4099 covers flat rate — benefit/cost — similar in nature, but keeping them separate is what makes the sales section of your management accounts meaningful rather than a single lumped total.

What a mis-posting here costs you

A sale posted to the wrong Sales code won't change total turnover, but it will distort the sales analysis used to see which products, services or channels are actually driving revenue.
