Consultants and professional firms
Fees billedon time, every month.
Consultancies, CA and legal practices, architects and advisory firms: professional fees under SAC, retainers raised on the day, and a statement each client can open without writing to ask for one.

Northfield Organics — monthly retainer
On the day
Numbered on 01 Oct and the link is emailed to the client the same morning.
Next three
01 Oct 2026 · 01 Nov 2026 · 01 Dec 2026
Dates are counted from the start date, not from the last run — so a schedule on the 31st doesn't drift to the 28th and stay there.
Sample · a start date in the past never back-bills
No. 01How it works
A retainer, end to end.
- 01
Engagement letter as a quotation
Accepted from a link, so the scope and fee are on record.
- 02
The retainer
A recurring invoice, issued and emailed on the day you chose.
- 03
The statement
Per financial year, in the client portal or from the link.
No. 02What firms use most
Quiet, exact, on schedule.
SAC on every line
From the item, with the rate; the HSN summary prints underneath.
Recurring invoices
Monthly, quarterly or yearly; pause or skip one when an engagement pauses.
Credit notes
A fee reduced after the invoice went out, with GSTR-1's reason and its deadline.
Several businesses
A practice and a separate consultancy, each its own workspace under one login, on Business and Enterprise.
