By Best SOP Software editorial team · 2026-07-10

Last updated July 10, 2026

TL;DR

Agencies scale on SOPs — onboarding, reporting, handoffs, content approval.
The differentiator: brand-kit support so client SOPs come out on-brand.
Best pick: Haiku — brand kits at Pro, desktop capture on free.

Start with the agency client onboarding template.

The SOPs every agency needs

Client onboarding — from signed contract to kickoff.
Monthly reporting (per service line).
Deliverable handoff (creative → client).
Content approval loop.
New service-line launch.
Client offboarding (contract end, IP handover).
New-hire onboarding (agency side).
Weekly ops review.

Why brand kits matter for agencies

Client-facing SOPs need to feel like the client's own docs, not yours. Tools without brand-kit support force you to manually edit every SOP or ship them with your agency's logo — either is a bad look. Haiku applies brand kits automatically at export time; Tango matches on Pro.

Tools ranked for agencies

Tool	Brand kits	Client-friendly export	Verdict
Haiku	Yes (Pro)	PDF + web + JSON	Top pick
Tango	Yes (Pro)	GIF-style + PDF	Runner-up
Scribe	Yes (Pro)	PDF + web	Solid but pricier
Trainual	Yes (Team)	LMS-style	Only if you sell training

Structure per client

Don't create separate SOPs per client — one SOP per service line, with client-specific config in a linked doc. This keeps the SOP library at a manageable size and lets you improve the SOP once and benefit every client.
