12 resources
Managing the Professional Service Firm
David Maister
Still the clearest map of leverage, utilisation, and why talent systems beat slogans. Dense, but worth keeping on the shelf.
Best for: Founders building delivery structure for the first time.
Profit First
Mike Michalowicz
Simple cash allocation that works for project income. Ignore the hype tone; keep the bank-account discipline.
Best for: Studios mixing tax, payroll, and owner pay in one account.
This Is Marketing
Seth Godin
Useful for agency positioning when the work is strong but the story is fuzzy. High signal on empathy and smallest viable audience.
Best for: Owners rewriting their offer and niche.
Built to Sell
John Warrillow
Forces productised thinking even if you never sell the agency. Excellent on founder dependence and repeatable offers.
Best for: Owner-operators stuck as the bottleneck.
The E-Myth Revisited
Michael E. Gerber
Classic reminder that working in the business is not the same as building one. Take the systems lesson; skip the franchise dogma.
Best for: Creative founders allergic to process.
Company of One
Paul Jarvis
Permission to stay small and profitable. Especially relevant for boutique studios that confuse headcount with progress.
Best for: Agencies choosing depth over scale.
Notion
Notion Labs
Flexible enough for ops docs, proposals, and light CRM. Dangerous if everything becomes a wiki nobody maintains.
Best for: Teams that need one shared workspace without enterprise IT.
Asana
Asana
Clear ownership and timelines for client work. Stronger than a chat thread; lighter than enterprise PM suites.
Best for: Studios of 5–20 running parallel projects.
Xero
Xero
Clean bookkeeping for project agencies. Pair it with a weekly cash view and it becomes a decision tool, not just compliance.
Best for: Agencies ready to stop living in spreadsheets alone.
Harvest
Harvest
Time tracking that helps pricing and capacity without feeling like surveillance. Useful for fixed-fee margin reviews.
Best for: Teams that sell hours or need honest project costings.
HubSpot CRM
HubSpot
Free tier is enough for a small pipeline if the team updates stages weekly. Do not turn on every automation on day one.
Best for: Owners escaping inbox-as-CRM habits.
Figma
Figma
Default creative collaboration layer for modern studios. Treat file hygiene and permissions as part of delivery quality.
Best for: Design-led marketing and creative teams.
Every book and tool here is judged against a small agency: limited admin time, uneven cash flow, and client work that cannot wait for a complicated rollout. If it is not listed, it has not earned a place yet. Where a partner or affiliate relationship exists, it is disclosed on the resource page and never decides whether something is recommended.
