The Digital Home of Addviser +

Practice development for professionals in The Americas

Addviser+ is a community of progressively minded accounting firms, based in The Americas, who wish to benefit from best practice in developing a 21st-century practice from both each other and the members of the Addviser+ advisory board.

Membership in Addviser+ offers a series of value propositions which makes investing in membership a cost-neutral position for the firm in real terms.

Addviser+ was established to deliver what I'm often told that members of other 'clubs' are looking for but with the added bonus of being able to upgrade to certain special interest communities such as People, Fee Growth, Marketing, Technology as they desired.

The Adddviser+ Vault has been specifically established to support accounting firms through the three tiers of the Addviser+ membership.

In addition, access to The Vault is available to firms globally who are not able to take advantage of in-person events and consultations which are also available within the membership.

Membership to Addviser+, at whichever level of membership, is aimed at the hungry, proactive and caring accounting firm, irrespective of their size and irrespective of their location.

Addviser+ Digital Access

The Addviser+ Membership is more comprehensive than solely access to the Digital Vault alone but to meet demand, I am delighted to offer our Online Membership access through either the Addviser+ 'Vault Only' package and the Addviser+ Remote Access Package.

The Addviser+ Vault itself is the knowledgebase and is available to all members of the Addviser+ Professionals. The content in The Vault serves the accounting profession globally and is available to firms based both in The Americas and elsewhere globally.

The Addviser+ Vault gives your organisation unlimited access to my vault of propriety online training content (approx. $150k of practice development training if purchased for in-person delivery).


For Firms Who Aspire Maximum Growth

For accounting firms who aspire to achieve maximum practice growth, beyond the online packages, there is an upward level within the Addviser+ Membership available to firms and organisations as they expand into six or seven-figure practices.

Aimed at firms in The Americas, these higher-level tiers include in-person consulting with me and access to our Expert Partners.

If after reading the information here, you would like to find out more about the full-level tier membership, then I would invite us to have a conversation and please do get in touch with me at martin@upwardspiralpartnership.co.uk

Meet Martin Bissett

Leading the Addviser+ Professionals Community


Martin Bissett is the founder of the Upward Spiral Partnership, the international consulting firm that specialises in enabling the accounting profession to win higher-end clients, create leaders from their ranks and save lives.

His professional purpose is to alert the accounting profession to the profound outcomes that their advisory expertise can create in the lives of their clients.

At the same time, he also alerts the accounting profession to the profound difficulties that can arise in the lives of their clients when they choose not to educate their clients about the impact that their advisory expertise can have.

The Upward Spiral Partnership is the 4th business Martin has played a key role in building and the first of his own. 

In the first 5 years of USP, Martin has: 

  • Been engaged/retained by 4 of the World's Top 10 Accounting associations and 6 of the Top 10 in the UK. 
  • Authored 9 books including Passport to Partnership, content from which has been adopted into the curriculum of AAT Level 3 courses, and taught in selected UK colleges and US CPA Societies.  
  • Been retained by Accountingweb as a judge of their prestigious practice excellence awards for three years in a row. 
  • Been highlighted as ‘one to watch’ in AccountingToday’s Top 100 Most Influential countdown for 2 years running. 
  • Spoken on 4 continents. 
  • Created several trademarked items of intellectual property including the ACCOUNTS™ system and ‘Martin’s Relationship Pricing™’ Model. 
  • Written for several professional publications including AccountingToday, AccountingWeb, CPA Practice Advisor and Chartered One. 
  • Sat on many international expert panels and guested on professional podcasts in the US, UK, and Australia. 
  • Sits on a parliamentary steering committee tasked with bringing advisory services to the fore in the accounting profession.


The outcome of Martin’s work is profitable new business for the practices he is engaged by, alongside the fine-tuning of teams of partners and emerging leaders who can develop new business by increasing their commercial awareness for themselves, without significant ongoing third party assistance. 

Previously, Martin served 10 years as a director (appointed at age 26) on the board of a marketing consultancy firm serving the accounting profession. There, he held the responsibility for the growth of the client base including six of the U.K.’s top 30 accountancy firms. 

He now coaches, mentors, speaks, trains and consults with accounting firms worldwide.

In total, he has worked with over 1800 firms of accountants and found it unnecessary to keep track of his contributions to the new business growth of those firms once it surpassed £500m collectively.

  • "It's great to have a blueprint to follow"

    What I find most valuable is it breaks down advisory into manageable steps and ties corresponding pieces of the Addviser+ programme to those steps. The programme has so much to offer that it's great to have a blueprint to follow now. So much info to work with all at your fingertips.
