The average annual attrition rate in the SSC and GBS sector is 15-20%. Usually the person leaving will not work a lot, the person in the trial period will not contribute much and the ones training the newjoiners will have a lower operational capacity.
It is a huge loss of time, money, talent and opportunity that directly affects your Order to Cash as a whole and your profit margins.
The main way to overcome this challenge is by investing in your Talent. Engaged employees with a dynamic and fun career and an idea how they can develop will not leave you that easily, especially if they are supported in career development efforts.
That’s where We come in. You can leave this matter to us: your O2C and Credit efficiency and effectiveness will become better and you will retain highly skilled and motivated employees. Win-win-win!

Double digit overdues are a long way from a Culture of Excellence. If your numbers exceed 2.5% in any or all of: overdue %, unapplied cash, credit notes vs sales or attrition rates…
It confirms a weakness in one or more internal policy, process or procedure. There’s a lot to improve, and we’ve got a game-changing strategy. We’re using technology, industry knowledge, and a network of virtual and local experts to quickly solve each manager’s problem — from a high past due %, attrition rates or pressure to improve effciency and/or reduce costs.
At all levels, including Senior Management , the root cause is identified as „They don’t know what they don’t know”. And they will not learn it unless it is taught and showed to them. Something that we can do as your guides to optimal Working Capital and AR turned Cash.
Critical KPI objectives and career progression to senior management can only be achieved by embracing Culture, Leadership, Talent Development, Technology, Policies, Procedures, Employer Branding and Diversity simultaneously.

Big Data, Talent and Technology
READ MORE
All of you in SSCs, GBS and BPO are surrounded by Big Data. Every symbol and character on every invoice is part of it. It is a huge treasure island, but not all of it is the actual treasure. Lots of it is sand that you have to be able to navigate through to find what you are after.
It takes highly skilled individuals to interpret that data and communicate with internal and external clients to convert it into a positive cash flow. You need to know how the business works, how do your client operate, what’s relevant and value-adding and what’s not, be able to recognize the patterns and know how to act on them.
It is something that will come with 5+ years of experience or a fraction of that time spent with us.
The Callisto Grand Story
READ MORE
Founded in 2010, Callisto Grand emerged to bridge a critical knowledge gap in Credit /O2C within Shared Service Centres (SSCs) & Global Business Services (GBS). Despite the goal of being Best in Class, SSCs and GBS organizations lacked a recognized standard for success or tailored development programs—until Callisto Grand stepped in.
The brainchild of Mark Harrison, a seasoned credit professional with over 45 years of experience, Callisto Grand was built on a foundation of deep operational insights and a proven track record. Between 2005 and 2012, Mark played a pivotal role in developing the Order-to-Cash (O2C) infrastructure for two SSCs in the Czech Republic, while earning an Honours Degree in Credit Management. His extensive research, including his dissertation titled ‘Credit Management in SSCs,’ revealed a striking lack of O2C recognition and specialized training in the sector.
Recognizing this gap, Callisto Grand (formerly CZICM and ACCEE) was launched to address the unique needs of the rapidly growing Multi-National Shared Services sector. Starting with training sessions in the Czech Republic, the initiative quickly expanded across Central Europe and now garners global interest. Initially focusing on Collections, Callisto Grand evolved to provide comprehensive development for today’s professionals, emphasizing versatility and connectivity
Today, Callisto Grand offers four levels of professional qualifications, accredited Continuing Professional Development (CPD) programs, and a variety of popular workshops designed to meet the evolving needs of Credit and O2C professionals.
Boasting a team of expert trainers and dedicated support staff, Callisto Grand is driven by a shared mission: to empower SSCs and GBS organizations worldwide to achieve excellence. Through community sharing and collaboration, Callisto Grand is building the world’s largest network for Credit and O2C professionals.

From Our Founder & CEO
My professional odyssey began unexpectedly, stepping in as a Credit Controller. That moment ignited my passion for a career that spans over four decades in the ever-evolving landscape of Credit / O2C and across various work environments like Centralized, Decentralized and Global Business Services.
Callisto Grand, the name inspired by my grandfather’s houseboat, is more than an organization; it’s a celebration of the enduring enchantment found in the world of Credit. Few roles offer the unique ability to impact every stakeholder in a business positively. We believe work should transcend the confines of a 9 to 5 process or routine. Callisto Grand is committed to sharing the magic that makes each day more than just a process.
The greatest reward for my team and me is connecting with those who ‘get it’—individuals who share our passion.
We’re excited to meet you at our roundtables, conferences and training programmes sharing how you too can experience the same sense of fulfilment.
Looking forward to connecting,
Mark Harrison
