Can a Third-Party Digital Billing Company Put Big Savings on the Bottom Line?

In a recent article, we broadly confirmed that a general claim of the international billing and payment research companies was true for two companies (one small and one large) and that it is therefore likely to apply more widely. This claim is that on average every organisation spends around 5% of its revenue on issuing invoices and collecting payment for them. Now that we believe this claim to broadly accurate, in this article I want to test the claim of some third-party electronic billing and payments companies that they can make cost savings of up to 50% if their clients adopt a fully digital billing and payment service. At the full 50%, this would mean that up to 2.5% of a given company’s revenue would be saved. And as the large company in our previous article had an annual turnover of £90 million, this would amount to a whopping £2.25 million (and that’s certainly worth having as recurrent additional income).

To properly analyse this situation, we first need a few facts. In the information below therefore are some statistics about the company which we called Beta in the earlier article:

What this chart tells us immediately is that Beta spends slightly more than 5% of its revenue on issuing invoices and getting them paid, with 43% of this £4.62 million cost being on the staffing side and 57% being on the transactional cost side. So, now that we know this, where is the particular scope for savings, taking each of these two headings separately?

A) The Staff side savings potential
By moving to a fully digital billing solution, there is an expectation that many more people will be happy to both get/view their bills or invoices on line and pay them by the same means. However, this is not going to be the case for all customers and even for those who do make the transition, it takes time. For our purposes here we will therefore estimate potential take up after a three year period, at which point, 50% of Beta’s customer base is happy to view their bills online and half of these (or 25%) are happy to pay online. For simplicity we could say that this is a switch of 35% of the customer base to online billing and payment (the other 65% staying with previous practices and methods).

The implications of the above is that Beta cannot cut or redeploy its staff too aggressively, as the majority of customers still need to be serviced in the old way. However, we can nevertheless estimate that staff man-hours necessary to tackle the new workload (and therefore numbers needed) are reduced as follows:

Accounting: The 50% of customers now viewing their bills on line and the 25% paying by online means, allow much easier settlement and reconciliation, with electronic records at every step, less errors and much easier analysis of data (because the digital billing system can be used for the entire customer billing process and not just part of it). As a result, the people handling invoicing and payments could be reduced to a manager plus four accountants at Beta (a reduction in staff of 38%).

Clerical staff: Quite high numbers of clerical staff are needed at Beta to handle the 25% cheque and cash mix, general data entry (with records often being keyed two, three and even four times on occasions) banking and the chasing of invoices when overdue. Because there is also likely to be faster payment in the electronically paying customer base, this reduces the amount of time chasing late payments. In summary, data administration is simplified considerably across the whole system. As a result, the people handling invoicing and payments could be reduced to a manager plus fifteen clerks at Beta (a reduction in staff of 39%).

Call-centre staff: 50% of all Beta’s payments are taken on the phone, where service agents have to find the customer data and invoice, take the payment manually and payment data to a system of some kind. With a fully digital solution being used by 50% of the customer population, and half of these paying on line, the burden on the call-centre is reduced by 25% (as there is no need to contact the call-centre anymore for these customers). In addition, call-centre staff may be able to convert more and more customers to online payment by showing them the digital invoicing and payment system and pointing out that this is available 24/7, 365 days of the year-and not just 9am-5pm call centre hours. As a result, the people handling invoicing and payments could be reduced to a manager plus forty agents at Beta (a reduction in staff of 30%).

All of the above adds up to staff savings (even with a lower overhead recovery now of 40% as there are less offices, desks, computers etc needed) of £730,056.

B) The Transactional cost side savings potential
We have assumed no change in Beta’s business in terms of revenues and overall transactional volumes (and therefore average cost of each transaction). There are, however, two major changes that a digital system is likely to bring:
1. A change in bill presentment costs
2. A change in the mix of payment types being used

Bill presentment costs: Now that 50% of the customers are viewing their bills on line, it is reasonable to assume that they are happy to see paper “turned off”. As Beta were emailing invoices previously this was a preparation cost mainly (on the staff side) but it does allow the opportunity to send statements electronically as well as give customers copy invoices in the new digital system forever as a free service. This means that paper and envelope costs would reduce, as well as the need to store physical paper copies within the Beta organisation or externally (so costs of storage space are reduced also). Perhaps more significantly, the marketing material send in the post by Beta can now be put online for half of the customers (where it is presented without the cost of having to send it out). All up, savings in all of these presentment areas for Beta are estimated to be £481,035 per annum.

Payment costs: In the new world, a fully digital presentment and payment solution is likely to half Beta’s volume of cheques and eliminate the use of cash completely (even though the option to pay by cash may still be available to customers in some solutions –such as the one offered by PaySwyft). On line bill payment however goes up to become 15% of the total mix (with the other 10% coming from credit and debit card payments that used to go through the Beta call-centre). This adds a transactional cost of £0.50 per invoice to Beta, or £116,379 per annum, but it is more than offset by savings elsewhere. The greatest of these is in the float costs of the business. Because online payments are known to get to customers quicker and lead to faster payment, cash flow is accelerated and days outstanding are reduced (in Beta’s case from 45 days to 38 days (a drop of 22%). This contributes a total of £123,288 in annual savings to Beta. In addition, the often linked costs of having to handle bounced cheques, chasing debt and writing off unpaid invoices, diminishes considerably, adding another annual saving of £387,931.

If we add all the transactional side potential savings up, the total is £924,908

Summary
So, on the staff side we have estimated total savings of £730,056 and on the transactional cost side estimated total savings of £924,908. This makes a grand total of £1.652 million in savings per annum (recurrently) or 1.84% of revenue. Hence, the claim that a good digital billing system can save a company 50% of its costs (or in this case 2.5% of revenues) is not quite met here. However, with the potential to add more savings over future years as more and more customers switch to the new online system it would get very close to the 50% target and make the switch to digital billing still seem like a very good idea.

To make the above figures easier to see at a glance, a summary of all of the above is presented in the table below:
