But in 1928, a machine was developed that revolutionised accounting. Balancing the books became faster and cheaper.
Business growth and rising costs meant that more efficient and cost-effective processes were needed. The new accounting machines could complete the work more quickly, using fewer staff.

But the last branch was only mechanised in 1962.
